Cash Flows Changes in cash and cash equivalents were as follows (in millions).
## Table 0 ##
Changes in cash and cash equivalents include amounts related to discontinued operations.
Operating Activities Cash provided by operating activities increased $432 million for the year ended December 31, 2011 as compared to the year ended December 31, 2010.
The increase in cash provided by operating activities was driven by increased operating results, a decrease in taxes paid, a decrease in interest payments, and decreases in stock compensation payments for cash settled equity awards.
During 2010, there was a $112 million overpayment of tax (“2010 overpayment”) resulting primarily from an extension of the tax law in the fourth quarter of 2010 that allowed for the immediate deduction of certain domestic programming costs.
During 2011, we received a $39 million tax refund related to the 2010 overpayment and there was a decrease in tax payments of $107 million primarily attributable to the use of the remaining overpayment carry forward from 2010.
The decrease in interest payments was principally the result of $114 million of makewhole premiums paid in 2010 in connection with the refinancing of most of our outstanding debt.
The $32 million decrease in payments for cash-settled equity awards was attributable to the decrease in number of outstanding unit awards and SARs.
These improvements were partially offset by a $110 million increase in cash used by operating activities attributable to investments in programming.
Cash provided by operating activities for the year ended December 31, 2010 increased by $26 million as compared to the year ended December 31, 2009.
The increase in cash provided by operating activities was driven by increased earnings, principally from increased advertising and distribution revenues at our U. S.  Networks and International Networks segments, and a decrease of $49 million in tax payments, principally due to a nonrecurring tax payment in 2009 related to the gain on the U. S.  Discovery Kids Transaction.
These increases were partially offset by $114 million of make-whole premiums paid in connection with refinancing most of our outstanding debt in June 2010 and a $77 million increase in payments for cash-settled equity awards.
The increase in payments for cash-settled equity awards was attributable to the increase in fair value of outstanding awards due to the increase in the prices of our Series A common stock and settlements of SARs granted in late 2008 and early 2009 as part of a transition from an existing equity plan under which we typically granted cash-settled awards to a new equity plan under which we typically issue stock-settled awards.
Investing Activities Cash flows used in investing activities increased $24 million for the year ended December 31, 2011 as compared to the year ended December 31, 2010.
The increase was attributable to a $24 million increase in funding to unconsolidated equity method investees and a $9 million increase in payments for purchases of property and equipment.
The increase in funding to unconsolidated equity method investees was primarily due to continued investments in OWN, which was launched on January 1, 2011.
The increase in cash used in investing activities in 2011 was partially offset by a $12 million decrease in cash used in business acquisitions, net of cash acquired.
During 2011 we used $26 million for the acquisition of a factual entertainment production company in the U. K.  and a Latin American cable channel.
Cash flows used in investing activities for the year ended December 31, 2010 included $35 million for the acquisition of an uplink facility.
Cash used in investing activities for the year ended December 31, 2010 was $190 million as compared to cash provided by investing activities of $238 million for the year ended December 31, 2009.
The decline in cash flows from investing activities was due to a decline in cash from business and investment dispositions, an increase in cash used for business acquisitions, and increased funding payments to unconsolidated ventures, which were partially offset by a reduction in capital expenditures.
Cash used in investing activities during 2010 consisted of $127 million in funding to our unconsolidated network ventures, payments of $49 million for property and equipment acquisitions and $35 million for the purchase of an uplink facility, which were partially offset by net proceeds of $24 million related to the sale of our Antenna Audio business.
(b) As of December 31, 2014, the total amount authorized under the stock repurchase program was $5.5 billion and we had remaining authorization of $738 million for future repurchases under our common stock repurchase program, which will expire on February 3, 2016.
Under the stock repurchase program, management is authorized to purchase shares of the Company's common stock from time to time through open market purchases or privately negotiated transactions at prevailing prices as permitted by securities laws and other legal requirements, and subject to stock price, business and market conditions and other factors.
We have been funding and expect to continue to fund stock repurchases through a combination of cash on hand and cash generated by operations.
In the future, we may also choose to fund our stock repurchase program under our revolving credit facility or future financing transactions.
There were no repurchases of our Series A and B common stock during the three months ended December 31, 2014.
The Company first announced its stock repurchase program on August 3, 2010.
