In 2018, the Company received information from the IRS regarding certain aspects of the its adopted accounting method used to calculate qualifying tangible property repair cost deductions and increased its reserve provision to $4.1 million.

The modifications also impacted the Company’s filed 2015, 2016 and 2017 federal income tax returns. The Company paid $0.8 million in income taxes in connection with the conclusion of the 2014 and 2015 tax years. The IRS is currently examining the 2016 and 2017 tax years to determine the impact of the modifications on those tax years. The Company reduced its income tax reserve provision to $3.1 million as of March 31, 2019. Pending completion of the 2016 and 2017 examinations, the final tax liability could be different than the recorded reserve provision. For the three months ended March 31, 2019, the Company reduced its potential interest expense liability to $0.3 million as a result of the closing of the 2014 and 2015 tax years and the revised income tax reserve provision.
