Bank and Other Notes Payable: | 11. Bank and Other Notes Payable: Bank and other notes payable consist of the following: Senior Notes: On March 16, 2007, the Company issued $950,000 in Senior Notes that matured on March 15, 2012. The Senior Notes bore interest at 3.25%, payable semiannually, were senior to unsecured debt of the Company and were guaranteed by the Operating Partnership. Prior to December 14, 2011, upon the occurrence of certain specified events, the Senior Notes were convertible at the option of the holder into cash, shares of the Company's common stock or a combination of cash and shares of the Company's common stock, at the election of the Company, at an initial conversion rate of 8.9702 shares per $1 principal amount. On or after December 15, 2011, the Senior Notes were convertible at any time prior to March 13, 2012. The conversion right was not exercised prior to the maturity date of the Senior Notes. During the years ended December 31, 2011 and 2010, the Company repurchased and retired $180,314 and $18,468, respectively, of the Senior Notes for $180,792 and $18,283, respectively, and recorded a loss on the early extinguishment of debt of $1,449 and $489, respectively. The repurchases were funded by borrowings under the Company's line of credit and/or from cash proceeds from the Company's April 2010 common stock offering. On March 15, 2012, the Company paid-off in full the $439,318 of Senior Notes then outstanding. The carrying value of the Senior Notes at December 31, 2011 was $437,788, which included an unamortized discount of $1,530. The unamortized discount was amortized into interest expense over the term of the Senior Notes in a manner that approximated the effective interest method. As of December 31, 2011, the effective interest rate was 5.41%. The fair value of the Senior Notes at December 31, 2011 was $437,788 based on the quoted market price on each date. Line of Credit: The Company had a $1,500,000 revolving line of credit that bore interest at LIBOR plus a spread of 0.75% to 1.10% that matured on April 25, 2011. On May 2, 2011, the Company obtained a new $1,500,000 revolving line of credit that bears interest at LIBOR plus a spread of 1.75% to 3.0% depending on the Company's overall leverage and matures on May 2, 2015 with a one-year extension option. This extension option is at the Company's discretion, subject to certain conditions, which the Company believes will be met. Based on the Company's current leverage levels, the borrowing rate on the new facility is LIBOR plus 2.0%. The line of credit can be expanded, depending on certain conditions, up to a total facility of $2,000,000 less the outstanding balance of the $125,000 unsecured term loan as described below. As of December 31, 2012 and 2011, borrowings under the line of credit were $675,000 and $290,000, respectively, at an average interest rate of 2.76% and 2.96%, respectively. The estimated fair value (Level 2 measurement) of the line of credit at December 31, 2012 and 2011 was $675,107 and $292,366, respectively, based on a present value model using a credit interest rate spread offered to the Company for comparable debt. Term Loan: On December 8, 2011, the Company obtained a $125,000 unsecured term loan under the line of credit that bears interest at LIBOR plus a spread of 1.95% to 3.20% depending on the Company's overall leverage and matures on December 8, 2018. Based on the Company's current leverage levels, the borrowing rate is LIBOR plus 2.20%. As of December 31, 2012 and 2011, the total interest rate was 2.57% and 2.42%, respectively. The estimated fair value (Level 2 measurement) of the term loan at December 31, 2012 and 2011 was $121,821 and $120,019, respectively, based on a present value model using a credit interest rate spread offered to the Company for comparable debt. Greeley Note: On July 27, 2006, concurrent with the sale of Greeley Mall, the Company provided marketable securities to replace Greeley Mall as collateral for the mortgage note payable on the property (See Note 7—Marketable Securities). As a result of this transaction, the mortgage note payable was reclassified to bank and other notes payable. This note bears interest at an effective rate of 6.34% and matures in September 2013. At December 31, 2012 and 2011, the Greeley Note had a balance outstanding of $24,027 and $24,848, respectively. The estimated fair value (Level 2 measurement) of the note at December 31, 2012 and 2011 was $24,685 and $26,510, respectively, based on current interest rates for comparable loans. The method for computing fair value was determined using a present value model and an interest rate that included a credit value adjustment based on the estimated value of the collateral for the underlying debt. As of December 31, 2012 and 2011, the Company was in compliance with all applicable financial loan covenants. The future maturities of bank and other notes payable are as follows:
2013 |  | $ | 24,027 |
2016 |  |  | 675,000 |
Thereafter |  |  | 125,000 |
|  | $ | 824,027 |
The future maturities reflected above reflect an extension option that the Company believes will be exercised.
