Officials from Ameritas, the insurance company headquartered in Lincoln, announced Wednesday that three positions will be cut from the Lincoln office, part of 21 job cuts nationally at Ameritas and its affiliated Unifi Cos.

The layoffs are a result of the slow economy, said Scott Stuckey, vice president of corporate communications in Lincoln. He did not anticipate additional layoffs.

Stuckey said Wednesday's cuts were made across a variety of job titles. Ameritas and its affiliates employ 2,600 people nationwide.
