The bond balance approximates its fair market value, therefore no realized or unrealized gains or losses have been recorded.   The primary objectives of the Companys investment portfolio are liquidity and safety of principal. Investments are made with the objective of achieving the highest rate of return consistent with these two objectives. The Companys investment policy limits investments to certain types of debt and money market instruments issued by institutions primarily with investment grade credit ratings and places restrictions on maturities and concentration by type and issuer.   The Company reviews its available-for-sale securities for other-than-temporary declines in fair value below their cost basis on a quarterly basis and whenever events or changes in circumstances indicate that the cost basis of an asset may not be recoverable. This evaluation is based on a number of factors including, the length of time and extent to which the fair value has been less than its cost basis and adverse conditions specifically related to the security including any changes to the rating of the security by a rating agency. As of July 31, 2013, the Company believes that the cost basis for its available-for-sale securities is recoverable in all material respects.falsefalsefalsenonnum:textBlockItemTypenaTabular disclosure of marketable securities.
