The fair value of the investments held at 31 March 2026 is </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_66 tf_66\">\u00a3101,676,000 (31 March 2025: \u00a393,537,000). In the case of investments quoted on a recognised stock exchange, fair value is established by reference </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_66 tg_66\">to 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. </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_66 th_66\">In the case of unquoted investments, fair value is established in accordance with IPEV guidelines by using measurements of value such as calibrating </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_66 ti_66\">to the price of recent investment and earnings or revenue multiples; where no reliable fair value can be estimated using such techniques, unquoted </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_66 tj_66\">investments are carried at cost subject to provision for impairment where necessary. This process is used for both the valuation of unquoted equity and </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_66 tk_66\">debt investments. In the case of debt investments, debt, including both principal and any accrued interest is valued with reference to their recoverability </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_66 tl_66\">upon eventual 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 </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_66 tm_66\">price obtained remains a reasonable proxy for fair value for a period of time such that an enterprise value can be inferred and subsequently recalibrated </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_66 tn_66\">where necessary to take account of changes to either the prevailing market conditions or performance of the investee. The price of a recent investment </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_66 to_66\">is not a default position for establishing fair value as at the measurement date and when this technique is employed, the resultant valuations are cross- </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_66 tp_66\">checked 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_66 tq_66\">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_66 tr_66\">a range of comparable companies in either private or public transactions. </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_66 ts_66\">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_66 tt_66\">to the revaluation reserve.

The key assumption when using the price of a recent investment as an input to the valuation is that the </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_66 tm_66\">price obtained remains a reasonable proxy for fair value for a period of time such that an enterprise value can be inferred and subsequently recalibrated </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_66 tn_66\">where necessary to take account of changes to either the prevailing market conditions or performance of the investee. The price of a recent investment </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_66 to_66\">is not a default position for establishing fair value as at the measurement date and when this technique is employed, the resultant valuations are cross- </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_66 tp_66\">checked 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_66 tq_66\">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_66 tr_66\">a range of comparable companies in either private or public transactions. </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_66 ts_66\">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_66 tt_66\">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_66 tu_66\">statement in accordance with AIC SORP guidance. </span><span style=\"display:block;height:0px\"></span><span class=\"t s6_66 tv_66\">Investments are carried at fair value, which may reduce to nil where recoverability is considered remote.

Adjustments are made to reflect differences in scale, growth prospects, risk profile and quality of earnings. Revenue multiples are frequently </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_73 t18_73\">applied, reflecting the nature of the Company\u2019s portfolio which predominantly comprises growth-oriented and technology businesses that are not </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_73 t19_73\">typically profitable in the earlier stages of development. Once an investee company reaches sufficient scale and sustained profitability, valuation </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_73 t1a_73\">approaches are more commonly based on EBITDA or earnings multiples. </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_73 t1b_73\">In applying comparable trading multiples to the valuation of equity instruments, the Company identifies appropriate sector valuation reports. These </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_73 t1c_73\">multiples are then adjusted to reflect factors such as illiquidity, marketability and other company-specific differences between the portfolio company and </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_73 t1d_73\">the selected public comparators. </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_73 t1e_73\">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_73 t1f_73\">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_73 t1g_73\">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_73 t1h_73\">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_73 t1i_73\">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_73 t1j_73\">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_74 tb_74\">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_74 tc_74\">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_74 td_74\">FRS 102 requires consideration of the sensitivity of fair value measurements to reasonably possible alternative assumptions.

Adjustments are made to reflect differences in scale, growth prospects, risk profile and quality of earnings. Revenue multiples are frequently </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_73 t18_73\">applied, reflecting the nature of the Company\u2019s portfolio which predominantly comprises growth-oriented and technology businesses that are not </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_73 t19_73\">typically profitable in the earlier stages of development. Once an investee company reaches sufficient scale and sustained profitability, valuation </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_73 t1a_73\">approaches are more commonly based on EBITDA or earnings multiples. </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_73 t1b_73\">In applying comparable trading multiples to the valuation of equity instruments, the Company identifies appropriate sector valuation reports. These </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_73 t1c_73\">multiples are then adjusted to reflect factors such as illiquidity, marketability and other company-specific differences between the portfolio company and </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_73 t1d_73\">the selected public comparators. </span><span style=\"display:block;height:0px\"></span><span class=\"t s5_73 t1e_73\">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_73 t1f_73\">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_73 t1g_73\">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_73 t1h_73\">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_73 t1i_73\">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_73 t1j_73\">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_74 tb_74\">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_74 tc_74\">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_74 td_74\">FRS 102 requires consideration of the sensitivity of fair value measurements to reasonably possible alternative assumptions.
