Column (f) Total shareholder return (“TSR”) is calculated by assuming that a $100 investment was made on the day prior to the first fiscal year reported below and reinvesting all dividends until the last day of each reported fiscal year.

Column (g) The peer group utilized in the table above is the Nasdaq Composite Index, as used in the company’s performance graph in our annual report.
