In a Forbes article titled, "Subway’s Hidden Billions Revealed: How Its Founders Sliced Up A Fortune," trusts and estates partner David Slenn in Naples opined on how the estate of the company's late co-founder, Peter Buck, divided his wealth prior to announcing that the company was for sale.

Slenn, who represents high-net-worth individuals with the passage and preservation of wealth, reviewed a redacted copy of the will. Forbes wrote that Slenn observed that "Buck used tools 'consistent with somebody who has got high wealth and is trying to reduce his estate.' This includes grantor retained annuity trusts (GRATs) and his private charitable foundation, though Slenn emphasizes that private foundations are still 'subject to complex rules, such as those governing business holdings.' 'When you’re this wealthy, it’s a process. It’s not a one and done,' explains Slenn. 'It’s a process to keep reducing that estate.'"
