 borrowers may be unable to meet contractual principal or interest obligations, or where interest or principal is 90 days or more past due, unless the loans are adequately secured and in the process of collection. Cash receipts on non-accrual loans are generally applied to the principal balance until the remaining balance is considered collectible, at which time interest income may be recognized when received.  Allowance for Credit LossesIn accordance with ASC 326, “Financial Instruments – Credit Losses” (“ASC 326”), the Company measures the allowance for credit losses at the time of origination or purchase of a financial asset, representing an estimate of lifetime expected credit losses on the related asset.

leases recognized by a lessor, held-to-maturity debt securities and purchased credit deteriorated (“PCD”) assets at the time of and subsequent to acquisition, and off-balance-sheet credit exposures considered not unconditionally cancellable.

The Company utilizes modeling methodologies that estimate lifetime credit loss rates on each pool, including methodologies estimating the probability of default and loss given default on specific segments. Credit quality indicators, specifically the Company's internal risk rating systems, reflect how the Company monitors credit losses and represent factors used by the Company when measuring the allowance for credit losses. Historical credit loss history is adjusted for reasonable and supportable forecasts developed by the Company and incorporates third party economic forecasts on a quantitative or qualitative basis.

For periods beyond the ability to develop reasonable and supportable forecasts, the Company reverts to historical loss rates. Qualitative factors assessed by Management include the following:•Changes in the nature and
