Management utilizes a systematic, documented approach in determining the appropriate level of the ACL. Management’s approach provides for estimated credit losses on loans in accordance with ASU No. 2016-13, <span style="font-style:italic; ">Financial Instruments – Credit Losses </span><span style="font-style:italic; ">(Topic 326): Measurement of Credit Losses on Financial Instruments</span>. These estimates are based upon a number of factors, such as payment history, financial condition of the borrower, expected future cash flows and collateral exposure. </p> <p style="font-family:Times New Roman, Times, serif; font-size:10pt; text-align:justify; margin-top:11pt; margin-bottom:0pt; ">The ACL is a valuation account that is deducted from the amortized cost basis to present the net amount expected to be collected on the loans. Loans are charged off against the ACL when management believes the uncollectibility of a loan balance is confirmed. Expected recoveries for amounts previously charged off and expected to be charged off do not exceed the aggregate of amounts previously charged off and expected to be charged off. </p> <p style="font-family:Times New Roman, Times, serif; font-size:10pt; text-align:justify; margin-top:11pt; margin-bottom:0pt; ">Management estimated the allowance balance using relevant available information from internal and external sources, relating to past events, current conditions and reasonable and supportable forecasts based on economic factors, such as GDP. Historical credit loss experience, of both the Company and similar peer banks, provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for lending management experience, asset quality trends, borrower’s ability to pay, collateral, and other environmental factors. The ACL is measured on a collective pool basis when similar risk characteristics exist. Management believes the ACL is adequate to absorb expected losses in the loan portfolio. </p> <p style="font-family:Times New Roman, Times, serif; font-size:10pt; text-align:left; margin-top:11pt; margin-bottom:0pt; "><span style="font-style:italic; ">Loans</span></p> <p style="font-family:Times New Roman, Times, serif; font-size:10pt; text-align:justify; margin-top:0pt; margin-bottom:0pt; ">The ACL is measured on a collective pool basis when similar risk characteristics exist.

These loans are generally collateralized by inventory, accounts receivable, equipment, and other commercial assets, and may be supported by other credit enhancements such as personal guarantees. Risk arises primarily due to a difference between expected and actual cash flows of the borrower. However, the recoverability of these loans is also dependent on other factors primarily dictated by the type of collateral securing these loans. The fair value of the collateral securing these loans may fluctuate as market conditions change. Included within C&I are revolving loans supported by borrowing bases that fluctuate depending on the amount of underlying collateral. </p> <p style="font-family:Times New Roman, Times, serif; font-size:10pt; text-align:justify; margin-top:11pt; margin-bottom:0pt; "><span style="font-style:italic; ">Commercial Real Estate (“CRE”)</span> – CRE loans include various types of loans for which the Company holds real property as collateral. Commercial real estate lending activity is typically restricted to owner-occupied properties or to investor properties that are owned by customers with a current banking relationship. The primary risks of CRE loans include the borrower’s inability to pay and material decreases in the value of the real estate being held as collateral. </p> <p style="font-family:Times New Roman, Times, serif; font-size:10pt; text-align:justify; margin-top:11pt; margin-bottom:0pt; "><span style="font-style:italic; ">Faith-based CRE</span> – Faith-based CRE loans include loans to faith-based ministries for which the Company holds real property as collateral.

Construction loans are generally collateralized by first liens on the real estate and have floating interest rates. The primary risks of construction loans are construction completion and timing risk. Adverse economic conditions may negatively impact the borrowers’ ability to complete the project. Additionally, the fair value of the underlying collateral may fluctuate as market conditions change. </p> <p style="font-family:Times New Roman, Times, serif; font-size:10pt; text-align:justify; margin-top:11pt; margin-bottom:0pt; ">The ACL is calculated as the difference between the amortized cost basis and the projections from the weighted-average remaining maturity ("WARM") model that the Company developed. The WARM model utilizes an attrition analysis, including events such as payoffs, matured loans, and renewals in the borrowers’ control, to anticipate the length of time it would take for each portfolio segment to runoff. Management incorporates a one year GDP forecast and an immediate reversion to peer historical loss rates to determine the annual charge off rates over the estimated life of the loans. After the reasonable and supportable forecast period, the model reverts to long-run historical average loss rates of its peers. However, for the faith-based CRE ACL, beyond the reasonable and supportable forecast period, loss rates are reverted immediately to the Company’s long-run historical averages, as this represents a unique loan segment to the peer portfolios. The economic forecast is based on management’s assessment of the length and pattern of the current economic cycle. The resulting annual charge off rate determined for each year in the WARM model is applied to the loan balances estimated in the attrition analysis. </p> <p style="font-family:Times New Roman, Times, serif; font-size:10pt; text-align:justify; margin-top:11pt; margin-bottom:0pt; ">Management accounts for the inherent uncertainty of the underlying economic forecast by reviewing forecast scenarios.

These qualitative adjustments may increase or reduce reserve levels and include adjustments for lending management experience and risk tolerance, loan review and audit results, asset quality and portfolio trends, loan portfolio growth and loan concentrations. The Company has elected to exclude accrued interest receivable ("AIR") from the allowance for credit losses calculation. When a loan is placed on non-accrual, any recorded AIR is reversed against interest income. </p> <p style="font-family:Times New Roman, Times, serif; font-size:10pt; text-align:justify; margin-top:11pt; margin-bottom:0pt; ">The determination and application of the ACL accounting policy involves judgments, estimates, and uncertainties that are subject to change. Changes in these assumptions, estimates or the conditions surrounding them may have a material impact on the Company’s financial condition, liquidity or results of operations. Various regulatory agencies, as an integral part of the examination process, periodically review the ACL. Such agencies may require the Company to recognize additions to the ACL or reserve increases to adversely graded classified loans based on information available to them at the time of their examinations. </p> <p style="font-family:Times New Roman, Times, serif; font-size:10pt; text-align:justify; margin-top:11pt; margin-bottom:0pt; ">The ACL is decreased by net charge-offs and is increased by provisions for credit losses that are charged to the consolidated statements of operations. Charge-offs, if any, are typically measured for each loan based on a thorough analysis of the most probable source of repayment, such as the present value of the loan’s expected future cash flows, the loan’s estimated fair value, or the estimated fair value of the underlying collateral less costs of disposition for collateral-dependent loans. When it is determined that specific loans, or portions thereof, are uncollectible, these amounts are charged off against the ACL. </p> <p style="font-family:Times New Roman, Times, serif; font-size:10pt; text-align:left; margin-top:11pt; margin-bottom:0pt; "><span style="font-style:italic; ">Unfunded loan commitments</span></p> <p style="font-family:Times New Roman, Times, serif; font-size:10pt; text-align:justify; margin-top:0pt; margin-bottom:0pt; ">In addition to the ACL for funded loans, the Company maintains reserves to cover the risk of loss associated with off-balance sheet unfunded loan commitments. The allowance for off-balance sheet credit losses is maintained within other liabilities in the statements of financial condition. Under the CECL framework, adjustments to this liability are recorded as provision for credit losses in the consolidated statements of operations. Unfunded loan commitment balances are evaluated by loan segment. In order to establish the required level of reserve, the Company applies average historical utilization rates and ACL loan model loss rates for each loan segment to the outstanding unfunded commitment balances. </p> <p style="font-family:Times New Roman, Times, serif; font-size:10pt; text-align:left; margin-top:11pt; margin-bottom:0pt; "><span style="font-style:italic; ">Investment securities</span></p> <p style="font-family:Times New Roman, Times, serif; font-size:10pt; text-align:justify; margin-top:0pt; margin-bottom:0pt; ">Management evaluates all investments in an unrealized loss position on a quarterly basis, and more frequently when economic or market conditions warrant such evaluation. If the Company has the intent to sell the security or it is more likely than not that the Company will be required to sell the security, the security is written down to fair value and the entire loss is recorded in earnings. If either of the above criteria is not met, the Company will evaluate whether the decline in fair value is the result of credit losses or other factors. In making the assessment, the Company may consider various factors including the extent to which fair value is less than amortized cost, performance on any underlying collateral, downgrades in the ratings of the security by a rating agency, the failure of the issuer to make scheduled interest or principal payments and adverse conditions specifically related to the security. If the assessment indicates that a credit loss exists, the present value of cash flows expected to be collected are compared to the amortized cost basis of the security and any excess is recorded as an allowance for credit loss. For U.S. agency-backed securities where the risk of nonpayment of the amortized cost basis is zero, the Company will not measure expected credit losses on these securities. When the loss is not considered a result of credit loss, the cost basis of the security is written down to fair value, with the loss charge recognized in AOCI. Credit losses are not estimated for AIR from investment securities as interest deemed uncollectible is written off through interest income. </p>

The declaration of a global pandemic indicates that almost all public commerce and related business activities must be, to varying degrees, curtailed with the goal of decreasing the rate of new infections. This response to the COVID-19 pandemic has resulted in an unprecedented slow-down in economic activity and a related increase in unemployment. </p> <p style="font-family:Times New Roman, Times, serif; font-size:10pt; text-align:justify; margin-top:11pt; margin-bottom:0pt; ">In late fiscal 2020, vaccines for combatting COVID-19 were approved by health agencies and began to be administered. However, initial quantities of vaccines are limited and vaccine distributions, controlled by local authorities, are being allocated, generally first to front-line health care workers and other essential workers and next to those members of individual populations believed most susceptible to severe effects from COVID-19. The timeline of full administration of the COVID-19 vaccines is uncertain and fluctuating, but is widely thought to be unlikely to occur in most jurisdictions until mid to late 2021. The impact of COVID-19, including the impact of restrictions imposed to combat its spread, could result in additional and prolonged business closures, work restrictions and activity restrictions. </p> <p style="font-family:Times New Roman, Times, serif; font-size:10pt; text-align:justify; margin-top:11pt; margin-bottom:0pt; ">The Company has evaluated subsequent events after the consolidated balance sheet date of December 31, 2020 and the breadth of the impact of the global presence of COVID-19 on the Company’s business is currently unknown. The Company is closely monitoring developments related to COVID-19 checking regularly for updated information and recommendations from the WHO and the CDC, from national, state, and local governments, and evaluating courses of action being taken by peers. The duration and severity of the effect of COVID-19 on economic, market and business conditions and the timeline and shape of recovery from the pandemic remain uncertain. At this time, the Company remains subject to heightened business, operational, market, credit and other risks related to the COVID-19 pandemic, including, but not limited to, those discussed below, which may have an adverse effect on business, financial condition and results of operations. </p> <p style="font-family:Times New Roman, Times, serif; font-size:10pt; text-align:justify; margin-top:11pt; margin-bottom:0pt; ">Financial position and results of operations - The global health crisis caused by COVID-19 has and will continue to negatively impact business activity throughout the world. The COVID-19 outbreak and associated counter-acting measures implemented by governments around the world, as well as increased business uncertainty, have had, and continue to have, an adverse impact on the Company’s financial results and are discussed in more detail below. Although in various locations certain activity restrictions have been relaxed with some success, many states and localities are experiencing significant increases in the number of COVID-19 cases, prompting a reinstatement of prior activity restrictions in some locations and the need for additional aid and other forms of relief for affected individuals, businesses and other entities. When and if COVID-19 is demonstrably contained, the Company anticipates a rebound in economic activity; however, any such rebound is contingent upon the rate and effectiveness of the containment efforts deployed by federal, state, and local governments. In light of the evolving health, social, economic and business environment, governmental regulations or mandates, and business disruptions that have occurred and could continue to occur, the aggregate impact that COVID-19 could have on the Company’s financial condition and operating results remains highly uncertain. </p> <p style="font-family:Times New Roman, Times, serif; font-size:10pt; text-align:justify; margin-top:11pt; margin-bottom:0pt; ">In response to COVID-19, the Federal Reserve has taken action to lower the Federal Funds rate, which has adversely affected interest income and therefore, the Company’s results of operations and financial condition.

Future asset impairment charges, increases in allowance for credit losses, or restructuring charges could be more likely and will be dependent on the severity and duration of this crisis and its effect on the Company’s borrowers. </p> <p style="font-family:Times New Roman, Times, serif; font-size:10pt; text-align:justify; margin-top:11pt; margin-bottom:0pt; ">For payment processing services, business closures, including constrictions in the manufacturing sector, have led to a decrease in the number of transactions and dollars processed due to the decline in customers’ business activity. In addition, the dampened demand for oil and resulting plummet in oil prices has had, and can continue to have, a negative effect on both the number of freight transactions processed and the dollar amount of invoices processed. Other financial impact could occur though such potential impact is unknown at this time. </p> <p style="font-family:Times New Roman, Times, serif; font-size:10pt; text-align:justify; margin-top:11pt; margin-bottom:0pt; ">Capital and liquidity - While the Company believes that it has sufficient capital to withstand an extended economic recession brought about by COVID-19, its reported and regulatory capital ratios could be adversely impacted by future financial losses. </p> <p style="font-family:Times New Roman, Times, serif; font-size:10pt; text-align:justify; margin-top:11pt; margin-bottom:0pt; ">The Company maintains access to multiple sources of liquidity. If funding costs are elevated for an extended period of time, it could have an adverse effect on the Company’s net interest margin. If an extended recession caused large numbers of the Bank’s customers to draw down deposits, the Company might become more reliant on more expensive sources of funding. </p> <p style="font-family:Times New Roman, Times, serif; font-size:10pt; text-align:justify; margin-top:11pt; margin-bottom:0pt; ">Asset valuation - Currently, the Company does not expect COVID-19 to affect its ability to fairly value the assets on its balance sheet; however, this could change in future periods. While certain valuation assumptions and judgments will change to account for pandemic-related circumstances such as widening credit spreads, the Company does not anticipate significant changes in methodology used to determine the fair value of assets measured in accordance with GAAP. </p> <p style="font-family:Times New Roman, Times, serif; font-size:10pt; text-align:justify; margin-top:11pt; margin-bottom:0pt; ">The economic slowdown as a result of COVID-19 could cause a further and sustained decline in the Company’s stock price or the occurrence of what management would deem to be a triggering event that could, under certain circumstances, necessitate a goodwill or intangible asset impairment test and result in an impairment charge being recorded for that period. In the event that the Company concludes that all or a portion of its goodwill is impaired, a non-cash charge for the amount of such impairment would be recorded to earnings. Such a charge would have no impact on tangible capital or regulatory capital. </p> <p style="font-family:Times New Roman, Times, serif; font-size:10pt; text-align:justify; margin-top:11pt; margin-bottom:0pt; ">Processes, controls and business continuity - In accord with its federally mandated Pandemic Plan and Business Continuity Plan, Cass has deployed its remote workforce program. Most Cass employees around the globe are now working and conducting business remotely. Employees necessary to oversee certain business coordination activities or to conduct essential physical activities such as mail handling and scanning operations, remain in offices. In addition, employees are now being permitted to return to the offices on a voluntary basis. Employees are required to report any exposure or diagnosis and must adhere to the defined safety protocol to enter the offices. </p> <p style="font-family:Times New Roman, Times, serif; font-size:10pt; text-align:justify; margin-top:11pt; margin-bottom:0pt; ">In the past several years, Cass has invested in sophisticated technology initiatives that enable employees to operate remotely with full system(s) access along with unified and transparent voice and electronic communications capabilities, ensuring seamless service delivery. The Company cannot predict when or how it will fully lift the actions put in place as part of the Business Continuity Plan, including work from home requirements and travel restrictions. Cass does not believe the work from home protocol has materially adversely impacted internal controls, financial reporting systems, or operations. </p>
