reduce the Employers matching contributions. If there are no Employer matching contributions or there are excess forfeitures after the match is funded, such forfeitures will be allocated as an additional profit sharing contribution.



Any remaining forfeitures of matching
contributions will be used to pay reasonable plan expenses and any excess will be used to reduce the Employers matching contributions. If there are no Employer matching contributions, such forfeitures will be allocated as an additional profit
