The Weekend the Number Changed

The appraisal was not high enough. Everything that followed began there.

The proposed refinancing of the Lake Las Vegas development totaled $540 million, and the participating funds—whose claims would later pass to Claymore Holdings, an affiliate of Highland Capital Management—were contributing $250 million. In April 2007, an analysis of the sprawling residential project outside Las Vegas valued the property at roughly $513 million, less than the loan the appraisal was supposed to support. That figure threatened the transaction before it began. A loan secured by collateral worth less than the debt would be difficult to market.

Over a single weekend, the appraisal was revised until it presented values as high as $891 million—nearly $380 million above the earlier analysis. The projected sell-out period accelerated. Assumptions concerning view premiums, golf-course revenue, investment income, and discounted cash flows changed, each in the direction the financing required. The completed document was distributed to prospective lenders as the independent, as-is appraisal the transaction demanded.

The number had not risen on its own. It reflected a series of decisions about what to include, what to assume, and what conclusion the document would support.

This is the terrain of Lisa S. Tsai’s practice: the space between a professional conclusion and the choices that produced it.

The Authoritative Surface

Financial wrongdoing rarely announces itself. More often, it arrives through documents that appear authoritative: an appraisal bearing the letterhead of a respected firm, advice presented as professional judgment, or a fiduciary decision accompanied by an explanation that seems complete.

The institution points to the contract, the report, the committee, or the market and presents the resulting loss as the natural product of an impersonal process. Responsibility is dispersed among documents, professionals, and decision-making bodies until the outcome begins to look as though no one quite chose it.

A plaintiffs’ lawyer must reconstruct what took place beneath that surface before the official account hardens into accepted fact.

Tsai—co-founder and managing partner of the national trial boutique Reid Collins & Tsai—represents plaintiffs in complex commercial disputes involving financial fraud, professional negligence, legal malpractice, fiduciary breach, and corporate misconduct. Her clients include investment funds, founders, bankruptcy trustees, companies, and individuals. The circumstances vary, but the structure of the dispute is often familiar. The defendant controls the documents, the professional machinery, and the explanation through which the loss is supposed to be understood.

Her method is to rebuild the case before that explanation becomes the case.

Before the Complaint

Tsai’s cases often begin months before anything is filed.

At Reid Collins, the work is deliberately front-loaded. The lawyers gather the public filings, transaction documents, and other records that can lawfully be assembled. They retain forensic accountants, valuation experts, and industry specialists when the matter requires them. They reconstruct the governing transactions and test potential legal theories against the available evidence. The objective is not merely to determine whether a claim can be pleaded. It is to identify what the case actually is, what the defense is likely to say, and which facts will ultimately decide it.

The preparation is especially important when a plaintiffs’ boutique faces a bank, accounting firm, corporation, or major law practice capable of filling discovery and motion practice with large legal teams. Institutional defendants can use scale as a form of pressure. Every unresolved issue consumes time, every unnecessary theory expands the battlefield, and an undisciplined record can bury the central conduct beneath years of procedure.

Tsai has described the practical answer in direct terms: being outmanned is not the same as being outgunned. Her teams may spend months developing a case before filing so that, once litigation formally begins, they already understand the documents, the likely defenses, and the factual questions that cannot be avoided. The theory is narrowed to what the evidence can carry; marginal claims that merely enlarge the target are discarded.

The advantage is one of position. A plaintiff who has mastered the decisive record before filing is less vulnerable to a defendant’s attempt to redefine what the documents show. The complaint arrives as the product of an investigation rather than an opening request for one. The theory begins with evidence rather than expectation.

That discipline also shapes which disputes become lawsuits at all. Some of Tsai’s engagements have resolved after extensive pre-suit analysis and negotiation, without a complaint ever reaching a docket. For a firm that shares materially in the cost and risk of its litigation, the decision not to file after a serious investigation reflects the same judgment required to carry a strong case through trial.

The Number Put on Trial

The Lake Las Vegas litigation subjected that method to an unusually demanding test.

Credit Suisse had arranged the refinancing of the development. The participating funds’ commitment was conditioned on an independent appraisal that complied with federal banking requirements and valued the collateral as it actually stood. Credit Suisse retained the appraiser and became deeply involved in obtaining the document that emerged from that weekend of revision.

Then the market collapsed, and the development defaulted. The property once appraised at $891 million was later valued at $23 million.

The ensuing dispute threatened to become unmanageable. It encompassed lending agreements, appraisal standards, federal regulations, reliance disclaimers, competing valuation experts, a disintegrating real-estate market, causation, and damages. Each subject offered a way to divert attention from the central sequence of events and dissolve the case into a technical seminar on valuation methodology.

Tsai’s task, helping lead the trial team alongside firm co-founder William T. Reid IV, was to return the case to that sequence. What value did the original analysis produce? Why was that value unacceptable? Which assumptions changed, and who asked for the changes? What did the lender know when the appraisal was distributed?

The record supplied the answers. The initial analysis valued the property below the loan it was meant to support, causing concern within Credit Suisse. The appraisal was then revised through assumptions that raised the represented value. The trial court later identified defects throughout the document—an accelerated absorption period, unsupported revenues, improper discounting, and the absence of the independence the appraisal was supposed to provide.

The strategy was to put the number itself on trial: to present the appraisal not as an autonomous professional product, but as evidence of choices made by identifiable people for an identifiable transaction.

In 2014, a Dallas County jury found by clear and convincing evidence that Credit Suisse had fraudulently induced the investment and awarded $40 million on that claim. Sitting in equity on a parallel claim, the trial court entered judgment against the bank totaling approximately $287.5 million.

Several rounds of appellate litigation followed. The Texas Supreme Court left the jury’s fraud finding intact while setting aside the larger equitable award, holding that damages should instead be measured by the difference between the position the funds received at closing and the position they would have held had the collateral been worth what the appraisal represented. The ruling altered the remedy. It did not disturb the finding that the investment had been induced by fraud.

The litigation continued on remand. In 2021—seven years after the verdict and more than a decade after the transaction—the team secured a $121 million fraud judgment against Credit Suisse. The result reflected a willingness to remain with the case through trial, appellate review, remand, and renewed litigation over the proper judgment.

By then, the appraisal no longer commanded authority merely because it was called an appraisal. Its assumptions, revisions, and development had been exposed to examination. The professional label could no longer substitute for the work beneath it.

Following the Professional Chain

The Lake Las Vegas litigation also illustrates a recurring feature of Tsai’s practice: the inquiry does not necessarily stop with the institution that benefited from the transaction.

The funds separately pursued fraud and negligence claims against CBRE, the firm whose letterhead the appraisal carried. That case resolved confidentially after extensive factual and expert discovery. The two actions followed different defendants through the same transaction—one examining the bank that arranged the financing, the other the professional work that gave the financing its apparent foundation.

A similar pairing arose from a $500 million collateralized-debt transaction. Tsai represented investment funds in a $100 million fraud action against Royal Bank of Scotland and, separately, in a legal-malpractice action against Orrick, Herrington & Sutcliffe concerning the law firm’s transactional work on the same deal. RBS settled before depositions. Orrick settled before summary judgment.

Together, the cases reveal a pattern. A commercial loss may have a principal actor at its center, but it often travels through a network of professional authority. The bank supplies capital and structures the deal. The law firm prepares the documents or gives the advice. The appraiser supplies a valuation. The accountant lends financial statements the credibility of an audit. When the transaction collapses, each participant may characterize its own role as narrow, technical, and dependent on information supplied by someone else.

Tsai’s cases follow the loss through that chain. In a $90 million malpractice action, she represented Otto Bock Healthcare North America against Duane Morris over antitrust advice connected to an acquisition that later drew a Federal Trade Commission challenge. The case proceeded through factual discovery and expert reports before resolving confidentially. She has also represented Rabobank International in fraud and negligence claims arising from audits performed by PwC Mexico and Oroco Capital in a pre-suit malpractice dispute concerning McDermott Will & Emery’s transactional work on the sale of an overseas maritime-security company.

These cases do not assume that professional status proves wrongdoing. They refuse to let professional status stand in for correctness.

The engagement must be reconstructed. What was the professional retained to do? What information was available? Which standard governed the work? What advice was actually given? Which assumptions were accepted without adequate scrutiny? What followed because the assignment was not performed as required?

Expertise becomes part of the evidence rather than a reason to stop asking questions.

Complexity Reduced to Proof

Commercial fraud cases are often described as complicated because their documents are complicated. But the documents serve two functions at once: they contain the proof, and they can obscure its significance.

A transaction may span hundreds of pages. Responsibility may be divided among bankers, lawyers, appraisers, officers, advisers, and committees. Each participant can describe a limited function until the outcome appears to have occurred without anyone making a consequential decision.

The plaintiffs’ lawyer must master that complexity without passing its full weight to the factfinder.

Tsai’s courtroom method is to reduce the record without reducing the truth. Whether addressing a judge or a jury, she has said that she tries to remain authentic and tell a story a person can follow: how the client was harmed, why recovery is justified, and why the case warranted years of effort. However technical the record, the ultimate questions usually return to subjects a factfinder already understands—fairness, responsibility, judgment, and consequence.

Simplicity in the courtroom comes from knowing which details carry the case and which merely enlarge the record. The lawyer must understand the assumptions that altered the transaction, the communications that reveal why they changed, the professional duties that governed the work, and the explanations that fail when set against the evidence. Only then can thousands of pages be distilled into a small number of accurate propositions.

The document may present one account. The history of its creation may reveal another. The case develops from the distance between the two.

That method carries across industries. Tsai has represented Main Street Capital in fraud and contract litigation arising from the sale of an oilfield-services company; NexBank in a $60 million fraud and contract case; Versata Software in a $50 million intellectual-property dispute with General Electric; and a liquidating trustee pursuing recoveries connected to a $960 million Ponzi scheme. The legal settings changed, but each case required the same movement from a sprawling record toward a coherent account of responsibility.

The Explanation That Takes the Property

In the Emerald Lake dispute, the stakes were more personal.

Carling O’Brien had co-founded Emerald Lake Capital Management. Her case was that her business partner terminated her for cause as part of a bad-faith effort to take her partnership interest and carried-interest rights. As in many institutional disputes, the decision arrived with an explanation constructed to make the result appear contractually justified.

Tsai and her partner Ryan Goldstein led the team through a two-week arbitration hearing in Los Angeles. After the three-member panel issued an interim decision in O’Brien’s favor, the parties resolved the dispute on confidential terms.

The case involved partnership agreements, fiduciary duties, compensation interests, termination provisions, and private-equity structures. At its center was a direct question: can one partner take another’s ownership interest by constructing the explanation that makes the taking appear lawful?

An earlier case had posed the same question on a larger canvas. Bruce Bakerman, a Harvard-educated lawyer, had served as in-house counsel to the companies behind Grey Goose vodka and held a ten percent stake in Grey Goose Bottling Company, the entity that owned the closely guarded recipe and the production operations in Cognac, France. He held no equity in Sidney Frank Importing Co., the distribution parent. When the Grey Goose brand was sold to Bacardi for $2.5 billion, the internal allocation directed $19 million of the purchase price to the bottling company. The arithmetic rendered Bakerman’s stake nearly worthless.

His case was that the taking was then sealed with an ultimatum. Presented with the terms at the last moment, he was given roughly half an hour to decide: accept $700,000, keep his job, and sign a comprehensive release—or refuse, be terminated, and receive nothing. He signed and cashed the check.

Prominent firms declined the case afterward, treating the signed release and the cashed check as an impenetrable shield. Tsai and her colleagues looked past the contractual surface to the Delaware Court of Chancery’s entire-fairness doctrine, under which a self-interested transaction must be defensible in both process and price. After rulings by Chancellor William Chandler allowed the claims to proceed despite the release, the defendants settled.

The same concern appears in the Renren derivative litigation in New York, where Tsai’s firm served as lead counsel for minority shareholders who alleged that insiders of the Chinese social-media company had transferred its most valuable investments to entities they controlled at a fraction of their worth. The defense relied in part on Cayman Islands incorporation and disputed questions of jurisdiction and standing. In 2022, the court approved a settlement of at least $300 million, paid directly to minority shareholders rather than returned to a company the insiders still controlled.

A bank describes a transaction as contractually authorized. A professional characterizes advice as reasonable. A partner presents a termination as justified. A controller calls a lopsided allocation ordinary corporate action. In each instance, the explanation does more than defend the conduct after the fact. It attempts to control how the conduct will be understood.

The lawyer must separate the event from the account later given of it—determining what happened, then testing whether the explanation can survive the record. Contractual and corporate mechanisms can allocate property, compensation, and control. The question is whether those mechanisms were exercised for the purposes the governing relationship permitted or used instead to give a private taking the appearance of ordinary corporate action.

The Plaintiffs’ Side

Tsai did not begin her career on the plaintiffs’ side.

She graduated from Princeton with highest honors in politics and earned her law degree with honors from the University of Texas, where she was elected to the Order of the Coif and served on the Texas Law Review. She clerked in the United States District Court for the Southern District of Texas, practiced at Latham & Watkins in Los Angeles, and became a partner at Diamond McCarthy—years spent inside the traditional architecture of commercial litigation.

In late 2009, she left to help build something different. With William T. Reid IV, Jason Collins, Eric Madden, and a small group of colleagues, she co-founded a firm organized around contingent- and mixed-fee trial work. Nine lawyers made the move.

The beginning was anything but institutional. The founders shared small subleased rooms in Austin, and a wooden plank laid across bankers’ boxes served as a conference table. Tsai was helping build the practice while raising an infant, without any assurance that clients would follow a newly formed plaintiffs’ boutique in Austin.

The uncertainty was inherent in the model. A contingent or mixed-fee practice ties the firm’s fortunes to its own judgment because the lawyers commit resources and share materially in the risk of the result. Case selection, factual investigation, and trial preparation become business necessities as well as litigation decisions.

The model also creates opportunities that many defense-oriented firms cannot pursue. Institutional relationships and conflict checks prevent many large firms from suing banks, corporations, accounting firms, and major law practices. Tsai works in precisely that territory, bringing sophisticated commercial claims against defendants accustomed to retaining the largest firms available.

Her response to institutional scale is not to imitate it. The team begins earlier, develops a deeper command of the record, narrows the theory to what the evidence can support, and prepares to try the case if no fair resolution is reached.

The number of confidential settlements in her record should not obscure that point. Leverage in these cases is not generated by rhetorical aggression. It comes from persuading an institutional defendant that the plaintiff has reconstructed the transaction, retained the necessary experts, anticipated the principal defenses, and is prepared to present the dispute to a factfinder.

Building the Institution

When Tsai became managing partner in 2021, her responsibilities extended beyond building individual cases. She became responsible for the institution that selects them, finances them, staffs them, and decides which risks the firm will bear.

That role carries particular weight in a plaintiff-side commercial practice. Leadership requires more than dividing work among lawyers. The firm must decide which claims justify years of investment, how to maintain quality as it grows, how to develop younger lawyers into trial advocates, and how to preserve cohesion when a single case can demand extraordinary commitments of time and capital.

Tsai has spoken publicly about talent retention, deliberate hiring, and the construction of a healthy firm culture. The subject aligns naturally with the demands of her practice. A firm that expects its lawyers to sustain prolonged litigation against larger institutions cannot treat its internal culture as incidental. The strength of the trial team depends on whether people are trained, trusted, and given reasons to remain through the life of the case.

Her leadership has also been recognized outside the firm. The State Bar of Texas Asian Pacific Interest Section gave her its Justice David Wellington Chew Award. Law360 named her a Titan of the Plaintiffs Bar in 2025, and Lawdragon—after selecting her for its 500 Leading Lawyers in America more than ten times—designated her a Legend. Benchmark Litigation has repeatedly included her among the nation’s Top 250 Women in Litigation.

Her institution-building extends beyond the firm. She has chaired the State Bar of Texas Asian Pacific Interest Section, served as president of the Austin Asian American Bar Association, chaired the Austin Bar Association’s Bench Bar Committee, and served as vice chair of Austin’s Ethics Review Commission. She has also served as board secretary of the Texas Fair Defense Project, as a trustee of the University of Texas Law School Foundation, and on the board of the Texas Law Review Association. She mentors first-year law students and, with Reid, teaches a course in complex financial litigation at Texas Law built on case studies from the firm’s docket.

Those positions place Tsai inside institutions that shape access to the profession, relations between lawyers and courts, ethical government, indigent defense, legal education, and the development of younger attorneys.

Truth Made Legible

Tsai originally planned to become a broadcast journalist.

The distance between journalism and trial work proved shorter than it first appeared. She has described the underlying impulse of both professions as finding out the truth and telling people about it. Each begins after someone else has already organized the facts. Documents have been written and decisions explained; institutions have selected the language through which their conduct is meant to be understood.

The investigative habit appeared before she entered practice. At Princeton, her senior thesis won the politics department’s Lyman H. Atwater Prize, and a portion of it was later published in the Asian American Policy Review. At Texas, she published a student note in the Texas Law Review. The discipline is consistent with the practice she later built: assemble a record, test the prevailing account, and determine what the evidence can sustain.

In litigation, the work is not simply to collect more information. It is to determine which account the record can support.

That requires moving backward through layers of financial and professional authority until the underlying decisions become visible. An appraisal changes because someone changes its assumptions. Advice exists because someone selected the information and reasoning on which it rests. An ownership interest is lost because identifiable people invoke contractual powers for particular purposes.

The inquiry also moves outward. Who supplied the professional work that allowed the transaction to proceed? Which institution benefited? Which adviser gave the deal its credibility? Who possessed the authority to stop it? Where did the explanation originate, and what does the chronology show about when it was constructed?

Much of the proof lies buried in complexity, but the case cannot end there. It must return to a clear account of what occurred, who made the decisive choices, what they knew, and who bore the loss.

That is the defining movement of Lisa S. Tsai’s practice: from document to decision, from institutional explanation to evidence, and from a record that disperses responsibility to a narrative that makes responsibility legible. Beneath every authoritative surface there is, somewhere, a weekend when a number changed—and the people who changed it.
