MARKETABLE SECURITIES

NOTE B — MARKETABLE SECURITIES

The Company’s marketable securities are held in the custody of a single financial institution. To be considered for investment, securities must meet certain minimum requirements as to their credit ratings, time to maturity and other risk-related criteria as prescribed by the Company’s investment policies. The primary objective of these investments is the preservation of capital, with the secondary objectives of attaining higher yields than the Company earns on its cash and cash equivalents and maintaining a high degree of liquidity.

The Company’s investment portfolio, which is recorded at fair value, consisted of the following marketable securities at September 30, 2011 and 2010:
