May 27 (Bloomberg) -- Steven Rattner, head of the U.S. Treasury Department’s automotive team, has a net worth of at least $188 million and held shares in an investment fund run by the majority owner of Chrysler LLC, according to his financial- disclosure statement.

Rattner, co-founder of Quadrangle Group LLC, also sold guarantees of as much as $15 million on a credit-default swaps index tied to the secured debt of 100 companies, including General Motors Corp.’s senior secured loans, the filing shows.

He reported holdings of between $500,000 and $1 million in Cerberus Institutional Partners LP Series 2. The fund is managed by Cerberus Capital Management LP, the parent of Auburn Hills, Michigan-based Chrysler. Cerberus Institutional Partners has invested in two auto-parts and equipment companies and a car-rental company, all privately owned. Rattner has since sold all those holdings, according to an official at the Treasury.

He was “required to comply with financial conflict-of- interest rules, including divestitures where needed, and he has done so fully,” said Jenni Engebretsen, a Treasury spokeswoman, who responded on Rattner’s behalf. The filing is for the period between Jan. 1, 2008, and Feb. 20, 2009.

Rattner, 56, has directed the Treasury’s auto team since February. Chrysler, which filed for bankruptcy protection on April 30, received $4 billion from the government in January. The company, the third-largest U.S. automaker, will get $500 million more from the Treasury’s Troubled Asset Relief Program, TARP’s special inspector general said in a report.

Quadrangle

Quadrangle, a New York-based private-equity firm that invests in media companies and distressed debt, paid Rattner $3.1 million, according to his disclosure forms.

He reported an overall net worth of between $188 million and $608 million. Government officials are required to disclose their net worth only within broad ranges. His minimum net worth is equal to about 27 percent of the $702.2 million market capitalization of General Motors today and about 20 percent of that of the New York-based New York Times Co., with a value of $948.8 million.

Rattner, a former New York Times reporter, started the media-acquisition group at Morgan Stanley, a New York-based investment bank, in 1984. He moved to what was then Lazard Freres & Co. in 1989. Rattner, along with Lazard executives Peter Ezersky, Joshua Steiner and David Tanner, started Quadrangle in 2000 after sketching out their plans in meetings at Rattner’s apartment on New York’s Fifth Avenue.

Rattner owned at least $105 million in various Quadrangle investments. He also reported holdings of between $500,000 and $1 million in Goldman Sachs Group Inc. stock, and less than $1,001 apiece in Bear Stearns Cos., Citigroup Inc., and Lehman Brothers Holdings Inc.

Airplane, Horse Farm

Rattner owns an airplane, valued between $5 million and $25 million, used in an air charter business; and a horse farm in North Salem, New York, valued at between $5 million and $25 million.

He held less than $1,001 in Dearborn, Michigan-based Ford Motor Co. in his family trust, according to the financial disclosure.

Rattner reported that he owed between $5 million and $25 million for the farm and the plane and has as an unsecured credit line of between $5 million and $25 million. He also reported owing between $5 million and $25 million in estimated tax payments for 2008, and as much as $50 million in various partnerships.

Executive Search Firm

The forms also show that a company associated with Rattner received more than $5,000 from Spencer Stuart, a closely held executive search firm with offices around the world.

General Motors interim Chairman Kent Kresa hired Spencer Stuart to help find new directors for the GM board. Treasury Department officials suggested that Kresa hire Spencer Stuart, the Wall Street Journal reported May 11, citing a person close to the matter. GM, which is receiving government aid, is based in Detroit. GM spokesman Greg Martin declined to comment. The automaker faces a June 1 deadline to avoid bankruptcy.

Jim Horton, a spokesman in New York for Spencer Stuart, declined to comment on the firm’s work for GM.

375 Events LLC

The payment listed on the disclosure is related to sponsorship of an annual conference run by a Quadrangle-owned entity named 375 Events LLC. Treasury’s Engebretsen said 375 Events is funded by a group of sponsors of which Spencer Stuart is one. Neither Quadrangle nor Rattner have an ownership interest in Spencer Stuart or any other relationship with them, Engebretsen said.

Rattner sold $3 million to $15 million in credit-default swaps to a unit of Goldman Sachs Group Inc. on the equally weighted index known as the Markit LCDX Series 10, according to the filing. The index includes the senior secured loans of 100 companies including GM and Ford, according to the filing.

An investor that sold such protection on the index would have to pay as much as $150,000 in the event of a company bankruptcy, less the value of the underlying loans.

Rattner received compensation of more than $5,000 apiece from New York Mayor Michael Bloomberg, his family trust and his family foundation. Bloomberg is the founder and majority owner of Bloomberg LP, the parent company of Bloomberg News. The disclosure form also says Rattner provided advisory services to Bloomberg LP valued in excess of $5,000.

Rattner and his wife, Maureen White, raised between $100,000 and $250,000 for Barack Obama’s presidential campaign.
