General Overview



The Company is a leading independent provider of equipment and technology to the
upstream oil and gas industry. With operations in approximately 552 locations
across six continents, NOV designs, manufactures and services a comprehensive
line of drilling, well servicing and offshore construction equipment; sells and
rents drilling motors, specialized downhole tools, and rig instrumentation;
performs inspection and internal coating of oilfield tubular products; provides
drill cuttings separation, management and disposal systems and services; and
provides expendables and spare parts used in conjunction with the Company's
large installed base of equipment. NOV also manufactures coiled tubing and
high-pressure fiberglass and composite tubing and sells and rents advanced
in-line inspection equipment to makers of oil country tubular goods. More
recently, by applying its deep knowledge in technology, the Company has helped
advance the transition toward sustainable energy. The Company has a long
tradition of pioneering innovations which improve the cost-effectiveness,
efficiency, safety, and environmental impact of oil and gas operations.

NOV's revenue and operating results are principally directly related to the
level of worldwide oil and gas drilling and production activities and the
profitability and cash flow of oil and gas companies and drilling contractors,
which in turn are affected by current and anticipated prices of oil and gas. Oil
and gas prices have been and are likely to continue to be volatile. See Item 1A.
"Risk Factors". The Company conducts its operations through three business
segments: Wellbore Technologies, Completion & Production Solutions and Rig
Technologies. See Item 1. "Business", for a discussion of each of these business
segments.

Unless indicated otherwise, results of operations are presented in accordance
with accounting principles generally accepted in the United States ("GAAP").
Certain reclassifications have been made to the prior year financial statements
to conform with the 2021 presentation. The Company discloses Adjusted EBITDA
(defined as Operating Profit excluding Depreciation, Amortization, and, when
applicable, Other Items (as defined below under "Executive Summary")) in its
periodic earnings press releases and other public disclosures to provide
investors additional information about the results of ongoing operations. See
Non-GAAP Financial Measures and Reconciliations in Results of Operations for an
explanation of our use of non-GAAP financial measures and reconciliations to
their corresponding measures calculated in accordance with GAAP.

Operating Environment Overview



NOV's results are dependent on, among other things, the level of worldwide oil
and gas drilling, well remediation activity, the price of crude oil and natural
gas, capital spending by exploration and production companies and drilling
contractors, worldwide oil and gas inventory levels and, to a lesser degree, the
level of investment in wind, solar and geothermal energy products. Key industry
indicators for the past three years include the following:

EXECUTIVE SUMMARY

NOV Inc. generated revenue of $5.52 billion in 2021, which was lower from the
prior year as the Company entered the year with lower order backlog resulting
from sharply lower oil and gas prices and industry activity during 2020. While
industry activity began a slow recovery during 2021, the average 2021 worldwide
rig count (as measured by Baker Hughes) did not increase significantly when
compared to 2020.

For the year ended December 31, 2021, the Company reported an operating loss of
$134 million compared to an operating loss of $2,425 million in 2020, and a net
loss attributable to the Company of $250 million, or $0.65 per share compared to
a net loss of $2,542 million or $6.62 per share during 2020.

For the fourth quarter ended December 31, 2021, revenue was $1.52 billion, a
$176 million or 13 percent increase compared to the third quarter of 2021. The
Company reported a net loss of $40 million, or $0.10 per fully diluted share, an
improvement of $29 million, or $0.08 per fully diluted share, from the third
quarter of 2021. Compared to the fourth quarter of 2020, revenue increased $190
million or 14 percent, and net loss improved $307 million.

During the fourth quarter of 2021, third quarter of 2021, and fourth quarter of
2020, pre-tax other items: goodwill, intangible and long-lived asset impairment
charges, inventory charges, severance accruals, and other charges and credits
(collectively "Other Items"), were $9 million, $24 million, and $236 million,
respectively. Excluding the Other Items from all periods, fourth quarter 2021
Adjusted EBITDA was $69 million, compared to $56 million in the third quarter of
2021 and $17 million in the fourth quarter of 2020.

Segment Performance

Wellbore Technologies



Wellbore Technologies generated revenues of $576 million in the fourth quarter
of 2021, an increase of 14 percent from the third quarter of 2021 and an
increase of 54 percent from the fourth quarter of 2020. The increase in revenues
resulted from increased drilling activity levels in North America partially
offset by declines in international and offshore markets. Operating profit,
which included $(1) million in Other Items, was $50 million. Adjusted EBITDA
increased $11 million sequentially and $76 million from the prior year to $88
million, or 15.3 percent of sales.

Completion & Production Solutions



Completion & Production Solutions generated revenues of $549 million in the
fourth quarter of 2021, an increase of 15 percent from the third quarter of 2021
and an increase of 1 percent from the fourth quarter of 2020. Continued COVID-19
related operational challenges negatively impacted margin flow-through during
the quarter. Operating loss, which included $2 million in Other Items, was $16
million. Adjusted EBITDA increased $7 million sequentially and decreased $26
million from the prior year to $2 million, or 0.4 percent of sales.

New orders booked improved 29 percent sequentially to $495 million, representing
a book-to-bill of 159 percent when compared to the $311 million of orders
shipped from backlog. Backlog for capital equipment orders for Completion &
Production Solutions at December 31, 2021 was $1,287 million, an increase of
$592 million, or 85 percent from backlog of $695 million at December 31, 2020.

Rig Technologies generated revenues of $431 million in the fourth quarter of
2021, an increase of 11 percent from the third quarter of 2021 and a decrease of
1 percent from the fourth quarter of 2020. Increasing offshore drilling activity
levels resulting in lower capital equipment backlog contributed to the increase
in revenues in the fourth quarter of 2021 when compared to the third quarter of
2021. Operating profit, which included $3 million in Other Items, was $1
million. Adjusted EBITDA decreased $4 million sequentially and increased $2
million from the prior year to $21 million, or 4.9 percent of sales.

New orders booked during the quarter totaled $191 million, representing a
book-to-bill of 102 percent when compared to the $188 million of orders shipped
from backlog. At December 31, 2021, backlog for capital equipment orders for Rig

Oil & Gas Equipment and Services Market and Outlook



During 2020, the COVID-19 outbreak rapidly spread across the world, driving
sharp demand destruction for crude oil as countries took measures that curtailed
economic activity to slow the spread of the outbreak. Companies across the
industry responded with severe capital spending budget cuts, curtailed
production, cost reductions, personnel layoffs, facility closures and bankruptcy
filings. Towards the end of 2020 and into 2021, commodity prices stabilized and
began to recover resulting in improving industry activity levels in North
America.

Throughout 2021, greater availability of COVID-19 vaccines resulted in the
gradual reopening of certain economies around the world. Pent-up consumer and
industrial demand combined with government economic stimulus programs are
serving to amplify the global recovery, improve economic activity, and drive
higher demand for oil and gas, which management believes is setting the stage
for a global recovery in drilling activity. During 2021, oil and gas drilling
activity levels increased in every major region of the world, reflecting this
growing demand. However, supply chain disruptions and inflationary challenges
are significant and have continued into 2022.

Despite near-term disruptions from ongoing COVID-19 outbreaks, pandemic related
supply chain disruptions, and inflationary forces, management is optimistic that
improving market fundamentals and the actions NOV has taken to position its
business for the future will drive growth and improve profitability for the
Company. NOV remains committed to improving organizational efficiencies while
focusing on the development and commercialization of innovative products and
services, including environmentally friendly technologies, that are responsive
to the longer-term needs of NOV's customers. We believe this strategy will
further advance the Company's competitive position, regardless of the market.

--------------------------------------------------------------------------------

Other Items included in operating loss for Wellbore Technologies were $30 million for the year ended December 31, 2021 and $849 million for the year ended December 31, 2020.

Completion & Production Solutions



Revenue from Completion & Production Solutions for the year ended December 31,
2021 was $1,963 million, a decrease of $470 million (-19%) compared to the year
ended December 31, 2020.

Operating loss from Completion & Production Solutions was $65 million for the
year ended December 31, 2021 compared to an operating loss of $977 million for
2020, an improvement of $912 million. Operating loss percentage for 2021 was
-3.3 percent compared to -40.2 percent in 2020.

Included in operating loss are Other Items related to impairment charges,
inventory charges, severance accruals and other charges and credits. Other items
included in operating loss for Completion & Production Solutions was zero for
the year ended December 31, 2021 and $1,132 million for the year ended December
31, 2020.

The Completion & Production Solutions segment monitors its capital equipment
backlog to plan its business. New orders are added to backlog only when the
Company receives a firm written order for major completion and production
components or a signed contract related to a construction project. The capital
equipment backlog was $1,287 million at December 31, 2021, an increase of $592
million, or 85 percent from backlog of $695 million at December 31,
2020. Although numerous factors can affect the timing of revenue out of backlog
(including, but not limited to, customer change orders and supplier
accelerations or delays), the Company reasonably expects approximately $1,125
million of revenue out of backlog in 2022 and approximately $162 million of
revenue out of backlog in 2023 and thereafter. At December 31, 2021,
approximately 68 percent of the capital equipment backlog was for offshore
products and approximately 79 percent of the capital equipment backlog was
destined for international markets.

Rig Technologies



Revenue from Rig Technologies for the year ended December 31, 2021 was $1,739
million, a decrease of $180 million (-9%) compared to the year ended December
31, 2020.

Included in operating profit are Other Items related to severance and facility
closures, and asset write-downs. Other Items included in operating profit for
Rig Technologies were $20 million for the year ended December 31, 2021 and $402
million for the year ended December 31, 2020.

The Rig Technologies segment monitors its capital equipment backlog to plan its
business. New orders are added to backlog only when the Company receives a firm
written order for major drilling rig components or a signed contract related to
a construction project. The capital equipment backlog was $2,767 million at
December 31, 2021, an increase of $98 million, or 4 percent, from backlog of
$2,669 million at December 31, 2020.  Although numerous factors can affect the
timing of revenue out of backlog (including, but not limited to, customer change
orders and supplier accelerations or delays), the Company reasonably expects
approximately $692 million of revenue out of backlog in 2022 and the remaining
in 2023 and thereafter. At December 31, 2021, approximately 31 percent of the
capital equipment backlog was for offshore products and approximately 92 percent
of the capital equipment backlog was destined for international markets.

Eliminations and corporate costs



Eliminations and corporate costs were $186 million for the year ended December
31, 2021 compared to $228 million for the year ended December 31, 2020. This
change is primarily due to a decrease in intersegment sales. Sales from one
segment to another generally are priced at estimated equivalent commercial
selling prices; however, segments originating an external sale are credited with
the full profit to the Company. Eliminations and corporate costs include
intercompany transactions conducted between the three reporting segments that
are eliminated in consolidation, as well as corporate costs not allocated to the
segments. Intercompany transactions within each reporting segment are eliminated
within each reporting segment.

--------------------------------------------------------------------------------

Other income (expense), net



Other income (expense), net was expense of $23 million for the year ended
December 31, 2021 compared to expense of $17 million for the year ended December
31, 2020. The increase in expense was primarily due to higher foreign exchange
losses for 2021.

Provision for income taxes

The effective tax rate for the year ended December 31, 2021 was -6.5 percent,
compared to 8.7 percent for 2020. For the year ended December 31, 2021 the
effective tax rate was negatively impacted by current year losses in certain
jurisdictions with no tax benefit, partially offset by favorable adjustments
related to utilization of losses and tax credits for prior year tax returns. For
the year ended December 31, 2020 the effective tax rate was negatively impacted
by the impairment of nondeductible goodwill and the establishment of additional
valuation allowance for current year losses and other tax attributes, partially
offset by the release of valuation allowance as a result of (a) the carryback of
$591 million of U.S. net operating losses from 2019 to 2014 as a result of the
CARES Act and (b) the filing of an amended US tax return to deduct foreign tax
credits and carryback the resulting $287 million U.S. net operating loss from
2016 to 2014.






Results of Operations in 2020 Compared to 2019





Information related to the comparison of our operating results between the years
2020 and 2019 is included in "Item 7. Management's Discussion and Analysis of
Financial Condition and Results of Operations" of our 2020 Form 10-K filed with
the SEC and is incorporated by reference into this annual report on Form 10-K.



Non-GAAP Financial Measures and Reconciliations





This Form 10-K contains certain non-GAAP financial measures that management
believes are useful tools for internal use and the investment community in
evaluating NOV's overall financial performance. These non-GAAP financial
measures are broadly used to value and compare companies in the oilfield
services and equipment industry. Not all companies define these measures in the
same way. In addition, these non-GAAP financial measures are not a substitute
for financial measures prepared in accordance with GAAP and should therefore be
considered only as supplemental to such GAAP financial measures.



The Company defines Adjusted EBITDA as Operating Profit excluding Depreciation,
Amortization and, when applicable, Other Items. Management believes this is
important information to provide because it is used by management to evaluate
the Company's operational performance and trends between periods and manage the
business.  Management also believes this information may be useful to investors
and analysts to gain a better understanding of the Company's results of ongoing
operations. Adjusted EBITDA is not intended to replace GAAP financial measures,
such as Net Income.

Liquidity and Capital Resources



At December 31, 2021, the Company had cash and cash equivalents of $1,591
million, and total debt of $1,713 million. At December 31, 2020, cash and cash
equivalents were $1,692 million and total debt was $1,834 million. As of
December 31, 2021, approximately $893 million of the $1,591 million of cash and
cash equivalents was held by our foreign subsidiaries and the earnings
associated with this cash, if repatriated to the U.S., could be subject to
foreign withholding taxes and incremental U.S. taxation. If opportunities to
invest in the U.S. are greater than available cash balances that are not subject
to income tax, rather than repatriating cash, the Company may choose to borrow
against its revolving credit facility.

On April 8, 2021, the Company extended the maturity date of the revolving credit
facility by one additional year to October 30, 2025. The revolving credit
facility has a borrowing capacity of $2.0 billion through October 30, 2024, and
a borrowing capacity of $1.7 billion from October 31, 2024, to October 30, 2025.
The Company has the right to increase the commitments under this agreement to an
aggregate amount of up to $3.0 billion upon the consent of only those lenders
holding any such increase. Interest under the multicurrency facility is based
upon LIBOR, NIBOR or CDOR plus 1.125% subject to a ratings-based grid or the
U.S. prime rate. The credit facility contains a financial covenant regarding
maximum debt-to-capitalization ratio of 60%. As of December 31, 2021, the
Company was in compliance with a debt-to-capitalization ratio of 28% and had no
outstanding letters of credit issued under the facility, resulting in $2.0
billion of available funds.

The Company also has a $150 million bank line of credit for the construction of
a facility in Saudi Arabia. Interest under the bank line of credit is based upon
LIBOR plus 1.40%. The bank line of credit contains a financial covenant
regarding maximum debt-to-equity ratio of 75%. As of December 31, 2021, the
Company was in compliance. As of December 31, 2021, the Company had $102 million
in borrowings related to this line of credit. The first payment in December 2022
will be approximately $5 million.

On April 9, 2021, the Company repaid the entire outstanding balance of $182
million of its 2.60% unsecured Senior Notes due December 1, 2022 using available
cash balances. Upon redemption, the Company paid $191 million, which included a
redemption premium of $6.8 million as well as accrued and unpaid interest of
$1.7 million. As a result of the redemption, the Company recorded a loss on
extinguishment of debt of $7.1 million, which included the redemption premium of
$6.8 million and non-cash charges of $0.3 million to write-off of unamortized
discount and debt issuance costs. Following the repayment, the Company's
earliest bond maturity is in 2029.

The Company's outstanding debt at December 31, 2021 was $1,713 million and consisted of $494 million in 3.60% Senior Notes, $1,090 million in 3.95% Senior Notes, no commercial paper borrowings, and other debt of $129 million. The Company was in compliance with all covenants at December 31, 2021. Lease liabilities totaled $675 million at December 31, 2021.



The Company had $444 million of outstanding letters of credit at December 31,
2021 that are under various bilateral letter of credit facilities. Letters of
credit are issued as bid bonds, advanced payment bonds and performance bonds.

The following table summarizes our net cash provided by operating activities,
net cash used in investing activities and net cash used in financing activities
for the periods presented (in millions):



                                                Years Ended December 31,
                                              2021           2020       2019

(647 )

Significant sources and uses of cash during 2021

• Cash flows provided by operating activities was $291 million. This


        included changes in the primary components of our working capital
        (inventories, contract assets, and accounts payable).


  • Capital expenditures were $201 million.


  • Business acquisitions, net of cash acquired, were $52 million.


  • Payments of $20 million in dividends to our shareholders.

Other



The effect of the change in exchange rates on cash was a decrease of $7 million,
$2 million, and $8 million for the years ended December 31, 2021, 2020 and 2019,
respectively.

We believe that cash on hand, cash generated from operations and amounts available under our credit facilities and from other sources of debt will be sufficient to fund operations, working capital needs, capital expenditure requirements, dividends and financing obligations for the foreseeable future.



We may pursue additional acquisition candidates, but the timing, size or success
of any acquisition effort and the related potential capital commitments cannot
be predicted. We continue to expect to fund future cash acquisitions primarily
with cash flow from operations and borrowings, including the unborrowed portion
of the revolving credit facility or new debt issuances, but may also issue
additional equity either directly or in connection with acquisitions. There can
be no assurance that additional financing for acquisitions will be available at
terms acceptable to us.



As of December 31, 2021, the Company had $60 million of unrecognized tax
benefits. This represents the tax benefits associated with various tax positions
taken, or expected to be taken, on domestic and international tax returns that
have not been recognized in our financial statements due to uncertainty
regarding their resolution. Due to the uncertainty of the timing of future cash
flows associated with these unrecognized tax benefits, we are unable to make
reasonably reliable estimates of the period of cash settlement, if any, with the
respective taxing authorities. For further information related to unrecognized
tax benefits, see Note 15 to the Consolidated Financial Statements.

Critical Accounting Policies and Estimates



In preparing the financial statements, we make assumptions, estimates and
judgements that affect the amounts reported. We periodically evaluate our
estimates and judgements that are most critical in nature which are related to
revenue recognition under long-term construction contracts and impairment of
goodwill and other indefinite-lived intangible assets. Our estimates are based
on historical experience and on our future expectations that we believe are
reasonable. The combination of these factors forms the basis for making
judgements about the carrying values of assets and liabilities that are not
readily apparent from other sources. Actual results are likely to differ from
our current estimates and those differences may be material.

Revenue Recognition under Long-Term Construction Contracts



Revenue is recognized over-time for certain long-term construction contracts in
the Completion & Production Solutions and Rig Technologies segments. These
contracts include custom designs for customer-specific applications that are
unique and require significant engineering efforts.  Revenue is recognized as
work progresses on each contract. Right to payment is enforceable for
performance completed to date, including a reasonable profit.

We generally use the cost-to-cost (input) measure of progress for our contracts
because it best depicts the transfer of assets to the customer which occurs as
we incur costs. Estimating total revenue and cost at completion of long-term
construction contracts is complex, subject to many variables and requires
significant judgement. Under the cost-to-cost measure of progress, progress
towards completion of each contract is measured based on the ratio of costs
incurred to date to the total estimated costs at completion of the performance
obligation. Revenues, including estimated fees or profits, are recorded
proportionally as costs are incurred. These costs include labor, materials,
subcontractors' costs, and other direct costs. Any expected losses on a project
are recorded in full in the period in which the loss becomes probable.

These long-term construction contracts generally include integrating a complex set of tasks and components into a single project or capability, so are accounted for as one performance obligation.



It is common for our long-term contracts to contain late delivery fees, work
performance guarantees, and other provisions that can either increase or
decrease the transaction price. We estimate variable consideration as the most
likely amount we expect to receive. We include variable consideration in the
estimated transaction price to the extent it is probable that a significant
reversal of cumulative revenue recognized will not occur, or when the
uncertainty associated with the variable consideration is resolved. Our
estimates of variable consideration and determination of whether to include
estimated amounts in the transaction price are based on an assessment of our
anticipated performance and historical, current and forecasted information that
is reasonably available to us. Net revenue

                                       46

--------------------------------------------------------------------------------

recognized from performance obligations satisfied in previous periods was $38 million for the year ended December 31, 2021 primarily due to change orders.

Goodwill



The Company has approximately $1.5 billion of goodwill as of December 31, 2021.
Generally accepted accounting principles require the Company to test goodwill
for impairment at least annually or more frequently whenever events or
circumstances indicate that goodwill might be impaired. Events or circumstances
which could indicate a potential impairment include (but are not limited to) a
significant sustained reduction in worldwide oil and gas prices or drilling; a
significant sustained reduction in profitability or cash flow of oil and gas
companies or drilling contractors; a sustained reduction in the market
capitalization of the Company; a significant sustained reduction in capital
investment by drilling companies and oil and gas companies; or a significant
sustained increase in worldwide inventories of oil or gas.

The Company performs its goodwill test based on the Company's discounted cash
flow analysis. The discounted cash flow is based on management's forecast of
operating performance for each reporting unit. The two main assumptions used in
measuring goodwill impairment, which bear the risk of change and could impact
the Company's goodwill impairment analysis, include the cash flow from
operations from each of the Company's individual reporting units and the
weighted average cost of capital. The starting point for each of the reporting
unit's cash flow from operations is the detailed annual plan or updated
forecast. Cash flows beyond the specific operating plans were estimated using a
terminal value calculation, which incorporated historical and forecasted
financial cyclical trends for each reporting unit and considered long-term
earnings growth rates. The financial and credit market volatility directly
impacts our fair value measurement through our weighted average cost of capital
that we use to determine our discount rate. During times of volatility,
significant judgement must be applied to determine whether credit changes are a
short-term or long-term trend. The valuation techniques used in the annual test
were consistent with those used during previous testing. The inputs used in the
annual test were updated for current market conditions and forecasts.





Inventory Reserves



Inventory is carried at the lower of cost or estimated net realizable value. The
Company reviews historical usage of inventory on-hand, assumptions about future
demand and market conditions, current cost and estimates about potential
alternative uses, which are limited, to estimate net realizable value. The
Company's inventory consists of finished goods, spare parts, work in process,
and raw materials to support ongoing manufacturing operations and the Company's
large installed base of highly specialized oilfield equipment. The Company's
estimated carrying value of inventory depends upon demand largely driven by
levels of oil and gas well drilling and remediation activity, which depends in
turn upon oil and gas prices, the general outlook for economic growth worldwide,
available financing for the Company's customers, political stability and
governmental regulation in major oil and gas producing areas, and the potential
obsolescence of various types of equipment we sell, among other factors.



During 2021, 2020, and 2019 we recorded charges for additions to inventory
reserves of $73 million, $367 million, and $659 million, respectively,
consisting primarily of obsolete and surplus inventories. At December 31, 2021
and 2020, inventory reserves totaled $444 and $577 million, or 25.0% and 29.0%
of gross inventory, respectively.



Throughout the downturn the Company has continued to invest in developing and
advancing products and technologies, contributing to the obsolescence of certain
older products in a dramatically-shifted and more highly competitive recovering
market, but also ensuring that the portfolio of products and services offered by
the Company will meet customer needs in 2021 and beyond.



We will continue to assess our inventory levels and inventory offerings for our
customers, which could require the Company to record additional allowances to
reduce the value of its inventory. Such changes in our estimates or assumptions
could be material under weaker market conditions or outlook.







                                       47

--------------------------------------------------------------------------------

Income Taxes



The Company is U.S. registered and is subject to income taxes in the U.S. The
Company operates through various subsidiaries in a number of countries
throughout the world. Income taxes have been recorded based upon the tax laws
and rates of the countries in which the Company operates and income is earned.

The Company's annual tax provision is based on taxable income, statutory rates
and tax planning opportunities available in the various jurisdictions in which
it operates. The determination and evaluation of the annual tax provision and
tax positions involves the interpretation of the tax laws in the various
jurisdictions in which the Company operates. It requires significant judgement
and the use of estimates and assumptions regarding significant future events
such as the amount, timing and character of income, deductions and tax credits.
Changes in tax laws, regulations, and treaties, foreign currency exchange
restrictions or the Company's level of operations or profitability in each
jurisdiction could impact the tax liability in any given year. The Company also
operates in many jurisdictions where the tax laws relating to the pricing of
transactions between related parties are open to interpretation, which could
potentially result in aggressive tax authorities asserting additional tax
liabilities with no offsetting tax recovery in other countries.

The Company maintains liabilities for estimated tax exposures in jurisdictions
of operation. The annual tax provision includes the impact of income tax
provisions and benefits for changes to liabilities that the Company considers
appropriate, as well as related interest. Tax exposure items primarily include
potential challenges to intercompany pricing and certain operating expenses that
may not be deductible in foreign jurisdictions. These exposures are resolved
primarily through the settlement of audits within these tax jurisdictions or by
judicial means. The Company is subject to audits by federal, state and foreign
jurisdictions which may result in proposed assessments. The Company believes
that an appropriate liability has been established for estimated exposures under
the guidance in ASC Topic 740 "Income Taxes" ("ASC Topic 740"). However, actual
results may differ materially from these estimates. The Company reviews these
liabilities quarterly and to the extent audits or other events result in an
adjustment to the liability accrued for a prior year, the effect will be
recognized in the period of the event.

The Company currently has recorded valuation allowances that the Company intends
to maintain until it is more likely than not the deferred tax assets will be
realized. Income tax expense recorded in the future will be reduced to the
extent of decreases in the Company's valuation allowances. The realization of
remaining deferred tax assets is primarily dependent on future taxable income.
Any reduction in future taxable income including but not limited to any future
restructuring activities may require that the Company record an additional
valuation allowance against deferred tax assets. An increase in the valuation
allowance would result in additional income tax expense in such period and could
have a significant impact on future earnings.
