The Fund pursues its investment objective by investing, under normal circumstances, at least 80% of its net assets (plus any borrowings for investment purposes) in bonds. For purposes of this 80% policy, the term bonds refers to a variety of fixed-income securities and instruments of all types and maturities, including, but not limited to, mortgage-backed securities, asset-backed securities, corporate bonds, U.S. Treasury obligations, U.S. government and agency securities, commercial paper, loan interests, and funds that invest in short-term debt (such as money market funds). The Fund will invest principally in investment grade bonds. An investment grade bond is a fixed-income or other debt securityrated Baa3/BBB- or higher by a Nationally Recognized Statistical Ratings Organization ( NRSRO ) or, if unrated, determined tobe of comparable credit quality by Janus Capital. An NRSRO is a credit rating agency that is registered with the Securities and Exchange Commission ( SEC ) that issues credit ratings that the SEC permits other financial firms to use for certain regulatorypurposes. The Fund may also invest up to 5% of its assets in securities rated below investment grade (sometimes referred to as junk bonds), or, if unrated, determined to be of comparable credit quality by Janus Capital. The Fund may invest up to 20%of its net assets in foreign securities, which may include up to 5% in investments in emerging market securities. The Fund will only invest in U.S. dollar denominated securities. |
