In today’s business landscape, the accounting rules are shifting constantly. New standards, including convergence with international principles and other regulatory changes, are impacting businesses radically and at a faster pace than ever before. As a result, managing business risks has never been more important.

We offer Financial Audit and Attest services in San Diego and San Francisco, which are designed to not only satisfy your regulatory requirements, but also to help you identify and reduce those business risks. In addition, a high-quality audit can increase your company’s access to capital and increase shareholder value.

From start-ups to large, multinational businesses in both the public and private sectors, OUM’s CPA professionals have the right experience to tailor our audit and attest services to the unique situations of each client.

In addition to providing our clients an independent and objective view of their financial information, we offer valuable insight and advice on corporate governance and business practices, with the overall objective of increasing shareholder value and decreasing business risks. This is possible because we are consultants first. Our partner-to-staff ratio of 1:5 (where the industry average is 1:7) ensures our clients always have access to experienced professionals.

Our audit and attest clients also benefit from our deep industry expertise. OUM advises clients on risks and opportunities that are unique to their industries. Audit and attest services are not simply a commodity or compliance exercise. Our approach includes involving firm specialists in accounting, tax, valuation, and information technology, which often can result in efficiencies and process improvement opportunities for our clients’ businesses. By focusing on high-quality procedures and incorporating firm specialists in our process, we provide assurance to stakeholders through the quality and transparency of our clients’ financial reporting.

Financial Statement Audits & Public Company Audits

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 initial public offerings and “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 of dollars.

As independent auditors, OUM has assisted its clients with well over 100 securities offerings totaling more than $3.0 billion since 2005.

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 public 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.

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

Employee Benefit Plan Audits

A well performed audit is vital protection for your employee benefit plan. Generally, federal law requires employee benefit plans with 100 or more eligible participants as of the beginning of the plan year to have an audit filed with its annual Form 5500. If your employee benefit plan is required to have an audit, one of the most important duties of the plan administrator is to hire a qualified independent public accountant.

OUM has an extensive background in employee benefit plan audits. We have found that companies who engage us enjoy a reduction in audit fees and an increase in client service. We make significant investments in our relationships with employee benefit plan clients.

Reviews and Compilations

Our financial statement review process is less extensive than an audit. It relies primarily on inquiry, analytics, an understanding of the organization and contractual arrangements in order to provide limited assurance that your financial statements are presented in accordance with generally accepted accounting principles.

Our process of applying analytics to the company’s current and historical data against industry information, combined with our ability to ask the right questions, results in valuable information for our clients. In addition, we help our clients adapt these techniques so they can better evaluate their operations on a month-by-month and even week-by-week basis.

Compilations provide the lowest level of assurance. Our service is based on obtaining a general knowledge of the organization and presenting your financial information in the form of financial statements.

Agreed Upon Procedures

From fact-finding to gaining important insights on specific components of a business, situations often call for a more precise approach to data analysis. In these circumstances an “Agreed-Upon Procedures” engagement can be a useful solution. Under such an arrangement we carry out very specific work to cover your areas of concern in a laser-focused manner. This avoids carrying out unnecessary work to provide a much broader opinion and makes the scope of work for you entirely clear.

OUM’s “Agreed-Upon Procedures” professionals are highly skilled in examining financial records and operational efficiencies for specific purposes – issuing clear, precise, and high-quality results. Upholding the highest level of service and an impartial perspective, we provide service in the areas of due diligence, document inspections, compliance, performance, internal controls, projections and forecasts, and mathematical computations and calculation verifications, to obtain and verify various financial and operational data for our clients’ specified needs. Conducted in accordance with the standards established by the American Institute of Certified Public Accountants (AICPA), our “Agreed-Upon Procedures” services deliver the tailored solutions and objective expertise you require, without the commitment of a more in-depth engagement.
