18. Accumulated Other Comprehensive Income

Components of comprehensive income (loss) are net income (loss) and all changes in equity during a period except those resulting from transactions with owners. Our accumulated other comprehensive income (loss) consists of changes in the fair value of derivative instruments, net of tax, that are designated as cash flow hedges, amortization of terminated interest rate swaps and adjustments related to changes in our ownership of the Partnership.

The following table presents the changes in accumulated other comprehensive income (loss) of our derivative cash flow hedges, net of tax and excluding noncontrolling interest, during the three and nine months ended September 30, 2018 and 2017 (in thousands):
