ANALOG DEVICES, INC.  NOTES TO CONSOLIDATED FINANCIALSTATEMENTS-(Continued)
## Table 0 ##
k.  Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure f of contingencies at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period.
Such estimates relate to the useful lives of fixed assets, identified intangible assets allowances for doubtful accounts and customer returns, the net realizable value of inventory, potential reserves relating to litigation matters, accrued liabilities, y accrued taxes, deferred tax valuation allowances, assumptions pertaining to share-based payments, and fair value of acquired assets and liabilities, including inventoryy, propertyy, plant and equipment and acquired intangibles, and other reserves.
Actual results could differ from those estimates and such dif f ferences may be material to the financial statements.
f l.  Concentrations of Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of investments and trade accounts receivable.
The Company maintains cash, cash equivalents and short-term and long-term investments with high credit quality counterparties, continuously monitors the amount of credit exposure to any one issuer and diversifies its investments in order to minimize its credit risk.
The Company sells its products to distributors and original equipment manufacturers involved in a variety of industries including industrial process automation, instrumentation, defense/aerospace, automotive, communications, computers and computer peripherals and consumer electronics.
The Company has adopted credit policies and standards to accommodate growth in these markets.
The Company performs continuing credit evaluations of its customers’ financial condition and although the Company generally does not require collateral, the Company may require letters of credit from customers in certain circumstances.
The Company provides reserves for estimated amounts of accounts receivable that may not be collected.
The Company's largest single end customer represented approximately14%, 12% and 13% of total revenue in fiscal years 2017, 2016 and 2015, respectively.
m.  Concentration of Other Risks The semiconductor industry is characterized by rapid technological change, competitive pricing pressures and cyclical market patterns.
The Company’s financial results are affected by a wide variety of factors, including general economic f conditions worldwide, economic conditions specific to the semiconductor industry, the timely implementation of new y manufacturing technologies, the ability to safeguard patents and intellectual property in a rapidly evolving market and reliance on assembly and test subcontractors, third-party wafer fabricators and independent distributors.
In addition, the semiconductor market has historically been cyclical and subject to significant economic downturns at various times.
The Company is exposed to the risk of obsolescence of its inventory depending on the mix of future business.
Additionallyy, a large portion of the Company’s purchases of external wafer and foundry services are from a limited number of suppliers, primarily Taiwan T Semiconductor Manufacturing Company (TSMC).
If TSMC or any of the Company’s other key suppliers are unable or unwilling to manufacture and deliver suffficient quantities of components, on the time schedule and of the quality that the Company requires, the Company may be forced to engage additional or replacement suppliers, which could result in significant expenses and disruptions or delays in manufacturing, product development and shipment of product to the Company’s
Warranties and Indemnities The Company generally warrants that its products sold to its customers will conform to the Company’s approved specifications and be free from defects in material and workmanship under normal use and service for one year.
Subject to certain exceptions, the Company also offers a three-year limited warranty to end users for only those CPU and AMD A-Series APU products that are commonly referred to as “processors in a box” and for PC workstation products.
The Company has also offered extended limited warranties to certain customers of “tray” microprocessor products and/or workstation 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 28, 2013 and December 29, 2012 are as follows:
## Table 1 ##
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 17: 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 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 plaintiff seeks to represent a proposed class of all persons who purchased or otherwise acquired AMD common stock during the period October 27, 2011 through October 28, 2012.
The complaint seeks damages allegedly caused by alleged materially misleading statements and/or material omissions by the Company and the individual officers regarding our 32nm technology and “Llano” product, which statements and omissions, the plaintiffs claim, allegedly operated to inflate artificially the price paid for AMD’s common stock during the period.
The complaint seeks unspecified compensatory damages, attorneys’ fees and costs.
Based upon information presently known to the Company’s management, the Company believes that the potential liability, if any, will not have a material adverse effect on our financial condition, cash flows or results of operations.
GUR is an engineered material used in heavy-duty automotive and industrial applications such as car battery separator panels and industrial conveyor belts, as well as in specialty medical and consumer applications, such as sports equipment and prostheses.
GUR micro powder grades are used for high-performance filters, membranes, diagnostic devices, coatings and additives for thermoplastics and elastomers.
GUR fibers are also used in protective ballistic applications.
Celstran and Compel are long fiber reinforced thermoplastics, which impart extra strength and stiffness, making them more suitable for larger parts than conventional thermoplastics.
Polyesters such as Celanex PBT, Vandar, a series of PBT-polyester blends and Riteflex, a thermoplastic polyester elastomer, are used in a wide variety of automotive, electrical and consumer applications, including ignition system parts, radiator grilles, electrical switches, appliance and sensor housings, LEDs and technical fibers.
Raw materials for polyesters vary.
Base monomers, such as dimethyl terephthalate and PTA, are widely available with pricing dependent on broader polyester fiber and packaging resins market conditions.
Smaller volume specialty co-monomers for these products are typically supplied by a few companies.
Liquid crystal polymers (“LCP”), such as Vectra, are used in electrical and electronics applications and for precision parts with thin walls and complex shapes or on high-heat cookware application.
Fortron, a PPS product, is used in a wide variety of automotive and other applications, especially those requiring heat and/or chemical resistance, including fuel system parts, radiator pipes and halogen lamp housings, and often replaces metal in these demanding applications.
Other possible application fields include non-woven filtration devices such as coal fired power plants.
Fortron is manufactured by Fortron Industries LLC, Advanced Engineered Materials’ 50-50 venture with Kureha Corporation of Japan.
Facilities Advanced Engineered Materials has polymerization, compounding and research and technology centers in Germany, Brazil and the United States.
On November 29, 2006, Advanced Engineered Materials reached a settlement with the Frankfurt, Germany, Airport (“Fraport”) to relocate its Kelsterbach, Germany, business, resolving several years of legal disputes related to the planned Frankfurt airport expansion.
The final settlement agreement was signed on June 12, 2007.
As a result of the settlement, Advanced Engineered Materials will transition its operations from Kelsterbach to the Hoechst Industrial Park in the Rhine Main area by 2011.
See Note 29 to the consolidated financial statements for further information.
Markets The following table illustrates the destination of the net sales of the Advanced Engineered Materials segment by geographic region for the years ended December 31, 2007, 2006 and 2005.
Net Sales to External Customers by Destination — Advanced Engineered Materials
## Table 2 ##
Advanced Engineered Materials’ sales in the Asian market are made mainly through its ventures, Polyplastics, KEPCO and Fortron Industries, which are accounted for under the equity method and therefore not included in Advanced Engineered Materials’ consolidated net sales.
If Advanced Engineered Materials’ portion of the sales made by these ventures were included in the chart above, the percentage of sales sold in Asia/Australia would be substantially higher.
A number of Advanced Engineered Materials’ POM customers, particularly in the appliance,
estimated at reporting dates prior to that time.
The compensation expense recognized each period should be based on the most recent estimated value.
The Company’s recording of compensation expenses prior to fiscal 2006 for these grants were an estimate based on grant date fair value.
Fiscal 2006 includes the effect of the change for that year.
The effect on years prior to fiscal 2006 was not material.
Further, in accordance with EITF 00-19, “Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company’s Own Stock,” the Company classifies these non-employee awards as liabilities at fair value upon vesting, with changes in fair value reported in earnings until these awards are exercised or forfeited.
The Company’s net income for the years ended September 30, 2007, September 30, 2006, and September 30, 2005 includes $7.0 million, $9.7 million, and $2.1 million, respectively, of compensation costs and $2.7 million, $3.7 million, and $804,000, respectively, net of income tax benefits related to option grants to its independent contractor Financial Advisors.
The fair value of each fixed option grant awarded to an independent contractor Financial Advisor is estimated on the date of grant and periodically revalued using the Black-Scholes option pricing model with the following weighted average assumptions used for fiscal years ended 2007, 2006, and 2005:
## Table 3 ##
The dividend yield assumption is based on the Company’s current declared dividend as a percentage of the stock price.
The expected volatility assumption for the current period and fiscal 2006 is based on the Company’s historical stock price and is a weighted average combining (1) the volatility of the most recent year, (2) the volatility of the most recent time period equal to the expected lives assumption, and (3) the annualized volatility of the price of the Company’s stock since the late 1980’s.
The expected volatility used by the Company in fiscal 2005 was based on the annualized volatility of the price of the Company’s stock since the late 1980’s.
The risk-free interest rate assumption is based on the U. S.  Treasury yield curve in effect at each point in time the options are valued.
The expected lives assumption is based on the difference between the option’s vesting date plus 90 days (the average exercise period) and the date of the current reporting period.
A summary of option activity of the Company's fixed stock option plans under which awards are granted to its independent contractor Financial Advisors for the year ended September 30, 2007 is presented below:
## Table 4 ##
As of September 30, 2007, there was $7.7 million of total unrecognized compensation cost related to unvested stock options granted to its independent contractor Financial Advisors based on estimated fair value at that date.
These costs are expected to be recognized over a weighted average period of approximately 2.3 years.
The weighted average grant date fair value of stock options granted under these plans during the years ended September 30, 2007, September 30, 2006 and September 30, 2005 was $9.70 per share, $11.87 per share and $9.51 per share, respectively.
The total intrinsic value of stock options exercised for these plans during the years ended September 30, 2007, September 30, 2006 and September 30, 2005 was $6.1 million, $5.6 million and $2.7 million, respectively.
The total estimated fair value of stock options vested for these plans during the years ended September 30, 2007, September 30, 2006 and September 30, 2005 was $6.2 million, $4.1 million and $3.5 million, respectively.
Cash received from stock option exercises for these plans for the year ended September 30, 2007 was $5.9 million.
There were no actual tax benefits realized for the tax deductions from option exercise of awards to its independent contractor Financial Advisors for the year ended September 30, 2007.
