These non-GAAP measures are intended to provide the reader with additional supplemental perspectives on operating results, performance trends, and financial condition. Non-GAAP financial measures are not a substitute for GAAP measures; they should be read and used in conjunction with the Company's GAAP financial information. A reconciliation of non-GAAP financial measures to GAAP measures is provided in the Appendix to this presentation. In all cases, it should be understood that non-GAAP measures do not depict amounts that accrue directly to the benefit of shareholders. An item which management excludes when computing non-GAAP adjusted earnings can be of substantial importance to the Company's results for any particular quarter or year. The Company's non-GAAP core earnings information set forth is not necessarily comparable to non-GAAP information which may be presented by other companies. Each non-GAAP measure used by the Company in this report as supplemental financial data should be considered in conjunction with the Company's GAAP financial information. The Company utilizes the non-GAAP measure of core earnings in evaluating operating trends, including components for core revenue and expense. These measures exclude amounts which the Company views as unrelated to its normalized operations, including securities gains/losses, acquisition costs, restructuring costs, legal settlements, and system conversion costs. Non-GAAP adjustments are presented net of an adjustment for income tax expense. The Company also calculates core earnings per share based on its measure of core earnings. The Company views these amounts as important to understanding its operating trends, particularly due to the impact of accounting standards related to acquisition activity. Analysts also rely on these measures in estimating and evaluating the Company's performance. Management also believes that the computation of non-GAAP core earnings and core earnings per share may facilitate the comparison of the Company to other companies in the financial services industry. The Company also adjusts certain equity related measures to exclude intangible assets due to the importance of these measures to the investment community. 3#4A Bank that Thinks Differently • BAR HARBOR BANKSHARES Bar Harbor Bank & Trust is the only community bank headquartered in Northern New England with branches in Maine, New Hampshire and Vermont.
