Income Taxes	9 Months Ended
Nov. 30, 2017
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We had $30.8 million of gross unrecognized tax benefits as of November 30, 2017, and $30.0 million as of February 28, 2017. There were no significant changes to the gross unrecognized tax benefits as reported for the year ended February 28, 2017, as all activity was related to positions taken on tax returns previously filed or intended to be filed in the current fiscal year. Subsequent to November 30, 2017, Congress passed and the President signed the Tax Cuts and Jobs Act of 2017 into law, effective January 1, 2018. While we are still evaluating the full impact of the legislation, we expect the substantial reduction of the federal corporate tax rate, from 35% to 21%, to benefit our financial results and cash flow in future periods. Our fourth quarter effective income tax rate will reflect the benefit of the pro-rata two-month tax rate reduction for fiscal 2018. This benefit will partially offset a one-time unfavorable impact to tax expense of an estimated $50 million to $65 million related to the revaluation of our deferred tax asset incorporating the new federal tax rate. The actual amounts recognized will be impacted by our analysis of the law and our fourth quarter financial results.
