Treasury Secretary Tim Geithner is set to meet with "leading experts on executive compensation" Wednesday morning as the Obama administration mulls regulation on executive pay.

As the Obama administration reportedly considers executive compensation regulation extending beyond companies in which the government has invested, Geithner will sit down at 11 a.m. with top federal officials and unnamed experts, according to the Treasury.

Included in the meeting will be Geithner, Securities and Exchange Commission Chairwoman Mary Schapiro, Don Tarullo of the Federal Reserve, and what the agency termed "leading executive compensation experts."

The meeting may signal that the Obama administration is moving closer to proposing some concrete constraints on compensation structuring for executives and other top earners in the U.S. economy.

The group is supposed to face a pool spray early this afternoon as the meeting concludes.
