Summary of Significant Accounting Policies:	'
	1.     Summary of Significant Accounting Policies:
	Description of Business:
	Datalink Corporation provides solutions and services that help make data centers more efficient, manageable and responsive to changing business needs. Focused on midsize and large companies, we help companies migrate from physical to virtual data centers, ensure data protection and optimize enterprise networks. We derive our revenues principally from designing, installing and supporting data center solutions. Our solutions and services span four practices: consolidation and virtualization of data center infrastructures; enhanced data protection; advanced network infrastructures; and business continuity and disaster recovery solutions. We are frequently engaged to consult and provide assistance in the installation of data center solutions and to provide support services subsequent to the installation.
	Recently Issued and Adopted Accounting Standard:
	In July 2013, the FASB issued Accounting Standards Update No. 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists ("ASU No. 2013-11"). ASU No. 2013-11 provides guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. ASU No. 2013-11 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of ASU No. 2013-11 will not have a significant impact on our consolidated financial statements.
	In July 2012, the FASB issued an update to ASC 350: Testing Indefinite-Lived Intangible Assets for Impairment. This update states that an entity has the option first to assess qualitative factors to determine whether the existence of events and circumstances indicates that it is more likely than not that the indefinite-lived intangible asset is impaired. If, after assessing the totality of events and circumstances, an entity concludes that it is not more likely than not that the indefinite-lived intangible asset is impaired, then the entity is not required to take further action. However, if an entity concludes otherwise, then it is required to determine the fair value of the indefinite-lived intangible asset and perform the quantitative impairment test by comparing the fair value with the carrying amount in accordance with ASC 350. Under the guidance in this update, an entity also has the option to bypass the qualitative assessment for any indefinite-lived intangible asset in any period and proceed directly to performing the quantitative impairment test. An entity will be able to resume performing the qualitative assessment in any subsequent period. The amendments to ASC 350 are effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. The adoption of this update did not have a material impact on our financial statements.
	Cash and Cash Equivalents:
	Cash equivalents consist principally of money market funds with original maturities of three months or less, are readily convertible to cash and are stated at cost, which approximates fair value. We maintain our cash in bank deposit and money market accounts which, at times, may exceed federally insured limits. We have not experienced any losses in such accounts.
	Short-Term Investments:
	Our short term investments consist principally of commercial paper and corporate bonds. We categorize these investments as trading securities and record them at fair value. We classify investments with maturities of 90 days or less from the date of purchase as cash equivalents; investments with maturities of greater than 90 days from the date of purchase but less than one year generally as short-term investments; and investments with maturities of greater than one year from the date of purchase generally as long-term investments.
	Accounts Receivable, net:
	We carry accounts receivable at original invoice amount less an estimate made for doubtful receivables based on a review of all outstanding amounts on a monthly basis. Management determines the allowance for doubtful accounts by regularly evaluating individual customer receivables and considering a customer's financial condition and credit history and current economic conditions. We write off accounts receivable when deemed uncollectible, which is generally in excess of a year past due provided we have no additional information to suggest we continue to expect customer payment. We record recoveries of accounts receivable previously written off when received.
	We recorded accounts receivable net of the reserve for doubtful accounts of $331,000 and $223,000 at December 31, 2013 and 2012, respectively.
	Concentration of Credit Risk:
	We had no customers that comprised more than 10% of our net sales in 2013, 2012 or 2011. However, our top five customers collectively accounted for 10%, 11%, and 11% of our 2013, 2012, and 2011 revenues, respectively.
	Inventories:
	Inventories, including inventories shipped but not installed, principally consist of data storage products and components, valued at the lower of cost or market with cost determined on a first-in, first-out (FIFO) method. We reduced inventories for obsolete and slow moving reserves by $89,000 and $310,000 at December 31, 2013 and 2012, respectively.
	Property and Equipment:
	We state property and equipment, including purchased software, at cost. We provide for depreciation and amortization by charges to operations using the straight-line method over the estimated useful lives of the assets (ranging from 2 to 10 years). We amortize leasehold improvements on a straight-line basis over the shorter of their estimated useful lives or the underlying lease term. We remove the costs and related accumulated depreciation and amortization on asset disposals from the accounts and include any gain or loss in operating expenses. We capitalize major renewals and betterments, but charge maintenance and repairs to current operations when incurred.

	Goodwill:
	We assess the carrying amount of our goodwill for potential impairment annually or more frequently if events or a change in circumstances indicate that impairment may have occurred. We have only one operating and reporting unit that earns revenues, incurs expenses and makes available discrete financial information for review by our chief operations decision maker. Accordingly, we complete our goodwill impairment testing on this single reporting unit. Our measurement date is December 31st of each year.
	Testing for goodwill impairment is a two step process. The first step screens for potential impairment. If there is an indication of possible impairment, we must complete the second step to measure the amount of impairment loss, if any. The first step of the goodwill impairment test, used to identify potential impairment, compares the fair value of our market capitalization with the carrying value of our net assets. If our total market capitalization is at or below the carrying value of our net assets, we perform the second step of the goodwill impairment test to measure the amount of impairment loss we record, if any. We consider goodwill impairment test estimates critical due to the amount of goodwill recorded on our balance sheet and the judgment required in determining fair value amounts. At each of December 31, 2013 and 2012, we determined that our goodwill was not impaired.
	Valuation of Long-Lived Assets:
	We perform an impairment test for finite-lived assets and other long-lived assets, such as property and equipment and finite-lived intangible assets, whenever events or changes in circumstances indicate that we may not recover the carrying value of such assets. We recognize impairment based on the difference between the fair value of the asset and its carrying value. We generally measure fair value based on discounted cash flow analyses. For 2013 and 2012, we identified no triggering events that required us to evaluate the impairment of our long-lived assets.
	Stock Compensation Plans:
	We utilize the fair value method of accounting to account for share-based compensation awards. This requires us to measure and recognize in our statements of operations the expense associated with all share-based payment awards made to employees and directors based on estimated fair values. We use the Black-Scholes model to determine the fair value of share-based payment awards. Stock-based compensation expense was $4.0 million, $2.6 million and $2.6 million for 2013, 2012 and 2011, respectively.
	Income Taxes:
	We calculate income taxes using the asset and liability method of accounting for income taxes. Under the liability method, we record deferred income taxes to reflect the tax consequences in future years of temporary differences between the tax bases of assets and liabilities and their financial reporting amounts using enacted tax rates for the years in which we expect these items to affect taxable income. We establish valuation allowances when necessary to reduce deferred tax assets to the amount we expect more likely than not to realize. Income tax expense is the tax payable for the period and the change during the period in deferred tax assets and liabilities.
	Uncertain Tax Positions:
	We utilize a two-step approach to recognizing and measuring uncertain tax positions (tax contingencies). The first step evaluates the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not that we will sustain the position on audit, including resolution of related appeals or litigation processes. The second step measures the tax benefit as the largest amount more than 50% likely of being realized upon ultimate settlement. We include interest and penalties for our tax contingencies in income tax expense. At December 31, 2013 and 2012, we had no unrecognized tax benefits which would affect our effective tax rate if recognized.
	Use of Estimates:
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires our management 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. Significant items subject to estimates and assumptions include the reserve for doubtful accounts, reserve for obsolete and slow moving (excess) inventory and impairment analysis of goodwill and long-lived assets. Actual results could differ from those estimates.
	Advertising Costs:
	Advertising and promotion costs are charged to operations as incurred. Advertising and promotion costs included in sales and marketing expense for 2013, 2012 and 2011 were $683,000, $559,000 and $728,000, respectively.
	Revenue Recognition:
	Product Sales.    We sell software and hardware products on both a "free-standing" basis without any services and as data center solutions bundled with installation and configuration services ("bundled arrangements"). Under either arrangement, we recognize revenue from the sales of products, primarily hardware and essential software, when persuasive evidence of an arrangement exists, shipment has occurred and title has transferred, the sales price is fixed or determinable, and collection of the resulting receivable is reasonably assured. In customer arrangements where a formal acceptance of products is required by the customer, revenue is recognized upon meeting such acceptance criteria.
	Service Sales.    In addition to installation and configuration services provided by us or third party vendors as part of our bundled arrangements, our service sales include postcontract customer support ("PCS") and consulting services. On our balance sheet, deferred revenue relates to service sales for which our customer has paid us or has been invoiced but for which we have not yet performed the applicable services. Revenue from extended service contracts is recognized ratably over the contract term, generally one to three years. Professional services are offered under time and material or fixed fee-based contracts or as part of multiple-element arrangements. Professional services revenue is recognized as services are performed when sold on a stand-alone basis. Our service sales include customer support contracts and consulting services.
	Postcontract Customer Support Contracts.    When we sell hardware and/or software products to our customers, we enter into service contracts with them. These contracts are support service agreements. A majority of the time, our internal support desk first assists the customer by performing an initial technical triage to determine the source of the problem and whether we can direct the customer on how to fix the problem. If we cannot solve the problem, we transfer the customer to the manufacturer or its designated service organization.
	When we do not provide "first call" assistance, usually because the manufacturer has not authorized us to do so, our customers call the manufacturer or its designated service organization directly for both the initial technical triage and any follow-up assistance. If the customer calls us first, we transfer the customer to the third party.
	In both scenarios above, we purchase third party support contracts from the manufacturers for their services. In accordance with our agreements, and consistent with standard industry practice, we prepay the third party based on its "list price" for maintenance on the specific hardware or software products we have sold, less our negotiated discounts with the third party. Terms are generally net 30 days. If we provide the initial "first call" services our discounts off of list price are more substantial. In all cases, we are the primary obligor in the transaction. The customer ultimately holds us responsible for fulfillment of the third party support contracts and we bear credit risk in the event of nonpayment by the customer.
	We report customer support contract revenue on a gross basis as there are sufficient indicators in accumulation that we should be reporting these revenues on a gross basis in accordance with ASC Topic 605-45, Reporting Revenue Gross as a Principle versus Net as an Agent. We usually present quotations for maintenance arrangements to our customers without differentiating as to whether we, or a third party, are providing the service. Accordingly, we are, from our customers' perspectives, the primary obligor on our maintenance arrangements. We directly enter into the agreements with our customers to provide maintenance services. In all cases, we set the price to our customer for the maintenance arrangements, whether or not we provide our first call services, and bill our customers for the maintenance arrangement. We owe various third parties regardless of whether we collect from our customer. We are also contractually obligated to provide or arrange to provide these underlying support services to our customers in the unlikely event that the manufacturer or its designated service organization, fails to perform according to the terms of our contract.
	When we sell a service contract as part of a bundled arrangement, we use vendor specific objective evidence ("VSOE") to allocate revenue to the service contract element. In all cases, we defer revenues and incremental direct costs resulting from obtaining our service contracts and amortize them into operations over the term of the contracts, which are generally twelve months. We defer customer support costs as allowed under ASC Topic 605-10-S99 based on the guidance in ASC Topic 605-20. The deferred costs we capitalize consist of direct and incremental costs we prepay to third parties for direct support to our customers under our contract terms. We defer our customer support contract revenues and their related costs because significant obligations remain after contract execution. For example, we provide routine help desk assistance to our customers and assist them in contacting our vendors for additional support services.
	Consulting Services.    Some of our customers engage us to analyze their existing data center architectures and offer our recommendations. Other customers engage us to assist them on-site with extended data center infrastructure projects, to support their data center environments and to help with long-term data center design challenges. For these types of consulting services that do not include the sale of hardware or software products, we recognize revenues as we perform these services.
	Multiple Element Arrangements. In October 2009, the FASB amended the Accounting Standards Codification ("ASC") as summarized in Accounting Standards Update ("ASU") No. 2009-14, Software (Topic 985): Certain Revenue Arrangements That Include Software Elements, and ASU No. 2009-13, Revenue Recognition (Topic 605): Multiple-Deliverable Revenue Arrangements. ASU 2009-14 amended industry specific revenue accounting guidance for software and software related transactions to exclude from its scope tangible products containing software components and non-software components that function together to deliver the product's essential functionality, or what we refer to as essential software. We also sell non-essential software, which continues to be in the scope of ASC 985-605. ASU 2009-13 amended the accounting for multiple-element arrangements to provide guidance on how the deliverables in an arrangement should be separated and eliminates the use of the residual method. ASU 2009-13 also required an entity to allocate revenue using the relative selling price method.
	ASU 2009-13 establishes a hierarchy of evidence to determine the stand-alone selling price of a deliverable based on VSOE, third-party evidence ("TPE"), and the best estimate of selling price ("BESP"). If VSOE is available, it would be used to determine the selling price of a deliverable. If VSOE is not available, the entity would determine whether TPE is available. If so, TPE must be used to determine the selling price. If TPE is not available, then the BESP would be used.
	In certain instances, we are not able to establish VSOE for all deliverables in an arrangement with multiple elements. This may be due to infrequent sales of each element separately, not pricing products within a narrow range, or only having a limited sales history. We have not consistently established VSOE for any of our products or services, except for PCS.
	When VSOE cannot be established, we attempt to determine the standalone selling price for each element based on TPE. TPE is determined based on competitor prices for similar deliverables when sold separately. Generally, our strategy differs from that of our peers and our offerings contain a significant level of customization and differentiation such that the comparable pricing of products with similar functionality cannot be obtained. Furthermore, we are unable to reliably determine what similar competitor products' selling prices are on a stand-alone basis. Therefore, we are typically not able to determine TPE.
	Since we are typically unable to determine VSOE or TPE, we use BESP in our allocation of the arrangement consideration where VSOE or TPE do not exist. Therefore, revenue from these multiple-element arrangements is allocated based on BESP, except for PCS which is allocated based on VSOE. The objective of BESP is to determine the price at which we would transact a sale if the product or service were sold on a stand-alone basis. BESP is generally used for offerings that are not typically sold on a stand-alone basis or for new or highly customized offerings. We determine BESP for product or service using a cost-plus margin approach. When establishing the methodology used to calculate BESP we also considered multiple factors, including, but not limited to, geographies, market conditions, competitive landscape, internal costs, gross margin objectives and pricing practices. The determination of BESP is made through consultation with and formal approval by management.
	We regularly review VSOE, TPE and BESP and maintain internal controls over the establishment and updates of these estimates. We limit the amount of revenue recognized for delivered elements to the amount that is not contingent on the future delivery of products or services, future performance obligations or subject to customer-specified return or refund privileges.
	We evaluate each deliverable in an arrangement to determine whether they represent a single unit of accounting. The delivered item constitutes a separate unit of accounting when it has stand-alone value and there are no customer-negotiated refunds or return rights for the delivered elements. If the arrangement includes a customer-negotiated refund or return right relative to the delivered item and the delivery and performance of the undelivered item is considered probable and substantially in our control, the delivered element would also constitute a separate unit of accounting. In instances when the aforementioned criteria are not met, the deliverable is combined with the undelivered elements and revenue recognition is determined for the combined unit as a single unit of accounting. Allocation of the consideration is determined at arrangement inception on the basis of each unit's relative selling price.
	Our multiple-element product offerings include networking hardware with embedded software products, professional services, and PCS, which are considered separate units of accounting. For fiscal year 2011 and future periods, pursuant to the guidance in ASU 2009-13, when a sales arrangement contains multiple elements, such as products, essential software, PCS and/or professional services, we will allocate revenues to each element based on the aforementioned selling price hierarchy.
In multiple-element arrangements that include software that is not essential to the functionality of the products, revenue is initially allocated to each separate unit of accounting using the relative selling prices of each of the deliverables in the arrangement based on the aforementioned selling price hierarchy. Since non-essential software deliverables are in the scope of ASC 985-605, VSOE must exist to account for the non-essential software deliverables as separate units of accounting from one another and further allocate the originally allocated non-essential software fee among the individual non-essential software deliverables. Since we were only able to establish VSOE for PCS, the amount allocated to the other non-essential software deliverables would be based on the residual method of allocation using VSOE for PCS. This allocated revenue is recognized once all non-essential software deliverables other than PCS are delivered.
In 2013, we began recognizing revenue on certain new professional service contracts that include milestones using a proportional performance method of revenue recognition. Revenues from these fixed price professional service contracts are recognized as services are performed based on the achievement of specified milestones within the contracts and when the customer acknowledges that such criteria have been satisfied. We invoice our customer on these projects as agreed-upon project milestones are achieved and accepted by the customer. We recognized approximately $1.2 million of services revenues under this method during 2013.
Net Earnings Per Share:
We compute basic net earnings per share using the weighted average number of shares outstanding. Diluted net earnings per share include the effect of common stock equivalents, if any, for each period. Diluted per share amounts assume the conversion, exercise or issuance of all potential common stock instruments unless their effect is anti-dilutive. The following table computes basic and diluted net earnings per share:

Fair Value of Financial Instruments:
Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In determining fair value for assets and liabilities required or permitted to be recorded at fair value, we consider the principal or most advantageous market in which it would transact and the assumptions that market participants would use when pricing the asset or liability. We apply fair value measurements for both financial and nonfinancial assets and liabilities. We have no nonfinancial assets or liabilities that require measurement at fair value on a recurring basis as of December 31, 2013.
The fair value of our financial instruments, including cash and cash equivalents, short-term investments, accounts receivable, accounts payable, line of credit and accrued expenses, approximate cost because of their short maturities.
We use the three-level fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair values. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below:
•
Level 1—Unadjusted quoted prices available in active markets for the identical assets or liabilities at the measurement date.
•
Level 2—Significant other observable inputs available at the measurement date, other than quoted prices included in Level 1, either directly or indirectly.
•
Level 3—Significant unobservable inputs that we cannot corroborate by observable market data and thus reflect the use of significant management judgment. We generally determine these values using pricing models based on assumptions our management believes other market participants would make.
The fair value hierarchy requires the use of observable market data when available. In instances in which the inputs used to measure fair value fall into different levels of the fair value hierarchy, we determine the fair value measurement based on the lowest level input that is significant to the fair value measurement in its entirety. Our assessment of the significance of a particular item to the fair value measurement in its entirety requires judgment, including the consideration of inputs specific to the asset or liability. The following table sets forth, by level within the fair value hierarchy, the accounting of our financial assets and/or liabilities at fair value on a recurring basis according to the valuation techniques we used to determine their fair value(s):
(In thousands)	Total at Fair			Quoted Prices in			Significant Other			Significant

	2.     Acquisitions:
	Strategic Technologies, Inc.
	On October 4, 2012, we purchased substantially all of the assets and liabilities of Strategic Technologies, Inc. ("StraTech") from StraTech and Midas Medici Group Holdings, Inc. ("Midas," parent company of StraTech, and, together with StraTech, the "Sellers"). StraTech is an IT services and solutions firm that shares our focus on optimizing enterprise data centers and IT infrastructure through a common product and services portfolio designed to help customers increase business agility. We purchased StraTech for a purchase price of approximately $11.9 million, comprised of a cash payment of approximately $13.2 million, which is offset by a receivable due from the Sellers of approximately $3.3 million, resulting from the preliminary tangible net asset adjustment as defined by the asset purchase agreement. In addition, we issued 269,783 shares of our common stock with a value of approximately $2.0 million. Of those shares, 242,805 shares were deposited in an escrow account as security for certain indemnification obligations of the Sellers.
	Pursuant to the asset purchase agreement, Sellers were obligated to pay us an amount equal to the difference between the actual tangible net assets on the closing date and the Sellers' good faith estimated net tangible assets as set forth in the asset purchase agreement. We initially recorded a receivable due from Sellers of approximately $4.2 million related to this payment at the acquisition date. The Sellers provided us with a "Notice of Disagreement," which stated that they disputed the amount owed to us in connection with this reconciliation payment. The asset purchase agreement contained an arbitration provision for disputes over the value of tangible net assets. During the measurement period (up to one year from the acquisition date), the final tangible net asset adjustment was agreed to and the net effect was a decrease in the receivable due from Sellers of $936,000 and an increase in the purchase price for the same amount as reflected above.
	We estimated the fair value of the assets acquired and liabilities assumed of StraTech primarily using a discounted cash flow approach with respect to identified intangible assets and goodwill. We based this approach upon our estimates of future cash flows from the acquired assets and liabilities and utilized a discount rate consistent with the inherent risk associated with the acquired assets and liabilities assumed. As of December 31, 2012, the fair value of the acquired assets was provisional as we had not yet finalized net working capital adjustments that are included within the "Notice of Disagreement" discussed above. The total purchase price has been allocated to StraTech's net tangible and identifiable intangible assets based on their estimated fair values as of October 4, 2012, and has been adjusted through the measurement period (up to one year from the acquisition date). Adjustments to provisional amounts during the measurement period that were the result of information that existed as of the acquisitions date require the revision of comparative prior period financial information when reissued in subsequent financial statements. Accordingly, our 2012 balance sheet has been retroactively adjusted to account for those changes. The changes did not impact our Statement of Operations.
	The following table summarizes the final allocation of the purchase price including measurement period adjustments:
		(in thousands)
	Assets acquired at their fair value:
	Accounts receivable, net	$	9,539
	Deferred revenue costs		8,521
	Equipment		432
	Finite-lived intangibles		15,920
	Goodwill		5,334
	Other assets		628
	Total assets acquired		40,374
	Liabilities assumed at their fair value:
	Accounts payable		17,599
	Deferred revenue		10,289
	Accrued expenses		567
	Other liabilities		29
	Total liabilities assumed		28,484
	Net purchase price	$	11,890
	The fair value of the assets acquired included a finite-lived intangible asset consisting of customer relationships that have an estimated life of five years and an indefinite-lived asset consisting of goodwill of approximately $5.0 million which will be deductible for tax purposes over a 15-year period. We are amortizing the finite-lived intangible asset we acquired in the StraTech acquisition over its useful life using an accelerated amortization method, to match the pattern in which the economic benefits of that asset are expected to be consumed. We paid a premium over the fair value of the net tangible and identified intangible assets acquired (i.e. goodwill) because this acquisition expanded our market share and physical presence across the Eastern seaboard of the United States and allows us to diversify our product offerings from certain manufacturers and expand our high-margin professional and managed services business lines. We expect to experience operational synergies and efficiencies through combined general and administrative corporate functions.
	The following table provides a reconciliation of the net purchase price for StraTech as compared to the cash payment for purchase:
		(in thousands)
	Payment in cash for purchase	$	13,172
	Less receivable due from seller		(3,307	)
	Plus value of shares issued		2,025
	Net purchase price	$	11,890
	Integration costs for 2013 and 2012 include salaries, benefits and retention bonuses of exiting employees, some of whom assisted with the initial integration of StraTech. In addition, transaction costs for 2012 include legal, audit and other outside service fees necessary to complete our acquisition of StraTech, which were expensed. Total integration and transaction costs were $95,000 and $359,000 during 2013 and 2012, respectively.
	In January 2014, we reached a settlement agreement with the former owners of StraTech regarding the disputed amount owed to us in connection with the reconciliation payment mentioned above. Under the terms of the agreement, the former owners of StraTech agreed to release the entire 242,805 shares of Datalink common stock that were being held in escrow in exchange for a payment of $100,000 and the release of certain other claims. As of December 31, 2013, the remaining $3.3 million receivable due from the Sellers was deemed to be uncollectible and written down to the estimated realizable value, which is the fair value of the shares in escrow on December 31, 2013. The remaining receivable of $2,647,000 was reclassified from accounts receivable to equity within the December 31, 2013 balance sheet. The results for 2013 include a $611,000 charge for the write-down of the account receivable due from the Sellers to the fair value of the stock on December 31, 2013 and reported as a non-operating expense on the statement of operations. Based on the value of our common stock on the date of the settlement agreement in January 2014, we will record a gain before tax of approximately $877,000 during the first quarter of 2014 as a result of the increase in our stock price from December 31, 2013 to the date we repossessed the shares in escrow.
	Midwave Corporation
	In October 2011, we entered into an asset purchase agreement with Midwave Corporation ("Midwave") and its shareholders. Under the asset purchase agreement we purchased and acquired from Midwave substantially all of the assets used in Midwave's business. Midwave is an information technology consulting firm that offers both professional services and sells products to business' information technology organizations utilizing the product portfolios of certain information technology manufacturers, in the specific domains of data center services, networking services, managed services and advisory services. We paid a purchase price of approximately $19.1 million, comprised of a cash payment of approximately $16.1 million and issued 220,988 shares of our common stock with a value of approximately $1.6 million delivered at closing and approximately $1.4 million related to working capital adjustments subsequent to closing.
	We estimated the fair value of the assets acquired and liabilities assumed of Midwave primarily using a discounted cash flow approach with respect to identified intangible assets and goodwill. We based this approach upon our estimates of future cash flows from the acquired assets and liabilities and utilized a discount rate consistent with the inherent risk associated with the acquired assets and liabilities assumed.
	The fair value of the assets acquired included finite-lived intangible assets, which consisted of covenants not to compete, order backlog and customer relationships having estimated lives of three years, three months and five years, respectively, and goodwill of approximately $9.3 million which will be deductible for tax purposes over a 15-year period. We paid a premium over the fair value of the net tangible and identified intangible assets acquired (i.e. goodwill), because we believe this acquisition makes us the dominant data center services and infrastructure provider in Minnesota. We also believe this acquisition doubles our Cisco technology and services revenue, expands our managed services portfolio, adds an established security practice and doubles the size of our consulting services team. We have begun to realize operational synergies and efficiencies through combined general and administrative and corporate functions in 2012.
	The following table summarizes the allocation of the purchase price to the fair value of the assets and liabilities acquired:
		(in thousands)
	Assets acquired at their fair value:
	Accounts receivable, net	$	11,575
	Deferred revenue costs		33

In addition, transaction costs for 2011 include legal, audit and other outside service fees necessary to complete our acquisition of Midwave, which were expensed. Total integration and transaction costs were $454,000 during 2011. We recognized no integration and transactions costs related to the Midwave acquisition during 2012 and 2013.

	In assessing the recoverability of deferred tax assets, management considers whether it is more likely than not that we will realize some portion or all of the deferred tax assets. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. As of December 31, 2013, we have no federal net operating carryforwards. As of December 31, 2013, we have state net operating loss carryforwards of approximately $820,000, which are available to offset future state taxable income. If not used, the state net operating loss carryforwards will expire between 2014 and 2028. For 2013 we recorded approximately $885,000 to equity for tax expenses associated with the exercise of stock options. For 2012 we recorded approximately $781,000 to equity for tax expenses associated with the exercise of stock options. In future periods of taxable earnings, we expect to report an income tax provision using an effective tax rate of approximately 40% to 42%.
	The tax years 2008-2012 remain open to examination by both the Federal government and by other major income taxing jurisdictions to which we are subject.
	Our ability to utilize a portion of our net operating loss carryforwards to offset future taxable income may be subject to certain limitations under Section 382 of the Internal Revenue Code due to changes in our equity ownership. We do not believe that an ownership change under Section 382 has occurred, and therefore, no such limitations exist.

In December 2011, we entered into a First Amendment to Lease (the "Amendment") to the Original Lease for approximately 32,906 additional square feet of office space ("Expansion Space"), which provides us with approximately 54,000 total square feet available for our operations. We moved our corporate headquarters to this new location in April 2012. Under the terms of the Amendment, the term of the Original Lease was extended for 42 months from March 1, 2016 through August 31, 2019 and the term of the lease for the Expansion Space is for seven years and six months, which commenced on March 1, 2012.

	8.     Line of Credit:
	On July 17, 2013, we entered into a credit agreement with Castle Pines Capital LLC ("CPC"), an affiliate of Wells Fargo Bank, National Association. The credit agreement provides for a floor plan line of credit and a revolving facility in a maximum combined aggregate amount of $40 million. Borrowing under the revolving facility cannot exceed the lesser of (i) $40 million minus the amount outstanding under the floor plan line of credit or (ii) a borrowing base consisting of 85% of certain eligible accounts and 100% of channel financed inventory, subject to CPC's ability to impose reserves in the future. The floor plan line of credit finances certain purchases of inventory by us from vendors approved by CPC and the revolving facility is used for working capital purposes and permitted acquisitions.
	The amounts outstanding under the revolving facility will bear interest at a per annum rate of 2.0% above Wells Fargo's one-month LIBOR rate (approximately 0.17% at December 31, 2013). Advances under the floor plan line of credit will not bear interest so long as they are paid by the applicable payment due date and advances that remain outstanding after the applicable payment due date will bear interest at a per annum rate of LIBOR plus 4%. We are obligated to pay quarterly to CPC an unused commitment fee equal to 0.50% per annum on the average daily unused amount of the combined facility, with usage including the sum of any advances under either the floor plan line of credit or the revolving facility. The combined facility and certain bank product obligations owed to Wells Fargo and CPC or its affiliates are secured by substantially all of our assets. The credit agreement terminates on July 17, 2016 and we will be obligated to pay certain prepayment fees if the credit agreement is terminated prior to that date.
	The credit agreement contains customary representations, warranties, covenants and events of default, including but not limited to, covenants restricting our ability to (i) grant liens on our assets, (ii) make certain fundamental changes, including merging or consolidating with another entity or making any material change in the nature of our business, (iii) make certain dividends or distributions, (iv) make certain loans or investments, (v) guarantee or become liable in any way on certain liabilities or obligations of any other person or entity, or (vi) incur certain indebtedness. Our prior credit agreement (as discussed below) included similar restrictions.
	The credit agreement contains certain covenants regarding our financial performance, including (i) a minimum tangible net worth of at least $20 million, (ii) a maximum funded debt to EBITDA of no more than 3.00 to 1.00, and (iii) a minimum quarterly net income of at least $250,000.
	The credit agreement replaced the credit facility we had in place with Wells Fargo, which was terminated upon the effectiveness of the credit agreement. We did not incur any early termination fees or penalties in connection with the termination of the prior credit agreement. Wells Fargo serves and may continue to serve as our transfer agent and has performed and may continue to perform commercial banking and financial services for us for which they have received and may continue to receive customary fees. The prior credit agreement provided for a revolving line of credit for a total maximum borrowing amount of $20.0 million.
	We had outstanding advances of $6.0 million on the prior credit agreement at December 31, 2012. At December 31, 2013, we had no outstanding advances on the prior credit agreement or the revolving facility. Of the $40 million maximum borrowing amount available under the combined floor plan line of credit and revolving facility, we had outstanding advances of $20.0 million on the floor plan line of credit related to the purchase of inventory from a vendor.

	On August 8, 2013, we entered into an underwriting agreement relating to the public offering of 3,300,000 shares of our common stock at a price to the public of $11.00 per share, less underwriting discounts. In addition, we granted the underwriters a 30-day option to purchase up to an additional 495,000 shares at $11.00 per share to cover over-allotments, if any. On August 14, 2013, we completed the offering of 3,795,000 shares of common stock at a price to the public of $11.00 per share.

	Stock Compensation Plans:
	In May 2011, our shareholders approved our 2011 Incentive Compensation Plan ("2011 Plan"). The 2011 plan replaced our existing 2009 Incentive Compensation Plan ("2009 Plan") and 2000 Director Stock Option Plan (the "Director Plan"), each of which terminated upon approval of the 2011 Plan on May 12, 2011. We reserved up to 750,000 initial shares of our common stock for possible issuance under the 2011 Plan and 303,943 shares remaining available for future grants under the 2009 Plan. Awards under the 2011 Plan may consist of options (non-qualified and incentive stock options), stock appreciation rights, or SARs, restricted stock units, performance units, dividend equivalents, annual incentive awards and other share-based awards as determined by our Compensation Committee. The terms and conditions of each award are set in an award agreement as determined by the Compensation Committee. As of December 31, 2013, there were 613,174 shares available for grant under the 2011 Plan.
	Time-based Restricted Stock Grants under our 2011 Plan:
	Under the 2011 Plan, eligible employees may be awarded shares of restricted stock. These shares generally vest three to four years after issuance, subject to continuous employment and certain other conditions. In 2013, 2012 and 2011, we issued 273,500, 279,428 and 140,000 shares, respectively, of time-based restricted stock to our executive management and certain other employees. Restricted shares are valued at the closing price of our stock on the date of grant and are expensed over the vesting period. Unrecognized compensation expense related to the non-vested stock grants was $3.4 million at December 31, 2013 and is expected to be recognized through October 2017. Compensation expense related to these restricted stock grants was $1.9 million in 2013, $910,000 in 2012 and $621,000 in 2011.
	In 2013, 2012 and 2011, we issued 36,000, 36,000 and 36,607 shares of common stock to members of the Board of Directors, respectively. Our non-employee directors receive 6,000 shares of restricted stock for their Board service. We issue the annual restricted stock grants on June 30 of each year and they vest one-quarter upon issuance and one-quarter on the following September 30, December 31, and March 31, respectively, provided that the director is still a member of the Board on that date. As of December 31, 2013, 9,000 shares of the 2013 restricted stock grant were not vested. The 2012 and 2011 awards to our directors have all vested. For 2013, 2012 and 2011, total compensation expense for these awards was approximately $424,000 $323,000 and $260,000, respectively.
	Performance-based Restricted Stock Grants under our 2011 Plan, 2009 Plan and Director Plan:
	Under the 2011 Plan, we are able to grant performance-based awards of restricted stock to our employees. The purpose of the performance-based grants is to retain key employees and to align key management with shareholders' interests.
	On December 23, 2013, we awarded 171,408 shares of restricted stock pursuant to our 2011 Plan to executive management. These shares vest as follows: two-thirds if we achieve 150% of the non-GAAP operating income target of $32.3 million for 2014, with such percentages adjusted according to the matrix approved by our compensation committee during the December 23, 2013 meeting (one-third of this subtotal will vest upon announcement of the non-GAAP operating income target, one-third will vest on the first anniversary of the announcement, and the last third of this subtotal will vest on the second anniversary of the announcement); one-third time-based vesting (one-third of this subtotal on the first anniversary of the grant date, one-third of this subtotal on the second anniversary of the grant date, and the last third of this subtotal on the third anniversary of the grant date), provided that the individual remains employed by us on these vesting dates. The total fair value of the shares that have not vested under this award is $1.9 million, comprised of $633,000 for the time-based awards and $1.3 million for the performance-based awards. We are amortizing the $633,000 fair value of the time-based shares that have not vested as follows: (1) $211,000 through the first anniversary of the grant date (2) $211,000 over the two-year vesting period and (3) $211,000 over the three-year vesting period.

The corresponding fair value of the performance-based shares executive management will receive if the Company achieves 100% of non-GAAP operating income during 2014 is $633,000 and will vest as follows: (1) $211,000 over the 14-month period for the achievement of the performance objectives and remaining employed by us through the announcement of 2014 financial results, (2) $211,000 over the two-year vesting period (3) $211,000 over the three-year vesting period.

We use the Black-Scholes option pricing model to estimate the fair value of stock options. The weighted-average fair value per option at the date of grant was $2.15.
	Total stock-based compensation expense related to stock options was $134,000 and $242,000 and $264,000 for the years ended December 31, 2013, 2012 and 2011, respectively. At December 31, 2013 there were no unrecognized stock-based compensation expense related to stock options.

	We occasionally enter into sales-type lease agreements with our customers resulting from the sale of certain products. Our lease receivables are recorded at cost within the accounts receivable and long-term lease receivables balances on our balance sheet and are due in installments over the lives of the leases. Cash received and applied against this receivable balance is recorded within changes in operating assets and liabilities in the net cash provided by operating activities section of the statement of cash flows. Finance income is derived over the term of the sales-type lease arrangement as the unearned income on financed sales-type leases is earned. Unearned income is amortized over the life of the lease using the interest method. The present value of net investment in sales-type lease receivables of $1.3 million and $1.0 million at December 31, 2013 and 2012, respectively, is reflected net of unearned income of $57,000 and $60,000 at December 31, 2013 and 2012, respectively. As of December 31, 2013, scheduled maturities of minimum lease payments receivable were as follows for the fiscal years ended December 31:

Summary of Significant Accounting Policies:	'
Recently Issued and Adopted Accounting Standard:	'
	Recently Issued and Adopted Accounting Standard:
	In July 2013, the FASB issued Accounting Standards Update No. 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists ("ASU No. 2013-11"). ASU No. 2013-11 provides guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. ASU No. 2013-11 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of ASU No. 2013-11 will not have a significant impact on our consolidated financial statements.
	In July 2012, the FASB issued an update to ASC 350: Testing Indefinite-Lived Intangible Assets for Impairment. This update states that an entity has the option first to assess qualitative factors to determine whether the existence of events and circumstances indicates that it is more likely than not that the indefinite-lived intangible asset is impaired. If, after assessing the totality of events and circumstances, an entity concludes that it is not more likely than not that the indefinite-lived intangible asset is impaired, then the entity is not required to take further action. However, if an entity concludes otherwise, then it is required to determine the fair value of the indefinite-lived intangible asset and perform the quantitative impairment test by comparing the fair value with the carrying amount in accordance with ASC 350. Under the guidance in this update, an entity also has the option to bypass the qualitative assessment for any indefinite-lived intangible asset in any period and proceed directly to performing the quantitative impairment test. An entity will be able to resume performing the qualitative assessment in any subsequent period. The amendments to ASC 350 are effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. The adoption of this update did not have a material impact on our financial statements.
Cash and Cash Equivalents:	'
	Cash and Cash Equivalents:
	Cash equivalents consist principally of money market funds with original maturities of three months or less, are readily convertible to cash and are stated at cost, which approximates fair value. We maintain our cash in bank deposit and money market accounts which, at times, may exceed federally insured limits. We have not experienced any losses in such accounts.
Short-Term Investments:	'
	Short-Term Investments:
	Our short term investments consist principally of commercial paper and corporate bonds. We categorize these investments as trading securities and record them at fair value. We classify investments with maturities of 90 days or less from the date of purchase as cash equivalents; investments with maturities of greater than 90 days from the date of purchase but less than one year generally as short-term investments; and investments with maturities of greater than one year from the date of purchase generally as long-term investments.
Accounts Receivable, net:	'
	Accounts Receivable, net:
	We carry accounts receivable at original invoice amount less an estimate made for doubtful receivables based on a review of all outstanding amounts on a monthly basis. Management determines the allowance for doubtful accounts by regularly evaluating individual customer receivables and considering a customer's financial condition and credit history and current economic conditions. We write off accounts receivable when deemed uncollectible, which is generally in excess of a year past due provided we have no additional information to suggest we continue to expect customer payment. We record recoveries of accounts receivable previously written off when received.
	We recorded accounts receivable net of the reserve for doubtful accounts of $331,000 and $223,000 at December 31, 2013 and 2012, respectively.
Concentration of Credit Risk:	'
	Concentration of Credit Risk:
	We had no customers that comprised more than 10% of our net sales in 2013, 2012 or 2011. However, our top five customers collectively accounted for 10%, 11%, and 11% of our 2013, 2012, and 2011 revenues, respectively.
Inventories:	'
	Inventories:
	Inventories, including inventories shipped but not installed, principally consist of data storage products and components, valued at the lower of cost or market with cost determined on a first-in, first-out (FIFO) method. We reduced inventories for obsolete and slow moving reserves by $89,000 and $310,000 at December 31, 2013 and 2012, respectively.
Property and Equipment:	'
	Property and Equipment:
	We state property and equipment, including purchased software, at cost. We provide for depreciation and amortization by charges to operations using the straight-line method over the estimated useful lives of the assets (ranging from 2 to 10 years). We amortize leasehold improvements on a straight-line basis over the shorter of their estimated useful lives or the underlying lease term. We remove the costs and related accumulated depreciation and amortization on asset disposals from the accounts and include any gain or loss in operating expenses. We capitalize major renewals and betterments, but charge maintenance and repairs to current operations when incurred.

Goodwill:	'
	Goodwill:
	We assess the carrying amount of our goodwill for potential impairment annually or more frequently if events or a change in circumstances indicate that impairment may have occurred. We have only one operating and reporting unit that earns revenues, incurs expenses and makes available discrete financial information for review by our chief operations decision maker. Accordingly, we complete our goodwill impairment testing on this single reporting unit. Our measurement date is December 31st of each year.
	Testing for goodwill impairment is a two step process. The first step screens for potential impairment. If there is an indication of possible impairment, we must complete the second step to measure the amount of impairment loss, if any. The first step of the goodwill impairment test, used to identify potential impairment, compares the fair value of our market capitalization with the carrying value of our net assets. If our total market capitalization is at or below the carrying value of our net assets, we perform the second step of the goodwill impairment test to measure the amount of impairment loss we record, if any. We consider goodwill impairment test estimates critical due to the amount of goodwill recorded on our balance sheet and the judgment required in determining fair value amounts. At each of December 31, 2013 and 2012, we determined that our goodwill was not impaired.
Valuation of Long-Lived Assets:	'
	Valuation of Long-Lived Assets:
	We perform an impairment test for finite-lived assets and other long-lived assets, such as property and equipment and finite-lived intangible assets, whenever events or changes in circumstances indicate that we may not recover the carrying value of such assets. We recognize impairment based on the difference between the fair value of the asset and its carrying value. We generally measure fair value based on discounted cash flow analyses. For 2013 and 2012, we identified no triggering events that required us to evaluate the impairment of our long-lived assets.
Stock Compensation Plans:	'
	Stock Compensation Plans:
	We utilize the fair value method of accounting to account for share-based compensation awards. This requires us to measure and recognize in our statements of operations the expense associated with all share-based payment awards made to employees and directors based on estimated fair values. We use the Black-Scholes model to determine the fair value of share-based payment awards. Stock-based compensation expense was $4.0 million, $2.6 million and $2.6 million for 2013, 2012 and 2011, respectively.
Income Taxes:	'
	Income Taxes:
	We calculate income taxes using the asset and liability method of accounting for income taxes. Under the liability method, we record deferred income taxes to reflect the tax consequences in future years of temporary differences between the tax bases of assets and liabilities and their financial reporting amounts using enacted tax rates for the years in which we expect these items to affect taxable income. We establish valuation allowances when necessary to reduce deferred tax assets to the amount we expect more likely than not to realize. Income tax expense is the tax payable for the period and the change during the period in deferred tax assets and liabilities.
Uncertain Tax Positions:	'
	Uncertain Tax Positions:
	We utilize a two-step approach to recognizing and measuring uncertain tax positions (tax contingencies). The first step evaluates the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not that we will sustain the position on audit, including resolution of related appeals or litigation processes. The second step measures the tax benefit as the largest amount more than 50% likely of being realized upon ultimate settlement. We include interest and penalties for our tax contingencies in income tax expense. At December 31, 2013 and 2012, we had no unrecognized tax benefits which would affect our effective tax rate if recognized.
Use of Estimates:	'
	Use of Estimates:
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires our management 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. Significant items subject to estimates and assumptions include the reserve for doubtful accounts, reserve for obsolete and slow moving (excess) inventory and impairment analysis of goodwill and long-lived assets. Actual results could differ from those estimates.
Advertising Costs:	'
	Advertising Costs:
	Advertising and promotion costs are charged to operations as incurred. Advertising and promotion costs included in sales and marketing expense for 2013, 2012 and 2011 were $683,000, $559,000 and $728,000, respectively.
Revenue Recognition:	'
	Revenue Recognition:
	Product Sales.    We sell software and hardware products on both a "free-standing" basis without any services and as data center solutions bundled with installation and configuration services ("bundled arrangements"). Under either arrangement, we recognize revenue from the sales of products, primarily hardware and essential software, when persuasive evidence of an arrangement exists, shipment has occurred and title has transferred, the sales price is fixed or determinable, and collection of the resulting receivable is reasonably assured. In customer arrangements where a formal acceptance of products is required by the customer, revenue is recognized upon meeting such acceptance criteria.
	Service Sales.    In addition to installation and configuration services provided by us or third party vendors as part of our bundled arrangements, our service sales include postcontract customer support ("PCS") and consulting services. On our balance sheet, deferred revenue relates to service sales for which our customer has paid us or has been invoiced but for which we have not yet performed the applicable services. Revenue from extended service contracts is recognized ratably over the contract term, generally one to three years. Professional services are offered under time and material or fixed fee-based contracts or as part of multiple-element arrangements. Professional services revenue is recognized as services are performed when sold on a stand-alone basis. Our service sales include customer support contracts and consulting services.
	Postcontract Customer Support Contracts.    When we sell hardware and/or software products to our customers, we enter into service contracts with them. These contracts are support service agreements. A majority of the time, our internal support desk first assists the customer by performing an initial technical triage to determine the source of the problem and whether we can direct the customer on how to fix the problem. If we cannot solve the problem, we transfer the customer to the manufacturer or its designated service organization.
	When we do not provide "first call" assistance, usually because the manufacturer has not authorized us to do so, our customers call the manufacturer or its designated service organization directly for both the initial technical triage and any follow-up assistance. If the customer calls us first, we transfer the customer to the third party.
	In both scenarios above, we purchase third party support contracts from the manufacturers for their services. In accordance with our agreements, and consistent with standard industry practice, we prepay the third party based on its "list price" for maintenance on the specific hardware or software products we have sold, less our negotiated discounts with the third party. Terms are generally net 30 days. If we provide the initial "first call" services our discounts off of list price are more substantial. In all cases, we are the primary obligor in the transaction. The customer ultimately holds us responsible for fulfillment of the third party support contracts and we bear credit risk in the event of nonpayment by the customer.
	We report customer support contract revenue on a gross basis as there are sufficient indicators in accumulation that we should be reporting these revenues on a gross basis in accordance with ASC Topic 605-45, Reporting Revenue Gross as a Principle versus Net as an Agent. We usually present quotations for maintenance arrangements to our customers without differentiating as to whether we, or a third party, are providing the service. Accordingly, we are, from our customers' perspectives, the primary obligor on our maintenance arrangements. We directly enter into the agreements with our customers to provide maintenance services. In all cases, we set the price to our customer for the maintenance arrangements, whether or not we provide our first call services, and bill our customers for the maintenance arrangement. We owe various third parties regardless of whether we collect from our customer. We are also contractually obligated to provide or arrange to provide these underlying support services to our customers in the unlikely event that the manufacturer or its designated service organization, fails to perform according to the terms of our contract.
	When we sell a service contract as part of a bundled arrangement, we use vendor specific objective evidence ("VSOE") to allocate revenue to the service contract element. In all cases, we defer revenues and incremental direct costs resulting from obtaining our service contracts and amortize them into operations over the term of the contracts, which are generally twelve months. We defer customer support costs as allowed under ASC Topic 605-10-S99 based on the guidance in ASC Topic 605-20. The deferred costs we capitalize consist of direct and incremental costs we prepay to third parties for direct support to our customers under our contract terms. We defer our customer support contract revenues and their related costs because significant obligations remain after contract execution. For example, we provide routine help desk assistance to our customers and assist them in contacting our vendors for additional support services.
	Consulting Services.    Some of our customers engage us to analyze their existing data center architectures and offer our recommendations. Other customers engage us to assist them on-site with extended data center infrastructure projects, to support their data center environments and to help with long-term data center design challenges. For these types of consulting services that do not include the sale of hardware or software products, we recognize revenues as we perform these services.
	Multiple Element Arrangements. In October 2009, the FASB amended the Accounting Standards Codification ("ASC") as summarized in Accounting Standards Update ("ASU") No. 2009-14, Software (Topic 985): Certain Revenue Arrangements That Include Software Elements, and ASU No. 2009-13, Revenue Recognition (Topic 605): Multiple-Deliverable Revenue Arrangements. ASU 2009-14 amended industry specific revenue accounting guidance for software and software related transactions to exclude from its scope tangible products containing software components and non-software components that function together to deliver the product's essential functionality, or what we refer to as essential software. We also sell non-essential software, which continues to be in the scope of ASC 985-605. ASU 2009-13 amended the accounting for multiple-element arrangements to provide guidance on how the deliverables in an arrangement should be separated and eliminates the use of the residual method. ASU 2009-13 also required an entity to allocate revenue using the relative selling price method.
	ASU 2009-13 establishes a hierarchy of evidence to determine the stand-alone selling price of a deliverable based on VSOE, third-party evidence ("TPE"), and the best estimate of selling price ("BESP"). If VSOE is available, it would be used to determine the selling price of a deliverable. If VSOE is not available, the entity would determine whether TPE is available. If so, TPE must be used to determine the selling price. If TPE is not available, then the BESP would be used.
	In certain instances, we are not able to establish VSOE for all deliverables in an arrangement with multiple elements. This may be due to infrequent sales of each element separately, not pricing products within a narrow range, or only having a limited sales history. We have not consistently established VSOE for any of our products or services, except for PCS.
	When VSOE cannot be established, we attempt to determine the standalone selling price for each element based on TPE. TPE is determined based on competitor prices for similar deliverables when sold separately. Generally, our strategy differs from that of our peers and our offerings contain a significant level of customization and differentiation such that the comparable pricing of products with similar functionality cannot be obtained. Furthermore, we are unable to reliably determine what similar competitor products' selling prices are on a stand-alone basis. Therefore, we are typically not able to determine TPE.
	Since we are typically unable to determine VSOE or TPE, we use BESP in our allocation of the arrangement consideration where VSOE or TPE do not exist. Therefore, revenue from these multiple-element arrangements is allocated based on BESP, except for PCS which is allocated based on VSOE. The objective of BESP is to determine the price at which we would transact a sale if the product or service were sold on a stand-alone basis. BESP is generally used for offerings that are not typically sold on a stand-alone basis or for new or highly customized offerings. We determine BESP for product or service using a cost-plus margin approach. When establishing the methodology used to calculate BESP we also considered multiple factors, including, but not limited to, geographies, market conditions, competitive landscape, internal costs, gross margin objectives and pricing practices. The determination of BESP is made through consultation with and formal approval by management.
	We regularly review VSOE, TPE and BESP and maintain internal controls over the establishment and updates of these estimates. We limit the amount of revenue recognized for delivered elements to the amount that is not contingent on the future delivery of products or services, future performance obligations or subject to customer-specified return or refund privileges.
	We evaluate each deliverable in an arrangement to determine whether they represent a single unit of accounting. The delivered item constitutes a separate unit of accounting when it has stand-alone value and there are no customer-negotiated refunds or return rights for the delivered elements. If the arrangement includes a customer-negotiated refund or return right relative to the delivered item and the delivery and performance of the undelivered item is considered probable and substantially in our control, the delivered element would also constitute a separate unit of accounting. In instances when the aforementioned criteria are not met, the deliverable is combined with the undelivered elements and revenue recognition is determined for the combined unit as a single unit of accounting. Allocation of the consideration is determined at arrangement inception on the basis of each unit's relative selling price.
	Our multiple-element product offerings include networking hardware with embedded software products, professional services, and PCS, which are considered separate units of accounting. For fiscal year 2011 and future periods, pursuant to the guidance in ASU 2009-13, when a sales arrangement contains multiple elements, such as products, essential software, PCS and/or professional services, we will allocate revenues to each element based on the aforementioned selling price hierarchy.
	In multiple-element arrangements that include software that is not essential to the functionality of the products, revenue is initially allocated to each separate unit of accounting using the relative selling prices of each of the deliverables in the arrangement based on the aforementioned selling price hierarchy. Since non-essential software deliverables are in the scope of ASC 985-605, VSOE must exist to account for the non-essential software deliverables as separate units of accounting from one another and further allocate the originally allocated non-essential software fee among the individual non-essential software deliverables. Since we were only able to establish VSOE for PCS, the amount allocated to the other non-essential software deliverables would be based on the residual method of allocation using VSOE for PCS. This allocated revenue is recognized once all non-essential software deliverables other than PCS are delivered.
	In 2013, we began recognizing revenue on certain new professional service contracts that include milestones using a proportional performance method of revenue recognition. Revenues from these fixed price professional service contracts are recognized as services are performed based on the achievement of specified milestones within the contracts and when the customer acknowledges that such criteria have been satisfied. We invoice our customer on these projects as agreed-upon project milestones are achieved and accepted by the customer. We recognized approximately $1.2 million of services revenues under this method during 2013.
Net Earnings Per Share:	'
	Net Earnings Per Share:
	We compute basic net earnings per share using the weighted average number of shares outstanding. Diluted net earnings per share include the effect of common stock equivalents, if any, for each period. Diluted per share amounts assume the conversion, exercise or issuance of all potential common stock instruments unless their effect is anti-dilutive. The following table computes basic and diluted net earnings per share:

Fair Value of Financial Instruments:	'
	Fair Value of Financial Instruments:
	Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In determining fair value for assets and liabilities required or permitted to be recorded at fair value, we consider the principal or most advantageous market in which it would transact and the assumptions that market participants would use when pricing the asset or liability. We apply fair value measurements for both financial and nonfinancial assets and liabilities. We have no nonfinancial assets or liabilities that require measurement at fair value on a recurring basis as of December 31, 2013.
	The fair value of our financial instruments, including cash and cash equivalents, short-term investments, accounts receivable, accounts payable, line of credit and accrued expenses, approximate cost because of their short maturities.
	We use the three-level fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair values. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below:
	•
	Level 1—Unadjusted quoted prices available in active markets for the identical assets or liabilities at the measurement date.
	•
	Level 2—Significant other observable inputs available at the measurement date, other than quoted prices included in Level 1, either directly or indirectly.
	•
	Level 3—Significant unobservable inputs that we cannot corroborate by observable market data and thus reflect the use of significant management judgment. We generally determine these values using pricing models based on assumptions our management believes other market participants would make.
	The fair value hierarchy requires the use of observable market data when available. In instances in which the inputs used to measure fair value fall into different levels of the fair value hierarchy, we determine the fair value measurement based on the lowest level input that is significant to the fair value measurement in its entirety. Our assessment of the significance of a particular item to the fair value measurement in its entirety requires judgment, including the consideration of inputs specific to the asset or liability. The following table sets forth, by level within the fair value hierarchy, the accounting of our financial assets and/or liabilities at fair value on a recurring basis according to the valuation techniques we used to determine their fair value(s):
