At December 31, 2011 Newman Engineering's Liabilities include the following:

1. $10 million of 9% bonds were issued for $10million on May 31, 1988. The bonds marture on May 31, 2022, but bondholders have the option of calling (demanding payment on) the bonds on May 31, 2012. However the option to call is not expected to be exercised, given prevailing market conditions.

2. $14 million of 8% notes are due on May 31, 2015. A debt covenant requires Newman to maintain current assets at least equal to 175% of its current liabilities.

3. $7 million of 11% bonds were issued for $7 million on Augues 31, 1978. The bonds mature on July 31, 2012. Sufficient cash is expected to be available to retire the bonds at maturity.
