Index represents the Bloomberg Barclays 1-3 Year U.S. Government/Credit Index. Holdings are subject to change without notice. For a complete list of holdings as of the most recent publicly available disclosure period, visit janus.com/advisor/mutual-funds. Equity country, regional, sector and industry weights based on MSCI and GICS classifications. Fixed income country, regional, sector and industry weights based on Barclays classifications. Performance may be affected by risks that include those associated with non-diversification, portfolio turnover, short sales, potential conflicts of interest, foreign and emerging markets, initial public offerings (IPOs), high-yield and high-risk securities, undervalued, overlooked and smaller capitalization companies, real estate related securities including Real Estate Investment Trusts (REITs), derivatives, and commodity-linked investments. Each product has different risks. Please see the prospectus for more information about risks, holdings and other details. Foreign securities are subject to additional risks including currency fluctuations, political and economic uncertainty, increased volatility, lower liquidity and differing financial and information reporting standards, all of which are magnified in emerging markets. Fixed income securities are subject to interest rate, inflation, credit and default risk. The bond market is volatile. As interest rates rise, bond prices usually fall, and vice versa. The return of principal is not guaranteed, and prices may decline if an issuer fails to make timely payments or its credit strength weakens. High-yield/high-risk bonds, also known as "junk" bonds, involve a greater risk of default and price volatility than U.S. Government and other high quality bonds. High-yield/high-risk bonds can experience sudden and sharp price swings which will affect net asset value. Index performance does not reflect the expenses of managing a portfolio as an index is unmanaged and not available for direct investment. Bloomberg Barclays 1-3 Year U.S. Government/Credit Index measures Treasuries, government-related issues and corporates with maturity between 1-3 years. Alpha compares risk-adjusted performance relative to an index. Positive alpha means outperformance on a risk-adjusted basis. Beta measures the volatility of a security or portfolio relative to an index. Less than one means lower volatility than the index; more than one means greater volatility. R-Squared (R2) measures the relationship between portfolio and index performance on a scale of 0.00 (0%) to 1.00 (100%). A higher R2 indicates more of the portfolio's performance is affected by market movements and vice versa. Standard Deviation measures historical volatility. Higher standard deviation implies greater volatility. Sharpe Ratio measures risk-adjusted performance using excess returns versus the "risk-free" rate and the volatility of those returns. A higher ratio means better return per unit of risk.
