The reconciliation of the Federal statutory income tax rate to the effective income tax rate is as follows:
| Three months ended |  | Nine months ended
| September 30, 2016 |  | September 30, 2015 |  | September 30, 2016 |  | September 30, 2015
Federal statutory rate | 35.0 | % |  | 35.0 | % |  | 35.0 | % |  | 35.0 | %
State income taxes, net of Federal benefit | 4.9 |  |  | 5.8 |  |  | 5.0 |  |  | 5.5 |
Domestic manufacturing deduction | (3.0 | ) |  | (3.6 | ) |  | (3.4 | ) |  | (3.3 | )
Excess tax benefits | (2.8 | ) |  | — |  |  | (2.9 | ) |  | — |
Other | (3.0 | ) |  | (3.1 | ) |  | (1.3 | ) |  | (0.8 | )
Effective tax rate | 31.1 | % |  | 34.1 | % |  | 32.4 | % |  | 36.4 | %
As discussed in Note 11, the Company early adopted ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, applying the changes for excess tax benefits and tax deficiencies prospectively. As a result, excess tax benefits and deficiencies are reported as an income tax benefit or expense on the statement of income rather than as a component of additional paid-in capital on the statement of equity. Excess tax benefits and deficiencies are treated as discrete items to the income tax provision in the reporting period in which they occur and are noted in the above table. The Company's estimated annual 2016 effective tax rate, excluding discrete events, is approximately 36%. The Indian Employment Credit and Research and Development Credit were not extended until December 2015 for the 2015 and 2016 tax years. As such, the effective rate for the nine months ended September 30, 2016 is reduced for the impact of these credits while the effective rate for the nine months ended September 30, 2015 does not reflect these credits. Additionally, the Company had a return to provision adjustment for the three months ended September 30, 2016 of approximately $0.5 million related to a change in estimate of the Company's R&D credit. We file income tax returns in the U.S., state and foreign income tax returns jurisdictions. We are subject to U.S. examinations for tax years 2012 to present, and to non-U.S. income tax examinations for the tax years of 2011 to present. In addition, we are subject to state and local income tax examinations for the tax years 2011 to present. The Company continues to evaluate its need to file returns in various state jurisdictions. Any interest or penalties would be recognized as a component of income tax expense.
