KIEV, Aug. 28 - Investors would only accept proposals on the restructuring of debt on eurobonds issued by Naftogaz Ukrayiny if the government issues sovereign guarantees on the debt, Carl Philipp R. Thomas, a partner at the Luxembourg-based Aequi-Libria consulting firm, told Interfax.

Thomas said his firm is not opposed to the restructuring in theory and could begin considering proposals if sovereign guarantees are issued.
