The Fund is an actively-managed exchanged-traded fund (ETF) that seeks to achieve its investment objective by investing in ETFs that provide unleveraged or leveraged exposure to the S&P 500 Index, depending on trading signals from proprietary models used by the Fund's investment adviser, Miller Value Partners, LLC (the Adviser), to implement the Fund's investment strategy. When the Adviser's trading signals indicate that the Fund should be in an unleveraged (or leverage off) position, the Fund will invest its assets in an ETF that seeks to track the performance of the Index (Unleveraged ETF). Currently, the Unleveraged ETF the Fund intends to invest in when in an unleveraged position is SPDR S&P 500 ETF (ticker: SPY). When the Advisers trading signals indicate that the Fund should be in a leveraged (or leverage on) position, the Fund will invest its assets in an ETF that seeks investment results that correspond to two times the performance of the Index on a daily basis (Leveraged ETF). Currently, the Leveraged ETF the Fund intends to invest in when in a leveraged position is the ProShares Ultra S&P 500 ETF (ticker: SSO). An Unleveraged ETF or a Leveraged ETF may also be referred to herein as an Underlying ETF. The Adviser's proprietary models provide daily trading signals based on certain technical data for the Index (e.g., price changes, valuation metrics, and volatility measures, among others discussed below) to determine whether to implement the Funds investment strategy in a leveraged or unleveraged position on a daily basis. The Fund will seek to capitalize on the Index's propensity to increase in value over long time horizons by opportunistically timing the use of leverage when the trading signals indicate conditions are favorable for the Fund to be in a leverage on position. Such opportunistic use of leverage (as contrasted with an investment that is continuously in a leverage on position) should help to minimize the probability that decreases or volatility in the value of the Index will cause permanent loss of capital. The Index is a float-adjusted, market-capitalization weighted index that includes the stocks of the 500 leading U.S.-listed large-cap issuers. The Index is constructed by S&P Dow Jones Indices LLC. It is not possible to invest in the Index directly. As of June 30, 2023, the Index consisted of 500 constituents and was concentrated in the information technology sector. The Index is rebalanced quarterly. The Fund will be concentrated in an industry or group of industries to the extent the Index is concentrated in an industry or group of industries.
