Fixed income securities and other debt instruments include corporate bonds, including high yield bonds, commercial paper, debt securities issued or guaranteed by the U.S. government and its agencies and instrumentalities, Treasury Inflation-Protected Securities (TIPS), municipal bonds, bank loans, mortgage- and asset-backed securities and convertible securities. Barrow, Hanley, Mewhinney & Strauss, LLC (the Sub-Adviser or Barrow Hanley), the Funds sub-adviser, believes investing in undervalued securities with above-average yield to maturity and capital appreciation potential has the potential to generate above-average returns over the long term while minimizing volatility and, therefore, downside risk. Using this approach, Barrow Hanley seeks to construct a portfolio of U.S. investment grade fixed income securities with diversified maturities. Barrow Hanleys analysis of the credit quality of fixed income securities and other debt instruments looks at cash flow, earnings, and balance sheet fundamentals, as well as any supply/demand factors that Barrow Hanley believes will impact the future credit rating of the issuer and the yield premium. A significant focus in Barrow Hanleys credit research is identifying the credits that have a greater probability of ratings upgrades while avoiding downgrades. Barrow Hanley reviews the financial statements and Securities and Exchange Commission filings of companies, analyzing, among other factors, the following fundamental factors in the selection process: ? Managements stated business goals are reviewed for reasonableness and consistency. ? The ability to pay down debt with free cash flow. ? Profitability measures compared to similarly rated companies for return on equity, return on capital, and return on investment. ? Revenue and earnings growth, including margin trends in operating earnings. ? Various credit measures, including EBITDA, selling, general and administrative (SG&A) expenses, leverage, and interest coverage ratios, both absolute and trends. ?
