(a) Total revenues are comprised of net interest income and other income.  Net interest income is the difference between taxable-equivalent interest earned on assets and interest paid on liabilities owed by a segment and a funding charge (credit) based on the Company's internal funds transfer pricing and allocation 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 $6,725,000 and $6,248,000 for the three-month periods ended September 30, 2016 and 2015, respectively, and $19,579,000 and $18,106,000 for the nine-month periods ended September 30, 2016 and 2015, respectively, and is eliminated in "All Other" total revenues.  Intersegment revenues are included in total revenues of the reportable segments.  The elimination of intersegment revenues is included in the determination of "All Other" total revenues.
