(a)

Net interest income is the difference between actual taxable-equivalent interest earned on assets and interest paid on liabilities by a segment and a funding charge (credit) based on the Company’s internal funds transfer pricing methodology. Segments are charged a cost to fund any assets (e.g. loans) and are paid a funding credit for any funds provided (e.g. deposits). The taxable-equivalent adjustment aggregated $26,962,000 in 2016, $24,463,000 in 2015 and $23,642,000 in 2014 and is eliminated in “All Other” net interest income and income tax expense (benefit).
