 applied to current loan balances to arrive at the quantitative baseline portion of the Allowance for most of the commercial portfolio segment.

The historical loss experience for the consumer portfolio segment is primarily determined using a Vintage method. This method measures historical loss behavior in the form of a historical loss rate for homogenous loan pools that originate in the same period, known as a vintage. The historical loss rates are then applied to origination loan balances by vintage to determine the quantitative baseline portion of the Allowance for most of the consumer portfolio segment. The homogenous loan pools are segmented according to similar risk characteristics (e.g., residential mortgage, home equity) and may be sub-segmented further based on historical loss behavior. For example, we sub-segment residential mortgages by geography and home equity by lien position.

We also consider qualitative adjustments to the quantitative baseline such as the impact of current environmental factors at the reporting date that did not exist over the period from which historical experience was used. Relevant factors include, but are not limited to, concentrations of credit risk, such as geography, industry, real estate property type; and economic trends and conditions, such as Hawaiʻi unemployment, real estate prices and market conditions, and visitor arrivals. We also consider changes in underwriting standards, and levels and trends in delinquencies and criticized loans and leases.

We also incorporate a reasonable and supportable (“R&S”) loss forecast period, which is currently one year, to account for the effect of forecasted economic conditions and other factors on the performance of the loan portfolios, which could differ from historical loss experience. We also perform asset quality reviews which includes a review of forecasted gross charge-offs and recoveries, nonperforming assets, criticized loans and leases, and risk rating migration. The results of the asset quality review are used to consider qualitative adjustments to the quantitative baseline. After the one-year R&S loss forecast period, this adjustment assumes an immediate reversion to historical loss rates for the remaining expected life of the loan.

The company utilizes the University of Hawaiʻi Economic Research Organization (“UHERO”) macroeconomic forecast that is updated quarterly based on economic conditions and events. The forecast includes various economic variables for Hawaiʻi such as gross domestic product (“GDP”), unemployment rate, visitor arrivals, residential real estate market conditions, personal income, and inflation rate. We also utilize other forecast tools for broader U.S. economic variables such as interest rates, as well as to apply any overlays to the forecast.
