某企业将某项资产与国外企业合资,要求对资产进行评估。具体资料如下:该资产账面原值为270万元,净值为108万元,按财务制度规定该资产的折旧年限为30年,已计提折旧年限为20年。经调查分析确定,按现在的市场材料价格和工资费用水平,新建造相同构造的资产的全部费用支出为480万元。经查询原始资料和企业记录,该资产截止到评估基准日的法定利用时间为57600小时,实际累计利用时间为50400小时。经专业人员勘察估算,该资产还能使用8年。又知该资产由于设计不合理,造成耗电量大、维修费用高,与现在同类标准资产比较,每年多支出营运成本3万元(该企业适用的所得税税率为25%,假定折现率为10%)。要求:根据上述资料,采用成本法对该资产进行评估。
