Dec 14 - Standard & Poor's Ratings Services said today that its issue-level rating on Crown Castle Operating Co.'s secured credit facilities remains unchanged at 'B+', following the company's upsizing of its revolving credit facility to $1.5 billion from $1 billion through an amendment to the credit agreement. However, we revised the recovery rating on the credit facilities to '4' from '3', indicating average (30% to 50%) recovery prospects in the event of a payment default. The revision primarily reflects the larger amount of secured debt at this entity, which results in a higher claim in a default scenario, coupled with less residual value from indirect subsidiary CC Holdings GS V LLC following its recent addition of secured debt which is structurally senior to the Crown Castle Operating Co. secured debt.
