The Company is exposed to foreign currency, interest rate, and securities price risks. A portion of these risks is hedged, but fluctuations could impact the Company’s results of operations and financial position. The Company hedges the exposure of accounts receivable and a portion of anticipated revenue to foreign currency fluctuations, primarily with option contracts. The Company monitors its foreign currency exposures daily to maximize the overall effectiveness of its foreign currency hedge positions. Principal currencies hedged include the Euro, Japanese yen, British pound, and Canadian dollar. Fixed income securities are subject to interest rate risk. The portfolio is diversified and consists primarily of investment grade securities to minimize credit risk. The Company routinely uses options to hedge its exposure to interest rate risk in the event of a catastrophic increase in interest rates. Many securities held in the Company’s equity and other investments portfolio are subject to price risk. The Company uses options to hedge its price risk on certain highly volatile equity securities.

The Company uses a value-at-risk (VAR) model to estimate and quantify its market risks. The VAR model is not intended to represent actual losses in fair value, but is used as a risk estimation and management tool. Assumptions applied to the VAR model at June 30, 2000 and June 30, 2001 include the following: normal market conditions; Monte Carlo modeling with 10,000 simulated market price paths; a 97.5% confidence interval; and a 20-day estimated loss in fair value for each market risk category. Accordingly, 97.5% of the time the estimated 20-day loss in fair value would be nominal for foreign currency denominated investments and accounts receivable at June 30, 2000 and June 30, 2001, and would not exceed $211 million and $363 million at June 30, 2000 and June 30, 2001 for interest-sensitive investments or $1.02 billion and $520 million at June 30, 2000 and June 30, 2001 for equity securities.
