ROTHSTEIN-YOUAKIM, Judge.

Robert Gunther, Jayne Gunther, and Highpoint Tower Technology, Inc., appeal a final summary judgment determining that the statute of limitations barred their claims against Morgan, Lewis & Bockius, LLP, for aiding and abetting fraud and breach of fiduciary duty and for civil

conspiracy to commit fraud and breach of fiduciary duty. They argue that the statute of limitations did not begin to run on their claims until the Internal Revenue Service first obtained a judgment against them. The trial court disagreed, and so do we. On this record, the "finality accrual rule," as extended in Kipnis v. Bayerische Hypo-Und Vereinsbank, AG, 202 So. 3d 859 (Fla. 2016), does not apply to the Gunthers' and Highpoint's claims.

Background The scheme

The Gunthers are the sole shareholders of Highpoint, which operated a communications tower business. In 1999, the Gunthers sold Highpoint's assets for $50 million.1 Because the capital gains on that sale were substantial, the Gunthers and Highpoint were faced with millions of dollars in tax liability, and so they searched for ways to reduce or eliminate their tax bill.

BDO Seidman, LLP (n/k/a BDO USA, LLP), an accounting firm with a dedicated tax advisory group, was then marketing an "investment strategy" to high-income individuals like the Gunthers. That strategy involved purchasing offsetting long and short options in the foreign currency markets and then transferring them to a partnership. While BDO claimed it was possible to make money on currency trades using this strategy, the real point was to manufacture tax losses for the partners through the use of a partnership structure, which losses could be claimed by the partners when the partnership was unwound.

1 We derive this factual background from the summary judgment

record, which we construe in the light most favorable to the Gunthers and Highpoint. See G & G In-Between Bridge Club Corp. v. Palm Plaza Assocs., 356 So. 3d 292, 297 (Fla. 2d DCA 2023).

As the Supreme Court noted in United States v. Woods, 571 U.S.

31, 35 (2013), "the alchemy at the heart of an offsetting-options tax shelter" is how the taxpayers "calculate[] the tax basis of their interests in the partnerships." "Tax basis is the amount used as the cost of an asset when computing how much its owner gained or lost for tax purposes when disposing of it." Id. (citing J. Downes & J. Goodman, Dictionary of Finance and Investment Terms 736 (2010)). "A partner's tax basis in a partnership interest . . . is tied to the value of any assets the partner contributed to acquire the interest." Id. at 35–36.

The Gunthers and Highpoint elected to proceed with BDO's strategy in late 1999. They paid approximately $1.3 million in "consulting" fees to an affiliate of Sentinel Capital, LLC, who acted as the "investment advisor." Sentinel set up Arbitrage Trading, LLC, as the partnership vehicle for the Gunthers and Highpoint. The partners included Sentinel, a Sentinel affiliate, a trust run by the Gunthers, and Highpoint. The Gunthers and Highpoint then purchased long euro call options through an account with AIG International, Inc., for a collective premium of approximately $21.5 million and simultaneously sold offsetting short euro call options to AIG for a collective premium of approximately $21.3 million. They then contributed those offsetting positions to Arbitrage Trading. But here's the rub. As to the options, the Gunthers and Highpoint only came out of pocket the spread between the premiums (so roughly the $200,000 difference between the premiums for the long and short euro call options). Then, before the end of 1999, the Gunthers and Highpoint withdrew from Arbitrage Trading, creating purported tax losses for the Gunthers and Highpoint of around $21.5 million (based above all on the full premium amount of the long options only, which amount the Gunthers and Highpoint never actually paid).

Arbitrage Trading, the Gunthers, and Highpoint, however, would not file their 1999 returns claiming those losses until late 2000.

In early 2000, meanwhile, some at BDO were beginning to question the legality of the strategy. The executives running BDO's "Tax Solutions" group (the tax executives), who reaped significant benefit from the strategy, knew that it was likely illegal. But they figured that if they could obtain an opinion from a major law firm downplaying the likelihood of illegality, they could quash the growing concern among others at BDO, continue to market the strategy to new clients, and encourage existing clients like the Gunthers to claim the purported tax benefits in their tax returns and in any subsequent disputes with the IRS.

To obtain that legal cover, the tax executives turned in part to Morgan Lewis. The attorneys that they consulted at that firm recognized immediately that the strategy was likely an illegal tax shelter. Morgan Lewis lawyers noted that the "tax solutions" were "too good to be true," were "dubious," and did not pass the " 'smell' test of experts." One Morgan Lewis attorney noted several "uglies," including "enormous losses and no apparent profit motive." Morgan Lewis commented in an early meeting with the tax executives that "someone wanting to make a [criminal] case could."

Then, in August 2000, the IRS issued a warning that tax shelters involving "transactions calling for the simultaneous purchase and sale of offsetting options which were then transferred to a partnership" could give rise to criminal liability. Morgan Lewis internally concluded that BDO's strategy was essentially identical to the tax shelters flagged in the IRS notice.

But as notes of a conference between the tax executives and a principal Morgan Lewis tax attorney demonstrate, the tax executives

wanted a whitewashed opinion with a preordained conclusion that was dismissive of any illegality or potential criminal liability. Morgan Lewis, together ultimately with another law firm, facilitated that report. Now able to tell their other BDO partners and BDO's board that BDO had nothing to worry about, the tax executives not only successfully encouraged BDO to continue marketing and implementing the strategy, but they also had the cover they needed to continue to assure clients such as the Gunthers that that strategy was legal.
