Lessons from the PFI Ponzi scheme

When California businessman Kenneth Casey died in 2020, he left behind a Ponzi scheme that defrauded more than 1,200 investors. Those investors sued Casey’s lender, Umpqua Bank, accusing it of being a partner in the scheme. In March 2025, Umpqua agreed to pay $55 million to those investors. Here, the author details the scheme, the litigation that followed and how banks can strengthen their due diligence procedures to avoid accusations of fraud.

In Novato, California, just north of San Francisco, investment manager Kenneth Casey was a well-connected and renowned philanthropist. He sponsored and donated to the World’s Children organization and co-founded the NextGen Marin housing, business and community think tank. As the primary benefactor for Burt’s Children Center, Casey dressed up as Santa Claus, distributed gifts and performed Christmas shows. He was also a member of the Marin County Human Rights Commission.  

When Casey died of a heart attack in May 2020, NextGen Marin released a statement praising the local philanthropist. “Mr. Casey’s dedication to serving his community continues to be an inspiration for NextGen Marin.” Novato Mayor Denise Athas commented that Casey was a “true adventurer.… very free with his generosity to others.” 

But a different perspective of Casey emerged after his death. Casey’s wife, Charlene Albanese, the beneficiary of his estate, initiated an independent audit of Casey’s investment companies, Professional Financial Investors and Professional Investors Security Fund (both collectively referred to as “PFI” in this article). According to Albanese’s attorneys, the audit revealed “legitimate questions involving the structure and investment history of Mr. Casey’s companies.” They asked the U.S. Securities and Exchange Commission (SEC) to investigate. According to the SEC’s investigation, Casey directed PFI’s employees to falsify financial statements to convince investors that their investments were safe and profitable. More than a year after his death, in June 2021, the securities regulator charged Casey’s estate with defrauding investors in a Ponzi scheme.   

PFI purchased multi-unit housing and commercial office buildings mainly in Marin County, California. To finance those properties, PFI borrowed money from Portland, Oregon-based Umpqua Bank, and relied on funding from investors, who were promised and paid an established rate of return between 7% and 9%. Beginning in the 1980s, rents from the properties were used to pay the mortgages on bank loans and investor-return proceeds. As real estate prices and rents rose, PFI’s properties became increasingly attractive investments. Investors initially reaped the benefits with high yield returns. But as the story goes with Ponzi schemes, the operation unraveled, and investors stopped receiving returns. 

In August 2020, just a few months after Casey’s death, PFI’s investors sued Umpqua Bank for allegedly “aiding and abetting” the scheme and ignoring Casey’s criminal past. Casey’s reputation as a community leader obscured reality: In 2017, Casey had been stripped of his Certified Public Accountant (CPA) license after being convicted of bank fraud and tax evasion, and being sentenced to 18 months in prison. As one former investor told North Bay Business Journal in a 2022 article, Umpqua Bank should’ve known about Casey’s past. The investors’ suit against Umpqua wasn’t resolved until earlier this year in March when the bank agreed to a $55 million payout. [For a full timeline of the events, see “Milestones in the PFI Ponzi scheme investigation” at the end of this article.] 

PFI’s scheme and subsequent class-action lawsuit against Umpqua Bank highlight the very real risks that financial institutions face when they don’t thoroughly vet customers — even ones who appear to be upstanding citizens. This article details the elements of the PFI Ponzi scheme, the suit against Umpqua and its possible role in the scheme, and what banks should do to strengthen their due diligence procedures to fortify themselves against accusations of fraud. 

A long-running scheme

While Casey is considered the mastermind of PFI’s Ponzi operation, he did have a partner in crime. Lewis Wallach, onetime PFI bookkeeper, was promoted to chief executive officer (CEO) following Casey’s fraud conviction and CPA license revocation. In September 2020, the U.S. Department of Justice (DOJ) charged Wallach with running PFI as a “classic Ponzi scheme.”

Casey and Wallach greatly expanded PFI’s operations once Casey was released from prison. They’d soon become one of the largest owners of commercial properties in Marin County. Bankruptcy documents indicate that the scheme started in 2007. In 2020, during the COVID-19 pandemic, both Casey and Wallach assured investors that PFI was financially secure due to large cash reserves, a reliable line of credit from Umpqua, and the ability to sell PFI-owned properties. However, PFI wasn’t flush with reserves, and commercial real estate property values didn’t have enough equity to produce cash when needed. PFI filed for bankruptcy in July 2020, just two months after Casey’s death; more than 1,200 investors lost an estimated $149 million, according to case records. 

Shortly after the discovery of the Ponzi scheme, a forensic accountant estimated that PFI owned interest in about 70 real estate properties that once had an estimated value of more than $550 million. Those properties had bank debt exceeding $400 million, and PFI owed more than $250 million to investors. The bankruptcy’s selloff of properties yielded only $436.5 million, due to both a general decline in the commercial real estate market and PFI’s decision to intentionally delay building maintenance, which saved money but also decreased the property values due to the buildings’ and grounds’ poor conditions. PFI’s financial stress was also exacerbated by funds transferred to Wallach’s and Casey’s personal accounts. Overall, $26 million in investor money went to Wallach and Casey, which they used to purchase a mansion in Malibu, luxury vehicles and jewelry, among other items.

Casey and Wallach lured investors with the promise of high returns paid on a scheduled term or rolled back into the investors’ accounts. These investments appeared sound, since the yield payments were initially consistent. Another attraction for investors was Casey’s image as a community leader who created impressive financial portfolio presentations and paid consistent yields to investors for years without incident. Each investment was also tied to a parcel title number on investors’ account statements, which indicated the specific property purchased with investors’ money and created an impression of precise accounting.  

PFI’s operation was an illusion of financial integrity. Secretly, Casey revised PFI’s general ledger to fraudulently reflect an increase in cash reserves and a decrease in expenses on the financial statements. He funneled investors’ money into paying off bank loans, funding yields for earlier investments, and lining his and Wallach’s pockets.  

PFI’s investors

For a Ponzi scheme to work, it needs willing investors. PFI found them in teachers, doctors, attorneys, accountants and retirees. Investors saw many upsides to entrusting their money with PFI. It was run by a well-known and upstanding business and community leader with a seemingly good history of paying high yields in an area with increasing real estate values. As long as people didn’t dig too deeply into Casey’s background, investing in PFI seemed like a sound choice.

Casey’s marketing strategy added to PFI’s appeal. When prospective investors inquired about PFI’s investment structure or requested audit reports, Casey told them to seek other investments. Potential investors were hard-pressed to find an opportunity with returns as consistently high as PFI’s.  

PFI also didn’t accept every prospective investor. Casey limited investment opportunities, creating the illusion of scarcity and reducing inquiries about the business plan. Had Casey been more transparent and made the opportunity available to more parties, savvy investors would have noted two primary risks for investing in PFI properties: (1) Casey’s prior fraud conviction, and (2) a lack of independent audit or SEC review. [See “Investment tips to reduce your risk of fraud” at the end of this article.]

One of those savvy individuals included an investment adviser whose tax adviser friend’s client was considering investing in PFI. The investment adviser wrote about his experience cautioning the friend’s client. He knew about Casey’s criminal history and gave his friend questions to ask him. According to the adviser, Casey told the client that he wouldn’t answer questions and that he had many others interested in investing. The adviser remarked that Casey’s response was a red flag, but the friend’s client decided to invest — they’d also lose money in the scheme. 

PFI’s victims weren’t sophisticated investors and had little reason to suspect that their investments weren’t sound, especially as they received regular statements and proceeds for years. For many investors, PFI was their only asset; many used their yields for living expenses. One PFI investor was so happy with his initial $250,000 investment that he mortgaged his house for an additional $400,000 investment. Other investors were retirees who used PFI yields to supplement their incomes.  

Settlement calculations

PFI’s bankruptcy proceedings required that losses would be accounted for and that PFI’s remaining assets would be distributed fairly among investors. The sale of PFI’s properties couldn’t cover the money lost, and a complex accounting plan divided up the remaining assets.  

After the loans were paid off and all legal fees and losses on the property sales were accounted for, the remaining assets were split among investors based on several factors, including total investment amount and yields received over the duration of the investment. Even investors who’d since cashed out their investments were incorporated into the settlement process through a court order to pay back all or a portion of the funds. Other investors who’d received yields higher than initial investments were on the hook to pay but lacked the resources to do so. 

The bank’s role

As the bankruptcy costs accumulated, investors’ attorneys focused on Umpqua Bank. According to U.S. and California state laws and regulations, while banks are responsible for lending money in exchange for their customers’ principal and interest payments, they typically aren’t responsible for their customers’ poor business decisions or failures. A bank’s fiduciary duty generally doesn’t extend beyond providing loans, unless a special relationship exists, such as involvement in the borrower’s business. However, identification of such a relationship isn’t always obvious and typically requires, among other considerations, the extent and level of the bank’s involvement.    

San Francisco-based Circle Bank was PFI’s first lender until Umpqua Bank purchased it in 2012. Umpqua maintained Circle’s relationship with PFI and hired some of its staff during the acquisition. One of those former Circle employees was June Weaver, who’d go on to manage Umpqua’s relationship with PFI. According to the lawsuit against Umpqua Bank, Weaver, whose title was “private banker,” assisted in PFI’s banking transactions, including transfers to avoid overdrafts. Plaintiffs contended that transferring funds between various PFI bank accounts to prevent overdrafts constituted a special relationship. This doesn’t mean that Umpqua was purposely facilitating a Ponzi scheme, but it was relevant when combined with other factors, such as Umpqua’s anomaly detection algorithm flagging PFI 146 times between 2018 and 2020. According to the investors’ lawsuit, “On 179 occasions, Weaver or others at the branch personally transferred a total of $5.2 million to one of Casey’s or Wallach’s personal accounts.” The complaint quotes an Umpqua Bank branch manager who exclaimed in an email, “Holy moly I see transfers were allowed ($40,000.00 transfer from the PFI [transfer account] to [Casey’s personal account] on May 12 and $21,000.00 on April 12 and $25,000.00 on March 31).” 

Moreover, Umpqua Bank managers reportedly knew about Casey’s fraudulent past. According to the plaintiff’s document seeking class-action status, “The branch even helped Casey hide his involvement by taking his name off bank records, so [PFI] could obtain real estate loans from other institutions.”

Attorneys for PFI’s investors argued that Umpqua had a fiduciary duty to monitor its customers for unethical behavior. Umpqua asked a judge to dismiss the case, but the request was denied. In the bank’s filing, Umpqua argued, “The complaint by plaintiff investors seeks to hold Umpqua liable for their failed investment. But their complaint fails because they do not — and cannot — allege facts showing that Umpqua knew about the scheme or substantially assisted with Casey’s scheme as required to maintain their two claims for aiding and abetting fraud and breach of fiduciary duty.” In denying Umpqua’s request, the U.S. District Court judge stated that “Umpqua is required by law to conduct extensive customer due diligence, especially for high-risk and high-net-worth customers like Casey.” According to the judge, the bank had an obligation to “know” its customer and monitor “red flags” indicative of fraud. 

Bank litigation involving Ponzi schemes

Umpqua’s relationship with PFI might’ve been dismissed as an isolated event and an unfortunate set of circumstances from acquiring Circle Bank — if not for two other lawsuits Umpqua faced involving fraud. One of the cases involved a Ponzi scheme perpetrated between 2008 and 2012 by Berjac, an insurance-premium financing company based in Oregon. According to the U.S. Attorney’s Office for the District of Oregon, “[Berjac] solicited investments purportedly used to finance loans to small businesses to pay for those businesses’ insurance premiums. Investors were promised between five and seven percent returns.” The scheme involved 400 investors, many of whom lost their life savings.

In the other case, Oregon-based Summit Accommodators assisted its customers in lawful federal income tax deferral transactions. Typically, a customer sold income-producing property, allowing Summit to hold the proceeds of the sale. Evidence presented during the trial showed that Summit began using its clients’ exchange funds for personal investments. In the two Oregon cases, Umpqua agreed to settlements of $11 million and $13 million, respectively.

Umpqua Bank doesn’t stand alone in its culpability for a customer’s fraud scheme. In February 2023, TD Bank reached a $1.2 billion settlement with the victims of a Ponzi scheme orchestrated by Allen Stanford, former chair of Stanford International Bank’s (SIB) board of directors. Stanford was convicted of investment fraud for misappropriating $7 billion from SIB to finance his personal businesses. In a separate case in September 2024, the Bank of Montreal (BMO) and its subsidiary, Harris Bank, had a $564 million judgment against one of its subsidiaries involving Thomas Petters, who was sentenced to 50 years in prison for perpetrating a $3.7 billion Ponzi scheme. Petters obtained billions of dollars by inducing investors to provide Petters Company, Inc. funds to purchase merchandise that would be resold to retailers at a profit. But no such purchases were ever made. A court subsequently overturned the judgment against BMO. Additionally, in June 2024, Wells Fargo faced a proposed class-action lawsuit alleging that the lender aided and abetted a $300 million Ponzi scheme that drained more than 1,000 investors, mostly seniors, of their life savings.

Whether these class-action lawsuits against banks have a legitimate claim to restitution for money lost due to alleged “aiding and abetting” and “breach of fiduciary duty,” bank risk management should ask the following questions to avoid these thorny litigation issues:

• What level of involvement does the bank have in its borrower’s operation?
• At what point should the bank’s duty to “know its customer” be scrutinized when examining potential fraud?
• Are banks underutilizing, ignoring or misinterpreting results from tools such as artificial intelligence (AI) that suggest potential fraud?

Generally, banks generate revenue regardless of whether borrowers act responsibly or irresponsibly to their respective shareholders, investors or other creditors. Banks have a duty to their own shareholders to keep lending relationships intact to maintain profitability and sound investments. But managing borrower relationships requires robust risk management and audit functions to maintain regulatory compliance, prevent defaults and help avoid litigation, such as complaints brought about by victims of Ponzi schemes. Risk management and controls aren’t free, but they’re a necessary part of bank operations and should fit the level of complexity, cost and effort required to mitigate potential losses. 

Seeking restitution for victims

During the PFI trial, investors asserted that Umpqua Bank knew about Casey’s criminal record and its 146 fraud alerts. They also pointed to the bank’s regular assistance in transferring money to Casey’s personal accounts and PFI’s status as one of the largest customers for Umpqua’s Novato branch. According to the lawsuit, “Umpqua assigns branch employees a goal for customer accounts and total deposits and ties bonuses, commissions, and incentives to those metrics.” The lawsuit also stated that “Reporting PFI’s fraudulent activity would have caused the Novato branch to lose dozens of accounts and over 10% of its total deposits, leading to reduced compensation, worse performance reviews, and potentially even loss of employment.” Goals and metrics are common employee incentives in the banking industry; but without adequate controls, these incentives may increase risk.

Following the mistrial, a settlement conference was held at the U.S. District Court for the Northern District of California, and the parties, which included Umpqua bank attorneys and attorneys representing PFI investors, agreed that Umpqua would pay $55 million to settle all class claims, a tentative agreement subject to review and final court approval. The maximum damages the class action could’ve recovered at trial (before prejudgment interest) was $149 million.

Avoiding future Ponzi schemes

As the investors’ class-action lawsuit asserted, Umpqua Bank failed to thoroughly vet Casey early on and to establish sound procedures to identify and manage fraud. Stronger due diligence and proper mitigation techniques might’ve decreased its exposure to fraud, including the following practices:

• Review details on major customer accounts listed under the acquired bank, during mergers and acquisitions. Criteria for maintaining a banking relationship with a major borrower may vary between banks. There may also be different criteria within the same bank when regulations and policies aren’t applied consistently to customers who contribute highly to the bank’s bottom line. Reviewing customer accounts and their practices, including audit reports and the background of key personnel prior to acquisition, may help identify potential fraud issues.
• Develop and integrate meaningful and actionable fraud detection and response management. AI models can help identify fraud when users target them with precision and deploy them to actively manage and mitigate alerts. However, models can be overconfident about wrong answers or underconfident about correct ones, making it tough for users to know when a model can be trusted. Models that aren’t specifically targeted and produce little feedback may cause fraud to go undetected. Conversely, overly cautious models that trigger too many notifications may produce false positive alerts that are ignored because of their frequency or lack of criteria for management and mitigation. Ultimately, a bank’s risk management strategy should include meaningful and actionable criteria for AI tools. Umpqua’s 146 fraud alerts concerning PFI should’ve led to actions against PFI or an adjustment to the alert criteria for more accurate results.
• Enforce restrictions on the types of assistance bank employees are allowed to perform for their customers. This may include transfers between accounts that avoid overdrafts and potentially mask or delay the discovery of more serious cash management issues. Transactions such as transfers to the personal accounts of commercial customers’ managers should be handled with greater scrutiny, including communication with bank personnel with risk and audit expertise. The restrictions may also embody regulatory requirements covering anti-money laundering rules.

Opportunities to protect the financial landscape

Ever since Charles Ponzi first conceived of a gambit to buy and resell International Reply Coupons with startup funds from investors and dangled the promise of a 50% profit in 45 days more than 100 years ago, the pyramid scheme bearing his name continues to threaten the financial landscape. But risk managers, auditors and other anti-fraud professionals have better tools and knowledge now to fight these persistent schemes. By strengthening due diligence and mitigation techniques, banks can effectively identify and curtail the impact of future Ponzi schemes. It’s not enough to claim ignorance of customers’ schemes to avoid litigation. Banks must know their customers and work to protect their accounts through sound risk management and fraud detection responses.

Investment tips to reduce your risk of fraud

Many of PFI’s investors were novice investors who didn’t probe deeply into PFI’s business plan or Casey’s background beyond his stalwart community-member image. But the key to making a good, fraud-resistant investment is asking critical questions and doing the requisite research to ensure that the investment is safe and the individuals involved are trustworthy. Here are some tips and questions to consider if you’re contemplating a business investment.

• Ask questions. When deciding to invest, it’s important to factor in the marketer’s willingness to provide key details. It’s most likely a red flag if the marketer refuses to answer questions, such as when Kenneth Casey avoided answering investors’ inquiries about his business plan. Deciding whether to invest shouldn’t be influenced by other investors’ willingness to proceed without the details. Also, don’t be convinced to invest because of a bank’s involvement; these institutions secure their loans with assets — a safeguard that might not be available to individual investors.
• Is the investment registered with the SEC? Many investments aren’t registered with the SEC. That means greater due diligence is required to vet the opportunity, such as evaluating your risk appetite and researching investment managers and their histories.
• Are there any independent audits performed? If the response to a question on audit reports is to immediately dismiss it, it may be best to walk away, even if the opportunity has a history of operating without incident. Even though they believed Casey had a solid history of providing returns, his refusal to provide audit reports should’ve made investors cautious about moving forward.
