Marketable Securities
Deferred Compensation Plan Assets

Assets held in the trust associated with the NQDC Plan consist of money market shares, publicly traded equity securities, mutual funds and fixed income securities. Except for the money market shares, we account for these assets as trading securities, with gains or losses reported as Loss (gain) on deferred compensation plan securities in our consolidated statements of income. Loss (gains) from these assets is offset by the compensation expense (benefit) associated with our deferred compensation plan obligations. Therefore, gains or losses associated with the NQDC Plan assets do not impact our income before income taxes, net income, or cash balances.

Investment (loss) income  from our NQDC plan assets for 2011, 2010 and 2009 was comprised of the following:
