MEMO DATE: April 28, 2016 TO: Home Federal Bank Employees FROM Jason Wallen, Learning & Development Manager RE: Travel Expenses Related to HFB Integration Training As we move closer to bank conversion weekend, Home Federal Bank Integration Training will soon be in full swing. Most employees have reviewed the Integration Training Course Catalog & Calendar and signed up for the courses relevant to their role. The following courses are offered in a hands-on, training room setting and attendance may cause some HFB employees to incur travel expenses: Branch Operations General Loan Inquiry & Systems Review Introduction to Consumer Lending Streamline – Deposit Platform Vertex Teller / VSoft Branch Capture Please, review the information below to understand how Great Western Bank will process needed hotel reservations and additional travel expenses prior to conversion. Timecards Until further notice, HFB employees are asked to follow their existing HFB policy in regards to reporting their time while traveling and attending training classes. GWB will provide its policy and more direction will be provided to employees to cover any changes in the near future. Hotel Reservations The following criteria should be used to determine if an employee would require a hotel reservation for a specific training class: The employee must travel more than 90 minutes, from the employee’s regular branch location, to attend any single day training class. The employee must travel more than 60 minutes, from the employee’s regular branch location, for any two consecutive days of training classes. Learning & Development (L&D) has contacted Branch Managers at locations which fit these criteria. L&D will gather the information necessary to arrange hotel accommodations on each employee’s behalf. Lodging expenses will be direct billed by the hotel to a GWB Corporate Credit Card. HFB employees will not be required to individually pay for these hotel rooms. L&D will address any specific hotel booking questions with branch employees when providing the final reservation information. Filed by Great Western Bancorp, Inc.
