Financing Arrangements	F. Financing Arrangements Collateralized Borrowings On August 16, 2005, the Park Creek Metropolitan District (the “District”) issued $58,000,000 Junior Subordinated Limited Property Tax Supported Revenue Bonds, Series 2005 (the “Junior Subordinated Bonds”). The Junior Subordinated Bonds initially were to pay a variable rate of interest. Upon issuance, the Junior Subordinated Bonds were purchased by a third party and the sales proceeds were deposited with a trustee pursuant to the terms of the Series 2005 Investment Agreement. Under the terms of the Series 2005 Investment Agreement, after March 1, 2006, the District may elect to withdraw funds from the trustee for reimbursement for certain qualified infrastructure and interest expenditures (“Qualifying Expenditures”). In the event that funds from the trustee are used for Qualifying Expenditures, a corresponding amount of the Junior Subordinated Bonds converts to an 8.5% fixed rate and matures in December 2037 (“Converted Bonds”). On August 16, 2005, Stapleton Land, LLC, a consolidated subsidiary, entered into a Forward Delivery Placement Agreement (“FDA”) whereby Stapleton Land, LLC was entitled and obligated to purchase the converted fixed rate Junior Subordinated Bonds through June 2, 2008. The District withdrew $58,000,000 of funds from the trustee for reimbursement of certain Qualifying Expenditures by June 2, 2008 and the Junior Subordinated Bonds became Converted Bonds. The Converted Bonds were acquired by Stapleton Land, LLC under the terms of the FDA. Stapleton Land, LLC immediately transferred the Converted Bonds to investment banks and the Company simultaneously entered into a total rate of return swap (“TRS”) with a notional amount of $58,000,000. The Company receives a fixed rate of 8.5% and pays the Security Industry and Financial Markets Association (“SIFMA”) rate plus a spread on the TRS related to the Converted Bonds. The Company determined that the sale of the Converted Bonds to the investment banks and simultaneous execution of the TRS did not surrender control; therefore, the Converted Bonds have been recorded as a secured borrowing. Prior to July 31, 2011, consolidated subsidiaries of the Company purchased $23,000,000 of the Converted Bonds from the investment banks. Simultaneous to each purchase, a corresponding amount of a related TRS was terminated and the corresponding secured borrowing was removed from the Consolidated Balance Sheets. On May 12, 2011, the District refinanced $42,000,000 of the outstanding $58,000,000 Junior Subordinated Bonds. The Company received $23,000,000 of the refinancing proceeds as repayment of Converted Bonds held by its consolidated subsidiaries and the investment banks received the remaining $19,000,000 of refinancing proceeds which simultaneously terminated a corresponding amount of the related TRS and corresponding secured borrowing. The fair value of the Converted Bonds recorded in other assets was $16,000,000 and $58,000,000 at July 31 and January 31, 2011, respectively. The outstanding TRS contracts on the $16,000,000 and $35,000,000 of secured borrowings related to the Converted Bonds at July 31 and January 31, 2011, respectively, were supported by collateral consisting primarily of certain notes receivable owned by the Company aggregating $6,154,000. The Company recorded net interest income of $251,000 and $674,000 related to the TRS for the three and six months ended July 31, 2011, respectively, and $503,000 and $1,025,000 for the three and six months ended July 31, 2010, respectively. Other Financing Arrangements A consolidated subsidiary of the Company has committed to fund $24,500,000 to the District to be used for certain infrastructure projects and has funded $22,183,000 of this commitment as of July 31, 2011. In addition, in June 2009, the consolidated subsidiary committed to fund $10,000,000 to the City of Denver and certain of its entities to be used to fund additional infrastructure projects and has funded $8,198,000 of this commitment as of July 31, 2011.

Prior to July 31, 2011, consolidated subsidiaries of the Company purchased $23,000,000 of the Converted Bonds from the investment banks. Simultaneous to each purchase, a corresponding amount of a related TRS was terminated and the corresponding secured borrowing was removed from the Consolidated Balance Sheets.
