问题如下：

Lily is an expert in analyzing manufactoring industry. She finds that Firm C has a history of continous losses and a large amount of inventories whose book value is much higher than market value. As Firm C also has a very large deferred tax asset, Lily says, " I will do nothing to reduce the deferred tax asset. As the difference between taxable and pretax income is temporary, the deferred tax asset will be smaller in the future." Is her statement correct?

选项：

A.

Incorrect. She should record a deferred tax liability to offset the temporary difference.

B.

Incorrect. She should recognize a valuation allowance.

C.

Correct.

解释：

B is correct.

It is difficult for Firm C to generate profit from inventory. Based on its history, Firm C probabily suffer the losses in the future. Thus, its deferred tax assets is unlikely to be realized and should be offset by a valuation allowance.

考点：当DTA长期无法转会时的处理

C公司有持续亏损的历史和大量账面价值远高于市场价值的存货。推断出C公司很难从存货中产生利润。基于其历史，C公司很可能在未来继续亏损。因此，C公司B/S上用于后续抵税的递延所得税资产(DTA)不太可能使用，因此需要计提valuation allowance，递减部分DTA，可以理解为DTA减值了。
