Profit and Contingency Provision

Study guides: Exam FAM, Exam 5, Exam GI-101

Profit and Contingency Provision (Q_T) is the loading in the rate that, together with net investment and other income, provides an appropriate total after-tax return — the CAS Statement of Principles' definition of the underwriting profit and contingency provisions. The two halves answer two different risks: a charge for random variation from expected costs belongs in the total return consistent with the cost of capital, and so in the underwriting profit provision; a charge for systematic variation of the estimated costs from the expected costs belongs in the contingency provision.

\text{Rate} = \frac{\text{Pure Premium} + F}{1 - V - Q_T}

\text{Target Combined Ratio} = 1 - Q_T

  • Q_T is a target underwriting profit provision, not a target total profit. Total return also includes investment income on policyholder-supplied funds (the loss and unearned premium reserves) and on capital (whether to include the latter is disputed), so the actuary typically determines the underwriting profit needed to achieve the target total return after consideration of investment income.
  • Consequently Q_T is line-dependent. Long-tail lines hold reserves for years and earn substantial investment income on them, so they can support a low or even negative underwriting provision and still return the target on equity; short-tail lines have little float and need a positive one.
  • Standard derivations: the target return on equity approach solves for the Q_T that produces the required return given a premium-to-surplus ratio and an investment yield; discounted cash flow / internal rate of return models value the whole policy cash flow; the calendar-year investment income offset approach credits investment income directly against the provision.
  • The contingency element is the Statement of Principles' charge for systematic variation — the estimated costs differing from the expected costs. Random variation around expected costs, the long right tail of the loss distribution, is not what it covers: that risk is charged through the cost of capital in the underwriting profit provision.
  • The Statement of Principles asks that the contribution of net investment and other income be considered, and that the material assumptions and actuarial judgments of a ratemaking be documented and available for disclosure — so how investment income and the cost of capital were reflected belongs in the documentation, not just the selected Q_T.

The Provision in the Rate A line has a projected pure premium of \$250, fixed expenses of \$0, variable expenses of 30\% and a target underwriting profit provision of 5\%.

Compute the rate and verify the profit margin.

Answer

\begin{align*}
\text{Rate} &= \frac{\$250}{1 - 0.30 - 0.05} \\
&= \frac{\$250}{0.65} \\
&= \$384.62
\end{align*}

Decomposing:

\begin{align*}
\text{Losses} &= \$250.00 \quad (65.0\%) \\
\text{Variable expenses} &= 0.30 \times \$384.62 = \$115.39 \quad (30.0\%) \\
\text{Profit} &= 0.05 \times \$384.62 = \$19.23 \quad (5.0\%)
\end{align*}

The target combined ratio is 95\%: the insurer expects to spend \$0.95 of every premium dollar and keep \$0.05 as underwriting profit, before any investment income.

Deriving the Provision from a Target Return An insurer targets a 12\% after-tax return on equity. It writes at a premium-to-surplus ratio of 2:1. Reserves and unearned premium average 70\% of annual premium and earn 4\% after tax; surplus also earns 4\% after tax. The tax rate on underwriting profit is 21\%.

Derive the indicated underwriting profit provision.

Answer Work per \$1 of premium. Surplus is \$0.50 (from the 2:1 ratio).

Required after-tax income:

0.12 \times \$0.50 = \$0.060

Investment income already available (after tax):

\begin{align*}
\text{On policyholder funds} &= 0.70 \times 0.04 = \$0.028 \\
\text{On surplus} &= 0.50 \times 0.04 = \$0.020 \\[4pt]
\text{Total} &= \$0.048
\end{align*}

Shortfall to be earned from underwriting, after tax:

\$0.060 - \$0.048 = \$0.012

Grossing up for tax:

Q_T = \frac{\$0.012}{1 - 0.21} = \$0.0152 \approx 1.5\%

The indicated provision is about 1.5\% of premium — small, because this line's float and surplus are already producing most of the required return.

Change one assumption and the answer moves sharply: at a 1:1 premium-to-surplus ratio the required income doubles to \$0.120 while the investment income rises only to \$0.068, pushing Q_T to 0.052/0.79 = 6.6\%. That sensitivity to the capital assumption is why the assumptions behind the provision should be documented rather than asserted.
