PLX TECHNOLOGY, INC.


NOTES
TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


(Unaudited)







1.  Basis
of Presentation





The
accompanying unaudited condensed consolidated financial statements of PLX
Technology, Inc. and its wholly-owned subsidiaries (collectively, “PLX” or the
“Company”) as of September 30, 2009 and for the three and nine month periods
ended September 30, 2009 and 2008 have been prepared in accordance with
generally accepted accounting principles for interim financial information and
with the instructions to Form 10-Q and Article 10 of Regulation
S-X.  In the opinion of management, the unaudited condensed
consolidated financial statements include all adjustments (consisting only of
normal recurring accruals) that management considers necessary for a fair
presentation of the Company’s financial position, operating results and cash
flows for the interim periods presented. Subsequent events have been evaluated
through November 4, 2009, the date the condensed consolidated financial
statements were issued. Operating results and cash flows for interim periods are
not necessarily indicative of results for the entire year.





The
unaudited condensed consolidated financial statements include all of the
accounts of the Company and those of its wholly-owned
subsidiaries.  All intercompany accounts and transactions have been
eliminated.





This
financial data should be read in conjunction with the audited consolidated
financial statements and notes thereto included in our Annual Report on Form
10-K for the fiscal year ended December 31, 2008.





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 various accounts, including but not limited to
goodwill, acquired intangible assets, income taxes, inventories, revenue
recognition and related sales reserves, allowance for doubtful accounts,
share-based compensation and warranty reserves as reported in the financial
statements and accompanying notes.  Actual results could differ from
those estimates and such differences may be material to the financial
statements.





Comprehensive
Net Income (Loss)





The
Company’s comprehensive net income (loss) for the three and nine month periods
ended September 30, 2009 and 2008 was as follows (in thousands):

Revenue
Recognition





The
Company recognizes revenue when persuasive evidence of an arrangement exists,
delivery or customer acceptance, where applicable, has occurred, the fee is
fixed or determinable, and collection is reasonably assured.





Revenue
from product sales to direct customers and distributors is recognized upon
shipment and transfer of risk of loss, if the Company believes collection is
reasonably assured and all other revenue recognition criteria are met. The
Company assesses the probability of collection based on a number of factors,
including past transaction history and the customer’s creditworthiness.  At
the end of each reporting period, the sufficiency of allowances for doubtful
accounts is assessed based on the age of the receivable and the individual
customer’s creditworthiness.





7





As of
September 30, 2009 the Company offers pricing protection to two distributors
whereby the Company supports the distributor’s resale product margin on certain
products held in the distributor’s inventory. In general, the Company analyzes
current requests for credit in process, also known as ship and debits and
inventory at the distributor to determine the ending sales reserve required for
this program.  The Company also offers stock rotation rights to two
distributors such that they can return up to a total of 5% of products purchased
every six months in exchange for other products of the Company of equal value.
The Company analyzes current stock rotation requests and past experience to
determine the ending sales reserve required for this program.  In
addition, the Company has arrangements with a small number of customers offering
a rebate program on various products. The Company records rebates as a reduction
of revenue. Reserves are reduced directly from revenue and recorded as a
reduction to accounts receivable.





Recent
Accounting Pronouncements





In
December 2007, the Financial Accounting Standards Board (“FASB”) revised the
accounting guidance related to business combinations. This guidance establishes
principles and requirements intending to improve the relevance, representational
faithfulness and comparability of information that a reporting entity provides
in its financial reports about a business combination and its effects. This
guidance became effective for fiscal years beginning after December 15,
2008.  The adoption this guidance on January 1, 2009 changed the
Company’s accounting treatment for business combinations. Among other things,
acquisition related costs are required to be expensed as incurred. On January 2,
2009 we completed the acquisition of Oxford and as a result, the Company
expensed acquisition related costs of $0.8 million and $0.4 million in the
fourth quarter of 2008 and the nine months ended September 30, 2009,
respectively.





In
April 2009 the FASB issued new accounting guidance related to assets
acquired and liabilities assumed in a business combination. This guidance amends
the provisions previously issued related to the initial recognition and
measurement, subsequent measurement and accounting, and disclosures for assets
and liabilities arising from contingencies in business combinations. The new
guidance eliminates the distinction between contractual and non-contractual
contingencies, including the initial recognition and measurement. This guidance
is effective for contingent assets and contingent liabilities acquired in
business combinations for which the acquisition date is on or after the
beginning of the first annual reporting period beginning on or after
December 15, 2008. The adoption of this guidance did not have a material
impact on the Company’s financial position or results of
operations.





In
December 2007, the FASB issued new accounting guidance related to noncontrolling
interests in consolidated financial statements. This guidance establishes
accounting and reporting standards to improve the relevance, comparability and
transparency of financial information that a reporting entity provides in its
consolidated financial statements. This guidance became effective December 15,
2008. The adoption of this guidance did not have a material impact on the
Company’s financial position or results of operations.





In
February 2008, the FASB issued new accounting guidance which delayed the
effective date to fiscal years ending after November 15, 2008 for fair value
accounting for all non-financial assets and liabilities, except those that are
recognized or disclosed at fair value in the financial statements on a recurring
basis. This guidance became effective November 15, 2008. The adoption of
this guidance did not have a material impact on the Company’s financial position
or results of operations.





In April
2008, the FASB issued new accounting guidance related to the determination of
the useful life of intangible assets. This guidance amends the factors an entity
should consider in developing renewal or extension assumptions used in
determining the useful life of recognized intangible assets and adds certain
disclosures for an entity’s accounting policy of the treatment of the costs,
period of extension, and total costs incurred.  This guidance must be
applied prospectively to intangible assets acquired after January 1,
2009.  The adoption of this guidance did not have a material impact on
the Company’s financial position or results of operations.





In April
2009, the FASB issued three related sets of accounting guidance intended to
enhance disclosures regarding fair value measurements and impairments of
securities. This guidance sets forth rules related to determining the fair value
of financial assets and financial liabilities when the activity levels have
significantly decreased in relation to the normal market, guidance related to
the determination of other-than-temporary impairments to include intent and
ability of the holder as an indicator in the determination of whether an
other-than-temporary exists and interim disclosure requirements for the fair
value of financial instruments. These sets of accounting guidance became
effective June 15, 2009. The adoption of this guidance did not have a material
impact on the Company’s consolidated financial statements.





8





In April
2009, the FASB issued new accounting guidance related to the accounting and
disclosure of events that occur after the balance sheet date but before
financial statements are issued or available to be issued. We adopted this
guidance for the quarter ending June 30, 2009. Adoption did not have a
material impact on our consolidated financial statements. See Note 1 to the
accompanying condensed consolidated financial statements for the related
disclosure.





In June
2009, the FASB issued the FASB Accounting Standards Codification (ASC). The ASC
has become the authoritative source of generally accepted accounting principles
in the United States. Rules and interpretive releases of the Securities and
Exchange Commission (SEC) under federal securities laws are also sources of
authoritative GAAP for SEC registrants. ASC became effective for financial
statements issued for interim and annual periods ending after September 15,
2009. The adoption of ASC did not have a material impact on the Company’s
consolidated financial statements.





2.  Share-Based
Compensation





Stock
Option Plans





In May
2008, the Company’s stockholders approved the 2008 Equity Incentive Plan (“2008
Plan”).  Under the 2008 Plan, there is authorized for issuance and
available for awards an aggregate of 1,200,000 shares of the Company’s common
stock, plus the number of shares of the Company’s common stock available for
issuance under the Company’s prior incentive plan, its 1999 Stock Incentive
Plan, that were not subject to outstanding awards as of May 27,
2008.  In addition, the share reserve under the 2008 Plan will be
increased by the number of shares issuable pursuant to awards outstanding under
the prior plan that would have otherwise reverted to the prior plan because such
awards expire, are canceled or otherwise terminated without being exercised.
Awards under the 2008 Plan may include stock options, restricted stock, stock
appreciation rights, performance awards, restricted stock units and other
awards, provided that with respect to full value awards, such as restricted
stock or restricted stock units, no more than 300,000 shares may be issued in
the form of full value awards during the term of the 2008
Plan.  Awards under the 2008 Plan may be made to the Company’s
officers and other employees, its board members and consultants that it
hires.  The 2008 Plan has a term of ten years.





Share-Based
Compensation Expense





The fair
value of share-based awards to employees is calculated using the Black-Scholes
option pricing model, which requires subjective assumptions, including future
stock price volatility and expected time to exercise, which greatly affect the
calculated values.





The
weighted-average fair value of share-based compensation to employees is based on
the multiple option valuation approach. Forfeitures are estimated and it is
assumed no dividends will be declared. The estimated fair value of share-based
compensation awards to employees is amortized using the straight-line method
over the vesting period of the options. The weighted-average fair value
calculations are based on the following weighted average
assumptions:

Risk-Free Interest Rate: The
risk-free interest rate is based on the U.S. Treasury yield curve in effect at
the time of grant for the expected term of the option.





Expected Term: The Company’s
expected term represents the weighted-average period that the Company’s stock
options are expected to be outstanding. The expected term is based on the
observed and expected time to post-vesting exercise of options by employees. The
Company uses historical exercise patterns of previously granted options in
relation to stock price movements to derive an employee behavioral pattern used
to forecast expected exercise patterns.





Expected Volatility: The
Company has historically calculated its expected volatility assumption required
in the Black-Scholes model by blending the historical and implied volatility.
The historical volatility is based on the weekly closing prices of its common
stock over a period equal to the expected term of the option. Market based
implied volatility is based on utilizing market data of actively traded options
on the Company’s stock, from options at- or near-the-money traded options, at a
point in time as close to the grant of the employee options as reasonably
practical and with similar terms to the employee share option, or a remaining
maturity of at least six months if no similar terms are available. The
historical volatility of the price of the Company’s common stock over the
expected term of the option is a strong indicator of the expected future
volatility. In addition, implied volatility takes into consideration market
expectations of how future volatility will differ from historical
volatility.  Historically, the Company did not believe that one
estimate was more reliable than the other so it used a 50/50 blend of historical
volatility and market-based volatility. However, due to the recent lack of
available market data to calculate implied volatility, the Company began using
100% historical volatility during the fourth quarter of 2008.

These
factors could change in the future, which would affect the share-based
compensation expense in future periods.

Company’s common stock were validly tendered and not withdrawn, and the Company
accepted the repurchase of these options.  Each eligible optionee who
validly tendered eligible options pursuant to the offer to purchase received a
cash payment in the range of $0.05 to $1.42 per option for an aggregate amount
of $0.9 million.  The Company recognized $1.6 million in share-based
compensation expenses associated with the acceleration of unamortized
compensation expenses on the previously unvested tendered options in the second
quarter of 2009. The aggregate amount of the payments made in exchange for
eligible options was charged to stockholders' equity to the extent that the
amount did not exceed the fair value of the eligible options accepted for
payment, as determined at the purchase date. The amount paid in excess of that
fair value of $16,000, as determined at the purchase date, was also recorded as
compensation expense.





The
Company returned to its 2008 Equity Incentive Plan the first 400,000 shares
underlying options purchased pursuant to the offer that were originally issued
under the 2008 plan or our 1999 Stock Incentive Plan.  These options
have become available for future grant. The Company retired the remaining
2,133,278 tendered options.

The
Company evaluates the need for potential inventory provisions by considering a
combination of factors including the life of the product, sales history,
obsolescence and sales forecasts.





4.  Net

As the
Company incurred a net loss for the three and nine month periods ended September
30, 2009, the effect of dilutive securities, totaling 2.8 million shares has
been excluded from the computation of diluted loss per share, as its impact
would be anti-dilutive. Dilutive securities are comprised of options to purchase
common stock.





Weighted
average employee stock options to purchase approximately 4.0 million and 4.1
million shares for the three and nine month periods ended September 30, 2008
were outstanding, but were not included in the computation of diluted earnings
per share because the exercise price of stock options was greater than the
average share price of the Company’s stock and, therefore, the effect would have
been anti-dilutive.





5.  Fair
Value Measurements





The
accounting guidance for fair value measurements provided a framework for
measuring fair value and expands related disclosures. Fair value is defined as
the price that would be received for an asset or the exit price that would be
paid to transfer a liability in the principal or most advantageous market in an
orderly transaction between market participants on the measurement date. The
guidance also established a hierarchy which requires an entity to maximize the
use of observable inputs, when available.  The guidance requires fair
value measurement be classified and disclosed in one of the following three
categories:





Level 1:
Valuations based on quoted prices in active markets for identical assets and
liabilities.  The fair value of available-for-sale securities included
in the level 1 category is based on quoted prices that are readily and regularly
available in an active market.





Level 2: Valuations based on observable
inputs (other than Level 1 prices), such as quoted prices for similar assets at
the measurement date; quoted prices in markets that are not active; or other
inputs that are observable, either directly or indirectly. The fair value of
available-for-sale securities included in the Level 2 category is based on the
market values obtained from an independent pricing service that were evaluated
using pricing models that vary by asset class and may incorporate available
trade, bid and other market information and price quotes from well established
independent pricing vendors and broker-dealers.





Level 3:
Valuations based on inputs that are unobservable and involve management judgment
and the reporting entity’s own assumptions about market participants and
pricing.





The fair
value of financial assets and liabilities measured on a recurring basis is as
follows (in thousands):

6.  Investments





As of
September 30, 2009 and December 31, 2008, the Company’s securities consisted of
debt securities and were designated as available-for-sale. Available-for-sale
securities are carried at fair value, based on quoted market prices, with
unrealized gains and losses reported in a separate component of stockholders’
equity.  The amortized cost of debt securities is adjusted for the
amortization of premiums and the accretion of discounts to maturity, both of
which are included in interest income.  Realized gains and losses are
recorded on the specific identification method.

The
Company compares the carrying value of its available for sale investments with
their quoted market prices at the end of each period.  If the quoted
price of a marketable security has dropped significantly during a period or has
been below our carrying value for an extended period of time, the Company
reviews the investment to determine whether the decline is other than
temporary.  If the Company determines that the decline is other than
temporary, the investment is written down to its market value as measured at the
end of the period.  Any resulting charge is included in the Company’s
statement of operations in the related period. The Company has not recorded any
other than temporary impairment charges in the accompanying financial
statements.





7.  Acquisition
of Oxford Semiconductor Inc.





On
January 2, 2009, the Company acquired all of the outstanding shares of capital
stock of Oxford Semiconductor, Inc. (Oxford), a privately held fabless provider
of industry-leading silicon and software for the consumer and small office/home
office (SOHO) storage markets.





Established
in 1992, Oxford has been providing silicon and software solutions to
interconnect digital systems, including PCIe, USB, FireWire, Ethernet, SATA and
eSATA.  Oxford’s corporate headquarters were located in Milpitas,
California, with most of its employees based in Oxford’s design center in
Abingdon, United Kingdom.  The consumer and SOHO external storage
markets account for the majority of Oxford’s sales.  Oxford provides
advanced system-on-chip solutions for both direct-attached storage (DAS) and
network-attached storage (NAS) external drives.  Oxford’s customers
include Seagate, Western Digital, LaCie, Hewlett Packard, and
Macpower.





14





We
believe that through this acquisition, we have a leadership position in two of
the fastest-growing interconnect chip markets – PCI Express-based systems and
consumer external storage.  Major synergies include common
interconnect technologies and design flows, sales, marketing and support
systems, and supply chains.  Most importantly, we can create
innovative products that combine the considerable intellectual property and
industry knowledge of Oxford and PLX.





The total
consideration paid for the transaction was $16.4 million, consisting of 5.6
million shares at $1.82 per share, the closing price on January 2, 2009, the
date the transaction was closed, and the fair value of the contingently
convertible debt liability as of January 2, 2009, of $6.2 million.


As a part
of the Merger Agreement, the Company acquired all of the outstanding shares of
capital stock of Oxford in exchange for 5.6 million shares of common stock of
PLX and a promissory note in the principal amount of $14.2 million (the “Note”)
that was to be satisfied by either (i) the issuance of an additional 3.4 million
shares of common stock of PLX upon approval of PLX’s stockholders, or (ii) the
repayment of the principal amount of the Note if such stockholder approval was
not obtained by June 30, 2009.  On May 22, 2009 at a special meeting
of the shareholders, the shareholders approved the conversion of the $14.2
million note to 3.4 million shares of common stock of the Company.
 
 Under the
revised business combinations guidance, which became effective for the Company
on January 1, 2009, the contingently convertible promissory note was considered
contingent consideration which is recorded at fair value as of the acquisition
date, and changes to the fair value of contingent consideration are reflected
through the statement of operations.  The fair value of the
convertible note on the acquisition date was based on that day’s closing stock
price of $1.82 per share.  On March 31, 2009, the convertible note was
remeasured to fair value. Based on the closing stock price of $2.17 as of March
31, 2009, the fair value of the convertible note was $7.4 million. The change in
fair value of $1.2 million was recognized as a loss in the quarter ended March
31, 2009. On May 22, 2009, the date of the conversion, the closing stock price
was $2.95. The fair value of the 3.4 million shares was $10.0
million.  The change in fair value of $2.7 million was recognized as a
loss in the second quarter of 2009.
 
 The

date.

The fair
value of assets acquired include trade receivables of $1.6
million.  The gross amount due under sales related contracts is $1.6
million, of which $0.3 million is expected to be uncollectible as a result of
recognized credits due to distributors for the difference in the price they
previously purchased products for from Oxford Semiconductor, Inc. and the
authorized quote price based on the distributors’ sell through
activity.  The gross amount under a prior IP royalty arrangement is
$0.3 million and the full amount is expected to be uncollectible.





15





The
identified intangible assets consist of core technology, trade name and customer
relationships.  The valuation of the acquired intangibles is
classified as a level 3 measurement under the fair value measurement guidance,
because the valuation was based on significant unobservable inputs and involved
management judgment and assumptions about market participants and
pricing.   In determining fair value of the acquired intangible
assets, we determined the appropriate unit of measure, the exit market and the
highest and best use for the assets. The fair value was estimated using an
incremental income approach.





The
goodwill arising from the acquisition is largely attributable to the synergies
expected to be realized after the Company’s acquisition and integration of
Oxford.  The Company only has one operating segment, semiconductor
products, so all of the goodwill was assigned to the one
segment.  Goodwill is not expected to be deductible for tax
purposes.





Oxford
contributed revenues and gross profit of $7.5 million and $3.9 million,
respectively, to the Company for the quarter ended September 30, 2009 and $19.2
and $9.5 million, respectively, for the period from January 2, 2009 to September
30, 2009.  Oxford operations were fully integrated as of the end of
the first quarter of 2009 and if is therefore not practicable to identify
earnings associates with Oxford’s contribution.





Because
the acquisition took place on January 2, 2009, which was in substance the
beginning of the year, no pro forma data is presented for the quarter or year to
date ended September 30, 2009 as the Company’s historical statement of
operations already includes the results of Oxford for the entire period. The
following unaudited pro forma summary presents consolidated information of the
Company as if the business combination occurred on January 1, 2008.

            $
            (5,601
            )





The pro
forma amounts have been calculated after applying the Company’s accounting
policies and adjusting the results of Oxford to reflect the amortization that
would have been recorded assuming the intangible assets had been acquired on
January 1, 2008.





During
the nine months ended September 30, 2009, the Company incurred $0.4 million of
third party acquisition related costs, primarily for outside legal and
accounting costs.  These expenses were included in operating expenses
under acquisition related costs in the Company’s consolidated statement of
operations for the nine months ended September 30, 2009.





8.  Goodwill
and Intangibles





As
discussed in Note 7, the acquisition of Oxford included the acquisition of $9.1
million of identifiable intangible assets.  All of these intangibles
are subject to amortization.  There is no estimated residual value on
any of the intangible assets.





The
following table summarizes the gross carrying amount and accumulated
amortization for each major intangible class and the weighted average
amortization period, in total and by major intangible asset class, as of
September 30, 2009 (in thousands).

Amortization
expense for the three and nine month periods ended September 30, 2008 was $0.2
million and $0.6 million, respectively, was related to the amortization of
intangibles acquired through our prior acquisitions of HiNT Corporation and
NetChip Technology, Inc.  As of December 31, 2008, the Company
determined that these assets were impaired and the remaining carrying value of
$0.8 million was written off.

10.  Restructuring
Costs





Severance





In the
first nine months of 2009, the Company recorded approximately $2.0 million of
severance and benefit related costs, included in acquisition related costs in
the Condensed Consolidated Statement of Operations, related to the termination
of 53 employees as a result of the redundancy issue associated with the
acquisition of Oxford. As of September 30, 2009 approximately $1.9 million of
the $2.0 million severance and benefit related costs was paid, and the remaining
$13,000 is included in accrued compensation and benefits in the Condensed
Consolidated Balance Sheet. The Company expects all severance and benefit
accruals to be paid by March 31, 2010.





In
September 2009, as a result of cost reduction efforts, the Company recorded
approximately $0.1 million of severance costs associated with the downsizing of
the Company’s R&D facility in Singapore. As of September 30, 2009, all
severance costs have been paid.





Lease
Termination





In
January 2009, associated with the acquisition of Oxford, the company acquired a
building lease in Milpitas, California which was vacated upon acquisition. The
Company has not been able to find a sublease for this property given the current
market conditions and available space in the area. The future lease costs for
the property were $0.3 million which extends through February 2010. The Company
recorded the liability, included in other accrued expenses in the Condensed
Consolidated Balance Sheet, for the costs to be incurred at the future cash
payment amount of $0.3 million as the total cash payment is not materially
different from the fair value. The lease accrual charge of $0.3 million was
recorded in the Condensed Consolidated Statement of Operations in the first
quarter of 2009. The Company expects the accrued lease liability to be paid in
full by February 2010.





11.  Stock
Repurchase





In
September 2002, the Company’s Board of Directors authorized the repurchase of up
to 2,000,000 shares of the Company’s common stock. In July 2008, the
Company’s Board of Directors authorized an additional 2,000,000 shares under the
repurchase program.  At the discretion of the management, the Company can
repurchase the shares from time to time in the open market or in privately
negotiated transactions.  Approximately 774,000 shares were repurchased for
approximately $1.9 million in cash in 2002 and 2003. The Company did not
repurchase any additional shares from January 1, 2004 through December 31, 2007.
In 2008, the Company repurchased 956,000 shares for approximately $6.5 million.
The Company did not repurchase any additional shares during the three or nine
months ended September 30, 2009.

12.  Segments
of an Enterprise and Related Information





The
Company has one operating segment, the sale of semiconductor devices. The Chief
Executive Officer has been identified as the Chief Operating Decision Maker
(“CODM”) because he has final authority over resource allocation decisions and
performance assessment. The CODM does not receive discrete financial information
about individual components of the Company’s business. The majority of the
Company’s assets are located in the United States.

13.  Income
Taxes





An income
tax benefit of $6,000 has been recorded for the nine month period ended
September 30, 2009, compared to a provision of $0.4 million for the same period
in 2008.  Income tax benefit for the nine months ended September 30,
2009 is a result of applying the estimated annual effective tax rate to
cumulative loss before taxes adjusted for certain discrete items which are fully
recognized in the period they occur.  For the same period in 2008, the
income tax expense was calculated on a year-to-date discrete basis due to the
uncertainty of fourth quarter operating estimates and large variability to the
annual effective rate based on small changes to ordinary income for the
year.





The
Company has determined that negative evidence supports the need for a full
valuation allowance against its net deferred tax assets at this time. The
Company will maintain a full valuation allowance until sufficient positive
evidence exists to support a reversal of the valuation allowance.





As of
September 30, 2009, the Company had unrecognized tax benefits of approximately
$2.5 million of which none, if recognized, would result in a reduction of the
Company’s effective tax rate.  There were no material changes in the
amount of unrecognized tax benefits during the nine months ended September 30,
2009. Future changes in the balance of unrecognized tax benefits will have no
impact on the effective tax rate as they are subject to a full valuation
allowance. The Company does not believe the amount of its unrecognized tax
benefits will significantly change within the next twelve months.





The
Company is subject to taxation in the United States and various states and
foreign jurisdictions.  The tax years 1998 through 2008 remain open to
examination by the federal and most state tax authorities due to certain
acquired net operating loss and overall credit carryforward
positions.

OVERVIEW





PLX
Technology, Inc. ("PLX" or the "Company"), a Delaware corporation established in
1986, designs, develops, manufactures, and sells integrated circuits for
interconnect applications.  These interconnect products are a
fundamental building block for standards-based subsystems.  We market
our products to major customers that sell electronic systems in the server,
storage, communications, industrial, and consumer markets.





Products
based on current serial interconnect technology standards such as PCI Express,
USB, SATA, and Ethernet provide capabilities to customers that previous parallel
technologies did not.  They offer the ability for systems to scale in
performance and capabilities, and allow for a standards-based building block
approach that was not feasible in the past.  As these serial
technologies have become mainstream, we have been able to offer differentiated
products based on standard ports that provide scalability and performance at a
high-volume price point.





19





PLX is
the market share leader in PCI Express switches and bridges.  We
recognized the trend towards this serial, switched interconnect technology
early, launched products for this market long before our competitors, and have
deployed multiple generations of products to serve a general-purpose, horizontal
market.  In addition to enabling customer differentiation through our
product features, the breadth of our product offering is in itself a significant
benefit to our customers, since we can serve the complete needs of our customers
with cost-effective solutions tailored to the specific subsystem
requirements.  Our long experience with PCI Express connectivity
products enables PLX to deliver reliable devices that operate under non-ideal
real-world system environments.





PLX is
building on our broad, general purpose interconnect success, and in particular
our success in enterprise storage, by focusing on a rapidly growing vertical
market: Consumer/SOHO storage.  On January 2, 2009, we completed the
acquisition of Oxford Semiconductor, Inc. (Oxford), a leading supplier of
semiconductor components for the consumer and SOHO markets. Oxford has brought
to market several generations of leadership products that allow storage
customers to attach their disk subsystems directly to a computer through USB
direct-attached storage (DAS), or to attach them through local area
network-attached storage (NAS).  We identified the shift from parallel
to serial hard disk connectivity early, and benefited from this trend to be
become the leader in high performance consumer/SOHO storage
connectivity.   Our products provide a rich variety of
connectivity options, including USB, SATA, eSATA, FireWire, and Ethernet, and
offer capabilities such as RAID and data encryption at industry leading
performance levels.





PLX
offers a complete solution consisting of semiconductor devices, software
development kits, hardware design kits, operating system ports, and firmware
solutions that enable added-value features in our products.  We
differentiate our products by offering higher performance and lower power, and
by enabling a richer customer experience based on proprietary features that
enable system-level customer advantages, and by providing capabilities that
enable a customer to get to market more quickly.





We
utilize a “fabless” semiconductor business model whereby we purchase wafers or
packaged and tested semiconductor devices from independent manufacturing
foundries.  The advantage of this approach, in our opinion, allows us
to focus on defining, developing and marketing our products and eliminates the
need for us to invest large amounts of capital in manufacturing facilities and
work-in-process inventory.





We rely
on a combination of direct sales personnel, distributors and manufacturers’
representatives throughout the world to sell a significant portion of our
products.  We pay manufacturers’ representatives a commission on sales
while we sell products to distributors at a discount from the selling
price.





The time
period between initial customer evaluation and design completion can range from
six to twelve months or more.  Furthermore, there is typically an
additional six to twelve month or greater period after design completion before
a customer orders volume production of our products.  Due to the
variability and length of these design cycles and variable demand from
customers, we may experience significant fluctuations in new orders from month
to month.  In addition, we typically make inventory purchases prior to
receiving customer orders.  Consequently, if anticipated sales and
shipments in any quarter do not occur when expected, expenses and inventory
levels could be disproportionately high, and our results for that quarter and
potentially future quarters would be materially and adversely
affected.





Our
long-term success will depend on our ability to successfully introduce new
products.  While new products typically generate little or no revenues
during the first twelve months following their introduction, our revenues in
subsequent periods depend upon these new products.  Due to the lengthy
sales cycle and additional time before our customers request volume production,
significant revenues from our new products typically occur twelve to twenty-four
months after product introduction.  As a result, revenues from newly
introduced products have, in the past, produced a small percentage of our total
revenues in the year the product was introduced.  See –“Our Lengthy
Sales Cycle Can Result in Uncertainty and Delays with Regard to Our Expected
Revenues” in Item 1A, Risk Factors, in Part II of this report on Form
10-Q.

Net
revenues consist of product revenues generated principally by sales of our
semiconductor devices.  Net revenues for the three months ended
September 30, 2009 were $21.6 million, an increase of 3.7% from $20.8 million
for the same period in 2008. The increase was due to revenues generated from the
Storage and Connectivity products acquired as part of the Oxford acquisition,
largely offset by lower sales of our PCI Express and Connectivity products as a
result of a decline in enterprise and consumer spending, which resulted from the
weakened global economy and economic uncertainty.





Net
revenues for the nine months ended September 30, 2009 were $56.2 million, a
decrease of 16.0% from $66.9 million for the same period in 2008. The decrease
was due to lower sales as a result of a decline in enterprise and consumer
spending, which resulted from the weakened global economy and economic
uncertainty, largely offset by revenues generated from the Storage and
Connectivity products acquired as part of the Oxford acquisition.





There
were no direct end customers that accounted for more than 10% of net revenues.
Sales to the following distributors accounted for 10% or more of net
revenues:

In the
fourth quarter of 2008 and the first quarter of 2009, we experienced a broad
decrease in order rates across most product lines, markets and end customers,
and as we have seen improved market conditions in the second and third quarter
of 2009, we expect sales to continue to modestly expand in the fourth quarter of
2009 compared to the third quarter of 2009. Future demand for our products is
uncertain and is highly dependant on general economic conditions and the demand
for products that contain our chips. Customer demand for semiconductors can
change quickly and unexpectedly.  Our revenue levels have been highly
dependent on the amount of new orders that are received for products to be
delivered to the customer within the same quarter, also called “turns fill”
orders.  Because of the long cycle time to build our products and our lack
of visibility into demand when turns fill orders are high, it is difficult to
predict which products to build to match future demand.  We believe the
current high turns fill requirements will continue indefinitely.  The
high turns fill orders pattern, together with the uncertainty of product mix and
pricing, makes it difficult to predict future levels of sales and profitability
and may require us to carry higher levels of inventory.

Gross
Margin





Gross
margin represents net revenues less the cost of revenues.  Cost of
revenues includes the cost of (1) purchasing semiconductor devices or wafers
from our independent foundries, (2) package, assembly and test services from our
independent foundries, assembly contractors and test contractors and (3) our
operating costs associated with the procurement, storage, and shipment of
products as allocated to production.

Gross
profit for the three months ended September 30, 2009 decreased by 0.2% compared
to the same period in 2008. The decrease in absolute dollars and as a percentage
was primarily due to the lower margins of the storage products acquired in the
Oxford acquisition as well as overall product mix.





Gross
profit for the nine months ended September 30, 2009 decreased by 21.8% compared
to the same period in 2008. The decrease in absolute dollars was primarily due
to the overall decrease of product shipments, while the decrease as a percentage
was primarily due to lower margins of the storage products acquired in the
Oxford acquisition as well as overall product mix.





Future
gross profit and gross margin are highly dependent on the product and customer
mix, provisions and sales of excess or obsolete inventory, the position of our
products in their respective life cycles and specific manufacturing
costs.  Accordingly, we are not able to predict future gross profit
levels or gross margins with certainty.





Research
and Development Expenses





Research
and development (“R&D”) expenses consist primarily of tape-out costs at our
independent foundries, salaries and related costs, including share-based
compensation and expenses for outside engineering consultants.

R&D
expenses increased by $1.6 million or 25.8% in the three months ended September
30, 2009 compared to the same period in 2008. The increase in R&D in
absolute dollars and as a percentage of revenue is due primarily to increases in
R&D spending on compensation and benefit expenses of $0.9 million and
engineering tools of $0.7 million associated with the acquisition of
Oxford.





R&D
expenses increased by $3.7 million or 18.4% in the nine months ended September
30, 2009 compared to the same period in 2008. The increase in R&D in
absolute dollars and as a percentage of revenue is due primarily to increases in
R&D spending on compensation and benefit expenses of $2.1 million,
engineering tools of $1.8 million and office lease expenses of $0.4 million
associated with the acquisition of Oxford, partially offset by decreases in
consulting expenses of $0.6 million due to a decrease in the number of projects
taped-out and cost control efforts.





We
believe continued spending on research and development to develop new products
is critical to our success. We anticipate that R&D expenses over time will
fluctuate due to the timing of projects and tape-out related
activities.

Selling,
General and Administrative Expenses





Selling,
general and administrative (“SG&A”) expenses consist primarily of salaries
and related costs, including share-based compensation, commissions to
manufactures’ representatives and professional fees, as well as trade show and
other promotional expenses.

During
the nine months ended September 30, 2009 we recorded $2.9 million in acquisition
related costs associated with the January 2, 2009 acquisition of Oxford. Deal
costs related primarily to outside legal and accounting costs. Severance costs
were the result of layoffs due to the redundancy issue that arose as a result of
the acquisition and the downsizing of our Singapore R&D facility. In
addition, we assumed a building lease in Milpitas, California which was vacated
upon the acquisition.  As a result, we took a lease commitment charge
on the operating lease in the first quarter of 2009. See Note 10 of the
condensed consolidated financial statements for additional
information.





Amortization
of Acquired Intangible Assets





Amortization
of acquired intangible assets consists of amortization expense related to
developed core technology, tradename and customer base acquired as a result of
the Oxford acquisition in January 2009 and the developed core technology
acquired in the HiNT Corporation acquisition in May 2003 and NetChip Technology,
Inc. acquisition in May 2004.

Amortization
of acquired intangible increased by $0.7 million or 469.3% in the three months
ended September 30, 2009 compared to the same period in 2008. The 2008
amortization expense related to intangibles acquired in our prior acquisitions
of HiNT and NetChip. In December 2008 we determined that these assets were
impaired and the remaining carrying value of $0.8 million was written off. The
amortization expense in 2009 relates to the developed core technology, tradename
and customer base acquired as a result of the acquisition of Oxford. See Note 8

Interest
income reflects interest earned on cash, cash equivalents and short-term and
long-term investment balances. Interest income for the three months ended
September 30, 2009 decreased by $0.2 million or 61.2%, compared to the same
period in 2008. The decrease was primarily due to lower cash and investment
balances and decreased interest rates.





Interest
income for the nine months ended September 30, 2009 decreased by $0.6 million or
54.8%, compared to the same period in 2008. The decrease was primarily due to
lower cash and investment balances and interest rate fluctuations.





Interest
expense of for the three months ended September 30, 2009 of $30,000 consisted of
interest recorded on our capital lease obligations. We did not record interest
expense for the same period in 2008.





Interest
expense of for the nine months ended September 30, 2009 of $0.4 million
primarily consisted of interest recorded on the $14.2 million note associated
with the acquisition of Oxford. This note was converted to 3.4 million shares of
common stock of PLX on May 22, 2009. In addition, there was interest recorded on
our capital lease obligations. We did not record interest expense for the same
period in 2008.





Other
income includes foreign currency translation gains and losses and other
miscellaneous transactions. Other income for the three and nine months ended
September 30, 2009 included $0.1 million loss due to the liquidation of our
subsidiary in the United Kingdom as a result of the acquisition of Oxford and
its subsidiary in the United Kingdom.  Other income may fluctuate
significantly.





Loss
on Fair Value Remeasurement of Contingently Convertible Note
Payable





As a part
of the consideration for the Oxford acquisition, we recorded a liability for the
contingent consideration due which was recorded at fair value as of the
acquisition date. We are required to remeasure the liability to fair value until
the contingency is resolved and record the change in fair value in
earnings.  The fair value of the note payable was based on 3.4 million
shares with a stock price of $1.82, or $6.2 million. As of March 31, 2009, the
closing stock price was $2.17, or $7.4 million. The loss on the fair value of
the note remeasurement is the increase in fair value of the liability of $1.2
million, which was recorded in the first quarter of 2009. As of May 22, 2009,
the date of conversion, the closing stock price was $2.95, or $10.0 million. The
loss on the fair value of the note of $2.7 million was recorded in the second
quarter of 2009. See Note 7 of the condensed consolidated financial statements
for additional information on the contingent consideration
arrangement.

Provision
for Income Taxes





An income
tax benefit of $6,000 has been recorded for the nine month period ended
September 30, 2009, compared to provision of $0.4 million for the same period in
2008.  Income tax benefit for the nine months ended September 30, 2009
is a result of applying the estimated annual effective tax rate to cumulative
loss before taxes adjusted for certain discrete items which are fully recognized
in the period they occur.  For the same period in 2008, the income tax
expense was calculated on a year-to-date discrete basis due to the uncertainty
of fourth quarter operating estimates and large variability to the annual
effective rate based on small changes to ordinary income for the
year.





We have
determined that negative evidence supports the need for a full valuation
allowance against our net deferred tax assets at this time. We will maintain a
full valuation allowance until sufficient positive evidence exists to support a
reversal of the valuation allowance.





As of
September 30, 2009, we have unrecognized tax benefits of approximately $2.5
million of which none, if recognized, would result in a reduction of our
effective tax rate.  There were no material changes in the amount of
unrecognized tax benefits during the nine months ended September 30,
2009.  Future changes in the balance of unrecognized tax benefits will
have no impact on the effective tax rate as they are subject to a full valuation
allowance. We do not expect that the amount of our unrecognized tax benefits
will significantly change within the next twelve months.





We are
subject to taxation in the United States and various states and foreign
jurisdictions.  The tax years 1998 through 2008 remain open to
examination by the federal and most state tax authorities due to certain
acquired net operating loss and overall credit carryforward
positions.

We invest
excess cash predominantly in debt instruments that are highly liquid, of
high-quality investment grade, and predominantly have maturities of less than
one year with the intent to make such funds readily available for operating
purposes. As of September 30, 2009 cash, cash equivalents, short and long-term
marketable securities were $38.5 million, a decrease of $8.6 million from $47.1
million at December 31, 2008.





Cash
provided by (used in) operating activities primarily consists of net income
(loss) adjusted for certain non-cash items including depreciation, amortization,
share-based compensation expense, impairments, fair value remeasurements,
provisions for excess and obsolete inventories, changes in pre-acquisition
deferred tax balances, other non-cash items, and the effect of changes in
working capital and other activities. Cash used in operating activities for the
nine months ended September 30, 2009 of $10.5 million consisted primarily
of a net loss of $21.4 million adjusted for non-cash items of $11.5
million, decreases in accrued compensation and benefits of $1.5 million,
accounts payable of $0.5 million and other accrued expenses and liabilities of
$0.5 million and increases in accounts receivable of $0.7 million and other
assets of $0.5 million, partially offset by decreases in inventory of $1.2
million and other current assets of $1.8 million due to the amortization of
software and IP licenses and a 2008 tax refund received for R&D activities
in the United Kingdom. Cash provided by operating activities for the nine months
ended September 30, 2008 of $4.8 million consisted primarily of net income
of $1.8 million adjusted for non-cash items of $5.0 million and a decrease
in accounts receivable of $0.7 million, partially offset by increases in current
assets of $0.8 million and other assets of $0.7 million due to an increase in
software and IP licenses and a decrease in accounts payable of $0.9
million.





Cash
provided by investing activities for the nine months ended September 30, 2009 of
$18.5 million was primarily due to the sales and maturities of investments
(net of purchases of investments) of $14.9 million and cash acquired
through the acquisition of Oxford of $4.4 million, partially offset by capital
expenditures of $0.8 million. Cash used in investing activities for the nine
months ended September 30, 2008 of $2.7 million was due to purchases of
marketable securities (net of sales and maturities of investments) of $1.1
million and capital expenditures of $1.6 million. Capital expenditures have
generally been comprised of purchases of engineering equipment, computer
hardware, software, server equipment and furniture and fixtures.





25





Cash used
in financing activities for the nine months ended September 30, 2009 of $1.4
million was due to the payments made to employees associated with the tender
offer of $0.9 million and on capital lease obligations of $0.5 million. Cash
used in financing activities for the nine months ended September 30, 2008 of
$5.6 million was due to common stock repurchases of $6.5 million, partially
offset by the proceeds from the exercise of stock options of $0.8
million.





The
negative effect of exchange rates on cash and cash equivalents for the nine
months ended September 30, 2009 and 2008 was due to the weakening of the U.S.
dollar against other foreign currencies.





As of
September 30, 2009, we had the following significant contractual obligations and

We
believe that our existing resources, together with cash generated from our
operations will be sufficient to meet our capital requirements for at least the
next twelve months.  Our future capital requirements will depend on
many factors, including the inventory levels we maintain, the level of
investment we make in new technologies and improvements to existing technologies
and the levels of monthly expenses required to launch new
products.  From time to time, we may also evaluate potential
acquisitions and equity investments complementary to our technologies and market
strategies.  To the extent that existing resources and future earnings
are insufficient to fund our future activities, we may need to raise additional
funds through public or private financings.  Additional funds may not
be available or, if available, we may not be able to obtain them on terms
favorable to us and our stockholders.





Critical
Accounting Policies





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,
revenues and expenses and related disclosures of contingent assets and
liabilities in the condensed consolidated financial statements and accompanying
notes. The U.S. Securities and Exchange Commission (“SEC”) has defined a
company’s critical accounting policies as the ones that are most important to
the portrayal of the company’s financial condition and results of operations,
and which require the company to make its most difficult and subjective
judgments, often as a result of the need to make estimates of matters that are
inherently uncertain.  Based on this definition, we have identified
the critical accounting policies and judgments addressed below.  We
also have other key accounting policies which involve the use of estimates,
judgments and assumptions that are significant to understanding our results.
Although we believe that our estimates, assumptions and judgments are
reasonable, they are based upon information presently
available.  Actual results may differ significantly from these
estimates under different assumptions, judgments or conditions.





Revenue
Recognition





We
recognize revenue when persuasive evidence of an arrangement exists, delivery or
customer acceptance, where applicable, has occurred, the fee is fixed or
determinable, and collection is reasonably assured.





Revenue
from product sales to direct customers and distributors is recognized upon
shipment and transfer of risk of loss, if we believe collection is reasonably
assured and all other revenue recognition criteria are met. We assess the
probability of collection based on a number of factors, including past
transaction history and the customer’s creditworthiness.  At the end of
each reporting period, the sufficiency of allowances for doubtful accounts is
assessed based on the age of the receivable and the individual customer’s
creditworthiness.





26





As of
September 30, 2009, we offer pricing protection to two distributors whereby the
Company supports the distributor’s resale product margin on certain products
held in the distributor’s inventory. In general, we analyze current requests for
credit in process, also known as ship and debits and inventory at the
distributor to determine the ending sales reserve required for this
program.  We also offer stock rotation rights to two distributors such
that they can return up to a total of 5% of products purchased every six months
in exchange for other PLX products of equal value. In general, we analyze
current stock rotation requests and past experience, which has historically been
insignificant, to determine the ending sales reserve required for this program.
In addition, we have arrangements with a small number of customers offering a
rebate program on various products.  We record rebates as a reduction
of revenue. Reserves are reduced directly from revenue and recorded as a
reduction to accounts receivable.





Inventory
Valuation





We
evaluate the need for potential inventory provisions by considering a
combination of factors, including the life of the product, sales history,
obsolescence, and sales forecasts. Any adverse changes to our future product
demand may result in increased provisions, resulting in decreased gross
margin.  In addition, future sales on any of our previously written
down inventory may result in increased gross margin in the period of
sale.





Allowance
for Doubtful Accounts





We
evaluate the collectibility of our accounts receivable based on length of time
the receivables are past due. Generally, our customers have between thirty to
forty five days to remit payment of invoices. We record reserves for bad debts
against amounts due to reduce the net recognized receivable to the amount we
reasonably believe will be collected.  Once we have exhausted
collection efforts, we will reduce the related accounts receivable against the
allowance established for that receivable. We have certain customers with
individually large amounts due at any given balance sheet date.  Any
unanticipated change in one of those customers’ creditworthiness or other
matters affecting the collectibility of amounts due from such customers could
have a material adverse affect on our results of operations in the period in
which such changes or events occur. Historically, our write-offs have been
insignificant.





Goodwill





Our
methodology for allocating the purchase price related to business acquisitions
is determined through established valuation techniques. Goodwill is measured as
the excess of the cost of the acquisition over the amounts assigned to
identifiable tangible and intangible assets acquired less assumed liabilities.
We have one operating segment and business reporting unit, the sales of
semiconductor devices, and we perform goodwill impairment tests annually during
the fourth quarter and between annual tests if indicators of potential
impairment exist.





Long-lived
Assets





We review
long-lived assets, principally property and equipment and identifiable
intangibles, for impairment whenever events or circumstances indicate that the
carrying amount of assets may not be recoverable. We evaluate recoverability of
assets to be held and used by comparing the carrying amount of an asset to
estimated future net undiscounted cash flows generated by the
asset.  If such assets are considered to be impaired, the impairment
recognized is measured as the amount by which the carrying amount of the assets
exceeds the fair value of the assets.





Share-Based
Compensation





We
estimate the value of employee stock options on the date of grant using the
Black-Scholes model. The determination of fair value of share-based payment
awards on the date of grant using an option-pricing model is affected by our
stock price as well as assumptions regarding a number of highly complex and
subjective variables.  These variables include, but are not limited to
the expected stock price volatility over the term of the awards and the actual
and projected employee stock option exercise behaviors. The expected term of
options granted is derived from historical data on employee exercises and
post-vesting employment termination behavior.  Historically, we
calculated our expected volatility assumption required in the Black-Scholes
model by using a 50/50 blend of historical volatility and market-based
volatility. However, due to the recent lack of available market data to
calculate implied volatility, we began using 100% historical volatility during
the fourth quarter of 2008. We estimate the amount of forfeitures at the time of
grant and revise, if necessary, in subsequent periods if actual forfeitures
differ from those estimates.





27





Taxes





We
account for income taxes using the asset and liability
method.  Deferred taxes are determined based on the differences
between the financial statement and tax bases of assets and liabilities, using
enacted tax rates in effect for the year in which the differences are expected
to reverse.  Valuation allowances are established when necessary to
reduce deferred tax assets to the amounts expected to be realized. As of
September 30, 2009, we carried a valuation allowance for the entire deferred tax
asset as a result of uncertainties regarding the realization of the asset
balance. We will maintain a full valuation allowance against our deferred tax
assets until sufficient positive evidence exists to support a reversal of the
valuation allowance.





Future
taxable income and/or tax planning strategies may eliminate all or a portion of
the need for the valuation allowance. In the event we determine we are able to
realize our deferred tax asset, an adjustment to the valuation allowance may
increase income in the period such determination is made.





ITEM
3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET
RISK





We have
an investment portfolio of fixed income securities, including amounts classified
as cash equivalents, short-term investments and long-term investments of $32.3
million at September 30, 2009.  These securities are subject to
interest rate fluctuations and will decrease in market value if interest rates
increase.





The
primary objective of our investment activities is to preserve principal while at
the same time maximizing yields without significantly increasing
risk.  We invest primarily in high quality, short-term and long-term
debt instruments. A hypothetical 100 basis point increase in interest rates
would result in less than a $2,000 decrease (less than 1%) in the fair value of
our available-for-sale securities.





ITEM
4.  CONTROLS AND PROCEDURES





(a)
Evaluation of disclosure controls and procedures.





Based on
their evaluation as of September 30, 2009, our Chief Executive Officer and Chief
Financial Officer have concluded that our disclosure controls and procedures (as
defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act
of 1934, as amended) were effective to ensure that the information required to
be disclosed by us in this Quarterly Report on Form 10-Q was recorded,
processed, summarized and reported within the time periods specified in the
SEC's rules and instructions for Form 10-Q and that such disclosure
controls and procedures were also effective to ensure that information required
to be disclosed in the reports we file or submit under the Exchange Act is
accumulated and communicated to our management, including our Chief Executive
Officer and Chief Financial Officer, as appropriate to allow timely decisions
regarding required disclosure.





(b) Changes
in internal controls.





There has
been no change in our internal control over financial reporting that occurred
during our most recent fiscal quarter that has materially affected or is
reasonably likely to materially affect our internal control over financial
reporting.

PART
II. OTHER INFORMATION





ITEM
1A.  RISK FACTORS





FACTORS
THAT MAY AFFECT FUTURE OPERATING RESULTS





This
quarterly report on Form 10-Q contains forward-looking statements which involve
risks and uncertainties.  Our actual results could differ materially
from those anticipated by such forward-looking statements as a result of certain
factors, including those set forth below.  The following risk factors
have been updated from those set forth in Item 1A. of Part I of our Annual
Report on Form 10-K for the year ended December 31, 2008, and are restated in
full.





Global
Economic Conditions May Continue to Have an Adverse Effect on Our Businesses and
Results of Operations





The
severe tightening of the credit markets, turmoil in the financial markets, and
weakening global economy are contributing to slowdowns in the industries in
which we operate.  Economic uncertainty exacerbates negative trends in
spending and may cause certain customers to push out, cancel, or refrain from
placing orders, which may reduce revenue. Difficulties in obtaining capital and
deteriorating market conditions may also lead to the inability of some customers
to obtain affordable financing, resulting in lower sales. Customers with
liquidity issues may lead to additional bad debt expense. These conditions may
also similarly affect key suppliers, which could affect their ability to deliver
parts and result in delays in the availability of product.  Further,
these conditions and uncertainty about future economic conditions make it
challenging for us to forecast our operating results, make business decisions,
and identify the risks that may affect our business, financial condition and
results of operations. In addition, we maintain an investment portfolio that is
subject to general credit, liquidity, market and interest rate risks that may be
exacerbated by deteriorating financial market conditions and, as a result, the
value and liquidity of the investment portfolio could be negatively impacted and
lead to impairment.  If the current economic conditions are prolonged
or deteriorate further, or if we are not able to timely and appropriately adapt
to changes resulting from the difficult macroeconomic environment, our business,
financial condition or results of operations may be materially and adversely
affected.





Our
Operating Results May Fluctuate Significantly Due To Factors Which Are Not
Within Our Control





Our
quarterly operating results have fluctuated significantly in the past and are
expected to fluctuate significantly in the future based on a number of factors,
many of which are not under our control.  Our operating expenses,
which include product development costs and selling, general and administrative
expenses, are relatively fixed in the short-term.  If our revenues are
lower than we expect because we sell fewer semiconductor devices, delay the
release of new products or the announcement of new features, or for other
reasons, we may not be able to quickly reduce our spending in
response.





Other
      circumstances that can affect our operating results
    include:




·
            the
      timing of significant orders, order cancellations and
      reschedulings;


·
            the
      loss of one or more significant
customers;


·
            introduction
      of products and technologies by our
competitors;


·
            the
      availability of production capacity at the fabrication facilities that
      manufacture our products;


·
            our
      significant customers could lose market share that may affect our
      business;


·
            integration
      of our product functionality into our customers’
  products;


·
            our
      ability to develop, introduce and market new products and technologies on
      a timely basis;


·
            unexpected
      issues that may arise with devices in
  production;


·
            shifts
      in our product mix toward lower margin
products;


·
            changes
      in our pricing policies or those of our competitors or suppliers,
      including decreases in unit average selling prices of our
      products;


·
            the
      availability and cost of materials to our
  suppliers;


·
            general
      macro economic conditions; and


·
            political
      climate.





These
factors are difficult to forecast, and these or other factors could adversely
affect our business.  Any shortfall in our revenues would have a
direct impact on our business.  In addition, fluctuations in our
quarterly results could adversely affect the market price of our common stock in
a manner unrelated to our long-term operating performance.

The
Cyclical Nature Of The Semiconductor Industry May Lead To Significant Variances
In The Demand For Our Products





In the
past, the semiconductor industry has been characterized by significant downturns
and wide fluctuations in supply and demand.  Also, during this time,
the industry has experienced significant fluctuations in anticipation of changes
in general economic conditions.  This cyclicality has led to
significant variances in product demand and production capacity.  It
has also accelerated erosion of average selling prices per unit on some of our
products.  We may experience periodic fluctuations in our future
financial results because of industry-wide conditions.





Because
A Substantial Portion Of Our Net Sales Is Generated By A Small Number Of Large
Customers, If Any Of These Customers Delays Or Reduces Its Orders, Our Net
Revenues And Earnings Will Be Harmed





Historically,
a relatively small number of customers have accounted for a significant portion
of our net revenues in any particular period.  See Note 12 of the
condensed consolidated financial statements for customer
concentrations.





We have
no long-term volume purchase commitments from any of our significant customers.
We cannot be certain that our current customers will continue to place orders
with us, that orders by existing customers will continue at the levels of
previous periods or that we will be able to obtain orders from new customers. In
addition, some of our customers supply products to end-market purchasers and any
of these end-market purchasers could choose to reduce or eliminate orders for
our customers' products. This would in turn lower our customers' orders for our
products.





We
anticipate that sales of our products to a relatively small number of customers
will continue to account for a significant portion of our net
sales.  Due to these factors, the following have in the past and may
in the future reduce our net sales or earnings:





·
            the
      reduction, delay or cancellation of orders from one or more of our
      significant customers;


·
            the
      selection of competing products or in-house design by one or more of our
      current customers;


·
            the
      loss of one or more of our current customers;
or


·
            a
      failure of one or more of our current customers to pay our
      invoices.





Intense
Competition In The Markets In Which We Operate May Reduce The Demand For Or
Prices Of Our Products





Competition
in the semiconductor industry is intense.  If our main target market,
the microprocessor-based systems market, continues to grow, the number of
competitors may increase significantly.  In addition, new
semiconductor technology may lead to new products that can perform similar
functions as our products.  Some of our competitors and other
semiconductor companies may develop and introduce products that integrate into a
single semiconductor device the functions performed by our semiconductor
devices.  This would eliminate the need for our products in some
applications.





In
addition, competition in our markets comes from companies of various sizes, many
of which are significantly larger and have greater financial and other resources
than we do and thus can better withstand adverse economic or market conditions.
Therefore, we cannot assure you that we will be able to compete successfully in
the future against existing or new competitors, and increased competition may
adversely affect our business.  See “Business -- Products,” and “--
Competition” in Part I of Item I of our Form 10-K for the year ended December
31, 2008.





Our
Independent Manufacturers May Not Be Able To Meet Our Manufacturing
Requirements





We do not
manufacture any of our semiconductor devices.  Therefore, we are
referred to in the semiconductor industry as a “fabless” producer of
semiconductors. Consequently, we depend upon third party manufacturers to
produce semiconductors that meet our specifications.  We currently
have third party manufacturers located in China, Japan, Korea, Malaysia,
Singapore and Taiwan, that can produce semiconductors which meet our
needs.  However, as the semiconductor industry continues to progress
towards smaller manufacturing and design geometries, the complexities of
producing semiconductors will increase.  Decreasing geometries may
introduce new problems and delays that may affect product development and
deliveries.  Due to the nature of the semiconductor industry and our
status as a fabless semiconductor company, we could encounter
fabrication-related problems that may affect the availability of our
semiconductor devices, delay our shipments or may increase our
costs.





30





Only a
small number of our semiconductor devices are currently manufactured by more
than one supplier.  We place our orders on a purchase order basis and
do not have a long term purchase agreement with any of our existing
suppliers.  In the event that the supplier of a semiconductor device
was unable or unwilling to continue to manufacture our products in the required
volume, we would have to identify and qualify a substitute
supplier.  Introducing new products or transferring existing products
to a new third party manufacturer or process may result in unforeseen device
specification and operating problems.  These problems may affect
product shipments and may be costly to correct.  Silicon fabrication
capacity may also change, or the costs per silicon wafer may
increase.  Manufacturing-related problems may have a material adverse
effect on our business.





Lower
Demand For Our Customers’ Products Will Result In Lower Demand For Our
Products





Demand
for our products depends in large part on the development and expansion of the
high-performance microprocessor-based systems markets including networking and
telecommunications, enterprise and customer storage, imaging and industrial
applications.  The size and rate of growth of these
microprocessor-based systems markets may in the future fluctuate significantly
based on numerous factors.  These factors include the adoption of
alternative technologies, capital spending levels and general economic
conditions. Demand for products that incorporate high-performance
microprocessor-based systems may not grow.





Our
Lengthy Sales Cycle Can Result In Uncertainty And Delays With Regard To Our
Expected Revenues





Our
customers typically perform numerous tests and extensively evaluate our products
before incorporating them into their systems.  The time required for
test, evaluation and design of our products into a customer’s equipment can
range from six to twelve months or more.  It can take an additional
six to twelve months or more before a customer commences volume shipments of
equipment that incorporates our products.  Because of this lengthy
sales cycle, we may experience a delay between the time when we increase
expenses for research and development and sales and marketing efforts and the
time when we generate higher revenues, if any, from these
expenditures.





In
addition, the delays inherent in our lengthy sales cycle raise additional risks
of customer decisions to cancel or change product plans.  When we
achieve a design win, there can be no assurance that the customer will
ultimately ship products incorporating our products.  Our business
could be materially adversely affected if a significant customer curtails,
reduces or delays orders during our sales cycle or chooses not to release
products incorporating our products.





Failure
To Have Our Products Designed Into The Products Of Electronic Equipment
Manufacturers Will Result In Reduced Sales





Our
future success depends on electronic equipment manufacturers that design our
semiconductor devices into their systems.  We must anticipate market
trends and the price, performance and functionality requirements of current and
potential future electronic equipment manufacturers and must successfully
develop and manufacture products that meet these requirements.  In
addition, we must meet the timing requirements of these electronic equipment
manufacturers and must make products available to them in sufficient
quantities.  These electronic equipment manufacturers could develop
products that provide the same or similar functionality as one or more of our
products and render these products obsolete in their applications.





We do not
have purchase agreements with our customers that contain minimum purchase
requirements.  Instead, electronic equipment manufacturers purchase
our products pursuant to short-term purchase orders that may be canceled without
charge. We believe that in order to obtain broad penetration in the markets for
our products, we must maintain and cultivate relationships, directly or through
our distributors, with electronic equipment manufacturers that are leaders in
the embedded systems markets.  Accordingly, we will incur significant
expenditures in order to build relationships with electronic equipment
manufacturers prior to volume sales of new products. If we fail to develop
relationships with additional electronic equipment manufacturers to have our
products designed into new microprocessor-based systems or to develop sufficient
new products to replace products that have become obsolete, our business would
be materially adversely affected.





Defects
In Our Products Could Increase Our Costs And Delay Our Product
Shipments





Our
products are complex. While we test our products, these products may still have
errors, defects or bugs that we find only after commercial production has begun.
We have experienced errors, defects and bugs in the past in connection with new
products.





31





Our
customers may not purchase our products if the products have reliability,
quality or compatibility problems. This delay in acceptance could make it more
difficult to retain our existing customers and to attract new
customers.  Moreover, product errors, defects or bugs could result in
additional development costs, diversion of technical and other resources from
our other development efforts, claims by our customers or others against us, or
the loss of credibility with our current and prospective customers. In the past,
the additional time required to correct defects has caused delays in product
shipments and resulted in lower revenues. We may have to spend significant
amounts of capital and resources to address and fix problems in new
products.





We must
continuously develop our products using new process technology with smaller
geometries to remain competitive on a cost and performance
basis.  Migrating to new technologies is a challenging task requiring
new design skills, methods and tools and is difficult to achieve.





Failure
Of Our Products To Gain Market Acceptance Would Adversely Affect Our Financial
Condition





We
believe that our growth prospects depend upon our ability to gain customer
acceptance of our products and technology.  Market acceptance of
products depends upon numerous factors, including compatibility with other
products, adoption of relevant interconnect standards, perceived advantages over
competing products and the level of customer service available to support such
products.  There can be no assurance that growth in sales of new
products will continue or that we will be successful in obtaining broad market
acceptance of our products and technology.





We expect
to spend a significant amount of time and resources to develop new products and
refine existing products. In light of the long product development cycles
inherent in our industry, these expenditures will be made well in advance of the
prospect of deriving revenues from the sale of any new products. Our ability to
commercially introduce and successfully market any new products is subject to a
wide variety of challenges during this development cycle, including start-up
bugs, design defects and other matters that could delay introduction of these
products to the marketplace. In addition, since our customers are not obligated
by long-term contracts to purchase our products, our anticipated product orders
may not materialize, or orders that do materialize may be cancelled. As a
result, if we do not achieve market acceptance of new products, we may not be
able to realize sufficient sales of our products in order to recoup research and
development expenditures. The failure of any of our new products to achieve
market acceptance would harm our business, financial condition, results of
operation and cash flows.





A
Large Portion Of Our Revenues Is Derived From Sales To Third-Party Distributors
Who May Terminate Their Relationships With Us At Any Time





We depend
on distributors to sell a significant portion of our products. For the nine
months ended September 30, 2009 and 2008, sales through distributors accounted
for approximately 88% and 78%, respectively, of our net revenues. Some of our
distributors also market and sell competing products.  Distributors
may terminate their relationships with us at any time.  Our future
performance will depend in part on our ability to attract additional
distributors that will be able to market and support our products effectively,
especially in markets in which we have not previously distributed our products.
We may lose one or more of our current distributors or may not be able to
recruit additional or replacement distributors. The loss of one or more of our
major distributors could have a material adverse effect on our business, as we
may not be successful in servicing our customers directly or through
manufacturers’ representatives.





The
Demand For Our Products Depends Upon Our Ability To Support Evolving Industry
Standards





A
majority of our revenues are derived from sales of products, which rely on the
PCI Express, PCI, PCI-X, SATA, Ethernet, Firewire and USB
standards.  If markets move away from these standards and begin using
new standards, we may not be able to successfully design and manufacture new
products that use these new standards.  There is also the risk that
new products we develop in response to new standards may not be accepted in the
market.  In addition, these standards are continuously evolving, and
we may not be able to modify our products to address new
specifications.  Any of these events would have a material adverse
effect on our business.





32





We
Must Make Significant Research And Development Expenditures Prior To Generating
Revenues From Products





To
establish market acceptance of a new semiconductor device, we must dedicate
significant resources to research and development, production and sales and
marketing.  We incur substantial costs in developing, manufacturing
and selling a new product, which often significantly precede meaningful revenues
from the sale of this product.  Consequently, new products can require
significant time and investment to achieve profitability.  Investors
should understand that our efforts to introduce new semiconductor devices or
other products or services may not be successful or profitable.  In
addition, products or technologies developed by others may render our products
or technologies obsolete or noncompetitive.





We record
as expenses the costs related to the development of new semiconductor devices
and other products as these expenses are incurred.  As a result, our
profitability from quarter to quarter and from year to year may be adversely
affected by the number and timing of our new product launches in any period and
the level of acceptance gained by these products.





We
Could Lose Key Personnel Due To Competitive Market Conditions And
Attrition





Our
success depends to a significant extent upon our senior management and key
technical and sales personnel.  The loss of one or more of these
employees could have a material adverse effect on our business.  We do
not have employment contracts with any of our executive officers.





Our
success also depends on our ability to attract and retain qualified technical,
sales and marketing, customer support, financial and accounting, and managerial
personnel.  Competition for such personnel in the semiconductor
industry is intense, and we may not be able to retain our key personnel or to
attract, assimilate or retain other highly qualified personnel in the
future.  In addition, we may lose key personnel due to attrition,
including health, family and other reasons.  We have experienced, and
may continue to experience, difficulty in hiring and retaining candidates with
appropriate qualifications.  If we do not succeed in hiring and
retaining candidates with appropriate qualifications, our business could be
materially adversely affected.





The
Successful Marketing And Sales Of Our Products Depend Upon Our Third Party
Relationships, Which Are Not Supported By Written Agreements





When
marketing and selling our semiconductor devices, we believe we enjoy a
competitive advantage based on the availability of development tools offered by
third parties.  These development tools are used principally for the
design of other parts of the microprocessor-based system but also work with our
products.  We will lose this advantage if these third party tool
vendors cease to provide these tools for existing products or do not offer them
for our future products.  This event could have a material adverse
effect on our business.  We have no written agreements with these
third parties, and these parties could choose to stop providing these tools at
any time.





Our
Limited Ability To Protect Our Intellectual Property And Proprietary Rights
Could Adversely Affect Our Competitive Position





Our
future success and competitive position depend upon our ability to obtain and
maintain proprietary technology used in our principal
products.  Currently, we have limited protection of our intellectual
property in the form of patents and rely instead on trade secret
protection.  Our existing or future patents may be invalidated,
circumvented, challenged or licensed to others.  The rights granted
there under may not provide competitive advantages to us.  In
addition, our future patent applications may not be issued with the scope of the
claims sought by us, if at all.  Furthermore, others may develop
technologies that are similar or superior to our technology, duplicate our
technology or design around the patents owned or licensed by us.  In
addition, effective patent, trademark, copyright and trade secret protection may
be unavailable or limited in foreign countries where we may need
protection.  We cannot be sure that steps taken by us to protect our
technology will prevent misappropriation of the technology.





We may
from time to time receive notifications of claims that we may be infringing
patents or other intellectual property rights owned by third
parties.  While there is currently no intellectual property litigation
pending against us, litigation could result in significant expenses to us and
adversely affect sales of the challenged product or technology.  This
litigation could also divert the efforts of our technical and management
personnel, whether or not the litigation is determined in our
favor.  In addition, we may not be able to develop or acquire
non-infringing technology or procure licenses to the infringing technology under
reasonable terms.  This could require expenditures by us of
substantial time and other resources.  Any of these developments would
have a material adverse effect on our business.





33





Acquisitions
Could Adversely Affect our Financial Condition and Could Expose Us to
Unanticipated Liabilities





As part
of our business strategy, we expect to continue to review acquisition prospects
that would complement our existing product offerings, improve market coverage or
enhance our technological capabilities.  The Oxford acquisition, as
well as potential future acquisitions, could result in any or all of the
following:





·
            potentially
      dilutive issuances of equity
securities;


·
            large
      acquisition-related write-offs;


·
            potential
      patent and trademark infringement claims against the acquired
      company;


·
            the
      incurrence of debt and contingent liabilities or amortization expenses
      related to other intangible assets;


·
            difficulties
      in the assimilation of operations, personnel, technologies, products and
      the information systems of the acquired
  companies;


·
            the
      incurrence of additional operating losses and expenses of Oxford or other
      potential companies we may acquire;


·
            possible
      delay or failure to achieve expected
synergies;


·
            diversion
      of management’s attention from other business
  concerns;


·
            risks
      of entering geographic and business markets in which we have no or limited
      prior experience; and


·
            potential
      loss of key employees.





Because
We Sell Our Products To Customers Outside Of The United States And Because Our
Products Are Incorporated With Products Of Others That Are Sold Outside Of The
United States We Face Foreign Business, Political And Economic
Risks





Sales
outside of the United States accounted for approximately 85% of our revenues for
the nine months ended September 30, 2009.  In 2008 and 2007, sales
outside of the United States accounted for approximately 77% and 71% of our
revenues, respectively.  Sales outside of the United States may
fluctuate in future periods and may continue to account for a large portion of
our revenues.  In addition, equipment manufacturers who incorporate
our products into their products sell their products outside of the United
States, thereby exposing us indirectly to foreign risks.  Further,
most of our semiconductor products are manufactured outside of the United
States.  Accordingly, we are subject to international risks,
including:





·
            difficulties
      in managing distributors;


·
            difficulties
      in staffing and managing foreign subsidiary and branch
      operations;


·
            political
      and economic instability;


·
            foreign
      currency exchange fluctuations;


·
            difficulties
      in accounts receivable collections;


·
            potentially
      adverse tax consequences;


·
            timing
      and availability of export
licenses;


·
            changes
      in regulatory requirements, tariffs and other
  barriers;


·
            difficulties
      in obtaining governmental approvals for telecommunications and other
      products; and


·
            the
      burden of complying with complex foreign laws and
  treaties.





Because
sales of our products have been denominated to date exclusively in United States
dollars, increases in the value of the United States dollar will increase the
price of our products so that they become relatively more expensive to customers
in the local currency of a particular country, which could lead to a reduction
in sales and profitability in that country.





34





We
May Be Required To Record A Significant Charge To Earnings If Our Goodwill Or
Amortizable Intangible Assets Become Impaired





Under
generally accepted accounting principles, we review our amortizable intangible
and long lived assets for impairment when events or changes in circumstances
indicate the carrying value may not be recoverable. Goodwill is tested for
impairment annually, during the fourth quarter and between annual tests in
certain circumstances.  Factors that may be considered a change in
circumstances, indicating that the carrying value of our goodwill, amortizable
intangible assets or other long lived assets may not be recoverable, include a
persistent decline in stock price and market capitalization, reduced future cash
flow estimates, and slower growth rates in our industry. We may be required to
record a significant charge in our financial statements during the period in
which any additional impairment of our goodwill, amortizable intangible assets
or other long lived assets is determined, which would adversely impact our
results of operations.





Our
Principal Stockholders Have Significant Voting Power And May Take Actions That
May Not Be In The Best Interests Of Our Other Stockholders





Our
executive officers, directors and other principal stockholders, in the
aggregate, beneficially own a substantial amount of our outstanding common
stock. Although these stockholders do not have majority control, they currently
have, and likely will continue to have, significant influence with respect to
the election of our directors and approval or disapproval of our significant
corporate actions.  This influence over our affairs might be adverse
to the interests of other stockholders.  In addition, the voting power
of these stockholders could have the effect of delaying or preventing a change
in control of PLX.





The
Anti-Takeover Provisions In Our Certificate of Incorporation Could Adversely
Affect The Rights Of The Holders Of Our Common Stock





Anti-takeover
provisions of Delaware law and our Certificate of Incorporation may make a
change in control of PLX more difficult, even if a change in control would be
beneficial to the stockholders.  These provisions may allow the Board
of Directors to prevent changes in the management and control of
PLX.





As part
of our anti-takeover devices, our Board of Directors has the ability to
determine the terms of preferred stock and issue preferred stock without the
approval of the holders of the common stock.  Our Certificate of
Incorporation allows the issuance of up to 5,000,000 shares of preferred
stock.  There are no shares of preferred stock
outstanding.  However, because the rights and preferences of any
series of preferred stock may be set by the Board of Directors in its sole
discretion without approval of the holders of the common stock, the rights and
preferences of this preferred stock may be superior to those of the common
stock.  Accordingly, the rights of the holders of common stock may be
adversely affected.  Consistent with Delaware law, our Board of
Directors may adopt additional anti-takeover measures in the
future.





ITEM
2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS





In
September 2002, our Board of Directors authorized the repurchase of up
to 2,000,000 shares of common stock.  In July 2008, our Board of
Directors authorized an additional 2,000,000 shares under the repurchase
program. At the discretion of the management, we can repurchase the shares from
time to time in the open market or in privately negotiated transactions. 
Approximately 774,000 shares were repurchased for approximately $1.9 million in
cash in 2002 and 2003. We did not repurchase any additional shares from January
1, 2004 through December 31, 2007. In 2008 we repurchased 956,000 shares for
approximately $6.5 million. We did not repurchase any additional shares during
the nine months ended September 30, 2009.
