TOKYO, May 16 (Reuters) - The Nikkei share average lost 1.1 percent on Wednesday as forecasts for profit declines at some of Japan's major banks and reports of flat bank lending in China chilled already tepid risk sentiment from fears that Greece could exit the euro. The Nikkei fell to 8,801.17, while the broader Topix index slipped 1.1 percent to 738.88.
