Financial Reporting Quality: Aggregate Accruals

Microsoft Excel

Earnings can be decomposed into cash and accrual components. The accrual component (aggregate accruals) has been found to have less persistence than the cash component, and therefore (1) earnings with higher accrual component are less persistent than earnings with smaller accrual component, all else equal; and (2) the cash component of earnings should receive a higher weighting evaluating company performance.

Balance-sheet-based accruals ratio = 100 × Balance-sheet-based aggregate accruals ÷ Avg. net operating assets
= 100 × 930 ÷ [(22,077 + 21,147) ÷ 2] = 4.30%

The financial trajectory from 2022 to 2026 is characterized by a steady expansion of the operating asset base contrasted with significant volatility and a subsequent decline in the balance-sheet-based accruals ratio. While net operating assets grew consistently, the reliance on accruals relative to those assets diminished over the latter half of the period.

Net Operating Assets Trend
An overall upward trend is observed in net operating assets, which rose from 17,783 million US dollars in 2022 to 22,077 million US dollars by 2026. Aside from a marginal decrease between 2022 and 2023, the operating asset base expanded steadily, reflecting a growth in the scale of operations.
Aggregate Accruals Volatility
Balance-sheet-based aggregate accruals demonstrated substantial instability between 2022 and 2024. A sharp decline from 3,337 million US dollars in 2022 to negative 69 million US dollars in 2023 was followed by a rebound to 2,159 million US dollars in 2024. However, a consistent downward pattern emerged after 2024, with accruals falling to 1,274 million US dollars in 2025 and 930 million US dollars in 2026.
Accruals Ratio and Reporting Quality
The balance-sheet-based accruals ratio mirrored the volatility of aggregate accruals, peaking at 20.71% in 2022 before dropping to -0.39% in 2023. Following a return to 11.49% in 2024, the ratio declined progressively to 6.21% in 2025 and 4.30% in 2026. This sustained reduction in the ratio indicates an improvement in financial reporting quality, as earnings became increasingly supported by cash flows rather than accounting accruals relative to the size of the operating assets.

An analysis of the financial reporting quality reveals a significant divergence between the growth of net operating assets and the trajectory of aggregate accruals over the observed five-year period. While the asset base has expanded, the reliance on accruals to drive reported earnings has diminished substantially, indicating a shift toward higher cash-flow alignment.

Net Operating Assets Trend
Net operating assets demonstrated a consistent upward trajectory after a marginal decline in 2023. Values rose from 17,783 million USD in August 2022 to 22,077 million USD by August 2026, representing a steady expansion of the operational asset base.
Aggregate Accruals Performance
Cash-flow-statement-based aggregate accruals experienced a sharp contraction, falling from a peak of 2,367 million USD in 2022 to 196 million USD in 2023. Following a slight increase to 437 million USD in 2024, the figures continued to decline, eventually turning negative at -213 million USD in 2026.
Accruals Ratio Interpretation
The accruals ratio reflects a marked improvement in earnings quality. The ratio dropped precipitously from 14.69% in 2022 to 1.10% in 2023. It remained low through 2025 (0.37%) before reaching -0.99% in 2026. This transition from a high positive ratio to a negative ratio suggests that reported earnings are increasingly supported by cash flows rather than accounting accruals.

The convergence of increasing net operating assets and decreasing aggregate accruals indicates a strengthening of financial reporting quality. The movement into negative territory for both aggregate accruals and the accruals ratio by 2026 suggests a conservative earnings profile where cash generation exceeds accrual-based recognition.
