Changes in unrealized market appreciation or depreciation<br />

<strong>of</strong> Ñxed maturities were due primarily to Öuctuations<br />

in interest rates.<br />

Market Risk<br />

Market risk represents the potential for loss due to<br />

adverse changes in the fair value <strong>of</strong> Ñnancial instruments.<br />

Our primary exposure to market risks relates to our<br />

investment portfolio, which exposes the Corporation<br />

and its property and casualty subsidiaries to risks related<br />

to interest rates and, to a lesser extent, credit quality,<br />

prepayment, foreign currency exchange rates and equity<br />

prices. We also have exposure to market risks through<br />

our credit derivatives business and our debt obligations.<br />

Analytical tools and monitoring systems are in place to<br />

assess each <strong>of</strong> these elements <strong>of</strong> market risk.<br />

INVESTMENTS<br />

guidelines established by management and approved by<br />

the boards <strong>of</strong> directors.<br />

The main objectives in managing the investment portfo-<br />

lios <strong>of</strong> the Corporation and its property and casualty<br />

subsidiaries are to maximize after-tax investment income<br />

and total investment returns while minimizing credit<br />

risks in order to provide maximum support to the<br />

insurance underwriting operations. Investment strategies<br />

are developed based on many factors including underwriting<br />

results and our resulting tax position, regulatory<br />

requirements, Öuctuations in interest rates and consideration<br />

<strong>of</strong> other market risks. Investment decisions are<br />

centrally managed by investment pr<strong>of</strong>essionals based on<br />

Interest rate risk is the price sensitivity <strong>of</strong> a security that<br />

promises a Ñxed return to changes in interest rates.<br />

Changes in market interest rates directly aÅect the<br />

market value <strong>of</strong> our Ñxed income securities. We view<br />

the potential changes in price <strong>of</strong> our Ñxed income<br />

investments within the overall context <strong>of</strong> asset and<br />

liability management. Our actuaries estimate the payout<br />

pattern <strong>of</strong> our liabilities, primarily our property and<br />

casualty loss reserves, to determine their duration, which<br />

is the present value <strong>of</strong> the weighted average payments<br />

expressed in years. We set duration targets for our Ñxed<br />

income investment portfolios after consideration <strong>of</strong> the<br />

duration <strong>of</strong> these liabilities and other factors, which we<br />

believe mitigates the overall eÅect <strong>of</strong> interest rate risk for<br />

the Corporation and its property and casualty<br />

subsidiaries.<br />

The following table provides information about our Ñxed<br />

maturity investments which are sensitive to changes in<br />

interest rates. The table presents cash Öows <strong>of</strong> principal<br />

amounts and related weighted average interest rates by<br />

expected maturity dates at December 31, <strong>2001</strong> and<br />

2000. The cash Öows are based on the earlier <strong>of</strong> the call<br />

date or the maturity date or, for mortgage-backed<br />

securities, expected payment patterns. Actual cash Öows<br />

could diÅer from the expected amounts.<br />
