TOKYO, July 15 (Reuters) - Japan's Nikkei average was flat on on Wednesday, giving up earlier gains made on upbeat results from Goldman Sachs (GS.N: Quote, Profile, Research) and Intel (INTC.O: Quote, Profile, Research) after investors grew cautious ahead of more earnings in the United States and Japan.

The Bank of Japan voted unanimously to extend its corporate funding support measures beyond their planned expiry in September, and it kept interest rates on hold. The impact was limited as the moves were within expectations. [ID:nTKF106472] [ID:nT75063]
