Our portfolio of marketable securities is comprised of debt and equity securities that are classified as available for sale. Available for sale securities are presented on our consolidated balance sheets at fair value. Gains and losses resulting from the mark-to-market of these securities are included in “other comprehensive (loss) income.” Gains and losses are recognized in earnings only upon the sale of the securities and are recorded based on the weighted average cost of such securities.

In the six months ended June 30, 2012 and 2011, we sold certain marketable securities for aggregate proceeds of $58,460,000 and $19,301,000, resulting in net gains of $3,582,000 and $2,139,000, respectively, of which $3,582,000 and $48,000 were recognized in the three months ended June 30, 2012 and 2011.

We own 23,400,000 J.C. Penney common shares, or 11.0% of its outstanding common shares. Below are the details of our investment.

We own 18,584,010 common shares at an average economic cost of $25.76 per share, or $478,677,000 in the aggregate. As of June 30, 2012, these shares have an aggregate fair value of $433,193,000, based on J.C. Penney's closing share price of $23.31 per share. Unrealized gains and losses from the mark-to-market of these shares are included in “other comprehensive (loss) income.” The three and six months ended June 30, 2012 include $225,383,000 and $220,180,000, respectively, of unrealized losses. The three and six months ended June 30, 2011 include $25,611,000 of unrealized losses and $41,292,000 of unrealized gains, respectively.

We also own an economic interest in 4,815,990 common shares through a forward contract executed on October 7, 2010, at a weighted average strike price of $28.93 per share, or $139,348,000 in the aggregate. The contract may be settled, at our election, in cash or common shares, in whole or in part, at any time prior to October 9, 2012. The strike price per share increases at an annual rate of LIBOR plus 80 basis points. The contract is a derivative instrument that does not qualify for hedge accounting treatment.
