The six Ave Maria Mutual Funds are managed by Plymouth, Michigan-based Schwartz Investment Counsel, Inc.
According to the fund family prospectus and website, the company screens its investments first on financial criteria.
They have a preference for contrarian and value strategies, and companies with low debt levels for their type or sector.
Involvement with contraception and abortion also disqualify a company from the fund, as does embryonic stem cell research.
Unlike some other ethical funds, Ave Maria does not necessarily reject companies involved in military contracting or the defense industry, alcohol, or tobacco.
