Income Taxes

The Company’s tax provision for interim periods is determined using an estimated annual effective tax rate, adjusted for discrete items arising in that quarter. In each quarter, the estimated annual effective tax rate is updated and a year to date adjustment is made to the provision. The Company’s quarterly effective tax rate is subject to significant change due to the effect of discrete items arising in a given quarter.

Income tax expense for the quarter ended March 31, 2020, was $3,224, for an effective tax rate of 24.7 percent. The effective tax rate differed from the 21 percent federal statutory rate on pretax income, primarily due to state taxes, estimated increase in the Company's valuation allowance related to state income tax attributes, and the discrete tax impact of vested share-based awards, partially offset by federal and state credits, and the deduction applicable to income derived from export activity.

On March 11, 2020, the World Health Organization classified the novel strain of coronavirus ("COVID-19") a global pandemic. In response to COVID-19, President Donald Trump signed into law the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) on March 27, 2020. The CARES Act along with other guidance issued by the IRS provides for numerous tax provisions and other stimulus measures, including temporary suspension of certain payment requirements for the employer portion of Social Security taxes, deferral of income tax payments until July 15, 2020 and technical corrections from prior tax legislation. The Company anticipates it may potentially benefit from provisions within the CARES Act and other technical guidance. MGP is reviewing the provisions and where certain tax provisions of the CARES Act and other related guidance are determined to be applicable to the Company, the tax impact and other related benefits will be recorded in the Company’s

financial statements in the period in which the legislation was enacted or the benefit incurred.There was an income tax benefit for the quarter ended March 31, 2019, of $1,459, for an effective tax rate of (17.7) percent. The effective tax rate differed from the 21 percent federal statutory rate on pretax income, primarily due to the tax impact of vested share-based awards, the tax impact of state and federal tax credits, partially offset by state taxes and certain compensation being subject to the compensation deduction limitations applicable for public companies.
