 factors. The allowance for credit losses is comprised of reserves measured on a collective (pool) basis when similar risk characteristics exist. Loans that do not share risk characteristics are assigned a reserve based on an individual evaluation and are not included in the collective (pool) evaluation. For purposes of determining the collective (pool) allowance for credit losses, the loan portfolio is segregated into pools first by portfolio segment and then by past due status or credit grade. Each pool is assigned a loss estimate, reflecting historical loss rates that incorporate probability of default and severity of losses over the estimated remaining life of the loans. These loss estimates are then modified to incorporate a reasonable and supportable forecast of future losses at the pool level, as well as any necessary qualitative adjustments using a Portfolio Level Qualitative Factor (“PLQF”)

and/or a Portfolio Segment Level Qualitative Factor (“SLQF”). A similar process is employed to calculate a reserve assigned to off-balance financial instruments, specifically unfunded loan commitments and letters of credit. Modified loss estimates are assigned based on the balance of the commitments estimated to be outstanding at the time of default. The PLQF and SLQF are utilized to address factors that are not present in historical loss rates and are otherwise unaccounted for in the quantitative process. The PLQF is used to apply a qualitative adjustment across the entire portfolio of loans, while the SLQF is designed to apply a qualitative adjustment across a single portfolio segment. Even though portions of the allowance may be allocated to specific loans, the entire allowance is available for any credit that, in management’s judgment, should be charged off. The Company generally uses a two-year forecast period, based on a single forecast scenario or a blend of multiple forecast scenarios, using variables management believes are most relevant to each portfolio segment. For periods beyond which management is able to develop reasonable and supportable forecasts, the Company reverts to the average historical loss rate, reflecting historical default probabilities and loss severities, using a reversion speed that approximates 1 to 2 years. The forecast period and scenario(s) used are reviewed on a quarterly basis and may be adjusted based on management's view of the current economic conditions and level of predictability the forecast can provide.Portfolio segments are used to pool loans with similar risk characteristics and align with the Company’s methodology for measuring expected credit losses. A summary of the primary portfolio segments is as follows:Commercial. The commercial loan portfolio is comprised of lines of credit for working capital, term loans, reserve-based loans to energy exploration and
