What Is CECL in Banking and How Does It Work?

The Current Expected Credit Loss (CECL) standard, issued by the Financial Accounting Standards Board (FASB), changed how financial institutions account for credit losses. This standard requires entities to estimate and reserve for all expected credit losses over the entire life of financial assets at origination or acquisition. The effective date for large public companies was January 1, 2020, while other entities, including smaller reporting companies and private companies, began applying the standard for fiscal years starting after December 15, 2022.

From Incurred to Expected Loss Model

Before CECL, financial institutions operated under an “incurred loss” model, governed by Accounting Standards Codification (ASC) 450. Under this previous standard, losses were recognized only when considered “probable” and “estimable.” This meant institutions waited for a specific loss event, such as a missed payment or a decline in borrower creditworthiness, before setting aside reserves for potential losses.

This backward-looking approach often resulted in “too little, too late” recognition of credit losses, particularly during economic downturns. For example, if a loan’s performance deteriorated due to broader economic conditions, but no specific loss event occurred, reserves could not be established. This meant financial statements might not fully reflect true credit risk until well into a financial crisis.

CECL, codified under ASC 326, marked a significant shift to an “expected loss” model. This standard requires financial institutions to estimate and record an allowance for all expected credit losses over the entire contractual life of financial assets from origination or acquisition. This forward-looking approach means an allowance for potential future losses must be established immediately, even if a loan is performing well at inception.

The allowance for expected credit losses must consider past events, current conditions, and reasonable forecasts of future economic conditions. This proactive recognition aims to ensure financial statements provide a more timely and comprehensive view of credit risk exposure. The shift was largely a response to criticisms that the incurred loss model exacerbated financial crises by delaying the recognition of significant credit losses.

Key Components of a CECL Calculation

CECL applies to financial assets held at amortized cost. This includes typical banking assets such as loans held for investment, debt securities classified as held-to-maturity, and net investments in leases. Additionally, it covers off-balance-sheet credit exposures like loan commitments and financial guarantees.

The FASB did not mandate a single calculation methodology for CECL, providing institutions flexibility. This principles-based approach allows for various models as long as they result in a reasonable and supportable estimate of expected credit losses. The allowance for expected credit losses represents the portion of the amortized cost basis of a financial asset an entity does not expect to collect.

Common methodologies employed for CECL calculations include:
Historical loss rates, which use past loss experience as a starting point.
The discounted cash flow (DCF) method, which estimates future cash flows from a financial asset and discounts them to their present value.
Statistical models, such as probability of default (PD) multiplied by loss given default (LGD).
The roll-rate method, which analyzes how loans migrate through different delinquency stages to project future losses.

Key inputs for CECL estimations include historical information, current conditions, and reasonable forecasts of future economic conditions. Historical data, including past loss experience, provides a baseline. Current conditions, such as economic data and industry trends, adjust historical data. Forecasts of future economic conditions, like projected GDP growth or interest rate changes, influence future credit losses.

For periods beyond which an entity can make reasonable and supportable forecasts, the standard generally permits a reversion to historical loss information. To manage complexity, financial assets with similar risk characteristics are grouped together, a process known as pooling or segmentation. This allows for collective evaluation of expected credit losses for groups of assets rather than on an individual basis.

Impact on Financial Institutions

CECL implementation had a significant impact on financial institutions. Many experienced an initial increase in their allowance for credit losses (ACL) upon adoption. This required setting aside more capital as a day-one adjustment to retained earnings, reflecting the shift to estimating lifetime expected losses.

CECL also introduced increased earnings volatility. Changes in economic forecasts directly impact the provision for credit losses, leading to more fluctuation in reported net income compared to the previous incurred loss model. For example, during an economic downturn, institutions may need to recognize higher expected losses, impacting their reserves and overall financial performance.

Compliance with CECL’s data-intensive requirements necessitated investment in data infrastructure, analytical tools, and modeling capabilities. Institutions enhanced their ability to collect, process, and analyze extensive historical, current, and forward-looking data to support loss estimates. This often involved upgrading technology systems and developing more sophisticated models.

The standard also prompted operational and process changes within institutions. Internal controls, risk management practices, and financial reporting processes adapted to align with CECL’s requirements. This overhaul involved collaboration across various departments, including accounting, risk management, and IT.

CECL mandates extensive and detailed disclosures in financial statements. Institutions must provide greater transparency regarding credit quality, loss estimation methodologies, and underlying forecast assumptions. These disclosures aim to provide financial statement users a clearer understanding of the credit risk inherent in a portfolio.

The lifetime expected loss requirement under CECL influences lending decisions. The need to reserve for expected losses over the life of a loan at origination may lead banks to reassess how they price credit risk or structure loan products. The accounting standard encourages a more comprehensive upfront assessment of credit risk.
