The company uses the market approach technique to value its financial instruments and there were no changes in valuation techniques during 2010. The company's financial assets and liabilities carried at fair value are primarily comprised of investments in money market funds, mutual funds holding publicly traded securities, derivative contracts used to hedge the company's currency and interest rate risks and other investments in unit trusts and insurance contracts held as assets to satisfy outstanding retirement liabilities.

The fair value accounting guidance requires that assets and liabilities carried at fair value be classified and disclosed in one of the following three categories:

Level 1: Quoted market prices in active markets for identical assets or liabilities that the company has the ability to access.

Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data such as quoted prices, interest rates and yield curves.

Level 3: Inputs are unobservable data points that are not corroborated by market data.

The following tables present information about the company's financial assets and liabilities measured at fair value on a recurring basis as of December 31, 2010 and 2009:

Available-for-sale investments are carried at fair value and are included in the tables above. The aggregate market value, cost basis and gross unrealized gains and losses of available-for-sale investments by major security type are as follows:

(In millions)	Market Value		Cost Basis		Gross Unrealized Gains		Gross Unrealized Losses

2010
Mutual Fund and Unit Trust Investments	$	32.0	$	26.1	$	5.9	$	—
Auction Rate Securities		4.6		5.3		—		0.7

	$	36.6	$	31.4	$	5.9	$	0.7

2009
Mutual Fund and Unit Trust Investments	$	31.2	$	26.9	$	4.3	$	—
Auction Rate Securities		5.4		6.0		—		0.6

	$	36.6	$	32.9	$	4.3	$	0.6

The cost of available-for-sale investments that were sold was based on specific identification in determining realized gains and losses recorded in the accompanying statement of income. Gross realized gains and gross realized losses on the sale of available-for-sale investments were nominal in 2010, 2009 and 2008.

In addition to available-for-sale investments, the company had $4.3 million and $1.7 million of trading securities, consisting of debt and equity securities, at December 31, 2010 and 2009, respectively.

The company determines the fair value of its insurance contracts by obtaining the cash surrender value of the contracts from the issuer. The company determines the fair value of the auction rate securities by obtaining indications of value from brokers/dealers. During 2009, the company recorded in other expense, net, $0.3 million of impairment charge on the auction rate securities for declines in value deemed attributable to credit losses exceeding six to nine months duration and thus considered other-than-temporary. The company determines the fair value of acquisition-related contingent consideration based on assessment of the probability that the company would be required to make such future payment. Changes to the fair value are recorded in selling, general and administrative expense. The following tables provide a rollforward of the fair value, as determined by Level 3 inputs, of the auction rate securities and contingent consideration.

The notional amounts of derivative contracts outstanding totaled $1.78 billion and $1.24 billion at year-end 2010 and 2009, respectively. The fair value of such contracts is the estimated amount that the company would receive upon liquidation of the contracts, taking into account the change in currency exchange rates.
