American Tower Corporation (NYSE: AMT) announced today that it has entered into a new unsecured revolving credit facility, having upsized the facility from $1 billion to $1.5 billion. The new credit facility includes a $1 billion sublimit for multicurrency borrowings, a $200 million sublimit for letters of credit, and a $50 million sublimit for swing line loans. In addition, the new facility allows American Tower to borrow up to an aggregate additional $500 million from lenders that elect to make such loans available, upon the satisfaction of certain conditions. At closing, American Tower used cash on hand to pay related fees under its existing $1.0 billion unsecured revolving credit facility entered into in April 2011, and subsequently terminated this facility. The new credit facility has a term of five years, maturing on June 28, 2018. As a result of this refinancing and American Tower’s recent upgrade from Fitch, the current interest rate declined from 1.850% to 1.250% plus LIBOR on the drawn portion and the commitment fee on the undrawn portion declined from 0.350% to 0.150%. The new facility does not require amortization of payments and may be paid prior to maturity in whole or in part at American Tower’s option without penalty or premium. The new facility allows American Tower to use borrowings for working capital needs, finance acquisitions and other general corporate purposes of American Tower and its subsidiaries, including, without limitation, to refinance or repurchase other indebtedness and to repurchase American Tower’s equity securities, in each case without additional lender approval.
