Basis of Presentation: The unaudited condensed consolidated financial statements have been prepared in conformity with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles (“U.S. GAAP”) for complete financial statements. The financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s 2013 Annual Report to Shareholders included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013. The interim consolidated financial statements include all adjustments (consisting of only normal recurring items) that, in the opinion of management, are necessary for a fair presentation of the financial position and results of operations for the periods presented. The results of operations for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for a full year. Estimates: The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The allowance for loan losses, deferred tax assets, carrying amount of goodwill and fair values of financial instruments are particularly subject to change. Segments: The Company provides a broad range of financial services to individuals and companies in northeastern Ohio. Operations are managed and financial performance is primarily aggregated and reported in three lines of business, the Bank segment, the Trust segment and the Retirement Consulting segment. Comprehensive Income (Loss): Comprehensive income (loss) consists of net income and other comprehensive income (loss). Other comprehensive income (loss) consists of unrealized gains and losses on securities available for sale and changes in the funded status of the post-retirement health plan, which are recognized as separate components of equity, net of tax effects. For the three and six month periods ended June 30, 2014, there was no change in the funded status of the post-retirement health plan. Newly Issued but Not Yet Effective Accounting Standards: In May 2014, FASB issued Accounting Standards Update 2014-04, Revenue from Contracts with Customers (Topic 606). The ASU creates a new topic, Topic 606, to provide guidance on revenue recognition for entities that enter into contracts with customers to transfer goods or services or enter into contracts for the transfer of nonfinancial assets. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Additional disclosures are required to provide quantitative and qualitative information regarding the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The new guidance is effective for annual reporting periods, and interim reporting periods within those annual periods, beginning after December 15, 2016. Early adoption is not permitted. Management is currently evaluating the impact of the adoption of this guidance on the Corporation’s financial statements.
