On Thursday, the Consumer Financial Protection Bureau (CFPB) took action against Experian and its subsidiaries for what regulators said was “deceiving” consumers about the use of credit scores it sold to consumers.

The CFPB said Experian claimed the credit scores it marketed and provided to consumers were used by lenders to make credit decisions. The regulator found lenders did not use Experian’s scores to make those decisions.

The CFPB ordered Experian to “truthfully” represent how its credit scores are used. Experian must also pay a civil penalty of $3 million.

“Experian deceived consumers over how the credit scores it marketed and sold were used by lenders,” CFPB director Richard Cordray said. “Consumers deserve and should expect honest and accurate information about their credit scores, which are central to their financial lives.”

Experian, based in Costa Mesa, Calif., is one of the nation’s three largest credit reporting agencies. Experian markets, advertises, sells, offers and provides credit scores, credit reports, credit monitoring and other related products to consumers and third parties.

As finance companies know, credit scores are numerical summaries designed to predict consumer payment behavior in using credit. Many lenders and other commercial users consider these scores when deciding whether to extend credit.

The CFPB emphasized no single credit score or credit scoring model is used by every lender.

In addition to the credit scores that are actually used by lenders, the regulator said several companies have developed so-called “educational credit scores,” which lenders rarely, if ever, use. These scores are intended to inform consumers.

The CFPB recapped Experian developed its own proprietary credit scoring model, referred to as the “PLUS Score,” which it applied to information in consumer credit files to generate a credit score it offered directly to consumers. The PLUS Score is an “educational” credit score and is not used by lenders for credit decisions.

From at least 2012 through 2014, the CFPB charged that Experian violated the Dodd-Frank Wall Street Reform and Consumer Protection Act by “deceiving” consumers about the use of the credit scores it sold.

“In its advertising, Experian falsely represented that the credit scores it marketed and provided to consumers were the same scores lenders use to make credit decisions,” the CFPB said. “In fact, lenders did not use the scores Experian sold to consumers.

“In some instances, there were significant differences between the PLUS Scores that Experian provided to consumers and the various credit scores lenders actually use. As a result, Experian’s credit scores in these instances presented an inaccurate picture of how lenders assessed consumer creditworthiness,” the CFPB continued.

The regulator went on to state Experian also violated the Fair Credit Reporting Act, which requires a credit reporting company to provide a free credit report once every 12 months and to operate a central source — AnnualCreditReport.com — where consumers can obtain their report.

Until March 2014, the CFPB found that consumers getting their report through Experian had to view Experian advertisements before they got to the report. The regulator said this practice violates the Fair Credit Reporting Act prohibition of such advertising tactics.

Under the Dodd-Frank Wall Street Reform and Consumer Protection Act, the CFPB is authorized to take action against institutions engaged in unfair, deceptive, or abusive acts or practices, or that otherwise violate federal consumer financial laws. Under the consent order, Experian must:

—Pay a $3 million penalty: Experian must pay a civil money penalty of $3 million to the bureau’s civil penalty fund.

—Truthfully represent the usefulness of credit scores it sells: Experian must inform consumers about the nature of the scores it sells to consumers.

—Put in place an effective compliance management system: Experian must develop and implement a plan to make sure its advertising practices relating to credit scores and on Internet webpages that consumers access through AnnualCreditReport.com comply with federal consumer laws and the terms of the CFPB’s consent order.
