DOJ probe targets four intermediaries in Mark Walter's insurance lending empire

The investigation

Federal prosecutors digging into Mark Walter's business empire are focused on four entities that acted as intermediaries between insurance companies he controlled and other businesses he also controlled, according to people familiar with the matter. Walter, the owner of the Los Angeles Dodgers and CEO of Guggenheim Partners, faces allegations that insurers he controlled lent to other parts of his investment empire without disclosing links to those loans. Both prosecutors and the Securities and Exchange Commission are examining whether the loans were properly disclosed. FBI agents confronted Walter when his Gulfstream jet touched down in Chicago, returning from British Columbia, where his stealthy purchases of farmland in a pristine valley had infuriated locals. Walter is now rushing a makeover of his empire as the DOJ probe intensifies.

Walter's Wall Street rise

Before amassing one of the biggest privately held sports and investment empires in the world, Walter was a little-known trader in an obscure market on Wall Street, far from the greed and glory of high-stakes corporate takeovers and audacious trades. He grew up on a farm in Iowa and studied accounting at Creighton University in Nebraska before spending years running Liberty Hampshire, a finance company specialising in bundling securities in the commercial paper marketplace that companies turn to for short-term cash. In that niche market, Walter became an expert in squeezing out extra profits by managing large pools of short-term debt securities, perfecting skills that would form the foundation of his rise on Wall Street and beyond.

Mark was always looking for arbitrage and inefficiencies.

The person added that Walter understood how to match assets and liabilities, referring to the complex task of managing interest rate risks while coordinating quickly maturing assets with new incoming interest payments.

Building Guggenheim

In the late 1990s, Walter and Liberty Hampshire were introduced to an heir of the Guggenheim fortune that bestows the eponymous Frank Lloyd Wright-built museum in New York City, marking the financier's break into the mainstream of finance. Walter and co-founders, including financier J Todd Morley and Peter Lawson-Johnston, a descendant of Solomon Guggenheim, formed Guggenheim Partners in 1999. The brokerage quickly became a giant on Wall Street, managing over $300bn in assets.

Walter's career accelerated during the 2008 financial crisis, when he directed Guggenheim into the sleepy but lucrative insurance marketplace, spotting an opportunity to take advantage of bargain valuations across the industry after the failure of industry giant AIG. Guggenheim acquired large insurers in Kansas, Delaware and elsewhere. Walter and his associate Todd Boehly spotted the opportunity to plough billions of dollars of policyholder liabilities into untraded assets that could earn high returns.

Broader implications

The investigation could further undermine confidence in a multitrillion-dollar private credit business that in the past decade has copied Walter's strategy of tying insurance to alternative assets. The approach of ploughing policyholder liabilities into higher-yielding untraded assets has been widely replicated across Wall Street. The probe's outcome could carry implications for the many firms that adopted similar structures, given the scale of the private credit market today.
