NEW YORK (Standard&Poor's) May 21, 2014--Standard&Poor's Ratings Services said today that it has assigned its 'A+' debt rating to intermediary holding company ACE INA Holdings Inc.'s proposed $700 million senior notes due 2024. The senior notes are fully and unconditionally guaranteed by Switzerland-based ultimate parent ACE Ltd. (ACE). ACE intends to use the proceeds of the issuance to repay, at maturity, $700 million of 2.6% senior notes due in November 2015. We expect the company's financial leverage to remain conservative at less than 20% and fixed-charge coverage to be more than 8x during the next two years.
