China's Tsinghua Holdings Co. has disclosed an unspecified investment in Marvell Technology Group Ltd., a Silicon Valley chip maker that recently replaced its leadership team in the wake of an accounting investigation and other problems.

Tsinghua Holdings reported the investment in a terse filing with the Federal Trade Commission, which is required under antitrust laws for transactions beyond a certain size. The FTC's threshold for reporting proposed mergers and acquisitions subject to antitrust enforcement is $78.2 million.

Companies that acquire a stake of more than 5% in publicly traded U.S. companies are required to file a disclosure with the Securities and Exchange Commission. Tsinghua Holdings has not done so; its representatives could not be reached.

A spokesman for Marvell said it did not know the size of the Tsinghua Holdings investment. "As far as we are concerned, they are a shareholder for investment purposes," he said, declining additional comment.

The FTC filing is the latest sign of interest in the U.S. semiconductor industry by investors in China, where government officials have been prodding companies to build a domestic industry to reduce a reliance on foreign-made chips.

Tsinghua Holdings, a Chinese state-owned company affiliated with Tsinghua University, has been among the most active investors. One of the company's affiliates, Tsinghua Unigroup Ltd., according to people familiar with the matter, last summer considered a $23 billion deal to buy Micron Technology Inc. but decided not to proceed amid signs that the deal would be blocked by U.S. regulators.

In February, a Tsinghua Unigroup unit backed out of a $3.78 billion deal to purchase 15% of disk drive maker Western Digital Corp., citing a decision by an intergovernmental group called the Committee on Foreign Investment in the U.S., or called CFIUS, to investigate the transaction on national security grounds.

In April, Tsinghua Unigroup disclosed a 6% stake in Lattice Semiconductor Corp. that it said it acquired in open-market stock transactions for investment purposes only. It has increased that stake to 8.65%, according to a May 6 filing with the Securities and Exchange Commission.

Lawyers who have worked with CFIUS say it typically does not review transactions that do not result in an investor gaining a board seat or otherwise take a controlling position in a target company. Lattice representatives have declined to comment.

Marvell, based in Santa Clara, Calif., is a 20-year-old company known for chips used in disk drives and networking. In early April, the company's board fired Chief Executive Sehat Sutardja and President Weili Dai, the husband-and-wife team that founded the company.

Timothy Arcuri, an analyst with Cowen & Co., has predicted that a management change would pave the way for a sale of some or all Marvell. He expressed doubts in an interview on Friday that U.S. regulators would approve the Chinese purchase of all of Marvell, but a partial sale might be allowed.

"This thing is absolutely ripe for China to come in," he said.

The firing of Marvell's longtime leaders, who remain directors, followed an accounting investigation by a board audit committee that identified "tone at the top" problems, including significant management pressure on sales and finance personnel to meet revenue targets.

Marvell later named a slate of new directors backed by activist investor Starboard Value LP, which took a 6.7% stake in Marvell. Richard Hill, an industry veteran who is former chief executive of Novellus Systems Inc., was named chairman. The company has launched a search for a permanent chief executive.
