Fund Overview
Adviser: Mason Street Advisors, LLC
Subadviser: Wells Capital Management, Inc.
Objective/Focus: Invests primarily in investment grade corporate, U.S. Treasury and government agency bonds and mortgage- and asset-backed securities. The objective is to provide as high a level of total return as is consistent with prudent investment risk. A secondary objective is preservation of capital.
Asset Class: Bond
Style: High Credit Quality, Moderate Interest Rate Sensitivity
Bonds and other debt obligations are affected by changes in interest rates, inflation risk and the creditworthiness of their issuers. High yield bonds generally have greater price swings and higher default risks than investment grade bonds. Return of principal is not guaranteed. In contrast to owning individual bonds, there are ongoing fees and expenses associated with owning shares of bond funds.
