Financial Overview 20

Third Quarter 2015 Results Summary Total loans grew $194.6 million driven by $253.7 million of originations and the acquisition of Pine River. Excluding Pine River, total loans grew $131.7 million, or 22.4% annualized.   Annualized non 310-30 net charge-offs were only 0.02% of average non 310-30 loans. Non-performing loans increased $13.6 million and resulted in a non-performing loan to total loans ratio of 1.14%.    Successfully exited $13.1 million, or 33.1% annualized, of the remaining non-strategic loan portfolio. Added a net $0.8 million to accretable yield for the acquired loans accounted for under ASC 310-30. Average transaction deposits increased $43.7 million or 7.0% annualized, excluding $66.3 million from Pine River. The strong transaction deposit growth coupled with lower time deposits resulted in a two basis point lowering of the cost of deposits.  Net interest income totaled $38.7 million, a $0.2 million decrease from the prior quarter. The quarterly decrease was primarily driven by lower levels of higher-yielding purchased loans.  FDIC loss-share related non-interest income totaled a negative $5.8 million, primarily related to non-cash amortization of the FDIC indemnification asset.    Banking fee income totaled $6.8 million, a $0.4 million or 22.6% annualized increase from the prior quarter. Non-interest expense totaled $38.7 million, decreasing $1.7 million or 4.2% from the prior quarter. Repurchased 4.8 million shares during the third quarter, or 13.6% of outstanding shares, at a weighted average price of $19.88. Since early 2013, 22.1 million shares have been repurchased, or 42.3% of then outstanding shares.  At September 30, 2015, tangible common book value per share was $18.31 before consideration of the excess accretable yield value of $1.11 per share.  Completed the acquisition of Pine River on August 1, 2015 for $9.5 million cash. The acquisition resulted in a $1.0 million bargain purchase gain. Assets and liabilities recorded at fair value included cash and investments of $64.2 million; loans of $64.3 million; and deposits of $130.1 million.
