Financial Overview

Total loans were $2.6 billion and increased $4.4 million, or 0.7% annualized, as higher levels of payoffs and paydowns offset $163.4 million in first quarter originations. Total loans at March 31, 2016 increased $375.8 million, or 17.0%, since March 31, 2015. Fully taxable equivalent net interest income totaled $39.0 million for the first quarter of 2016, a $1.8 million decrease from the prior quarter primarily driven by a narrowing of the fully taxable equivalent net interest margin by 5 basis points to 3.68% as the earning asset yield decreased 4 basis points. Net charge-offs in the non 310-30 portfolio were 0.10% of average non 310-30 loans during the first quarter compared to 0.36% in the prior quarter. Continued weakness in the energy industry drove an increase in the energy sector allowance for loan losses of $10.7 million, or a negative $0.22 per share, resulting in a total allowance for loan losses on energy sector loans of 11.0% of energy loan balances. Average transaction deposits totaled $2.6 billion, consistent with prior quarter. Banking related non-interest income totaled $7.5 million, decreasing $1.1 million, driven by a seasonal decrease in service charges of $0.6 million, coupled with a $0.7 million negative mark-to-market adjustment related to fair value interest rate swaps on fixed-rate term loans. Non-interest expense totaled $34.9 million, decreasing $7.3 million as we are realizing the benefits of several efficiency initiatives. Executed share buybacks through April 20th of this year of 1.5 million shares, or $28.6 million at a weighted average price of $19.66. At March 31, 2016, tangible common book value per share was $18.51 before consideration of the excess accretable yield value of $1.08 per share.
