OUM is a Public Company Accounting Oversight Board (PCAOB) registered firm with extensive Securities and Exchange Commission (SEC) experience.

Public companies face the highest level of scrutiny, as the need for financial transparency and responsibility are stressed more and more in financial statements. Consequently, the rules and regulations, procedures and deadlines that these companies face can be daunting. Because you confront countless challenges, the need for an experienced accounting firm with the ability to keep up with your operations is absolutely crucial.

Publicly held companies find that the sheer volume of SEC and PCAOB rules and the SEC's numerous unpublished administrative positions prompt many complex issues and questions. OUM has committed substantial resources to handle a wide range of SEC issues characteristic of today's complex regulatory environment.

OUM is not a newcomer to the demands of SEC clients. Our SEC group consists of professionals with many years of experience working with public companies, including those who have become public through "reverse mergers." As one of the largest SEC practices in the bay area, we have worked with public companies in industries ranging from technology to life sciences to consumer products to insurance to manufacturing. We currently audit public companies with market capitalizations that range from the millions to the billions.

As independent auditors, OUM has assisted its clients with over thirty-five capital market financing transactions totaling more than $1.4 billion since 2005 alone.

For companies with an eye towards going public, we have the experience to walk you through this involved transition. We can work seamlessly with your team of attorneys, investment bankers, and underwriters to navigate the complex issues inherent to the IPO process. Work with OUM and you will find our approach to be efficient, responsive, and proactive.

Our integrated audits for public companies combine the financial statement audit with an audit of the company's internal control over financial reporting. Our approach to these integrated audits reflects the top-down, risk-based methodology advocated by regulators as a way to make audits more efficient without losing the benefits of Section 404 of the Sarbanes-Oxley Act of 2002.

You can always expect us to:

  • Perform audits in accordance with PCAOB standards
  • Help you to greatly reduce the risk of financial miscommunication
  • Ensure relevant information is provided to decision makers in a timely manner
  • Keep you updated on current developments in financial reporting
  • Provide you with all required PCAOB communications and other observations for audits and quarterly reviews
