Book value is the unamortized cost of the asset which still appears on the accounting books of the business. 帐面价值是依旧保留在企业帐册中的未摊提的资本成本。
If the use of the trademark is discontinued or its contribution to earnings becomes doubtful, any unamortized cost should be written off immediately. 如果商标停止使用或它对增加收益的作用令人置疑,所有未摊销的成本应被立即冲销。
