PALM BEACH, Fla. - After more than a year of attending finance events across the country, from California to Texas to New York, tonight marks Mitt Romney's final campaign fundraiser, an aide confirmed to ABC News.

The final event comes on the same day that the candidate's FEC filings were made public for October, showing that Romney raised $77.7 million in September and has more than $63 million in cash on hand.

To date, Romney has raised more than $361 million for his campaign compared with the President's $567 million, according to Bloomberg News.

Romney attended the final fundraiser at two different homes in the tony Palm Beach area, where driveways are often too long to spot the home's front doors, and where waterfront properties are the norm.

The final fundraiser was split between the homes of Dwight and Martha Schar and Wilbur and Hilary Ross.

Schar is a part-owner of the Washington Redskins and is the founder of NVR, a Fortune 500 homebuilding company. Ross is an investment banker.

It was at a Palm Beach fundraiser that Romney's now infamous 47 percent comments were secretly recorded during a finance event in May.

Romney's final finance event this evening is closed to the press, as were many of them during the campaign, leading to no final tally of the number of fundraisers Romney has attended in total. To be sure, Romney has likely attended hundreds since announcing his candidacy in June 2011.

With an evening fundraiser at the JW Marriott Marquis in Miami, Fla., Oct. 11, President Obama topped 222 re-election fundraisers since announcing his bid for a second term in April 2011, ABC News' Devin Dwyer reported.
