ASC 326 requires the Company to record an estimate of expected lifetime credit losses for loans at the time of origination or acquisition. The ACL is maintained at a level deemed appropriate by management to provide for expected credit losses in the portfolio as of the date of the consolidated statements of financial condition. Estimating expected credit losses requires management to use relevant forward-looking information, including the use of reasonable and supportable forecasts. The measurement of the ACL is performed by collectively evaluating loans with similar risk characteristics. The Company measures the ACL on commercial real estate loans and commercial loans using a discounted cash flow approach, and a historical loss rate methodology is used to determine the ACL on retail loans. The Company’s discounted cash flow methodology incorporates a probability of default and loss given default model, as well as expectations of future economic conditions, using reasonable and supportable forecasts. Together, the probability of default and loss given default model with the use of reasonable and supportable forecasts generate estimates for cash flows expected and not expected to be collected over the estimated life of a loan. Estimates of future expected cash flows ultimately reflect assumptions made concerning net credit losses over the life of a loan. The use of reasonable and supportable forecasts requires significant judgment, such as selecting forecast scenarios and related scenario-weighting, as well as determining the appropriate length of the forecast horizon. Management leverages economic projections from a reputable and independent third party to inform and provide its reasonable and supportable economic forecasts. Other internal and external indicators of economic forecasts may also be considered by management when developing the forecast metrics. The Company’s ACL model reverts to long-term average loss rates for purposes of estimating expected cash flows beyond a period deemed reasonable and supportable. The Company forecasts probability of default and loss given default based on economic forecast scenarios over a two-year time horizon before reverting to long-term historical average loss rates over a period of three years. The duration of the forecast horizon, the period over which forecasts revert to long-term averages, the economic forecasts that management utilizes, as well as additional internal and external indicators of economic forecasts that management considers, may change over time depending on the nature and composition of our loan portfolio. Changes in economic forecasts, in conjunction with changes in loan specific attributes, impact a loan’s probability of default and loss given default, which can drive changes in the determination of the ACL.</span></div><div style="text-indent:36pt"><span><br/></span></div><div style="text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%">Expectations of future cash flows are discounted at the loan’s effective interest rate. The resulting ACL for term loans represents the amount by which the loan’s amortized cost exceeds the net present value of a loan’s discounted cash flows expected to be collected. The ACL for credit facilities is determined by discounting estimates for cash flows not expected to be collected. The ACL is recorded through a charge to provision for credit losses and is reduced by charge-offs, net of recoveries on loans previously charged-off. It is the Company’s policy to charge-off loan balances at the time they have been deemed uncollectible.</span></div><div style="text-indent:36pt"><span><br/></span></div><div style="text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%">The Company’s ACL model also includes adjustments for qualitative factors, where appropriate. Since historical information (such as historical net losses and economic cycles) may not always, by itself, provide a sufficient basis for determining future expected credit losses, the Company periodically considers the need for qualitative adjustments to the ACL. Qualitative adjustments may be related to and include, but not limited to factors such as: (i) management’s assessment of economic forecasts used in the model and how those forecasts align with management’s overall evaluation of current and expected economic conditions, (ii) organization specific risks such as credit concentrations, collateral specific risks, regulatory risks, and external factors that may ultimately impact credit quality, (iii) potential model limitations such as limitations identified through backtesting, and other limitations associated with factors such as underwriting changes, acquisition of new portfolios and changes in portfolio segmentation, and (iv) management’s overall assessment of the adequacy of the ACL, including an assessment of model data inputs used to determine the ACL.</span></div><div style="text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%">The Company has a credit portfolio review process designed to detect problem loans. Problem loans are typically those of a substandard or worse internal risk grade, and may consist of loans on nonaccrual status, troubled debt restructurings (“TDRs”), loans where the likelihood of foreclosure on underlying collateral has increased, collateral dependent loans and other loans where concern or doubt over the ultimate collectability of all contractual amounts due has become elevated. Such loans, which have exhibited a deterioration in credit quality may, in the opinion of management, be deemed to no longer possess risk characteristics similar to other loans in the loan portfolio, and as such may require individual evaluation to determine an appropriate ACL for the loan. When a loan is individually evaluated, the Company typically measures the expected credit loss for the loan based on a discounted cash flow approach, unless the loan has been deemed collateral dependent. Collateral dependent loans are loans where the repayment of the loan is expected to come from the operation of and/or eventual liquidation of the underlying collateral. The ACL for collateral dependent loans is determined using estimates for the fair value of the underlying collateral, less costs to sell.</span></div><div style="text-indent:36pt"><span><br/></span></div><div style="text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%">Although management uses the best information available to derive estimates necessary to measure an appropriate level of the ACL, future adjustments to the ACL may be necessary due to economic, operating, regulatory, and other conditions that may extend beyond the Company’s control. Additionally, various regulatory agencies, as an integral part of their examination process, periodically review the Company’s ACL and credit review process. Such agencies may require the Company to recognize additions to the ACL based on judgments different from those of management.</span></div><div><span><br/></span></div><div style="text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%">Please also see </span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-style:italic;font-weight:400;line-height:120%">Note 5 - Allowance for Credit Losses</span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:11pt;font-weight:400;line-height:120%">, of these Consolidated Financial Statements for additional discussion concerning the Company’s ACL methodology, including discussion concerning economic forecasts used in the determination of the ACL.</span></div>The Company has segmented the loan portfolio according to loans that share similar attributes and risk characteristics. Each segment possesses varying degrees of risk based on, among other things, the type of loan, the type of collateral, and the sensitivity of the borrower or industry to changes in external factors such as economic conditions. These segment groupings are: investor loans secured by real estate, business loans secured by real estate, commercial loans, and retail loans. Within each segment grouping there are various classes of loans as disclosed below. The Company determines the ACL for loans based on this more detailed loan segmentation and classification.

To qualify for hedge accounting, a derivative instrument must be highly effective at reducing the risk associated with the hedged exposure, and the hedging relationship must be formally documented at its inception. The Company uses regression analysis to assess the effectiveness of each hedging relationship, unless the hedge qualifies for other methods of assessing effectiveness (e.g., shortcut or critical terms match), both at inception and throughout the life of the hedge transaction.</span>The Company has derivative instruments designated as part of fair value hedges for accounting purposes. These derivatives consist of pay-fixed, receive-floating interest rate swaps, and were entered into to hedge changes in the fair value of fixed-rate assets for specific risks, such as interest rate risk resulting from changes in a benchmark interest rate. In a qualifying fair value hedge, the Company records periodic changes in the fair value of the derivative instrument in current period earnings. Simultaneously, periodic changes in the fair value of the hedged risk are also recorded in current period earnings. Together, these periodic changes in the fair value of the derivative instrument and the fair value of the hedged risk are included in the same line item of the statements of income associated with the hedged item (i.e. interest income), and largely offset each other. Interest accruals on both the derivative instrument and the hedged item are also recorded in the same line item, which effectively converts the designated fixed-rate assets to floating-rate assets. The Company structures these swaps to match the critical terms of the hedged items (i.e. fixed-rate loans), thereby maximizing the economic and accounting effectiveness of the hedging relationships and resulting in the expectation that the hedging relationship will be highly effective. If a fair value hedging relationship ceases to qualify for hedge accounting, hedge accounting is discontinued and future changes in the fair value of the derivative instrument are recognized in current period earnings, until the derivative is settled with the counterparty. In addition, all remaining basis adjustments resulting from periodic changes in the fair value of the hedged risk, previously recorded to the carrying amount of the hedged item, are amortized or accreted into interest income using the interest method over the remaining life of the hedged item.
