Auth and Keenan Power a $71B-AUM AM's 9th ETF

The folks at a $71-billion-AUM*, 48-year-old mutual fund firm in Massachusetts are rolling out their ninth ETF, which is also their 2nd fixed income ETF.

Last week, Joe Auth, head of developed fixed income at GMO [profile], and Tracey Keenan, head of short duration strategies, unveiled the launch of the GMO Ultra-Short Income ETF (GMOC on the NYSE Arca, Inc.). Boston-based Grantham, Mayo, Van Otterloo & Co. LLC serves as investment advisor to the new fund.

GMOC's inception date was last Monday, October 27. The new ETF comes with an expense ratio of 20 basis points.

Keenan and Auth are GMOC's PM team. The same duo also serves as portfolio managers of an existing institutional version of the same strategy.

Auth describes GMOC as designed to address "the growing need for sophisticated liquidity management solutions."

"By focusing on the safest, highest-quality segment of the CLO market, combined with GMO's credit expertise, we believe we can offer compelling risk-adjusted returns for investors seeking to enhance their liquid holdings," Auth states.

"Our approach provides flexibility and efficiencies by optimizing capital deployment for higher returns, without taking excessive credit or duration risk," Keenan states.

GMOC is an actively managed series of GMO ETF Trust. The new ETF's other service providers include:

ACA's Foreside Fund Services, LLC as distributor;

PricewaterhouseCoopers LLP as independent accounting firm;

Ropes & Gray LLP as counsel; and

State Street Bank & Trust Company as administrator, custodian, dividend disbursing agent, and transfer agent.
