	Note 2. Summary of Significant Accounting Policies
	Basis of Presentation
	The accompanying condensed consolidated balance sheets as of September 30, 2013 and the condensed consolidated statements of operations for the three and nine months ended September 30, 2013 and 2012 and cash flows for the nine months ended September 30, 2013 and 2012 are unaudited. These statements should be read in conjunction with the audited consolidated financial statements and related notes, together with management’s discussion and analysis of financial position and results of operations, contained in our Annual Report on Form 10-K for the year ended December 31, 2012, filed with the U.S. Securities and Exchange Commission (the “SEC”) on February 21, 2013. The operating results for the three and nine month periods ended September 30, 2013 and cash flows for the nine month period ended September 30, 2013 are not necessarily indicative of the results that will be achieved for the full fiscal year or for future periods.
	The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States, or (“GAAP”), and pursuant to the rules and regulations of the SEC for interim financial reporting. In the opinion of our management, the unaudited condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2012 and include all adjustments necessary for the fair presentation of our financial position as of September 30, 2013 and our results of operations for the three and nine months ended September 30, 2013 and 2012 and our cash flows for the nine month period ended September 30, 2013 and 2012. The condensed consolidated balance sheet as of December 31, 2012 has been derived from the December 31, 2012 audited financial statements. The interim financial information contained in this Quarterly Report is not necessarily indicative of the results to be expected for any other interim period or for the entire year.
	The condensed consolidated financial statements include the accounts of Guidance and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.
	The Company’s restricted stock award agreements provide that holders of the restricted stock awards shall have all the rights of a stockholder upon the grant date, including the right to vote as a stockholder.  As such, these shares are considered issued and outstanding on the date of grant. As of December 31, 2012, the Company previously excluded unvested restricted stock awards from the presented quantity of common shares issued and outstanding. The Company has increased the number of common shares issued and outstanding by 2,511,000 as of December 31, 2012 to reflect these unvested restricted stock awards.
	Use of Estimates and Assumptions
	The preparation of financial statements in conformity with GAAP requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate these estimates, including those related to revenue recognition, share-based compensation, bad debts, income taxes, contingent consideration, commitments, contingencies and litigation. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results may differ from these estimates.
	Cash and Cash Equivalents
	We invest excess cash in money market funds and highly liquid debt instruments of the US government and its agencies. Highly liquid investments with stated maturities of three months or less from the date of purchase are classified as cash and cash equivalents.
	Fair Value of Financial Instruments
	The carrying amounts of cash equivalents, accounts receivable and accounts payable approximate fair value because of the short-term maturities of these instruments. Based on borrowing rates currently available to us for borrowings with similar terms, the carrying values of our capital lease obligations also approximate fair value.
	Trade Receivables
	Trade receivables are carried at original invoice amount less an allowance for doubtful accounts. The allowance is established through a provision for bad debt expense, which is included in general and administrative expenses. We determine the adequacy of this allowance by evaluating individual customer accounts receivable, through consideration of the customer’s financial condition, credit history and current economic conditions. In addition, we analyze our historical credit loss history and apply these loss rates to our current accounts receivable balances to verify the reasonableness of our allowance. Trade receivables are written off when deemed uncollectible. A trade receivable is generally considered past due if any portion of the receivable balance is outstanding for more than 30 days unless alternate terms are provided.
	Inventory
	Inventory is comprised of hardware components, packaged software components and finished goods and is valued at the lower of cost or market, using the weighted average cost method. We conduct quarterly inventory reviews for obsolescence, and inventory considered unlikely to be sold is adjusted to net realizable value.
	Business Combinations
	The purchase price of an acquisition is allocated to the underlying assets acquired and liabilities assumed based upon their estimated fair values at the date of acquisition. To the extent the purchase price exceeds the fair value of the net identifiable tangible and intangible assets acquired and liabilities assumed, such excess is allocated to goodwill. We determine the estimated fair values after review and consideration of relevant information including discounted cash flows, quoted market prices and estimates made by management. Accordingly, these can be affected by certain performance measurements and other factors over time, which may cause final amounts to differ materially from original estimates. We adjust the preliminary purchase price allocation, as necessary, up to periods of one year after the acquisition closing date as we obtain more information regarding asset valuations and liabilities assumed.  We refer to this preliminary purchase price allocation period as the measurement period.
	Goodwill acquired in business combinations is assigned to the reporting unit(s) expected to benefit from the combination as of the acquisition date.  Acquisition related costs are recognized separately from the acquisition and are expensed as incurred.
	Amortization of Intangible Assets with Finite Lives
	Intangible assets with finite lives are recorded at their fair value at the time of acquisition.  With the exception of our customer relationships intangible asset, which is amortized on a double-declining basis, the acquisition date fair values of such assets are amortized on a straight-line basis over the estimated useful lives.
	Goodwill and Indefinite-Lived Intangibles
	Goodwill represents the excess of purchase price over fair value of net assets acquired and is assigned to a reporting unit at the date the goodwill is initially recorded. Goodwill and indefinite-lived intangible assets are not amortized but evaluated for impairment annually, or whenever events or changes in circumstances indicate that the value may not be recoverable.  Commencing on January 1, 2013, the Company adopted the ASU 2011-08 issued by the Financial Accounting Standards Board (“FASB”) for the revised guidance on “Testing of Goodwill for Impairment.”  Under this guidance, the Company has the option to choose whether it will apply the qualitative assessment first before the quantitative assessment.  If a quantitative assessment is necessary a two-step test is performed at the reporting unit level to assess goodwill for impairment. First, the fair value of the reporting unit is compared to its carrying value. If the fair value exceeds the carrying value, the reporting unit is not impaired and no further testing is performed. The second step is performed if the carrying value exceeds the fair value. If the carrying value of the reporting unit exceeds its implied fair value, an impairment loss equal to the difference will be recorded. Indefinite-lived intangible assets are assessed for impairment by comparing the carrying value of the assets with their fair values.
	Application of the impairment test requires significant judgment to estimate the fair value. Changes in estimates and assumptions could materially affect the determination of fair value and/or impairment.
	Concentrations of Credit Risk
	Financial instruments that potentially subject us to significant concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. We restrict our investments in cash and cash equivalents to financial institutions, US government or federal agency instruments and obligations of corporations with high credit ratings. At September 30, 2013, the majority of our cash balances were held at financial institutions located in California in accounts that are insured by the Federal Deposit Insurance Corporation for up to $250,000. Uninsured balances aggregate approximately $16.2 million as of September 30, 2013.  At September 30, 2013, all of our cash equivalents consisted of financial institution obligations. We periodically perform credit evaluations of our customers and maintain reserves for potential losses on our accounts receivable. We do not believe we are subject to concentrations of credit risk with respect to such receivables.
	Revenue Recognition
	We generate revenues principally from the sale of EnCase®Enterprise and EnCase® Forensic software products.  Revenues associated with the sale of software licenses and revenues associated with forensic hardware sales are referred to as product revenues.  Following the acquisition of CaseCentral, Inc. (“CaseCentral”) in February 2012, we have revenue associated with cloud-based document review and production SaaS, which is referred to as subscription revenues.  Revenues are also generated from training courses, implementation services and consulting services in which we assist customers with the performance of digital investigations and train their IT and legal professionals in the use of our software products, which we collectively refer to as services revenues.  Our proprietary products are generally sold with one to three years of maintenance, which can be renewed at a stated renewal rate and is referred to as maintenance revenues.
	We recognize revenue in accordance with Accounting Standards Update (“ASU”) 2009-13, Multiple-Deliverable Revenue Arrangements, (amendment to Accounting Standards Codification (“ASC”) Topic 605, Revenue Recognition), Software Industry-Revenue Recognition topic (ASC 985-605) and Revenue Recognition (ASC 605).  While the standards govern the basis for revenue recognition, significant judgment and the use of estimates are required in connection with the allocation of revenues between product, subscription, services and maintenance revenues, as well as the amount of deferred revenues to be recognized in each accounting period.
	Revenue Recognition Criteria. In general, we recognized revenue when the following criteria have been met:
	·                  Persuasive evidence of an arrangement: If we either enter into contracts or receive written purchase orders issued by a customer that legally bind us and the customer, we consider that as evidence of an arrangement.
	·                  Delivery: We deem delivery of a product to have occurred when the title and risk of ownership have passed to the buyer. Services revenues are recognized as delivered.
	·                  Fixed or determinable fee: We consider the fee to be fixed or determinable if the fee is not subject to refund or adjustment and the payment terms are within normal established practices. If the fee is not fixed or determinable, we recognize revenues as amounts become due and payable provided all other revenue recognition criteria have been met.
	·                  Collection is deemed probable: We conduct a credit review for all significant transactions at the time of the arrangement to determine the credit-worthiness of the customer. Collection is deemed probable if we have a reasonable basis to expect that a customer will pay amounts due under an arrangement as they become due.
	Revenue Recognition for Software Products and Software-Related Services (Software Elements)
	Software product revenues.  The timing of software product revenues recognition is dependent on the nature of the product sold. We do not have any product offerings where software components and non-software components function together to deliver the tangible product’s essential functionality.
	EnCase® Enterprise Solutions and EnCase® Forensic Solutions: Revenues associated with these arrangements, exclusive of amounts allocated to maintenance and other undelivered elements, for which we have vendor-specific objective evidence of fair value (“VSOE”), is recognized upon delivery, provided that all other criteria for revenue recognition have been met.  Revenues associated with term licenses are recognized ratably over the term of the license.
	Services and maintenance revenues. The majority of our consulting and implementation services are performed under per hour, or fixed fee arrangements. Revenues from such services are recognized as the services are provided or upon expiration of the contractual service period.
	Training revenues are either recognized on a per-class basis upon a participant’s attendance or, for those customers who have subscribed to our Annual Training Passport program, revenues are recognized ratably over the annual period.
	Revenues related to technical support and software updates on a when-and-if available basis is referred to as maintenance revenues. We recognize maintenance revenues ratably over the applicable maintenance period. We determine the amount of maintenance revenues to be deferred through reference to substantive maintenance renewal provisions contained in multiple element arrangements. We consider substantive maintenance provisions to be provisions where the cost of the maintenance renewal, stated in the contract with our customer as a percentage of the product fee, is comparable to the normal pricing for maintenance only renewals.
	Revenue Recognition for Multiple-Element Arrangements — Software Products and Software-Related Services (Software Arrangements)
	We often enter into arrangements with customers that purchase both software products and software-related services from us at the same time, or within close proximity of one another (referred to as software-related multiple-element arrangements).  Such software-related multiple-element arrangements may include the sale of our software products, software maintenance services, which includes license updates and product support, consulting/implementation services and training whereby the software license delivery is followed by the subsequent delivery of the other elements.  For those software-related multiple-element arrangements, we have applied the residual method to determine the amount of software license revenues to be recognized pursuant to ASC 985-605.  Under the residual method, if VSOE exists for the undelivered elements, this amount is deferred with the remaining, or residual, portion of the arrangement consideration recognized upon delivery of the software license, provided all other revenue recognition criteria are met.
	Revenue Recognition for Hardware and Subscription (SaaS) Revenues (Nonsoftware Elements)
	Hardware product revenues. Revenues associated with the sale of forensic hardware is recognized upon shipment to the customers which include certain resellers, provide that all other criteria for revenue recognition have been met.
	Subscription revenues.  Customers pay subscription fees to access our cloud-based document review and production software; however, they may not take possession of the software at any time during the term of the agreement.  In general, we recognize revenues for subscription fees on a straight-line basis over the contract period commencing on the date the subscription is made available to the customer.  Usage-based fees, which are determined monthly, are recognized when incurred.
	Revenue Recognition for Multiple-Element Arrangements — Hardware, SaaS and Nonsoftware-Related Services (Nonsoftware Arrangements)
	We enter into arrangements with customers that purchase both nonsoftware-related SaaS subscription and nonsoftware-related services, such as consulting services, at the same time or within close proximity of one another (referred to as nonsoftware multiple-element arrangements).  Each element within a nonsoftware multiple-element arrangement is accounted for as a separate unit of accounting provided the following criteria are met: the delivered products or services have value to the customer on a standalone basis; and for an arrangement that includes a general right of return relative to the delivered products or services, delivery or performance of the undelivered product or service is considered probable and is substantially controlled by us.  We consider a deliverable to have standalone value if the product or service is sold separately by us or another vendor, or could be resold by the customer.  Further, our revenue arrangements generally do not include a general right of return relative to the delivered products.  Where the aforementioned criteria for a separate unit of accounting are not met, the deliverable is combined with the undelivered element and treated as a single unit of accounting for the purposes of allocation of the arrangement consideration and revenue recognition.  For those units of accounting that include more than one deliverable but are treated as a single unit of accounting, we generally recognize revenues over the delivery period.  For the purposes of revenue classification of the elements that are accounted for as a single unit of accounting, we allocate revenue to the respective revenue line items within our consolidated statements of operations based on a rational and consistent methodology utilizing our best estimate of relative selling prices of such elements.
	For our nonsoftware multiple-element arrangements, we allocate revenue to each element based on a selling price hierarchy at the arrangement’s inception.  The selling price for each element is based upon the following selling price hierarchy:  VSOE, if available; third party evidence (“TPE”) if VSOE is not available; or best estimate of selling price (“BESP”) if neither VSOE nor TPE are available.  A description as to how we determine VSOE, TPE and BESP is provided below:
	·                  VSOE.  VSOE is determined based on its historical pricing and discounting practices for the specific product or service when sold separately.  In determining VSOE, we require that a substantial majority of the selling prices for these services fall within a reasonably narrow pricing range.
	·                  TPE.  When VSOE cannot be established for deliverables in a multiple element arrangement, judgment is applied with respect to whether we can establish a selling price based on TPE.  TPE is determined based on competitor prices for similar deliverables when sold separately.  Generally, our go-to-market strategy differs from that of our peers and our offerings contain a significant level of differentiation such that comparable pricing of services with similar functionality has not been obtained.  Furthermore, we have been unable to reliably determine selling prices of similar competitive services on a stand-alone basis.  As a result, we have not been able to establish selling prices based on TPE.
	·                  BESP.  When VSOE or TPE is unable to be established, we use BESP in our allocation of arrangement consideration.  The objective of BESP is to determine the price at which we would transact a sale if the service were sold on a stand-alone basis.  We determine BESP for deliverables by considering multiple factors including but not limited to prices we charge for similar offerings, market conditions, competitive landscape and pricing practices.
	Revenue Recognition for Multiple-Element Arrangements — Arrangements with Software and Nonsoftware Elements
	We also enter into multiple-element arrangements that may include a combination of our various software-related and nonsoftware-related products and services.  In such arrangements, we first allocate the total arrangement consideration based on the relative selling prices to the software group of elements as a whole and to the nonsoftware group of elements.  We then further allocate consideration with the software group and nonsoftware group to the respective elements within that group following the guidance in ASC 985-605 and our policies described above.  After the arrangement consideration has been allocated to the elements, we recognize revenue for each respective element in the arrangement as described above.

The results of operations of CaseCentral have been included in the Company’s financial statements subsequent to the acquisition date.  We acquired CaseCentral to extend our market leadership by delivering a complete and integrated platform solving the e-discovery needs of corporate and government customers.
	In connection with the CaseCentral acquisition, we may be required to pay former CaseCentral shareholders additional consideration based on three 12-month periods (“earn-out periods”) starting April 1, 2012.  The amount of contingent consideration payable with respect to each of the earn-out periods is equal to 35% of certain qualifying CaseCentral SaaS revenues and EnCase® eDiscovery revenues in excess of $11.1 million during each of the three earn-out periods and is limited to certain cumulative limits.  No contingent consideration was paid for the period ending April 1, 2013.  At September 30, 2013, the fair value of the contingent consideration, which is calculated by summing the present values of various probability-weighted possible outcomes, was estimated to be $0.6 million and was included as a liability on our condensed consolidated balance sheets.  We incurred $2.0 million in acquisition-related costs during the three months ended March 31, 2012, which was expensed as incurred and included in general and administrative expenses.  No acquisition-related costs were incurred for the nine months ended September 30, 2013.  For a detailed description of the CaseCentral acquisition, please refer to Note 3 in our Annual Report on Form 10-K for the year ended December 31, 2012, filed with the SEC on February 21, 2013.

	Note 4. Net (Loss) Income Per Share
	Basic net (loss) income per common share is calculated by dividing net (loss) income by the weighted average number of common shares outstanding during the reporting period. Diluted net (loss) income per share is calculated based on the weighted average number of common shares and dilutive potential common shares outstanding during the period. Dilutive potential common shares consist of the shares issuable upon the exercise of stock options and upon the vesting of restricted stock awards under the treasury stock method. In net loss periods, basic net loss per share and diluted net loss per share are identical since the effect of potential common shares is anti-dilutive and therefore excluded.

	In August 2008, our Board of Directors authorized a program to repurchase shares of our common stock having an aggregate value of up to $8.0 million. As of September 30, 2013, we had approximately $3.6 million remaining under this authorization. The authorization allows us to repurchase our common stock from time to time through open market purchases and negotiated transactions, or otherwise. The timing, nature and amount of such transactions will depend on a variety of factors, including market conditions, and the program may be suspended, discontinued or accelerated at any time. The sources of funds for the purchases under the remaining authorization are our existing cash on hand and cash from operations. Purchases are made in the open market, through block trades and other negotiated transactions. Repurchased shares are held in Treasury Stock and have not been retired.  The Company did not repurchase any shares during either the three or nine months ended September 30, 2013, or 2012.
	The Company withheld approximately 9,000 and 209,000, and 10,000 and 142,000 common shares for the three and nine months ended September 30, 2013 and 2012, respectively, from employees to satisfy their personal income tax withholding requirements upon the vesting of restricted stock awards issued under our equity compensation plans. The Company may engage in similar transactions from time to time related to future vesting of employee restricted stock awards. See Part II.

	Note 8. Debt Obligations
	On July 12, 2012, we entered into a Loan and Security Agreement (as amended or supplemented from time to time, the “Loan Agreement”) with a bank.  The Loan Agreement created a line of credit to provide for one or more revolving loans, non-revolving loans or term loans and up to $3.0 million in standby letters of credit (the “Loans”).  The maximum principal amount of Loans that may be outstanding at any given time under the Loan Agreement, including standby letters of credit, is $7.0 million.  Any borrowings under the Loan Agreement would be collateralized by substantially all our assets.  The Loan Agreement requires, among other things, that we remain in compliance with certain financial covenants, including that we maintain unrestricted cash and marketable securities of not less than $12.5 million, that we maintain a ratio of total funded indebtedness to trailing twelve-month earnings before interest, taxes, depreciation, amortization and stock compensation expense (“EBITDA”) of not greater than 2.25 to 1, that we maintain a ratio of cash flow to current portion of long-term debt of not less than 1.25 to 1, and that we shall not allow a cumulative net loss (defined as GAAP net loss before non-cash stock compensation expense and amortization of intangibles) of more than $5.0 million during any fiscal year.  Borrowings under the Loan Agreement bear interest at one of the following rates (as selected by us): a rate equal to the bank’s alternate base rate plus 1.00% or LIBOR plus 2.25%. All principal, interest and other amounts owing under the Loan Agreement will be due and payable in full on or prior to June 30, 2014.
	As of June 30, 2013, the Company was not in compliance with the covenant that requires the Company to not exceed a cumulative loss of $5.0 million during any fiscal year.  On October 31, 2013, we received a one-time waiver from the bank for the breach of this covenant.
	On October 31, 2013 we entered into a modification agreement (“Modification Agreement”) of the Loan Agreement with the bank to modify certain financial covenants pertaining to the Loan Agreement. Under the Modification Agreement the financial covenant that requires that we maintain unrestricted cash and marketable securities of not less than $12.5 million, as measured at each fiscal quarter end, is changed to $15.0 million for the period commencing July 1, 2013 through June 30, 2014, and $12.5 million at each fiscal quarter end thereafter. In addition, the financial covenant that requires that we shall not allow a year-to-date net loss in excess of $5.0 million during any fiscal year is changed to $11.8 million at September 30, 2013, $13.2 million at December 31, 2013 and $5.0 million thereafter.
	After considering the terms of the Modification Agreement, as of September 30, 2013, we were in compliance with all the covenants from the Loan Agreement and the Modification Agreement.  We have letters of credit outstanding against the line in the amount of $1.8 million as of September 30, 2013, and as of that date there were no other borrowing outstanding, resulting in available borrowing under the Loan Agreement of $5.2 million.

	At September 30, 2013, approximately 1,660,000 shares were available for grant as options or nonvested share awards under the Guidance Software, Inc. Second Amended and Restated 2004 Equity Incentive Plan (the “Plan”).
	Stock Options
	The terms of the options granted under the Plan are determined at the time of grant, and generally vest 25% annually over a four-year service period and typically must be exercised within 10 years from the date of grant.

	We define in-the-money options at September 30, 2013 as options that had exercise prices that were lower than the $9.07 fair market value of our common stock at that date. The aggregate intrinsic value of options outstanding at September 30, 2013 is calculated as the difference between the exercise price of the underlying options and the fair market value of our common stock for the 4,438,000 shares that were in-the-money at that date, of which 853,000 were exercisable.
	Restricted Stock Awards
	We issue restricted stock awards to certain directors, officers and employees. Compensation expense for such awards, based on the fair market value of the awards on the grant date, is recorded during the vesting period.  Restricted stock awards generally vest 25% annually over a four-year service period.

	We account for share-based compensation in accordance with Compensation-Stock Compensation (ASC 718). The Company uses the Black-Scholes option pricing model to determine the fair value of stock options on the grant date.  The Company determines the fair value of its restricted stock grants as the market value on the date of grant.  We recognize the cost, net of an estimated forfeiture rate, as compensation expense on a straight-line basis over the vesting period. We estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. We recognize share-based compensation on a straight-line basis over the requisite service period of the awards, which is generally the vesting period.
	The following table summarizes the share-based compensation expense we recorded (in thousands):

	Note 11. Income Taxes
	We account for income taxes in accordance with Income Taxes (ASC 740). Deferred income taxes are recorded for the expected tax consequences of temporary differences between the tax bases of assets and liabilities for financial reporting purposes and amounts recognized for income tax purposes. We record a valuation allowance to reduce our deferred tax assets to the amount of future tax benefit that is more likely than not to be realized. As of September 30, 2013, we have recorded a valuation allowance against our net deferred tax assets resulting in a carrying value of zero.
	In accordance with ASC 740, the valuation allowance for a particular tax jurisdiction is allocated between current and non-current deferred tax assets for that tax jurisdiction on a pro-rata basis.  For the year ended December 31, 2012, the Company previously netted its valuation allowance in total against net deferred tax assets.  The Company has revised the presentation of the valuation allowance for the year ended December 31, 2012 to show the allocation of the valuation allowance to the current and non-current deferred tax assets.  The total impact was an increase to current deferred tax assets and an increase to non-current deferred tax liabilities of $647,000 for the year ended December 31, 2012.
	Management’s judgment is required in assessing the realizability of future deferred tax assets. We consider all available evidence, both positive and negative, including historical levels of income, expectations and risks associated with estimates of future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for a valuation allowance. If we later determine that it is more likely than not that the net deferred tax assets would be realized, we would reverse the applicable portion of the previously provided valuation allowance. Likewise, in the event we were to determine that we would not be able to realize all or part of our net deferred tax assets in the future, an adjustment to the deferred tax assets would be charged to earnings in the period in which we make such a determination.
	We file income tax returns with the Internal Revenue Service and the taxing authorities of various state and foreign jurisdictions. We periodically perform a review of our uncertain tax positions. An uncertain tax position represents our expected treatment of a tax position taken in a filed tax return, or planned to be taken in a future tax return, that has not been reflected in measuring income tax expense for financial reporting purposes.  At September 30, 2013, our liability for uncertain tax positions was $0.5 million. We do not expect there to be any material changes to the estimated amount of liability associated with our uncertain tax positions over the next twelve months. The tax years 2009 through 2011 remain subject to review by the taxing authorities in several jurisdictions. Most foreign jurisdictions have statute of limitations that range from three to six years.

	Note 12. Fair Value Measurements
	In accordance with Fair Value Measurements and Disclosures (ASC 820) we measure our financial assets and liabilities at fair value on a recurring basis. Fair Value Measurements and Disclosures (ASC 820) requires disclosure that establishes a framework for measuring fair value and expands disclosure about fair value measurements. Under this standard, fair value is defined as the price that would be received in exchange for selling an asset or paid to transfer a liability (i.e., the “exit price”) in an orderly transaction between market participants at the measurement date. Fair Value Measurements and Disclosures (ASC 820) establishes a hierarchy for inputs used in measuring fair value that minimizes the use of unobservable inputs by requiring the use of observable market data when available. Observable inputs are inputs that market participants would use in pricing the asset or liability based on active market data. Unobservable inputs would be inputs that reflect our assumptions about the assumptions market participants would use in pricing the asset or liability based on the best information available in the circumstances. The statement requires fair value measurements be classified and disclosed in one of the following three categories:
	Level 1:	Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets and liabilities.
	Level 2:	Quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly, and corroborated by market data.
	Level 3:	Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable.
	The following table sets forth, by level within the fair value hierarchy, financial assets and liabilities that are accounted for at fair value on a recurring basis as of September 30, 2013 and December 31, 2012 (in thousands):

	The Company has obligations, to be paid in cash, to the former shareholders of CaseCentral if certain SaaS and EnCase® eDiscovery revenue thresholds are achieved during the two 12-month periods starting April 1, 2013.  The fair value of this contingent consideration is determined using an expected present value calculation.  Expected cash flows are determined using the probability-weighted average of possible outcomes that would occur should certain revenue metrics be reached.  There are no market data available to use in valuing the contingent consideration; therefore, the Company developed its own assumptions related to the future financial performance of the businesses to evaluate the fair value of these liabilities.  As such, the contingent consideration is classified within Level 3, as described above.
	In connection with estimating the fair value of the contingent consideration, the Company developed various scenarios (base case, downside case, and upside case) and weighted each case according to the probability of occurrence. The probabilities ranged from 20 percent to 50 percent, with the most significant weighting given to the base case at 50 percent. These scenarios were developed based on the expected financial performance of CaseCentral, with SaaS revenue growth rates being a primary input in the calculation. An increase or decrease in the probability of achievement of any of the scenarios could result in a significant increase or decrease to the estimated fair value.
	The fair value is reviewed quarterly based on the financial performance of the most recently completed fiscal quarter. An analysis is performed at the end of each fiscal quarter to compare actual results to forecasted financial performance. If performance has deviated from projected levels, the valuation is updated for the latest information available.
	The significant assumptions that may materially affect fair value are developed in conjunction with the guidance of our senior management to ensure that the most accurate and latest financial projections are used and compared with the most recent financial results in the fair value measurement.

	Legal Matters
	On May 20, 2011, MyKey Technology Inc. (“MyKey”) filed a complaint against us and certain other parties for patent infringement in the United States District Court for the District of Delaware.  With respect to the Company, the complaint alleged that certain of our data acquisition forensic hardware products that we acquired as a result of our acquisition of certain assets of Tableau, LLC, (“Tableau”) infringe three of MyKey’s patents relating to write blocking, duplication and data removal technologies, respectively.  The complaint sought a declaration of infringement, a finding of willful infringement, compensatory damages, treble damages, injunctive relief, interest, expenses, costs and attorneys’ fees.
	On July 22, 2011, MyKey also filed a complaint with the United States International Trade Commission (the “ITC”), alleging infringement by the Company and certain other parties of the three patents discussed in the preceding paragraph and requesting that the ITC commence an investigation pursuant to Section 337 of the Tariff Act of 1930.  The complaint sought injunctive relief barring the Company from the importation of products that allegedly infringed the three patents of MyKey.  On August 24, 2011, the ITC commenced an investigation of the Company and certain other parties related to the complaint by MyKey. On August 31, 2011 the proceeding in the District Court was stayed pending the resolution of the ITC matter.  On August 1, 2012, MyKey amended its ITC complaint to remove allegations that its duplication patent had been infringed by the Company and to reduce the number of claims it alleges the Company has infringed related to MyKey’s data removal patent.  In August 2012, the parties completed the ITC trial on the remaining patent claims at issue.
	On December 28, 2012, the ITC released a final determination and Order holding that no violation of Section 337 of the Tariff Act of 1930 occurred as a result of the Company’s importation into the United States and sale of the products at issue.  This Order effectively ended the ITC proceeding.  On February 20, 2013, the U.S. District Court of Delaware lifted the stay of the proceedings in the MyKey matter.
	Effective April 8, 2013, the parties stipulated to a transfer of the matter to the U.S. District Court for the Central District of California.  On April 16, 2013, the Company filed its Answer and Counterclaim.  MyKey filed a petition to consolidate a number of related cases, including the case against the Company in the Central District of California, into a Multi-District Litigation (“MDL”) proceeding.   On August 16, 2013, the MDL panel approved the petition and assigned the MDL consolidated case to the judge who is also presiding over the individual case against the Company.  The MDL case will dispose of certain issues common to the consolidated cases.
	We intend to defend the ongoing MyKey matter vigorously and, at this time, are unable to estimate what, if any, liability we may have in connection with these matters.  We are unable to estimate a range of reasonably possible losses due to various reasons, including, among others, that (1) certain of the proceedings are at an early stage, (2) there is uncertainty as to the outcome of pending appeals, motions, or settlements, (3) there are significant factual issues to be resolved, (4) there are unresolved negotiations with certain indemnitors or indemnitees of the Company, related to the actions, and (5) we have meritorious defenses that we intend to assert.
	From time to time, we may become involved in various other lawsuits and legal proceedings that arise in the ordinary course of business. Litigation is subject to inherent uncertainties, and an adverse result in these or other matters may arise from time to time that may harm our business. We are not currently aware of any such other legal proceedings or claims that are likely to have a material impact on our business.
	Indemnifications
	We have agreed to indemnify our directors and executive officers for costs associated with any fees, expenses, judgments, fines and settlement amounts incurred by them in any action or proceeding to which any of them is, or is threatened to be, made a party by reason of his or her services in their role as a director or officer.

Segment Information	'
	Note 16. Segment Information
	We have adopted Segment Reporting (ASC 280) requiring segmentation based on our internal organization and reporting of revenue and other performance measures. Our segments are designed to allocate resources internally and provide a framework to determine management responsibility. Operating segments are defined as components of an enterprise about which discrete financial information is available that is evaluated regularly by the chief operating decision maker, or decision making group, in deciding how to allocate resources and in assessing performance. Our chief operating decision maker is our Chief Executive Officer. We have five operating segments, as summarized below:
	·                  Products segment—Includes EnCase® Enterprise, EnCase® eDiscovery, EnCase® Analytics, EnCase® Cybersecurity, EnCase® Forensic, EnCase® Portable, Premium License Support Program and hardware sales.
	·                  Subscription segment—Includes subscription services for cloud-based document review and production software.  The subscription segment is new as of February 2012 due to our acquisition of CaseCentral.
	·                  Professional services segment—Performs consulting services and implementations.
	·                  Training segment—Provides training classes by which we train our customers to effectively and efficiently use our software products.
	·                  Maintenance segment—Includes maintenance related revenues.
	We present the revenues generated by our services and maintenance segments collectively. Currently, we do not separately allocate operating expenses to these segments, nor do we allocate specific assets, with the exception of goodwill, to these segments. Therefore, the segment information reported includes only revenues, cost of revenues and segment profit. The following tables present the results of operations for each operating segment (in thousands):

Basis of Presentation	'
	Basis of Presentation
	The accompanying condensed consolidated balance sheets as of September 30, 2013 and the condensed consolidated statements of operations for the three and nine months ended September 30, 2013 and 2012 and cash flows for the nine months ended September 30, 2013 and 2012 are unaudited. These statements should be read in conjunction with the audited consolidated financial statements and related notes, together with management’s discussion and analysis of financial position and results of operations, contained in our Annual Report on Form 10-K for the year ended December 31, 2012, filed with the U.S. Securities and Exchange Commission (the “SEC”) on February 21, 2013. The operating results for the three and nine month periods ended September 30, 2013 and cash flows for the nine month period ended September 30, 2013 are not necessarily indicative of the results that will be achieved for the full fiscal year or for future periods.
	The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States, or (“GAAP”), and pursuant to the rules and regulations of the SEC for interim financial reporting. In the opinion of our management, the unaudited condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2012 and include all adjustments necessary for the fair presentation of our financial position as of September 30, 2013 and our results of operations for the three and nine months ended September 30, 2013 and 2012 and our cash flows for the nine month period ended September 30, 2013 and 2012. The condensed consolidated balance sheet as of December 31, 2012 has been derived from the December 31, 2012 audited financial statements. The interim financial information contained in this Quarterly Report is not necessarily indicative of the results to be expected for any other interim period or for the entire year.
	The condensed consolidated financial statements include the accounts of Guidance and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.
	The Company’s restricted stock award agreements provide that holders of the restricted stock awards shall have all the rights of a stockholder upon the grant date, including the right to vote as a stockholder.  As such, these shares are considered issued and outstanding on the date of grant. As of December 31, 2012, the Company previously excluded unvested restricted stock awards from the presented quantity of common shares issued and outstanding. The Company has increased the number of common shares issued and outstanding by 2,511,000 as of December 31, 2012 to reflect these unvested restricted stock awards.
Use of Estimates and Assumptions	'
	Use of Estimates and Assumptions
	The preparation of financial statements in conformity with GAAP requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate these estimates, including those related to revenue recognition, share-based compensation, bad debts, income taxes, contingent consideration, commitments, contingencies and litigation. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results may differ from these estimates.
Cash and Cash Equivalents	'
	Cash and Cash Equivalents
	We invest excess cash in money market funds and highly liquid debt instruments of the US government and its agencies. Highly liquid investments with stated maturities of three months or less from the date of purchase are classified as cash and cash equivalents.
Fair Value of Financial Instruments	'
	Fair Value of Financial Instruments
	The carrying amounts of cash equivalents, accounts receivable and accounts payable approximate fair value because of the short-term maturities of these instruments. Based on borrowing rates currently available to us for borrowings with similar terms, the carrying values of our capital lease obligations also approximate fair value.
Trade Receivables	'
	Trade Receivables
	Trade receivables are carried at original invoice amount less an allowance for doubtful accounts. The allowance is established through a provision for bad debt expense, which is included in general and administrative expenses. We determine the adequacy of this allowance by evaluating individual customer accounts receivable, through consideration of the customer’s financial condition, credit history and current economic conditions. In addition, we analyze our historical credit loss history and apply these loss rates to our current accounts receivable balances to verify the reasonableness of our allowance. Trade receivables are written off when deemed uncollectible. A trade receivable is generally considered past due if any portion of the receivable balance is outstanding for more than 30 days unless alternate terms are provided.
Inventory	'
	Inventory
	Inventory is comprised of hardware components, packaged software components and finished goods and is valued at the lower of cost or market, using the weighted average cost method. We conduct quarterly inventory reviews for obsolescence, and inventory considered unlikely to be sold is adjusted to net realizable value.
Business Combinations	'
	Business Combinations
	The purchase price of an acquisition is allocated to the underlying assets acquired and liabilities assumed based upon their estimated fair values at the date of acquisition. To the extent the purchase price exceeds the fair value of the net identifiable tangible and intangible assets acquired and liabilities assumed, such excess is allocated to goodwill. We determine the estimated fair values after review and consideration of relevant information including discounted cash flows, quoted market prices and estimates made by management. Accordingly, these can be affected by certain performance measurements and other factors over time, which may cause final amounts to differ materially from original estimates. We adjust the preliminary purchase price allocation, as necessary, up to periods of one year after the acquisition closing date as we obtain more information regarding asset valuations and liabilities assumed.  We refer to this preliminary purchase price allocation period as the measurement period.
	Goodwill acquired in business combinations is assigned to the reporting unit(s) expected to benefit from the combination as of the acquisition date.  Acquisition related costs are recognized separately from the acquisition and are expensed as incurred.
Amortization of Intangible Assets with Finite Lives	'
	Amortization of Intangible Assets with Finite Lives
	Intangible assets with finite lives are recorded at their fair value at the time of acquisition.  With the exception of our customer relationships intangible asset, which is amortized on a double-declining basis, the acquisition date fair values of such assets are amortized on a straight-line basis over the estimated useful lives.
Goodwill and Indefinite-Lived Intangibles	'
	Goodwill and Indefinite-Lived Intangibles
	Goodwill represents the excess of purchase price over fair value of net assets acquired and is assigned to a reporting unit at the date the goodwill is initially recorded. Goodwill and indefinite-lived intangible assets are not amortized but evaluated for impairment annually, or whenever events or changes in circumstances indicate that the value may not be recoverable.  Commencing on January 1, 2013, the Company adopted the ASU 2011-08 issued by the Financial Accounting Standards Board (“FASB”) for the revised guidance on “Testing of Goodwill for Impairment.”  Under this guidance, the Company has the option to choose whether it will apply the qualitative assessment first before the quantitative assessment.  If a quantitative assessment is necessary a two-step test is performed at the reporting unit level to assess goodwill for impairment. First, the fair value of the reporting unit is compared to its carrying value. If the fair value exceeds the carrying value, the reporting unit is not impaired and no further testing is performed. The second step is performed if the carrying value exceeds the fair value. If the carrying value of the reporting unit exceeds its implied fair value, an impairment loss equal to the difference will be recorded. Indefinite-lived intangible assets are assessed for impairment by comparing the carrying value of the assets with their fair values.
	Application of the impairment test requires significant judgment to estimate the fair value. Changes in estimates and assumptions could materially affect the determination of fair value and/or impairment.
Concentrations of Credit Risk	'
	Concentrations of Credit Risk
	Financial instruments that potentially subject us to significant concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. We restrict our investments in cash and cash equivalents to financial institutions, US government or federal agency instruments and obligations of corporations with high credit ratings. At September 30, 2013, the majority of our cash balances were held at financial institutions located in California in accounts that are insured by the Federal Deposit Insurance Corporation for up to $250,000. Uninsured balances aggregate approximately $16.2 million as of September 30, 2013.  At September 30, 2013, all of our cash equivalents consisted of financial institution obligations. We periodically perform credit evaluations of our customers and maintain reserves for potential losses on our accounts receivable. We do not believe we are subject to concentrations of credit risk with respect to such receivables.
Revenue Recognition	'
	Revenue Recognition
	We generate revenues principally from the sale of EnCase®Enterprise and EnCase® Forensic software products.  Revenues associated with the sale of software licenses and revenues associated with forensic hardware sales are referred to as product revenues.  Following the acquisition of CaseCentral, Inc. (“CaseCentral”) in February 2012, we have revenue associated with cloud-based document review and production SaaS, which is referred to as subscription revenues.  Revenues are also generated from training courses, implementation services and consulting services in which we assist customers with the performance of digital investigations and train their IT and legal professionals in the use of our software products, which we collectively refer to as services revenues.  Our proprietary products are generally sold with one to three years of maintenance, which can be renewed at a stated renewal rate and is referred to as maintenance revenues.
	We recognize revenue in accordance with Accounting Standards Update (“ASU”) 2009-13, Multiple-Deliverable Revenue Arrangements, (amendment to Accounting Standards Codification (“ASC”) Topic 605, Revenue Recognition), Software Industry-Revenue Recognition topic (ASC 985-605) and Revenue Recognition (ASC 605).  While the standards govern the basis for revenue recognition, significant judgment and the use of estimates are required in connection with the allocation of revenues between product, subscription, services and maintenance revenues, as well as the amount of deferred revenues to be recognized in each accounting period.
	Revenue Recognition Criteria. In general, we recognized revenue when the following criteria have been met:
	·                  Persuasive evidence of an arrangement: If we either enter into contracts or receive written purchase orders issued by a customer that legally bind us and the customer, we consider that as evidence of an arrangement.
	·                  Delivery: We deem delivery of a product to have occurred when the title and risk of ownership have passed to the buyer. Services revenues are recognized as delivered.
	·                  Fixed or determinable fee: We consider the fee to be fixed or determinable if the fee is not subject to refund or adjustment and the payment terms are within normal established practices. If the fee is not fixed or determinable, we recognize revenues as amounts become due and payable provided all other revenue recognition criteria have been met.
	·                  Collection is deemed probable: We conduct a credit review for all significant transactions at the time of the arrangement to determine the credit-worthiness of the customer. Collection is deemed probable if we have a reasonable basis to expect that a customer will pay amounts due under an arrangement as they become due.
	Revenue Recognition for Software Products and Software-Related Services (Software Elements)
	Software product revenues.  The timing of software product revenues recognition is dependent on the nature of the product sold. We do not have any product offerings where software components and non-software components function together to deliver the tangible product’s essential functionality.
	EnCase® Enterprise Solutions and EnCase® Forensic Solutions: Revenues associated with these arrangements, exclusive of amounts allocated to maintenance and other undelivered elements, for which we have vendor-specific objective evidence of fair value (“VSOE”), is recognized upon delivery, provided that all other criteria for revenue recognition have been met.  Revenues associated with term licenses are recognized ratably over the term of the license.
	Services and maintenance revenues. The majority of our consulting and implementation services are performed under per hour, or fixed fee arrangements. Revenues from such services are recognized as the services are provided or upon expiration of the contractual service period.
	Training revenues are either recognized on a per-class basis upon a participant’s attendance or, for those customers who have subscribed to our Annual Training Passport program, revenues are recognized ratably over the annual period.
	Revenues related to technical support and software updates on a when-and-if available basis is referred to as maintenance revenues. We recognize maintenance revenues ratably over the applicable maintenance period. We determine the amount of maintenance revenues to be deferred through reference to substantive maintenance renewal provisions contained in multiple element arrangements. We consider substantive maintenance provisions to be provisions where the cost of the maintenance renewal, stated in the contract with our customer as a percentage of the product fee, is comparable to the normal pricing for maintenance only renewals.
	Revenue Recognition for Multiple-Element Arrangements — Software Products and Software-Related Services (Software Arrangements)
	We often enter into arrangements with customers that purchase both software products and software-related services from us at the same time, or within close proximity of one another (referred to as software-related multiple-element arrangements).  Such software-related multiple-element arrangements may include the sale of our software products, software maintenance services, which includes license updates and product support, consulting/implementation services and training whereby the software license delivery is followed by the subsequent delivery of the other elements.  For those software-related multiple-element arrangements, we have applied the residual method to determine the amount of software license revenues to be recognized pursuant to ASC 985-605.  Under the residual method, if VSOE exists for the undelivered elements, this amount is deferred with the remaining, or residual, portion of the arrangement consideration recognized upon delivery of the software license, provided all other revenue recognition criteria are met.
	Revenue Recognition for Hardware and Subscription (SaaS) Revenues (Nonsoftware Elements)
	Hardware product revenues. Revenues associated with the sale of forensic hardware is recognized upon shipment to the customers which include certain resellers, provide that all other criteria for revenue recognition have been met.
	Subscription revenues.  Customers pay subscription fees to access our cloud-based document review and production software; however, they may not take possession of the software at any time during the term of the agreement.  In general, we recognize revenues for subscription fees on a straight-line basis over the contract period commencing on the date the subscription is made available to the customer.  Usage-based fees, which are determined monthly, are recognized when incurred.
	Revenue Recognition for Multiple-Element Arrangements — Hardware, SaaS and Nonsoftware-Related Services (Nonsoftware Arrangements)
	We enter into arrangements with customers that purchase both nonsoftware-related SaaS subscription and nonsoftware-related services, such as consulting services, at the same time or within close proximity of one another (referred to as nonsoftware multiple-element arrangements).  Each element within a nonsoftware multiple-element arrangement is accounted for as a separate unit of accounting provided the following criteria are met: the delivered products or services have value to the customer on a standalone basis; and for an arrangement that includes a general right of return relative to the delivered products or services, delivery or performance of the undelivered product or service is considered probable and is substantially controlled by us.  We consider a deliverable to have standalone value if the product or service is sold separately by us or another vendor, or could be resold by the customer.  Further, our revenue arrangements generally do not include a general right of return relative to the delivered products.  Where the aforementioned criteria for a separate unit of accounting are not met, the deliverable is combined with the undelivered element and treated as a single unit of accounting for the purposes of allocation of the arrangement consideration and revenue recognition.  For those units of accounting that include more than one deliverable but are treated as a single unit of accounting, we generally recognize revenues over the delivery period.  For the purposes of revenue classification of the elements that are accounted for as a single unit of accounting, we allocate revenue to the respective revenue line items within our consolidated statements of operations based on a rational and consistent methodology utilizing our best estimate of relative selling prices of such elements.
	For our nonsoftware multiple-element arrangements, we allocate revenue to each element based on a selling price hierarchy at the arrangement’s inception.  The selling price for each element is based upon the following selling price hierarchy:  VSOE, if available; third party evidence (“TPE”) if VSOE is not available; or best estimate of selling price (“BESP”) if neither VSOE nor TPE are available.  A description as to how we determine VSOE, TPE and BESP is provided below:
	·                  VSOE.  VSOE is determined based on its historical pricing and discounting practices for the specific product or service when sold separately.  In determining VSOE, we require that a substantial majority of the selling prices for these services fall within a reasonably narrow pricing range.
	·                  TPE.  When VSOE cannot be established for deliverables in a multiple element arrangement, judgment is applied with respect to whether we can establish a selling price based on TPE.  TPE is determined based on competitor prices for similar deliverables when sold separately.  Generally, our go-to-market strategy differs from that of our peers and our offerings contain a significant level of differentiation such that comparable pricing of services with similar functionality has not been obtained.  Furthermore, we have been unable to reliably determine selling prices of similar competitive services on a stand-alone basis.  As a result, we have not been able to establish selling prices based on TPE.
	·                  BESP.  When VSOE or TPE is unable to be established, we use BESP in our allocation of arrangement consideration.  The objective of BESP is to determine the price at which we would transact a sale if the service were sold on a stand-alone basis.  We determine BESP for deliverables by considering multiple factors including but not limited to prices we charge for similar offerings, market conditions, competitive landscape and pricing practices.
	Revenue Recognition for Multiple-Element Arrangements — Arrangements with Software and Nonsoftware Elements
	We also enter into multiple-element arrangements that may include a combination of our various software-related and nonsoftware-related products and services.  In such arrangements, we first allocate the total arrangement consideration based on the relative selling prices to the software group of elements as a whole and to the nonsoftware group of elements.  We then further allocate consideration with the software group and nonsoftware group to the respective elements within that group following the guidance in ASC 985-605 and our policies described above.  After the arrangement consideration has been allocated to the elements, we recognize revenue for each respective element in the arrangement as described above.
