Uncertain Tax Positions The following is a reconciliation of the Company's beginning and ending amount of uncertain tax positions (in millions):
## Table 0 ##
The Company's liability for uncertain tax positions as of December 31, 2015, 2014, and 2013, includes $180 million, $154 million, and $141 million, respectively, related to amounts that would impact the effective tax rate if recognized.
It is possible that the amount of unrecognized tax benefits may change in the next twelve months; however, we do not expect the change to have a significant impact on our consolidated statements of income or consolidated balance sheets.
These changes may be the result of settlements of ongoing audits.
At this time, an estimate of the range of the reasonably possible outcomes within the twelve months cannot be made.
The Company recognizes interest and penalties related to uncertain tax positions in its provision for income taxes.
The Company accrued potential interest and penalties of $2 million, $4 million, and $2 million in 2015, 2014, and 2013, respectively.
The Company recorded a liability for interest and penalties of $33 million, $31 million, and $27 million as of December 31, 2015, 2014, and 2013, respectively.
The Company and its subsidiaries file income tax returns in their respective jurisdictions.
The Company has substantially concluded all U. S.  federal income tax matters for years through 2007.
Material U. S.  state and local income tax jurisdiction examinations have been concluded for years through 2005.
The Company has concluded income tax examinations in its primary non-U.
S.  jurisdictions through 2005.9.
Shareholders' Equity Distributable Reserves As a U. K.  incorporated company, the Company is required under U. K.  law to have available "distributable reserves" to make share repurchases or pay dividends to shareholders.
Distributable reserves may be created through the earnings of the U. K.  parent company and, amongst other methods, through a reduction in share capital approved by the English Companies Court.
Distributable reserves are not linked to a U. S.  GAAP reported amount (e. g. , retained earnings).
As of December 31, 2015 and 2014, the Company had distributable reserves in excess of $2.1 billion and $4.0 billion, respectively.
Ordinary Shares In April 2012, the Company's Board of Directors authorized a share repurchase program under which up to $5.0 billion of Class A Ordinary Shares may be repurchased ("2012 Share Repurchase Program").
In November 2014, the Company's Board of Directors authorized a new $5.0 billion share repurchase program in addition to the existing program ("2014 Share Repurchase Program" and, together, the "Repurchase Programs").
Under each program, shares may be repurchased through the open market or in privately negotiated transactions, based on prevailing market conditions, funded from available capital.
During 2015, the Company repurchased 16.0 million shares at an average price per share of $97.04 for a total cost of $1.6 billion under the Repurchase Programs.
During 2014, the Company repurchased 25.8 million shares at an average price per share of $87.18 for a total cost of $2.3 billion under the 2012 Share Repurchase Plan.
In August 2015, the $5 billion of Class A Ordinary Shares authorized under the 2012 Share Repurchase Program was exhausted.
At December 31, 2015, the remaining authorized amount for share repurchase under the 2014 Share Repurchase Program is $4.1 billion.
Under the Repurchase Programs, the Company repurchased a total of 78.1 million shares for an aggregate cost of $5.9 billion.

Our operations are currently organized into two reportable segments, Refining and HEP.
The Refining segment includes the operations of our El Dorado, Tulsa, Navajo, Cheyenne and Woods Cross Refineries and NK Asphalt.
The HEPsegment involves all of the operations of HEP effective March 1, 2008 (date of reconsolidation).

REFINERY OPERATIONS Our refinery operations serve the Mid-Continent, Southwest and Rocky Mountain regions of the United States.
We own and operate five complex refineries having an aggregate crude capacity of 443,000 barrels per stream day.
Each of our refineries has the complexity to convert discounted, heavy and sour crude oils into a high percentage of gasoline, diesel and other high-value refined products.
For 2012, gasoline, diesel fuel, jet fuel and specialty lubricants (excluding volumes purchased for resale) represented 50%, 31%, 6% and 3%, respectively, of our total refinery sales volumes.
The tables presented below and elsewhere in this discussion of our refinery operations set forth information, including non-GAAP performance measures, about our refinery operations.
The cost of products and refinery gross and net operating margins do not include the effect of depreciation and amortization.
Reconciliations to amounts reported under GAAP are provided under “Reconciliations to Amounts Reported Under Generally Accepted Accounting Principles” following Item 7A of Part II of this Form 10-K.
