Management’s Discussion of Fund Performance
Summary of Results
The Fund outperformed the Bloomberg U.S. Government 1-3 Year Bond Index (the “Bloomberg Index”) for the period. The Fund’s Class A shares delivered a total return on net asset value of 1.33%, versus a 0.64% return for the Bloomberg Index.

The Fund’s investment strategy, under normal circumstances, is to invest exclusively in U.S. Government securities and repurchase agreements, collateralized by U.S. Government securities, with a weighted average maturity (“life”) of three years or less. The Fund maintained a weighted average life of 2.98 years during the period. The Fund remains mostly invested in mortgage-backed securities (“MBS”).
Market Overview
  • Bloomberg Index consisted of approximately 250 holdings at the end of the period, all of which were Treasuries and Agencies
  • MBS outperformed both Treasuries and Agencies during the period
Contributors to Performance
  • Performance benefited primarily due to large position (average weighting of 51%) in Collateralized Mortgage Obligations (“CMOs”)
    • What is a CMO? - a type of mortgage-backed security that contains a pool of mortgages bundled together and sold as an investment
  • SBA (Small Business Administration) loan position (average weighting of 19%)
    • What is an SBA loan? - a type of financing backed by the Small Business Administration that helps small businesses purchase, build, or improve real estate
  • MBS pass-through position (average weighting of 23%)
    • What is MBS pass-through? - issuer collects monthly payments from a pool of mortgages and then passes on a proportionate share of the collected principal and interest to bondholders
Detractors from Performance
  • Relative performance hindered slightly by 7% average position in repurchase agreements (cash)
  • Impact from Fund expenses - Bloomberg Index does not charge expenses
Performance Past Does Not Indicate Future [Text] The Fund's past performance is not a good predictor of how the Fund will perform in the future.

Summary of Results
The Fund outperformed the Bloomberg U.S. Government 1-3 Year Bond Index (the “Bloomberg Index”) for the period. The Fund’s Class Y shares delivered a total return of 1.46%, versus a 0.64% return for the Bloomberg Index.

The Fund’s investment strategy, under normal circumstances, is to invest exclusively in U.S. Government securities and repurchase agreements, collateralized by U.S. Government securities, with a weighted average maturity (“life”) of three years or less. The Fund maintained a weighted average life of 2.98 years during the period. The Fund remains mostly invested in mortgage-backed securities (“MBS”).
Market Overview
  • Bloomberg Index consisted of approximately 250 holdings at the end of the period, all of which were Treasuries and Agencies
  • MBS outperformed both Treasuries and Agencies during the period
Contributors to Performance
  • Performance benefited primarily due to large position (average weighting of 51%) in Collateralized Mortgage Obligations (“CMOs”)
    • What is a CMO? - a type of mortgage-backed security that contains a pool of mortgages bundled together and sold as an investment
  • SBA (Small Business Administration) loan position (average weighting of 19%)
    • What is an SBA loan? - a type of financing backed by the Small Business Administration that helps small businesses purchase, build, or improve real estate
  • MBS pass-through position (average weighting of 23%)
    • What is MBS pass-through? - issuer collects monthly payments from a pool of mortgages and then passes on a proportionate share of the collected principal and interest to bondholders
Detractors from Performance
  • Relative performance hindered slightly by 7% average position in repurchase agreements (cash)
  • Impact from Fund expenses - Bloomberg Index does not charge expenses
Performance Past Does Not Indicate Future [Text] The Fund's past performance is not a good predictor of how the Fund will perform in the future.
