only those CPU and AMD APU products that are commonly referred to as “processors in a box” and for certain server CPU products.
The Company also offered extended limited warranties to certain customers of “tray” microprocessor products and/or professional graphics products who have written agreements with the Company and target their computer systems at the commercial and/or embedded markets.
Changes in the Company’s estimated liability for product warranty during the years ended December 26, 2015 and December 27, 2014 are as follows:
## Table 0 ##
In addition to product warranties, the Company, from time to time in its normal course of business, indemnifies other parties, with whom it enters into contractual relationships, including customers, lessors and parties to other transactions with the Company, with respect to certain matters.
In these limited matters, the Company has agreed to hold certain third parties harmless against specific types of claims or losses, such as those arising from a breach of representations or covenants, third-party claims that the Company’s products when used for their intended purpose(s) and under specific conditions infringe the intellectual property rights of a third party, or other specified claims made against the indemnified party.
It is not possible to determine the maximum potential amount of liability under these indemnification obligations due to the unique facts and circumstances that are likely to be involved in each particular claim and indemnification provision.
Historically, payments made by the Company under these obligations have not been material.
NOTE 16: Contingencies Securities Class Action On January 15, 2014, a class action lawsuit captioned Hatamian v.  AMD, et al.
, C. A.
No.3:14-cv-00226 (the “Hatamian Lawsuit”) was filed against the Company in the United States District Court for the Northern District of California.
The complaint purports to assert claims against the Company and certain individual officers for alleged violations of Section 10(b) of the Securities Exchange Act of 1934, as amended (the Exchange Act), and Rule 10b-5 of the Exchange Act.
The plaintiffs seek to represent a proposed class of all persons who purchased or otherwise acquired our common stock during the period April 4, 2011 through October 18, 2012.
The complaint seeks damages allegedly caused by alleged materially misleading statements and/or material omissions by the Company and the individual officers regarding its 32nm technology and “Llano” product, which statements and omissions, the plaintiffs claim, allegedly operated to artificially inflate the price paid for the Company’s common stock during the period.
The complaint seeks unspecified compensatory damages, attorneys’ fees and costs.
On July 7, 2014, the Company filed a motion to dismiss plaintiffs’ claims.
On March 31, 2015, the Court denied the motion to dismiss.
On May 14, 2015, the Company filed its answer to plaintiffs’ corrected amended complaint.
The discovery process is ongoing.
On September 4, 2015, plaintiffs filed their motion for class certification.
A court-ordered mediation held in January 2016 did not result in a settlement of the lawsuit.
Based upon information presently known to management, the Company believes that the potential liability, if any, will not have a material adverse effect on its financial condition, cash flows or results of operations.
ITEM 6.
SELECTED FINANCIAL DATA Five Years Ended December 26, 2015 (In millions except per share amounts)
## Table 1 ##
(1) 2015, 2014, 2013 and 2012 consisted of 52 weeks, whereas 2011 consisted of 53 weeks.
(2) In 2013, we entered into licenses and settlements regarding patent-related matters.
Pursuant to these licenses and settlements, we received in aggregate, $48 million, net, which we recorded within net legal settlements in 2013.
(3) During 2011, we changed the method of accounting for our investment in GF from the equity method to the cost method of accounting.
As a result of the change, we recognized a non-cash gain of approximately $492 million, net of certain transaction related charges.
In 2011, we recorded a non-cash impairment charge of approximately $209 million related to our investment in GF.
(4) During the first quarter of 2012, we entered into a second amendment to the WSA with GF.
The primary effect of this amendment was to modify certain pricing and other terms of the WSA applicable to wafers for our microprocessor and APU products, to be delivered by GF to us during 2012.
As a result of the amendment, we recorded a $703 million charge during the first quarter of 2012.
During the fourth quarter of 2012, we entered into a third amendment to the WSA.
Pursuant to the third amendment, we modified our wafer purchase commitments for the fourth quarter of 2012 made pursuant to the second amendment to the WSA.
In addition, we agreed to certain pricing and other terms of the WSA applicable to wafers for our microprocessor and APU products, to be delivered by GF to us from the fourth quarter of 2012 through December 31, 2013.
Pursuant to the third amendment, GF agreed to waive a portion of our production wafer purchase commitments for the fourth quarter of 2012.
In consideration for this waiver, we agreed to pay GF a fee of $320 million, which resulted in a $273 million lower of cost or market charge recorded in the fourth quarter of 2012.
(5) In 2015, 2014, 2012 and 2011, we implemented restructuring plans and incurred net charges of $53 million, $58 million, $6 million, $100 million and $100 million in 2015, 2014, 2013, 2012 and 2011, respectively, which primarily consisted of severance and related employee benefits.
Purchases of Equity Securities The following table provides information about our repurchases of our common stock registered pursuant to Section 12 of the Exchange Act during the quarter ended December 31, 2016.
## Table 2 ##
(a) We close our books and records on the last Sunday of each month to align our financial closing with our business processes, except for the month of December, as our fiscal year ends on December 31.
As a result, our fiscal months often differ from the calendar months.
For example, September 26, 2016 was the first day of our October 2016 fiscal month.
(b) In October 2010, our Board of Directors approved a share repurchase program pursuant to which we are authorized to repurchase our common stock in privately negotiated transactions or in the open market at prices per share not exceeding the then-current market prices.
On September 22, 2016, our Board of Directors authorized a $2.0 billion increase to the program.
Under the program, management has discretion to determine the dollar amount of shares to be repurchased and the timing of any repurchases in compliance with applicable law and regulation.
This includes purchases pursuant to Rule 10b5-1 plans.
The program does not have an expiration date.
(c) During the quarter ended December 31, 2016, the total number of shares purchased included 11,393 shares that were transferred to us by employees in satisfaction of minimum tax withholding obligations associated with the vesting of restricted stock units.
These purchases were made pursuant to a separate authorization by our Board of Directors and are not included within the program.
