Debt

During the three months ended March 31, 2018, we made principal payments of $15.0 million on our senior secured non-recourse notes issued by Northwind Holdings, LLC.

At March 31, 2018, letters of credit totaling $2.1 million had been issued from the credit facility, but there were no borrowed amounts outstanding.

Income Tax Disclosure

Income Tax

On December 22, 2017, the U.S. Federal government enacted the TCJA, which reduces the federal corporate tax rate from 35 percent to 21 percent effective January 1, 2018.  We are applying the guidance in Staff Accounting Bulletin (SAB) 118 when accounting for the enactment-date effects of TCJA.  At March 31, 2018, our estimates recorded at December 31, 2017 for the tax effects of TCJA are not final. We will continue to refine our calculations as additional analysis is completed and record the final amounts during the one year measurement period after the enactment date as allowed by SAB 118. Tax rate estimates recorded at December 31, 2017 and March 31, 2018 may be impacted by changes in accounting and tax interpretations of the TCJA legislation.
