SALES

Net sales were $975.9 million, $1.0 billion and $835.9 million in 2013, 2012 and 2011, respectively. Net sales by originating geographic area and end market are disclosed in Note 14 of the notes to the consolidated financial statements included in this Annual Report on Form 10-K, which information is incorporated herein by reference. A discussion of the risks attendant to our international operations are included in Item 1A, Risk Factors, under the heading, “International operations and sales expose us to material risks and may increase the volatility of our operating results,” which information is incorporated herein by reference.

ACQUISITIONS

We have implemented a growth strategy through continuous innovation complemented by strategic acquisitions to strengthen our product and technology portfolio with the intent of broadening our customer base and increasing our technology footprint in customers' end designs in markets where power matters, security is non-negotiable and reliability is vital. This allows us to offer an increased value proposition, gather a larger portion of the bill of materials, and engage with customers as a strategic “total solution” partner as opposed to a single socket provider. We believe this strategy strengthens our position in the industry as it protects and grows our share within those markets with the highest barriers to entry, and increases our served available market.

We have in the past acquired a number of businesses or companies, additional product lines and assets. We currently expect to continue to expand and diversify our operations with additional acquisitions that allow Microsemi to strengthen its position in high-value, high barrier-to-entry markets, while delivering increased value to shareholders and customers.

Microsemi’s acquisition strategy focuses on combining our technical talent, product portfolios and roadmaps with those companies that allow us to leverage customer synergies, expand design capabilities and increase share with key customers in the Aerospace, Communications, Defense & Security, and Industrial markets. Our customer base benefits from access to a broader portfolio of cutting-edge solutions from a single source, while adding greater scale and efficiencies to our business model. Acquisitions are an important component of Microsemi’s growth strategy and the company will continue to evaluate acquisitions that support its objectives.

On October 21, 2013, we entered into the Merger Agreement , pursuant to which, and on the terms and subject to the conditions thereof, PETT Acquisition Corp., a Delaware corporation and a wholly owned subsidiary of Microsemi, commenced a cash tender offer on October 28, 2013 to purchase all of the outstanding shares of Symmetricom’s common stock at a purchase price of $7.18 per share. We estimate that the total amount of funds required to purchase all of Symmetricom's shares pursuant to the Offer and consummate the Merger is approximately $324 million. Microsemi expects to obtain the necessary funds from credit facilities for which Microsemi has received a commitment letter as described below, alternative financing or existing cash balances. The Tender Offer is scheduled to expire on November 25, 2013.

MANUFACTURING AND SUPPLIERS

We depend on third party subcontractors, primarily in Asia, for wafer fabrication, assembly, testing and packaging of an increasing portion of our products. At the end of fiscal year 2013, approximately 90% of our wafer, assembly and test requirements are currently sourced from third party foundries and subcontractors. We expect that these percentages may increase due, in part, to the manufacturing of our next-generation products by third party subcontractors in Asia and from activity at recently acquired operations.

Our wafer designs requirements are increasing in technological complexity and in order to meet our designs specifications, our foundry partners must expend resources for capital equipment and to develop or improve manufacturing processes. Our foundry partners' inability or unwillingness to expend these resources could adversely affect our business and operating results. The assembly, testing and packaging of our products is performed by a limited group of subcontractors. Disruption or termination of any of these subcontractors could occur and such disruptions or terminations could harm our business and operating results.

We utilize third party logistics services, including transportation, warehouse and shipping services. These service providers are subject to interruptions that affect their ability to service us, including the availability of transportation services, disruptions related to work stoppages, volatility in fuel prices and security incidents or natural events at manufacturing, shipping or receiving points or along transportation routes.

We generally do not have any long-term agreements with our subcontractors. As a result, we may be unable to directly control our quality assurance and product delivery schedules. The cost of product replacements or returns and other warranty matters in connection with quality assurance problems caused by third party subcontractors could materially adversely affect us. Third party manufacturers generally will have longer lead times for delivery of products as compared with our internal manufacturing, and therefore, when ordering from these suppliers, we will be required to make longer-term estimates of our customers' current demand for products, and these estimates are difficult to make accurately. Also, due to the amount of time typically required to qualify assemblers and testers, we could experience delays in the shipment of our products if we are forced to find alternate third parties to assemble or test our products. Any product delivery delays in the future could have a material adverse effect on our operating results, financial condition and cash flows. Our operations and ability to satisfy customer obligations could be adversely affected if our relationships with these subcontractors were disrupted or terminated. In addition, these subcontractors must be qualified by the U.S. government or customers for high-reliability processes. Historically the

Defense Logistics Agency has rarely qualified any foreign manufacturing or assembly lines for reasons of national security; therefore, our ability to move certain manufacturing offshore may be limited or delayed.

In the event that any of our subcontractors were to experience financial, operational, production or quality assurance difficulties resulting in a reduction or interruption in supply to us, our operating results could suffer until alternate qualified subcontractors, if any, were to become available and active.

Our principal manufacturing operations are in the following locations:



California	Arizona	Shanghai, China
Camarillo	Phoenix
Garden Grove		Bruges, France
La Mirada	Massachusetts
San Jose	Lawrence	Ennis, Ireland
Santa Clara	Lowell
		Manila, Philippines
	Oregon
	Bend	Caldicot, United Kingdom

Many of our manufacturing and processing operations are controlled in accordance with military as well as other rigid commercial and industrial specifications. At our facilities with wafer processing capabilities, we manufacture and process products, starting from purchased silicon wafers. At our locations without wafer processing capabilities, processed wafers are sourced from third parties or our other facilities. We purchase silicon wafers, other semiconductor materials and packaging piece parts from domestic and international suppliers generally on long-term purchase commitments, that are cancelable on 30 to 90-days’ notice. Significantly all materials are available from multiple sources. In the case of sole source items, we have never suffered production delays as a result of suppliers’ inability to supply the parts. We believe that we stock adequate supplies for all materials, based upon backlog, delivery lead-time and anticipated new business. In the ordinary course of business, we enter into cancelable purchase agreements with some of our major suppliers to supply products over periods of up to 18 months. We also purchase a portion of our finished wafers from several foundry sources.

Processed silicon wafers are separated into individual dice that are then assembled in packages and tested in accordance with our test procedures. A major portion of our semiconductor manufacturing effort takes place after the semiconductor is assembled. Parts are tested a number of times, visually screened and environmentally subjected to shock, vibration, “burn in” and electrical tests in order to prove and assure reliability. As noted above, certain subcontract suppliers provide packaging and testing for our products necessary to deliver finished products. We pay those suppliers for assembled or fully-tested products meeting predetermined specifications.

RAW MATERIALS

Our manufacturing processes use certain key raw materials critical to our products. These include silicon wafers, certain chemicals and gases, ceramic and plastic packaging materials and various precious metals. We also rely on subcontractors to supply finished or semi-finished products that are marketed through our various sales channels. We obtain raw materials and semi-finished or finished products from various sources, although the number of sources for any particular material or product may be limited. We feel that our current supply of essential materials is adequate; however, shortages have occurred from time to time and could occur again.

RESEARCH AND DEVELOPMENT

We believe that continuing timely development and introduction of new products is essential to maintaining our competitive position. We currently conduct most of our product development effort in-house. We also employ outside consultants to assist with product design. We expense the cost of research and development as incurred. Research and development expenses are principally comprised of payroll and related costs, consulting costs and supplies.

We spent approximately $170.6 million, $168.5 million and $114.2 million in 2013, 2012 and 2011 respectively, for research and development. The principal focus of our research and development activities has been to improve processes and to develop new products that support the growth of our businesses. The spending on research and development was principally to develop new higher-margin application-specific products, including, among others, our 65nm process development for next generation programmable products, higher power PoE solutions, the continued roadmap development of our industry-leading timing & synchronization products, our silicon germanium (SiGe) RF power amplifier solutions for wireless LAN applications, and the ongoing development of gallium nitride (GaN) and silicon carbide (SiC) power management and RF solutions.

PATENTS, LICENSES, AND OTHER INTELLECTUAL PROPERTY RIGHTS

We have registered several of our trademarks with the U.S. Patent and Trademark Office and in foreign jurisdictions. We rely to some extent upon confidential trade secrets and patents to develop and maintain our competitive position. It is our policy to seek patent protection for significant inventions that may be patented, though we may elect, in appropriate cases, not to seek patent protection even for significant inventions if other protection, such as maintaining the invention as a trade secret, is considered more advantageous or cost-effective. We believe that patent and mask work protection could grow in significance but presently is of less significance in our business than experience, innovation, and management skill. No individual patent contributed significantly to our 2013, 2012 or 2011 net sales.

Due to the many technological developments and the technical complexity of the semiconductor industry, it is possible that certain of our designs or processes may involve infringement of patents or other intellectual property rights held by others. From time to time, we have received, and in the future may receive, notice of claims of infringement by our products on intellectual property rights of third parties. If any such infringements were alleged to exist, we might be obligated to seek a license from the holder of the rights and might have liability for past infringement. In the past, it has been common semiconductor industry practice for patent holders to offer licenses on reasonable terms and rates. Although in some situations, typically where the patent directly relates to a specific product or family of products, patent holders have refused to grant licenses. The practice of offering licenses appears to be generally continuing. However, no assurance can be given that we will be able to obtain licenses as needed in all cases or that the terms of any license that may be offered will be acceptable to us. In those circumstances where an acceptable license is not available, we would need either to change the process or product so that it no longer infringes or stop manufacturing the product or products involved in the infringement, which might be costly and could adversely affect our revenues and operating results.

Please see the information that is set forth under the subheading “Any failure by us to protect our proprietary technologies or maintain the right to use certain technologies may negatively affect our ability to compete,” within the section below entitled “ITEM 1A. RISK FACTORS.”

SALES TO THE U.S. GOVERNMENT

Approximately 31% of total net sales in 2013 were in the Defense & Security end market and sales in this end market highly correlate to customers whose principal sales are to the U.S. Government or to subcontractors whose material sales are to the U.S. Government. We, as a subcontractor, sell our products to higher-tier subcontractors or to prime contractors based upon purchase orders that usually do not contain all of the conditions included in the prime contract with the U.S. Government. However, these sales are usually subject to termination and/or price renegotiations by virtue of their reference to a U.S. Government prime contract. Therefore, we believe that all of our product sales that ultimately are sold to the U.S. Government may be subject to termination, at the convenience of the U.S. Government or to price renegotiations under the Renegotiation Act. In addition, the shutdown of non-essential U.S. Government services in October 2013 and any future government shutdowns may significantly increase the risk of contract terminations or renegotiations. At least one of our contracts has been terminated in the past due to the termination of the underlying government contract. There can be no assurance that we will not have contract termination or price renegotiation in the future, and any such termination or renegotiation could have a material adverse impact upon our revenues and results of operations.

COMPETITIVE CONDITIONS

The semiconductor industry, including the areas in which we do business, is highly competitive. We expect intensified competition from existing competitors and new entrants. Competition is based on price, product performance, product availability, quality, reliability and customer service. We compete in various markets with companies of various sizes, some of which are larger and have greater financial and other resources than we have, and thus may be better able to pursue acquisition candidates and to withstand adverse economic or market conditions. In addition, companies not currently in direct competition with us may introduce competing products in the future. Some of our current major competitors are Aeroflex Holding Corporation; Altera Corporation; Fairchild Semiconductor International, Inc.; Freescale Semiconductor, Inc.; Texas Instruments, Inc.; Integrated Device Technology, Inc.; International Rectifier Corp.; Linear Technology Corp.; M/A COM Technology Solutions Inc.; Maxim Integrated Products, Inc.; Micrel Incorporated; Monolithic Power Systems, Inc.; O2Micro International, Ltd.; Semtech Corp.; Silicon Laboratories, Inc.; Skyworks Solutions, Inc.; Supertex, Inc. and Xilinx, Inc. Some of our competitors in developing markets are Integrated Device Technology, Inc.; Semtech Corp.; Silicon Laboratories, Inc.; Skyworks Solutions, Inc. and Triquint Semiconductor, Inc. Several of these companies are larger than we are and have greater resources than we have and may therefore be better able than we are to penetrate new markets, pursue acquisition candidates, and withstand adverse economic or market conditions. We expect intensified competition from both these existing competitors and new entrants into our markets. To the extent we are not able to compete successfully in the future, our financial condition, operating results or cash flows could be harmed.

We have implemented a growth strategy through continuous innovation complemented by strategic acquisitions with the intent of increasing our technology footprint in customers’ end designs in high-value, high barrier-to-entry markets. This allows us to offer an increased value proposition, gather a larger portion of the bill of materials, and engage with customers as a strategic partner as opposed to a socket provider. We believe this strategy strengthens our position in the industry as it protects and grows our share within those markets with the highest barriers to entry.

SEASONALITY

Generally, we are affected by the seasonal trends of the semiconductor and related industries. The impacts of seasonality are to some extent dependent on product and market mix of products shipped. These impacts can change from time to time and are not predictable. Factors that increase seasonality include, for example, holiday work schedules during our first fiscal quarter that tend to limit production and holiday demand that tends to increase net sales in the Communications end market during our fiscal first and fourth quarters.

ENVIRONMENTAL REGULATIONS

To date, our compliance with federal, state and local laws or regulations that have been enacted to regulate the environment has not had a material adverse effect on our capital expenditures, earnings, or competitive or financial position.

Federal, state and local laws and regulations impose various restrictions and controls on the discharge of materials, chemicals and gases used in semiconductor manufacturing processes. In addition, under some laws and regulations, we could be held financially responsible for remedial measures if our properties are contaminated or if we send waste to a landfill or recycling facility that becomes contaminated, even if we did not cause the contamination. Also, we may be subject to common law claims if we release substances that damage or harm third parties. Further, future changes in environmental laws or regulations may require additional investments in capital equipment or the implementation of additional compliance programs in the future. Any failure to comply with environmental laws or regulations could subject us to serious liabilities and could have material adverse effects on our operating results and financial condition.

In the conduct of our manufacturing operations, we have handled and do handle materials that are considered hazardous, toxic or volatile under federal, state or local laws. The risk of accidental release of such materials cannot be completely eliminated. In addition, we operate or own facilities located on or near real property that was formerly owned and operated by others. These properties were used in ways that involved hazardous materials. Contaminants may migrate from or within or through property. These risks may give rise to claims. We may be financially responsible for third parties, who are responsible for contamination, if they do not have funds, or if they do not make funds available when needed, to pay remediation costs imposed under environmental laws and regulations.

In Broomfield, Colorado, the owner of a property located adjacent to a manufacturing facility owned by one of our subsidiaries, Microsemi Corp. - Colorado, had notified the subsidiary and other parties of a claim that contaminants migrated to his property, thereby diminishing its value. In August 1995, the subsidiary, together with Coors Porcelain Company, FMC Corporation and Siemens Microelectronics, Inc. (former owners of the manufacturing facility), agreed to settle the claim and to indemnify the owner of the adjacent property for remediation costs. Although tricholorethylene and other contaminants previously used by former owners at the facility are present in soil and groundwater on the subsidiary's property, we vigorously

contest any assertion that our subsidiary caused the contamination. In November 1998, we signed an agreement with the three former owners of this facility whereby they have 1) reimbursed us for $0.5 million of past costs, 2) assumed responsibility for 90% of all future clean-up costs, and 3) promised to indemnify and protect us against any and all third-party claims relating to the contamination of the facility. An Integrated Corrective Action Plan was submitted to the State of Colorado. Sampling and management plans were prepared for the Colorado Department of Public Health & Environment. State and local agencies in Colorado are reviewing current data and considering study and cleanup options. The most recent forecast estimated that the total project cost, up to the year 2020, would be approximately $5.3 million; accordingly, we recorded a one-time charge of $0.5 million for this project in 2003. There has not been any significant development since 2003.

EMPLOYEES

At the end of fiscal year 2013, we employed approximately 1,800 persons domestically and 1,300 persons at our international facilities. None of our employees are represented by a labor union; however, some employees in Europe are represented by an employee works council pursuant to local regulations. We have experienced no work stoppages and believe our employee relations are good.


ITEM 1A.	RISK FACTORS

Negative or uncertain worldwide economic conditions could prevent us from accurately forecasting demand for our products, which could adversely affect our operating results or market share.

Recent negative worldwide economic conditions and market instability have made it increasingly difficult for us, our customers and our suppliers to accurately forecast future product demand trends. If signs of improvement in the global economy do not progress as expected and global economic conditions worsen, our forecasts of product demand trends could prove to be incorrect and could cause us to produce excess products that can depress product prices, increase our inventory carrying costs and result in obsolete inventory. Alternatively, this forecasting difficulty could cause a shortage of products, or materials used in our products, that could result in an inability to satisfy demand for our products and a loss of market share.

Negative or uncertain worldwide economic conditions may adversely affect our business, financial condition, cash flow and results of operations.

Recent domestic and global economic conditions have presented unprecedented and challenging conditions reflecting continued concerns about the availability and cost of credit, downgrades and continued negative pressure on sovereign credit ratings, the mortgage market, declining real estate values, increased energy costs, decreased consumer confidence and spending and added concerns fueled by the federal government's interventions in the financial and credit markets. These conditions have contributed to instability in both the domestic and international capital and credit markets, potentially increased the cost of credit and diminished expectations for the global economy. In addition, these conditions make it extremely difficult for our customers to accurately forecast and plan future business activities and could cause businesses to slow spending on our products, which could cause our sales to decrease or result in an extension of our sales cycles. Due to these conditions, our customers may have difficulties obtaining capital at adequate or historical levels to finance their ongoing businesses and operations, which could impair their ability to make timely payments to us. If that were to occur, we may be required to increase our allowance for doubtful accounts and our days sales outstanding would be negatively impacted. We cannot predict the timing, strength or duration of any economic slowdown or subsequent economic recovery, worldwide or within our industry. If signs of improvement in the global economy do not progress as expected and economic conditions worsen, our business, financial condition, cash flows and results of operations will be adversely affected.

We may be unable to successfully implement our acquisitions strategy or integrate acquired companies and personnel with existing operations.

We have in the past acquired a number of businesses or companies, additional product lines and assets, and we may continue to expand and diversify our operations with additional acquisitions. We may be unable to identify or complete prospective acquisitions for many reasons, including competition from other companies in the semiconductor industry and high valuations of business candidates. In addition, applicable antitrust laws and other regulations may limit our ability to acquire targets or force us to divest an acquired business, such as occurred with our attempt to acquire SEMICOA. If we are unable to identify suitable targets or complete acquisitions, our growth prospects may suffer, and we may not be able to realize sufficient scale advantages to compete effectively in all markets. To the extent that we are successful in making acquisitions, if we are unsuccessful in integrating acquired companies or product lines with existing operations, or if integration is more difficult or more costly than anticipated, we may experience disruptions that could have a material adverse effect on our business, financial condition and results of operations. In addition, the market price of our common stock could be adversely affected if the effect of any acquisitions on the Microsemi consolidated group's financial results is dilutive or is below the market's or financial

analysts' expectations. Some of the risks that may affect our ability to integrate or realize any anticipated benefits from acquired companies, businesses or assets include those associated with:


•	unexpected losses of key employees or customers of the acquired company;


•	conforming the acquired company's standards, processes, procedures and controls with our operations;


•	coordinating new product and process development;


•	increasing complexity from combining recent acquisitions;


•	hiring additional management and other critical personnel;


•	increasing the scope, geographic diversity and complexity of our operations;


•	difficulties in consolidating facilities and transferring processes and know-how;


•	other difficulties in the assimilation of acquired operations, technologies or products;


•	diversion of management's attention from other business concerns; and


•	adverse effects on existing business relationships with customers.

In connection with acquisitions, we may:


•	use a significant portion of our available cash;


•	issue equity securities, which would dilute current stockholders' percentage ownership;


•	incur substantial debt;


•	incur or assume contingent liabilities, known or unknown, including potential lawsuits, infringement actions and similar liabilities;


•	incur impairment charges related to goodwill or other intangibles;


•	incur large, immediate accounting write-offs; and


•	face antitrust or other regulatory inquiries or actions.

There can be no assurance that the benefits of any acquisitions will outweigh the attendant costs, and if they do not, our results of operations and stock price may be adversely affected.

Reliance on government contracts for a significant portion of our sales could have a material adverse effect on results of operations.

A significant portion of our sales are or may be derived from customers whose principal sales are to the U.S. government. These sales are or may be derived from direct and indirect business with the U.S. Department of Defense and other U.S. government agencies. Future sales are subject to the uncertainties of governmental appropriations and national defense policies and priorities, including impacts of sequestration under the Budget Control Act of 2011, constraints of the budgetary process and timing and potential changes in these policies and priorities. Additionally, the long-term outlook for the fiscal position of the U.S. federal government is also uncertain, as illustrated by the recent budget negotiations and the shutdown of non-essential U.S. federal government services in October 2013.

We have experienced delays and reduction in appropriations on programs that include our products. Further delays, reductions in or terminations of government contracts or subcontracts, including those caused by any past or future shutdown of the U.S. federal government, could materially and adversely affect our operating results. While we generally function as a subcontractor, further changes in U.S. government procurement regulations and practices, particularly surrounding initiatives to reduce costs, may adversely impact the contracting environment and our operating results.

Generally, the U.S. government and its contractors and subcontractors may terminate their contracts with us at any time, with or without cause. We have in the past experienced the termination of a contract due to the termination of the underlying government contract. All government contracts are also subject to price renegotiation in accordance with the U.S. Government Renegotiation Act. By reference to such contracts, all of the purchase orders we receive that are related to government contracts

are subject to these possible events. In addition, the shutdown of non-essential U.S. government services in October 2013 and any future government shutdowns may significantly increase the risk of contract terminations or renegotiations, and any such termination or renegotiation could have a material adverse impact upon our revenues and results of operations.

In addition, we are required to maintain compliance with government regulations, particularly for our facilities and products that service the defense and security markets. Maintaining compliance with these regulations, including audit requirements of the U.S. government and our customers that are subject to these requirements, requires that we devote resources to matters that include training, personnel, information technology and facilities. Failure to maintain compliance may result in the loss of certifications, fines and penalties that may materially and adversely affect our operating results.

Microsemi's aggregate net sales to the Defense & Security end market represented approximately 31% of total net sales in 2013. From time to time, we have experienced declining security and defense-related sales, primarily as a result of contract award delays and reduced security and defense program funding. We may be unable to adequately forecast or respond to the timing of and changes to demand for security and defense-related products. In the past, defense-related spending on programs that we participate in has increased at a rate that has been slower than expected, been delayed or declined. Our prospects for additional defense and security related sales may be adversely affected in a material manner by numerous events or actions outside our control.

The concentration of the facilities that service the semiconductor industry, including facilities of current or potential vendors or customers, makes us more susceptible to events or disasters affecting the areas in which they are most concentrated.

Relevant portions of the semiconductor industry, and the facilities that serve or supply this industry, tend to be concentrated in certain areas of the world. Events such as natural disasters and related disruptions, epidemics and health advisories like those related to Sudden Acute Respiratory Syndrome, Avian Influenza or the H7N9 Virus, flooding, tsunamis, power outages and infrastructure disruptions, and terrorism, civil unrest and political instability in those areas, have from time to time in the past, and may again in the future, adversely affect the semiconductor industry. In particular, events such as these could adversely impact our ability to manufacture or deliver our products and result in increased costs and a loss of revenue. Similarly, a localized risk affecting our employees or the staff of our suppliers could impair the total volume of products that we are able to manufacture, which could adversely affect our results of operations and financial condition.

In the first quarter of fiscal year 2012, severe flooding in certain regions of Thailand forced a shutdown of our operations in two subcontracted facilities in Thailand. The two Thailand facilities together accounted for as much as 5% of our total quarterly revenues. In response to the impact of flooding at subcontractor facilities in Thailand, we implemented plans to move production to other facilities outside the affected area. Current production capabilities at these other facilities have compensated for the loss of production in the flooded facilities in Thailand and we believe that we recovered from this event as of the end of the second quarter of 2012. However, unforeseen impacts on our customers, suppliers or subcontractors as a result of the flooding in Thailand, or other natural disasters, could continue to affect our revenue, consolidated financial position, results of operations and cash flows.

We are dependent on third parties for key functions including foundries for wafer supplies, subcontractors for assembly, test and packaging services and vendors for logistics, and problems at these third parties could adversely affect our business and operating results.

Provisions in our credit facility and our current leverage could adversely affect our consolidated financial position and our ability to operate our business.

Our credit facility requires that we comply with financial and restrictive covenants. Although we are currently in compliance with these covenants, unexpected downturns in our business may trigger certain covenants that increase our cost of borrowing, decrease the amounts available under our credit facility, or both. The current amount outstanding on our credit facility exceeds our current cash and cash equivalents balance, and we may incur additional debt in the future. Some of the risks that are associated with our leverage include the following:


•	our ability to obtain additional financing in the future for acquisitions, capital expenditures, general corporate purposes or other purposes may be impaired;


•	our current credit facility only permits borrowing on variable rates of interest and increases in certain benchmark interest rates will increase the cost of borrowing;


•	leverage will increase our vulnerability to declining economic conditions, particularly if the decline is prolonged;


•	failure to comply with any of our debt covenants may result in an event of default which, if not cured or waived, could have a material adverse effect on us;


•	financial and restrictive covenants may adversely affect our ability to implement business plans, react to changes in economic conditions or benefit from changes in tax regulations;


•	debt service payments will continue to have a negative impact on our cash flows; and


•	prepayment terms may discourage us from refinancing our current credit agreement or reduce the benefit of lower interest rates.

We are subject to laws, regulations and similar requirements, changes to which may adversely affect our business and operations.

We are subject to laws, regulations and similar requirements that affect our business and operations, including, but not limited to, the areas of commerce, import and export control (especially related to products in our Defense & Security end market), financial disclosures, intellectual property, income and other taxes, anti-trust, anti-corruption, labor, environmental, health and safety. Our compliance in these areas may be costly, especially in areas where there are inconsistencies between the various jurisdictions in which we operate. While we have implemented policies and procedures to comply with laws and regulations, there can be no assurance that our employees, contractors, suppliers or agents will not violate such laws and regulations or our policies. Any such violation or alleged violation could materially and adversely affect our business. Any changes or potential changes to laws, regulations or similar requirements, or our ability to respond to these changes, may significantly increase our costs to maintain compliance or result in our decision to limit our business, products or jurisdictions in which we operate, any of which could materially and adversely affect our business and operations.

The Dodd-Frank Wall Street Reform and Consumer Protection Act includes provisions regarding certain minerals and metals, known as conflict minerals, mined from the Democratic Republic of Congo and adjoining countries. These provisions

require companies to undertake due diligence procedures and report on the use of conflict minerals in its products, including products manufactured by third parties. Compliance with these provisions will cause us to incur costs to certify that our supply chain is conflict free and we may face difficulties if our suppliers are unwilling or unable to verify the source of their materials. Our ability to source these minerals and metals may also be adversely impacted. In addition, our customers may require that we provide them with a certification and our inability to do so may disqualify us as a supplier.

Unanticipated changes in our tax provisions, or exposure to additional income tax liabilities or unfavorable results of tax examinations could affect our financial results.

We are subject to income taxes in the United States and numerous foreign jurisdictions. Our tax liabilities are affected by the amounts we record in intercompany transactions for inventory, services, licenses, funding and other items. We are subject to ongoing tax examinations in various jurisdictions. Tax authorities may disagree with our intercompany charges or other matters and assess additional taxes. Our application of transfer pricing has been the primary subject of the current examination of our U.S. federal income tax returns. We regularly assess the likely outcomes of examinations in order to determine the appropriateness of our tax provision. However, the actual outcomes of examinations could result in large and unexpected tax liabilities for past tax periods and have a material impact on our financial condition. In addition, our effective tax rate in the future could be adversely affected by changes in the mix of earnings in countries with differing statutory tax rates and benefits, changes in the valuation of deferred tax assets and liabilities, changes in tax laws, especially tax laws related to foreign operations, and the discovery of new information in the course of our tax return preparation process. Any of these changes could materially affect our operating results, cash flows and financial condition.

We hold cash and cash equivalents at various foreign subsidiaries that may not be readily available to meet domestic cash requirements.

Our various foreign subsidiaries hold cash and cash equivalents and as we intend to reinvest certain foreign earnings indefinitely these balances held outside the United States may not be readily available to meet our domestic cash requirements. We require a substantial amount of cash in the United States for operating requirements, purchases of property and equipment, debt service, and potentially for future acquisitions. If we are unable to meet our domestic cash requirements using domestic cash flows from operations, domestic cash and cash equivalents, or by settling loans with our foreign subsidiaries, it may be necessary for us to consider repatriation of earnings that we have designated as permanently reinvested. This may require us to record additional income tax expense and remit additional taxes, which could have a material effect on our results of operations, cash flows and financial condition.

Our operating results may fluctuate in future periods, which could cause our stock price to decline.

We have experienced, and expect to experience in future periods, fluctuations in net sales and operating results from period to period. Our projections and results may be subject to significant fluctuations as a result of a number of factors including:


•	the timing of orders from and shipment of products to major customers;


•	an unexpected reduction in sales to, or loss of, key customers;


•	our product mix;


•	changes in the prices of our products;


•	manufacturing delays or interruptions;


•	delays or failures in testing and processing products for defense, security and aerospace applications;


•	inventory obsolescence or write-downs;


•	restructuring charges;


•	variations in the cost of components for our products;


•	limited availability of components that we obtain from a single or a limited number of suppliers; and


•	seasonal and other fluctuations in demand for our products.

We have in the past closed, combined, sold or disposed of certain of our operations, have current plans to combine certain of our operations and may determine to do so in the future, which could reduce our sales volume and result in significant restructuring costs.

In September 2009, we approved consolidation plans that resulted in the closure of our manufacturing facility in Scottsdale, Arizona during the quarter ended April 3, 2011. Scottsdale represented approximately 1% of our annual net sales in fiscal year 2011 and occupied a 135,000 square foot leased facility. We face major technical challenges in regards to transferring component manufacturing between locations. Before a transfer of manufacturing, we must be finished qualifying the new facility appropriately with the U.S. government or certain customers. In addition, to mitigate the potential for manufacturing disruptions following a closure, we typically build inventory to support the transition process. While we plan generally to retain revenues and income of those operations by transferring the manufacturing elsewhere within Microsemi's subsidiaries, our plans may change at any time based on reassessment of the alternatives and consequences. While we hope to benefit overall from increased gross margins and increased capacity utilization rates at remaining operations, the remaining operations will need to bear the corporate administrative and overhead costs, which are charges to income that had been allocated to the discontinued business units. Moreover, delays in effecting our consolidations could result in changes in the timing of realized costs savings and in greater than anticipated costs incurred to achieve the hoped for longer-range savings.

We may make further specific determinations to consolidate, close, sell or divest of additional facilities, operations or product lines, which could be announced at any time. Possible adverse consequences from current and future consolidation or disposition activities may include a loss of revenues and various accounting charges such as for workforce reduction, including severance and other termination benefits and for excess facilities, including lease termination fees, future contractual commitments to pay lease charges, facility remediation costs and moving costs to remove property and equipment from facilities. We may also be adversely impacted from inventory buildup in preparation for the transition of manufacturing, disposition costs, impairments of goodwill, a possible immediate loss of revenues, and other items in addition to normal or attendant risks and uncertainties. We may be unsuccessful in any of our current or future efforts to consolidate our business into a smaller number of facilities. Our plans to minimize or eliminate any loss of revenues during consolidation may not be achieved.

We may not be able to develop new technologies and products to satisfy changes in customer demand or industry standards, and our competitors could develop products that decrease the demand for our products.

Rapidly changing technologies and industry standards, along with frequent new product introductions, characterize the semiconductor industry. Our financial performance depends, in part, on our ability to design, develop, manufacture, assemble, test, market and support new products and enhancements on a timely and cost-effective basis. If we are unable to continue to reduce package sizes, improve manufacturing yields and expand sales, we may not remain competitive. Our recent spending on research and development was principally to develop new higher-margin application-specific products, including, among others, our 65nm process development for next generation programmable products, higher power PoE solutions, the continued roadmap development of our industry-leading timing & synchronization products, our SiGe RF power amplifier solutions for wireless LAN applications, and the ongoing development of GaN and SiC power management and RF solutions. The competitiveness of designs that we have introduced, including power-over-ethernet, CCFL and LED drivers, class-D audio amplifiers, InGaP RF power amplifiers for wireless LAN applications, development and adoption of silicon carbide technology, ASICs, VDMOS products for high frequency communications and S-band products for RF applications, are subject to various risks and uncertainties that we are not able to control, including changes in customer demand and the introduction of new or superior technologies by others. Moreover, any failure by us in the future to develop new technologies or timely react to changes in existing technologies could materially delay our development of new products, which could result in product obsolescence, decreased revenues and a loss of our market share to our competitors. New technologies or products that we may develop may not lead to an incremental increase in revenues, and there is a risk that these new technologies or products will decrease the demand for our existing products and result in an offsetting reduction in revenues. In addition, products or technologies developed by others may render our products or technologies obsolete or non-competitive. A fundamental shift in technologies in our product markets could have a material adverse effect on our competitive position within the industry.

Additionally, our ability to compete within our industry will depend on our ability to identify and ensure compliance with industry standards that are constantly evolving. The emergence of new industry standards could render our products incompatible with products developed by major manufacturers. As a result, we could be required to invest significant time and effort and to incur significant expense to redesign our products to ensure compliance with relevant standards. If our products are not in compliance with prevailing industry standards, it could have a material adverse effect on our business operations and financial results.

We must commit resources to research and development, design, and production prior to receipt of purchase commitments and could lose some or all of the associated investment.

We sell products primarily pursuant to purchase orders for current delivery, rather than pursuant to long-term supply contracts. Many of these purchase orders may be revised or canceled without penalty. As a result, we must commit resources to the research, design and production of products without any advance purchase commitments from customers. Any inability to sell a product after we devote significant resources to it could have a material adverse effect on our business, financial condition, results of operations and cash flows.

International operations and sales expose us to material risks and may increase the volatility of our operating results.

Net sales from international markets represent a significant portion of total net sales and totaled 47% in 2013. These sales were principally to customers in Europe and Asia. Foreign sales are classified as shipments to foreign destinations. We maintain several international facilities or contracts with entities outside the United States, including Canada, China, France, India, Ireland, Israel, Japan, Korea, Malaysia, Macau, the Philippines, Taiwan, Thailand and the United Kingdom. There are risks inherent in doing business internationally, including:


•	legislative or regulatory requirements and potential changes in or interpretations of requirements in the United States and in the countries in which we manufacture or sell our products;


•	tax regulations and treaties and potential changes in regulations and treaties in the United States and in and between countries in which we manufacture or sell our products;


•	fluctuations in income tax expense and net income due to differing statutory tax rates in various domestic and international jurisdictions;


•	trade restrictions;


•	uncertain interpretations of and difficulties enforcing intellectual property laws;


•	local business and cultural factors that may differ from our domestic standards and practices, including business practices from which we are prohibited from engaging by the Foreign Corrupt Practices Act (the “FCPA”) and other anti-corruption laws and regulations;


•	availability of transportation services, including disruptions related to work stoppages, security incidents or natural events at manufacturing, shipping or receiving points or along transportation routes;


•	work stoppages or disruption of local labor supply;


•	communication interruptions;


•	economic and political instability, including the recent uncertainty in the global financial markets;


•	acts of war or terrorism, or health issues (such as Sudden Acute Respiratory Syndrome, Avian Influenza or the H7N9 Virus), which could disrupt our manufacturing and logistical activities;


•	compliance with and changes in import/export regulations;


•	changes in tariffs and freight rates;


•	difficulties in collecting receivables and enforcing contracts generally;


•	restrictions in the transfer or repatriation of funds; and


•	currency exchange rate fluctuations, devaluation of foreign currencies, hard currencies shortages and exchange rate fluctuations.

International sales of our products that service the defense and security markets are subject to U.S. and local government regulations and procurement policies and practices including regulations relating to import-export control. Violations of export control regulations could result in suspension of our ability to export our products. Depending on the scope of the suspension, this could have a material effect on our ability to perform certain international contracts. In addition, failure to maintain compliance with U.S. and foreign government regulations, including the FCPA and foreign anti-corruption measures, may result in fines and penalties that may materially and adversely affect our operating results.

If political, military, transportation, health or other issues in foreign countries result in cancellations of customer orders or contribute to a general decrease in economic activity or corporate spending, or directly impact Microsemi's marketing, manufacturing, financial and logistics functions, our consolidated results of operations and financial condition could be materially adversely affected. In addition, the laws of certain foreign countries may not protect our products, assets or intellectual property rights to the same extent as do U.S. laws. Therefore, the risk of piracy of our technology and products, which could result in a material adverse effect on our financial condition, operating results and cash flows, may be greater in those foreign countries.

There may be unanticipated costs associated with appropriately scaling our manufacturing capacity to meet expected changes in customer demand.

We may incur unanticipated costs as we scale our manufacturing capacity to meet expected changes in customer demand. During periods of anticipated increases in customer demand, we may determine that our business will require increased manufacturing capacity on our part and on the part of certain outside foundries, assembly shops, or testing facilities for some of our integrated circuit products or other products. Expansion activities are subject to a number of risks, including:


•	unavailability or late delivery of the advanced, and often customized, equipment used in the production of our specialized products;


•	availability of qualified manufacturing personnel;


•	delays in bringing new production equipment on-line;


•	delays in supplying satisfactory designs or products to our existing customers;


•	unforeseen environmental, engineering or manufacturing qualification problems relating to existing or new facilities; and


•	overexpansion may result in unfavorable manufacturing variances, restructuring costs and impairments.

These and other risks may affect the ultimate cost and timing of any expansion of our capacity.

Downturns in the highly cyclical semiconductor industry have in the past adversely affected our operating results, cash flows and the value of our business, and may continue to do so in the future.

The semiconductor industry is highly cyclical and is characterized by constant technological change, rapid product obsolescence and price erosion, short product life-cycles, consolidations of customers, and fluctuations in product supply and demand. During recent years we, as well as many others in our industry, have experienced significant declines in the pricing of, as well as demand for, products during the “down” portions of these cycles, which have sometimes been severe and prolonged. We have also noted consolidations of customers, particularly our distributors, which may adversely affect our pricing leverage or ability to maintain sufficient distributor channel inventory to meet end customer demand. In the future, these downturns may prove to be as, or possibly even more, severe than past ones. Our ability to sell our products depends, in part, on continued demand in each of our diverse end markets. Each of these end markets has, in the past, experienced reductions in demand, and current and future downturns in any of these markets may continue to adversely affect our revenues, operating results, cash flows and financial condition.

The semiconductor business is subject to downward price pressure.

The market for our products has been characterized by declining selling prices, and we anticipate that our average selling prices will decrease in future periods, although the timing and amount of these decreases cannot be predicted with any certainty. The pricing pressure in the semiconductor industry in past years has been due to a large number of factors, many of which were not easily foreseeable, such as the Asian currency crisis, industry-wide excess manufacturing capacity, weak economic growth, the slowdown in capital spending that followed the “dot-com” collapse, the reduction in capital spending by telecom companies and satellite companies, and the effects of the tragic events of terrorism on September 11, 2001. Similar to past years, recent unfavorable economic conditions have resulted in a tightening of the credit markets. If signs of improvement in the global economy do not progress as expected and global economic conditions worsen, we may experience a decline in our average selling prices. In addition, our competitors have in the past, and may again in the future, lower prices in order to increase their market share. Continued downward price pressure in the industry may reduce our operating results and harm our financial and competitive position.

The semiconductor industry is highly competitive.

The semiconductor industry, including the areas in which we do business, is highly competitive. We expect intensified competition from existing competitors and new entrants. Competition is based on price, product performance, product availability, quality, reliability and customer service. We compete in various markets with companies of various sizes, some of which are larger and have greater financial and other resources than we have, and thus may be better able to pursue acquisition candidates and to withstand adverse economic or market conditions. In addition, companies not currently in direct competition with us may introduce competing products in the future. Some of our current major competitors are Aeroflex Holding Corporation; Altera Corporation; Fairchild Semiconductor International, Inc.; Freescale Semiconductor, Inc.; Texas Instruments, Inc.; Integrated Device Technology, Inc.; International Rectifier Corp.; Linear Technology Corp.; M/A COM Technology Solutions Inc.; Maxim Integrated Products, Inc.; Micrel Incorporated; Monolithic Power Systems, Inc.; O2Micro International, Ltd.; Semtech Corp.; Silicon Laboratories, Inc.; Skyworks Solutions, Inc.; Supertex, Inc. and Xilinx, Inc. Some of our competitors in developing markets are Integrated Device Technology, Inc.; Semtech Corp.; Silicon Laboratories, Inc.; Skyworks Solutions, Inc. and Triquint Semiconductor, Inc. Several of these companies are larger than we are and have greater resources than we have and may therefore be better able than we are to penetrate new markets, pursue acquisition candidates, and withstand adverse economic or market conditions. We expect intensified competition from both of these existing competitors and new entrants into our markets. To the extent we are not able to compete successfully in the future, our financial condition, operating results or cash flows could be harmed.

Compound semiconductor products may not successfully compete with silicon-based products.

Our choice of technologies for development and future implementation may not reflect future market demand. The production of gallium arsenide (GaAs), indium gallium phosphide (InGaP), indium gallium arsenide phosphide (InGaAsP) SiGe or SiC integrated circuits is more costly than the production of silicon circuits, and we believe it will continue to be more costly in the future. The costs differ because of higher costs of raw materials, lower production yields and higher unit costs associated with lower production volumes. Silicon semiconductor technologies are widely used in process technologies for integrated circuits, and these technologies continue to improve in performance. As a result, we must offer compound semiconductor products that provide vastly superior performance to that of silicon for specific applications in order for our products to be competitive with silicon products. If we do not offer compound semiconductor products that provide sufficiently superior performance to offset the cost differential and otherwise successfully compete with silicon-based products, our revenues and operating results may be materially and adversely affected.

Production delays related to new compound semiconductors could adversely affect our future results.

We utilize process technology to manufacture compound semiconductors such as GaAs, InGaP, InGaAsP, SiGe and SiC primarily to manufacture semiconductor components. We are pursuing this development effort internally as well as with third party foundries. Our efforts sometimes may not result in commercially successful products. Certain competitors offer this capability and our customers may purchase our competitors' products instead of ours for this reason. In addition, the third party foundries that we use may delay delivery of, or even completely fail to deliver, technology and products to us. Our business and financial prospects could be materially and adversely affected by any failure by us to timely produce these products.

We may be unable to retain our customers due in part to our inability to fulfill our customer demand and other factors.

Our ability to fulfill our customers' demand for our products is and will continue to be dependent in part on our order volumes and long lead times with regards to our manufacturing and testing of certain high-reliability products. The lead time for manufacturing and testing of high-reliability products can be many months. In response to current demand, we have recently increased our capital expenditures for production equipment as well as increased expenses for personnel at certain manufacturing locations. We may have delays or other difficulties in regards to increasing our production and in hiring and retaining qualified personnel. In addition, we have raised prices on certain products, primarily in our Aerospace, Defense & Security and Industrial end markets. Manufacturing delays and price increases may result in our customers reducing their purchase levels with us and/or seeking alternative solutions to meet their demand. In addition, the current demand may not continue in the future. Decreased sales as a result of a loss of one or more significant customers could materially and adversely impact our business and results of operations.

Unfavorable or uncertain conditions in certain retail markets that our OEM customers address may cause fluctuations in our rate of revenue growth or financial results.

Some of the principal markets we serve include consumer markets, such as mobile/connectivity and notebooks, monitors and LCD televisions. If domestic and global economic conditions worsen, overall consumer spending may be reduced or shifted to products other than those made by our customers, which would adversely impact demand for products in these markets. Reduced sales by our customers in these end markets will adversely impact demand by our customers for our products and could also slow new product introductions by our customers and by us. Lower net sales of our products would have an adverse effect on our revenue, cash flow and results of operations.

Fluctuations in sales of high-reliability products for use in implantable defibrillators may adversely affect our financial results.

Although the market for implantable defibrillators is growing, customers in this market could reduce their reliance on outside suppliers. The implantable defibrillator market also fluctuates based on several other factors, such as product recalls and the need to secure regulatory approvals. Product recalls can, from time to time, accelerate sales to levels that cannot be sustained for long periods of time. The timing and qualification of new generations of products brought to market by OEMs can also result in fluctuations in order rates.

Variability of our manufacturing yields may affect our gross margins and profits.

Our manufacturing yields vary significantly among products, depending on the complexity of a particular product's design and our experience in manufacturing that type of product. We have in the past experienced difficulties in achieving planned yields, which have adversely affected our gross margins and profits.

The fabrication of semiconductor products is a highly complex and precise process. Problems in the fabrication process can cause a substantial percentage of wafers to be rejected or numerous circuits on each wafer to be non-functional, thereby reducing yields. These difficulties include:


•	defects in masks, which are used to transfer circuit patterns onto our wafers;


•	impurities in the materials used;


•	contamination of the manufacturing environment; and


•	equipment failure.

Because a large portion of our costs of manufacturing is relatively fixed and average selling prices for our products tend to decline over time, it is critical for us to improve the number of shippable circuits per wafer and increase the production volume of wafers in order to maintain and improve our results of operations. Yield decreases can result in substantially higher unit costs, which could materially and adversely affect our operating results and have done so in the past. Moreover, our process technologies have primarily utilized standard silicon semiconductor manufacturing equipment, and production yields of compound integrated circuits have been relatively low compared with silicon circuit devices. We may be unable to continue to improve yields in the future, and we may suffer periodic yield problems, particularly during the early production of new products or introduction of new process technologies. In either case, our results of operations could be materially and adversely affected.

Some of our facilities are located near major earthquake fault lines.

Our headquarters, our major operating facilities, and certain other critical business operations are located near known major earthquake fault lines. We presently do not have earthquake insurance. We could be materially and adversely affected in the event of a major earthquake.

Delays in beginning production, implementing production techniques, resolving problems associated with technical equipment malfunctions, or issues related to government or customer qualification of facilities could adversely affect our manufacturing efficiencies and our ability to realize cost savings.

Microsemi's consolidated manufacturing efficiency will be an important factor in our future profitability, and we may be unsuccessful in our efforts to maintain or increase our manufacturing efficiency. Our manufacturing processes, and those utilized by our third-party subcontractors, are highly complex, require advanced and costly equipment and are sometimes modified in an effort to improve yields and product performance. We have from time to time, experienced difficulty in transitioning manufacturing processes to different facilities or adopting new manufacturing processes. As a consequence, we

have at times experienced delays in product deliveries and reduced yields. Every silicon wafer fabrication facility utilizes very precise processing, and processing difficulties and reduced yields commonly occur, often as a result of contamination of the material. Reduced manufacturing yields can often result in manufacturing and shipping delays due to capacity constraints. Therefore, manufacturing problems can result in additional operating expenses and delayed or lost revenues. Microsemi may experience manufacturing problems in achieving acceptable yields or experience product delivery delays in the future as a result of, among other things, upgrading existing facilities, relocating processes to different facilities, or changing its process technologies, any of which could result in a loss of future revenues or an increase in manufacturing costs.

Interruptions, delays or cost increases affecting our materials, parts, equipment or subcontractors may impair our competitive position.

Our manufacturing operations, and the outside manufacturing operations that we use increasingly, in some instances, depend upon obtaining a governmental qualification of the manufacturing process, and in all instances, adequate supplies of materials including wafers, parts and equipment (including silicon, mold compounds and lead frames) on a timely basis from third parties. Some of the outside manufacturing operations we use are based in foreign countries. Our results of operations could be adversely affected if we are unable to obtain adequate supplies of materials, parts and equipment in a timely manner or if the costs of materials, parts or equipment increase significantly. From time to time, suppliers may extend lead times, limit supplies or increase prices due to capacity constraints or other factors. Although we generally use materials, parts and equipment available from multiple suppliers, we have a limited number of suppliers for some materials, parts and equipment. In addition, if signs of improvement in the global economy do not progress as expected and global economic conditions worsen, our suppliers may cease operations or be unable to obtain capital at adequate or historical levels to finance their ongoing businesses and operations, which could impair their ability to continue to supply us. If alternate suppliers for these materials, parts and equipment are not available, our operations could be interrupted, which would have a material adverse effect on our operating results, financial condition and cash flows.

Fixed costs may reduce operating results if our sales fall below expectations.

Our expense levels are based, in part, on our expectations for future sales. Many of our expenses, particularly those relating to capital equipment and manufacturing overhead, are relatively fixed. We might be unable to reduce spending quickly enough to compensate for reductions in sales. Accordingly, shortfalls in sales could materially and adversely affect our operating results. This challenge could be made even more difficult if lead times between orders and shipments are shortening.

Failure to manage consolidation of operations effectively could adversely affect our margins and earnings.

Our ability to successfully offer and sell our products requires effective planning and management processes. Our consolidations and realignments of operations, and expected future growth, may place a significant strain on our management systems and resources, including our financial and managerial controls, reporting systems, procedures and information technology. In addition, we will need to continue to train and manage our workforce worldwide. Any unmet challenges in that regard could negatively affect our results of operations.

Any failure by us to protect our proprietary technologies or maintain the right to use certain technologies may negatively affect our ability to compete.

We rely heavily on our proprietary technologies. Our future success and competitive position depend in part upon our ability to obtain or maintain protection of certain proprietary technologies used in our principal products. We do not have significant patent protection on many aspects of our technology. The protection of some of our technology as “trade secrets” will not necessarily protect us from all uses by other persons of our technology, or their use of technology that is similar or superior to that which is embodied in our trade secrets. In addition, others may be able to independently duplicate or exceed our technology in whole or in part. In the instances in which we hold patents or patent licenses, such as with respect to some circuit components for notebook computers and LCD TVs, any patents held by us may be challenged, invalidated or circumvented, or the rights granted under any patents may not provide us with competitive advantages. Patents often provide only narrow protection and require public disclosure of information that may otherwise be subject to trade secret protection. In addition, patents eventually expire and are not renewable.

Obtaining or protecting our proprietary rights may require us to defend claims of intellectual property infringement by our competitors. We could also become subject to lawsuits in which it is alleged that we or companies we have acquired have infringed or are infringing upon the intellectual property rights of others with or without our prior awareness of the existence of those third-party rights, if any. Litigation in connection with our intellectual property, whether instituted by us or others, could be very costly and distract management and other resources from our business. We are currently involved in certain patent litigation to protect our patents and patent rights, which could cause legal costs to increase above normal levels over the next

several years. It is not possible to estimate the exact amounts of these costs, but it is possible that these costs could have a negative effect on our future results.

Moreover, if any infringement, real or imagined, happens to exist, arise or is claimed in the future, we may be exposed to substantial liability for damages and may need to obtain licenses from the patent owners, discontinue or change our processes or products or expend significant resources to develop or acquire non-infringing technologies. We may not be successful in such efforts, or such licenses may not be available under reasonable terms. Any failure by us to develop or acquire non-infringing technologies or to obtain licenses on acceptable terms could have a material adverse effect on our operating results, financial condition and cash flows.

Our products may be found to be defective or hazardous and we may not have sufficient liability insurance.

There is at any time a risk that our products may be found to be defective or to contain, without the customer's knowledge, certain prohibited hazardous chemicals after we have already shipped the products in volume, perhaps requiring a product replacement or recall. We may be subject to product returns that could impose substantial costs and have a material and adverse effect on our business, financial condition and results of operations. Our aerospace, defense, and industrial businesses in particular expose us to potential liability risks that are inherent in the manufacturing and marketing of high-reliability electronic components for critical applications. Production of many of these products is sensitive to minute impurities, which can be introduced inadvertently in manufacturing. Any production mistake can result in large and unanticipated product returns, product liability and warranty liability. Environmental regulations have imposed on every major participant in the electronics industry a new burden of determining and tracking the presence and quantity of certain chemicals in the content of supplies we buy and add to our products for sale and to inform our customers about each of our finished goods' relevant chemical contents. The management and execution of this process is very challenging, and mistakes in this information gathering process could have a material adverse effect on our business.

We may be subject to product liability claims with respect to our products. Our product liability insurance coverage may be insufficient to pay all such claims. In addition, product liability insurance may become too costly for us to maintain or may become completely unavailable to us in the future. We may not have sufficient resources to satisfy any product liability claims not covered by insurance, which would materially and adversely affect our financial position.

Environmental liabilities could adversely impact our consolidated financial position.

Federal, state and local laws and regulations impose various restrictions and controls on the discharge of materials, chemicals and gases used in our semiconductor manufacturing processes or in our finished goods. Under recent environmental regulations, we are responsible for determining whether certain toxic metals or certain other toxic chemicals are present in any given component we purchase and in each given product we sell. These environmental regulations have required us to expend a portion of our resources and capital on relevant compliance programs. In addition, under other laws and regulations, we could be held financially responsible for remedial measures if our current or former properties are contaminated or if we send waste to a landfill or recycling facility that becomes contaminated, even if we did not cause the contamination. Also, we may be subject to additional common law claims if we release substances that damage or harm third parties. Further, future changes in environmental laws or regulations may require additional investments in capital equipment or the implementation of additional compliance programs in the future. Any failure to comply with existing or future environmental laws or regulations could subject us to significant liabilities and could have a material adverse effect on our operating results, cash flows and financial condition.

In the conduct of our manufacturing operations, we have handled and do handle materials that are considered hazardous, toxic or volatile under federal, state and local laws. The risk of accidental release of such materials cannot be completely eliminated. In addition, we operate or own facilities located on or near real property that was formerly owned and operated by others. These properties were used in ways that involved hazardous materials. Contaminants may migrate from, within or through any such property, which may give rise to claims against us. Third parties who are responsible for contamination may not have funds, or may not make funds available when needed, to pay remediation costs imposed upon us jointly with them under environmental laws and regulations.

In Broomfield, Colorado, the owner of a property located adjacent to a manufacturing facility owned by one of our subsidiaries, Microsemi Corp. - Colorado, had notified the subsidiary and other parties of a claim that contaminants migrated to his property, thereby diminishing its value. In August 1995, the subsidiary, together with Coors Porcelain Company, FMC Corporation and Siemens Microelectronics, Inc. (former owners of the manufacturing facility), agreed to settle the claim and to indemnify the owner of the adjacent property for remediation costs. Although TCE and other contaminants previously used by former owners at the facility are present in soil and groundwater on the subsidiary's property, we vigorously contest any assertion that our subsidiary caused the contamination. In November 1998, we signed an agreement with the three former owners of this facility whereby they have 1) reimbursed us for $0.5 million of past costs, 2) assumed responsibility for 90% of

all future clean-up costs, and 3) promised to indemnify and protect us against any and all third-party claims relating to the contamination of the facility. An Integrated Corrective Action Plan was submitted to the State of Colorado. Sampling and management plans were prepared for the Colorado Department of Public Health & Environment. State and local agencies in Colorado are reviewing current data and considering study and cleanup options. The most recent forecast estimated that the total project cost, up to the year 2020, would be approximately $5.3 million; accordingly, we recorded a one-time charge of $0.5 million for this project in 2003. There has not been any significant development since September 28, 2003.

Litigation could adversely impact our consolidated financial position.

We are and have been involved in various litigation matters, including from time to time, litigation relating to employment matters, commercial transactions, intellectual property matters, contracts, environmental matters and matters related to compliance with governmental regulations. Litigation is inherently uncertain and unpredictable. The potential risks and uncertainties include, but are not limited to, such factors as the costs and expenses of litigation and the time and attention required of management to attend to litigation. An unfavorable resolution of any particular legal claim or proceeding, and/or the costs and expenses incurred in connection with a legal claim or proceeding, could have a material adverse effect on our consolidated financial position or results of operations.

Our future success depends, in part, upon our ability to continue to attract and retain the services of our executive officers or other key management or technical personnel.

We could potentially lose the services of any of our senior management personnel at any time due to a variety of factors that could include, without limitation, death, incapacity, military service, personal issues, retirement, resignation or competing employers. Our ability to execute current plans could be adversely affected by such a loss. We may fail to attract and retain qualified technical, sales, marketing and managerial personnel required to continue to operate our business successfully. Personnel with the expertise necessary for our business are scarce and competition for personnel with proper skills is intense. Also, attrition in personnel can result from, among other things, changes related to acquisitions, retirement and disability. We may not be able to retain existing key technical, sales, marketing and managerial employees or be successful in attracting, developing or retaining other highly-qualified technical, sales, marketing and managerial personnel, particularly at such times in the future as we may need to fill a key position. If we are unable to continue to develop and retain existing executive officers or other key employees or are unsuccessful in attracting new highly-qualified employees, our business, financial condition and results of operations could be materially and adversely affected.

The volatility of our stock price could affect the value of an investment in our stock and our future financial position.

The market price of our stock has fluctuated widely. Between September 30, 2012 and September 29, 2013, the market sale price of our common stock ranged between a low of $17.12 and a high of $26.72. The historic market price of our common stock may not be indicative of future market prices. We may not be able to sustain or increase the value of our common stock. The trading price of our common stock may be influenced by factors beyond our control, such as the recent unprecedented volatility of the financial markets and the current uncertainty surrounding domestic and foreign economies. Declines in the market price of our stock could adversely affect our ability to retain personnel with stock incentives, to acquire businesses or assets in exchange for stock and/or to conduct future financing activities with or involving our common stock.

We may not make the sales that are suggested by our order rates, backlog or book-to-bill ratio, and our book-to-bill ratio may be affected by product mix.

Undue reliance should not be placed on our backlog or book-to-bill ratios or changes to these amounts. We determine bookings substantially based on orders that are scheduled for delivery within 12 months. However, lead times for the release of purchase orders depend, in part, upon the scheduling practices of individual customers, and delivery times of new or non-standard products can be affected by scheduling factors and other manufacturing considerations. The rate of booking new orders can vary significantly from month to month. Customers frequently change their delivery schedules or cancel orders. We have in the past experienced long lead times for some of our products, which may have therefore resulted in orders in backlog being duplicative of other orders in backlog, which would increase backlog without resulting in additional revenues. Because of long lead times in certain products, our book-to-bill ratio may not be an indication of sales in subsequent periods. Uncertain worldwide economic conditions and market instability have also resulted in hesitance of our customers to place orders with long delivery schedules, which contributes to limited visibility into our markets.

At times, our working capital levels have risen, which adversely affects cash flow.

At times, our working capital levels have risen and the increase has adversely affected cash flow. A factor contributing to the increase in our working capital has related to acquisitions with increases in accounts receivable and inventory generally

exceeding increases in accounts payable and accrued liabilities. Another factor resulting in an increase in working capital has been a buildup of inventory prior to the consolidation of our manufacturing operations. We built inventory cushions during the transition of manufacturing between facilities in order to maintain an uninterrupted supply of product. Obsolescence of any inventory has recently and could in the future result in adverse effects on our future results of operations and future revenue. In 2009, in addition to other inventory write-downs, we recorded inventory write-downs of $10.3 million for product lines that did not meet gross margin targets, products that are being migrated to newer generations, and products that service the large capital spending end markets for which demand has declined and $7.3 million for estimated inventory components that were not expected to be used by the closure date of our Scottsdale facility and that cannot be used by other manufacturing facilities. During the quarter ended April 3, 2011, we recorded a charge of $8.4 million for the write-off of bridging inventory and an additional $8.2 million for the write-off of medical inventory.

There may be some potential effects of system outages or data security breaches, which could adversely affect our operations, financial results or reputation.

We face risks from electrical or telecommunications outages, computer hacking or other general system failure. We rely heavily on our internal information and communications systems and on systems or support services from third parties to manage our operations efficiently and effectively. Any of these are subject to failure. System-wide or local failures that affect our information processing could have a material adverse effect on our business, financial condition, results of operations and cash flows. In addition, a system failure or data security breach could also result in the unintentional disclosure of confidential information about us, our customers or our employees, which could result in our incurring costs for remedial or preventative actions, damage our reputation with customers and reduce demand for our products and services. Further, insurance coverage does not generally protect from normal wear and tear, which can affect system performance. Any applicable insurance coverage for an occurrence could prove to be inadequate. Coverage may be or become unavailable or inapplicable to any risks then prevalent. We are upgrading and integrating, and have plans to upgrade and integrate further, our enterprise information systems, and these efforts may cause additional strains on personnel and system resources or may result in potential system outages.

Our accounting policies and estimates have a material effect on the financial results we report.

Critical accounting policies and estimates have a material effect on our calculations and estimations of amounts in our financial statements. Our operating results and balance sheets may be adversely affected either to the extent that actual results prove to be materially lower than previous accounting estimates or to the extent that accounting estimates are revised adversely. We base our critical accounting policies, including our policies regarding revenue recognition, reserves for returns, rebates, price protections, and bad debt and inventory valuation, on various estimates and subjective judgments that we may make from time to time. The judgments made can significantly affect net income and our balance sheets. We are required to make significant judgments concerning inventory, and whether it becomes obsolete or excess, and concerning impairments of long-lived assets and of goodwill. Our judgments, estimates and assumptions are subject to change at any time. In addition, our accounting policies may change at any time as a result of changes in generally accepted accounting principles as they apply to us or changes in other circumstances affecting us. Changes in accounting policy have affected and could further affect, in each case materially and adversely, our results of operations or financial position.

If, in the future, we conclude that our internal control over financial reporting is not effective, investors could lose confidence in the reliability of our financial statements, which could result in a decrease in the value of our common stock.

As directed by Section 404 of the Sarbanes-Oxley Act of 2002, the SEC adopted rules requiring public companies to include a report of management on the companies' internal control over financial reporting in their annual reports on Form 10-K, including an assessment by management of the effectiveness of the filing company's internal control over financial reporting. In addition, the independent registered public accounting firm auditing a public company's financial statements must attest to the effectiveness of the company's internal control over financial reporting. There is a risk that in the future we may identify internal control deficiencies that suggest that our controls are no longer effective. This could result in an adverse reaction in the financial markets due to a loss of confidence in the reliability of our financial statements, which could cause the market price of our common stock to decline and make it more difficult for us to finance our operations.

Our investments in securities subject us to principal, liquidity and counterparty risks that could adversely affect our financial results.

We invest cash balances primarily in money market funds. At times, we have also entered into interest rate swap and foreign currency forward contracts. While all of our investments to date are highly rated and we believe our counterparties to be highly rated, current credit market disruptions may adversely affect the value and liquidity of these investments and may affect the ability of our counterparties to fulfill their contractual obligations.

We may have increasing difficulty attracting and retaining qualified outside Board members.

The directors and management of publicly traded corporations are increasingly concerned with the extent of their personal exposure to lawsuits and shareholder claims, as well as governmental and creditor claims that may be made against them in connection with their positions with publicly-held companies. Outside directors are becoming increasingly concerned with the availability of directors' and officers' liability insurance to pay on a timely basis the costs incurred in defending shareholder claims. Directors' and officers' liability insurance is expensive and difficult to obtain. The SEC and the NASDAQ Stock Market have also imposed higher independence standards and certain special requirements on directors of public companies. Accordingly, it may become increasingly difficult to attract and retain qualified outside directors to serve on our Board.

Delaware law and our charter documents contain provisions that could discourage or prevent a potential takeover of Microsemi that might otherwise result in our stockholders receiving a premium over the market price for their shares.

Provisions of Delaware law and our certificate of incorporation and bylaws could make more difficult an acquisition of Microsemi by means of a tender offer, a proxy contest, or otherwise, and the removal of incumbent officers and directors.

These provisions include:


•	Section 203 of the Delaware General Corporation Law, which prohibits a merger with a 15%-or-greater stockholder, such as a party that has completed a successful tender offer, without board approval until three years after that party became a 15%-or-greater stockholder;


•	The authorization in the certificate of incorporation of undesignated preferred stock, which could be issued without stockholder approval in a manner designed to prevent or discourage a takeover or in a way that may dilute an investment in our common stock; and

•

Certain provisions of our charter documents, including provisions eliminating the ability of stockholders to call special meetings and limiting the ability of stockholders to raise matters at a meeting of stockholders without giving advance notice, may have the effect of delaying or preventing changes in control or management of Microsemi. In addition, our charter documents do not permit cumulative voting, which may make it more difficult for a third party to gain control of our Board of Directors.

ITEM 3.	LEGAL PROCEEDINGS

On December 8, 2010, Intellectual Ventures I LLC and Intellectual Ventures II LLC filed a complaint in the United States District Court for the District of Delaware against Altera Corporation, Microsemi, and Lattice Semiconductor Corporation. On February 15, 2011, the plaintiffs filed an amended complaint adding Xilinx, Inc. as a defendant. The complaint alleges, inter alia, that programmable logic devices manufactured and sold by our subsidiary Microsemi - SoC infringe United States Patent Numbers 5,687,325, 6,260,087 and 6,272,646 assigned to Intellectual Ventures II LLC, and seeks damages and other relief at law or in equity as the court deems appropriate. In January 2013, the parties settled this matter as it pertains to Microsemi and the action against us was dismissed by the court. The resolution of this matter did not have a material adverse effect on our financial position, results of operations or cash flows.

We are involved in pending litigation, administrative and similar matters arising out of the normal conduct of our business, including litigation relating to acquisitions, employment matters, commercial transactions, contracts, environmental matters and matters related to compliance with governmental regulations. The ultimate aggregate amount of monetary liability or financial impact with respect to these matters is subject to many uncertainties and is therefore not predictable with assurance. In the opinion of management, the final outcome of these matters, if they are adverse, will not have a material adverse effect on our financial position, results of operations or cash flows. However, there can be no assurance with respect to such result, and monetary liability, financial impact or other sanctions imposed on us from these matters could differ materially from those projected.

POSSIBLE VOLATILITY OF STOCK PRICES

The market prices of securities issued by technology companies, including ours, have been and will be volatile. The securities of many technology companies have experienced extreme price and volume fluctuations, which have often not necessarily been related to their respective operating performances. Quarter to quarter variations in operating results, changes in earnings estimates by analysts, announcements of technological innovations or new products, announcements of major contract awards, events involving other companies in or out of the industry, economic conditions, events involving war or terrorism, and other events or factors may have a significant impact (positive or negative) on the market price of our Common Stock.

ITEM 7.	MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This Annual Report on Form 10-K includes current beliefs, expectations and other forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from the results contemplated by these forward-looking statements due to certain factors, including those discussed in Part I, Item 1A, “Risk Factors” and elsewhere in this Annual Report on Form 10-K. This “Management's Discussion and Analysis of Financial Condition and Results of Operations” (“MD&A”) and the accompanying consolidated financial statements and notes thereto must be read in conjunction with the MD&A and the consolidated financial statements and notes thereto in its entirety.

Unless the context otherwise requires, the “Company,” “Microsemi,” “we,” “our,” “ours” and “us” refer to Microsemi Corporation and its consolidated subsidiaries.

OVERVIEW

The principal end markets that we serve include aerospace, communications, defense & security, and industrial. Today, Microsemi products are found in communications infrastructure systems, both wireless and wired LAN systems, pacemakers and defibrillators, missile systems, military and commercial satellites and aircrafts, oil field equipment and airport security systems.

Mission and Vision Statements

Vision: Leading-edge system solutions, solving the most difficult problems where performance matters, reliability is vital and security is non-negotiable.

Our growth strategy is dependent on our ability to successfully develop new technologies and products, and is complemented by our ability to implement our selective acquisitions strategy. New technologies or products that we may develop may not lead to an incremental increase in revenues, and there is a risk that these new technologies or products will decrease the demand for our existing products and result in an offsetting reduction in revenues. There can be no assurance that the benefits of any acquisition will outweigh the attendant costs, and if they do not, our results of operations and stock price may be adversely affected.

Net sales decreased $36.6 million or 4%, to $975.9 million in 2013 from $1.0 billion in 2012 and increased $176.6 million or 21%, from $835.9 million in 2011. For 2012 and 2011, we estimate that between 15% to 20% and 25% to 30%, respectively, of net sales were derived from acquisitions concluded in each such fiscal year and each end market benefited from products we added from recent acquisitions. Estimated sales by end markets are based on our understanding of end market uses of our products. Our analysis of sales by end markets may be found in the “Results of Operations” section below. We believe an estimated breakout of net sales by end markets for the last three fiscal years is approximately as follows (amounts in thousands):



	2013		2012		2011
Aerospace	$	187,006	$	212,293	$	212,127
Communications	278,126		311,952		148,792
Defense & Security	306,311		286,430		299,503
Industrial	204,501		201,820		175,432
Total	$	975,944	$	1,012,495	$	835,854

Gross profit increased $4.6 million between 2013 and 2012, to $557.2 million (57.1% of sales) for 2013 from $552.6 million (54.6% of sales) for 2012 and increased $111.5 million between 2012 and 2011, from $441.2 million (52.8% of sales) for 2011. Gross margin improvements resulted from integration and cost improvement activities at both acquired and existing locations. During 2012, we recorded $9.2 million of acquisition-related inventory charges related to manufacturing profit in acquired inventory. Further, we recorded $3.2 million from an inventory write-off related to flooding in Thailand, net of insurance recoveries. These charges did not recur in 2013. Gross margin for 2011 was favorably impacted by higher margin products related to Microsemi – SoC, cost optimization programs, transfer of manufacturing to lower cost and more efficient facilities (including the closure of our Scottsdale facility) and reductions in personnel. During 2011, we recorded a charge of $8.4 million for the write-off of bridging inventory that we intended to complete at other locations and $8.2 million for the write-off of medical inventory that did not meet our corporate gross margin targets. Also in 2011, we recorded a $5.6 million charge for Scottsdale remediation and fixed assets that we abandoned as part of our Scottsdale facility closure and acquisition-related inventory charges $5.9 million related to manufacturing profit in acquired inventory.

Uncertain macroeconomic conditions worldwide subject us to certain risks (see Part I, Item 1A, Risk Factors, “Negative or uncertain worldwide economic conditions may adversely affect our business, financial condition, cash flow and results of operations,” “The concentration of the facilities that service the semiconductor industry, including facilities of current or potential vendors or customers, makes us more susceptible to events or disasters affecting the areas in which they are most concentrated,” and “We may be unable to successfully implement our acquisitions strategy or integrate acquired companies and personnel with existing operations.”).

We closed our Scottsdale facility during the second quarter of 2011. We may make further specific determinations to consolidate, close, sell or divest additional facilities, operations or product lines, which could be announced at any time. Possible adverse consequences from current and future consolidation or disposition activities may include a loss of revenues and various accounting charges such as for workforce reduction, including severance and other termination benefits and for excess facilities, including lease termination fees, future contractual commitments to pay lease charges, facility remediation costs and moving costs to remove property and equipment from facilities. We may also be adversely impacted from inventory buildup in preparation for the transition of manufacturing, disposition costs, impairments of goodwill, a possible immediate loss of revenues, and other items in addition to normal or attendant risks and uncertainties. We may be unsuccessful in any of our current or future efforts to consolidate our business into a smaller number of facilities. Our plans to minimize or eliminate any loss of revenues during consolidation may not be achieved.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States that require us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and revenues and expenses during the periods reported. Actual results could differ from those estimates. Information with respect to our critical accounting policies that we believe could have the most significant effect on our reported results and require subjective or complex judgments is contained in Note 1 to these consolidated financial statements.

Revenue Recognition, Sales Returns and Allowances

4) collectability is reasonably assured. For substantially all sales, revenue is recognized, net of estimated returns and discounts, at the time the product is shipped.

We enter into distribution agreements that permit rights to limited stock rotations, returns, price protection, and volume purchase and other discounts. We provide an estimated allowance for these rights and record a corresponding reductions in revenue. Our estimated allowance is based on several factors including past history and notification from customers of pending activity. Actual activity under such rights have been within management’s expectations.

We also derive a portion of our revenue from fixed-price contracts. Revenue for these contracts is recorded under a percentage of completion method, which is based on the ratio of total costs incurred to date to estimated total costs at completion. Gross profit expected to be realized on fixed-price contracts is based on periodic estimates of total revenues and costs for each contract. Losses on contracts are accrued when estimated total costs exceed total revenues. Occasionally, we will enter into contracts on a cost plus fee basis. We recognize revenue based on reimbursements for actual expenses plus the contractually agreed upon fee with the customer.

Restructuring Charges

We recognize a liability for restructuring costs when the liability is incurred. The restructuring accruals are based upon management estimates at the time they are recorded and can change depending upon changes in facts and circumstances subsequent to the date the original liability is recorded. The main components of our restructuring charges are workforce reductions and elimination of excess facilities. Workforce-related charges are accrued when it is determined that a liability exists, which is generally when individuals have been notified of their expected termination dates and expected severance payments or when formal severance plans exist, when the severance payments are probable and reasonably estimable. The elimination of excess facilities results in charges for lease termination fees, future contractual commitments to pay lease charges net of estimated sublease income, facility remediation costs and moving costs to remove property and equipment from the facilities. We recognize charges for elimination of excess facilities when we have vacated the premises or ceased use of the facility.

Stock-Based Compensation

Compensation expense for stock options and stock appreciation rights was calculated based on the grant or assumption date using the Black-Scholes pricing model. All stock appreciation rights we have granted or assumed are stock-settled. Stock options and stock appreciation rights are granted at exercise prices equal to the closing price of our common stock on the date of grant. Assumed stock options and stock appreciation rights are granted at exercise prices determined in accordance with the acquisition agreement. Expected life was estimated based on historical exercise data that was stratified between members of the Board of Directors, executive employees and all other recipients. Expected volatility was estimated based on historical volatility using equally weighted daily price observations over a period approximately equal to the expected life of each option. The risk free interest rate is based on the implied yield currently available on U.S. Treasury securities with an equivalent remaining term. No dividends are expected to be paid.

Performance stock units granted in 2012 will vest based on the Company's growth in net sales and earnings per share (subject to certain adjustments) for 2012 and 2013 in comparison with the growth in net sales and adjusted earnings per share over the same period for a peer group selected by the Compensation Committee. For these performance stock units, 50% of each performance-based award opportunity will be subject to the net sales metric for the performance period and 50% will be subject to the earnings per share metric for the performance period.

Performance stock units granted in 2013 will vest based on the Company achieving net sales and earnings per share (subject to certain adjustments) levels for 2013, 2014 and 2015. For these performance stock units, 25% of each performance-based award opportunity will be subject to the net sales metric for the performance period and 75% will be subject to the earnings per share metric for the performance period.

Accounting For Income Taxes

We account for income taxes under the asset and liability method, whereby deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

We evaluate the need to establish a valuation allowance for deferred tax assets based upon the amount of existing temporary differences, the period in which they are expected to be recovered and expected levels of taxable income. A valuation allowance to reduce deferred tax assets is established when it is more likely than not that some or all of the deferred tax assets will not be realized. We recognize uncertain tax positions when they meet a more-likely-than-not threshold. We recognize potential accrued interest and penalties related to unrecognized tax benefits as income tax expense.

Segment Information

We use the management approach for segment disclosure, which designates the internal organization that is used by management for making operating decisions and assessing performance as the source of our reportable segments. We manage our business on the basis of one reportable segment, as a manufacturer of semiconductors in different geographic areas, including the United States, Europe and Asia.

Accounts Receivable and Allowance for Doubtful Accounts

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The accounts receivable amount shown in the balance sheet are trade accounts receivable balances at the respective dates, net of allowance for doubtful accounts. The allowance for doubtful accounts is our best estimate of the amount of probable credit losses in our existing accounts receivable. We determine the allowance based in part on our historical write-off experience and specific review of account balances due. Past due balances are reviewed individually for collectability. All other balances are reviewed on a pooled basis by type of receivable. Account balances are charged off against the allowance when we determine that it is probable the receivable will not be recovered. We review our allowance for doubtful accounts quarterly. We do not have any off-balance-sheet credit exposure related to our customers. To date, our allowance for doubtful accounts has generally been within management’s estimates.

Inventories

Inventories are stated at the lower of cost, as determined using the first-in, first-out (“FIFO”) method, or market. Costs include materials, labor and manufacturing overhead. We evaluate the carrying value of our inventories taking into account such factors as historical and anticipated future sales compared with quantities on hand and the price we expect to obtain for our products in their respective markets. We also evaluate the composition of our inventories to identify any slow-moving or obsolete products. Additionally, inventory write-downs are made based upon such judgments for any inventories that are identified as having a net realizable value less than their cost, which is further reduced by related selling expenses. The net realizable value of our inventories for ongoing operations has generally been within management’s estimates. We have recorded inventory write-downs for discontinued product lines that did not meet gross margin targets, products that are being migrated to newer generations, products that service the large capital spending end markets for which demand has declined, products related to facility closures and losses related to flooding of a facility in Thailand.

Fair Value of Financial Assets and Liabilities

Accounting Standards Codification (“ASC”) 825 permits entities to elect the fair value option for certain financial assets and financial liabilities. For financial assets or financial liabilities for which an entity elects the fair value option, ASC 825 requires that the entity record the financial asset or financial liability at fair value rather than at historical cost with changes in fair value recorded in the income statement. ASC 825-25 requires that upfront costs and fees related to items for which the fair value option is elected shall be recognized in earnings as incurred and not deferred. As further discussed in Note 8 of the notes to the consolidated financial statements, we elected the fair value option in accounting for the term loan balance outstanding as of October 2, 2011. Following the extinguishment of the term loan in conjunction with our acquisition of Zarlink, we did not elect the fair value option and are reporting new term loan balances subsequent to October 2, 2011, at par value.

Long-Lived Assets

We assess the impairment of long-lived assets whenever events or changes in circumstances indicate that their carrying value may not be recoverable from the undiscounted estimated future cash flows expected to result from their use. We are required to make judgments and assumptions in identifying those events or changes in circumstances that may trigger impairment. Some of the factors we consider include:


•	Significant decrease in the market value of an asset.


•	Significant changes in the extent or manner for which the asset is being used or in its physical condition including manufacturing plant closures.


•	A significant change, delay or departure in our business strategy related to the asset.


•	Significant negative changes in the business climate, industry or economic conditions.


•	Current period operating losses or negative cash flow combined with a history of similar losses or a forecast that indicates continuing losses associated with the use of an asset.

If events or circumstances indicate that the carrying amount of a long-lived asset or asset group may not be recoverable and the expected undiscounted future cash flows attributable to the asset group are less than the carrying value, an impairment loss equal to the excess of the carrying value of the assets within the asset group over their fair value is recorded. The appropriate asset group is determined based on the lowest level of largely independent cash inflows and outflows for the related assets. Depending on the nature of the primary assets in the asset group, fair value is estimated using one of several approaches including replacement cost, appraised values, market quotes or estimated expected future cash flows using a discount rate commensurate with the risk involved. During 2009, we recorded a held for sale impairment of $1.7 million related to the real estate and building for our closed manufacturing facility in Broomfield, Colorado and a held and used impairment of $4.5 million for the closure of our manufacturing facility in Scottsdale, Arizona to reflect our long-lived assets at their lower fair value. Future impairments may be required if we close other manufacturing sites.

Goodwill and Intangible Assets

We account for goodwill on an impairment-only approach and amortize intangible assets with definite useful lives over the benefit period, which approximates straight-line expense over the respective useful lives. We assess qualitative factors to determine whether it is more likely than not that an indefinite-lived intangible asset such as goodwill is impaired as the basis for determining whether a quantitative impairment test is required. We assess definite-lived intangible assets for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be fully recoverable. Whenever we determine that there has been an impairment of goodwill or other intangible assets with indefinite lives, we will record an impairment charge against earnings. We operate as one reporting unit and an impairment charge would equal the excess of the carrying value of goodwill in our one reporting unit over its then fair value. The identification of intangible assets and determination of the fair value and useful lives are subjective in nature and often involve the use of significant estimates and assumptions. The judgments made in determining the estimated useful lives assigned to each class of assets can significantly affect net income. We completed our most recent qualitative analysis during the fourth quarter of 2013 and noted no significant factors existed during the fiscal year to indicate that it was more likely than not that the fair value of the reporting unit is less than its carrying amount.

RESULTS OF OPERATIONS

Net sales decreased $36.6 million or 4%, to $975.9 million for 2013 from $1.0 billion for 2012. Net sales increased $176.6 million or 21%, from $835.9 million for 2011. For 2012 and 2011, we estimate that between 15% to 20% and 25% to 30%, respectively, of net sales were derived from acquisitions concluded in each such fiscal year and each end market benefited from products we added from recent acquisitions. Estimated sales by end markets are based on our understanding of end market uses of our products. An estimated breakout of net sales by end markets is approximately as follows (amounts in thousands):



	2013		2012		2011
Aerospace	$	187,006	$	212,293	$	212,127
Communications	278,126		311,952		148,792
Defense & Security	306,311		286,430		299,503
Industrial	204,501		201,820		175,432
Total	$	975,944	$	1,012,495	$	835,854

Net sales in the Aerospace end market decreased $25.3 million to $187.0 million in 2013 from $212.3 million in 2012 and increased $0.2 million between 2012 and 2011 from $212.1 million in 2011. While we believe that we are benefiting from significant content growth on newer aircrafts, net sales were impacted by irregular order rates that we attribute to OEMs and subcontractors filling their channels to prepare for production and then slowing as manufacturing begins. In addition, during the second quarter of 2013, sales of space level products were adversely impacted by longer lead times affecting the timing of sales; sales of space level products have recovered in subsequent quarters, which contributed to a sequential net sales increase in this end market for the fourth quarter of 2013. During 2012 and 2011, we noted an increase in robust demand and order rates for commercial aircraft at aircraft manufacturers and tier one suppliers, growing electronic content in current aircraft, refurbishment programs for older aircraft and demand for the high-reliability radar and avionics solutions we provide. This growth followed a period where this end market was negatively impacted by global economic conditions. Growth in 2012 was offset by a slowdown in satellite billings in the beginning of the year though we have experienced increases in recent satellite order activity, which we believe is a reflection of our product portfolio, especially in system-level products, power management, and programmable logic ICs. Generally space-related applications are in a less economically sensitive market, but due to higher average selling prices and our significant dollar content in satellite applications, this end market can fluctuate on a quarterly basis based on the timing of shipments.

Net sales in the Communications end market decreased $33.8 million to $278.1 million in 2013 from $312.0 million in 2012 and increased $163.2 million between 2012 and 2011 from $148.8 million in 2011. While this end market benefited from increased contributions of voice circuit and timing and synchronization products in 2013 and 2012, our overall Communications end market is sensitive to macroeconomic conditions and capital expenditure deployment, which resulted in a decline in net sales in 2013. During the first half of 2013, PoE, power management, RF and voice circuit products were especially impacted by macroeconomic factors, further impacting 2013 results. The increase in net sales during 2012 was due primarily to the contributions of voice circuit and timing and synchronization products of Microsemi - CMPG while net sales in 2011 benefited from our acquisition of Microsemi - SoC. Both 2012 and 2011 net sales also benefited from steady sales increases in our power management and conversion solutions. We expect to continue expanding our market opportunity in timing and synchronization products and believe we are well poised for growth, as a result of new product acceptance as well as expectations for an increase in telecommunications carrier spend on these products. We expect net sales in the Communications end market to benefit from market share gains and market expansion in PoE and network synchronization, with continued steady growth from our existing timing and synchronization products. While we expect unfavorable macroeconomic conditions to affect this end market in the upcoming quarter, we believe that the strength of our timing and synchronization and wireless products will result in steady sales growth in the near term.

Net sales in the Defense & Security end market increased $19.9 million to $306.3 million in 2013 from $286.4 million in 2012 and decreased $13.1 million between 2012 and 2011 from $299.5 million. Sales in 2013 and 2012 uncertainty surrounding the defense budget was reflected in cautious procurement plans of our customers. Sales for 2012 were also adversely impacted by the lack of a 2012 federal budget through the first quarter of 2012. While the uncertainty about the impact of sequestration impacted overall defense spending, this end market has grown steadily over the last year. We believe the most recent budget emphasizes command, control, communications, computers, intelligence, surveillance and reconnaissance and equates to growing electronic content. Further, sales in this end market benefited from contributions from the ramping of millimeter wave scan subsystems used in whole-body scanners, missile defense and military RF applications. We also believe that net sales benefited from increasing international defense sales, enabled in part by our security product offerings, and that Microsemi's dollar content in defense programs will increase as our products move up the value chain. We believe the Departments of Defense and Homeland Security's budgets for electronic content, an area of Microsemi focus, will continue to expand and contribute to growth in this end market. We believe that net sales have benefited from our industry leading technology breadth and total solutions approach and as a result, we are currently bidding for more potential dollar value than any time in our past. We recognize that the current uncertainty surrounding the U.S. federal budget and sequestration may result in short-term delays in defense programs but believe in our long term growth prospects for this end market.

Net sales in the Industrial end market increased $2.7 million to $204.5 million in 2013 from $201.8 million in 2012 and increased $26.4 million between 2012 and 2011 from $175.4 million. During 2013, bookings were steady for medical, semiconductor capital equipment, industrial lasers, MRI and other broadline industrial applications while bookings for solar

applications increased. The increase in 2012 was due primarily to the contributions of medical products of Microsemi - CMPG, though we noted growth in plasma cutting and welding applications where our high power proficiency differentiates our products. We also noted steady contributions from our products for industrial printing, rail transport and precision GPS products for surveying. Over the intermediate to longer term, we believe that our differentiated medical products and early design-in activity in industrial automation applications will result in growth for this end market.

An estimated breakout of net sales by originating geographic area for 2013, 2012 and 2011 is approximately as follows (amounts in thousands):



	2013		2012		2011
United States	$	514,632	$	501,257	$	452,802
Europe	142,343		165,942		186,505
Asia	292,589		320,430		181,440
Other	26,380		24,866		15,107
Total	$	975,944	$	1,012,495	$	835,854

Selling, general and administrative expenses decreased $9.9 million between 2013 and 2012 to $202.5 million for 2013 from $212.3 million in 2012 and increased $24.8 million between 2012 and 2011 from $187.5 million in 2011. While incremental costs from recent acquisitions contributed to increased SG&A expenses, increases were offset by cost control measures and a reduction in stock-based compensation expense. We also recorded acquisition related costs of $7.3 million in 2012 and $11.8 million in 2011 that were not incurred in 2013. In connection with the relocation of one of our facilities during 2012, we received cash consideration of $15.0 million and recorded this consideration in selling, general and administrative costs as an offset to incremental costs incurred for the relocation.

We continually update our estimates with respect to our performance stock units. Compared to the estimates used in 2012, our updated estimates had the impact of reducing stock-based compensation expense by $4.0 million for 2013 YTD.

Research and development expense increased $2.1 million between 2013 and 2012 to $170.6 million in 2013 from $168.5 million in 2012 and increased $54.4 million between 2012 and 2011 from $114.2 million in 2011. While incremental costs from recent acquisitions contributed to increased research and development expenses, increases were generally offset by cost control measures. The principal focus of our research and development activities has been to improve processes and to develop new products that support the growth of our businesses. The spending on research and development was principally to develop new higher-margin application-specific products, including, among others, our 65nm process development for next generation programmable products, higher power PoE solutions, the continued roadmap development of our industry-leading timing & synchronization products, our silicon germanium (SiGe) RF power amplifier solutions for wireless LAN applications, and the ongoing development of gallium nitride (GaN) and silicon carbide (SiC) power management and RF solutions.

Amortization of intangible assets decreased $19.9 million between 2013 and 2012 to $84.8 million in 2013 from $104.8 million 2012 and increased $42.3 million between 2012 and 2011 from $62.4 million in 2011. The decrease in expense in 2013 was primarily from the amortization of backlog related to Microsemi - CMPG that had an amortizable life of one year and the increase in 2012 was due primarily to our acquisition of Microsemi - CMPG. These amounts include amortization related to acquired completed technology of $39.0 million for 2013, $40.6 million for 2012 and $29.4 million for 2011. The increases in amortization expense in 2012 and 2011 reflect amounts related to recently completed acquisitions.

Restructuring charges amounted to $9.9 million in 2013 compared to $8.7 million in 2012 and $22.1 million in 2011. The variances relate to the timing and announcement of restructuring activities. In 2009, we approved consolidation plans that

resulted in the closure of our manufacturing facility in Scottsdale, Arizona (“Scottsdale”), which ceased production during the quarter ended April 3, 2011. The Scottsdale facility occupied a 135,000 square foot leased facility. Employee severance is expected to be paid through 2013. Facility termination costs relate primarily to remaining obligations under facility and equipment leases and are expected to be paid through 2016. The following table reflects the restructuring activities for the Scottsdale facility and the accrued liabilities in the consolidated balance sheets at the dates below (amounts in thousands):



	Employee Severance			Facility Termination Costs			Total
Balance at September 30, 2012	$	117		$	5,848		$	5,965
Reversal of prior provision	(117		)	—			(117		)
Cash expenditures	—			(1,341		)	(1,341		)
Balance at September 29, 2013	$	—		$	4,507		$	4,507

At September 30, 2012, we had recorded severance accruals of $2.3 million from reductions in force at our various facilities other than Scottsdale. We recorded additional provisions, primarily for severance and retention payments, totaling $10.0 million in 2013. Provisions for severance covered approximately 200 individuals in manufacturing, engineering and sales. Employee severance is expected to be paid within the next twelve months. Contract termination costs relate primarily to remaining obligations under facility leases and are expected to be paid through 2020. Other associated costs related primarily to relocation costs that we incurred for the consolidation of several facilities in Northern California. The following table reflects the related restructuring activities and the accrued liabilities in the consolidated balance sheets at the dates below (amounts in thousands):



	Employee Severance			Contract Termination Costs			Other Associated Costs			Total
Balance at September 30, 2012	$	2,122		$	190		$	—		$	2,312
Provisions	9,380			539			96			10,015
Cash expenditures	(9,479		)	(344		)	(96		)	(9,919		)
Other non-cash settlement	(197		)	(6		)	—			(203		)
Balance at September 29, 2013	$	1,826		$	379		$	—		$	2,205

Interest expense was $30.4 million in 2013, $39.9 million in 2012 and $16.7 million in 2011. Between 2013 and 2012, the decrease in interest expense was primarily due to a lower term loan balance of $676.0 million at the end of 2013 compared to $776.0 million at the end of 2012. The increase in interest expense between 2012 and 2011 was primarily due to a higher term loan balance, which was $372.2 million at the end of 2011.

Other expense, net, was $3.1 million in 2013 compared to $33.5 million in 2012 and $16.7 million in 2011. During the second quarter of 2013, we entered into Amendment No. 4 to our Credit Agreement dated as of November 2, 2010 with MSSF and the lenders referred to therein (as amended, the “Credit Agreement”), which among other things, reduced the interest rate on our term loan to 3.75%. We accounted for the fourth amendment as a debt modification with respect to amounts that remained in the syndicate and a debt extinguishment with respect to the $277.5 million that exited the syndicate and recorded debt extinguishment expense of $3.0 million. The amendment did not impact the net principal balance outstanding. In connection with the original Credit Agreement, in 2011, we entered into interest rate swap agreements for the purpose of minimizing the variability of cash flows in the interest rate payments of our variable rate borrowings. In connection with the acquisition of Zarlink, we entered into a foreign currency forward agreement during Q4 2011 to minimize our foreign currency risk associated with the transaction that we funded in Canadian Dollars. We reflected the change in fair value of our term loan balances, swaps and forward contract through other income or expense. We recorded income of $5.1 million during the first quarter of 2012 related to these adjustments. During the first quarter of 2012, we amended our credit facility and accounted for the amendment as a debt extinguishment. Accordingly, we recorded $34.0 million in debt extinguishment costs in other income (expense). During the second quarter of 2012, we further amended our credit facility and accounted for this amendment as a debt modification with respect to amounts that remained in the syndicate and a debt extinguishment with respect to amounts that exited the syndicate. As such, we immediately expensed $1.2 million in financing costs related to the debt extinguishment. Subsequent to the amendment in the first quarter of 2012, we did not elect the fair value option on our outstanding term loan balances. In 2011, we elected the fair value option in accounting for the term loan balance outstanding under our Credit Agreement and changes in fair value of the loan balances are reflected as adjustments to the income statement. In connection with the Credit Agreement, we entered into interest rate swap agreements for the purpose of minimizing the variability of cash flows in the interest rate payments of our variable rate borrowings. In connection with the acquisition of Zarlink, we entered

into a foreign currency forward agreement in the fourth quarter of 2011 to minimize our foreign currency risk associated with the transaction that we funded in Canadian Dollars (“CAD”). We reflect the change in fair value of our term loan balances, swaps and forward contract through other income or expense. We recorded expense of $3.3 million related to these adjustments. In addition, upon election of the fair value option, we were required to immediately expense up front debt issuance and refinancing costs that totaled $14.2 million in 2011. Finally, in 2011 we recorded a gain of $2.0 million related to the sale of a facility.

We recorded a provision for income taxes of $12.4 million on pretax income of $56.1 million in 2013 compared to a provision for income taxes of $15.0 million on pre-tax loss of $14.7 million in 2012. During 2013 and 2012, we generated tax expense of $12.4 million and $15.0 million, respectively, primarily due to the tax provision on profitable entities in foreign jurisdictions and U.S. tax provision relating to deferred tax liabilities that will not provide future sources of income to realize deferred tax assets. We had cumulative operating losses for the three years ended in 2013 for our U.S. operations and several foreign operations and accordingly, have provided a full valuation allowance on certain of our U.S. and foreign net deferred tax assets as we have determined that it is more likely than not that the tax benefits will not be realized in the future.

During 2013 we increased the valuation allowance by $13.9 million, which primarily related to deductions for intangible (non-goodwill) amortization. During 2012 we increased the valuation allowance by $194.7 million, which primarily related to the acquisition of Microsemi - CMPG during the quarter ended January 1, 2012, and the recording of the deferred tax assets related to the acquisition. During 2011 we released the remaining valuation allowance related to our Israel operation, based on evaluation of key positive and negative evidence including the history of substantial losses in past years but cumulative income for the past three year period, and the indefinite carryforward period for the Israeli net operating loss carryforwards which are the principal component of our deferred tax assets in Israel.

CAPITAL RESOURCES AND LIQUIDITY

We had $256.4 million and $204.3 million in cash and cash equivalents at September 29, 2013 and September 30, 2012, respectively. During 2013, we financed our operations with cash generated from operations. A significant portion of our cash and cash equivalents are domiciled in the United States and we believe that we will be able to meet our future capital and liquidity requirements without significant tax consequences.

Net cash provided by operating activities decreased $6.2 million to $165.0 million in 2013 from $171.2 million in 2012. During 2013, net cash provided by operating activities was reduced by restructuring activities resulting in payments of $11.3 million. During 2012, we made payments of $20.5 million in restructuring and severance payments related primarily to Microsemi - CMPG and $9.2 million in transaction related costs. During 2011, we issued $26.1 million in credits to Microsemi - SoC distributors, paid $17.2 million in acquisition related costs ($10.9 million was accrued in the fourth quarter of fiscal year 2010 or was a liability recorded by Microsemi - SoC at the time of acquisition) and paid $18.2 million in severance and retention bonuses, primarily for Microsemi - SoC.

A summary of net cash provided by operating activities in 2013, 2012 and 2011 is as follows (amounts in thousands):



	2013			2012			2011
Net income (loss)	$	43,674		$	(29,675	)	$	55,730
Depreciation and amortization	113,650			136,050			91,482

Net change in other long term assets and liabilities	(7		)	(5,184		)	(1,111		)
Net cash provided by operating activities	$	165,007		$	171,223		$	146,561

Accounts receivable increased $8.9 million to $162.1 million at September 29, 2013 from $153.2 million at September 30, 2012. The increase in accounts receivable was primarily due to decreased linearity in sales in the fourth quarter of 2013 as compared to the fourth quarter of 2012.

Inventories increased $2.9 million to $162.0 million at September 29, 2013 from $159.1 million at September 30, 2012.

Current liabilities decreased $23.2 million to $133.2 million at September 29, 2013 from $156.5 million at September 30, 2012. The decrease was due to payments of accrued bonus and profit sharing and the timing of vendor

payments, offset by the timing of pay periods relative to our fiscal quarter ends and an increase in deferred revenue related to contracts accounted for under the percentage of completion method.

Net cash used in investing activities was $37.3 million in 2013 compared to $625.9 million in 2012 and $460.5 million in 2011. Net cash used in investing activities in 2013 consisted of $37.3 million in purchases of property and equipment. Net cash used in investing activities in 2012 consisted of net cash consideration of $540.2 million and $44.0 million, respectively, for the acquisitions of Zarlink and the timing, synchronization and synthesis business of Maxim Integrated Products, Inc., $1.0 million capital contribution to an investment fund and $49.1 million in purchase of property and equipment, offset by $4.4 million in proceeds from the sale of an investment, $3.7 million for the settlement of foreign currency forward and $0.3 million in insurance proceeds related to the Thailand flooding. Net cash used in investing activities in 2011 primarily consisted of $436.8 million in net cash consideration for four acquisitions and purchases of property and equipment of $25.8 million, offset by $2.2 million in proceeds for the sale of assets.

Net cash provided by (used in) financing activities was $75.6 million in 2013, $392.4 million in 2012 and $380.6 million in 2011. Net cash provided by financing activities in 2013 primarily consisted of $25.0 million in net proceeds from stock awards, offset by principal prepayments of the credit facility of $100.0 million and $0.6 million in credit facility issuance and refinancing costs. Net cash provided by financing activities in 2012 primarily consisted of net borrowings of $403.8 million under our credit agreement and $30.4 million in net proceeds from stock awards, offset by $41.8 million in credit facility issuance and refinancing costs. Net cash provided by financing activities in 2011 consisted of net borrowings of $372.1 million under our credit agreement and $25.7 million related to proceeds from stock awards, offset by $17.2 million in credit facility issuance and refinancing costs.

During the quarter ended March 31, 2013, we entered into Amendment No. 4 to our Credit Agreement. The amendment extended the term loan maturity date, provided new pricing terms, including reducing the interest rate on our term loan to 3.75%, and modified certain financial covenant provisions such that they are not scheduled to be reported unless we have revolving or swingline loan balances outstanding at the end of a fiscal quarter. We accounted for the fourth amendment as a debt modification with respect to amounts that remained in the syndicate and a debt extinguishment with respect to the $277.5 million that exited the syndicate and recorded debt extinguishment expense of $3.0 million. The amendment did not impact the net principal balance outstanding. As of September 29, 2013, we had $676.0 million in term loan borrowings and no borrowings under the revolving credit facility.

Under the Credit Agreement, we may borrow under a Base Rate which approximates the prime rate or Eurodollar Rate which approximates LIBOR. In the case of term loans, the Eurodollar Rate will not be lower than 1.00%. The applicable interest rate margin per annum for each type of loan at September 29, 2013 is as follows:



	Base Rate	Eurodollar Rate
Revolving and swingline loans	3.50%	4.50%
Term loans	1.75%	2.75%

As of September 29, 2013, term loan borrowings were under the Eurodollar Rate and subject to an interest rate of 3.75%. Based on the current term loan balance outstanding, a 10 percent change in interest rates would result in a corresponding change to interest expense of $2.5 million. The fair value of our term loan balance was $674.3 million and we classify this valuation as a Level 2 fair value measurement.

The amended term loan facility matures in February 2020 and principal amortizes at $7.3 million per year. During the fiscal year ended September 29, 2013, we completed optional principal prepayments of $100.0 million. While there are currently no scheduled principal repayments until the maturity date, the Credit Agreement stipulates an annual payment of a percentage of Excess Cash Flow (“ECF”). The ECF percentage is between 0% and 50% depending on our consolidated leverage ratio as of the end of a fiscal year.

We currently pay an undrawn commitment fee of 3.75% on the unused portion of the revolving facility. If any letters of credit are issued, then we expect to pay a fronting fee equal to 0.25% per annum of the aggregate face amount of each letter of credit and a participation fee on all outstanding letters of credit at a per annum rate equal to the margin then in effect with respect to Eurodollar Rate-based loans on the face amount of such letter of credit.

The Credit Agreement includes financial covenants requiring a maximum leverage ratio and minimum fixed charge coverage ratio that are applicable only when revolving loans or swingline loans are outstanding at the end of a fiscal quarter and also contains other customary affirmative and negative covenants and events of default. We were in compliance with our covenants as of September 29, 2013.

Also on October 21, 2013, we entered into a commitment letter with MSSF pursuant to which MSSF has committed to provide a $150 million incremental term loan facility (the “Incremental Term Facility”) which was syndicated on November 1, 2013. The Incremental Term Facility is available to (i) finance the Tender Offer, (ii) repay any existing indebtedness of Symmetricom following the consummation of the merger, and (iii) pay fees and expenses related to the merger. Interest under the Incremental Term Facility is, at Microsemi’s option, Base Rate or LIBOR, plus a margin of 1.50% for Base Rate-based loans and 2.75% for LIBOR-based loans with a 0.75% LIBOR floor. The covenants under the Incremental Term Facility are consistent with those in our existing Credit Agreement.

Contractual Obligations

The following table summarizes our contractual payment obligations and commitments, excluding liability related to uncertain tax positions, at September 29, 2013 (amounts in thousands):



	Payments due by period
	Total		Less than 1 year		1-3 years		3-5 years		More than 5 years		Imputed Interest
Credit facility	$	676,000	$	—	$	—	$	—	$	676,000	$	—
Interest on credit facility	165,478		26,547		51,263		51,263		36,405		—
Commitment fee on credit facility	398		190		190		18		—		—
Interest rate swap payments	626		548		78		—		—		—
Capital leases	3,165		292		585		585		5,265		(3,562		)
Other long-term liabilities	42,251		755		17,365		726		23,405		—
Operating leases	108,146		19,884		32,160		25,349		30,753		—
Purchase obligations	50,641		32,787		17,708		146		—		—
Total	$	1,046,705	$	81,003	$	119,349	$	78,087	$	771,828	$	(3,562	)

As of September 29, 2013, we recorded $16.5 million in long-term liabilities for accrued taxes related to uncertain tax positions and are not able to reasonably estimate the timing of the long-term payments, or the amount by which our liability will increase or decrease over time; therefore, the liability related to uncertain tax positions has not been included in the contractual obligations table.

Payments of interest on our credit facility in the contractual obligations table assumes that we will make no further term loan principal payments until the maturity date and incur interest at a rate of 3.75% per annum. Payments of the commitment fee on credit facility assumes our revolving credit facility remains undrawn. Interest swap payments are based on the current interest rate on our term loan of 3.75% per annum.

Off-Balance Sheet Arrangements

As of September 29, 2013, we had no off-balance sheet arrangements that have, or are reasonably likely to have, a current or future material effect on our consolidated financial condition, results of operations, liquidity, capital expenditures or capital resources.

Recently Issued Accounting Standards

the presentation of reclassification adjustments out of accumulated other comprehensive income. ASU 2013-02 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2012. We are currently assessing the impact of ASU 2013-02 but do not expect this ASU to materially impact our consolidated financial position, results of operations or cash flows.

In December 2011, the FASB issued ASU No. 2011-11, the objective of which is to provide additional disclosures on the effect or potential effect of rights of setoff associated with an entity's recognized assets and recognized liabilities within the scope of the update. The update primarily impacts financial instruments and derivatives subject to a master netting arrangement or similar agreement. ASU No. 2011-11 is effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. We are currently evaluating the disclosures required under this ASU.

In July 2012, the FASB issued ASU No. 2012-02, the objective of which is to reduce the cost and complexity of performing an impairment test for indefinite-lived intangible assets by simplifying how an entity test those assets or impairment and to improve consistency in impairment testing guidance among long-lived asset categories. The update permits an entity to assess qualitative factors to determine whether it is more likely than not than an indefinite-lived intangible asset is impaired as the basis for determining whether a quantitative impairment test is required. ASU No. 2012-02 is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. Early adoption is permitted and our adoption of the provisions in this ASU did not result in a material impact on our consolidated financial position, results of operations or cash flows.

In February 2013, the FASB issued ASU No. 2013-04, the objective of which is to provide guidance for the recognition, measurement, and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date. The guidance in the update requires that these arrangements be recorded as the sum of the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and any additional amount the reporting entity expects to pay on behalf of its co-obligors. ASU 2013-04 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. We are currently assessing the impact of this ASU on our consolidated financial position and results of operations.

In July 2013, the FASB issued ASU No. 2013-11 which requires that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward, with certain exceptions. ASU 2013-11 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. We are currently assessing the impact of this ASU but adoption will only have the potential of affecting the presentation of unrecognized tax benefits and will no impact our consolidated financial position, results of operations or cash flows.


ITEM 7A.	QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to various forms of market risk, which is the potential loss arising from adverse changes in credit risk, foreign currency exchange rates, interest rates or the stock market.

We conduct a relatively small portion of our business in a number of foreign currencies, principally the European Union Euro, Canadian Dollar, British Pound, Israeli Shekel and Chinese RMB. We may receive some revenues in foreign currencies and purchase some inventory and services in foreign currencies. Accordingly, we are exposed to transaction gains and losses that could result from changes in exchange rates of foreign currencies relative to the U.S. dollar. Because transactions in foreign currencies have represented a relatively small portion of our business, foreign currency fluctuations have not had a material impact historically on our revenues or results of operations. However, there can be no assurance that future fluctuations in the value of foreign currencies will not have material adverse effects on our results of operations, cash flows or financial condition. We have not conducted a foreign currency hedging program thus far. We have considered and may continue to consider the adoption of a foreign currency hedging program.

Concentrations of credit risk exists because we rely on a significant portion of customers whose principal sales are to the U.S. Government. Approximately 31% of total net sales in 2013 were in the Defense & Security end market and sales in this end market highly correlate to customers whose principal sales are to the U.S. Government or to subcontractors whose material sales are to the U.S. Government. We, as a subcontractor, sell our products to higher-tier subcontractors or to prime contractors based upon purchase orders that usually do not contain all of the conditions included in the prime contract with the U.S. Government. However, these sales are usually subject to termination and/or price renegotiations by virtue of their reference to a U.S. Government prime contract. Therefore, we believe that all of our product sales that ultimately are sold to the U.S. Government may be subject to termination, at the convenience of the U.S. Government or to price renegotiations under the Renegotiation Act. In addition, the shutdown of non-essential U.S. Government services in October 2013 and any future government shutdowns may significantly increase the risk of contract terminations or renegotiations. At least one of our contracts was terminated in the past due to the termination of the underlying government contract. There can be no assurance

that we will not have contract termination or price renegotiation in the future, and any such termination or renegotiation could have a material adverse impact upon our revenues and results of operations.

We had one customer that was a distributor of our products, primarily servicing our Defense & Security and Aerospace end markets, that accounted for approximately 20% of net sales in 2012, and any disruption with this distributor could have a material adverse effect on our business, financial condition and results of operations.

In addition, net sales from international markets represent a significant portion of total net sales. Our net sales to international customers represented approximately 47% for 2013, 50% for 2012 and 46% for 2011. These sales were principally to customers in Europe and Asia. We maintain reserves for potential credit losses and such losses have been within management’s expectations.



	Base Rate	Eurodollar Rate
Revolving and swingline loans	3.50%	4.50%
Term loans	1.75%	2.75%

The amended term loan facility matures in February 2020 and principal amortizes at $7.3 million per year. During the fiscal year ended September 29, 2013, we completed optional principal prepayments of $100.0 million. While there are currently no scheduled principal repayments until the maturity date, the Credit Agreement stipulates an annual payment of a percentage of ECF. The ECF percentage is between 0% and 50% depending on our consolidated leverage ratio as of the end of a fiscal year.

In connection with the original Credit Agreement in November 2010, we entered into interest rate swap agreements for the purpose of minimizing the variability of cash flows in the interest rate payments of our variable rate borrowings. The cash flows received under the interest rate swap agreements are expected to offset the change in cash flows associated with LIBOR rate borrowings between the effective and maturity dates of the swaps. Our two swap agreements have notional amounts, fixed rates and expiration dates as follows: $121.0 million at 1.83% expiring January 2014 and $24.0 million at 2.21% expiring January 2015. We classify our interest rate swap balances as Level 2 fair value measurements. We determined the fair value of our interest rate swap agreements based on mid-market valuations reported to us by the counterparty to the swap agreements. Related to these interest rate swap agreements, we recorded a current liability of $0.3 million and a long-term liability of $0.4 million as of September 29, 2013 and a long-term liability of $1.9 million as of September 30, 2012. We reflect the change in fair value of the swaps through other income (expense), net and recorded income of $1.3 million in 2013 and income of $0.9 million in 2012.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and

Stockholders of Microsemi Corporation:

In our opinion, the consolidated financial statements listed in the accompanying index appearing under Item 8(1) present fairly, in all material respects, the financial position of Microsemi Corporation and its subsidiaries at September 29, 2013 and September 30, 2012 and the results of their operations and their cash flows for each of the three years in the period ended September 29, 2013 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule listed in the accompanying index appearing under Item 8(2) presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of September 29, 2013, based on criteria established in Internal Control – Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for these financial statements and financial statement schedule, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report to Stockholders on Internal Control over Financial Reporting. Our responsibility is to express opinions on these financial statements, on the financial statement schedule, and on the Company’s internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.	DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Description of Business

We are a leading designer, manufacturer and marketer of high-performance analog and mixed-signal semiconductor solutions differentiated by power, security, reliability and performance. Our semiconductors manage and control or regulate power, protect against transient voltage spikes and transmit, receive and amplify signals. We offer one of the industry's most comprehensive portfolios of semiconductor technology. Our products include high-performance, high-reliability radio frequency (RF) and power components, analog and RF integrated circuits (ICs), standard and customizable system-on-chip solutions (SoCs/cSoCs), and mixed-signal and radiation-tolerant field programmable gate arrays (FPGAs). We also offer subsystems and modules that include application-specific power modules and Power-over-Ethernet (PoE) midspans.

Our products include discrete and integrated component, module, and subsystem solutions that enhance customer designs by improving performance, reliability and power consumption, reducing size or protecting circuits. The principal end markets that we serve include Communications, Defense & Security, Aerospace and Industrial.

Fiscal Year

We report results of operations on the basis of fifty-two and fifty-three week periods. The fiscal year ended on September 29, 2013, September 30, 2012, and October 2, 2011 consisted of fifty-two weeks. In referencing a year, we are referring to the fiscal year ended on the Sunday generally closest to September 30.

Principles of Consolidation and Presentation of Financial Information

The consolidated financial statements include the accounts of Microsemi and our subsidiaries. All intercompany transactions and balances have been eliminated.

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the respective reporting periods. Actual results could differ from those estimates.

Reclassifications

Certain prior year amounts have been reclassified to conform to current year presentation.

Cash and Cash Equivalents

We consider all short-term, highly liquid investments with maturities of three months or less at date of acquisition to be cash equivalents.

Accounts receivable and allowance for doubtful accounts

Inventories

Fair Value of Financial Assets and Liabilities

Accounting Standards Codification (“ASC”) 825 permits entities to elect the fair value option for certain financial assets and financial liabilities. For financial assets or financial liabilities for which an entity elects the fair value option, ASC 825 requires that the entity record the financial asset or financial liability at fair value rather than at historical cost with changes in fair value recorded in the income statement. ASC 825-25 requires that upfront costs and fees related to items for which the fair value option is elected shall be recognized in earnings as incurred and not deferred. As further discussed in Note 8, we elected the fair value option in accounting for the term loan balance outstanding as of October 2, 2011. Following the extinguishment of the term loan in conjunction with our acquisition of Zarlink, we did not elect the fair value option and are reporting new term loan balances subsequent to October 2, 2011, at par value.

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC 820 establishes a hierarchy for ranking the quality and reliability of the information used to determine fair values and includes the following classifications:

Level 1: Quoted market prices in active markets for identical assets or liabilities.

Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data.

Level 3: Unobservable inputs that are not corroborated by market data.

The following financial assets and liabilities were measured at fair value on a recurring basis using the type of inputs shown (amounts in thousands):



	Fair Value Measurements Using:
	Total		Level 1 Inputs		Level 2 Inputs		Level 3 Inputs

Cash and cash equivalents	$	204,335	$	204,335	$	—	$	—
Pension plan assets	5,382		—		—		5,382
Interest rate swap liabilities	$	1,950	$	—	$	1,950	$	—

Cash and cash equivalents	$	256,433	$	256,433	$	—	—
Pension plan assets	$	5,558	$	—	$	—	$	5,558
Interest rate swap liabilities	$	643	$	—	$	643	$	—

There were no transfers of financial assets or liabilities between the classifications during 2013 or 2012.

Property and Equipment

Property and equipment are stated at lower of cost or realizable values. Depreciation is computed on the straight-line method over the estimated useful lives of the assets. Leasehold improvements are amortized over the shorter of the lease terms or the estimated useful lives. Maintenance and repairs are charged to expense as incurred and the costs of additions and betterments that increase the useful lives of the assets are capitalized.

Long-Lived Assets


•	Significant decrease in the market value of an asset.


•	Significant changes in the extent or manner for which the asset is being used or in its physical condition including manufacturing plant closures.


•	A significant change, delay or departure in our business strategy related to the asset.


•	Significant negative changes in the business climate, industry or economic conditions.


•	Current period operating losses or negative cash flow combined with a history of similar losses or a forecast that indicates continuing losses associated with the use of an asset.

Goodwill and Intangible Assets

Revenue Recognition, Sales Returns and Allowances

We primarily recognize revenue from customers, including distributors, when title and risk of loss have passed to the customer provided that: 1) evidence of an arrangement exists; 2) delivery has occurred; 3) the fee is fixed or determinable; and 4) collectability is reasonably assured. For substantially all sales, revenue is recognized at the time the product is shipped.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Research and Development

We expense the cost of research and development as incurred. Research and development expenses principally comprise payroll and related costs, supplies, and the cost of prototypes.

Restructuring Charges

Stock-Based Compensation

Compensation expense for our performance stock units is based upon our estimate of performance relative to a peer group for the 2012 grant and our expected performance over the performance period for the 2013 grant. The maximum percentage for a particular metric is 200% of the “target” number of units subject to the award related to that metric. For performance stock units granted in 2013, the maximum percentage is further adjusted by the Company's total shareholder return relative to a peer group selected by the Compensation Committee, up to a maximum of 125%. We continually update our estimates with respect to our performance stock units and compared to the estimates used prior to 2013, our updated estimates had the impact of reducing stock-based compensation expense by $4.0 million for 2013.

Accounting For Income Taxes

MICROSEMI CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

allowance to reduce deferred tax assets is established when it is more likely than not that some or all of the deferred tax assets will not be realized. We recognize uncertain tax positions when they meet a more-likely-than-not threshold. We recognize potential accrued interest and penalties related to unrecognized tax benefits as income tax expense.

Segment Information

Foreign Currency

All of our significant subsidiaries outside the United States use the United States Dollar (“USD”) as their functional currency. We have one subsidiary in China that uses the Chinese RMB as its functional currency. For subsidiaries that use USD as the functional currency, assets and liabilities are remeasured to USD at the exchange rate in effect at the balance sheet date except for non-monetary assets and capital accounts which are measured at historical rates; revenues, expenses, gains and losses are remeasured at rates of exchange that approximate the rates in effect at the transaction date. For subsidiaries that use the local currency as the functional currency, all assets and liabilities are remeasured to USD using exchange rates in effect at the end of the period. Resulting translation gains or losses are recognized as a component of other comprehensive income. We also conduct a relatively small portion of our business in a number of foreign currencies, principally the European Union Euro, Canadian Dollar, British Pound, Israeli Shekel and Chinese RMB.

Earnings Per Share

Basic earnings per share have been computed based upon the weighted-average number of common shares outstanding during the respective periods. Diluted earnings per share have been computed, when the result is dilutive, using the treasury stock method for stock awards outstanding during the respective periods. Earnings per share for 2013, 2012 and 2011 were calculated as follows (amounts in thousands, except per share data):



	Fiscal Years
	2013		2012			2011
BASIC
Net income (loss)	$	43,674	$	(29,675	)	$	55,730
Weighted-average common shares outstanding	89,508		85,837			83,916
Basic earnings (loss) per share	$	0.49	$	(0.35	)	$	0.66
DILUTED
Net income (loss)	$	43,674	$	(29,675	)	$	55,730
Weighted-average common shares outstanding for basic	89,508		85,837			83,916
Dilutive effect of stock awards	1,820		—			1,831

Diluted earnings (loss) per share	$	0.48	$	(0.35	)	$	0.65

For 2013, 2012 and 2011, 1.8 million, 5.1 million and 7.3 million awards, respectively, were excluded in the computation of diluted EPS as these stock awards would have been anti-dilutive.

MICROSEMI CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Concentration of Credit Risk and International Sales

Concentrations of credit risk exist because we rely on a significant portion of customers whose principal sales are to the U.S. Government. Approximately 31% of total net sales in 2013 were in the Defense & Security end market, with a very significant amount of these sales to customers whose principal sales are to the U.S. Government or to subcontractors whose material sales are to the U.S. Government. We, as a subcontractor, sell our products to higher-tier subcontractors or to prime contractors based upon purchase orders that usually do not contain all of the conditions included in the prime contract with the U.S. Government. However, these sales are usually subject to termination and/or price renegotiations by virtue of their reference to a U.S. Government prime contract. Therefore, we believe that all of our product sales that ultimately are sold to the U.S. Government may be subject to termination, at the convenience of the U.S. Government or to price renegotiations under the Renegotiation Act. In addition, the shutdown of non-essential U.S. Government services in October 2013 and any future government shutdowns may significantly increase the risk of contract terminations or renegotiations. At least one of our contracts has been terminated in the past due to the termination of the underlying government contract. There can be no assurance that we will not have contract termination or price renegotiation in the future, and any such termination or renegotiation could have a material adverse impact upon our revenues and results of operations.

Recently Issued Accounting Standards

In June 2011, the Financial Accounting Standard Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2011-05, that updates the presentation of comprehensive income such that an entity has the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. ASU No. 2011-05 is effective for public entities for fiscal years, and interim periods within those years, beginning after December 15, 2011 (the second quarter of our fiscal year 2012). These updates only affect the presentation of comprehensive income and did not materially impact our consolidated financial position, results of operations or cash flows. In February 2013, the FASB issued ASU 2013-02 related to the presentation of reclassification adjustments out of accumulated other comprehensive income. ASU 2013-02 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2012. We are currently assessing the impact of ASU 2013-02 but do not expect this ASU to materially impact our consolidated financial position, results of operations or cash flows.

periods within those years, beginning after December 15, 2013. We are currently assessing the impact of this ASU but adoption will only have the potential of affecting the presentation of unrecognized tax benefits and will no impact our consolidated financial position, results of operations or cash flows.


2.	ACQUISITIONS

During 2011, we acquired Actel Corporation (“Actel”), a leading supplier of low-power FPGAs, mixed-signal FPGAs, and system-critical FPGAs. We sometimes refer to this division herein as Microsemi - SoC. We also acquired AML Communications, Inc., a designer, manufacturer, and marketer of microelectronic assemblies for the defense industry, Asic Advantage, Inc. (“Asic Advantage”), a fabless semiconductor company that designs and manufactures a broad portfolio of high-performance, high-voltage and radiation-hardened mixed-signal integrated circuit solutions for the aerospace, automotive, communications, industrial and medical markets and substantially all the assets of Brijot Imaging Systems, Inc. (“Brijot”) and its passive millimeter wave imaging solutions technology. Payments for these acquisitions, net of cash acquired was $436.8 million.

During 2012, we acquired Zarlink Semiconductor, Inc. (“Zarlink”) for its world-leading, mixed-signal chip technologies for a broad range of communication and medical applications. We also acquired the timing, synchronization and synthesis business of Maxim Integrated Products, Inc. and integrated the operations of this business with Zarlink. Payments for these acquisitions, net of cash acquired was $585.2 million.

Generally, the allocation of purchase prices results in an allocation to goodwill. Depending on the structure of a particular acquisition, goodwill and identifiable intangible assets may not be deductible for tax purposes. We determined that goodwill related to to our acquisitions were not deductible with the exception of goodwill related to the acquisitions of the assets of the Timing, Synchronization and Synthesis Business of Maxim Integrated Products, Inc. and assets of Brijot Imaging Systems, Inc.

Supplemental pro forma data (unaudited)

The following supplemental pro forma data summarizes the results of operations for 2012 and 2011, as if all acquisitions during these years were completed as of the first day of the fiscal year immediately preceding the acquisition. The supplemental pro forma information presented is for illustrative purposes only and is not necessarily indicative of the financial position or results of operations that would have been realized if the transactions had been completed on the dates indicated, nor is it indicative of future operating results or financial position. Net sales and earnings for the acquisitions on a standalone basis since their acquisition dates are impracticable to determine, as on the acquisition date, we implemented a plan developed prior to the completion of the acquisition and began to immediately integrate these acquisitions into existing operations, engineering groups, sales distribution networks and management structure. The pro forma adjustments are based upon currently available information and certain assumptions that we believe are reasonable under the circumstances.

The supplemental pro forma data reports actual operating results, adjusted to include the pro forma effect of, among others, the impact in cost of goods sold from manufacturing profit in acquired inventory, amortization expense of identified intangible assets, timing of the impact of restructuring expenses, timing of credit facility issuance costs, foregone interest income, incremental interest expense and the related tax effect of these items. Supplemental pro forma earnings for 2012 were adjusted to exclude $9.2 million in cost of goods sold from manufacturing profit in acquired inventory, $7.3 million in acquisition costs and $34.0 million in credit facility refinancing costs associated with the Zarlink financing. Supplemental pro forma earnings for 2011 were adjusted to include the above noted items from 2012 and exclude $5.5 million in cost of goods sold from manufacturing profit in acquired inventory, $6.3 million in acquisition costs, $14.2 million in credit facility issuance costs and $5.0 million in non-cash benefits from valuation allowance releases. Supplemental pro forma earnings for 2010 were adjusted to include the above noted items excluded from 2011. Supplemental pro forma data does not adjust the timing of the refinancing completed in the quarter ended April 1, 2012. Supplemental pro forma data for the fiscal years in the period ended September 29, 2013 is as follows (amounts in thousands, except per share data) (unaudited):

	$	12,389	$	14,950		$	(33,681	)

We have federal and state net operating losses (“NOLs”) of approximately $256.4 million and $297.8 million, respectively, that begin expiring in 2021 and 2014, respectively. Of the total NOL carryforward, $19.9 million related to the excess tax benefit from employee stock compensation and stockholders' equity will increase by $19.9 million if and when such excess tax benefits are ultimately realized. We have foreign NOLs of approximately $250.3 million that carry forward indefinitely. We have federal and state research and experimentation credits of approximately $28.2 million and $44.4 million, respectively. We have foreign research and experimentation credits of approximately $81.8 million and incentive deductions of approximately $72.7 million. We have federal foreign tax credits of approximately $2.8 million. We have federal and state enterprise zone credits, state investment tax credits, and alternative minimum tax credits totaling $2.4 million that carry forward indefinitely. The utilization of NOLs and credits acquired through an acquisition may be subject to limitations due to change in control.

No provision has been made for future income taxes on undistributed earnings of U.S. and foreign operations (except for insignificant jurisdictions) since they have been indefinitely reinvested in these operations. Determination of the amount of unrecognized deferred tax liability for temporary differences related to these undistributed earnings is not practicable, as such liability is dependent upon a number of factors, including foreign tax credit position that would exist at the time any remittance would occur. At the end of fiscal years 2013 and 2012, these undistributed earnings aggregated approximately $357.4 million and $294.7 million, respectively.

A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (amounts in thousands):



	September 29, 2013			September 30, 2012			October 2, 2011
Beginning gross unrecognized tax benefits	$	58,016		$	32,370		$	21,719

We recognize interest and penalties accrued related to unrecognized tax benefits in tax expense. During the years ended September 29, 2013, September 30, 2012, and October 2, 2011, we recognized approximately $0.0 million, $2.0 million, and $0.7 million, respectively, in interest and penalties. The cumulative interest and penalties at September 29, 2013, September 30, 2012, and October 2, 2011 were $5.9 million, $6.0 million, and $4.2 million, respectively.

Unrecognized tax benefits of $58.9 million (including interest) at September 29, 2013 would impact the effective tax rate if recognized after the valuation allowance has been released. We anticipate a decrease in gross unrecognized tax benefits of approximately $4.2 million within the next twelve months based on federal, state, and foreign expirations in various jurisdictions.

We file U.S. federal, state, and foreign income tax returns in jurisdictions with varying statutes of limitations. Fiscal years 2007 to 2013 generally remain subject to examination by federal and most state tax authorities. In significant foreign jurisdictions, the 2009 to 2013 tax years generally remain subject to examination by tax authorities. We establish liabilities for possible assessments by tax authorities resulting from known tax exposures including, but not limited to, international tax issues and certain tax credits. We are currently undergoing an Internal Revenue Service examination as well as certain state examinations. There have been no significant proposed adjustments to date. As of September 29, 2013, the IRS has raised questions primarily related to transfer pricing. Management believes that the Company's position is appropriate and that an adequate provision has been made for any adjustments that may result from tax examinations. However, the outcome of tax audits cannot be predicted with certainty. If any issues addressed in the Company's tax audits are resolved in a manner not consistent with management's expectations, the Company would be required to adjust its provision for income tax in the period such resolution occurs. While the Company believes its reported results are accurate, any significant adjustments could have a material adverse effect on the Company's results of operations, cash flows and financial position if not resolved within expectations.


8.	CREDIT AGREEMENT AND RELATED INSTRUMENTS

Credit Agreement

We are a party to a senior secured credit facility with Morgan Stanley Senior Funding, Inc. (“MSSF”) consisting of a term loan facility and a $50.0 million revolving credit facility. As of September 29, 2013, we had $676.0 million in term loan borrowings and no borrowings under the revolving credit facility. We can also request the establishment of one or more swingline loans and/or revolving credit facilities with commitments in an aggregate amount not to exceed $200.0 million.

During the quarter ended March 31, 2013, we entered into Amendment No. 4 to our Credit Agreement dated as of November 2, 2010 with MSSF and the lenders referred to therein (as amended, the “Credit Agreement”). The amendment extended the term loan maturity date, provided new pricing terms, including reducing the interest rate on our term loan to 3.75%, and modified certain financial covenant provisions such that they are not scheduled to be reported unless we have revolving or swingline loan balances outstanding at the end of a fiscal quarter. We accounted for the fourth amendment as a debt modification with respect to amounts that remained in the syndicate and a debt extinguishment with respect to the $277.5 million that exited the syndicate and recorded debt extinguishment expense of $3.0 million. The amendment did not impact the net principal balance outstanding.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)



	Base Rate	Eurodollar Rate
Revolving and swingline loans	3.50%	4.50%
Term loans	1.75%	2.75%

As of September 29, 2013, term loan borrowings were under the Eurodollar Rate and subject to an interest rate of 3.75%. The fair value of our term loan balance was $674.3 million and we classify this valuation as a Level 2 fair value measurement.

Interest Rate Swap Agreements

Fair Value Option

We elected the fair value option in accounting for the term loan balance outstanding as of October 2, 2011 and determined the fair value to be $361.0 million compared to a par value of $372.2 million. We did not elect the fair value option subsequent to entering into Amendment No. 2 to the Credit Agreement and recorded an extinguishment expense of $11.2 million in other income (expense), net during 2012.

Foreign Currency Forward

In connection with the acquisition of Zarlink, we entered into a foreign currency forward agreement in the fourth quarter of 2011 to minimize our foreign currency risk associated with the transaction that we funded in Canadian Dollars (“CAD”). We agreed to purchase CAD 623.0 million for $608.2 million that settled in October 2011. We classified interest rate forward balances as Level 1 fair value measurements where there are quoted prices in active markets for identical instruments. We determined the fair value of our foreign currency forward agreement based on a corresponding quote from the counterparty to the forward transaction. As the foreign currency forward contract did not qualify for hedge accounting, we reflected the change in fair value of the swap through other income (expense), net. At October 2, 2011, we recorded a current liability and corresponding expense of $11.7 million for the change in fair value. During the quarter ended January 1, 2012, we recorded income of $15.4 million related to the settlement of this forward. As our only foreign currency forward agreement settled in the quarter ended January 1, 2012, we did not record a fair value adjustment subsequent to the quarter ended January 1, 2012.

10.	STOCK-BASED COMPENSATION

Stock Based Compensation

In January 2012, our stockholders approved an amendment to the Microsemi Corporation 2008 Performance Incentive Plan (the “2008 Plan”). The amendment 1) increased the share limit by an additional 14.5 million share-units so that the amended aggregate share-unit limit for the 2008 Plan is 28.5 million share-units; 2) extended the plan term to December 5, 2021; 3) increased the number of shares counted against the share-unit limit for every one share issued in connection with a full-value award to 2.41; 4) terminated the evergreen provision in the original plan; and 5) extended the Performance-Based Award feature through the first annual meeting of stockholders that occurs in calendar year 2017. Awards authorized by the 2008 Plan include options, stock appreciation rights, restricted stock, stock bonuses, stock units, performance share awards, and other cash- or share-based awards. The shares issued under the 2008 Plan may be newly issued or shares held by the Company as treasury stock. The maximum term of a stock option grant or a stock appreciation right granted under the 2008 Plan is 6 years.

Stock-based compensation expense was $35.2 million in 2013, $36.7 million in 2012 and $28.5 million in 2011. At September 29, 2013, unamortized compensation expense related to unvested stock awards was $40.9 million. The weighted average period over which compensation expense related to these grants will be recognized is 1.3 years.

Remaining share-units available for grant, assuming issuance of performance units at target, at September 29, 2013, September 30, 2012 and October 2, 2011 under the 2008 Plan were 12.2 million, 16.0 million and 6.4 million, respectively.

Performance Units

Compensation expense is based upon either our estimate of performance relative to a peer group for the 2012 grant and our expected performance over the performance period for the 2013 grant. The maximum percentage for a particular metric is 200% of the “target” number of units subject to the award related to that metric. For performance stock units granted in 2013, the maximum percentage is further adjusted by the Company's total shareholder return relative to a peer group selected by the Compensation Committee, up to a maximum of 125%.

11.	EMPLOYEE BENEFIT PLANS

We sponsor 401(k) savings plans whereby participating employees may elect to contribute up to 50% of their eligible wages up to the statutory contribution limit. Employees 50 years of age and older may contribute a further 75% of their eligible wages up to the statutory contribution limit. We suspended the employer match to this plan during 2009. In 2012, we reinstated the employer match and also made a non-elective employer contribution. During 2013, employer contributions were $3.9 million.

In certain entities outside the United States, we provide defined-benefit and defined contribution plans, many in accordance with local regulations. We typically deposit employer contributions with third party trustees, insurance trust funds, or government-managed accounts.

We assumed a pension plan in Germany related to our acquisition of Microsemi - CMPG in 2012 that covers employees with over ten years of active service and provides benefits based on length of service and final pensionable earnings. There are no segregated pension fund assets under this plan. The pension liability is insured and we have pledged the insurance contracts to the pensioners. Accordingly, the contracts are now considered to be a plan asset. As the plan assets are insurance contracts, the Company does not control the investment strategy and thus cannot influence the return on investments. The insurance payments are guaranteed by the insurer and should the insurer default on its obligation, the security fund for insurance companies in Germany would assume the contracts. As of September 29, 2013, the fair value of plan assets was $5.6 million and benefit obligations were $7.5 million. During 2012, we recorded an unrealized actuarial loss on pension benefits of $1.2 million in other comprehensive income due to a reduction in the discount rate assumption used to determine benefit obligations from 4.0% to 3.2% and a reduction in the expected rate of return on plan assets from 4.8% to 4.0%. There are no employer contributions expected in the next twelve months.


12.	COMMITMENTS AND CONTINGENCIES

Operating Leases

We occupy premises and lease equipment under operating lease agreements expiring through 2029. The aggregate undiscounted future minimum rental payments under these leases are as follows (amounts in thousands):



2014		2015		2016		2017		2018		Thereafter
$	19,884	$	16,950	$	15,210	$	13,718	$	11,631	$	30,753

Lease expense charged to income was $20.2 million in 2013, $21.4 million in 2012 and $13.6 million in 2011.

Contingencies

In Broomfield, Colorado, the owner of a property located adjacent to a manufacturing facility owned by one of our subsidiaries, Microsemi Corp. – Colorado had notified the subsidiary and other parties of a claim that contaminants migrated to his property, thereby diminishing its value. In August 1995, the subsidiary, together with Coors Porcelain Company, FMC Corporation and Siemens Microelectronics, Inc. (former owners of the manufacturing facility), agreed to settle the claim and to indemnify the owner of the adjacent property for remediation costs. Although tricholorethylene and other contaminants previously used by former owners at the facility are present in soil and groundwater on the subsidiary’s property, we vigorously contest any assertion that our subsidiary caused the contamination. In November 1998, we signed an agreement with the three former owners of this facility whereby they have 1) reimbursed us for $0.5 million of past costs, 2) assumed responsibility for 90% of all future clean-up costs, and 3) promised to indemnify and protect us against any and all third-party claims relating to the contamination of the facility. An Integrated Corrective Action Plan was submitted to the State of Colorado. Sampling and management plans were prepared for the Colorado Department of Public Health & Environment. State and local agencies in Colorado are reviewing current data and considering study and cleanup options. The most recent forecast estimated that the total project cost, up to the year 2020, would be approximately $5.3 million; accordingly, we recorded a one-time charge of $0.5 million for this project in 2003. There has not been any significant development since September 28, 2003.

We are generally self-insured for losses and liabilities related to workers’ compensation and employer’s liability insurance. Accrued workers’ compensation liability was $1.5 million and $1.4 million at September 29, 2013 and September 30, 2012, respectively. Our self-insurance accruals are based on estimates and, while we believe that the amounts accrued are adequate, the ultimate claims may be in excess of the amounts provided.

In January 2013, the parties settled this matter as it pertains to Microsemi and the action against us was dismissed by the court. The resolution of this matter did not have a material adverse effect on our financial position, results of operations or cash flows.


13.	RESTRUCTURING CHARGES AND SEVERANCE CHARGES

In 2009, we approved consolidation plans that resulted in the closure of our manufacturing facility in Scottsdale, Arizona (“Scottsdale”), which ceased production during the quarter ended April 3, 2011. The Scottsdale facility occupied a 135,000 square foot leased facility. Employee severance is expected to be paid through 2013. Facility termination costs relate primarily to remaining obligations under facility and equipment leases and are expected to be paid through 2016. The following table reflects the restructuring activities for the Scottsdale facility and the accrued liabilities in the consolidated balance sheets at the dates below (amounts in thousands):

At September 30, 2012, we had recorded severance accruals of $2.3 million from reductions in force at our various facilities other than Scottsdale. We recorded additional provisions, primarily related to activities at Microsemi - CMPG, for severance and retention payments totaling $10.0 million in 2013. Provisions for severance covered approximately 200 individuals in manufacturing, engineering and sales. Employee severance is expected to be paid within the next twelve months. Contract termination costs relate primarily to remaining obligations under facility leases and are expected to be paid through 2020. Other associated costs related primarily to relocation costs that we incurred for the consolidation of several facilities in Northern California. The following table reflects the related restructuring activities and the accrued liabilities in the consolidated balance sheets at the dates below (amounts in thousands):

ITEM 9.	CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE.

ITEM 9A.	CONTROLS AND PROCEDURES.

(a) Evaluation of disclosure controls and procedures.

As of September 29, 2013, under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, the Company carried out an evaluation of the effectiveness of the design and operation of the Company’s disclosure controls and procedures as defined in Exchange Act Rules 13a-15(e) and 15d-15(e). These disclosure controls and procedures are designed to ensure that the information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified by the SEC’s rules and forms, and that the information is accumulated and communicated to the Company’s management, including the Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Based upon their evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective as of September 29, 2013.

(b) Changes in internal control over financial reporting.

There have been no changes in the Company’s internal control over financial reporting during the fiscal quarter ended September 29, 2013 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Management is responsible for establishing and maintaining adequate internal control over financial reporting. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risks that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate.

Under the supervision and with the participation of management, including the Company’s Chief Executive Officer and Chief Financial Officer, the Company conducted an evaluation of the effectiveness of its internal control over financial reporting as defined in Exchange Act Rules 13a-15(f) and 15d-15(f) based on criteria established in Internal Control – Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on the Company’s evaluation, management concluded that the Company’s internal control over financial reporting was effective as of September 29, 2013.

PricewaterhouseCoopers LLP, the Company’s independent registered public accounting firm that audited the consolidated financial statements included in this Form 10-K, has audited the effectiveness of the Company’s internal control over financial reporting, as stated within their report which appears herein.
