What Citi's Mexico scandal says about SarbOx

Trouble at the big banker reminds us that the 2002 law did some good.

By Jack T. Ciesielski


FORTUNE -- Say what you want about the Sarbanes-Oxley Act -- and it's rare to hear anything positive said about it -- but since it was enacted in 2002, the routine incidence of corporate fraud has diminished. On an almost weekly basis during the early 2000s, monolithic firms like WorldCom and Enron, along with scores of lesser firms, proved to be dreams built upon mere vapors. Those wild and crazy days have long receded from investors' memories.

Did Sarbanes-Oxley outlaw fraud and imbue corporate America with enlightened honesty? Of course not. For all players in the financial reporting arena, the Act simply raised the stakes for acting badly. It mandated changes for auditors that made their oversight more painful by putting them under the thumb of the Public Company Accounting Oversight Board. It required companies to install basic accounting controls that allowed earlier detection of aberrant behavior and made life harder for fraudsters -- in total, demanding the kind of infrastructure nobody really cares about when they're high on the thrill of building a company through deal after deal.

The stakes were painfully raised for CEOs and CFOs, who now had to certify in the financial statements that they're responsible for establishing and maintaining such controls, and that those controls ensure that material information about the company and its subsidiaries gets to the right officers within the firm. There probably isn't a CEO or CFO in the country who hasn't flinched at least once when signing that certification -- and that requirement is probably making Citigroup's CEO Michael Corbat grind his teeth down to the gumline.

Citi's (C) fourth-quarter after-tax earnings restatement of $235 million didn't matter according to the market: The stock closed a mere six cents lower on Friday when news broke of the scandal at the bank's Mexican subsidiary, Banamex. Yet the announcement contained a couple of peculiarities, one related to Sarbanes-Oxley, and one that shows how companies need to go beyond that law's requirements.

Thus far, Citi has ascertained that the fraud amounted to $400 million of bogus receivables financed by its Banamex subsidiary for Oceanografia S.A., a Mexican oil services company, ostensibly to help speed up cash flow from OSA's customer, Pemex, the Mexican state-owned oil company. This accounts receivable financing program took place over several years -- but Citigroup apparently became suspicious only when it learned of OSA's suspension from bidding on new Pemex contracts. If the SarbOx-style internal controls were in place to ensure that material information in the firm was getting to the right officers, should it really take years to find out that $400 million of receivables are worthless?

Sarbanes-Oxley provided disincentives for managers to behave badly, but there's an incentive issue at work in the Citi episode that counters good internal controls. The company's press release notes that while Banamex's airy loans amounted to $400 million, the pretax charge was reduced by "an offset to compensation expense of approximately $40 million associated with the Banamex variable compensation plan." In other words, some Banamex employees could earn a 10% bonus for making poor loans and keeping them on the books, or maybe even by making loans out of thin air. Evidently there was an incentive at work to present false financial information, and not enough of a disincentive to prevent bad behavior.

No doubt, Mr. Corbat will make some very visible examples of the managers who allowed this to happen. It's hard not to expect this kind of thing to erupt again, though -- maybe at Citi, maybe at another giant bank. These banks push the limits of the span of control that managers can actually handle. They're not just too big to fail -- they might be too big to manage, too.

  • The GM conflict of interest that wasn't

    A few days before General Motors (GM) went public, an investor called me to say that the company was in violation of Sarbanes-Oxley. Specifically, he said that a member of the automaker's audit committee was not adequately independent.

    Juicy story – a state-owned company violating federal law. But my source was wrong. GM was not violating either Sarbanes-Oxley or NYSE listing requirements. It was just violating their spirit, in a way MORE

    Is financial reform putting too much emphasis on shareholders who aren't there for the long haul?

    One potential irony of financial reform: Would instituting new rules to limit short-term decision-making in the boardroom lead us to favor those who make short-term decisions in the markets?

    The financial reform bill, it turns out, comes down squarely on the side of shareholders as the ultimate power. Since the 1930s, corporate MORE
