With part of Nicholas Schorsch’s real estate empire fracturing into warring factions, a chunk of his fortune may depend on whether RCS Capital Corp. can distance itself from the accounting missteps at American Realty Capital Properties Inc.

RCS, an owner of broker-dealers that sell Schorsch's real estate investment products, called off the roughly $700 million acquisition of a unit of American Realty Capital Properties, or ARCP, after the seller reported intentionally concealed errors. ARCP sued last week, saying RCS improperly reneged. Schorsch, who holds about 29 percent of RCS, is chairman of both firms.

The dispute is pitting two companies against each other despite ties that include the same Manhattan address and a shared phone number. RCS is down 40 percent since ARCP’s Oct. 29 disclosure -- more than the 29 percent drop in the company that actually had the mistakes. Schorsch’s real estate empire is reliant on the money-raising capability of RCS, making protecting that business from fallout a priority, said Kevin Gannon, president of investment bank Robert A. Stanger & Co.

“RCS is more important to him,” said Gannon, whose Shrewsbury, New Jersey-based company compiles data on nontraded real estate investment trusts. “Its reputation and the ability to distribute American Realty Capital product is more important to the net worth of the group of guys than ARCP.”

ARCP’s chief financial officer and chief accounting officer resigned after a company probe found that an error made in first-quarter results was covered up in the second quarter. The move has sparked an FBI investigation and a review by the Securities and Exchange Commission, according to people with knowledge of the matter.

REIT Sales

It also is leading some brokers to halt sales tied to Schorsch’s AR Capital LLC, a separate company that’s the biggest sponsor in the $60 billion-plus industry of nontraded REITs, which are marketed to individual investors and depend heavily on the sponsor’s reputation. While ARCP is a landlord whose business is underpinned by more than 4,000 properties, RCS’s revenue is partly tied to sales of the AR Capital REITs.

RCS has sought to make it clear that it is separate from ARCP, saying in a Nov. 5 statement that its management teams are distinct and their independent directors don’t overlap. RCS reiterated that point on a Nov. 13 earnings conference call, where Chief Executive Officer Michael Weil said the company was confident in the integrity of its accounting after a review by an independent accounting firm.

Schorsch, 53, hasn’t been involved in discussions about the dropped deal to buy ARCP’s Cole Capital unit or the litigation, said Andrew G. Backman, managing director of investor relations and public relations for New York-based RCS.

Corporate Governance

“From a corporate-governance perspective, it’s a nightmare because he’s chairman of both litigants,” said Thomas Lys, a professor at the Kellogg School of Management at Northwestern University in Evanston, Illinois.

Schorsch and AR Capital co-founder William Kahane declined to comment for this story, said Tony DeFazio, a spokesman for AR Capital. Brian S. Block, who resigned as ARCP’s CFO, didn’t return multiple e-mails and phone calls. Andy Merrill, a spokesman for ARCP, didn’t return e-mails seeking comment.

Backman said in an e-mailed statement that “RCS Capital’s independent directors, which meet the independent director requirements of the New York Stock Exchange, approve related-party transactions and material transactions.”
