BOSTON -- American Tower Corporation (NYSE: AMT) announced today that it has entered into a new $500.0 million senior unsecured term loan credit facility.

The Company expects to receive net proceeds of approximately $498.5 million from the new term loan and will use approximately $450.0 million to repay certain existing indebtedness under the Company's continuing senior unsecured revolving credit facility and the remainder for general corporate purposes.
