2012 Credit Facility

In March 2014, we entered into an amendment to the $1.6 billion credit facility entered into by the Company in November 2012, or the 2012 credit facility, which among other things, increased the term loan portion of the facility by $383.0 million to $783.0 million, decreased the interest-rate margin applicable to the term loan portion of the facility by 25 basis points and extended the maturity of the term loan portion of the facility from March 30, 2018 to June 30, 2019. In November 2014, we increased the term loan portion of the facility by $50.0 million to $833.0 million. As of December 31, 2014, the 2012 credit facility, as amended, consists of a $1.2 billion revolving credit facility, or the revolving credit facility, and an $833.0 million term loan, or the term loan facility. In January 2015, we entered into a second amended and restated credit agreement, which decreased the interest-rate margin and facility fee applicable to the revolving credit facility by 20 basis points and five basis points, respectively, and extended the maturity date of the revolving credit facility to March 29, 2019 with an as-of-right extension through March 29, 2020. We also have an option, subject to customary conditions, without the consent of existing lenders, to increase the capacity under the revolving credit facility to $1.5 billion at any time prior to the maturity date for the revolving credit facility, by obtaining additional commitments from our existing lenders and other financial institutions.

As of December 31, 2014, the 2012 credit facility bore interest at a spread over LIBOR ranging from (i) 100 basis points to 175 basis points for loans under the revolving credit facility and (ii) 95 basis points to 190 basis points for loans under the term loan facility, in each case based on the credit rating assigned to the senior unsecured long term indebtedness of ROP. At December 31, 2014, the applicable spread was 145 basis points for revolving credit facility and 140 basis points for the term loan facility. At December 31, 2014, the effective interest rate was 1.61% for the revolving credit facility and 1.67% for the term loan facility. We are required to pay quarterly in arrears a 15 to 35 basis point facility fee on the total commitments under the revolving credit facility based on the credit rating assigned to the senior unsecured long term indebtedness of ROP. As of December 31, 2014, the facility fee was 30 basis points. As of December 31, 2014, we had $113.2 million of outstanding letters of credit, $385.0 million drawn under the revolving credit facility and $833.0 million outstanding under the term loan facility, with total undrawn capacity of $701.8 million under the 2012 credit facility.

In connection with the amendment of the 2012 credit facility, we incurred debt origination and other loan costs of $3.0 million. We evaluated the modification pursuant to ASC 470 and determined that the terms of the amendment were not substantially different from the terms of the previous 2012 credit facility. As a result, these deferred costs and the unamortized balance of the costs previously incurred are amortized through the extended maturity date of the term loan facility.

The Company, the Operating Partnership and ROP are all borrowers jointly and severally obligated under the 2012 credit facility. None of our other subsidiaries are obligors under the 2012 credit facility.

The 2012 credit facility includes certain restrictions and covenants (see Restrictive Covenants below).

2011 Revolving Credit Facility

The 2012 credit facility replaced our $1.5 billion revolving credit facility, or the 2011 revolving credit facility, which was terminated concurrently with the entering into the 2012 credit facility. The 2011 revolving credit facility bore interest at a spread over LIBOR ranging from 100 basis points to 185 basis points, based on the credit rating assigned to the senior unsecured long-term indebtedness of ROP, and required to pay quarterly in arrears a 17.5 to 45 basis point facility fee on the total commitments under the 2011 revolving credit facility. The 2011 revolving credit facility included certain restrictions and covenants and, as of the time of the termination of the 2011 revolving credit facility and as of November 2012, we were in compliance with all such restrictions and covenants.

Restrictive Covenants

The terms of the 2012 credit facility, as amended, and certain of our senior unsecured notes include certain restrictions and covenants which may limit, among other things, our ability to pay dividends, make certain types of investments, incur additional indebtedness, incur liens and enter into negative pledge agreements and dispose of assets, and which require compliance with financial ratios relating to the minimum amount of tangible net worth, a maximum ratio of total indebtedness to total asset value, a minimum ratio of EBITDA to fixed charges, a maximum ratio of secured indebtedness to total asset value and a maximum ratio of unsecured indebtedness to unencumbered asset value. The dividend restriction referred to above provides that, we will not during any time when a default is continuing, make distributions with respect to common stock or other equity interests, except to enable the Company to continue to qualify as a REIT for Federal income tax purposes. As of December 31, 2014 and 2013, we were in compliance with all such covenants.

Junior Subordinate Deferrable Interest Debentures

In June 2005, the Company and the Operating Partnership issued $100.0 million in unsecured trust preferred securities through a newly formed trust, SL Green Capital Trust I, or the Trust, which is a wholly-owned subsidiary of the Operating Partnership. The securities mature in 2035 and bear interest at a fixed rate of 5.61% for the first ten years ending July 2015. Thereafter, the interest rate will float at 125 basis points over the three-month LIBOR. Interest payments may be deferred for a period of up to eight consecutive quarters if the Operating Partnership exercises its right to defer such payments. The Trust preferred securities are redeemable at the option of the Operating Partnership, in whole or in part, with no prepayment premium. We do not consolidate the Trust even though it is a variable interest entity as we are not the primary beneficiary. Because the Trust is not consolidated, we have recorded the debt on our consolidated balance sheets and the related payments are classified as interest expense.
