Work through the annual statement schedules and exhibits (Underwriting and Investment Exhibit, Schedule F, Schedule P, Statutory Page 14, 5-Year Historical Data), the Insurance Expense Exhibit, and the Statement of Actuarial Opinion, carrying out the calculations they support and using them to assess an insurer's condition.

A regulator opens an annual statement and asks one question: is this insurer solvent, and are its reserves reasonable? Every schedule below is a tool for answering it, and each supports a specific calculation you must be able to run cold.

The U&IE reconciles premium, losses, expenses, and investment income into statutory income. It restates the income statement in actuarial detail. Part 1 earns premium, Part 2 develops incurred losses, Part 3 assigns expenses, and the investment parts add net investment gain.

The core output is the combined ratio. Loss and LAE ratios use earned premium in the denominator. The underwriting expense ratio uses written premium, because acquisition costs are incurred when the policy is written, not as it earns.

$$\text{Combined} = \frac{\text{Incurred Loss}}{\text{Earned Prem}} + \frac{\text{Incurred LAE}}{\text{Earned Prem}} + \frac{\text{U/W Expense}}{\text{Written Prem}}$$

TRAP: Mixing denominators. Losses and LAE go over earned premium; underwriting expenses go over written premium. Using earned premium for expenses understates the ratio in a growing book.

Common mistakes

• Dividing underwriting expenses by earned premium. Acquisition expense is incurred at writing, so the combined ratio divides underwriting expense by written premium, not earned. Using earned inflates apparent profitability in a growing book.
• Charging the full unauthorized recoverable to the provision. Only the unsecured portion counts. If $10,000,000 is recoverable and $7,000,000 is collateralized, the unsecured piece is $3,000,000, not $10,000,000, and the two 20% charges for overdue and disputed balances are then added on top.
• Running the slow-pay screen on an unauthorized reinsurer, or applying the slow-paying charge to every authorized one. The screen sorts authorized reinsurers only: an unauthorized reinsurer carries its unsecured balance plus 20% of undisputed paid balances over 90 days plus 20% of all disputed amounts, whatever its payment record.

Bottom line

• The Underwriting and Investment Exhibit builds statutory underwriting gain; combined ratio = loss ratio + LAE ratio + underwriting expense ratio, with expenses divided by WRITTEN premium.
• Schedule F computes the provision for reinsurance, a surplus penalty for unauthorized recoverables (the unsecured balance plus 20% of undisputed paid balances over 90 days plus 20% of all disputed amounts) and for overdue and disputed balances from authorized reinsurers...
• Schedule P is the loss and LAE development database by line and accident year; it feeds the one-year and two-year reserve development tests measured against surplus.
• Statutory Page 14 reports premium, losses, and expenses by state for premium-tax and market analysis.

Exam shortcut

For any combined-ratio question, split the denominator instantly: losses and LAE over earned premium, expenses over written premium. If the two premium figures differ, the problem is testing exactly that distinction. For Schedule F, classify the reinsurer first. Unauthorized: unsecured recoverable plus 20% of undisputed paid balances over 90 days plus 20% of all disputed amounts, capped at the total recoverable, with no slow-pay screen. Authorized: run the slow-pay ratio.
