Investment Objective & Policy The aim of the BlackRock UK Special Situations Fund (the Fund ) is to achieve long-term capital growth for investors. The Fund invests primarily in the shares of companies incorporated or listed in the UK and will normally have an emphasis on small or medium sized companies. The Fund may also invest in collective investment schemes. Small and medium sized companies are those whose market capitalisation is lower than that of companies in the FTSE 100 Index at the time of the Fund s investment. The Fund was established on 27 January 1981. The name of the Fund was changed to Mercury Recovery Fund (from Mercury Income and Recovery Fund) in February 1984, to Merrill Lynch Recovery Fund on 30 September 2000, to Merrill Lynch UK Value Fund on 10 September 2001 and to Merrill Lynch UK Special Situations Fund on 1 September 2004. The Fund changed its investment objective on 1 October 2006. The Fund adopted its present name with effect from 28 April 2008. Authorised Status BlackRock UK Special Situations Fund is an authorised unit trust Scheme under Section 243 of the Financial Services and Markets Act 2000 and is established as a UCITS retail Scheme under the Financial Conduct Authority s Collective Investment Schemes Sourcebook (the COLL Sourcebook ). This Interim Report covers the six months ended 31 August 2015.

The risk benchmark for the Fund is the FTSE All-Share Index. All financial investments involve an element of risk. Therefore, the value of your investment and the income from it will vary and the return of your initial investment amount cannot be guaranteed. Changes in exchange rates may cause the value of an investment to fluctuate. Past performance is not a guide to future performance and should not be the sole factor of consideration when selecting a product.

Summary of Performance over the Period The Fund returned -3.2%* over the six month period from 1 March 2015 to 31 August 2015, outperforming its benchmark, the IA UK All Companies Sector Index, which returned -3.7%. Fund Managers Commentary Though the surprisingly conclusive result in the UK s May 2015 general election provided a temporary boost to domestic stocks, the UK stock market ended the period lower due to the increasingly negative outlook for economic growth in China and fears that this will lead to a wider slowdown globally. Over the period, we recorded gains from our domestically focused small and mid-cap names, specifically Bellway and Bovis Homes, kitchen and joinery product supplier Howden Joinery and drinks maker Fever-Tree Drinks. Bovis Homes and Bellway performed well after the unexpected conservative party majority win alleviated some uncertainty over their outlook; the companies reported a record increase in the number of housing completions during the year, as well as an increase in selling prices. Clothing retailer Ted Baker continued to perform well following stronger consumer activity and positive company updates. Pharmaceutical company Clinigen saw its shares move higher after announcing that full year profits rose substantially, driven by growth in its speciality pharmaceuticals business and its recent acquisition of Idis. The biggest detractor was the holding in engineering group Senior, which fell due to concerns over aircraft production rates and foreign currency challenges. Having a holding in BG which was not quite as large as the benchmark proved detrimental, as shares of BG moved higher following discussions about a possible takeover by Royal Dutch Shell. Elsewhere, shares in plastic and fibre manufacturer Essentra fell as the slowdown in the oil & gas industry impacted its Pipe Protection business. Over the period, we purchased new positions in British American Tobacco, Rentokil and Rightmove and increased our holdings in Barclays, BHP Billiton, and Hays. We sold holdings in Diageo, Restaurant and Booker. Recent economic data from the UK and US continues to suggest a positive outlook, although the first quarter growth in both economies was lower than in previous quarters. The European Central Bank s employment of a spending programme in support of the eurozone s economy (what s become known as quantitative easing ) will be helpful in Europe, where there are now some signs of a pickup in activity. Concerns regarding Greece have subsided somewhat, but worries have now shifted to China, and investors will be closely watching how the government will respond to slower growth. We continue to focus on finding high quality, well-financed small and medium sized companies capable of prospering in today s relatively low growth world.

Notes to Financial Statements (unaudited) for the six months ended 31 August 2015 Accounting Policies The financial statements have been prepared in accordance with the Statement of Recommended Practice for Authorised Funds (the SORP ) issued by the Investment Management Association ( IMA ) (now known as the Investment Association) in May 2014. The SORP was revised in May 2014 to concur with Financial Reporting Standard 102, the new financial reporting standard applicable in the UK and Republic of Ireland. Stamp Duty Reserve Tax ( SDRT ) Prior to 30 March 2014, SDRT was levied on the dealing of units in unit trust schemes under Schedule 19 of the Finance Act 1999 ( Schedule 19 ) at the rate of 0.5% on the value of units surrendered. In order to increase the competitiveness of the asset management industry in the UK, the charge to SDRT under Schedule 19 has been abolished since 30 March 2014 and there is no SDRT charge levied on the surrender of units in unit trust schemes after this date. The transition to the revised SORP on 1 March 2015 has not resulted in any restatement to the financial position or financial performance previously reported as at 28 February 2015. Certain presentational amendments have been required which have no impact on the total return or net asset value in either the current or prior accounting period. All other accounting policies used to prepare the interim financial statements are as per the audited financial statements for the year ended 28 February 2015. Subsequent Events The Prospectus was amended on 17 September 2015 to add MarketAxess Europe Limited as an eligible market. 13 BlackRock UK Special Situations Fund 14
