Audit Firm Selection: Why it Really Matters6 minute read

by

For the largest public companies in the country, selecting a new audit firm often comes down to choosing one of four firms: Deloitte, EY, KPMG, or PwC.

If all you did was read The Wall Street Journal or watch CNBC, you’d think these are the only audit firms in the country.

But that is not the case at all.

Almost 80 percent of U.S. public companies have market capitalizations below $500 million, and very few of them are audited by any of the so-called “Big Four” firms.  Instead, small-caps have hundreds of audit firms from which to choose, and too often those choices are made in a vacuum.

This article addresses a few issues that are rarely discussed in the small-cap ecosystem:

  • Why do companies have so many audit firm choices;
  • How can they weigh their options more efficiently; and
  • Are there real penalties for making a poor choice?

The audit firm selection process can be a daunting one for small-caps.  One way to simplify it is to think like an institutional investor.

Generally speaking, the smaller the public company, the higher the percentage of shares owned by retail investors (i.e., non-professional investors) versus institutional investors. For example, companies with market capitalizations below $250 million often have 70-90 percent of their public float owned by retail investors, whereas multi-billion-dollar public companies are often 85 percent-plus owned by institutional investors.

Retail investors typically don’t spend a lot of time factoring a small-cap’s audit firm into their investment decisions, but institutional investors do.

Institutional investors invest predominantly in financial performance, and the reporting of financial performance is either thorough, reliable, and accurate; or it isn’t. Therefore, most institutional investors have refined opinions about which audit firms are satisfactory and which aren’t.

And since those investors are ultimately the ones who write the checks—they don’t call it the “buy-side” for nothing—small public companies that are otherwise well-suited to begin evolving their shareholder base from retail investors to institutional investors have little choice but to pay attention to investor preferences.

However, this creates an interesting conundrum for many aspiring small-cap companies. Large public companies typically choose from a handful of audit firms that are all affordable, acceptable to institutional investors, and highly solicitous of their business. Small public companies choose from a seemingly endless list of audit firms, but, depending upon the size and health of the company, many of the firms that institutional investors are likely to favor are unaffordable and may decline to audit riskier, smaller companies.

Therefore, the selection process for many small-caps ends up being a Venn diagram with three principal inputs: affordability, the audit firm’s willingness to audit, and the firm’s reputation.

Two of the three inputs are easily gauged: an audit firm’s affordability and its willingness to audit the company. Reputation, however, is where many small public company audit committees struggle to find the appropriate barometer.

While an audit firm’s reputation means different things to different constituents, the reality is that one group’s opinion matters most…investors. Like it or not, a small-cap’s choice of audit firms can prove to be an impediment to widespread consideration by institutional investors. Really.

Developing a List of Candidate Firms

Although it would be nice if institutional investors collectively published a list of all the audit firms that were on their “approved” list, they don’t. But what small public company audit committees can do is to apply the same criteria for choosing an audit firm that institutional investors do in order to develop a list of candidate firms.

There are four principal criteria that institutional investors weigh when evaluating audit firms:

PCAOB/peer audits. One of the critical ways that audit firms develop good reputations with institutional investors is by having exceptional results from audits of their firm conducted by the Public Company Accounting Oversight Board and through peer review entities like the American Institute of Certified Public Accountants.

Regulators and media. When audit firms do their jobs well, they are typically not mentioned in the media or singled out by state and federal regulators. Therefore, the extent of the firm’s public profile is often inversely proportional to the regard in which the firm is held by institutional investors.

Industry expertise. Like all professional service providers, audit firms often distinguish themselves by demonstrating particular expertise in auditing certain industries.

Consensus. Institutional investors constantly compare notes with one another and pull together what they’ve witnessed, read, and heard.

Once a candidate pool is developed, don’t stumble at the final hurdle: consider going right to the source, and ask your largest investors if they have any input on the firms under consideration.

Poor Choices Have Real Repercussions

Because there are so many audit firms of such disparate quality that serve the small-cap markets, the choice of one firm over another can have material capital markets implications.

Think of it from the perspective of an institutional investor. Gauging the strengths, weaknesses, opportunities, and threats to any small-cap is perilous enough. To then layer on concerns about the integrity of audited financial statements not only creates a fundamental issue of valuation but an equally important matter of perception. Even if a particular company’s financial statements are perfectly accurate, a negative consensus about its audit firm among institutional investors is likely to create a negative feeling about the company’s stock. Therefore, wherever there are concerns about the quality and reputation of the audit firm, institutional investors will either invest less or not at all.

The point for officers and directors is that the two things that matter most to many small-caps—cost of capital and access to capital—can be significantly affected by the company’s selection of an audit firm that has an unsatisfactory reputation among institutional investors.

Companies that have institutional investors or that wish to shift their shareholder base from retail investors to institutional investors need to constantly reexamine whether their audit firm is the most institutional investor-friendly one that the company can attract and afford. The alternative—sticking with an audit firm strictly out of loyalty, comfort, or cost—won’t benefit shareholders.
