Example #1

Let us consider a scenario where Gordon, a Certified Public Accountant (CPA), has been newly assigned as the professional responsible for verifying documents and conducting a comprehensive review of the operations of Company X. This assignment comes as Company X prepares for its upcoming initial public offering (IPO) scheduled for the following month.

The primary purpose of the assurance was to ensure the company and, most importantly, the prospective investors that the company’s papers were clean. Gordon was supposed to conduct the examination and submit his report within a week.

Example #2

PricewaterhouseCoopers (PwC) has secured a significant audit and assurance contract with HSBC on the London Stock Exchange. The contract, set to span a decade from 2024 to 2034, is valued at approximately $1.3 billion. PwC emerged as the preferred choice following a competitive tendering that pitted them against Deloitte. 

This milestone underscores PwC’s continued commitment to providing audit and assurance services at the highest level, particularly in the challenging landscape of one of the most complex and sizeable audits within the London Stock Exchange. It is worth noting that PwC’s reappointment is contingent on annual HSBC shareholder approval, reflecting transparency and accountability in this critical financial function.
