Investments

(4)  We have an investment policy approved by the Board of Directors that governs the quality, acceptability and dollar concentration of our investments.  The investment policy allows for investments in government and federal agency securities, commercial paper, repurchase agreements, bank certificates of deposit and money market funds.  Investments are comprised of marketable securities and consist primarily of commercial paper, asset-backed and mortgage-backed notes and bank certificates of deposits with original maturities beyond three months.  All marketable securities and corporate bonds are held in our name at two major financial institutions that hold custody of the investments.  All of our investments are held-to-maturity investments as we have the positive intent and ability to hold until maturity.  These securities are recorded at amortized cost.

The amortized cost and unrealized gain or loss of our investments at June 30, 2013 and March 31, 2013 were:
