Annual Report 2008 年報 123 17. 商譽減值測試（續） 舜宇恒平儀器 此單位可收回金額按使用價值計算方法來釐 定。此方法使用現金流量預測的方法，該預 測是基於管理層批准之五年期財務預測，並 且折扣率為 21.53% （二零零七年： 7.83 ％）。 舜宇恒平儀器的現金流量在五年期後以零增 長率推算。這一增長率是根據管理層最佳預 測及舜宇恒平過往的增長趨勢為依據。按照 使用價值計算的其他關鍵假設涉及到含括銷 售預算和毛利率預算的現金流入 ╱ 出預估， 該預估是根據該單位的過去的業績和管理層 對市場的發展預期來釐定的。管理層認為， 這些假設中可能發生的任何合理變化，不會 造成舜宇恒平儀器的賬面價值總額的超過舜 宇恒平儀器合計的可收回的總金額。 力量光學 此單位可收回金額按使用價值計算方法來釐 定。此方法使用現金流量預測的方法，該預 測是基於管理層批准之五年期財務預測，並 且折扣率為 19% 。力量光學的現金流量在五 年期後以 2.5% 持續增長率推算。這一增長率 是根據力量光學及相關行業過往數年的增長 趨勢為依據。按照使用價值計算的其他關鍵 假設涉及到含括銷售預算和毛利率預算的現 金流入 ╱ 出預估，該預估是根據該單位的過 去的業績和管理層對市場的發展預期而釐定 的。管理層認為，這些假設可能可能發生的 合理變化，不會造成力量光學的賬面價值總 額的超過力量光學合計的可收回的總金額。 17.IMPAIRMENT TESTING ON GOODWILL (Continued) Sunny Hengping The recoverable amount of this unit has been determined based on a value in use calculation. That calculation uses cash flow projections based on financial budgets approved by management covering a five-year period, and discount rate of 21.53% (2007: 7.83%). Sunny Hengping’s cash flows beyond the five-year period are extrapolated using a zero growth rate. This growth rate is based on the management’s best estimation and past few years growth trend of Sunny Hengping. Other key assumptions for the value in use calculations relate to the estimation of cash inflows/outflows which include budgeted sales and gross margin, such estimation is based on the unit’s past performance and management’s expectations for the market development. Management believes that any reasonably possible change in any of these assumptions would not cause the aggregate carrying amount of Sunny Hengping to exceed the aggregate recoverable amount of Sunny Hengping. Power Optics The recoverable amount of this unit has been determined based on a value in use calculation. That calculation uses cash flow projections based on financial budgets approved by management covering a five-year period, and discount rate of 19%. Power Optics’ cash flows beyond the five-year period are extrapolated using a steady 2.5% growth rate. This growth rate is based on the past few years growth trend of Power Optics and relevant industry. Other key assumptions for the value in use calculations relate to the estimation of cash inflows/outflows which include budgeted sales and gross margin, such estimation is based on the unit’s past performance and management’s expectations for the market development. Management believes that any reasonably possible change in any of these assumptions would not cause the aggregate carrying amount of Power Optics to exceed the aggregate recoverable amount of Power Optics.
