This report presents the results of Milliman’s 2017 Annual Survey of the U.S. Individual Disability Income (IDI) Insurance Market. Fourteen insurance companies were surveyed about new business sold from 2002 through 2016, sales distributions, underwriting requirements, product offerings and pricing, favorable and unfavorable trends, and opportunities and obstacles affecting the IDI market. A new section has been added this year that discusses the progress IDI companies are making in implementing the 2013 IDI Valuation Table.
