The increase in ACL at December 31, 2020 as compared to December 31, 2019, is primarily attributable to the initial adoption of the CECL lifetime loss accounting model and the impact of current and forecasted macroeconomic conditions on credit models, which were negatively affected by the emergence of the COVID-19 pandemic in 2020.

Credit Quality Indicators. To measure credit risk for the commercial portfolio, the Company employs a dual grade credit risk grading system for estimating the PD and LGD. This credit risk grading system has not changed with the adoption of CECL. The credit risk grade system assigns a rating to each borrower and to the facility, which together form a Composite Credit Risk Profile. The credit risk grade system categorizes borrowers by common financial characteristics that measure the credit strength of borrowers and facilities by common structural characteristics. The Composite Credit Risk Profile has ten grades, with each grade corresponding to a progressively greater risk of loss. Grades (1) to (6) are considered pass ratings and (7) to (10) are considered criticized, as defined by the regulatory agencies. Risk ratings, assigned to differentiate risk within the portfolio, are reviewed on an ongoing basis and revised to reflect changes in a borrowers’ current financial position and outlook, risk profile, and the related collateral and structural position. Loan officers review updated financial information on at least an annual basis for all pass rated loans to assess the accuracy of the risk grade. Criticized loans undergo more frequent reviews and enhanced monitoring. A (7)-"Special Mention" rating has a potential weakness that, if left uncorrected, may result in deterioration of the repayment prospects for the credit. A (8)-"Substandard" rating has a well-defined weakness that jeopardizes the full repayment of the debt. A (9)-"Doubtful" rating has all of the same weaknesses as a substandard credit with the added characteristic that the weakness makes collection or liquidation in full, given current facts, conditions, and values, improbable. Credits when classified as (10)-"Loss," in accordance with regulatory guidelines, are considered uncollectible and charged off.

To measure credit risk for the consumer portfolio, the most relevant credit characteristic is the FICO score, which is a widely used credit scoring system that ranges from 300 to 850. A lower FICO score is indicative of higher credit risk. FICO scores are updated at least quarterly.
