Apollo Global Management will reduce Aviva USA staff by about 10 percent once it completes its purchase of the West Des Moines-based insurer, The Des Moines Register reported.
The private equity firm purchasing Aviva USA sent a letter to its future staffers Tuesday, outlining its intention to eliminate 154 positions, including 90 in Greater Des Moines. Aviva, which will be operated as Athene USA, currently employs approximately 1,500 people nationwide.

Most of the layoffs will occur in the company's operations, sales and distribution and information technology areas, the company said.
