The supervision lapses at Citigroup Global Markets Inc, which occurred between January 2005 and February 2014, included an instance in which the firm allowed one of its analysts to participate indirectly in two of its initiatives to promote clients’ initial public offerings to investors, the Financial Industry Regulatory Authority said.

Citigroup, which settled the allegations with FINRA, neither admitted nor denied the charges, but consented to the entry of FINRA’s findings.

“We are pleased to have resolved and put this matter behind us,” a Citigroup spokeswoman said in a statement. “Citi takes its regulatory compliance obligations seriously, and we believe we have strong procedures and controls in place to address the issues that FINRA has raised in this matter. We are continually working to improve those controls and procedures going forward,” the spokeswoman said.

Citigroup issued about 100 internal warnings about communications from equity research analysts during the period, FINRA said. But there were “lengthy delays” before Citigroup disciplined the analysts. What’s more, the disciplinary measures were not severe enough to deter more violations of Citigroup’s policies, FINRA said.

One example of Citigroup’s conduct involved dinners that equity research analysts hosted at which some institutional clients, as well as sales and trading employees, were guests. At the dinners, the analysts discussed stock picks that in some cases were not consistent with the research they published.

Citigroup did not give analysts adequate guidance on limits for their possible remarks, FINRA said.

In another instance, an analyst at a Taiwan-based Citigroup affiliate “selectively disseminated” research about Apple Inc to some clients, which a Citigroup equity sales employee then related, selectively, to other clients, FINRA said.
