ANALOG DEVICES, INC.  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) A summary of the Company’s restricted stock unit award activity as of October 31, 2015 and changes during the fiscal year then ended is presented below:
## Table 0 ##
As of October 31, 2015, there was $108.8 million of total unrecognized compensation cost related to unvested sharebased awards comprised of stock options and restricted stock units.
That cost is expected to be recognized over a weightedaverage period of 1.3 years.
The total grant-date fair value of shares that vested during fiscal 2015, 2014 and 2013 was approximately $65.6 million, $57.4 million and $63.9 million, respectively.
Common Stock Repurchase Program The Company’s common stock repurchase program has been in place since August 2004.
In the aggregate, the Board of Directors have authorized the Company to repurchase $5.6 billion of the Company’s common stock under the program.
Under the program, the Company may repurchase outstanding shares of its common stock from time to time in the open market and through privately negotiated transactions.
Unless terminated earlier by resolution of the Company’s Board of Directors, the repurchase program will expire when the Company has repurchased all shares authorized under the program.
As of October 31, 2015, the Company had repurchased a total of approximately 140.7 million shares of its common stock for approximately $5.0 billion under this program.
An additional $544.5 million remains available for repurchase of shares under the current authorized program.
The repurchased shares are held as authorized but unissued shares of common stock.
The Company also, from time to time, repurchases shares in settlement of employee minimum tax withholding obligations due upon the vesting of restricted stock units or the exercise of stock options.
The withholding amount is based on the employees minimum statutory withholding requirement.
Any future common stock repurchases will be dependent upon several factors, including the Company's financial performance, outlook, liquidity and the amount of cash the Company has available in the United States.
Preferred Stock The Company has 471,934 authorized shares of $1.00 par value preferred stock, none of which is issued or outstanding.
The Board of Directors is authorized to fix designations, relative rights, preferences and limitations on the preferred stock at the time of issuance.4.
Industry, Segment and Geographic Information The Company operates and tracks its results in one reportable segment based on the aggregation of six operating segments.
The Company designs, develops, manufactures and markets a broad range of integrated circuits (ICs).
The Chief Executive Officer has been identified as the Company's Chief Operating Decision Maker.
The Company has determined that all of the Company's operating segments share the following similar economic characteristics, and therefore meet the criteria established for operating segments to be aggregated into one reportable segment, namely: ?
The primary source of revenue for each operating segment is the sale of integrated circuits.  ?
The integrated circuits sold by each of the Company's operating segments are manufactured using similar semiconductor manufacturing processes and raw materials in either the Company’s own production facilities or by third-party wafer fabricators using proprietary processes.  ?
The Company sells its products to tens of thousands of customers worldwide.
Many of these customers use products spanning all operating segments in a wide range of applications.  ?
The integrated circuits marketed by each of the Company's operating segments are sold globally through a direct sales force, third-party distributors, independent sales representatives and via our website to the same types of customers.
All of the Company's operating segments share a similar long-term financial model as they have similar economic characteristics.
The causes for variation in operating and financial performance are the same among the Company's operating segments and include factors such as (i) life cycle and price and cost fluctuations, (ii) number of competitors, (iii) product
During 2013, the Company retired $1,250 million of debt upon maturity.
The Company also extinguished $2,154 million of longterm debt prior to maturity, incurring associated extinguishment charges of $50 million.
The general terms of the notes that were extinguished were: ?
$225 million total principal amount of notes due August 15, 2013, at a fixed interest rate of 5.0 percent; ?
$675 million total principal amount of notes due March 3, 2014, at a fixed interest rate of 7.375 percent; ?

The Company’s long-term debt consisted of the following (in millions, except average rate data):
## Table 1 ##
1 These rates represent the weighted-average effective interest rate on the balances outstanding as of year end, as adjusted for the effects of interest rate swap agreements, cross currency swap agreements and fair value adjustments, if applicable.
Refer to Note 5 for a more detailed discussion on interest rate management.2 This amount is shown net of unamortized discounts of $23 million and $28 million as of December 31, 2015 and 2014, respectively.3 This amount includes adjustments recorded due to changes in foreign currency exchange rates.4 As of December 31, 2015, the amount shown includes $156 million of debt instruments that are due through 2031.5 Amount represents changes in fair value due to changes in benchmark interest rates.
Refer to Note 5 for additional information about our fair value hedging strategy.6 As of December 31, 2015 and 2014, the fair value of our long-term debt, including the current portion, was $31,308 million and $23,411 million, respectively.
The fair value of our long-term debt is estimated based on quoted prices for those or similar instruments.7 The above notes and debentures include various restrictions, none of which is presently significant to our Company.
The carrying value of the Company’s long-term debt included fair value adjustments related to the debt assumed from Coca-Cola Enterprises Inc. ’s (“Old CCE”) former North America business in 2010 of $411 million and $464 million as of December 31, 2015 and 2014, respectively.
These fair value adjustments are being amortized over the number of years remaining until the underlying debt matures.
As of December 31, 2015, the weighted-average maturity of the assumed debt to which these fair value adjustments relate was approximately 20 years.
The amortization of these fair value adjustments will be a reduction of interest expense in future periods, which will typically result in our interest expense being less than the actual interest paid to service the debt.
Total interest paid was $515 million, $498 million and $498 million in 2015, 2014 and 2013, respectively.
Maturities of long-term debt for the five years succeeding December 31, 2015, are as follows (in millions):
## Table 2 ##
Other Postretirement Benefit Plan Assets The following table summarizes the levels within the fair value hierarchy for our other postretirement benefit plan assets as of December 31, 2015 and 2014 (in millions):
## Table 3 ##
1 Level 3 assets are not a significant portion of other postretirement benefit plan assets.
Other Fair Value Disclosures The carrying amounts of cash and cash equivalents; short-term investments; receivables; accounts payable and accrued expenses; and loans and notes payable approximate their fair values because of the relatively short-term maturities of these financial instruments.
The fair value of our long-term debt is estimated using Level 2 inputs based on quoted prices for those instruments.
Where quoted prices are not available, fair value is estimated using discounted cash flows and market-based expectations for interest rates, credit risk and the contractual terms of the debt instruments.
As of December 31, 2015, the carrying amount and fair value of our long-term debt, including the current portion, were $31,084 million and $31,308 million, respectively.
As of December 31, 2014, the carrying amount and fair value of our long-term debt, including the current portion, were $22,615 million and $23,411 million, respectively.
