WASHINGTON REAL ESTATE INVESTMENT TRUST AMENDS AND EXTENDS CREDIT FACILITY

Washington Real Estate Investment Trust (WRIT) (NYSE: WRE) has amended one of its two unsecured credit facilities, increasing its size from $75 million to $100 million. An accordion feature allows WRIT to increase the facility to $200 million, subject to additional lender commitment. The new facility matures June 25, 2015, with a one-year extension option, bears interest at a rate of LIBOR plus a margin of 107.5 basis points based on WRIT’s current credit rating, and eliminates the requirement for guarantees from WRIT’s subsidiaries under certain circumstances.

SunTrust Bank is administrative agent and lender, and SunTrust Robinson Humphrey, Inc. is sole lead arranger and bookrunner for the facility.

“We are fortunate to have a strong, long-standing relationship with SunTrust Bank. Expanding this line from $75 million to $100 million and extending the maturity for 3 years adds to our already strong liquidity position. Combining our two lines of credit, WRIT now has a total capacity of $500 million. When considering the current balance on the lines, we still have enough capacity to refinance all of our outstanding maturities through 2014,” said William T. Camp, Executive Vice President and Chief Financial Officer of WRIT.

WRIT is a self-administered, self-managed, equity real estate investment trust investing in income-producing properties in the greater Washington metro region. WRIT owns a diversified portfolio of 72 properties totaling approximately 9 million square feet of commercial space and 2,540 residential units, and land held for development. These 72 properties consist of 27 office properties, 18 medical office properties, 16 retail centers and 11 multifamily properties. WRIT shares are publicly traded on the New York Stock Exchange (NYSE:WRE).
