The Bank makes loan modifications, primarily utilizing internal renegotiation programs via direct customer contact, that manage customers’ debt exposures held only by the Bank. Additionally, the Bank makes loan modifications with customers who have elected to work with external renegotiation agencies and these modifications provide solutions to customers’ entire unsecured debt structures. During the periods ended September 30, 2018 December 31, 2017, Once modified in a troubled debt restructuring, a loan is generally considered impaired until its contractual maturity. At the time of the restructuring, the loan is evaluated for an asset-specific allowance for credit losses. The Bank continues to specifically reevaluate the loan in subsequent periods, regardless of the borrower’s performance under the modified terms. If a borrower subsequently defaults on the loan after it is restructured, the Bank provides an allowance for credit losses for the amount of the loan that exceeds the value of the related collateral.

Loans with similar classifications are aggregated for purposes of the calculations. The allowance for loan losses, which was used to measure the credit risk, is subtracted from loans. Cash Value of Bank-Owned Life Insurance (“BOLI”) – The carrying amount approximates its fair value. Other Equity Securities – The carrying amount approximates its fair value. Deposits – The fair value of demand deposits and certain money market deposits is the amount payable at the reporting date. The fair value of fixed-maturity certificates of deposit is estimated using discounted cash flow analyses, with interest rates currently offered for deposits of similar remaining maturities.
