Overview

Chicago Options Associates (COA) is a finance company incorporated in Chicago, Illinois, whose stated business specialization is the trading of options and futures contracts. The company was established in 1987 by Michael E. Davis and Oliver R. W. Pergams, both of whom had University of Chicago backgrounds. Its early operations included offices in Chicago and Philadelphia, reflecting a business focused on financial markets rather than a consumer-facing brand. The company became publicly notable partly through its association with Jimmy Wales, who later co-founded Wikipedia. In 1994, Michael Davis was serving as COA's chief executive and hired Wales, then a graduate student in economics, to analyze the firm's pricing-model strategy. Wales left his graduate program and worked for COA as research director from 1994 through 1998. His work involved analyzing financial markets, including movements in foreign currencies and interest rates, and Davis encouraged him to take a more aggressive approach to trading. Davis, Wales, and Tim Shell later collaborated on the Internet company Bomis, and Davis and Shell subsequently became involved with Wales in the initial board of the Wikimedia Foundation. COA's business identity is therefore tied to two different aspects: derivatives trading in Chicago's financial sector and its historical connection to the early professional career of Jimmy Wales. The available reference material does not establish the company's current ownership, leadership, website, financial performance, or operating status. A 2013 reference placed the company on LaSalle Street in Chicago, but no current location is confirmed here. The company and Michael E. Davis were also defendants in litigation that ultimately reached the Illinois Supreme Court. In the underlying dispute, Brian Dowling obtained a judgment of $817,830.45 against COA and Davis. After the judgment, Davis transferred funds connected with an attorney retainer to DLA Piper, a law firm that had assisted him with the purchase of a Florida home. Dowling argued that the retainer should be available to satisfy the judgment. Lower courts ruled in Dowling's favor, but the Illinois Supreme Court reversed those decisions and ruled for DLA Piper. The case, Dowling v. Chicago Options Associates, became significant in Illinois legal practice because the court recognized the advance-payment retainer and distinguished it from other forms of attorney retainers. The court's treatment was later reflected in Illinois Rule of Professional Conduct 1.15(c), effective in 2010.

History

Chicago Options Associates was founded in 1987 in Chicago by Michael E. Davis and Oliver R. W. Pergams. Both founders had ties to the University of Chicago, and the company developed as a financial-market business specializing in options and futures contracts. Its early footprint included Chicago and Philadelphia offices. The available historical account describes the firm as having established a successful reputation in Chicago by the mid-1990s. Michael Davis was the company's chief executive officer in 1994. That year he recruited Jimmy Wales, then a graduate student in economics, to examine COA's pricing-model strategy. Wales left his graduate studies and joined the company as research director. From 1994 to 1998, he analyzed market behavior, including foreign-currency and interest-rate movements. Davis reportedly mentored Wales in more aggressive financial trading. This period later became notable because Wales went on to co-found Wikipedia and became a central figure in the Wikimedia movement. Davis, Wales, and Tim Shell formed the Internet company Bomis in 1996. When Wales moved toward establishing a nonprofit organization to manage Wikipedia in 2003, Davis, Shell, and Wales formed the initial three-member Wikimedia Foundation Board of Trustees. These relationships gave COA a place in the early professional history of one of the Internet's best-known nonprofit projects, although COA itself remained a derivatives-trading company rather than an Internet brand. The most consequential legal episode associated with the company was Dowling v. Chicago Options Associates, Inc. The underlying litigation involved creditor Brian Dowling's claim against Chicago Options Associates and Michael Davis. Dowling obtained a judgment of $817,830.45. Following entry of the judgment, Davis placed funds connected with a $100,000 retainer into a trust arrangement controlled by DLA Piper. The law firm had assisted Davis with the purchase of a home in Florida. Dowling argued that the retainer should be recovered for satisfaction of the judgment. The circuit court ruled for Dowling, and the appellate court affirmed. The Illinois Supreme Court subsequently reversed those decisions and ruled in favor of DLA Piper, holding that the advance-payment retainer became the law firm's property when paid under the relevant arrangement. The Illinois State Bar Association and Chicago Bar Association submitted amicus briefs supporting the law firm's position. The decision was important beyond the parties because it was the first Illinois Supreme Court recognition of the advance-payment retainer as a distinct arrangement. The court distinguished it from a classic retainer, which compensates an attorney for availability or a defined period, and a security retainer, which remains segregated as client-related funds. The legal principles from the decision were later incorporated into Illinois Rule of Professional Conduct 1.15(c), adopted in 2009 and effective January 1, 2010. The case consequently became a reference point for Illinois lawyers and legal commentators discussing the classification and treatment of retainers. A reference cited the company as being located on LaSalle Street in Chicago in 2013. No reliable current information in the supplied materials confirms whether COA remains active, who owns it, who manages it, or whether it maintains a public website. Its documented historical identity is that of a privately held Chicago financial company with expertise in options and futures trading and a notable connection to Jimmy Wales and the early Wikimedia Foundation.
