Sector-Specific Metrics: How Banks, REITs and Insurers Read Differently

Different figures in this article. Every other article in Group IV uses Wexford Instruments. Wexford is a manufacturer, and the three sectors here have statements that do not resemble a manufacturer's at all — so this article uses its own illustrative figures, clearly marked, and does not tie to the canonical company except for comparison.

For most businesses that framing works. For three large sectors it fails — not at the edges but at the centre — and understanding why reveals something about the standard toolkit: it was designed for a particular kind of company and quietly assumes it.

Banks: the balance sheet is the business

For a manufacturer, the balance sheet supports the operation. For a bank, it is the operation. Loans are the product and sit as assets; deposits are the raw material and sit as liabilities. A bank's income statement is largely a description of its balance sheet, which reverses the usual reading order.

What replaces the standard measures. Net interest margin — the spread between what is earned on assets and paid on funding — takes the place of gross margin. Loan-loss provisions and non-performing loans matter more than any operating expense, because credit losses are the main way banks fail. Capital ratios replace conventional leverage measures and are set by regulation rather than by management. And book value carries real meaning here, unlike at a manufacturer, because a bank's assets are mostly financial and carried near current value.

The structural fact that matters most is leverage. On the illustration below, a bank runs at 12.5 times assets to equity against Wexford's 1.96 — and at that leverage, losing 1% of the loan book costs 9% of equity. That is not a defect; it is what banking is. It does mean that ordinary leverage comparisons across the boundary are meaningless.

REITs: depreciation describes nothing

Property companies own buildings that are depreciated on the income statement while frequently appreciating in reality. Depreciation is the single largest expense and it may correspond to nothing that is happening.

So the sector reports funds from operations — net income with property depreciation added back and gains on sales removed — and adjusted funds from operations, which further deducts the maintenance spending buildings genuinely require. Net income is close to uninformative here, and the gap is not marginal: on the illustration, funds from operations are 3.2 times reported net income. Occupancy, lease expiry profiles, and net asset value complete the picture.

Insurers: paid before the cost is known

An insurer collects premiums now and pays claims later, sometimes decades later — so its profit depends on an estimate of costs that have not yet arrived. Reserving is the central judgement, and it is far larger than any accrual at a manufacturer.

The combined ratio — claims plus expenses as a percentage of premiums — is the sector's headline measure. Below 100% the underwriting itself made money; above 100% it lost money and the company relied on investment returns. And the premiums held between collection and payment are invested in the meantime, which is why an insurer can run at a small underwriting loss and remain profitable.
