The amount of ACL is based on ongoing, quarterly assessments by management. The CECL methodology requires an estimate of the credit losses expected over the life of an exposure (or pool of exposures) and replaces the incurred loss methodology’s threshold that delayed the recognition of a credit loss until it was probable a loss event was incurred.</span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The ACL consists of the allowance for loan losses and the reserve for unfunded commitments. The estimate of expected credit losses under the CECL methodology is based on relevant information about past events, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amounts. Historical loss experience is generally the starting point for estimating expected credit losses. We then consider whether the historical loss experience should be adjusted for asset-specific risk characteristics or current conditions at the reporting date that did not exist over the period that historical experience was based for each loan type. Finally, we consider forecasts about future economic conditions or changes in collateral values that are reasonable and supportable. </span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Portfolio segment is defined as the level at which an entity develops and documents a systematic methodology to determine its ACL. The Company has designated two loan portfolio segments, commercial loans and consumer loans. These loan portfolio segments are further disaggregated into classes, which represent loans of similar type, risk characteristics, and methods for monitoring and assessing credit risk. The commercial loan portfolio segment is disaggregated into five classes: multi-family, commercial real estate, commercial and industrial, construction, and land acquisition and development. The risk of loss for the commercial loan portfolio segment is generally most indicated by the credit risk rating assigned to each borrower. Commercial loan risk ratings are determined by experienced senior credit officers based on specific facts and circumstances and are subject to periodic review by an independent internal team of credit specialists. The consumer loan portfolio segment is disaggregated into five classes: single-family-residential mortgage, custom construction, consumer lot loans, home equity lines of credit, and other consumer. The risk of loss for the consumer loan portfolio segment is generally most indicated by delinquency status and general economic factors. Each commercial and consumer loan portfolio class may also be further segmented based on risk characteristics.</span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">For most of our loan portfolio classes, the historical loss experience is determined using a cohort methodology. This method pools loans into groups (“cohorts”) sharing similar risk characteristics and tracks each cohort’s net charge-offs over the lives of the loans to calculate a historical loss rate. The historical loss rates for each cohort are then averaged to calculate an overall historical loss rate which is applied to the current loan balance to arrive at the quantitative baseline portion of the allowance for credit losses for the respective loan portfolio class. For certain loan portfolio classes, the Company determined there was not sufficient historical loss information to calculate a meaningful historical loss rate using the cohort methodology. For any such loan portfolio class, the weighted-average remaining maturity (“WARM”) methodology is being utilized until sufficient historical loss data is obtained. The WARM method multiplies an average annual loss rate by the expected remaining life of the loan pool to arrive at the quantitative baseline portion of the allowance for credit losses for the respective loan portfolio class. </span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The Company also considers qualitative adjustments to the historical loss rate for each loan portfolio class. The qualitative adjustments for each loan class consider the conditions over the period from which historical loss experience was based and are split into two components: 1) asset or class specific risk characteristics or current conditions at the reporting date related to portfolio credit quality, remaining payments, volume and nature, credit culture and management, business environment or other management factors and 2) reasonable and supportable forecast of future economic conditions and collateral values. </span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The Company performs a quarterly asset quality review which includes a review of forecasted gross charge-offs and recoveries, nonperforming assets, criticized loans, risk rating migration, delinquencies, etc. The asset quality review is performed by management and the results are used to consider a qualitative overlay to the quantitative baseline. The second qualitative adjustment noted above, economic conditions and collateral values, encompasses a one-year reasonable and supportable forecast period. The overlay adjustment for the reasonable and supportable forecast assumes an immediate reversion after the one-year forecast period to historical loss rates for the remaining life of the respective loan pool. </span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">When management deems it to be appropriate, the Company establishes a specific reserve for individually evaluated loans that do not share similar risk characteristics with the loans included in each respective loan pool. These individually evaluated loans </span></div>are removed from their respective pools and typically represent collateral dependent loans but may also include other non-performing loans or troubled debt restructurings (“TDRs”). In addition, the Company individually evaluates “reasonably expected” TDRs, which are identified by the Company as a loan expected to be classified as a TDR within the next six months. Management judgment is utilized to make this determination.
