abrdn Bloomberg All Commodity Strategy K-1 Free ETF (BCI) Exchange: NYSE ARCA

The Fund is an actively managed exchange-traded fund (“ETF”) that is not required to track the Index or invest in all of the Index’s components. However, the Fund will generally seek to hold similar interests to those included in the Index and will seek exposure to many of the commodities included in the Index under the same futures rolling schedule as the Index. The Fund will also hold short-term fixed-income securities, which may be used as collateral for the Fund’s commodities futures holdings or to generate interest income and capital appreciation on the cash balances arising from its use of futures contracts (thereby providing a “total return” investment in the underlying commodities). Under normal market conditions, the Fund intends to achieve its investment objective by investing in exchange-traded commodity futures contracts through a wholly-owned subsidiary of the Fund organized under the laws of the Cayman Islands (the “Subsidiary”). As a means to provide investment returns that are highly correlated to those of the Index, the Subsidiary may also invest directly in commodity-linked instruments, including pooled investment vehicles (such as exchange-traded funds and other investment companies), swaps and exchange-traded options on futures contracts, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”) and any applicable exemptive relief (collectively, “Commodities-Related Assets” and, together with exchange-traded commodities futures contracts, “Commodities Instruments”). The Fund may invest up to 25% of its total assets in the Subsidiary. The remainder of the Fund’s assets that are not invested in the Subsidiary (i.e., at least 75% of the Fund’s total assets) will principally be invested in: (1) short-term investment grade fixed-income securities that include U.S. government securities and money market instruments; and (2) cash and other cash equivalents. The Fund will exercise its discretion to use such instruments to most efficiently utilize the cash balances arising from the use of futures contracts and generate a total return for investors. As noted previously, the Fund will not invest directly in commodity futures contracts but, instead, expects to gain exposure to these investments exclusively by investing in the Subsidiary. The Fund’s investment in the Subsidiary is intended to enable the Fund to gain exposure to relevant commodity markets within the limits of current federal income tax laws applicable to a regulated investment company (“RIC”) such as the Fund, which limit the ability of RICs to invest directly in commodity futures contracts. The Subsidiary and the Fund have the same investment objective. However, the Subsidiary may invest without limitation in the Commodities Instruments. Except as otherwise noted, for the purposes of this Prospectus, references to the Fund’s investments include the Fund’s indirect investments through the Subsidiary. The Advisor and Sub-Advisor will use their discretion to determine the percentage of the Fund’s assets allocated to the Commodities Instruments held by the Subsidiary that will be invested in exchange-traded commodity futures contracts or Commodities-Related Assets. In this regard, under normal market conditions, the Subsidiary is expected to invest in futures contracts in proportional weights and allocations that are similar to the Index. The Fund does not seek leveraged returns. However, the Fund’s use of instruments to collateralize the Subsidiary’s investments in Commodity Instruments has a leveraging effect and is designed to provide a total return. The Index is a widely followed commodity index which is calculated and published by Bloomberg L.P. and/or Bloomberg Finance L.P. and/or an affiliate of them (together, “Bloomberg”). The Index has been published since 1998 with simulated historical performance calculated back to 1991 and tracks movements in the price of a rolling position in a basket of commodity futures with a maturity between 1 and 3 months. At present, there are 25 commodity futures eligible for inclusion in the Index but four of those commodities (cocoa, lead, platinum and tin) are currently not included in the Index. With the exception of certain metals contracts (aluminum, lead, tin, nickel and zinc) that trade on the London Metals Exchange (“LME”) and the contracts for Brent crude oil and low sulphur gas oil, each of the Commodities is the subject of at least one futures contract that trades on a U.S. exchange. The Index uses a consistent, systematic process to represent the commodity markets using both liquidity data and U.S. dollar-weighted production data in determining the weightings of included commodities. Liquidity data is the relative amount of trading activity for a particular commodity and U.S. dollar-weighted production data takes the figures for production in the overall commodities market for all commodities in the Index and weights them in the Index in the same proportion in U.S. dollar terms. The value of the Index is computed on the basis of hypothetical investments in the basket of commodities that make up the Index. The Index invests significantly in, and therefore the Fund has significant exposure to, the agriculture, energy and industrial/precious metals sectors. The Index is rebalanced annually starting on the fifth business day of January. The Fund is classified as “non-diversified” under the 1940 Act.
