Non - GAAP Financial Measures The Company has for many years used a traditional efficiency ratio that is a non - GAAP financial measure of operating expense control and efficiency of operations. Management believes that its traditional ratio better focuses attention on the operating performance of the Company over time than does a GAAP ratio, and is highly useful in comparing period - to - period operating performance of the Company’s core business operations. It is used by management as part of its assessment of its performance in managing non - interest expenses. However, this measure is supplemental, and is not a substitute for an analysis of performance based on GAAP measures. The reader is cautioned that the non - GAAP efficiency ratio used by the Company may not be comparable to GAAP or non - GAAP efficiency ratios reported by other financial institutions. In general, the efficiency ratio is non - interest expenses as a percentage of net interest income plus non - interest income. Non - interest expenses used in the calculation of the non - GAAP efficiency ratio exclude goodwill impairment losses, the amortization of intangibles, and non - recurring expenses. Income for the non - GAAP ratio includes the favorable effect of tax - exempt income and excludes securities gains and losses, which vary widely from period to period without appreciably affecting operating expenses, and non - recurring gains. The measure is different from the GAAP efficiency ratio, which also is presented on slides 40 and 41. The GAAP measure is calculated using non - interest expense and income amounts as shown on the face of the Consolidated Statements of Income in audited financial statements. The GAAP and non - GAAP efficiency ratios are reconciled on slides 40 and 41. Tangible common equity and tangible assets are non - GAAP financial measures calculated using GAAP amounts. The Company calculates tangible common equity by excluding the balance of preferred stock, goodwill and other intangible assets from its calculation of stockholders’ equity. The Company calculates tangible assets by excluding the balance of goodwill an d other intangible assets from its calculation of total assets. Management believes that this non - GAAP financial measure provides information to investors that is useful in understanding the Company’s financial condition. Because not all companies use the same calculation of tangible common equity and tangible assets, this presentation may not be comparable to other similarly titled measures calculated by other companies. A reconciliation of the non - GAAP ratio of tangible common equity to tangible assets is provided on slides 42 and 43. 39 SASR; KBW 2017 Community Bank Investor Conference , August 1 - 2, 2017
