OPERATIONS


The following discussion should be read in conjunction with the consolidated
financial statements as of December 26, 2020 and December 28, 2019 and for each
of the three years in the period ended December 26, 2020 and related notes,
which are included in this Annual Report on Form 10-K as well as with the other
sections of this Annual Report on Form 10-K, including "Part I, Item 1:
Business," "Part II, Item 6: Selected Financial Data" and "Part II, Item 8:
Financial Statements and Supplementary Data."
Introduction
In this section, we will describe the general financial condition and the
results of operations of Advanced Micro Devices, Inc. and its wholly-owned
subsidiaries (collectively, "us," "our" or "AMD"), including a discussion of our
results of operations for 2020 compared to 2019, an analysis of changes in our
financial condition and a discussion of our contractual obligations and
off-balance sheet arrangements. Discussions of 2018 items and year-to-year
comparisons between 2019 and 2018 that are not included in this Form 10-K can be
found in "Management's Discussion and Analysis of Financial Condition and
Results of Operations" in Part II, Item 7 of our Annual Report on Form 10-K for
the fiscal year ended December 28, 2019.
Overview
During 2020, we continued to build on our technical, operational and financial
foundation to drive our long-term growth strategy. We delivered strong financial
results and further extended our industry-leading product portfolio despite the
backdrop of the COVID-19 pandemic. Net revenue for 2020 was $9.8 billion, an
increase of 45% compared to 2019 net revenue of $6.7 billion. Gross margin, as a
percentage of net revenue for 2020, was 45%, compared to 43% in 2019. Our
operating income for 2020 improved to $1.4 billion compared to operating income
of $631 million for 2019. Our net income for 2020 improved to $2.5 billion
compared to $341 million in the prior year. We recognized a $1.3 billion income
tax benefit upon the release of a portion of the valuation allowance on deferred
tax assets. We made significant progress towards improving our balance sheet in
2020. Cash, cash equivalents and short-term investments as of December 26, 2020
were $2.3 billion, compared to $1.5 billion at the end of 2019. The aggregate
principal amount of total debt as of December 26, 2020 was $338 million,
compared to $563 million as of December 28, 2019.
During 2020, we consistently executed our product roadmap and launched multiple
products in leading-edge manufacturing technologies. We introduced a number of 7
nanometer (nm) products during the year, including new additions to our 3rd Gen
AMD Ryzen™ desktop processor family, the AMD Ryzen 3 3100 and AMD Ryzen 3 3300X
for the mainstream market, and the AMD Ryzen 9 3900XT, AMD Ryzen 7 3800XT and
AMD Ryzen 5 3600XT processors for the enthusiast market. In July 2020, we
introduced the AMD Ryzen Threadripper™ PRO Processor family designed for
professional workstations from OEMs to system integrators and AMD Ryzen 4000
Series desktop processors with Radeon™ graphics for consumers, gamers, streamers
and creators. We also introduced AMD Athlon™ 3000 Series desktop processors
using the same Zen core architecture and built-in Radeon graphics as the AMD
Ryzen desktop processor family. Also, the AMD Ryzen PRO 4000 series and AMD
Athlon PRO 3000 series desktop processors were introduced for the commercial
market. In October 2020, we introduced the AMD Ryzen 5000 Series desktop
processor family powered by "Zen 3" core architecture. We also expanded our
notebook products in 2020. In May 2020, we announced the global availability of
the AMD Ryzen™ PRO 4000 Series Mobile family for commercial notebooks built with
enterprise-grade AMD PRO technologies, which deliver a set of security and
manageability features for Enterprise IT deployments. Also, we announced the AMD
Ryzen 3000 C-Series mobile processors and the AMD Athlon 3000 C-Series mobile
processors for Chromebook platforms designed for multi-tasking and content
creation in distance learning and remote working. With respect to our graphics
products, we expanded our professional offerings with the AMD Radeon™ Pro VII
workstation graphics card designed for broadcast and engineering professionals.
In August 2020, we announced the availability of the new AMD Radeon Pro 5000
series GPUs for the updated 27-inch iMac bringing a wide variety of graphically
intensive applications and workloads to consumer and professional users. We also
introduced the AMD Radeon RX 6000 Series graphics cards built on AMD RDNA™ 2
gaming architecture and designed for enthusiast-class PC gaming. In November
2020, we introduced our data center graphics processor, the AMD Instinct™ MI100
GPU accelerator, the first accelerator to use new AMD CDNA architecture
dedicated to HPC workloads.
We expanded our EPYC server family during the year. In April 2020, we announced
the extension of the 2nd Gen AMD EPYC processor family with three new
processors: AMD EPYC 7F32 (8 cores), AMD EPYC 7F52 (16 cores) and AMD EPYC 7F72
(24 cores). These new processors leverage up to 500 MHz of additional base
frequency and large amounts of cache. In October 2020, we announced the AMD
EPYC™ processor based Azure Dav4, Eav4,
                                       39
--------------------------------------------------------------------------------

Easv4 and Lsv2 VMs for use to improve real-time analysis on large volumes of
data streaming from applications, websites and more. We also expanded our
embedded processor family with two new AMD Ryzen Embedded R1000 low-power
processors that provide customers with a thermal design power (TDP) range of 6
up to 10 watts. In November 2020, we launched the AMD Ryzen Embedded V2000
series processor built on 7 nm process technology, "Zen 2" cores and
high-performance AMD Radeon graphics.
While the current COVID-19 pandemic continues to impact our business operations
and practices, and we expect that it may continue to impact our business, we
experienced limited financial disruption during 2020. Although many of our
offices remained open to enable critical on-site business functions in
accordance with local government guidelines, most of our employees worked from
home during 2020. During the second half of 2020, the majority of our employees
in China returned to work and we maintained normal business operations subject
to local government health measures. We continue to monitor and take measures to
protect the health and safety of our employees, and support those employees who
work from home so that they can be productive. We monitor demand signals as we
adjust our supply chain requirements based on changing customer needs and
demands. We also assess our product schedules and roadmaps to make any
adjustments that may be necessary to support remote working requirements and
address the geographic and market demand shifts caused by COVID-19.
As part of our strategy to establish AMD as the industry's high performance
computing leader, we announced in October 2020 that we entered into a definitive
agreement to acquire Xilinx, Inc. in an all-stock transaction. The transaction
is currently expected to close by the end of calendar year 2021.
We intend the discussion of our financial condition and results of operations
that follows to provide information that will assist in understanding our
financial statements, the changes in certain key items in those financial
statements from period to period, the primary factors that resulted in those
changes, and how certain accounting principles, policies and estimates affect
our financial statements.
Critical Accounting Estimates
Our discussion and analysis of our financial condition and results of operations
are based upon our consolidated financial statements, which have been prepared
in accordance with U.S. generally accepted accounting principles (U.S. GAAP).
The preparation of our financial statements requires us to make estimates and
judgments that affect the reported amounts in our consolidated financial
statements. We evaluate our estimates on an on-going basis, including those
related to our revenue, inventories, goodwill and income taxes. We base our
estimates on historical experience and on various other assumptions that we
believe to be reasonable under the circumstances, the results of which form the
basis for making judgments about the carrying values of assets and liabilities.
Although actual results have historically been reasonably consistent with
management's expectations, the actual results may differ from these estimates or
our estimates may be affected by different assumptions or conditions.
Management believes the following critical accounting estimates are the most
significant to the presentation of our financial statements and require the most
difficult, subjective and complex judgments.
Revenue Allowances. Revenue contracts with our customers include variable
amounts which we evaluate under ASC 606-10-32-8 through 14 in order to determine
the net amount of consideration to which we are entitled and which we recognize
as revenue. We determine the net amount of consideration to which we are
entitled by estimating the most likely amount of consideration we expect to
receive from the customer after adjustments to the contract price for rights of
return and rebates to our OEM customers and rights of return, rebates and price
protection on unsold merchandise to our distributor customers.
We base our determination of necessary adjustments to the contract price by
reference to actual historical activity and experience, including actual
historical returns, rebates and credits issued to OEM and distributor customers
adjusted, as applicable, to include adjustments, if any, for known events or
current economic conditions, or both.
Our estimates of necessary adjustments for distributor price incentives and
price protection on unsold products held by distributors are based on actual
historical incentives provided to distributor customers and known future price
movements based on our internal and external market data analysis.
Our estimates of necessary adjustments for OEM price incentives utilize, in
addition to known pricing agreements, actual historical rebate attainment rates
and estimates of future OEM rebate program attainment based on internal and
external market data analysis.
                                       40
--------------------------------------------------------------------------------

We offer incentive programs through cooperative advertising and marketing
promotions. Where funds provided for such programs can be estimated, we
recognize a reduction to revenue at the time the related revenue is recognized;
otherwise, we recognize such reduction to revenue at the later of when: i) the
related revenue transaction occurs; or ii) the program is offered. For
transactions where we reimburse a customer for a portion of the customer's cost
to perform specific product advertising or marketing and promotional activities,
such amounts are recognized as a reduction to revenue unless they qualify for
expense recognition.
We also provide limited product return rights to certain OEMs and to most
distribution customers. These return rights are generally limited to a
contractual percentage of the customer's prior quarter shipments, although, from
time to time we may approve additional product returns beyond the contractual
arrangements based on the applicable facts and circumstances. In order to
estimate adjustments to revenue to account for these returns, including product
restocking rights provided to distributor and OEM customers, we utilize
relevant, trended actual historical product return rate information gathered,
adjusted for actual known information or events, as applicable.
Overall, our estimates of adjustments to contract price due to variable
consideration under our contracts with OEM and distributor customers, based on
our assumptions and include adjustments, if any, for known events, have been
materially consistent with actual results; however, these estimates are subject
to management's judgment and actual provisions could be different from our
estimates and current provisions, resulting in future adjustments to our revenue
and operating results.
Inventory Valuation. We value inventory at standard cost, adjusted to
approximate the lower of actual cost or estimated net realizable value using
assumptions about future demand and market conditions. Material assumptions we
use to estimate necessary inventory carrying value adjustments can be unique to
each product and are based on specific facts and circumstances. In determining
excess or obsolescence reserves for products, we consider assumptions such as
changes in business and economic conditions, other-than-temporary decreases in
demand for our products, and changes in technology or customer requirements. In
determining the lower of cost or net realizable value reserves, we consider
assumptions such as recent historical sales activity and selling prices, as well
as estimates of future selling prices. If in any period we anticipate a change
in assumptions such as future demand or market conditions to be less favorable
than our previous estimates, additional inventory write-downs may be required
and would be reflected in cost of sales, resulting in a negative impact to our
gross margin in that period. If in any period we are able to sell inventories
that had been written down to a level below the ultimate realized selling price
in a previous period, related revenue would be recorded with a lower or no
offsetting charge to cost of sales resulting in a net benefit to our gross
margin in that period. Overall, our estimates of inventory carrying value
adjustments have been materially consistent with actual results.
Goodwill. We perform our goodwill impairment analysis as of the first day of the
fourth quarter of each year and, if certain events or circumstances indicate
that an impairment loss may have been incurred, on a more frequent basis. The
analysis may include both qualitative and quantitative factors to assess the
likelihood of an impairment.
We first analyze qualitative factors to determine if it is more likely than not
that the fair value of a reporting unit exceeds its carrying amount. Qualitative
factors include industry and market considerations, overall financial
performance, share price trends and market capitalization and Company-specific
events. If we conclude it is more likely than not that the fair value of a
reporting unit exceeds its carrying amount, we do not proceed to perform a
quantitative impairment test.
If we conclude it is more likely than not that the fair value of the reporting
unit is less than its carrying value, a quantitative goodwill impairment test
will be performed by comparing the fair value of each reporting unit to its
carrying value. A quantitative impairment analysis, if necessary, considers the
income approach, which requires estimates of the present value of expected
future cash flows to determine a reporting unit's fair value. Significant
estimates include revenue growth rates and operating margins used to calculate
projected future cash flows, discount rates, and future economic and market
conditions.
A goodwill impairment charge is recognized for the amount by which a reporting
unit's fair value is less than its carrying value, not to exceed the total
amount of goodwill allocated to that reporting unit.
Income Taxes. In determining taxable income for financial statement reporting
purposes, we must make certain estimates and judgments. These estimates and
judgments are applied in the calculation of certain tax liabilities and in the
determination of the recoverability of deferred tax assets which arise from
temporary differences between the recognition of assets and liabilities for tax
and financial statement reporting purposes.
                                       41
--------------------------------------------------------------------------------

We regularly assess the likelihood that we will be able to recover our deferred
tax assets. Unless recovery is considered more-likely-than-not (a probability
level of more than 50%), we will record a charge to income tax expense in the
form of a valuation allowance for the deferred tax assets that we estimate will
not ultimately be recoverable or maintain the valuation allowance recorded in
prior periods. When considering all available evidence, if we determine it is
more-likely-than-not we will realize our deferred tax assets, we will reverse
some or all of the existing valuation allowance, which would result in a credit
to income tax expense and the establishment of an asset in the period of
reversal.
In determining the need to establish or maintain a valuation allowance, we
consider the four sources of jurisdictional taxable income: (i) carryback of net
operating losses to prior years; (ii) future reversals of existing taxable
temporary differences; (iii) viable and prudent tax planning strategies; and
(iv) future taxable income exclusive of reversing temporary differences and
carryforwards.
Through the end of 2020, we demonstrated consistent, continued and increasing
profitability over the preceding three-year period. Our ability to sustain and
grow our profitability is supported by the continued positive momentum of our
consumer and commercial products, including our newly released desktop, mobile
and graphics processors, greater market acceptance for our server products, the
successful adoption of our new game console processor products, and our
leadership in the continued development of HPC products. In assessing the
realizability of the deferred tax assets, we considered the highly dynamic and
competitive landscape of our industry, the continued performance and market
acceptance of our new products, and the impact of such market acceptance on our
estimates of future profitability. As a result, in the fourth quarter of 2020,
we concluded that our history of profitable operating results, including the
current period results, along with increasingly favorable forecasts of continued
future profitability, provided sufficient positive evidence supporting the
realizability of a certain amount of our U.S. deferred tax assets, accordingly,
the release of the related valuation allowance previously recorded against these
deferred tax assets, resulting in a tax benefit of $1.3 billion in the fourth
quarter of 2020.
We continue to maintain a valuation allowance of approximately $1.6 billion for
certain federal, state, and foreign tax attributes. The federal valuation
allowance maintained is due to current limitations, including limitations under
Internal Revenue Code Section 382 or 383, separate return loss year rules, or
dual consolidated loss rules. The state and foreign valuation allowance
maintained is due to lack of sufficient sources of income.
In addition, the calculation of our tax liabilities involves addressing
uncertainties in the application of complex, multi-jurisdictional tax rules and
the potential for future adjustment of our uncertain tax positions by the
Internal Revenue Service or other taxing authorities. If our estimates of these
taxes are greater or less than actual results, an additional tax benefit or
charge could result.
Results of Operations
We report our financial performance based on the following two reportable
segments: the Computing and Graphics segment and the Enterprise, Embedded and
Semi-Custom segment.
Additional information on our reportable segments is contained in Note 14 -
Segment Reporting of the Notes to Financial Statements (Part II, Item 8 of this
Form 10-K).
Our operating results tend to vary seasonally. Historically, our net revenue has
been generally higher in the second half of the year than in the first half of
the year, although market conditions and product transitions could impact these
trends.
                                       42

Total operating income                 $ 1,369      $   631      $   451


Computing and Graphics
Computing and Graphics net revenue of $6.4 billion in 2020 increased by 37%,
compared to $4.7 billion in 2019, primarily as a result of a 37% increase in
unit shipments and a 2% increase in average selling price. The increase in unit
shipments was primarily due to higher demand for our Ryzen processors. The
increase in average selling price was primarily driven by a richer mix of client
processors from higher sales of our Ryzen processors, which have a higher
average selling price, partially offset by lower average selling price for our
Radeon products due to product cycle timing.
Computing and Graphics operating income was $1.3 billion in 2020 compared to
$577 million in 2019. The increase in operating income was primarily driven by
the margin contribution from higher sales which more than offset higher
operating expenses. Operating expenses increased for the reasons outlined under
"Expenses" below.
Enterprise, Embedded and Semi-Custom
Enterprise, Embedded and Semi-Custom net revenue of $3.3 billion in 2020
increased by 65% compared to net revenue of $2.0 billion in 2019, primarily
driven by higher sales of our EPYC server processors and higher semi-custom
revenue.
Enterprise, Embedded and Semi-Custom operating income was $391 million in 2020
compared to $263 million in 2019. The increase in operating income was primarily
due to the margin contribution from the increase in revenue which more than
offset higher operating expenses in 2020 and a $60 million licensing gain
recorded in 2019. Operating expenses increased for the reasons outlined under
"Expenses" below.
All Other
All Other operating loss of $288 million in 2020 included stock-based
compensation expense of $274 million and acquisition-related costs of $14
million.
All Other operating loss of $209 million in 2019 included $197 million of
stock-based compensation expense and a $12 million contingent loss accrual on a
legal matter.

Gross Margin
Gross margin as a percentage of net revenue was 45% in 2020 compared to 43% in
2019. The increase in gross margin was primarily driven by sales of Ryzen and
EPYC processors in 2020, which have a higher gross margin than the corporate
average, partially offset by sales of semi-custom products and Radeon products,
which have a lower gross margin than the corporate average.
Expenses
Research and Development Expenses
Research and development expenses of $2.0 billion in 2020 increased by $436
million, or 28%, compared to $1.5 billion in 2019. The increase was primarily
driven by an increase in product development costs in both the Computing and
Graphics and Enterprise and Embedded and Semi-Custom segments, due to an
increase in headcount and higher annual employee incentives driven by improved
financial performance.
Marketing, General and Administrative Expenses
Marketing, general and administrative expenses of $995 million in 2020 increased
by $245 million, or 33%, compared to $750 million in 2019. The increase was
primarily due to an increase in go-to-market activities in both the Computing
and Graphics and Enterprise, Embedded and Semi-Custom segments, and an increase
in headcount and higher annual employee incentives driven by improved financial
performance.
Licensing Gain

During 2019, we recognized $60 million as licensing gain associated with the
licensed IP to THATIC JV. See Note 4 of "Notes to Consolidated Financial
Statements" for additional information.
Interest Expense
Interest expense of $47 million in 2020 decreased by $47 million compared to $94
million in 2019, primarily due to lower debt balances.
Other Expense, Net
Other expense, net decreased in 2020 by $118 million from net of $165 million in
2019. Other expense, net for both periods primarily comprised of losses on
redemptions, repurchases and conversions of our outstanding debt and convertible
debt instruments.

Income Taxes Provision (Benefit)
Through the end of 2020, we demonstrated consistent, continued and increasing
profitability over the preceding three-year period. Our ability to sustain and
grow such profitability is supported by the continued positive momentum of our
consumer and commercial products including our newly released desktop, mobile
and graphics processors, greater market acceptance for our server products, the
successful adoption of our new game console processor products, and our
continued leadership in the development of HPC products. In assessing the
realizability of the deferred tax assets, we considered the highly dynamic and
competitive landscape of our industry, the continued performance and market
acceptance of our new products, and the impact of such market acceptance on
forecasts of future profitability. As a result, in the fourth quarter of 2020,
we concluded that our history of profitable operating results, including the
current period results, along with increasingly favorable forecasts of continued
future profitability, provided sufficient positive evidence supporting the
realizability of a certain amount of our U.S. deferred tax assets and,
accordingly, the release of the related valuation allowance previously recorded
against these deferred tax assets, resulting in a tax benefit of $1.3 billion in
the fourth quarter of 2020.
We continue to maintain a valuation allowance of approximately $1.6 billion for
certain federal, state, and foreign tax attributes. The federal valuation
allowance maintained is due to current limitations, including limitations under
Internal Revenue Code Section 382 or 383, separate return loss year rules, or
dual consolidated loss rules. The state and foreign valuation allowance
maintained is due to lack of sufficient sources of income.
We recorded an income tax benefit of $1.2 billion in 2020 and an income tax
provision of $31 million in 2019. The income tax benefit in 2020 was primarily
due to $1.3 billion of tax benefit from the valuation allowance release in the
U.S. This benefit was partially offset by approximately $10 million of
withholding tax expense related to cross-border transactions, $13 million of
state and foreign taxes, and a $75 million increase in valuation allowance
against certain state and foreign tax credits, which are reflected as part of
the state taxes and foreign rate benefit in the reconciliation table in the tax
footnote.
The income tax provision in 2019 was primarily due to $22 million of withholding
taxes related to cross-border transactions and $22 million of foreign income
taxes in profitable locations, partially offset by a $13 million benefit for a
reduction of U.S. income taxes accrued in the prior year.
International Sales
International sales as a percentage of net revenue were 77% in 2020 and 74% in
2019. We expect that international sales will continue to be a significant
portion of total sales in the foreseeable future. Substantially all of our sales
transactions are denominated in U.S. dollars.

We believe our cash, cash equivalents and short-term investments balance along
with our Revolving Credit Facility entered into in June 2019 (refer to Note 6 of
"Notes to Consolidated Financial Statements for additional information) will be
sufficient to fund operations, including capital expenditures, over the next 12
months. We believe we will be able to access the capital markets should we
require additional funds. However, we cannot assure that such funds will be
available on favorable terms, or at all.
Operating Activities
Our working capital cash inflows and outflows from operations are primarily cash
collections from our customers, payments for inventory purchases and payments
for employee-related expenditures.
Net cash provided by operating activities was $1.1 billion in 2020, primarily
due to our net income of $2.5 billion, adjusted for non-cash adjustments of
$488 million and net cash outflows of $931 million from changes in our operating
assets and liabilities. The primary drivers of the changes in operating assets
and liabilities included a $219 million increase in accounts receivable driven
primarily by $1.1 billion higher revenue in the fourth quarter of 2020 compared
to the fourth quarter of 2019, partially offset by higher collections due to
better revenue linearity in the fourth quarter of 2020 compared to the fourth
quarter of 2019, a $417 million increase in inventories driven by an increase in
product build in support of customer demand, a $231 million increase in prepaid
expenses and other assets due primarily to an increase in vendor credits, a $513
million decrease in accounts payable primarily due to timing of payments to our
suppliers, offset by a $574 million increase in accrued liabilities and other
driven by higher marketing accruals and higher accrued annual employee
incentives due to improved financial performance.
Net cash provided by operating activities was $493 million in 2019, primarily
due to our net income of $341 million, adjusted for non-cash and non-operating
charges of $694 million and net cash outflows of $542 million from changes in
our operating assets and liabilities. The primary drivers of the changes in
operating assets and liabilities included a $623 million increase in account
receivable driven primarily by $708 million higher revenue during the fourth
quarter of 2019 compared to the fourth quarter of 2018, a $137 million increase
in inventories driven by an increase in wafer purchases during the fourth
quarter of 2019 compared to the fourth quarter of 2018, and a $176 million
increase in prepaid expenses and other assets due primarily to an increase in
vendor credits and other non-current assets, partially offset by a $153 million
increase in accounts payable due to an increase in inventory purchases and a
$220 million increase in accrued liabilities and other driven by higher
marketing accruals.
Investing Activities
Net cash used in investing activities was $952 million in 2020, which primarily
consisted of $850 million for purchases of short-term investments and
$294 million for purchases of property and equipment, partially offset by
$192 million for maturities of short-term investments.
Net cash used in investing activities was $149 million in 2019, which primarily
consisted of $217 million for purchases of property and equipment, partially
offset by a net cash inflow from purchases and maturities of available-for-sale
debt securities of $41 million.
Financing Activities
Net cash provided by financing activities was $6 million in 2020, which
primarily consisted of proceeds from the issuance of common stock under our
employee equity plans of $85 million, partially offset by $78 million of common
stock repurchased to cover employee withholding taxes on vesting of employee
equity grants. We borrowed $200 million of short-term debt during the second
quarter of 2020 and paid off the balance during the third quarter of 2020.
Net cash provided by financing activities was $43 million in 2019, which
primarily consisted of a cash inflow of $449 million from the warrant exercised
by West Coast Hitech L.P. (WCH) and $74 million from the issuance of common
stock under our stock-based compensation equity plans, partially offset by $473
million of cash used for debt reduction activities during the year.

Contractual Obligations
The following table summarizes our consolidated principal contractual cash
obligations, as of December 26, 2020, and is supplemented by the discussion
following the table:
                                                                 Payment due by period
                                                                                                         2026 and
(In millions)                         Total        2021        2022       2023      2024      2025      thereafter
Term debt (1)                       $   338      $     -      $ 312      $  -      $  -      $  -      $        26
Aggregate interest obligation (2)        54           25         25         1         1         1                1

Operating leases (4)                    284           52         55        48        41        34               54
Purchase obligations (5)              3,032        2,971          7        15        15        15                9

Total contractual obligations (6) $ 3,867 $ 3,103 $ 463 $ 83 $ 67 $ 58 $ 93

(1) See Note 6 - Debt and Revolving Credit Facility of the Notes to Consolidated


            Financial Statements for additional information.

(2) Represents interest obligations, payable in cash, for our outstanding debt.

(3) Amounts primarily represent future fixed and non-cancellable cash payments


            associated with software technology and licenses and IP

licenses, including the


            payments due within the next 12 months.

(4) See Note 16 - Commitments and Guarantees of the Notes to Consolidated Financial


            Statements for additional information.

(5) Represents purchase obligations for goods and services where payments are based, in


            part, on the volume or type of services we acquire. In those 

cases, we only included


            the minimum volume of purchase obligations in the table above. 

Purchase orders for


            goods and services that are cancellable upon notice and without 

significant


            penalties are not included in the amounts above.

(6) Total amount excludes contractual obligations already recorded on our consolidated


            balance sheets except for debt obligations and other 

liabilities related to software


            and technology licenses and IP licenses.


The expected timing of payments of the obligations in the preceding table is
estimated based on current information. Timing of payments and actual amounts
paid may be different, depending on the timing of receipt of goods or services,
or changes to agreed-upon amounts for some obligations.
Our total gross unrecognized tax benefits were $119 million as of December 26,
2020. We have foreign and U.S. state tax audits in process at any one point in
time. At this time, we are unable to make a reasonably reliable estimate of the
timing of payments due to uncertainties in the timing of tax audit outcomes;
therefore, such amounts are not included in the above contractual obligations
table.
Off-Balance Sheet Arrangements
As of December 26, 2020, we had no off-balance sheet arrangements.
