Note 1 — The Company and Summary of Significant Accounting Policies
Energy Recovery, Inc. (the “Company”, “Energy Recovery”, “we”, “our”, or “us”) designs, develops, manufactures, and sells energy recovery devices that transform untapped energy into reusable energy from industrial fluid flows and pressure cycles. Our products are marketed and sold in fluid flow markets, such as desalination and oil and gas, under the trademarks ERI®, PX®, Pressure Exchanger®, PX Pressure Exchanger®, IsoBoost™, IsoGen™, and IsoPro™. Our products are developed and manufactured in the United States of America (“U.S.”) at our headquarters in San Leandro, California. We also have sales offices in Madrid, Spain; Dubai, United Arab Emirates; and Shanghai, Peoples Republic of China.
Use of Estimates
The preparation of condensed consolidated financial statements in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”) requires our management to make judgments, assumptions, and estimates that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Our more significant estimates and judgments that we believe are the most critical to aid in fully understanding and evaluating our reported financial results are revenue recognition; allowance for doubtful accounts; allowance for product warranty; valuation of stock options; valuation and impairment of goodwill, long-lived assets, and acquired intangible assets; useful lives for depreciation and amortization; valuation adjustments for excess and obsolete inventory; deferred taxes and valuation allowances on deferred tax assets; and evaluation and measurement of contingencies, including contingent consideration. Actual results could differ materially from those estimates.
Basis of Presentation
The condensed consolidated financial statements include the accounts of Energy Recovery, Inc. and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.
The accompanying condensed consolidated financial statements have been prepared by us, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. The December 31, 2013 condensed consolidated balance sheet was derived from audited financial statements, and may not include all disclosures required by U.S. GAAP; however, we believe that the disclosures are adequate to make the information presented not misleading. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto for the fiscal year ended December 31, 2013 included in our Annual Report on Form 10-K filed with the SEC on March 11, 2014.
In the opinion of management, all adjustments, consisting of only normal recurring adjustments that are necessary to present fairly the financial position, results of operations, and cash flows for the interim periods, have been made. The results of operations for the interim periods are not necessarily indicative of the operating results for the full fiscal year or any future periods.
Change in Method of Accounting for Inventory Valuation
Prior to January 1, 2014, inventories were stated at the lower of cost (using the weighted average cost method) or market. Effective January 1, 2014, with the final implementation of our new enterprise resource planning (“ERP”) system, we changed our method of accounting for inventories to the first-in, first-out (“FIFO”) method. We believe that the change is preferable, as the FIFO method better reflects the current value of inventories and provides more accurate matching of manufacturing costs and revenues. Due to the limited capabilities of our former ERP system, we determined that it was impracticable to retrospectively apply the FIFO costing method to prior periods. As such, prior period consolidated financial statements have not been retroactively adjusted. The cumulative effect of this change was not material.
Recent Accounting Pronouncements
On May 28, 2014, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers. The amendment requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period, which is January 1, 2017 for us. Early application is not permitted. ASU 2014-09 permits the use of either the retrospective or cumulative effect transition method. We are evaluating the effect that ASU 2014-09 will have on our consolidated financial statements and related disclosures. We have not yet selected a transition method nor have we determined the effect of the standard on our ongoing financial reporting.
Note 2 — Goodwill and Other Intangible Assets
Goodwill as of September 30, 2014 and December 31, 2013 of $12.8 million was the result of our acquisition of Pump Engineering, LLC in December 2009. During the three and nine months ended September 30, 2014, there were no changes in the recognized amount of goodwill.
The components of identifiable other intangible assets, all of which are finite-lived, as of the dates indicated were as follows (in thousands):
Accumulated impairment losses at September 30, 2014 include a $1.0 million impairment loss from 2012 for trademarks, a $31,000 loss for patents from 2007, and an $11,000 loss for patents from 2010.
Note 3 — Loss per Share
Basic and diluted net loss per share is based on the weighted average number of common shares outstanding during the period. Potential dilutive securities are excluded from the calculation of loss per share, as their inclusion would be anti-dilutive.
The following table shows the computation of basic and diluted loss per share (in thousands, except per share data):
The following potential common shares were not considered in the computation of diluted loss per share because their effect would have been anti-dilutive (in thousands):
Note 4 — Other Financial Information
We have pledged cash in connection with stand-by letters of credit and credit cards. We have deposited corresponding amounts into money market and non-interest bearing accounts at three financial institutions for these items as follows (in thousands):
We acquired Pump Engineering, LLC in December 2009. Under the terms of the purchase agreement, $3.5 million of consideration was contingent upon achievement of certain performance milestones. These performance milestones were tied to: (i) achieving certain minimum product energy efficiency metrics ($1.3 million); (ii) meeting certain product delivery time schedules ($1.2 million); and (iii) meeting certain product warranty metrics ($1.0 million). During the fourth quarter of 2010, the first two performance milestones were not met. Accordingly, we withheld payment of $2.5 million under the contractual terms of the purchase agreement.
In August 2011, the former shareholders of Pump Engineering, LLC filed a claim against us seeking damages in the amount of $2.5 million and their litigation costs. As a result, we restricted cash of $3.5 million, the entire amount of the original contingent consideration in an escrow account. On August 8, 2014, we entered into a settlement agreement (the “Agreement”) in this matter. Under the Agreement, we received $2.125 million from the established escrow account, and the plaintiffs received $1.375 million from the said escrow account with neither party admitting to any liability or responsibility. The $3.5 million of restricted cash related to the amount held in escrow was released.
Our inventories consisted of the following (in thousands):
Prepaid Expenses and Other Current Assets
Prepaid expenses and other current assets consisted of the following (in thousands):
Accrued Expenses and Other Current Liabilities
Accrued expenses and other current liabilities consisted of the following (in thousands):
Accumulated Other Comprehensive Loss
Changes in accumulated other comprehensive loss by component for the nine months ended September 30, 2014 were as follows (in thousands):
There were no reclassifications of amounts out of accumulated other comprehensive loss, as there have been no sales of securities or translation adjustments that impacted other comprehensive income during the quarter. The tax impact of the changes in accumulated other comprehensive loss was not material.
Note 5 — Investments
Our short-term and long-term investments are all classified as available-for-sale. There were no sales of available-for-sale securities during the three and nine months ended September 30, 2014.
Available-for-sale securities as of the dates indicated consisted of the following (in thousands):
Gross unrealized losses and fair values of our investments in an unrealized loss position as of the dates indicated, aggregated by investment category and length of time that the security has been in a continuous loss position, were as follows (in thousands):
Expected maturities can differ from contractual maturities because borrowers may have the right to prepay obligations without prepayment penalties. The amortized cost and fair value of available-for-sale securities that had stated maturities as of September 30, 2014 are shown below by contractual maturity (in thousands):
Note 6 — Lines of Credit
Lines of Credit
In June 2012, we entered into a loan agreement (the “2012 Agreement”) with a financial institution. The 2012 Agreement provides for a total available credit line of $16.0 million. Under the 2012 Agreement, we are allowed to draw advances not to exceed, at any time, $10.0 million as revolving loans. The total stand-by letters of credit issued under the 2012 Agreement may not exceed the lesser of the $16.0 million credit line or the credit line minus all outstanding revolving loans. At no time may the aggregate of the revolving loans and stand-by letters of credit exceed the total available credit line of $16.0 million. Revolving loans may be in the form of a base rate loan that bears interest equal to the prime rate plus 0% or a Eurodollar loan that bears interest equal to the adjusted LIBOR plus 1.25%. Stand-by letters of credit are subject to customary fees and expenses for issuance or renewal. The unused portion of the credit facility is subject to a facility fee in an amount equal to 0.25% per annum of the average unused portion of the revolving line. The 2012 Agreement also requires us to maintain a cash collateral balance equal to 101% of all outstanding advances and all outstanding stand-by letters of credit collateralized by the line of credit. The 2012 Agreement matures in June 2015 and is collateralized by substantially all of our assets. As of September 30, 2014 and December 31, 2013, there were no advances drawn under the 2012 Agreement. Stand-by letters of credit collateralized under the 2012 Agreement totaled $2.7 million and $1.3 million as of September 30, 2014 and December 31, 2013, respectively. Total cash restricted related to these stand-by letters of credit totaled $2.7 million and $1.3 million as of September 30, 2014 and December 31, 2013, respectively.
We are subject to certain financial and administrative covenants under the 2012 Agreement. As of September 30, 2014, we were in compliance with these covenants.
In 2009, we entered into a loan and security agreement (the “2009 Agreement”) with another financial institution. The 2009 Agreement, as amended, provided a total available credit line of $16.0 million. Under the 2009 Agreement, we were allowed to draw advances of up to $10.0 million on a revolving line of credit or utilize up to $15.9 million as collateral for stand-by letters of credit, provided that the aggregate of the outstanding advances and collateral did not exceed the total available credit line of $16.0 million. Advances under the revolving line of credit incurred interest based on a prime rate index or LIBOR plus 1.375%. The 2009 Agreement, as amended, also required us to maintain cash collateral balances equal to at least 101% of the face amount of all outstanding stand-by letters of credit collateralized by the line of credit and 100% of the amount of all outstanding advances. The 2009 Agreement expired at the end of May 2012, at which time we became required to maintain a cash collateral balance equal to at least 105% of the face amount of all outstanding stand-by letters of credit collateralized by the line of credit. There were no advances drawn under the 2009 Agreement’s credit line at the time it expired. Remaining stand-by letters of credit issued under the 2009 Agreement totaled $2.3 million and $3.6 million as of September 30, 2014 and December 31, 2013, respectively. Total cash restricted related to these stand-by letters of credit totaled $2.4 million and $3.7 million as of September 30, 2014 and December 31, 2013, respectively.
Note 7 — Equity
Stock Repurchase Program
In February 2014, our Board of Directors authorized a stock repurchase program under which up to three million shares, not to exceed $6.0 million in aggregate cost, of our outstanding common stock could be repurchased through December 31, 2014 at the discretion of management. We account for treasury stock using the cost method. Cost includes fees charged in connection with acquiring the treasury stock. During the three months ended September 30, 2014, 252,300 shares at an aggregate cost of $1.0 million were repurchased under this authorization. During the nine months ended September 30, 2014, 367,600 shares at an aggregate cost of $1.6 million were repurchased under this authorization.
In October 2014, an additional 329,253 shares at an aggregate cost of $1.2 million were repurchased under this authorization.
Share-Based Compensation Expense
For the three and nine months ended September 30, 2014 and 2013, we recognized share-based compensation expense related to employees and consultants as follows (in thousands):
As of September 30, 2014, total unrecognized compensation cost related to non-vested share-based awards, net of estimated forfeitures, was $3.9 million, which is expected to be recognized as expense over a weighted average period of approximately 2.98 years.
In March 2014, we granted 957,000 stock options to certain officers and other employees. The options vest over a four-year period, have an exercise price of $6.00 per share, and expire 10 years from the grant date.
Also, in March 2014, we granted 10,000 stock options to an employee. The options vest over a four-year period, have an exercise price of $5.32 per share, and expire 10 years from the grant date.
In April 2014, we granted 440,000 stock options to our President and Chief Executive Officer in lieu of his participation in the 2014 cash incentive plan. The options vest over a four-year period, have an exercise price of $4.96 per share, and expire 10 years from the grant date.
In June 2014, we granted 50,000 stock options to a certain employee as part of the offer letter of employment. The options vest over a four-year period, have an exercise price of $5.91 per share, and expire 10 years from the grant date.
In July 2014, we granted 100,000 stock options to our new Chief Financial Officer as part of his promotion. The options vest over a four-year period, have an exercise price of $4.91 per share, and expire 10 years from the grant date.
On October 1, 2014, we granted 100,000 and 180,000 stock options to our new Chief Financial Officer as the second part of his promotion and to certain other employees, respectively. The options vest over a four-year period, have an exercise price of $3.31 per share, and expire 10 years from the grant date.
On October 15, 2014, we granted 75,000 stock options to our new Chief Sales Officer as part of his offer letter of employment. The options vest over a four-year period, have an exercise price of $3.80 per share, and expire 10 years from the grant date.
On July 29, 2014, warrants to purchase 400,000 shares of common stock were exercised for 311,111 shares in lieu of cash proceeds. The remaining 88,889 warrants were cancelled and considered payment for the exercise.
Note 8 — Income Taxes
The effective tax rate for the nine months ended September 30, 2014 and 2013 was (1.4%) and (2.7%), respectively. As of December 31, 2013, a valuation allowance of approximately $13.4 million was established to reduce our deferred income tax assets to the amount expected to be realized. As such, no tax benefit related to our pre-tax loss was recognized for the three or nine months ended September 30, 2014, as there was no change in our assessment of the amount of deferred income tax assets expected to be realized.
Note 9 — Commitments and Contingencies
Operating Lease Obligations
We lease facilities under fixed non-cancellable operating leases that expire on various dates through November 2019. Future minimum lease payments consist of the following (in thousands):
The following table summarizes the activity related to the product warranty liability during the three and nine months ended September 30, 2014 and 2013 (in thousands):
Based on management’s analysis of warranty liability experience, a change in estimate of our warranty reserve of $132,000 was recorded in 2013.
We enter into purchase order arrangements with our vendors. As of September 30, 2014, there were open purchase orders for which we had not yet received the related goods or services. These arrangements are subject to change based on our sales demand forecasts, and we have the right to cancel the arrangements prior to the date of delivery. As of September 30, 2014, we had approximately $1.8 million of cancellable open purchase order arrangements related primarily to materials and parts.
We enter into indemnification provisions under our agreements with other companies in the ordinary course of business, typically with customers. Under these provisions, we generally indemnify and hold harmless the indemnified party for losses suffered or incurred by the indemnified party as a result of our activities, generally limited to personal injury and property damage caused by our employees at a customer’s desalination plant in proportion to the employee’s percentage of fault for the accident. Damages incurred for these indemnifications would be covered by our general liability insurance to the extent provided by the policy limitations. We have not incurred material costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, the estimated fair value of these agreements is not material. Accordingly, we had no liabilities recorded for these agreements as of September 30, 2014 and December 31, 2013.
In certain cases, we issue warranty and product performance guarantees to our customers for amounts ranging from 10% to 30% of the total sales agreement to endorse the execution of product delivery and the warranty of design work, fabrication, and operating performance. These guarantees, generally in the form of stand-by letters of credit or bank guarantees secured by stand-by letters of credit, typically remain in place for periods ranging up to 24 months and in some cases up to 59 months, and relate to the underlying product warranty period. The stand-by letters of credit are collateralized by restricted cash and our credit facility. Of the $5.0 million in outstanding stand-by letters of credit at September 30, 2014, $2.3 million was issued under the 2009 Agreement and $2.7 million was issued under the 2012 Agreement. The stand-by letters of credit outstanding at September 30, 2014 were collateralized by restricted cash of $5.1 million.
Note 9 – Commitments and Contingencies, under the caption “Litigation” of our Annual Report on Form 10-K filed with the SEC on March 11, 2014, provides information on certain litigation in which we are involved. Unfavorable rulings, judgments, or settlement terms regarding these litigation matters could have a material adverse impact on our business, financial condition, results of operations, and cash flows. Although none of the litigation matters can be quantified with absolute certainty, we have established accruals covering exposure and relating to contingencies to the extent that they are reasonably estimable and probable based on available facts.
See Note 4 – “Equity – Restricted Cash,” for a discussion of our August 2014 settlement of the litigation concerning the Pump Engineering, LLC acquisition.
On September 10, 2014, the Company terminated the employment of Mr. Borja Sanchez-Blanco, Senior Vice President of Sales, for cause on the basis of breach of duty of trust and conduct leading to conflicts of interest. On October 3, 2014, Mr. Blanco filed a complaint with the labor commissioner in Madrid, Spain against the Company and its subsidiary Energy Recovery Iberia SL. Mr. Blanco alleges among other things, that he was terminated without cause. The complaint alleges wages due (salary and bonus) of approximately €567,000 and alleged stock option gains of €630,000, as a result of the alleged termination without cause. At this time, no reserve has been accrued as we have determined that an award to Mr. Blanco is not probable.
Note 10 — Business Segment and Geographic Information
We manufacture and sell high-efficiency energy recovery devices and pumps as well as related services under one reportable segment. Our chief operating decision-maker is the chief executive officer (“CEO”). The CEO reviews financial information presented on a consolidated basis for purposes of making operating decisions and assessing financial performance. Accordingly, we have concluded that we have one reportable segment.
The following geographic information includes net revenue attributable to our domestic and international customers based on the customers’ requested delivery locations, except for certain cases in which the customer directed us to deliver our products to a location that differs from the known ultimate location of use. In such cases, the ultimate location of use, rather than the delivery location, is reflected in the table below (in thousands, except percentages):
All of our long-lived assets were located in the United States at September 30, 2014 and December 31, 2013.
Note 11 — Concentrations
Customers accounting for 10% or more of our accounts receivable and unbilled receivables were as follows:
Revenue from customers representing 10% or more of net revenue varies from period to period. For the periods indicated, customers representing 10% or more of net revenue were:
Note 12 — Fair Value Measurements
The authoritative guidance for measuring fair value provides a hierarchy that prioritizes the inputs to valuation techniques used in measuring fair value as follows:
Level 1 — Quoted prices (unadjusted) in active markets for identical assets or liabilities;
Level 2 — Inputs other than quoted prices included within Level 1 that are either directly or indirectly observable; and
Level 3 — Unobservable inputs in which little or no market activity exists, therefore requiring an entity to develop its own assumptions that market participants would use in pricing.
The carrying values of cash and cash equivalents, restricted cash, accounts receivable, unbilled receivables, accounts payable, and other accrued expenses approximate fair value due to the short-term maturity of those instruments. For our investments in available-for-sale securities, if quoted prices in active markets for identical investments are not available to determine fair value (Level 1), then we use quoted prices for similar assets or inputs other than quoted prices that are observable either directly or indirectly (Level 2). The investments included in Level 2 consist primarily of certificates of deposits; commercial paper; and municipal, corporate, and agency obligations.
The carrying amount of the contingent consideration arising from our acquisition of Pump Engineering, LLC was measured at fair value on a recurring basis using unobservable inputs in which little or no market activity existed (Level 3). The estimated fair value of the contingent consideration was determined based entirely on management’s assessment of the weighted probability of payment under various scenarios. See Note 4 – “Equity – Restricted Cash,” for a discussion of our August 2014 settlement of the litigation concerning this contingent consideration.
The fair value of financial assets and liabilities measured on a recurring basis for the indicated periods was as follows (in thousands):
* Included in Accrued Expenses and Other Current Liabilities and Other Non-Current Liabilities.
The reconciliation of the beginning and ending balances for assets and liabilities measured on a recurring basis using significant unobservable inputs (Level 3) for the period ended September 30, 2014 was as follows (in thousands):

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The discussion in this item and in other items of this Form 10-Q contains forward-looking statements within the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995. Forward-looking statements in this report include, but are not limited to, statements about our expectations, objectives, anticipations, plans, hopes, beliefs, intentions, or strategies regarding the future.
Forward-looking statements that represent our current expectations about future events are based on assumptions and involve risks and uncertainties. If the risks or uncertainties occur or the assumptions prove incorrect, then our results may differ materially from those set forth or implied by the forward-looking statements. Our forward-looking statements are not guarantees of future performance or events.
Words such as “expects,” “anticipates,” “believes,” “estimates,” variations of such words, and similar expressions are also intended to identify such forward-looking statements. These forward-looking statements are subject to risks, uncertainties, and assumptions that are difficult to predict; therefore, actual results may differ materially and adversely from those expressed in any forward-looking statements. Forward-looking statements in this report include, without limitation, statements about the following:
You should not place undue reliance on these forward-looking statements, which reflect management’s opinions only as of the date of the filing of this Quarterly Report on Form 10-Q. All forward-looking statements included in this document are subject to certain risks and uncertainties, which could cause actual results to differ materially from those projected in the forward-looking statements, as disclosed from time to time in our reports on Forms 10-K, 10-Q, and 8-K as well as in our Annual Reports to Stockholders and, if necessary, updated in “Part II, Item 1A: Risk Factors.” We assume no obligation to update any such forward-looking statements. It is important to note that our actual results could differ materially from the results set forth or implied by our forward-looking statements.
We are in the business of designing, developing, and manufacturing energy recovery devices to transform untapped energy into reusable energy from industrial fluid flows and pressure cycles. Our company was founded in 1992, and we introduced the initial version of our Pressure Exchanger® energy recovery device in early 1997. In December 2009, we acquired Pump Engineering, LLC, which manufactured centrifugal energy recovery devices known as turbochargers and high-pressure pumps.
Our energy recovery devices are primarily used in seawater reverse osmosis desalination. Since 2011, we have invested significant research and development costs to expand into other pressurized fluid flow industries such as oil and gas.
Our revenue is principally derived from the sale of our energy recovery devices. We also derive revenue from the sale of our high-pressure and circulation pumps which we manufacture and sell in connection with our energy recovery devices for use in desalination plants. Additionally, we receive revenue from the sale of spare parts and services, including start-up and commissioning services that we provide to our customers. The three and nine months ended September 30, 2014 also includes revenue from shipments of energy recovery devices for oil & gas customers pertaining to an operating lease with a customer in Saudi Arabia.
A significant portion of our net revenue typically has been generated from sales to a limited number of large engineering, procurement, and construction (“EPC”) firms that are involved with the design and construction of large desalination plants. Sales to these firms often involve a long sales cycle that can range from 6 to 16 months, and in some cases, up to 24 months. A single large desalination project can generate an order for numerous energy recovery devices and generally represents a significant revenue opportunity. We also sell our devices to many small- to medium-sized original equipment manufacturers (“OEMs”) which commission smaller desalination plants, order fewer energy recovery devices per plant, and have shorter sales cycles.
In the oil and gas market, we are generating lease revenue from the deployment of an IsoGen™ system in Saudi Arabia. Additionally, there are a number of pilot projects to which we have deployed some of our oil and gas devices that have not, as of yet, generated revenue.
We often experience substantial fluctuations in net revenue from quarter to quarter and from year to year due to the fact that a single order for our energy recovery devices by a large EPC firm for a particular plant may represent significant revenue. In addition, historically our EPC customers tend to order a significant amount of equipment for delivery in the fourth quarter, and as a consequence, a significant portion of our annual sales typically occurs during that quarter. During the fourth quarter of 2013, five large mega-project (“MPD”) shipments contributed to a significant increase in net revenue, making it the strongest revenue quarter in the Company’s history. Normal seasonality trends generally show our lowest revenue in the first quarter of the year, with the first quarter of 2014 having followed that trend. Net revenue in the second and third quarter of 2014, which historically have included one or more MPD shipments, was adversely impacted by the timing of MPD shipments, and as such, did not include any MPD shipments.
A limited number of our customers account for a substantial portion of our net revenue and accounts receivable. Revenue from customers representing 10% or more of net revenue varies from period to period. For the three and nine months ended September 30, 2014, no customer accounted for more than 10% of our net revenue. For the three months ended September 30, 2013, three customers accounted for 17%, 16%, and 10%, respectively of our net revenue. No other customer accounted for more than 10% of our net revenue during this period. For the nine months ended September 30, 2013, no customer accounted for more than 10% of our net revenue.
During the three and nine months ended September 30, 2014 and 2013, the majority of our net revenue was attributable to sales outside of the United States. We expect sales outside of the United States to remain a significant portion of our net revenue for the next few years.
Our condensed consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States, or GAAP. These accounting principles require us to make estimates and judgments that can affect the reported amounts of assets and liabilities as of the date of the condensed consolidated financial statements as well as the reported amounts of revenue and expense during the periods presented. We believe that the estimates and judgments upon which we rely are reasonable based upon information available to us at the time that we make these estimates and judgments. To the extent that there are material differences between these estimates and actual results, our consolidated financial results will be affected. The accounting policies that reflect our more significant estimates and judgments and which we believe are the most critical to aid in fully understanding and evaluating our reported financial results are revenue recognition; allowance for doubtful accounts; allowance for product warranty; valuation of stock options; valuation and impairment of goodwill, long-lived assets, and acquired intangible assets; useful lives for depreciation and amortization; valuation adjustments for excess and obsolete inventory; deferred taxes and valuation allowances on deferred tax assets; and evaluation and measurement of contingencies, including contingent consideration.
