Income Taxes	8. Income Taxes Our effective income tax rate increased to 70.2% for the first quarter of 2017 from 63.7% for the first quarter of 2016. Our effective income tax rate for the first quarter of 2017 is higher than the United States (“U.S”) statutory rate as well as the effective income tax rate for the first quarter of 2016 primarily as a result of $2.2 million of tax deficiencies related to the vesting of stock-based awards recorded in the first quarter of 2017 resulting from the adoption of new accounting guidance related to stock-based compensation. See Note 11 for additional information. Additionally, we are currently undergoing several federal, foreign and state audits, however, we currently do not believe these audits will result in any material charge to tax expense in the future.
