The following table presents the maturities of the Company's total fixed income securities as of March 31, 2013 (in millions):



	Amortized Cost		Gross Unrealized Gains		Gross Unrealized Losses			Estimated Fair Value

The Company had 134 and 98 investments in unrealized loss positions as of March 31, 2013 and December 31, 2012, respectively. The gross unrealized losses related to these investments were primarily due to changes in market interest rates and stock prices. The Company reviews its investments to identify and evaluate investments that have an indication of possible impairment. The Company aggregates its investments by category and length of time the securities have been in a continuous unrealized loss position to facilitate its evaluation. For the available-for-sale debt securities that have unrealized losses, the Company evaluates whether it (i) does not intend to sell any of these investments and (ii) it is not more likely than not that it will be required to sell any of these investments before recovery of the entire amortized cost basis. For available-for-sale equity securities that have unrealized losses, the Company evaluates whether there is an indication of other-than-temporary impairments. This determination is based on several factors, including the financial condition and near-term prospects of the issuer and the Company's intent and ability to hold the publicly-traded equity securities for a period of time sufficient to allow for any anticipated recovery in market value. During the three months ended March 31, 2013 and 2012, the Company did not recognize other-than-temporary impairments associated with these investments.

There were no material gross realized gains or losses from available-for-sale and trading securities during the three months ended March 31, 2013 and 2012. Realized gains and losses are determined based on the specific identification method.

Restricted Cash and Investments

The Company classifies cash and investments designated as available-for-sale securities as restricted cash and investments on its Condensed Consolidated Balance Sheets for: (i) amounts held in escrow accounts, as required by certain acquisitions completed between 2005 and 2013; (ii) the India Gratuity Trust and Israel Retirement Trust, which cover statutory severance obligations in the event of termination of any of the Company's India and Israel employees, respectively; and (iii) the Directors and Officers ("D&O") indemnification trust.

The following table summarizes the Company's cash and investments that are classified as restricted cash and investments in the Condensed Consolidated Balance Sheets (in millions):

	March 31, 2013		December 31, 2012
Restricted cash	$	1.9	$	0.8
Restricted investments	92.5		105.6
Total restricted cash and investments	$	94.4	$	106.4

Privately-Held Investments

As of March 31, 2013 and December 31, 2012, the carrying values of the Company’s privately-held investments of $39.2 million and $32.0 million, respectively, were included in other long-term assets in the Condensed Consolidated Balance Sheets.

The Company reviews its investments to identify and evaluate investments that have an indication of possible impairment. The Company adjusts its privately-held investments for any impairment if the fair value is less than the carrying value of the respective assets on an other-than-temporary basis.

During the three months ended March 31, 2012, the Company determined that certain privately-held investment were other-than-temporarily impaired, which resulted in impairment charges of $14.0 million and were recorded within other expense, net in the Condensed Consolidated Statements of Operations. There were no such charges during the three months ended March 31, 2013.
