The effective tax rates for the Company was (2.6)% and 137.7% for the three months ended September 30, 2019 and September 30, 2018, respectively.

The effective tax rates for the Company of 1.2% and (17.2)% for the nine months ended September 30, 2019 and September 30, 2018, respectively.

This difference is primarily due to the full valuation allowance recorded during this period in 2019. There was no valuation allowance recorded in the same period of 2018 and the effective tax rate reflects certain discrete tax items. In addition, the Company recorded significant permanent differences in 2018 related to stock-based compensation.
