LONDON, March 27 - Moody's Investors Service has downgraded to Ca from Caa3 the corporate family rating and to Ca-PD from Caa3-PD the probability of default rating of DTEK ENERGY B.V. Moody's has also downgraded to Ca from Caa3 the senior unsecured bond ratings of DTEK Finance B.V. and DTEK Finance Plc, fully owned
finance subsidiaries of DTEK.

The outlook on all ratings remains negative.

The rating action reflects Moody's view that DTEK's default is “likely, given its stressed liquidity position." The rating action follows Moody's decision, on 24 March 2015, to (1) downgrade the Government of Ukraine's sovereign (government bond) rating to Ca from Caa3 with a negative outlook, and (2) lower the country's foreign-currency bond country ceiling to Caa3 from Caa2.
