Regulators moved Tuesday to require companies to provide far greater detail about executives’ pay and perks in an effort to bring more openness to an area that has provoked investor anger.

The five-member Securities and Exchange Commission voted unanimously to propose the biggest changes in rules governing disclosure of executives’ compensation since 1992. The proposal could be adopted by the SEC sometime after a 60-day public comment period.

Publicly traded companies for the first time would be required to furnish tables in annual filings showing the total yearly compensation for their chairmen, chief financial officers and the next three highest-paid executives.
