The legal structure of a limited liability company (LLP) differs considerably from that of a company. Moreover, an international law firm is actually an association of individually managed member firms in their respective jurisdictions. The senior partners of the member firms sit on a global board of directors of partners. There is also a „holding company“ called PricewaterhouseCoopers International Limited, a UK-based company that offers coordination. Coopers & Lybrand and Price Waterhouse gradually focused on consulting in the 1990s. The audit proved risky and costly, as the Big Six were held responsible for the bankruptcy of the companies that audited them and prompted them to pay huge settlements. In 1992, Coopers & Lybrand filed a lawsuit against them by investors in MiniScribe, a bankrupt hard drive manufacturer. Fighting claims that they should have exposed the company`s fraud, Coopers & Lybrand eventually agreed to pay investors $92 million. In another fraud case, the company made large payments in 1996 to settle claims against bankrupt companies in the media empire of the late Robert Maxwell. The accounting firm was fined by regulators in 1999 for failing to uncover Maxwell`s fraudulent transfer of $650 million from a corporate pension fund to itself. Among other things, Coopers & Lybrand`s costly settlement was related to the audit of Phar Mor pharmacies that went bankrupt in the mid-1990s. The year 1957 marked the establishment of the European Common Market.
Soon after, a merger led to Coopers & Lybrand International, which initially consisted of the company`s Canadian and Uk subsidiaries. While all of the company`s foreign subsidiaries bore the Coopers & Lybrand name in the United States, the company retained its original Lybrand name, Ross Bros. & Montgomery, until 1973. This year, the company`s management decided to introduce a single name for the entire global network of branches located on the five continents at the time. Although companies remained self-sufficient in more than 120 countries, they shared common goals and policies. In 2013, Cattles plc brought a lawsuit against PwC in the UK over the 2006 and 2007 audits, claiming that PwC had failed to conduct adequate investigations.  Cattles, a British consumer credit company, later discovered control weaknesses that led to a significant overvaluation of its credit portfolio on its balance sheet; After being listed as a FTSE250 company, it subsequently lost its listing. The filings also claimed that PwC`s Brazilian subsidiary, PricewaterhouseCoopers Auditores Independentes, played an important role in confirming Petrobras` financial reports and ignoring the warnings.  Lybrand, Ross Bros. & Montgomery emerged from the war as one of the largest accounting firms in the United States.
However, times have changed and no accounting firm could afford to limit itself to traditional auditing and accounting services. In 1952, the company entered a new arena by introducing management consulting for its clients in the banking world and large companies. This was the first of what would become a wide range of consulting services as well as information services and special software packages with the advent of PCs. While these services have in no way supplanted traditional auditing and accounting, they have had a significant impact on the business. In 1974, the company was the first to establish a career path in accounting for those with computer skills. The Great Depression was both a blessing and a curse for the accounting firm Lybrand, Ross Bros. & Montgomery. The growing company, which employed hundreds of people, faced increasingly limited business opportunities as financial institutions and businesses collapsed and went bankrupt. On the other hand, the crash across the country, and especially at the Capitol, was attributed to the lack of an independent audit of the stock exchange.
With a new chairman installed in 1933, Congress created the Securities and Exchange Commission, the regulator of public companies, and the stock exchange, resulting in a plethora of audit activities for the company. The company also participated in New Deal projects, such as acting as an independent auditor for the Tennessee Valley Authority after 1944. During the depression years, the company continued to expand, with offices opening in Illinois, Texas and Kentucky. In 1935, Robert Montgomery became president of the prestigious American Institute of Accountants. In 2010, Joe Nocera wrote in the New York Times: „In 2007, with the prospect of parole on the horizon, the same prosecutors – with what appears to be the complicity of PricewaterhouseCoopers, Yukos` longtime accounting firm – re-indicted the two men (Mikhail B. Khodorkovsky and Plato Lebedev) and introduced a new round of Kafkaesque charges.“  When senior partner John C. Scobie, a Scotsman known for being scrupulously honest, became chief of staff, he implemented new audit procedures designed to give auditors better access to a client`s activities. Scobie`s plan was to improve the auditor`s ability to assess whether accounting data reflects the actual performance of a particular company. This, in turn, would allow auditors to advise clients on the many operational factors that affect financial results. In 2018, Luke Sayers, CEO of PwC Australia, was linked to perceived conflicts of interest related to a personal investment in Australian Visa Processing (AVP), a company partly owned by PwC that submitted an offer to overhaul and operate Australia`s visa processing system that could be worth billions of dollars. which would result in a significant financial benefit for its investors.
 This investment resulted in a „storm within the company“, PwC Global`s Interjection and a review of PwC Australia`s personal investment policy for partners.  The investment opportunity was not offered to all partners or even to the entire company.  A review of how partners make personal investments was announced.   Price Waterhouse had its own legal problems in the 1990s. . .
