Dollar dips, Nikkei slugged by Toshiba selloff

By Wayne Cole SYDNEY (Reuters) - Asian shares were subdued on Thursday after Wall Street suffered a mild setback after weeks of gains, while a pullback in U.S. yields prompted year-end profit taking in the dollar. Japan's Nikkei shed 1.3 percent as the yen firmed and Toshiba Corp dived 16 percent after news of potential massive writedowns led to a downgrade of its credit ratings. MSCI's broadest index of Asia-Pacific shares outside Japan was last up 0.19 percent.
