Pro Forma Information

The following table presents certain unaudited pro forma information for illustrative purposes only, for the three months ended March 31, 2016 and 2015 as if Starbuck had been acquired on January 1, 2014. This unaudited estimated pro forma financial information combines the historical results of Starbuck with the Company’s consolidated historical results. Pro forma adjustments include accretion of loan discount, accretion of investment premiums, amortization of deposit premium, amortization of CDI, reversal of acquisition expense, and reversal of historical recorded amounts for similar items, with all adjustments tax effected. The pro forma information is not indicative of what would have occurred had the acquisition actually occurred on January 1, 2014. In particular, no adjustments have been made to eliminate the impact of other-than-temporary impairment losses and losses recognized on the sale of securities that may not have been necessary had the investment securities been recorded at fair value as of January 1, 2014. The unaudited pro forma information does not consider any changes to the provision for credit losses resulting from recording loan assets at fair value. Additionally, Banner expects to achieve further operating cost savings and other business synergies, including revenue growth, as a result of the acquisition which are not reflected in the pro forma amounts that follow. As a result, actual amounts would have differed from the unaudited pro forma information presented (in thousands except per share amounts):
