NEW YORK (Standard&Poor's) Feb. 21, 2012--Standard&Poor's Ratings Services said today that it is assigning a 'B' rating to Pittsburgh-based NEP/NCP Holdco Inc.'s $530 million term loan after the company announced they are repricing and adding an incremental $60 million to their $470 million first-lien term loan. The company plans to use the proceeds to repay a portion of its second-lien term loan. Pro forma for the transaction, NEP will have $530 million outstanding under its first-lien term loan and $80 million outstanding under its second-lien term loan. The transaction does not materially change debt leverage and reduces annual interest expense by approximately $5 million (or 13%). Our rating on NEP/NCP Holdco Inc. reflects our expectation that
