KIEV, Jan. 28 - Standard & Poor's Ratings Services has lowered its long-term issuer credit and Ukraine national scale ratings on the Ukrainian city of Lviv to 'SD' (selective default) following the city's default on a coupon payment.

"We also lowered the senior unsecured debt ratings on a UAH 92 million bond tranche A, due July 20, 2012, and tranche B, due December 19, 2012, to 'D'. The city defaulted on the tranche A coupon," the agency said.
