Power Integrations  (STU:PWI) Tax Expense Explanation

In the long run, income before tax and taxable income will likely be more similar than they are in any given period. If the one is less in earlier years, then it will be greater in later years. Deferred taxes will reverse themselves in the long run and in total will zero out, unless there is something like a change in tax rates in the intervening period. A deferred tax payable results from a tax break in the early years and will reverse itself in later years; a deferred tax receivable results from more taxes being paid in early years than the tax expense reported to shareholders and will again reverse itself in later years. The deferred tax amount is computed by estimating the amount and the timing of the reversal and multiplying that by the appropriate tax rates.
