Janus Henderson Small Cap Growth Alpha ETF (JSML) Exchange: NASDAQ

The Fund pursues its investment objective by normally investing at least 80% of its net assets (plus any borrowings for investment purposes) in the securities that comprise the Janus Henderson Small Cap Growth Alpha Index (“Underlying Index”).The Underlying Index is composed of common stocks of small-sized companies that are included in the Solactive Small Cap Index, a universe of 2,000 small-sized capitalization stocks. The Solactive Small Cap Index uses the total public market value, or “free-float,” capitalization of a stock to determine whether to include such stock in the Solactive Small Cap Index. The Underlying Index is designed to select small-sized capitalization stocks that are poised for “smart growth” by evaluating each company’s performance in three critical areas: growth, profitability, and capital efficiency. Using a proprietary quantitative methodology, such stocks are scored based on fundamental measures of their growth, profitability, and capital efficiency, and the top 10% of such eligible stocks scoring the highest become the constituents of the Underlying Index. To arrive at the top 10%, for each security in the stated universe, the quantitative methodology assigns a score in each of 10 different fundamental factors, relative to other eligible securities. The fundamental factors include measures that Janus Capital believes are tied to a stock’s outperformance relative to other small cap stocks, and indicate a company’s performance with respect to growth (such as the revenue growth rate over 2- 5- and 8- year periods), profitability (such as margin expansion, profit margin and earnings per share over time) and capital efficiency (such as returns on invested capital). The scores for each stock within a factor are then added together across the 10 factors, with equal weighting, to arrive at an overall score for each stock. The stocks with the highest 10% of scores are then weighted within the Underlying Index according to their market capitalization. Finally, the stocks are sector-weighted to reflect the sector allocation weight of Janus Henderson Venture Fund, based on its most recent publicly available holdings. A stock may not represent more than 3% of the Underlying Index. The Underlying Index seeks risk adjusted outperformance relative to a market capitalization weighted universe of small-sized capitalization growth stocks. Market capitalizations within the Underlying Index will vary, but as of February 1, 2020, they ranged from approximately $94 million to $3.3 billion. The Underlying Index is rebalanced on a quarterly basis based on the methodology described above.The Fund uses a “passive,” index-based approach in seeking performance that corresponds to the performance of the Underlying Index. The Fund generally will use a replication methodology, meaning it will invest in the securities composing the Underlying Index in proportion to the weightings in the Underlying Index. However, the Fund may utilize a sampling methodology under various circumstances in which it may not be possible or practicable to purchase all of the securities in the Underlying Index. Janus Capital expects that over time, if the Fund has sufficient assets, the correlation between the Fund’s performance, before fees and expenses, and that of the Underlying Index will be 95% or better. A figure of 100% would indicate perfect correlation.The Fund may also invest in investments that are not included in the Underlying Index, but which Janus Capital believes will help the Fund track the Underlying Index. Such investments include stocks, shares of other investment companies, cash and cash equivalents, including money market funds.To the extent the Underlying Index concentrates (i.e., holds 25% or more of its total assets) in the securities of a particular industry or group of industries, the Fund will concentrate its investments to approximately the same extent as the Underlying Index. As of February 1, 2020, the Underlying Index did not concentrate in a particular industry or group of industries. For more recent information, see the Fund’s daily portfolio holdings posted on the ETF portion of the Janus Henderson website.The Fund may lend portfolio securities on a short-term or long-term basis, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination.The Underlying Index is compiled and administered by Janus Henderson Indices LLC (“JH Indices” or the “Index Provider”).
