Notes to Consolidated Financial Statements – (continued)
(Amounts in Millions, Except Per Share Amounts)
Share Repurchase Program
In February 2017, our Board of Directors (the "Board") authorized a new share repurchase program to repurchase from time to time up to $300.0, excluding fees, of our common stock, which was in addition to the remaining amount available to be repurchased from the $300.0 authorization made by the Board in February 2016.
We may effect such repurchases through open market purchases, trading plans established in accordance with SEC rules, derivative transactions or other means. We expect to continue to repurchase our common stock in future periods, although the timing and amount of the repurchases will depend on market conditions and other funding requirements.
The following table presents our share repurchase activity under our share repurchase programs for the three months ended March 31, 2017 and 2016.

Aggregate cost, including fees
Average price per share, including fees
As of March 31, 2017, $400.4, excluding fees, remains available for repurchase under the share repurchase programs. The share repurchase programs have no expiration date.
Redeemable Noncontrolling Interests
Many of our acquisitions include provisions under which the noncontrolling equity owners may require us to purchase additional interests in a subsidiary at their discretion. Redeemable noncontrolling interests are adjusted quarterly to their estimated redemption value, but not less than their initial fair value. Any adjustments to the redemption value impact retained earnings, except for foreign currency translation adjustments.
The following table presents changes in our redeemable noncontrolling interests.

Note 5: Income Taxes
For the three months ended March 31, 2017, our income tax benefit was driven by excess tax benefits on employee share-based payments, the majority of which is typically recognized in the first quarter due to the timing of the vesting of awards, partially offset by losses in certain foreign jurisdictions where we receive no tax benefit due to 100% valuation allowances.
We have various tax years under examination by tax authorities in various countries, and in various states, such as New York, in which we have significant business operations. It is not yet known whether these examinations will, in the aggregate, result in our paying additional taxes. We believe our tax reserves are adequate in relation to the potential for additional assessments in each of the jurisdictions in which we are subject to taxation. We regularly assess the likelihood of additional tax assessments in those jurisdictions and, if necessary, adjust our reserves as additional information or events require.
With respect to all tax years open to examination by U.S. federal, various state and local, and non-U.S. tax authorities, we currently anticipate that total unrecognized tax benefits will decrease by an amount between $25.0 and $35.0 in the next twelve months, a portion of which will affect our effective income tax rate, primarily as a result of the settlement of tax examinations and the lapsing of statutes of limitations.
