Global Revolving Credit Facility

 

On November 3, 2011, the Operating Partnership replaced its corporate and Asia Pacific revolving credit facilities with an expanded revolving credit facility, which we refer to as the global revolving credit facility, increasing its total capacity to $1.5 billion from $850 million. The global revolving credit facility has an accordion feature that would enable us to increase the borrowing capacity of the credit facility to $2.25 billion, subject to the receipt of lender commitments. On August 10, 2012, we increased the aggregate commitments under our global revolving credit facility from $1.5 billion to $1.8 billion, pursuant to the partial exercise of the accordion feature.  The renewed facility matures in November 2015, with a one-year extension option. The interest rate for borrowings under the expanded facility equals the applicable index plus a margin which is based on the credit rating of our long-term debt and is currently 125 basis points. An annual facility fee on the total commitment amount of the facility, based on the credit rating of our long-term debt and currently 25 basis points, is payable quarterly. Funds may be drawn in U.S., Canadian, Singapore, Australian and Hong Kong dollars, as well as Euro, Pound Sterling, Swiss Franc and Japanese yen denominations. As of December 31, 2012, borrowings under the global revolving credit facility bore interest at a blended rate of  1.47% (U.S.), 1.75% (GBP), 1.36% (Euros), 1.56% (Singapore Dollars), 4.42% (Australian Dollars) and 1.53% (Hong Kong Dollars), which are based on 1-month LIBOR,  1-month GBP LIBOR,  1-month EURIBOR,1-month SIBOR,  1-month BBR and 1-month HIBOR, respectively, plus a margin of 1.25%. The facility also bore a blended rate of 3.50% (USD) which is based on U.S. Prime Rate plus a margin of 0.25%.We have used and intend to use available borrowings under the global revolving credit facility to acquire additional properties, fund development opportunities and to provide for working capital and other corporate purposes, including potentially for the repurchase, redemption or retirement of outstanding debt or preferred equity securities. As of December 31, 2012, we have capitalized approximately $11.2 million of financing costs related to the global revolving credit facility. As of December 31, 2012, approximately $723.7 million was drawn under this facility and $33.7 million of letters of credit were issued.

The global revolving credit facility contains various restrictive covenants, including limitations on our ability to incur additional indebtedness, make certain investments or merge with another company, and requirements to maintain financial coverage ratios, including with respect to unencumbered assets. In addition, the global revolving credit facility restricts Digital Realty Trust, Inc. from making distributions to its stockholders, or redeeming or otherwise repurchasing shares of its capital stock, after the occurrence and during the continuance of an event of default, except in limited circumstances including as necessary to enable Digital Realty Trust, Inc. to maintain its qualification as a REIT and to minimize the payment of income or excise tax. As of December 31, 2012, we were in compliance with all of such covenants.  

Unsecured Term Loan

On April 17, 2012, we closed a new $750.0 million senior unsecured multi-currency term loan facility. The new facility matures on April 16, 2017. Interest rates are based on our senior unsecured debt ratings and are currently 145 basis points over the applicable index for floating rate advances. Funds may be drawn in U.S, Singapore and Australian dollars, as well as Euro and Pound Sterling denominations with the option to add Hong Kong dollars and Yen upon an accordion exercise, subject to the receipt of lender commitments. We had the ability to delay draw up to $250.0 million for up to 90 days from the date of closing. As of June 30, 2012, we had drawn approximately $525 million of the available facility based on exchange rates in effect at the time of each draw.  An additional $225 million was drawn against the facility during July 2012 based on exchange rates in effect at the time of the draws.   Based on exchange rates in effect at December 31, 2012, the balance outstanding is approximately $757.8 million. We have used borrowings under the term loan for acquisitions, repayment of indebtedness, development, working capital and general corporate purposes. The covenants under this loan are consistent with our global revolving credit facility. As of December 31, 2012, we have capitalized approximately $5.3 million of financing costs related to the unsecured term loan.

 

Unsecured Senior Notes

Prudential Shelf Facility

On January 20, 2010, the Operating Partnership closed the sale of $100.0 million aggregate principal amount of its senior unsecured term notes to Prudential Investment Management, Inc. and certain of its affiliates, or, collectively, Prudential, pursuant to a Note Purchase and Private Shelf Agreement, which we refer to as the Prudential shelf facility. The notes were issued in two series referred to as the series D and series E notes. The series D notes have a principal amount of $50.0 million, an interest-only rate of 4.57% per annum and a five-year maturity, and the series E notes have a principal amount of $50.0 million, an interest-only rate of 5.73% per annum and a seven-year maturity. On February 3, 2010, the Operating Partnership closed the sale of an additional $17.0 million aggregate principal amount of its senior unsecured term notes, which we refer to as the series F notes, to Prudential pursuant to the Prudential shelf facility. The series F notes have an interest-only rate of 4.50% per annum and a five-year maturity. We used the proceeds of the series D, series E and series F notes to fund acquisitions, to temporarily repay borrowings under our corporate revolving credit facility, to fund working capital and for general corporate purposes. The sale of the series A ($25.0 million), series B ($33.0 million) and series C ($25.0 million) were completed in July 2008, November 2008 and January 2009, respectively. We may prepay the notes of any series, in whole or in part, at any time at a price equal to the principal amount and accrued interest of the notes being prepaid, plus a make-whole provision. On December 8, 2010, the Operating Partnership and Prudential entered into an amendment to the Note Purchase and Private Shelf Agreement, increasing the capacity of the Prudential shelf facility from $200.0 million to $250.0 million. Our ability to make additional issuances of notes under the Prudential shelf facility expired on July 24, 2011, with $50.0 million remaining unissued under the shelf facility. On July 25, 2011, we repaid the $25.0 million of 7.0% Series A unsecured notes under the Prudential shelf facility at maturity. As of December 31, 2012 and 2011, there was $175.0 million of unsecured senior notes outstanding.

 

On November 3, 2011, concurrent with the entry into the global revolving credit facility, the Operating Partnership and Digital Realty Trust, Inc. and the other subsidiary guarantors set forth therein entered into an Amended and Restated Note Purchase and Private Shelf Agreement with Prudential to conform the restrictive and financial covenants of the original Prudential shelf facility that apply to the outstanding Series B, C, D, E and F Notes under the facility to those in the global revolving credit facility described above and, subject to the completion of specified conditions, to authorize the potential issuance and sale of up to $50.0 million of additional senior unsecured fixed-rate term notes. The Prudential shelf facility contains restrictive covenants that are identical to those in our global revolving credit facility.

Senior Notes

4.500% Notes due 2015

On July 8, 2010, the Operating Partnership issued $375.0 million aggregate principal amount of notes, maturing on July 15, 2015 with an interest rate of 4.50% per annum (the 2015 Notes). The purchase price paid by the initial purchasers was 99.697% of the principal amount. The 2015 Notes are general unsecured senior obligations of the Operating Partnership, rank equally in right of payment with all other senior unsecured indebtedness of the Operating Partnership and are fully and unconditionally guaranteed by Digital Realty Trust, Inc. Interest on the 2015 Notes is payable on January 15 and July 15 of each year, beginning on January 15, 2011. The net proceeds from the offering after deducting the original issue discount of approximately $1.1 million and underwriting commissions and expenses of approximately $3.1 million was approximately $370.8 million.

The indenture governing the 2015 Notes contains certain covenants, including (1) a leverage ratio not to exceed 60%, (2) a secured debt leverage ratio not to exceed 40% and (3) an interest coverage ratio of greater than 1.50, and also requires us to maintain total unencumbered assets of not less than 150% of the aggregate principal amount of unsecured debt. At December 31, 2012, we were in compliance with each of these financial covenants.

We entered into a registration rights agreement whereby the Operating Partnership agreed to conduct an offer to exchange the 2015 Notes for a new series of publicly registered notes with substantially identical terms. If the Operating Partnership did not fulfill certain of its obligations under the registration rights agreement, it would have been required to pay liquidated damages to the holders of the 2015 Notes. No separate contingent obligation was recorded as no liquidated damages became probable. We filed a registration statement with the U.S. Securities and Exchange Commission in October 2010 in connection with the exchange offer, which was declared effective in December 2010. We completed the exchange offer on January 19, 2011.

Exchangeable Senior Debentures

5.50% Exchangeable Senior Debentures due 2029

On April 20, 2009, the Operating Partnership issued $266.4 million of its 5.50% exchangeable senior debentures due April 15, 2029 (the 2029 Debentures). Costs incurred to issue the 2029 Debentures were approximately $7.8 million. These costs are being amortized over a period of five years, which represents the estimated term of the 2029 Debentures, and are included in deferred financing costs, net in the consolidated balance sheet. The 2029 Debentures are general unsecured senior obligations of the Operating Partnership, rank equally in right of payment with all other senior unsecured indebtedness of the Operating Partnership and are fully and unconditionally guaranteed by Digital Realty Trust, Inc.

Interest is payable on October 15 and April 15 of each year beginning October 15, 2009 until the maturity date of April 15, 2029. The 2029 Debentures bear interest at 5.50% per annum and may be exchanged for shares of Digital Realty Trust, Inc. common stock at an exchange rate that was initially 23.2558 shares per $1,000 principal amount of 2029 Debentures. The exchange rate on the 2029 Debentures is subject to adjustment for certain events, including, but not limited to, certain dividends on Digital Realty Trust, Inc. common stock in excess of $0.33 per share per quarter (the “reference dividend”). Effective December 12, 2012, the exchange rate has been adjusted to 24.7390 shares per $1,000 principal amount of 2029 Debentures as a result of the aggregate dividends in excess of the reference dividend that Digital Realty Trust, Inc. declared and paid on its common stock beginning with the quarter ended September 30, 2012 and through the quarter ended December 31, 2012. Due to the fact that the exchange feature for the 2029 Debentures must be settled in the common stock of Digital Realty Trust, Inc., accounting guidance on convertible debt instruments that requires the principal amount to be settled in cash upon conversion does not apply.
