WASHINGTON/NEW YORK, June 30 (Reuters) - U.S. securities regulators are considering changing how companies are required to disclose stock options awarded to executives, people familiar with the Securities and Exchange Commission's thinking told Reuters on Tuesday.

At an SEC meeting on Wednesday, the commissioners also will propose giving investors a greater voice in setting executive pay at companies that were given taxpayer funds under the U.S. government's Troubled Asset Relief Program.

Among the possible changes is a revision to how companies value equity awards in the "summary compensation table" for top executives that they file with the commission each year.

The SEC is considering requiring companies to include the estimated value for stock options granted during the year, the people said. The sources requested anonymity because the proposal is still being crafted and may change.
