Yahoo Japan Corp. said Tuesday it will conduct a two-for-one stock split Nov. 20 for stockholders of record as of Sept. 30.

Yahoo officials said the number of shares involved has not yet been decided because there is a plan to issue new shares prior to the split.

The operator of Japan's leading Internet portal said the company's outstanding shares numbered 942,403.08 and its capital stood at 6.178 billion yen as of Tuesday.
