...HIGHTSTOWN (S&P Global Ratings) Feb. 28, 2018--S&P Global Ratings said today that it assigned its 'A' senior debt rating to The Travelers Cos. Inc.'s (NYSE:TRV) proposed $500 million 30-year senior debt issuance. Travelers intends to use the proceeds from this offering to retire $500 million of 5.80% senior notes maturing on May 15, 2018, so we expect no material change in financial leverage or fixed-charge coverage metrics. We view the group's financial flexibility as strong and expect financial leverage of about 20% and fixed-charge coverage above 10x in 2018, assuming normalized catastrophe losses contributing around five percentage points to the company's loss ratio.
