An additional 326 workers at Aviva USA will lose their jobs over the next two years, The Des Moines Register reported. That number is in addition to about 300 Aviva employees who have left voluntarily and another 154 who were notified last week that they would be laid off. Apollo Global Management, which has purchased Aviva USA and will operate the company as Athene USA, said the additional cuts are necessary because some existing administrative duties now handled by its life insurance arm will be outsourced. Athene President Grant Kvalheim said the outsourcing decision was made by Global Atlantic Financial Group, the company that's purchasing Aviva's life insurance business. With the latest reductions, 43 percent of Aviva USA's 1,800 employees will have either voluntarily left the company or have been notified that their jobs will be eliminated, the Register reported.
