D. Income Taxes

GBL and its greater than 80% owned operating subsidiaries file a consolidated federal income tax return. Accordingly, the income tax provision represents the aggregate of the amounts provided for all companies.

ASU 2016-09, which was issued in March 2016 and became effective for interim and annual reporting periods beginning after December 15, 2016, simplifies several aspects of accounting for employee share-based payment transactions. Upon adoption of ASU 2016-09 on January 1, 2017, our accounting for excess tax benefits has changed and adopted prospectively, resulting in recognition of excess tax benefits or tax deficiencies against income tax expenses rather than additional paid-in capital.  During the twelve months ended December 31, 2017, the ETR was higher by 0.7% as a result of a reduction to previously recorded stock compensation tax benefits.
 
The provision for income taxes for the years ended December 31, 2017, 2016 and 2015 consisted of the following:

As a result of the vesting of RSAs, and in accordance with GAAP, decreases of $0.4 million and $1.2 million were recorded in additional paid in capital for the years ended December 31, 2016 and December 31, 2015, respectively, as the actual tax benefits realized by the Company were less than the previously recorded deferred tax benefits.

As of December 31, 2017 and 2016, the total amount of gross unrecognized tax benefits related to uncertain tax positions was approximately $13.3 million and $15.0 million, respectively, of which recognition of $10.5 million and $9.8 million, respectively, would impact the Company’s effective tax rate.

As of December 31, 2017 and 2016, the net liability for unrecognized tax benefits related to uncertain tax positions was $14.5 million and $14.1 million, respectively, and is included in accrued expenses and other liabilities on the consolidated statements of financial condition.

A reconciliation of the beginning and ending amount of gross unrecognized tax benefits related to uncertain tax positions is as follows:
