NEW YORK (Standard&Poor's) Feb. 11, 2015--NEW YORK (Standard&Poor's) Feb. 11, 2015--Standard&Poor's Ratings Services said today it assigned its 'B' issue-level rating to U.S.-based homebuilder KB Home's proposed $250 million senior unsecured notes due 2023. The recovery rating is '3', indicating our expectation for meaningful (50% to 70%) recovery in the event of a payment default. We expect the company to use the proceeds to retire $200 million of 6.25% senior notes due June 15, 2015, and for general corporate purposes. Following the retirement of the senior notes due in June 2015, the company will have no material debt maturities until Sept. 15, 2017. Our 'B' corporate credit rating and stable rating outlook on KB
