Cash And Cash Equivalents [Abstract] |
Cash and Cash Equivalents | NOTE 5 – CASH AND CASH EQUIVALENTS The Company holds cash on deposit in excess of federally insured limits and has liquid mutual fund investments at Bank of America (the “Bank”). Management does not believe that the risks associated with keeping deposits in excess of federal deposit limits or holding investments in liquid mutual funds represent material risks. The Company considers all liquid investments with original maturities of three months or less at the time of purchase to be cash equivalents. At January 31, 2014, a significant portion of the balance of cash and cash equivalents was invested in a high-quality money market fund with at least 80% of its net assets invested in U.S. Treasury obligations and repurchase agreements secured by U.S. Treasury obligations. The fund is sponsored by an investment division of the Bank. The amount of cash and cash equivalents in the consolidated balance sheet as of January 31, 2014 included cash held within the consolidated joint venture entities that were formed during the current year. Such cash, which amounted to approximately $117.7 million as of January 31, 2014, will be used for activities of those construction joint ventures including future distributions to joint venture partners.
