Nov 7 - OVERVIEW -- U.S. based chemical producer Celanese US Holdings LLC is issuing $500 million in senior unsecured notes due 2022. -- We assigned a 'BB' issue rating and '4' recovery rating to Celanese's proposed $500 million notes due 2022. -- We raised the issue rating on the existing senior unsecured notes to 'BB' from 'BB-' and revised the recovery rating to '4' from '5'. -- At the same time, we affirmed the 'BB' corporate credit and senior secured debt ratings on the company. -- The positive outlook reflects our opinion that, if operating performance remains strong and management continues to pursue a disciplined financial policy, we could raise the ratings modestly. NEW YORK (Standard & Poor's) Nov. 7, 2012--Standard & Poor's Ratings Services said today that it assigned its 'BB' issue rating and '4' recovery rating to Celanese's proposed $500 million notes due 2022. We also affirmed the 'BB' corporate credit rating on the company, as well as the 'BBB-' rating on the senior secured notes. We are maintaining our '1' recovery rating for the senior secured debt obligations, indicating our expectation of a very high (90% to 100%) recovery in the event of payment default. Also, we raised our rating on the senior unsecured notes to 'BB' and revised our recovery rating for both tranches of the unsecured notes to '4' from '5', indicating our expectation of an average (30% to 50%) recovery in the event of payment default. "The company will use proceeds from the notes issuance to repay a portion of the outstanding term loans under the company's senior credit facilities, and to make a $100 million contribution to Celanese's U.S. pension plan," said credit analyst Liley Mehta. "The ratings on Celanese US Holdings LLC, a subsidiary of Celanese Corp., reflect our assessment of the company's business risk profile as 'satisfactory' and a financial risk profile we view as 'significant'." The positive outlook reflects the company's above-par credit metrics, and our expectation of continued earnings growth over the next couple of years. Given its ongoing product innovation, geographic diversity, and efforts to boost productivity, we believe that Celanese can maintain its strong internal cash generation. We do not expect the company to make significant share repurchases or large acquisitions. We could raise the long-term ratings by one notch during the next several quarters if earnings and cash flow continue to increase, so that Celanese can preserve an FFO-to-total debt of 25% to 30% on a sustained basis. This could happen if the firm maintains debt near current levels while achieving annual top-line growth of 5% to 10% and EBITDA margins improving by 100 to 200 basis points from current levels. On the other hand, we could revise the outlook to stable if FFO-to-total debt declines to less than 20% as a result of weaker end-market demand, greater-than-expected shareholder-friendly activity, or any large debt-financed acquisitions.
