As of December 31, 2016, we have $2.56 billion of remaining share repurchase authorizations from our board of directors. We may utilize various methods to effect the repurchases, which could include open market repurchases, negotiated block transactions, accelerated share repurchases or open market solicitations for shares, some of which may be affected through Rule 10b5-1 plans. The timing and amount of future repurchases, if any, will depend upon several factors, including market and business conditions, and such repurchases may be discontinued at any time.

Total share repurchases were as follows for the respective periods:

(In millions, except per share data)	2016		2015		2014
Number of shares repurchased	4		19		49
Cash paid for shares repurchased	$	197	$	965	$	2,131
Effective average cost per delivered share	$	41.84	$	50.31	$	44.31
