The Company recorded proceeds on the sales/maturities of investments of $42.1 million, $59.3 million and $24.9 million for the years ended May 31, 2012, 2011 and 2010, respectively. The Company recorded realized gains of $2.0 million, $4.9 million and $4.3 million for the years ended May 31, 2012, 2011 and 2010, respectively, which was included in other (income) expense.

The Company received $45.5 million face value zero coupon bonds in December 2010 from the Greek government as payment for an outstanding accounts receivable balance from calendar years 2007-2009 related to certain government sponsored institutions in a non-cash transaction. Upon receipt, the bonds had a fair value of $33.8 million, with maturity dates of one to three years. The bonds are designated as available-for-sale securities. The Company recorded realized losses of $20.1 million on the Greek bonds related to other-than-temporary impairment for the year ended May 31, 2012, which is included in other (income) expense with no other-than-temporary impairment recorded for the year ended May 31, 2011. The one year bonds matured in December 2011 and the Company received the full par value of approximately $8.4 million. On March 9, 2012 the Greek government finalized the private sector involvement in the Greek debt restructuring. All holders of Greek government bonds were required to exchange the existing bonds to new bonds. The new bonds have maturities ranging from 1 to 30 years. At May 31, 2012 the face value of the bonds was $15.7 million.

The Company reviews impairments to investment securities quarterly to determine if the impairment is “temporary” or “other-than-temporary.” The Company reviews several factors to determine whether losses are other-than-temporary, including but not limited to (1) the length of time each security was in an unrealized loss position, (2) the extent to which fair value was less than cost, (3) the financial condition and near-term prospects of the issuer, and (4) the Company’s intent and ability to hold each security for a period of time sufficient to allow for any anticipated recovery in fair value.

The Company offered a new deferred compensation plan as of January 1, 2011. The investments held by the Company mirror the investment selections of the participants. The investments are held in various equity securities and are considered trading with the realized gain and realized loss being recorded through other (income) expense.

Investment income on available-for-sale securities (included in other (income) expense) consists of the following:

(in millions)	Year Ended May 31, 2012		Year Ended May 31, 2011		Year Ended May 31, 2010
