Mark Walter Probe Puts Wall Street's Insurance-Private Credit Machine Under DoJ Scrutiny
An ongoing federal investigation into billionaire Mark Walter's business empire is raising alarm bells about Wall Street's use of insurance capital to finance private credit and other illiquid investments.
Bloomberg reported that Walter's TWG Global holding company said in a filing that it will wind down its exposure to affiliated businesses by up to $6.5 billion after the transactions drew scrutiny from federal investigators. This comes after the Department of Justice homed in on loans that should've been marked as affiliated transactions.
Walter's TWG Global holding company will buy up to $6.5 billion of affiliated assets from Delaware Life Insurance Co. in exchange for an equal amount of unaffiliated investments. Clear Spring Life and Annuity Co., another TWG-controlled insurer, separately reduced related-party transactions by $90 million.
The moves begin unwinding more than $20 billion of loans and investments that the insurers acknowledged should have been classified as affiliated transactions.
"Tripping over these requirements can constitute fraud," said Derek Reisfield, co-founder and former chairman of MarketWatch, as well as a former McKinsey consultant, who was quoted by The New York Post.
Reisfield said that heavy exposure to businesses connected to an insurer's owner poses a very high risk.
"The risk is that concentrated loans to related parties go south, and the insurance companies and their policyholders can't be made whole," Reisfield said, adding, "It's bad risk management and leaves the companies vulnerable."
Last week, Walter agreed to sell the Los Angeles Lakers to Josh Kushner and Bob Iger at a record $12.5 billion valuation, and earlier this week, a report stated that he is mulling over selling his stake in Chelsea Football Club to the majority owner, Clearlake Capital.
Insurance companies are allowed to do business with related parties, but such dealings must be disclosed and properly labeled to ensure that owners do not put their interests ahead of those of policyholders.
The investigation into Walter's empire is a major wake-up call about Wall Street's use of insurance capital to finance private credit and other illiquid investments.
Walter was one of the earliest adopters of the strategy of acquiring insurers and investing their long-term policyholder capital in higher-yielding private assets. A number of other asset managers, including Apollo, KKR, and Brookfield, have followed suit by building out insurance operations. Private-capital firms now manage more than $1 trillion of insurance assets.
"We have always acted in good faith, and insinuations that we have in any way attempted to circumvent our obligations are simply false," a TWG spokesman told The Wall Street Journal.
More problems: Walter, CEO of Guggenheim Partners, saw a financing entity tied to the investment firm report a sharp decline in second-quarter earnings, driven by the delayed recognition of advisory fees. The disclosure sent the entity's term loan tumbling below 80 cents on the dollar.
To sum up, the affiliated transactions were not inherently illegal, provided they had regulatory approval. That appears to be where the process broke down in Walter's case.
Talk about a turn of events. So Walter possibly built his empire by using a majority of capital from the insurance companies he controls. This violates insurance laws as the float is owed back to policy holders in the future. It must be diversified and safe. By using this… https://t.co/UWmFqr74wz

More concerning, however, is that deeper scrutiny has raised questions about the quality of the loans, the underlying borrowers, and the use of shell entities to channel financing into Walter-linked companies.
