The Fund

The Fund is a sub-fund of UBS (Irl) Alternative Solutions plc, which, as of the date of this Supplement to the Prospectus, has two other sub-funds, namely the O’Connor Opportunistic UCITS Fund and the O’Connor Opportunistic II UCITS Fund.

The Base Currency of the Fund is USD and the Class Currency of each Class is designated in the name of each Class, as described in the section entitled “Class Structure” in the Prospectus. In addition, as also described in the section entitled “Class Structure” in the Prospectus, Classes which have “hedged” in their name will be hedged to minimise the effect that fluctuations in the exchange rate between the relevant Class Currency and the Base Currency may have on the performance of the Shares of those Classes, relative to the performance of Shares in the Base Currency, as described in the paragraph entitled “Foreign Exchange Hedging” in the section “Investment Objective” of the Prospectus.

As at the date of this Supplement, the following categories of Shares of the Fund are available for investment: Class P, Class K-1, Class Q, Class I-A1, Class I-A2, Class I-A3, Class I-X, Class U-A and Class U-X. Please see the section of the Prospectus entitled “Class Structure” to see the various Classes available in these categories. Shares are no longer available in the Founder Class and the Accelerator Class.

Application may be made for all Shares to be admitted to the Official List and to trading on the Main Securities Market of the Irish Stock Exchange. The Directors do not anticipate that an active secondary market will develop in the Shares.

As at the date of this Supplement, all of the Classes available for issue are accumulation Classes, within which every currency and hedging designation is available as detailed in the section of the Prospectus entitled “Class Structure”. The Company (on behalf of the Fund) may in the future issue one or more Classes which pay dividends, in which case this Supplement will be updated appropriately.

The Platform Manager intends to appoint one or more service providers (each a “Collateral Administrator”) to assist the Platform Manager in administering and executing, on a non-discretionary basis, the margin requirementsof the Fund’s brokers and trading counterparties. These services include calculating the Fund’s margin requirement, valuing and delivering margin to applicable trading counterparties, accepting margin from trading counterparties and facilitating substitutions of eligible margin. The terms of each such appointment are expected to contain limitations on liability and indemnities operating in favour of the Collateral Administrator in the absence of such Collateral Administrator’s fraud, negligence and wilful default and may, in certain cases, cap the Collateral Administrator’s liability in the event of its negligence. The Platform Manager has appointed the Administrator as the first Collateral Administrator and will pay fees of the Administrator in this context out of its own fees.

The Directors may, without notice to Shareholders and with the approval of the Central Bank, create additional Classes in the Fund, including Classes that are subject to fee arrangements and/or other terms that are different from those of any Class being offered hereby or then outstanding, including, without limitation, Classes of Shares which are made available solely to certain entities affiliated with the Platform Manager and/or Investment Manager.

The Company may also issue different Classes with the same characteristics but which are subject to different fees.

The Directors may apply for reporting fund status for the Shares in the United Kingdom. It cannot be guaranteed, however, that such status will be sought or obtained. If sought and obtained, it cannot be guaranteed that reporting fund status will be maintained. Investors should refer to the Section entitled “Shareholders in Classes with Reporting Fund Status” under “12.3 Taxation of the Company in the United Kingdom” in the Prospectus which outlines the United Kingdom taxation consequences and risks should reporting fund status be obtained.

Some or all of the Classes of the Fund may, in the future, be registered for public sale in certain countries. Further information in this regardcanbe requested from the Distributor.

A separate pool of assets will not be maintained for each Class.

The Fund may not issue all Classes listed in this Supplement. Information in relation to the Classes available for subscription at any time is available on request from the Distributor or the Administrator.

Profile of a typical investor: The Fund is suitable for investors seeking an actively managed portfolio, combined with diversification across investment strategies, asset classes and geographies. The Fund is suitable for investors who can afford to set aside the capital for the medium to long term and who seek medium to high investment risk. The Fund provides exposure to investment strategies with medium to high volatility and no capital protection strategies. As an investment in the Fund is designed to be a medium to long term investment, investors should not expect to obtain short-term gains from such investment.

4Investment Objective, Investment Policy and Investment Restrictions

Investment Objective

The Investment Objective of the Fund is to achieve a positive risk-adjusted return over the medium to long term, irrespective of market conditions. There can be no assurance that the Fund will achieve its investment objective or be profitable.

Investors should note that the Fund may seek to achieve its investment objective by investing primarily in Financial Derivative Instruments (FDI), as described below, which may be complex and sophisticated in nature, as well as in Eligible Collective Investment Schemes. An investment in the Fund is not in the nature of a deposit in a bank account and is not protected by any government, government agency or other guarantee scheme which may be available to protect the holder of a bank deposit account. An investment in the Fund should not constitute a substantial proportion of an investment portfolio and may not be appropriate for all investors.

Investment Policy

The Fund seeks to achieve its investment objective primarily by investing in a portfolio of systematic strategies and, up to 10% of its Net Asset Value, in Eligible Collective Investment Schemes. The Fund will also allocate a portion of its assets to a hedging overlay component as described below under “Hedging overlay component”. The systematic strategies provide exposures to factors that can be grouped broadly in the following categories: momentum, carry, value, quality, liquidity, event, hedging, and multi-strategy and will be implemented with respect to a range of asset classes, as described below (namely equities, fixed income, commodity indices, currencies and credit). These systematic strategies will be implemented through the use of FDIs as described in the “Financial instruments used in the investment strategies” section belowand the use of structured financial instruments as described in the “Structured Financial Instruments” section below. The Fund has no specific bias towards any particular factor, underlying asset class, country or region and, subject to the investment restrictions, its investments may be listed or traded on any Regulated Market globally.

Systematic strategies

The Fund will take exposure to certain systematic strategies. Exposure to the systematic strategies will be implemented synthetically, through derivative instruments (with underlyings across a range of asset classes including equities, fixed income, commodity indices, currencies and credit) and structured financial instruments (described below). The strategies to which exposure is taken are developed by the relevant counterparty, agreed to in advance by the Investment Manager and may or may not be proprietary. However, they will be completely rules based and systematic and the only party with discretion over the exposures taken thereto by the Fund is the Investment Manager. Exposure to commodities will be achieved through exposure to commodity indices that have been cleared in advance by the Central Bank for use by UCITS.

The systematic strategies can be broken down into the following categories: Momentum, Carry, Value, Quality Liquidity Event, Hedging and Multi-Strategy. As detailed below under “Financial instruments used in the investment strategies”, exposure to the assets comprising the systematic strategies will be provided through the use of total return swaps and portfolio swaps.Exposure to the systematic strategies will be provided through the use of structured financial instruments (described below).

Momentum: A Momentum, or trend, strategy exploits the tendency for an asset's recent relative positive or negative performance to continue into the near future. A strategy to exploit this serial correlation effect will take long exposures to the rising assets and synthetically short exposures to those that have declined. An example would be to take a synthetic short position in respect of equities which have declined in value in the expectation that the trend would continue. Momentum positions can be invested in the time series of a single asset or cross-sectionally within an asset class.
