Noninterest expense increased $167,000 on a linked quarter basis primarily as a result of an increase in salaries and employee benefits.  Major expense categories were generally flat or down in the first quarter of 2016 compared to the same period in 2015 most notably in debit card interchange expense and OREO expense.

Non-GAAP Presentations: Management has traditionally disclosed certain non-GAAP ratios to evaluate and measure the Company’s performance, including a net interest margin calculation.  The net interest margin is calculated by dividing net interest income on a tax equivalent basis by average earning assets for the period.  Management believes this measure provides investors with information regarding balance sheet profitability.  Consistent with industry practice, management also disclosed other non-GAAP measures in the discussion above and in the following tables.  The efficiency ratio is discussed in the noninterest expense presentation on page 4.  The tables provide a reconciliation of each non-GAAP measure to the most comparable GAAP equivalent.
