MFS Investment Management has filed paperwork with the Securities and Exchange Commission to launch a pair of mutual funds in September.

First, the firm is looking to launch the MFS High Yield Pooled on Sept. 12. The fund will primarily bet on high-income debt and can invest up to 100% in below-investment-grade bonds, according to a filing to launch. David Cole and William Adams are the portfolio managers of the fund.

The firm has also filed to launch the MFS Equity Income fund on Sept. 30. The fund will bet on dividend-paying common stocks and will be managed by Jonathan Sage.

A spokesman for the firm declined to comment on the new offerings.
