Income Tax Disclosure [Abstract]  
INCOME TAXES INCOME TAXES
The Company recorded an income tax expense of $3.5 million for the three months ended December 31, 2020, resulting in an effective tax rate of 10.77%, compared to an income tax benefit of $0.7 million, or an effective tax rate of 2.97%, for the three months ended December 31, 2019. The Company’s effective tax rate was lower than the U.S. statutory rate of 21% primarily because of the anticipated effect of investment tax credits during fiscal year 2019. The Company’s effective tax rate in the future will depend in part on actual investment tax credits earned as part of its financing of solar energy projects.

The table below compares the income tax expense components for the periods presented.
