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 U.S. dollar denominated corporate bonds and commercial paper of various maturities. Under normal circumstances, no more than 15% of the Funds net assets will be invested in securities rated below investment grade(sometimes referred to as junk bonds); however, such bonds will have a minimum rating of B- by a Nationally Recognized StatisticalRatings Organization (NRSRO) or, if unrated, determined to be of comparable credit quality by Janus Capital. The Fund seeks toinvest in debt instruments issued by companies that Janus Capitalbelieves exhibit sustainable business practices. As discussed furtherbelow, the portfolio managers seek to select securities that alignwith certain positive social and environmental themes. In identifyinginvestment opportunities for the Fund, the portfolio managers use a proprietary multi-factor sustainability framework, along with ananalysis of fundamental business and credit quality factors, to guide both security selection and overall portfolio composition. Thesustainability framework incorporates thematic investing, exclusions, positive tilting, sector- and issuer-level environmental, social andgovernance factor analysis and issuer engagement considerations as determined by Janus Capital, as discussed further below. The Fundmay, but is not required to, invest in so-called labeled bonds, which include debt where the proceeds have been specificallyearmarked for ESG-themed purposes (Use of Proceeds bonds), or the returns are specifically tied to defined sustainable orenvironmental key performance indicators (KPI-linked bonds)
