Note 8 - Income Taxes

Effective Tax Rate

The Company’s effective tax rate from continuing operations for the first quarter of fiscal 2021 was an expense on pre-tax income of 27.5%, compared to a benefit on a pre-tax loss of 27.8% for the prior year period. For each quarterly period, the Company’s effective tax rate from continuing operations was higher than the U.S. federal statutory rate of 21% primarily due to the aggregate impact of state taxes and the impact of permanent differences from non-deductible expenses on the projected annual effective tax rate applied to the quarterly results.

Valuation Allowances

The Company assesses the realizability of its deferred tax assets on a quarterly basis through an analysis of potential sources of future taxable income, including prior year taxable income available to absorb a carryback of tax losses, reversals of existing taxable temporary differences, tax planning strategies, and forecasts of taxable income. The Company considers all negative and positive evidence, including the weight of the evidence, to determine if valuation allowances against deferred tax assets are required. The Company maintains valuation allowances against certain state, Canadian and all Puerto Rican deferred tax assets.

The Company files federal and state income tax returns in the U.S. and foreign tax returns in Puerto Rico and Canada. For U.S. federal income tax returns, fiscal years 2013 to 2020 remain subject to examination under the statute of limitations.
