Income Tax Disclosure [Abstract]
Income Taxes	Note 11. Income Taxes On December 22, 2017, the President signed into legislation The Tax Cuts and Jobs Act (the Act). The Act changes existing U.S. tax law and includes numerous provisions that will affect our business, including our income tax accounting, disclosure and tax compliance. We believe the most impactful changes within the Act are those that will reduce the U.S. corporate tax rates, business-related exclusions and deductions and credits. ASC 740, “Income Taxes” (Topic 740), requires the effects of changes in tax rates and laws on deferred tax balances to be recognized in the period in which the legislation is enacted. Consequently, as of the date of enactment, and during the three months ended February 28, 2018, Greystone will value all deferred tax assets and liabilities at the newly enacted Corporate U.S. income tax rate. Greystone is currently evaluating the impact of the Act, which will include revaluing the deferred tax assets and liabilities and will disclose the estimated impact upon recognition in the third quarter of fiscal 2018.
