Under current U.S. generally accepted accounting principles, companies generally recognize credit losses when it is probable that the loss has been incurred.

Management plans to use the Net Present Value of Discounted Cash Flow methodology for all loan pools and expects the implementation of ASU No. 2016-13 to increase the balance of the allowance for loan losses by less than 10%. In addition, a reserve for unfunded commitments will need to be established and Management expects it to be in a range of 0.25% to 0.50% of the amount of unfunded commitments that are not unconditionally cancellable. Management continues to evaluate the modeling and its potential impact on the Corporation's results of consolidated operations and financial position and, once the new guidance is adopted, the allowance for loan losses and reserve for unfunded commitments will increase through a one-time adjustment to retained earnings. The Corporation is also developing disclosure documentation related to adoption of this standard. The Corporation is planning to adopt this new guidance within the time frame noted above.

Recently Issued Accounting Pronouncements Not Yet Effective: In June 2016, the Financial Accounting Standards Board (FASB) issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This ASU adds a new Topic 326 to the codification and removes the thresholds that companies apply to measure credit losses on financial instruments measured at amortized cost, such as loans, receivables, and held-to-maturity debt securities.
