Ivanhoe Corporation has a deferred tax asset at December $31,2022$ of $$150000$ due to the recognition of potential tax benefits of an

operating loss carryforward. The enacted tax rates are as follows: $30\%$ for $2019-2021$; $25\%$ for $2022$; and $20\%$ for $2023$ and

thereafter. Assuming that management expects that only $50\%$ of the related benefits will actually be realized, a valuation account

should be established in the amount of:

$$22500$

$$30000$

$$26250$

$$75000$
