Management’s Discussion (Continued)
Equity Price Risk (Continued)
prefer to invest a meaningful amount in each investee. Consequently, equity investments are concentrated in relatively few
investees. At December 31, 2012, approximately 63% of the total fair value of equity investments was concentrated in five
investees.
We often hold equity investments for long periods of time so we are not troubled by short-term price volatility with respect
to our investments provided that the underlying business, economic and management characteristics of the investees remain
favorable. We strive to maintain above average levels of shareholder capital to provide a margin of safety against short-term
price volatility.
Market prices for equity securities are subject to fluctuation and consequently the amount realized in the subsequent sale of
an investment may significantly differ from the reported market value. Fluctuation in the market price of a security may result
from perceived changes in the underlying economic characteristics of the investee, the relative price of alternative investments
and general market conditions.
We are also subject to equity price risk with respect to our equity index put option contracts. While our ultimate potential
loss with respect to these contracts is determined from the movement of the underlying stock index between the contract
inception date and expiration date, fair values of these contracts are also affected by changes in other factors such as interest
rates, expected dividend rates and the remaining duration of the contract. These contracts expire between 2018 and 2026 and
may not be unilaterally settled before their respective expiration dates.
The following table summarizes our equity and other investments and derivative contract liabilities with equity price risk
as of December 31, 2012 and 2011. The effects of a hypothetical 30% increase and a 30% decrease in market prices as of those
dates are also shown. The selected 30% hypothetical changes do not reflect what could be considered the best or worst case
scenarios. Indeed, results could be far worse due both to the nature of equity markets and the aforementioned concentrations
existing in our equity investment portfolio. Dollar amounts are in millions.
