Pimco could face SEC action over bond ETF

The notice, which is not a formal allegation of wrongdoing, is related to a bond exchange-traded fund once managed by Bill Gross.

Pimco could face civil charges from the U.S. Securities and Exchange Commission related to its Total Return Active Exchange-Traded Fund, the bond giant said Monday.

The company received a "Wells Notice" from the SEC over the fund, which was once managed by Bill Gross. It is neither a formal allegation of wrongdoing nor a finding that a law was violated.

The agency may recommend civil action against Pimco related to the value of smaller positions in non-agency mortgage-backed securities the fund bought in 2012. A nonpublic investigation also looked into the fund's performance disclosures as well as compliance policies.

"The Wells process provides us with our opportunity to demonstrate to the SEC staff why we believe our conduct was appropriate, in keeping with industry standards, and that no action should be taken. We will continue to engage with the SEC and we are confident that this matter will not affect our ability to serve our clients," Pimco said in a statement Monday.

Gross left Pimco last year and now works at Janus Capital.
