Additionally, The Bank of Maine, a wholly owned subsidiary of SBM, merged with and into Camden National Bank, with Camden National Bank continuing as the surviving bank. Pursuant to the Merger Agreement, each share of SBM common stock outstanding at the effective time of the Merger was converted into the right to receive, at the election of the stockholder and subject to the allocation and proration procedures described in the Merger Agreement, either: (1) $206.00 in cash, without interest or (2) 5.421 shares of common stock of the Company; provided that 80% of the SBM shares outstanding immediately prior to the effective time of the Merger were converted into the right to receive common stock of the Company and the remaining SBM shares were converted into the right to receive cash.

In addition, the Company incurred certain equity issuance costs totaling $537,000 related to the registration of additional shares of the Company's common stock. These costs have been accounted for as a reduction to shareholders' equity. In accordance with the Internal Revenue Code, certain non-recurring costs are not deductible for income tax purposes. The impact to the Company's effective tax rate for the nine months ended September 30, 2015 was an increase of 2.1%.
