Pleasanton-based Workday, which provides human resource software for businesses, plans to raise up to $400 million in an initial public offering of its Class A common stock, it was reported this week.

Reuters news service in July reported that the Pleasanton business software company was on track for the largest market debut since the botched debut by Facebook chilled demand for U.S. IPOs.

Reuters reported that Workday, backed by Amazon.com CEO Jeff Bezos and founded by David Duffield and other veterans of PeopleSoft, was said to have confidentially filed for an IPO in July under the new "JOBS" Act, which lets companies keep financial details contained in IPO documents private for longer.

In a preliminary prospectus with the U.S. Securities and Exchange Commission, the company listed Morgan Stanley and Goldman Sachs & Co as lead underwriters to the offering, Reuters reported, although the filing did not reveal how many shares the company planned to sell or their expected price.

Workday, which has its headquarters on Stoneridge Mall Road, intends to list its Class A common stock under the symbol "WDAY", but has not revealed the exchange on which it will list the shares.
