Assessing Bank Earnings Quality Through Net Income and Operating Cash Flow Matching: A Case Study of Bank of America

Abstract

Although net income is the standard profitability measure, it offers limited insight into earnings quality in the absence of the underlying cash flow support for reported earnings. This limitation is particularly acute for large banks, which require ongoing liquidity to support lending, trading and other commitments. This study conducts a case study diagnostic analysis that first measures the Cash Flow from Operations/Net Income (CFO/NI) ratio, then decomposes the gap using the indirect method and examines the reason behind, subsequently evaluates credit risk indicators relative to those of peer banks. The study finds that Bank of America's 2025 CFO/NI ratio was roughly 0.41, with shortfall predominantly explained by negative operating cash flow adjustments associated with trading and derivatives assets/liabilities and other assets. The provision for credit losses was positive noncash adjustment rather than a significant driver of the CFO reduction and remained largely aligned with realized credit losses. These findings indicate that the observed mismatch is more consistent with bank-specific balance-sheet and capital-markets activity than with a broad deterioration in underlying earnings quality or clear evidence of earnings management. These findings illustrate the analytical value of combining the CFO/NI ratio with indirect cash flow reconciliation and credit-risk validation in a case-based assessment of large-bank earnings quality.
