Romney worth between $190m and $250m, campaign says

The former Massachusetts governor has never released his tax returns, which would offer a fuller picture of his fortune, and has declined requests to do so this year.

Romney, who was criticized earlier this year for telling a group of voters that he was “unemployed,’’ earned nearly $114,000 from being on the board of Marriott International.

In the past year, Romney also received more than $374,000 in fees for nine speeches, including from some financial firms that he has sought to protect from more government regulations. For those speaking engagements, he was paid in a range from $11,475 to speak at Claremont McKenna College in Claremont, Calf., to $68,000 to speak at the National Franchisee Association in Las Vegas.

He was also was paid speaking fees by Barclays Bank, GoldenTree Asset Management, HP Healthcare Services, and Quest Educational Foundation. A Get Motivated Seminar, via satellite link in Boston, yielded $29,750.

“He has occasionally received compensation for speeches, and those have been disclosed in accordance with the law,’’ said Gail Gitcho, the Romney campaign’s communications director.

His wife, Ann Romney, owns horses in California worth between $250,001 and $500,000, according to the forms. She has promoted the use of horseback riding as a therapeutic way of coping with multiple sclerosis, from which she suffers. The horses she owns compete and earn prizes, according to Gitcho, so they are required to disclose Romney’s share of the company that owns them.

The Romneys also have investments in a wide range of areas, including consumer staples such as electronics and office supplies, large oil companies, and financial, health care, and telecommunications companies. His stock portfolio includes investments in Ford Motor Co., McDonald’s, Microsoft, General Electric, and Exxon Mobil.
