The accompanying consolidated financial statements include our accounts and those of our wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated upon consolidation. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Certain of our accounts, including inventories, long-lived assets, goodwill, identifiable intangibles, deferred income tax valuation allowances and product warranty reserves, are particularly impacted by estimates.

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. We grant credit to customers and generally require no collateral. To minimize our risk, we perform ongoing credit evaluations of our customers' financial condition. The allowance for doubtful accounts is our best estimate of the amount of probable credit losses in our existing accounts receivable. We determine the allowance based on historical write-off experience and the aging of such receivables, among other factors. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. We do not have any off-balance sheet credit exposure related to our customers. Bad debt expense was $48 and $62 for the years ended December 31, 2011 and 2010, respectively. Cash flows from accounts receivable are recorded in operating cash flows.

Inventory is valued at standard cost, which approximates actual cost computed on a first-in, first-out basis, not in excess of market value. Cash flows from the sale of inventory are recorded in operating cash flows. On a quarterly basis, we review our inventories and record excess and obsolete inventory charges based upon our established objective excess and obsolete inventory criteria. These criteria identify material that has not been used in a work order during the prior twelve months and the quantity of material on hand that is greater than the average annual usage of that material over the prior three years. In certain cases, additional excess and obsolete inventory charges are recorded based upon current industry conditions, anticipated product life cycles, new product introductions and expected future use of the inventory. The charges for excess and obsolete inventory we record establish a new cost basis for the related inventory. We incurred excess and obsolete inventory charges of $403 and $344 for the years ended December 31, 2011 and 2010, respectively.

Machinery and equipment are stated at cost. As further discussed below under "Goodwill, Intangible and Long-Lived Assets," machinery and equipment that has been determined to be impaired is written down to its fair value at the time of the impairment. Depreciation is based upon the estimated useful life of the assets using the straight-line method. The estimated useful lives range from one to seven years. Leasehold improvements are recorded at cost and amortized over the shorter of the lease term or the estimated useful life of the asset. Total depreciation expense, including amortization of assets acquired under capital leases, was $259 and $261 for the years ended December 31, 2011 and 2010, respectively. Expenditures for maintenance and repairs are charged to operations as incurred.

Goodwill is assessed for impairment at least annually in the fourth quarter, on a reporting unit basis, or more frequently when events and circumstances occur indicating that the recorded goodwill may be impaired. The goodwill impairment assessment is based upon a combination of the income approach, which estimates the fair value of our reporting units based upon a discounted cash flow approach, and the market approach which estimates the fair value of our reporting units based upon comparable market multiples. This fair value is then reconciled to our market capitalization at year end with an appropriate control premium. The determination of the fair value of our reporting units requires management to make significant estimates and assumptions including the selection of appropriate peer group companies, control premiums, discount rate, terminal growth rates, forecasts of revenue and expense growth rates, changes in working capital, depreciation, amortization and capital expenditures. Changes in assumptions concerning future financial results or other underlying assumptions would have a significant impact on either the fair value of the reporting unit or the amount of the goodwill impairment charge.

During the goodwill impairment assessment, we perform a Step I test to identify potential impairment, in which the fair value of a reporting unit is compared with its book value. If the book value of a reporting unit exceeds its fair value, a Step II test is performed in which the implied fair value of goodwill is compared with the carrying amount of goodwill. If the carrying amount of goodwill exceeds the implied fair value, an impairment loss is recorded in an amount equal to that excess. Indefinite-lived intangible assets are assessed for impairment at least annually in the fourth quarter, or more frequently if events or changes in circumstances indicate that the asset might be impaired. The impairment test consists of a comparison of the fair value of an intangible asset with its carrying amount. If the carrying amount of an intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess.

Long-lived assets, which consist of finite-lived intangible assets and property and equipment, are assessed for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable or that the useful lives of these assets are no longer appropriate. Each impairment test is based on a comparison of the estimated undiscounted cash flows to the recorded value of the asset. If impairment is indicated, the asset is written down to its estimated fair value. The cash flow estimates used to determine the impairment, if any, contain management's best estimates using appropriate assumptions and projections at that time.

We account for stock-based compensation in accordance with Accounting Standards Codification ("ASC") Topic 718 (Compensation - Stock Compensation) which requires that employee share-based equity awards be accounted for under the fair value method and requires the use of an option pricing model for estimating fair value, which is then amortized to expense over the service periods. See further disclosures related to our stock-based compensation plan in Note 15.

We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the price is fixed or determinable, and collectibility is reasonably assured. Sales of our products are made through our sales employees, third-party sales representatives and distributors. There are no differences in revenue recognition policies based on the sales channel. We do not provide our customers with rights of return or exchanges. Revenue is generally recognized upon product shipment. Our customers' purchase orders do not typically contain any customer-specific acceptance criteria, other than that the product performs within the agreed upon specifications. We test all products manufactured as part of our quality assurance process to determine that they comply with specifications prior to shipment to a customer. To the extent that any customer purchase order contains customer-specific acceptance criteria, revenue recognition is deferred until customer acceptance.

With respect to sales tax collected from customers and remitted to governmental authorities, we use a net presentation in our consolidated statement of operations. As a result, there are no amounts included in either our net revenues or cost of revenues related to sales tax.

We recognize a liability for restructuring costs at fair value only when the liability is incurred. The three main components of our restructuring plans have been related to workforce reductions, the consolidation of excess facilities and asset impairments. Workforce-related charges are accrued when it is determined that a liability has been incurred, which is generally after individuals have been notified of their termination dates and expected severance benefits. Plans to consolidate excess facilities result in charges for lease termination fees and future commitments to pay lease charges, net of estimated future sub-lease income. We recognize these charges when we have vacated the premises. In addition, as a result of plans to consolidate excess facilities, we may incur other associated costs such as charges to relocate inventory, equipment or personnel. We recognize charges for other associated costs when these costs are incurred, which is generally when the goods or services have been provided to us. Assets that may be impaired consist of property, plant and equipment and intangible assets. Asset impairment charges are based on an estimate of the amounts and timing of future cash flows related to the expected future remaining use and ultimate sale or disposal of the asset.

For our foreign subsidiaries whose functional currency is not the U.S. dollar, assets and liabilities are translated using the exchange rate in effect at the balance sheet date. The results of operations are translated using an average exchange rate for the period. The effects of rate fluctuations in translating assets and liabilities of these international operations into U.S. dollars are included in accumulated other comprehensive earnings in stockholders' equity. Transaction gains or losses are included in net earnings. For the years ended December 31, 2011 and 2010, foreign currency transaction losses were $3 and $20, respectively.

The asset and liability method is used in accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for operating loss and tax credit carryforwards and for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the results of operations in the period that includes the enactment date. A valuation allowance is recorded to reduce the carrying amounts of deferred tax assets if it is more likely than not that such assets will not be realized.

Net earnings per common share - basic is computed by dividing net earnings by the weighted average number of common shares outstanding during each period. Net earnings per common share - diluted is computed by dividing net earnings by the weighted average number of common shares and common share equivalents outstanding during each period. Common share equivalents represent stock options and unvested shares of restricted stock and are calculated using the treasury stock method. Common share equivalents are excluded from the calculation if their effect is anti-dilutive.

The table below sets forth, for the periods indicated, a reconciliation of weighted average common shares outstanding - basic to weighted average common shares and common share equivalents outstanding - diluted and the average number of potentially dilutive securities and their respective weighted average exercise prices that were excluded from the calculation of diluted earnings per share because their effect was anti-dilutive:

	Years Ended December 31,
	2011		2010

Weighted average common shares outstanding - basic		10,147,708		10,019,000
Potentially dilutive securities:
Employee stock options and unvested shares of restricted stock		137,913		122,552
Weighted average common shares outstanding - diluted		10,285,621		10,141,552
Average number of potentially dilutive securities excluded from calculation		129,217		422,260
Weighted average exercise price of excluded securities	$	3.70	$	3.42

In January 2010, the Financial Accounting Standards Board (the "FASB") issued an amendment to an accounting standard regarding disclosure guidance with respect to fair value measurements. Specifically, the new guidance requires disclosure of amounts transferred in and out of Levels 1 and 2 fair value measurements, a reconciliation presented on a gross basis rather than a net basis of activity in Level 3 fair value measurements, greater disaggregation of the assets and liabilities for which fair value measurements are presented and more robust disclosure of the valuation techniques and inputs used to measure Level 2 and 3 fair value measurements. This amendment was effective for interim and annual reporting periods beginning after December 15, 2009, with the exception of the new guidance around the Level 3 activity reconciliations, which was effective for fiscal years beginning after December 15, 2010. The adoption of this amendment did not have any impact on our consolidated financial statements.

In July 2010, the FASB issued an amendment to an accounting standard that requires additional disclosure about the credit quality of financing receivables, such as aging information and credit quality indicators. Both new and existing disclosures must be disaggregated by portfolio segment or class, if applicable. The disaggregation of information is based on how allowances for credit losses are developed and how credit exposure is managed. This amendment was effective for interim periods and fiscal years ending after December 15, 2010. The adoption of this amendment did not have any impact on our consolidated financial statements.

In December 2010, the FASB issued an amendment to goodwill impairment testing. The amendment modifies Step I of the goodwill impairment test for reporting units with zero or negative carrying amounts. For those reporting units, an entity is required to perform Step II of the goodwill impairment test if it is more likely than not that a goodwill impairment exists. In determining whether it is more likely than not that goodwill impairment exists, an entity should consider whether there are any adverse qualitative factors indicating that impairment may exist. The qualitative factors are consistent with the existing guidance and examples, which require that goodwill of a reporting unit be tested for impairment between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The amendment is effective for fiscal years, and interim periods within those years, beginning after December 15, 2010. The adoption of this guidance did not have any impact on our consolidated financial statements.

In December 2010, the FASB issued an amendment to the disclosure of supplementary pro forma information for business combinations. The amendment specifies that if a public entity presents comparative financial statements, the entity should disclose revenue and earnings of the combined entity as though the business combination that occurred during the current year had occurred as of the beginning of the comparable prior annual reporting period only. The amendment also expands the supplemental pro forma disclosures to include a description of the nature and amount of material, nonrecurring pro forma adjustments directly attributable to the business combination included in the reported pro forma revenue and earnings. The amendment is effective prospectively for 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, 2010. We will implement this guidance for any business acquisitions we consummate after the effective date.

In June 2011, the FASB issued an amendment to disclosures about comprehensive income. Under the amendment, an entity has the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. In both choices, an entity is required to present each component of net income along with total net income, each component of other comprehensive income along with a total for other comprehensive income, and a total amount for comprehensive income. This amendment eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders' equity. Reclassification adjustments between net income and other comprehensive income must be shown on the face of the statement(s), with no resulting change in net earnings. The amendment does not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. The amendment is effective for fiscal years beginning after December 15, 2011. We do not expect the adoption of this amendment to have a material impact on our consolidated financial statements.

In September 2011, the FASB issued an amendment to existing guidance on the assessment of goodwill impairment which provides an entity the option to first assess qualitative factors to determine whether it is necessary to perform the current two-step test for goodwill impairment. If an entity believes, as a result of its qualitative assessment, that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, the quantitative impairment test is required. Otherwise, no further testing is required. The update also amends the examples of events or circumstances that would be considered in a goodwill impairment evaluation. The amendment is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. However, an entity can choose to adopt this guidance early even if its annual test date is before the issuance of the final standard, provided that the entity has not yet performed its 2011 annual impairment test or issued its financial statements. We do not expect the adoption of this amendment to have a material impact on our consolidated financial statements.
