The guaranteed investment contracts were established to pay for supplementary retirement benefits related to plans in Germany. The July 31, 2013 and July 31, 2012 consolidated balance sheets reflect related liabilities in the amounts of $65,428 and $57,363, respectively. Also included within retirement benefit assets are benefits protection trusts, with assets aggregating $71,990 and $77,935 as of July 31, 2013 and July 31, 2012, respectively. The trust was established for the primary purpose of satisfying certain supplemental post-employment benefit obligations in the U.S. for eligible executives in the event of a change of control of the Company. In addition to holding cash equivalents primarily to satisfy short-term cash requirements relating to benefit payments, the trust primarily invests in U.S. and Municipal government obligations, and debt obligations of corporations and financial institutions with high credit ratings. Contractual maturity dates of debt securities held by the trust range from 2013 to 2044. Such debt and equity securities are classified as available-for-sale and trading and aggregated $70,901 and $75,795 as of July 31, 2013 and July 31, 2012, respectively.
