“Accounting is not truth. It is a set of conventions. The investor's job is to understand what the numbers actually mean — which is often different from what they say.”
Why this matters.
Tillinghast's deep experience in small-cap investing, where accounting quality varies enormously and management teams sometimes aggressively exploit flexibility in accounting standards, produced a rigorous skepticism about reported financial statements. This passage captures a core skill that separates serious analysts from casual ones: the ability to translate accounting numbers into economic reality.
The conventions embedded in GAAP and IFRS create systematic gaps between reported earnings and actual economic performance. Goodwill amortization, revenue recognition timing, inventory valuation methods, stock-based compensation treatment, and off-balance-sheet financing are just a few of the areas where two companies with identical underlying economics can report substantially different numbers. Investors who compare reported EPS without adjusting for these differences are comparing numbers that may not be comparable.
For small-cap investors, the stakes are higher. Small companies often lack the internal finance teams and external auditor scrutiny that constrain larger companies. Management incentives — stock options, earnout structures, debt covenants tied to earnings — can create pressure to present the most favorable accounting interpretation of genuinely ambiguous transactions. Tillinghast's framework is to always ask: "What would this look like if I were running this business and wanted to show the best possible results within the rules?" Then assess how close the reported numbers appear to that maximum.
The antidote is cash flow. Free cash flow is significantly harder to manipulate than earnings, and Tillinghast consistently anchors his valuation work on cash generation rather than accounting income.
