An investigation by the U.S. Securities and Exchange Commission’s (SEC) internal affairs division was unable to pin down the source of a leak of confidential information from a closed-door commission meeting, but it did uncover a couple of violations of its communications policies, according to a report released Monday.

In response to a Freedom of Information request, the SEC released a report prepared by its Office of Inspector General (OIG) into the possible unauthorized disclosure of non-public information from a closed commission meeting. The issue was raised by commissioner Michael Piwowar with SEC chair Mary Jo White, concerning the regulator’s deliberations and vote on a possible settlement agreement with J.P. Morgan in an enforcement case; the details of which were reported by Reuters in September 2013.

Following a vote to approve the deal, the SEC settled with J.P. Morgan over allegations that it lacked effective internal controls stemming from the so-called “London Whale” case, which resulted in several billion dollars in trading losses for the firm. As part of the settlement, the firm agreed to pay a $200 million penalty to the SEC.

The report says that the OIG “was unable to conclude which specific individual or individuals had improperly disclosed information” from a commission meeting about the case. However, it says that it did find that a commissioner and several staff members had separately spoken with Reuters reporters around the time that the information was improperly disclosed. The OIG report also says that one of those employees may have confirmed certain information to the reporters.

While it wasn’t about to identify the source of the improper disclosure involving the JP Morgan case, the report indicates that during the course of its investigation, the OIG discovered a couple of unrelated concerns about the handling of non-public information.

It reports that it found that commissioner Luis Aguliar transmitted non-public information over non-secure email; and, that one employee may have improperly conducted commission business using his personal email. Specifically, the report indicates that Aguilar told investigators that he forwarded emails to his personal account when he needed to print certain documents at home. It says “he did not view sending nonpublic SEC information to his personal email account as a problem and was not aware that doing so violated [SEC policy].”

The investigation involved interviews of the SEC chair, commissioners, and 48 employees; it reviewed emails and BlackBerry records from 39 employees; and, examined their phone records. The reporters involved declined to be interviewed, it says.
