NEW YORK (CNNMoney.com) -- Consumer electronics chain CompUSA's Mexican parent Grupo Carso is looking to put the company up for sale, according to a report published Wednesday.

Citing sources familiar with the matter, the Dallas Morning News reported that the Mexican conglomerate, which is controlled by billionaire Carlos Slim Helú, has asked Credit Suisse to quietly approach people who might have an interest in buying the company.

The paper said Roman Ross, CompUSA's new CEO, declined to comment on any sale.

"CompUSA is owned by Grupo Carso and it, like all other companies, is always looking at its portfolio and always evaluating what is best for a company," the paper quoted him as saying.

The 230-store chain posted its strongest operating results in a decade in 2005, but it wasn't able to keep up the momentum and needs additional capital to remodel and build new stores, the company said.

CompUSA went public in 1991 and subsequently underwent rapid expansion. By the mid- to late 1990s, it struggled with lower PC prices and increased competition from chains like Best Buy (Charts) and Circuit City (Charts), the report said.

In 2000, after a string of losses, CompUSA was taken private by companies owned by Helú. Last year, CompUSA posted sales of $4.6 billion.

The paper said Slim Helú's Mexico office couldn't be reached for comment.
