The fair </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_64 t17_64\">value of the unlisted investments at the balance sheet date was \u00a393,507,000. </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_64 t18_64\">The key judgement in the valuation of the unquoted investments process is the Directors\u2019 determination of the appropriate application of the International </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_64 t19_64\">Private Equity and Venture Capital (\u2018IPEV\u2019) guidelines to each unlisted investment. The judgement applied in the selection of the methodology used for </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_64 t1a_64\">determining the fair value of each unlisted investment can have a significant impact upon the valuation.</span><span style=\"display:block;height:0px\"></span>\n      \n    \n      \n        \n          \n            <span class=\"t s5_65 tb_65\">(c) Valuation of investments </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_65 tc_65\">Purchases and sales of investments are recognised in the financial statements at the date of transaction (trade date). </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_65 td_65\">As permitted by FRS 102 chapters 11 and 12, the Company\u2019s investments are recorded at fair value at the point of acquisition and are measured at </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_65 te_65\">subsequent reporting dates at fair value, with any changes being recognised in profit or loss. The fair value of the investments held at 31 March 2026 is </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_65 tf_65\">\u00a398,447,000 (31 March 2025: \u00a387,889,000). In the case of investments quoted on a recognised stock exchange, fair value is established by reference to </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_65 tg_65\">the closing bid price on the relevant date or the last traded price, depending on the convention of the exchange on which the investment is quoted. In the </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_65 th_65\">case of unquoted investments, fair value is established in accordance with IPEV guidelines by using measurements of value such as calibrating to the price </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_65 ti_65\">of recent investment and earnings or revenue multiples; where no reliable fair value can be estimated using such techniques, unquoted investments are </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_65 tj_65\">carried at cost subject to provision for impairment where necessary. This process is used for both the valuation of unquoted equity and debt investments. </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_65 tk_65\">In the case of debt investments, debt, including both principal and any accrued interest is valued with reference to their recoverability upon eventual </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_65 tl_65\">sale of the Company\u2019s investment. The key assumption when using the price of a recent investment as an input to the valuation is that the price obtained </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_65 tm_65\">remains a reasonable proxy for fair value for a period of time such that an enterprise value can be inferred and subsequently recalibrated where </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_65 tn_65\">necessary to take account of changes to either the prevailing market conditions or performance of the investee. The price of a recent investment is not a </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_65 to_65\">default position for establishing fair value as at the measurement date and when this technique is employed, the resultant valuations are cross-checked </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_65 tp_65\">for reasonableness by employing an alternative valuation technique. The key assumptions for the multiples approach are the selection of the most </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_65 tq_65\">appropriate earnings or revenue measure (historic or forecast) and the selection of the multiple itself which may be influenced by the multiples achieved by </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_65 tr_65\">a range of comparable companies in either private or public transactions. </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_65 ts_65\">Gains and losses arising from changes in fair value of investments are recognised as part of the capital return within the income statement and allocated </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_65 tt_65\">to the revaluation reserve. Transaction costs attributable to the acquisition or disposal of investments are charged to capital return within the income </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_65 tu_65\">statement in accordance with AIC SORP guidance. </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_65 tv_65\">Investments are carried at fair value, which may reduce to nil where recoverability is considered remote.

Valuations are calculated by reference to the most recent financial performance of the portfolio company </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_72 t17_72\">and the relevant multiples observed for comparable companies. Adjustments are made to reflect differences in scale, growth prospects, risk profile and </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_72 t18_72\">quality of earnings. Revenue multiples are frequently applied, reflecting the nature of the Company\u2019s portfolio which predominantly comprises growth- </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_72 t19_72\">oriented and technology businesses that are not typically profitable in the earlier stages of development. Once an investee company reaches sufficient </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_72 t1a_72\">scale and sustained profitability, valuation approaches are more commonly based on EBITDA or earnings multiples. </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_72 t1b_72\">In applying comparable trading multiples to the valuation of equity instruments, the Company uses appropriate sector valuation reports. These multiples </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_72 t1c_72\">are then adjusted to reflect factors such as illiquidity, marketability and other company-specific differences between the portfolio company and the </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_72 t1d_72\">selected public comparators. </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_72 t1e_72\">Where valuations are based on cost or the price of a recent investment, the Company undertakes a calibration process at each valuation date. This </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_72 t1f_72\">involves assessing the performance and progress of the investee relative to the original investment case, considering whether any key events or milestones </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_72 t1g_72\">have occurred that may indicate a change in value, and determining whether an alternative approach, such as a market-based multiple or discounted </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_72 t1h_72\">cash flow methodology, would be more appropriate. Consideration is also given to the circumstances surrounding the transaction where the investment </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_72 t1i_72\">price may not represent fair value, for example where there has been disproportionate dilution of existing shareholders or where market conditions at the </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_72 t1j_72\">time of investment no longer reflect those at the valuation date.</span><span style=\"display:block;height:0px\"></span>\n      \n    \n      \n        <span class=\"t s5_73 tb_73\">The Directors consider that, for each investment, the valuation methodology selected represents the most appropriate approach having regard to the </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_73 tc_73\">nature and performance of the business, market conditions and the IPEV guidelines, and provides a reliable estimate of fair value as at 31 March 2026. </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_73 td_73\">FRS 102 requires consideration of the sensitivity of fair value measurements to reasonably possible alternative assumptions.

Valuations are calculated by reference to the most recent financial performance of the portfolio company </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_72 t17_72\">and the relevant multiples observed for comparable companies. Adjustments are made to reflect differences in scale, growth prospects, risk profile and </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_72 t18_72\">quality of earnings. Revenue multiples are frequently applied, reflecting the nature of the Company\u2019s portfolio which predominantly comprises growth- </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_72 t19_72\">oriented and technology businesses that are not typically profitable in the earlier stages of development. Once an investee company reaches sufficient </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_72 t1a_72\">scale and sustained profitability, valuation approaches are more commonly based on EBITDA or earnings multiples. </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_72 t1b_72\">In applying comparable trading multiples to the valuation of equity instruments, the Company uses appropriate sector valuation reports. These multiples </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_72 t1c_72\">are then adjusted to reflect factors such as illiquidity, marketability and other company-specific differences between the portfolio company and the </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_72 t1d_72\">selected public comparators. </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_72 t1e_72\">Where valuations are based on cost or the price of a recent investment, the Company undertakes a calibration process at each valuation date. This </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_72 t1f_72\">involves assessing the performance and progress of the investee relative to the original investment case, considering whether any key events or milestones </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_72 t1g_72\">have occurred that may indicate a change in value, and determining whether an alternative approach, such as a market-based multiple or discounted </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_72 t1h_72\">cash flow methodology, would be more appropriate. Consideration is also given to the circumstances surrounding the transaction where the investment </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_72 t1i_72\">price may not represent fair value, for example where there has been disproportionate dilution of existing shareholders or where market conditions at the </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_72 t1j_72\">time of investment no longer reflect those at the valuation date.</span><span style=\"display:block;height:0px\"></span>\n      \n        <span class=\"t s5_73 tb_73\">The Directors consider that, for each investment, the valuation methodology selected represents the most appropriate approach having regard to the </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_73 tc_73\">nature and performance of the business, market conditions and the IPEV guidelines, and provides a reliable estimate of fair value as at 31 March 2026. </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_73 td_73\">FRS 102 requires consideration of the sensitivity of fair value measurements to reasonably possible alternative assumptions.
