PFSweb Overview PFSweb is a global provider of omni-channel commerce solutions, including a broad range of technology, infrastructure and professional services, to major brand name companies and others seeking to optimize their supply chain and to enhance their online and traditional business channels and initiatives in the United States, Canada, and Europe. PFSweb’s service offerings include website design, creation and integration, digital agency and marketing, eCommerce technologies, order management, customer care, logistics and fulfillment, financial management and professional consulting. Supplies Distributors Overview Supplies Distributors and PFSweb operate under distributor agreements with Ricoh Company Limited and Ricoh USA Inc., a strategic business unit within the Ricoh Family Group of Companies (collectively hereafter referred to as “Ricoh”), under which Supplies Distributors acts as a distributor of various Ricoh products. Supplies Distributors sells its products in the United States, Canada and Europe. Pursuant to agreements between PFSweb and Supplies Distributors, PFSweb provides transaction management and fulfillment services to Supplies Distributors. The majority of Supplies Distributors’ revenue is generated by its sale of product purchased from Ricoh. Under the distributor agreements, which are subject to periodic renewals, Ricoh sells product to Supplies Distributors and reimburses Supplies Distributors for certain freight costs, direct costs incurred in passing on any price decreases offered by Ricoh to Supplies Distributors or its customers to cover price protection and certain special bids, the cost of products provided to replace defective product returned by customers and other certain expenses, as defined. Supplies Distributors can return to Ricoh product rendered obsolete by Ricoh engineering changes after customer demand ends. Ricoh determines when a product is obsolete. Ricoh and Supplies Distributors also have agreements under which Ricoh reimburses or collects from Supplies Distributors amounts calculated in certain inventory cost adjustments. Supplies Distributors passes through to customers marketing programs specified by Ricoh and administers such programs according to Ricoh guidelines. Supplies Distributors also maintains agreements with certain additional clients where it operates as an agent for the resale of product between the client and the customer, and records product revenue net of cost of product revenue as a component of service fee revenue.

Significant Accounting Policies	Dec. 31, 2017
Accounting Policies [Abstract]
Significant Accounting Policies	2. Significant Accounting Policies Principles of Consolidation All intercompany accounts and transactions have been eliminated in consolidation. Use of Estimates The preparation of consolidated financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America (“US GAAP”) requires management to make judgments, estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and disclosure of contingent assets and liabilities. The recognition and allocation of certain revenues and selling, general and administrative expenses in these consolidated financial statements also require management estimates and assumptions. Estimates and assumptions about future events and their effects cannot be determined with certainty. The Company bases its estimates on historical experience and various other assumptions believed to be applicable and reasonable under the circumstances. These estimates may change as new events occur, as additional information is obtained and as the operating environment changes. These changes have been included in the consolidated financial statements as soon as they became known. In addition, management is periodically faced with uncertainties, the outcomes of which are not within its control and will not be known for prolonged periods of time. Based on a critical assessment of accounting policies and the underlying judgments and uncertainties affecting the application of those policies, management believes the Company’s consolidated financial statements are fairly stated in accordance with US GAAP, and provide a fair presentation of the Company’s financial position and results of operations. Revenue and Cost Recognition The Company derives revenue primarily from services provided under contractual arrangements with its clients or from the sale of products under its distributor agreements. The following revenue recognition policies define the manner in which the Company accounts for sales transactions. The Company recognizes revenue when persuasive evidence of a sales arrangement exists, product shipment or delivery has occurred or services have been rendered, the sales price or fee is fixed or determinable, and collectability is reasonably assured. In instances where revenue is derived from sales of third-party vendor products or services, the Company records revenue on a gross basis when the Company is a principal to the transaction and net of costs when the Company is acting as an agent between the customer or client and the vendor. The Company considers several factors to determine whether it is a principal or an agent, most notably whether the Company is the primary obligor to the vendor or customer, has established its own pricing and has inventory and credit risks, if applicable. Service Fee Revenue Activity The Company’s service fee revenue primarily relates to its distribution services, order management/customer care services, professional digital agency and technology services. The Company typically charges its service fee revenue on either a cost-plus basis, a percent of shipped revenue basis, on a time and materials, project or retainer basis for professional services, or a per transaction basis, such as a per item basis for fulfillment services or a per labor hour basis for web-enabled customer contact center services. Additional fees are billed for other services. The Company evaluates its contractual arrangements to determine whether or not they include multiple service elements. Revenue recognition is determined for the separate service elements of the contract in accordance with the requirements of Accounting Standards Codification (“ASC”) 605, “Revenue Recognition.” A deliverable constitutes a separate unit of accounting when it has standalone value and there are no return rights or other contingencies present for the delivered elements. The Company allocates revenue to each element based on estimated selling price. Each of the Company’s client contracts, and the related services, is unique, with individual needs and criteria customized for each client. Each client engagement is scoped and priced separately and as such the Company is not able to establish vendor specific objective evidence of fair value for its services, nor is third-party evidence available to establish stand-alone selling prices. Accordingly, the Company uses management’s best estimate of selling price for the deliverables. The Company establishes its estimates considering internal factors, such as margin objectives, pricing practices and controls, as well as market conditions, such as competitor pricing strategies. Distribution services relate primarily to inventory management, product receiving, warehousing and fulfillment (i.e., picking, packing and shipping) and facilities and operations management. Service fee revenue for these activities is recognized as earned, which is either (i) on a per transaction basis or (ii) at the time of product fulfillment, which occurs at the completion of the distribution services. Order management/customer care services relate primarily to taking customer orders for the Company’s clients’ products. These services also include addressing customer questions related to orders, as well as cross-selling/up-selling activities. Service fee revenue for this activity is recognized as the services are rendered. Fees charged to the client are on a per transaction basis based on either (i) a pre-determined fee per order or fee per telephone minutes incurred, (ii) a per dedicated agent fee, or (iii) are included in the product fulfillment service fees that are recognized on product shipment. Professional consulting and technology service revenues primarily relate to design, implementation, service and support of eCommerce platforms, website design and solutions and quality control for the Company’s clients. Additionally, the Company provides digital agency services that enable client marketing programs to attract new customers, convert buyers and increase website value. These fees are typically charged on either a per labor hour or transaction basis, a dedicated resource model, a fixed price arrangement, or a percent of merchandise shipped basis. Service fee revenue for this activity is generally recognized as the services are rendered. The Company performs front-end set-up and integration services to support client eCommerce platforms and websites. When the Company determines these front-end set-up and integration services do not meet the criteria for recognition as a separate unit of accounting, the Company defers the start-up fees received and the related costs, and recognizes them over the expected performance period. When the Company determines these front-end set-up and integration services do meet the criteria for recognition as a separate unit of accounting, for time and material arrangements, the Company recognizes revenue as services are rendered and costs as they are incurred. For fixed-price arrangements, the Company uses the completed contract method to recognize revenues and costs if reasonable and reliable cost estimates for a project cannot be made. If reasonable and reliable costs estimates for a project can be made, the Company recognizes revenue over the expected performance period on a proportional performance basis, as determined by the relationship of actual costs incurred compared to the estimated total contract costs. The Company’s billings for reimbursement of out-of-pocket expenses, including travel and certain third-party vendor expenses, such as shipping and handling costs and telecommunication charges, are included in pass-through revenue. The related reimbursable costs are reflected as cost of pass-through revenue. The Company’s cost of service fee revenue, representing the cost to provide the services described above, is recognized as incurred. Cost of service fee revenue also includes certain costs associated with technology collaboration and ongoing technology support that include maintenance, web hosting and other ongoing programming activities. These activities are primarily performed to support the distribution and order management/customer care services and are recognized as incurred. Product Revenue Activity Depending on the terms of the customer arrangement, Supplies Distributors recognizes product revenue and product cost either upon the shipment of product to customers or when the customer receives the product. Supplies Distributors permits its customers to return product for credit against other purchases, which include returns for defective products (that Supplies Distributors then returns to the manufacturer) and incorrect shipments. Supplies Distributors provides a reserve for estimated returns and allowances and offers terms to its customers that it believes are standard for its industry. Freight costs billed to customers are reflected as components of product revenue. Freight costs incurred are recorded as a component of cost of product revenue. Under its distributor agreements, Supplies Distributors bills Ricoh for reimbursements of certain expenses, including: pass-through customer marketing programs, including rebates and coop funds; certain freight costs; direct costs incurred in passing on any price decreases offered by Ricoh to Supplies Distributors or its customers to cover price protection and certain special bids; the cost of products provided to replace defective product returned by customers; and certain other expenses as defined. Supplies Distributors records these reimbursable amounts as they are incurred as other receivables in the consolidated balance sheet with a corresponding reduction in either inventory or cost of product revenue. Supplies Distributors also records pass-through customer marketing programs as a reduction of both product revenue and cost of product revenue. Deferred Revenues and Deferred Costs The Company primarily performs its distribution services, order management, customer care and certain other services under multiple year contracts, certain of which include early termination provisions, and clients are obligated to pay for services performed. In conjunction with these long-term contracts, the Company sometimes receives start-up fees to cover its implementation costs, including certain technology infrastructure and development costs. When the Company determines that these start-up and integration activities do not meet the criteria for recognition as a separate unit of accounting, the Company defers the start-up fees received, and the related costs, and recognizes them over the expected performance period. The amortization of deferred revenue is included as a component of service fee revenue. The amortization of deferred implementation costs is included as a cost of service fee revenue. To the extent implementation costs for non-technology infrastructure and development exceed the corresponding fees received, the excess costs are expensed as incurred. Current and non-current deferred implementation costs, excluding technology and development costs, are a component of prepaid expenses and other current assets and other assets, respectively. Concentration of Business and Credit Risk During 2017 and 2016, no product customer or service fee client relationships represented more than 10% of the Company’s consolidated total net revenues. During 2015, one service fee client relationship, the United States Mint, represented approximately 11%, or $31.2 million, of the Company’s consolidated total net revenues. As of December 31, 2017, no client exceeded 10% of the Company’s total accounts receivable. As of December 31, 2016, one client exceeded 10% of the Company’s consolidated accounts receivable. Cash and Cash Equivalents Cash equivalents are defined as short-term highly liquid investments with original maturities, when acquired, of three months or less. At times, the Company has cash balances in domestic bank accounts that exceed Federal Deposit Insurance Corporation insured limits. The Company has not experienced any losses related to these cash concentrations. Accounts Receivable The Company recognizes revenue and records trade accounts receivable, pursuant to the methods described above, when collectability is reasonably assured. Collectability is evaluated in the aggregate and on an individual customer or client basis taking into consideration payment due date, historical payment trends, current financial position, results of independent credit evaluations and payment terms. Related reserves are determined by either using percentages applied to certain aged receivable categories based on historical results, reevaluated and adjusted as additional information is received, or a specific identification method. After all attempts to collect a receivable have failed, the receivable is written off against the allowance for doubtful accounts. Other Receivables Other receivables primarily include amounts due from Ricoh for costs incurred by the Company under the distributor agreements and value added tax receivables. Inventories Inventories (all of which are finished goods) are stated at the lower of weighted average cost and net realizable value. The Company establishes inventory reserves based upon estimates of declines in values due to inventories that are slow moving or obsolete, excess levels of inventory or values assessed at lower than cost. Supplies Distributors assumes responsibility for slow-moving inventory under its Ricoh distributor agreements, subject to certain termination rights, but has the right to return product rendered obsolete by engineering changes, as defined. In the event PFSweb, Supplies Distributors and Ricoh terminate the distributor agreements, the agreements provide for the parties to mutually agree on a plan of disposition of Supplies Distributors’ then existing inventory. Property and Equipment The Company makes judgments and estimates in conjunction with the carrying value of property and equipment, including amounts to be capitalized, depreciation and amortization methods and useful lives. Property and equipment are stated at cost and are depreciated using the straight-line method over the estimated useful lives of the respective assets. Capitalized implementation costs are depreciated over the respective client expected performance period. Leasehold improvements are amortized over the shorter of the useful life of the related asset or the remaining lease term. When events or changes in circumstances indicate that the carrying amount of our property and equipment might not be recoverable, the expected future undiscounted cash flows from the asset are estimated and compared with the carrying amount of the asset. If the sum of the estimated undiscounted cash flows is less than the carrying amount of the asset, an impairment loss is recorded. The impairment loss is measured by comparing the fair value of the asset with its carrying amount. Fair value is generally determined based on discounted cash flows or appraised values, as appropriate. Business Combinations The Company accounts for business combinations under the acquisition method of accounting, which requires the assets and liabilities to be recorded at their respective fair values as of the acquisition date in the consolidated financial statements. The determination of estimated fair value may require management to make significant estimates and assumptions. The purchase price is the fair value of the total consideration conveyed to the seller and the excess of the purchase price over the fair value of the acquired identifiable net assets, where applicable, is recorded as goodwill. The results of operations of an acquired business are included in the Company’s consolidated financial statements from the date of acquisition. Costs associated with the acquisition of a business are expensed in the period incurred. Definite-Lived Intangible Assets The Company’s definite-lived intangible assets are primarily comprised of non-compete agreements, trade names, customer relationships and developed technology. Definite-lived intangible assets are amortized over their estimated useful life and only tested for impairment whenever events or circumstances indicate that the carrying amount of an asset may not be recoverable. An impairment loss would be recognized when the carrying amount of the asset exceeds the estimated undiscounted future cash flows expected to result from the use of the asset and its eventual disposition. The impairment loss to be recorded would be the excess of the asset’s carrying value over its fair value. Fair value is determined using a discounted cash flow analysis or other valuation technique. Goodwill Goodwill represents the excess of the purchase price over the fair value of the identifiable net assets acquired. Goodwill and other intangible assets with indefinite lives are not amortized to operations, but instead are reviewed for impairment at least annually in the fourth quarter, or more frequently when there is an indicator of impairment. Goodwill impairment exists when a reporting unit’s goodwill carrying value exceeds its implied fair value. The Company has no intangible asset with indefinite useful lives, other than goodwill. ASU Topic 350: Testing Goodwill for Impairment (“ASU Topic 350”) permits an entity to make a qualitative assessment of whether it is more likely than not that a reporting unit’s fair value is less than its carrying amount before applying a two-step goodwill impairment test. This qualified assessment is referred to as “Step 0.” When performing Step 0, an entity evaluates relevant events and circumstances, including but not limited to, macroeconomic conditions, industry and market conditions, overall financial performance, reporting unit specific events and entity specific events. If, after completing Step 0, an entity concludes that it is not likely that the fair value of the reporting unit is less than its carrying amount, it would not be required to perform a two-step impairment test for that reporting unit. In the event that the conclusion of Step 0 requires the two-step test, the first step compares the fair value of the reporting unit with its carrying value, including goodwill. If the fair value of the reporting unit is less than its carrying value, an indication of goodwill impairment exists for the reporting unit and the entity must perform step two of the impairment test. Under step two, an impairment loss is recognized for any excess of the carrying amount of the reporting unit’s goodwill over the implied fair value of that goodwill. The implied fair value of goodwill is determined by allocating the fair value of the reporting unit in a manner similar to a purchase price allocation and the residual fair value after this allocation is the implied fair value of the reporting unit goodwill. Fair value of the reporting unit is determined using a discounted cash flow analysis. If the fair value of the reporting unit exceeds its carrying value, step two does not need to be performed. An impairment loss is recognized to the extent that the carrying amount of goodwill exceeds its implied fair value. If the Company is required to perform the two-step test described in the preceding paragraph, it would determine fair value using generally accepted valuation techniques, including discounted cash flows and market multiple analyses. These types of analyses contain uncertainties because they require management to make assumptions and to apply judgment to estimate industry economic factors and the profitability of future business strategies. The Company’s valuation methodology for assessing impairment would require management to make judgments and assumptions based on historical experience and projections of future operating performance. If these assumptions differ materially from future results, the Company may record impairment charges in the future. Foreign Currency Translation and Transactions The functional currency of each of the Company’s foreign subsidiaries is local currency. Assets and liabilities are translated at exchange rates in effect at the end of the period, and income and expense items are translated at the average exchange rates on a monthly basis. Translation adjustments are accumulated and reported as a component of accumulated other comprehensive income in the consolidated statements of shareholders’ equity. The Company includes currency gains and losses on short-term intercompany advances in the determination of net income and loss. The Company reports gains and losses on intercompany foreign currency transactions that are of a long-term investment nature as a component of accumulated other comprehensive income in the consolidated statements of shareholders’ equity. Stock-Based Compensation The Company uses stock-based compensation, including stock options, deferred stock units and other stock-based awards to provide long-term performance incentives for its executives, key employees and non-employee directors. From the service inception date to the grant date, the Company recognizes compensation cost for all share-based payments based on the reporting date fair value of the award. After the grant date, compensation cost is measured based on the grant date fair value. Depending on the conditions associated with the vesting of the award, compensation cost is recognized on a straight-line or graded basis, net of estimated forfeitures, over the requisite service period of each award. The Company records compensation cost as a component of selling, general and administrative expenses in the consolidated statements of operations. The Company estimates the fair value of each option grant on the date of grant using the Black-Scholes option-pricing model and estimates the compensation cost for certain of the awards that have a performance condition using a Monte-Carlo simulation. The estimated fair value for awards involves assumptions for expected dividend yield, stock price volatility, risk-free interest rates and the expected life of the award. Income Taxes Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established when necessary to reduce deferred tax assets to the amount more likely than not to be realized. The Company recognizes interest and penalties related to certain tax positions in income tax expense and monitors uncertain tax positions and recognizes tax benefits only when management believes the relevant tax positions would more likely than not be sustained upon examination. Fair Value of Financial Instruments In accordance with ASC 825, Financial Instruments, fair value is determined utilizing a hierarchy of valuation techniques. The three levels of the fair value hierarchy are as follows: Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2: Inputs, other than quoted prices, that are observable for the asset or liability, either directly or indirectly; these include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. Level 3: Unobservable inputs that reflect the reporting entity’s own assumptions. The carrying value of the Company’s financial instruments, which include cash and cash equivalents, accounts receivable, accounts payable, debt and capital lease obligations, approximate their fair values at December 31, 2017 and 2016 based on short terms to maturity or current market prices and interest rates or observable inputs such as quoted prices in active markets. Nonrecurring Fair Value Measurements The purchase price of business acquisitions is allocated to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values on the acquisition dates, with any excess recorded as goodwill. The Company utilizes Level 3 inputs in the determination of the initial fair value of assets and liabilities. Non-financial assets such as goodwill, intangible assets, software development costs and property and equipment are subsequently measured at fair value when there is an indicator of impairment and recorded at fair value only when impairment is recognized. Impact of Recently Issued Accounting Standards Pronouncements Recently Adopted In July 2015, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standards Update (“ASU”) No. 2015-11, “Simplifying the Measurement of Inventory” (“ASU 2015-11”), which modifies existing requirements regarding measuring inventory at the lower of cost and market. Under existing standards, the market amount requires consideration of replacement cost, net realizable value (“NRV”), and NRV less an approximately normal profit margin. ASU 2015-11 replaces market with NRV, defined as estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. This eliminates the need to determine and consider replacement cost or NRV less an approximately normal profit margin when measuring inventory. This standard is effective for the Company prospectively beginning January 1, 2017. Adoption of ASU 2015-11 did not have a material impact on the Company’s consolidated financial statements. In November 2015, the FASB issued Accounting Standards Update No. 2015-17, “Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes” (“ASU 2015-17”), which simplifies the presentation of deferred income taxes by requiring deferred tax assets and liabilities be classified as noncurrent on the balance sheet. ASU 2015-17 is effective beginning on January 1, 2017 with early application permitted as of the beginning of any interim or annual reporting period. Adoption of ASU 2015-17 did not have a material impact on the Company’s consolidated financial statements. Pronouncements Not Yet Adopted In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, As Amended (“ASU 2014-09”), which will replace numerous requirements in U.S. GAAP, including industry-specific requirements, provides companies with a single revenue recognition model for recognizing revenue from contracts with customers and significantly expands the disclosure requirements for revenue arrangements. The new standard, as amended, will be effective for the Company for interim and annual reporting periods beginning on January 1, 2018. The two permitted transition methods under the new standard are the full retrospective method, in which case the standard would be applied to each prior reporting period presented, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized at the date of initial application with disclosure of results under the new and old standards for the first year of adoption. The Company will adopt the standard as of January 1, 2018, using the modified retrospective transition method. Under the modified retrospective transition method, the Company will calculate and record the cumulative effect of adopting the new standard at January 1, 2018 for all open contracts, in the Company’s Quarterly Report on Form 10-Q for the first quarter of 2018. Based on its evaluation process, the Company has identified certain potential areas of impact. Application of the new standard requires that incremental costs of obtaining a contract (including sales commissions plus any associated fringe benefits) be recognized as an asset and expensed over the expected life of the arrangement. Currently the Company expenses certain contract acquisition costs as incurred. Under the new standard the Company will defer incremental commission costs to obtain a contract and amortize those costs over the period of benefit. ASU 2014-09 allows, as a policy election, sales commissions related to contracts less than one year to be expensed as incurred instead of capitalized, as a practical expedient. The Company has elected this practical expedient. Therefore, only commissions related to contracts greater than one year will be capitalized. Additionally, the Company has reviewed the way it manages volume tiered discounts and penalties. Currently, revenue adjustments are recorded as discounts or penalties when incurred. Under ASU 2014-09, these items will be treated as variable consideration and good faith estimates will be made up front, which will have the impact of reducing some of the revenue. Variable consideration will be reassessed quarterly. Contract modifications under prior guidance were handled as modifications, if the adjustment was for additional hours on time and materials contracts, which were adjusted and charged as work is performed monthly. Under ASU 2014-09, we will continue to account for large scope changes with significant additional distinct services with related price increases that reflect our stand-alone selling price of the scope change as separate contracts. ASU 2014-09 allows, as a transition practical expedient, for contracts modified prior to the beginning of the earliest reporting period presented under the new standard (January 1, 2018 for the Company), an entity can reflect the aggregate effect of all modifications that occur before the beginning of the earliest period presented under the new standard when identifying the satisfied and unsatisfied performance obligations, determining the transaction price and allocating the transaction price to the satisfied and unsatisfied performance obligations for the modified contract at transition. We are electing this practical expedient. Based on contracts in process at December 31, 2017, the Company expects to record, upon adoption of ASU 2014-09, a net cumulative adjustment to shareholders’ equity not to exceed $1.0 million. The adjustment to retained earnings primarily relates to the modification of the amortization of implementation related deferred revenues and costs. Sales commissions were not a material amount for open contracts at December 31, 2017 and, therefore, will not have an impact at adoption. The Company will make certain presentation changes on its consolidated balance sheet to comply with the new standard. In February 2016, the FASB issued ASU No. 2016-02, “Leases” (“ASU 2016-02”). ASU 2016-02 establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company is currently assessing the impact of ASU 2016-02 on its consolidated financial statements, but does expect the adoption to have a material impact to the balance sheet through the addition of an ROU asset and corresponding lease liability. In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments - a consensus of the Emerging Issues Task Force” (“ASU 2016-15”). ASU 2016-15 is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. Certain issues addressed in this guidance include - debt payments or debt extinguishment costs, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, distributions received from equity method investments and beneficial interests in securitization transactions. ASU 2016-15 is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. ASU 2016-15 is not expected to have a material impact on the Company’s consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business” (“ASU 2017-01”). ASU 2017-01 clarifies the definition of a business when evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses, ASU 2017-01 is effective for annual reporting periods, and interim periods therein, beginning after December 15, 2017, and interim periods within those annual periods. ASU 2017-01 is not expected to have a material impact on the Company’s consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, “Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill impairment” (“ASU 2017-04”), which removes Step 2 of the goodwill impairment test. A goodwill impairment will now be determined by the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. ASU 2017-04 is effective for annual reporting periods, and interim periods therein, beginning after December 15, 2019, with early adoption permitted. The Company is currently evaluating the effect of ASU 2017-04. On May 10, 2017, the FASB issued ASU No. 2017-09, “Compensation–Stock Compensation (Topic 718): Scope of Modification Accounting” (“ASU 2017-09”), clarifying when a change to the terms or conditions of a stock-based payment award must be accounted for as a modification. ASU 2017-09 requires modification accounting if the fair value, vesting condition or the classification of the award is not the same immediately before and after a change to the terms and conditions of the award. ASU 2017-09 is effective for the Company on a prospective basis beginning on January 1, 2018. ASU 2017-09 is not expected to have an impact on the Company’s consolidated financial statements as it is not the Company’s practice to change either the terms or conditions of stock-based payment awards once they are granted.

Acquisitions

3. Acquisitions

Acquisition of Conexus

On June 8, 2016, PFSweb, Inc. acquired the outstanding capital stock of Conexus, an eCommerce system integrator that provides strategic consulting, system integration, and managed services for leading businesses and technology companies through its primary operations in Basingstoke, Hampshire, U.K. The purchase price for the shares consisted of (i) an initial cash payment of £5,855,000 (approximately $8.5 million as of the acquisition date), subject to a post-closing adjustment based upon a May 31, 2016 balance sheet analysis, and (ii) up to an aggregate maximum of £1,445,000 (approximately $1.8 million at December 31, 2016), subject to Conexus achieving certain operational and financial targets during the post-closing period ending December 31, 2016 (the “Earn-out Payment”), subject to possible offsets for indemnification and other claims arising under the purchase agreement. Conexus did not achieve the operational and financial targets so the Company did not make any payments or record any liability as of December 31, 2017 or December 31, 2016 applicable to the Earn-out Payment.

The transaction was accounted for using the purchase method of accounting for business combinations and, accordingly, the assets acquired and liabilities assumed, including an allocation of purchase price, and the results of operations of Conexus, including the amortization of acquired intangible assets, have been included in the Company's consolidated financial statements since the date of acquisition, which for 2016 included $3.3 million of service fee revenue and approximately $0.8 million of net loss.

The Company determined fair value using a combination of the discounted cash flow, market multiple and market capitalization valuation methods. The following table summarizes the fair value of the tangible and intangible assets acquired and liabilities assumed (in thousands):

Cash	$	156
Accounts receivable, net		1,451
Other receivables		887
Other assets		421
Identifiable intangibles		2,035
Total assets acquired		4,950
Total liabilities assumed		2,218
Net assets acquired		2,732
Goodwill		6,336
Total purchase price	$	9,068

Purchase price for Conexus is as follows (in thousands):

Aggregate cash payments

8,515

Performance-based contingent payments (based on

estimated fair value at acquisition date)

553

Total purchase price

9,068

The excess of the purchase price over the fair value of the net identifiable assets acquired and liabilities assumed was allocated to goodwill. Total goodwill of $6.3 million, none of which is deductible for tax purposes, is not being amortized but is subject to an annual impairment test using a fair-value-based approach.

Acquisition of CrossView

On August 5, 2015, PFSweb, Inc. acquired substantially all of the assets, and assumed substantially all of the liabilities, in each case, other than certain specified assets and liabilities, of CrossView, Inc. (“CrossView”) an ecommerce systems integrator and provider of a wide range of ecommerce services in the U.S. and Canada.

Consideration paid by the Company included an initial cash payment of $30.7 million and 553,223 unregistered shares of Company common stock (approximately $6.3 million in value as of the acquisition date). The initial cash payment was subject to adjustment based upon a post-closing balance sheet reconciliation. In addition, the purchase agreement provides for future earn-out payments (“CrossView Earn-out Payments”) payable in 2016, 2017 and 2018 based on the achievement of certain 2015, 2016 and 2017 financial targets. The CrossView Earn-out Payments have no guaranteed minimum and an aggregate maximum of $18.0 million and are subject to possible offsets for indemnification and other claims. During 2016, the Company paid an aggregate of $7.9 million in settlement of the 2015 CrossView Earn-out Payments, of which, $1.6 million was paid by the issuance of 122,066 restricted shares of Company stock. During 2017, the Company paid an aggregate of $2.4 million in settlement of the 2016 CrossView Earn-out Payments, of which $0.4 million was paid by the issuance of 48,173 restricted shares of Company stock. The Company will pay 15% of any 2017 CrossView Earn-out Payments in restricted shares of Company common stock, based on its current market value at the time of issuance. As of December 31, 2017 and 2016, the Company had recorded a liability of $4.0 million and $4.1 million, respectively, applicable to the estimated CrossView Earn-out Payments, which is included in performance-based contingent payments in the consolidated balance sheets. The estimated performance-based contingent payment liability decreased from $4.1 million as of December 31, 2016 as a result of the payment of the 2016 CrossView Earn-out Payments partially offset by an increase in the estimated 2017 CrossView Earn-out Payments resulting from updated CrossView financial projections for the 2017 earn-out period.

The transaction was accounted for using the purchase method of accounting for business combinations and, accordingly, the assets acquired and liabilities assumed, including an allocation of purchase price, and the results of operations of CrossView, including the amortization of acquired intangible assets, have been included in the Company's consolidated financial statements since the date of acquisition, which for 2015 included $13.8 million of service fee revenue and $0.6 million of net income.

The Company determined fair value using a combination of the discounted cash flow, market multiple and market capitalization valuation methods. The following table summarizes the estimated fair value of the tangible and intangible assets acquired and liabilities assumed (in thousands):

Accounts receivable	$	7,550
Other assets		590
Identifiable intangibles		9,050
Total assets acquired		17,190
Total liabilities assumed		2,556
Net assets acquired		14,634
Goodwill		30,221
Total purchase price	$	44,855

Purchase price for CrossView is as follows (in thousands, except share data and stock price):

Number of shares of common stock issued		553,223
Multiplied by PFSweb, Inc.'s stock price	$	11.40
Share consideration	$	6,307
Aggregate cash payments		30,740
Performance-based contingent payments (based on estimated fair value at acquisition date)		9,195
Post-closing balance sheet reconciliation adjustment		(1,387	)
Total purchase price	$	44,855

The excess of the purchase price over the fair value of the net identifiable assets acquired and liabilities assumed was allocated to goodwill. Total goodwill of $30.2 million, which, given the structure of the acquisition, is expected to be deductible for tax purposes over 15 years is not being amortized and is subject to an annual impairment test using a fair-value-based approach.

Acquisition of Moda

On June 11, 2015, PFSweb, Inc. acquired the outstanding capital stock of Moda, an eCommerce system integrator and consultancy that provides unique digital experiences for fashion brands and retailers through its primary operations in London, U.K. Consideration paid for the shares included an initial £650,000 (approximately $1.0 million) cash payment and 16,116 unregistered shares of Company stock (approximately $0.2 million in value as of the acquisition date). The purchase agreement provided for earn-out payments (“Moda Earn-out Payments”) based on Moda’s achievement of certain financial targets, subject to possible offsets for indemnification and other claims arising under the purchase agreement. Moda did not achieve the financial targets so the Company did not make any payments or record any liability as of December 31, 2017 or December 31, 2016 applicable to the Moda Earn-out Payments.

The transaction was accounted for using the purchase method of accounting for business combinations and, accordingly, the assets acquired and liabilities assumed, including an allocation of purchase price, and the results of operations of Moda, including the amortization of acquired intangible assets, have been included in the Company’s consolidated financial statements since the date of acquisition, which for 2015 included $1.2 million of service fee revenue and $0.2 million of net loss.

The Company determined fair value using a combination of the discounted cash flow, market multiple and market capitalization valuation methods. The following table summarizes the estimated fair value of the tangible and intangible assets acquired and liabilities assumed (in thousands):

Share consideration contingent payments	$	235
Aggregate cash payments		1,005
Performance-based contingent payments (based on fair value at acquisition date)		240
Total purchase price	$	1,480

The excess of the purchase price over the fair value of the net identifiable assets acquired and liabilities assumed was allocated to goodwill. Total goodwill of $1.3 million, none of which is deductible for tax purposes, is not being amortized but is subject to an annual impairment test using a fair-value-based approach.

The unaudited pro forma total revenues and pro forma net loss are not necessarily indicative of the consolidated results of operations for future periods or the results of operations that would have been realized had the Company consolidated CrossView and Conexus during the periods noted. Unaudited pro forma results of operations assuming the Moda acquisition had taken place at the beginning of 2015 are not provided because the historical operating results of Moda were not significant and pro forma results would not be significantly different from reported results for the periods presented.

Acquisition-Related Expenses

The acquisitions are expected to enhance the overall product and service offering of the Company to its existing clients and customers, as well as support anticipated growth opportunities. The Company recorded $1.5 million and $3.5 million of acquisition-related expenses during the years ended December 31, 2016 and 2015, which are included in selling, general and administrative expenses in the consolidated statements of operations.

Goodwill and Identifiable Intangibles, Net

6. Goodwill and Identifiable Intangibles, Net

Goodwill acquired through acquisitions is recognized as part of the PFSweb segment. During 2017, goodwill decreased by $0.5 million due to the impact of foreign currency translation for 2017 and prior periods. During 2016, the amount of goodwill increased by $6.4 million due to acquisitions.

The Company performed its annual goodwill impairment test during the fourth quarter of 2017, 2016 and 2015 by completing a Step 0 test. During each year, the Company determined that it was not more likely than not that the reporting unit’s fair value was less than its carrying value and, therefore, did not complete the prescribed two-step goodwill impairment test and thus the Company did not record any goodwill impairment during 2017, 2016 and 2015.

The following table presents the gross carrying value and accumulated amortization for identifiable intangibles (in thousands):

Definite-Lived Identifiable Intangible Asset Amortization

The changes in the net carrying values of identifiable intangible assets during 2017, 2016 and 2015 were primarily due to amortization expense of $3.4 million, $4.0 million and $3.0 million, respectively, as well as the impact of foreign currency translation. Amortization expense is included in selling, general and administrative expenses in 2017, 2016 and 2015, respectively, in the consolidated statements of operations.

Debt Disclosure [Abstract]
Inventory Financing	7. Inventory Financing Supplies Distributors has a short-term credit facility with IBM Credit LLC (“IBM Credit Facility”) to finance its purchase and distribution of Ricoh products in the United States, providing financing for eligible Ricoh inventory and certain receivables up to $13.0 million. The agreement has no stated maturity date and provides either party the ability to exit the facility following a 90-day notice. Given the structure of this facility and as outstanding balances, which represent inventory purchases, are repaid within twelve months, the Company has classified the outstanding amounts under this facility, which were $7.1 million and $7.3 million as of December 31, 2017 and 2016, respectively, as trade accounts payable in the consolidated balance sheets. As of December 31, 2017, Supplies Distributors had $0.4 million of available credit under this facility. The credit facility contains cross default provisions, various restrictions upon the ability of Supplies Distributors to, among other things, merge, consolidate, sell assets, incur indebtedness, make loans and payments to related parties (including entities directly or indirectly owned by PFSweb, Inc.), provide guarantees, make investments and loans, pledge assets, make changes to capital stock ownership structure and pay dividends. The credit facility also contains financial covenants, such as annualized revenue to working capital, net profit after tax to revenue, and total liabilities to tangible net worth, as defined, and is secured by certain of the assets of Supplies Distributors, as well as a collateralized guaranty of PFSweb. Additionally, PFSweb is required to maintain a minimum Subordinated Note receivable balance from Supplies Distributors of $2.5 million. Borrowings under the credit facility accrue interest, after a defined free financing period, at prime rate plus 0.5% (4.75% as of December 31, 2017). The facility also includes a monthly service fee. As of December 31, 2017, the Company was in compliance with all financial covenants. Pursuant to IBM Credit Facility, Supplies Distributors is restricted from making any distributions to PFSweb if, after giving affect thereto, Supplies Distributors’ would be in noncompliance with its financial covenants. Supplies Distributors has received lender approval to pay approximately $1.7 million of dividends in 2018. Supplies Distributors paid dividends to PFSweb of $1.7 million, $1.1 million and $0.9 million in 2017, 2016 and 2015, respectively, which eliminate upon consolidation.

U.S. Credit Agreement

In August 2015, PFSweb, Inc. and its U.S. subsidiaries entered into a credit agreement (“Credit Agreement”) with Regions Bank, as agent for itself and one or more future lenders (the “Lenders”). The Credit Agreement replaced the Company’s previously existing credit facilities with Wells Fargo Bank, National Association (“Wells Fargo”) and Comerica Bank (“Comerica”). During 2015, as contemplated by the Credit Agreement, the Credit Agreement was expanded to also include Bank of America N.A. and HSBC Bank USA, National Association. Under the Credit Agreement, and subject to the terms set forth therein, the Lenders have agreed to provide PFS with a revolving loan facility for up to $32.5 million and a term loan facility for up to $30 million through August 5, 2020. Subject to the terms of the Credit Agreement, PFS has the ability to increase the total loan facilities to $75 million. Availability under the revolving loan facility may not exceed a borrowing base of eligible accounts receivable (as defined). As of December 31, 2017, the Company had $19.3 million of available credit under the revolving loan facility. Advances under the revolving loan portion of the Credit Agreement are due and payable on August 5, 2020. Term loan advances amortize during the five year term of the Credit Agreement based upon scheduled percentage payments with the then remaining outstanding balance (potentially up to 65% of the amount borrowed) due on August 5, 2020. Borrowings under the Credit Agreement accrue interest at a variable rate based on prime rate or Libor, plus an applicable margin. As of December 31, 2017 and 2016, the weighted average interest rate on the revolving loan facility was 4.65% and 3.25%, respectively. As of December 31, 2017 and 2016, the weighted average interest rate on the term loan facility was 4.05% and 3.32%, respectively. In connection with the Credit Agreement, the Company paid $0.7 million of fees, which are being amortized through the life of the Credit Agreement and are reflected as a net reduction in debt. The Credit Agreement is secured by a lien on substantially all of the assets of Company and its U.S. subsidiaries and a pledge of 65% of the shares of certain of the Company’s foreign subsidiaries. The Credit Agreement contains cross default provisions, various restrictions upon the Company’s ability to, among other things, merge, consolidate, sell assets, incur indebtedness, make loans and payments to subsidiaries, affiliates and related parties, make capital expenditures, make investments and loans, pledge assets, make changes to capital stock ownership structure, as well as financial covenants, as defined, of a minimum consolidated fixed charge ratio and a maximum consolidated leverage ratio. In June 2016, PFSweb also entered into a Master Agreement with Regions Bank to provide equipment loans financing for certain capital expenditures.

Debt Covenants

To the extent the Company or any of its subsidiaries fail to comply with its covenants applicable to its debt or inventory financing obligations, including the periodic financial covenant requirements, such as profitability and cash flow, and required level of shareholders’ equity or net worth (as defined), the Company would be required to obtain a waiver from the lender or the lender would be entitled to accelerate the repayment of any outstanding credit facility obligations, and exercise all other rights and remedies, including sale of collateral and enforcement of payment under the Company parent guarantee. Any acceleration of the repayment of the credit facilities may have a material adverse impact on the Company’s financial condition and results of operations and no assurance can be given that the Company would have the financial ability to repay all of such obligations. At December 31, 2017 and 2016, the Company had restricted net assets of approximately $63.3 million and $71.6 million, respectively. As of December 31, 2017, the Company was in compliance with all debt covenants.

Master Lease Agreements

The Company has various agreements that provide for leasing or financing transactions of equipment and other assets and will continue to enter into such arrangements as needed to finance the purchasing or leasing of certain equipment or other assets. Borrowings under these agreements, which generally have terms of three to five years, are generally secured by the related equipment, and in certain cases, by a Company parent guarantee.

Stock and Stock Options

9. Stock and Stock Options

Preferred Stock Purchase Rights

On June 8, 2000, the Company’s Board of Directors declared a dividend distribution of one preferred stock purchase right (a “Right”) for each share of the Company’s common stock outstanding on July 6, 2000 and each share of common stock issued thereafter. Each Right entitles the registered shareholders to purchase from the Company one one-thousandth of a share of preferred stock at an exercise price of $65, subject to adjustment. The Rights are not currently exercisable, but would become exercisable if certain events occurred relating to a person or group acquiring or attempting to acquire 20 percent or more of the Company’s outstanding shares of common stock. The Rights expire 30 days after the Company’s 2018 Annual Meeting unless continuation of the Rights Agreement is approved by the stockholders of the Company at the 2018 Annual Meeting.

Stock Compensation Plans

The Company has an Employee Stock and Incentive Plan (the “Employee Plan”), as amended and restated, under which an aggregate of 5,942,340 shares of common stock have been authorized for issuance. The Employee Plan provides for the granting of incentive awards to directors, executive management, key employees, and outside consultants of the Company in a variety of forms of equity-based incentive compensation, such as the award of an option, stock appreciation right, restricted stock award, restricted stock unit, deferred stock unit, among other stock-based awards. The Company has historically issued service-based restricted stock and unit awards, performance-based and market-based stock and unit awards (collectively “Restricted Shares”), and stock options. The Company uses newly issued shares of common stock to satisfy awards under the Plan.

The Company issues Restricted Shares to the Company’s executives and senior management, pursuant to which such employees are eligible to receive future grants of shares of the Company’s stock subject to various vesting and/or performance criteria. The weighted average fair value per share of Restricted Shares granted during the years ended December 31, 2017, 2016 and 2015 was $6.43, $8.73 and $10.45, respectively. The total fair value of Restricted Shares vested under the Employee Plans was $0.5 million, $0.9 million and $3.9 million during the years ended December 31, 2017, 2016 and 2015, respectively.

The underlying stock certificates for the Restricted Shares that vested December 31, 2017 are expected to be issued during the quarter ending March 31, 2018. The underlying stock certificates for the Restricted Shares that vested December 31, 2016 were issued during the quarter ended March 31, 2017. Based on the Company’s 2016 financial performance, no Restricted Shares were issued under the 2016 Performance Based Share Awards.

Total stock-based compensation expense was $3.3 million, $2.1 million and $4.6 million for the years ended December 31, 2017, 2016 and 2015, respectively, and was included as a component of selling, general and administrative expenses in the consolidated statements of operations. As of December 31, 2017, there is $2.6 million of total unrecognized compensation costs related to non-vested share-based compensation arrangements granted under the Plan, which is expected to be recognized over a remaining weighted average period of approximately 1.5 years. This expected cost does not include the impact of any future stock-based compensation awards.

As of December 31, 2017, there were 860,256 shares available for future grants under the Plan. Each stock option or stock appreciation right award granted reduces the total shares available for grant by one share, while each award granted other than in the form of a stock option or stock appreciation right reduces the shares available for grant by 1.22 shares.

Stock Options

The rights to purchase shares under employee stock option agreements issued under the Plan typically vest over a three-year period, one-twelfth each quarter. Stock options must be exercised within 10 years from the date of grant. Stock options are generally issued such that the exercise price is equal to the market value of the Company’s common stock at the date of grant.

The following tables summarize stock option activity under the Plans:

							Weighted
							Average
					Weighted		Remaining		Aggregate
					Average		Contractual		Intrinsic
					Exercise		Life (in		Value (in

Exercisable and expected to vest, December 31, 2017		1,027,181		$1.46 - $15.36	$	7.83		5.6	$	1.5

The weighted average fair value per share of options granted during the years ended December 31, 2017, 2016 and 2015 was $3.58, $5.88 and $7.91, respectively. The total intrinsic value of options exercised under the Stock Option Plans was $0.5 million, $1.9 million and $3.4 million during the years ended December 31, 2017, 2016 and 2015, respectively.

The fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model with the following assumptions used for grants of options under the Plans:

	Year Ended
	December 31,
	2017		2016		2015
Expected dividend yield		—		—		—
Expected stock price volatility	46% - 50%		50% - 63%		63% - 68%
Risk-free interest rate	2.0% - 2.2%		1.4% - 1.9%		1.5% - 1.8%
Expected life of options (years)	6		6		6

The Black-Scholes option valuation model requires the input of highly subjective assumptions, including the expected life of the stock-based award and stock-price volatility. The assumptions listed above represent management’s best estimates, but these estimates involve inherent uncertainties and the application of management judgment. As a result, if other assumptions had been used, the Company’s recorded and pro forma stock-based compensation expense could have been different. In addition, the Company is required to estimate the expected forfeiture rate and only recognize expense for those shares expected to vest. If the Company’s actual forfeiture rate is materially different from its estimate, the share-based compensation expense could be materially different. The Company calculates the expected stock price volatility using the Company’s historical stock price during the expected term immediately preceding a stock option grant date. The Company has not paid dividends in the past and does not anticipate paying dividends in the future. The Company uses the risk-free interest rates of United States Treasury securities for a comparable term as the expected life of a stock option. The expected life of options has been computed using the simplified method, which the Company uses as it does not believe it has established a consistent exercise pattern to accurately estimate the expected term of stock options.

Service-Based Restricted Stock and Unit Awards

The Company’s service-based restricted stock and unit awards are valued at the quoted market price of the Company’s common stock as of the date of grant and vest over a range of two to four years. Shares that do not vest on a scheduled vesting date due to a failure to satisfy vesting or performance criteria are forfeited and do not vest in future periods.

The following table summarizes the service-based restricted stock and unit award activity for the year ended December 31, 2017:

				Weighted
				Average
				Grant Date
	Shares			Fair Value per Share
Unvested restricted stock at December 31, 2016		14,763		$	11.26

Canceled		(22,204	)	$	6.74
Unvested restricted stock at December 31, 2017		112,569		$	6.47

Performance-Based Restricted Stock and Unit Awards

Pursuant to the Employee Plan, the Company grants restricted stock and unit awards that vest upon reaching certain performance targets, and individual performance goals, which historically have been based on the Company’s financial performance, Company operating income and other financial metrics for the current and/or future years. Such awards generally are subject to annual vesting from three to four years based upon continued employment and the achievement of the defined performance criteria. If the target set forth in the award agreement is not met, none of the related shares will vest and any compensation expense previously recognized will be reversed. The actual number of shares that will ultimately vest is dependent upon achieving the performance condition or other conditions set forth in the award agreement. The Company recognizes stock-based compensation expense related to performance awards based upon our determination of the likelihood of achieving the performance target or targets at each reporting date, net of estimated forfeitures.

The following table summarizes the performance-based restricted stock and unit award activity for the year ended December 31, 2017:

				Weighted

Canceled		(223,451	)	$	7.11
Unvested restricted stock at December 31, 2017		65,254		$	6.40

Market-Based Restricted Stock and Unit Awards

Pursuant to the Employee Plan, the Company grants restricted stock and unit awards that vest upon the achievement of certain defined total stockholder return targets using the companies in the Russell Micro Cap Index as a comparative group for current and/or future years. Such awards generally are subject to annual vesting from three to four years based upon continued employment and the achievement of the defined performance criteria. The actual number of shares that will ultimately vest is dependent upon achieving the performance condition or other conditions set forth in the award agreement. Shares that do not vest on a scheduled vesting date due to a failure to satisfy vesting criteria are forfeited and do not vest in future periods. The Company reverses previously recognized compensation cost for market-based restricted stock unit awards only if the requisite service is not rendered.

The following table summarized the market-based restricted stock and unit award activity for the year ended December 31, 2017:

				Weighted
				Average
				Grant Date
	Shares			Fair Value per Share
Unvested restricted stock at December 31, 2016		63,128		$	7.83

Canceled		(47,109	)	$	7.37
Unvested restricted stock at December 31, 2017		204,750		$	5.95

The fair value of each market-based restricted stock and unit award grant is estimated on the date of grant using a Monte-Carlo simulation with the following assumptions used for grants under the Plans:

Stock Units

Each non-employee Director of the Company’s Board of Directors (the “Board”) receives a quarterly retainer (the “Retainer”) of $25,000, payable on or about the first day of each quarter, through the issuance of an equity-based award (an “Award”) under the Employee Plan in the form of a Deferred Stock Unit (a “DSU”). The number of DSUs is determined by dividing the Retainer by the immediately preceding closing price of the Common Stock. Each DSU represents the right to receive an equal number of shares of Common Stock upon the retirement, resignation or termination of service from the Board.

The following table summarizes the DSU activity for the year ended December 31, 2017:

On December 22, 2017, the United States government enacted the Tax Cuts and Jobs Act, commonly referred to as the Tax Reform Act. The Tax Reform Act includes significant changes to the U.S. income tax system, including, but not limited to: a federal corporate rate reduction from 35% to 21%; limitations on the deductibility of interest expense and executive compensation; repeal of the Alternative Minimum Tax (“AMT”); full expensing provisions related to business assets; creation of new minimum taxes, such as the base erosion anti-abuse tax (“BEAT”) and Global Intangible Low Taxed Income (“GILTI”) tax; and the transition of U.S. international taxation from a worldwide tax system to a modified territorial tax system, which will result in a one time U.S. tax liability on those earnings which have not previously been repatriated to the U.S. (the “Transition Tax”). The provisional impacts of this legislation are outlined below:

•

Beginning January 1, 2018, the U.S. corporate income tax rate will be 21%. The Company is required to recognize the impacts of this rate change on its deferred tax assets and liabilities in the period enacted. We remeasured certain deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is generally 21%. However, we are still analyzing certain aspects of the Tax Reform Act and refining our calculations, which could potentially affect the measurement of these balances or potentially give rise to new deferred tax amounts. The provisional amount related to the remeasurement of our deferred tax balance was $12.1 million that was mostly offset by a change in the valuation allowance, except for a $0.6 million benefit that was recorded to our income statement related to tax amortization of goodwill.

•

The Transition Tax on unrepatriated foreign earnings is a tax on previously untaxed accumulated and current earnings and profits ("E&P") of the Company's foreign subsidiaries. To determine the amount of the Transition Tax, the Company must determine, among other factors, the amount of post-1986 E&P of its foreign subsidiaries, as well as the amount of non-U.S. income taxes paid on such earnings. Based on the Company’s reasonable estimate of the Transition Tax, there is no provisional Transition Tax expense. The Company has not completed accounting for the income tax effects of the transition tax and is continuing to evaluate this provision of the Tax Reform Act.

•

The Tax Reform Act creates a new requirement that GILTI income earned by foreign subsidiaries must be included currently in the gross income of the U.S. shareholder. Due to the complexity of the new GILTI tax rules, the Company is continuing to evaluate this provision of the Tax Reform Act. Under U.S. GAAP, the Company is permitted to make an accounting policy election to either treat taxes due on future inclusions in U.S. taxable income related to GILTI as a current period expense when incurred or to factor such amounts into the Company's measurement of its deferred taxes. The Company has not yet completed its analysis of the GILTI tax rules and is not yet able to reasonably estimate the effect of this provision of the Tax Reform Act or make an accounting policy election for the accounting treatment whether to record deferred taxes attributable to the GILTI tax. The Company has not recorded any amounts related to potential GILTI tax in the Company’s consolidated financial statements.

The income tax effects recorded in the Company’s consolidated financial statements as a result of the Tax Reform Act are provisional in accordance with the Securities and Exchange Commission’s Staff Accounting Bulletin number 118 (“SAB 118”) as the Company has not yet completed its evaluation of the impact of the new law. SAB 118 allows for a measurement period of up to one year after the enactment date of the Tax Reform Act to finalize the recording of the related tax impacts.

The preliminary net tax effects recorded may differ in the future due to changes in the interpretations of the Tax Reform Act, legislative action, and changes to estimates we have utilized to calculate the tax impact. We expect to finalize the tax analysis related to the Tax Reform Act with the filing of our tax return and record any differences between the final and provisional amounts in the 2018 fourth quarter at that time, if any.

Management believes that PFSweb has not established a sufficient history of earnings, on a stand-alone basis, to support the more likely than not realization of certain deferred tax assets in excess of existing taxable temporary differences. A valuation allowance has been provided for the majority of these net deferred income tax assets as of December 31, 2017 and 2016. The remaining net deferred tax assets at both December 31, 2017 and 2016 primarily relate to the Company’s European operations and certain state tax benefits and are included in other non-current and current assets on the consolidated balance sheets. At December 31, 2017, net operating loss (“NOL”) carryforwards relate to taxable losses of PFSweb’s Canadian subsidiary totaling approximately $3.6 million and PFSweb’s U.S. subsidiaries totaling approximately $61.2 million that expire at various dates from 2019 through 2036. The U.S. NOL also includes approximately $4.4 million of NOL created before February 2006 subject to annual limits of $1.4 million, and $0.2 million acquired September 2014 subject to annual limits of $0.1 million under IRS Section 382.

The Company evaluates its tax positions for potential liabilities associated with unrecognized tax benefits. The Company does not expect to record unrecognized tax benefits in the next twelve months.

For federal income tax purposes, tax years that remain subject to examination include years 2014 through 2017. However, the utilization of net operating loss carryforwards that arose prior to 2014 remains subject to examination through the years such carryforwards are utilized. For Europe, tax years that remain subject to examination include years 2015 to 2017. For Canada, tax years that remain subject to examination include years 2009 to 2017, depending on the subsidiary. For state income tax purposes, the tax years that remain subject to examination include years 2013 to 2017, depending upon the jurisdiction in which the Company files tax returns. The Company and its subsidiaries have various income tax returns in the process of examination. The Company does not expect these examinations will result in unrecognized tax benefits.

Earnings Per Share [Abstract]
Earnings Per Share	11. Earnings Per Share Basic and diluted net loss per share are computed by dividing net loss by the weighted-average number of common shares outstanding for the reporting period. The following equity awards have been excluded from the calculation of diluted net loss per share as their effect would be anti-dilutive: 1.0 million, 1.2 million and 1.3 million stock options for the years ended December 31, 2017, 2016 and 2015, respectively; 0.4 million, 0.2 million and 0.7 million performance shares and restricted stock units for the years ended December 31, 2017, 2016 and 2015, respectively; and 0.2 million, 0.1 million and 0.1 million deferred stock units for the years ended December 31, 2017, 2016 and 2015, respectively.

The Company leases facilities, warehouse and office space and transportation and other equipment under operating leases expiring in various years through 2026. In most cases, management expects that, in the normal course of business, leases will be renewed or replaced by other similar leases. The Company’s facility leases generally contain one or more renewal options.

Minimum future annual rental payments under non-cancelable operating leases having original terms in excess of one year are as follows (in thousands):

Total rental expense under operating leases approximated $11.3 million, $11.2 million and $8.2 million for the years ended December 31, 2017, 2016 and 2015, respectively.

The Company received municipal tax abatements in certain locations. In prior years, the Company received notice from a municipality that it did not satisfy certain criteria necessary to maintain the abatements and that the municipal authority planned to make an adjustment to the Company’s tax abatement. The Company disputed the adjustment and such dispute has been settled with the municipality. However, the amount of additional property taxes to be assessed against the Company and the timing of the related payments has not been finalized. As of December 31, 2017, the Company believes it has adequately accrued for the expected assessment.

In April 2010, a sales employee of eCOST.com, Inc. (“eCOST”, the former name of Retail Connect) was charged with violating various federal criminal statutes in connection with the sales of eCOST products to certain customers, and approximately $0.6 million held in an eCOST deposit account was seized and turned over to the Office of the U.S. Attorney in connection with such activity. In August 2012, the employee pleaded guilty to a misdemeanor. Neither the Company nor eCOST were charged with any criminal activity. During 2015, the matter was settled, and $0.2 million of the subject funds were released to the Company. The Company recorded a $0.4 million expense, included as a component of selling, general and administrative expenses in the consolidated statements of operations, to properly reflect the settlement.

The Company is subject to claims in the ordinary course of business, including claims of alleged infringement by the Company or its subsidiaries of the patents, trademarks and other intellectual property rights of third parties. PFS is generally required to indemnify its service fee clients against any third party claims asserted against such clients alleging infringement by PFS of the patents, trademarks and other intellectual property rights of third parties. In the opinion of management, any liabilities resulting from these claims, would not have a material adverse effect on the Company’s financial position or results of operations.

Quarterly Data - Seasonality (Unaudited)

15. Quarterly Data – Seasonality (Unaudited)

The seasonality of the Company’s business is dependent upon the seasonality of its clients’ business and their sale of products. Management believes that with the Company’s current client mix and their clients’ business volumes, the Company’s service fee revenue business activity and pass-through revenue is at its highest in the quarter ended December 31 subject to transactional volumes of its clients. Supplier Distributors’ product revenue business activity is generally expected to be more evenly distributed throughout the year. The Company’s fourth quarter accounted for 28.4% and 30.6% of its net revenues for the years ended December 31, 2017 and 2016, respectively. The estimated performance-based liability related to the CrossView acquisition was increased by $3.7 million during the three months ended December 31, 2016 based on CrossView’s 2016 financial performance and updated projections for 2017.

Significant Accounting Policies (Policies)	12 Months Ended
Significant Accounting Policies (Policies)	Dec. 31, 2017
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation All intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America (“US GAAP”) requires management to make judgments, estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and disclosure of contingent assets and liabilities. The recognition and allocation of certain revenues and selling, general and administrative expenses in these consolidated financial statements also require management estimates and assumptions. Estimates and assumptions about future events and their effects cannot be determined with certainty. The Company bases its estimates on historical experience and various other assumptions believed to be applicable and reasonable under the circumstances. These estimates may change as new events occur, as additional information is obtained and as the operating environment changes. These changes have been included in the consolidated financial statements as soon as they became known. In addition, management is periodically faced with uncertainties, the outcomes of which are not within its control and will not be known for prolonged periods of time. Based on a critical assessment of accounting policies and the underlying judgments and uncertainties affecting the application of those policies, management believes the Company’s consolidated financial statements are fairly stated in accordance with US GAAP, and provide a fair presentation of the Company’s financial position and results of operations.
Revenue and Cost Recognition	Revenue and Cost Recognition The Company derives revenue primarily from services provided under contractual arrangements with its clients or from the sale of products under its distributor agreements. The following revenue recognition policies define the manner in which the Company accounts for sales transactions. The Company recognizes revenue when persuasive evidence of a sales arrangement exists, product shipment or delivery has occurred or services have been rendered, the sales price or fee is fixed or determinable, and collectability is reasonably assured. In instances where revenue is derived from sales of third-party vendor products or services, the Company records revenue on a gross basis when the Company is a principal to the transaction and net of costs when the Company is acting as an agent between the customer or client and the vendor. The Company considers several factors to determine whether it is a principal or an agent, most notably whether the Company is the primary obligor to the vendor or customer, has established its own pricing and has inventory and credit risks, if applicable. Service Fee Revenue Activity The Company’s service fee revenue primarily relates to its distribution services, order management/customer care services, professional digital agency and technology services. The Company typically charges its service fee revenue on either a cost-plus basis, a percent of shipped revenue basis, on a time and materials, project or retainer basis for professional services, or a per transaction basis, such as a per item basis for fulfillment services or a per labor hour basis for web-enabled customer contact center services. Additional fees are billed for other services. The Company evaluates its contractual arrangements to determine whether or not they include multiple service elements. Revenue recognition is determined for the separate service elements of the contract in accordance with the requirements of Accounting Standards Codification (“ASC”) 605, “Revenue Recognition.” A deliverable constitutes a separate unit of accounting when it has standalone value and there are no return rights or other contingencies present for the delivered elements. The Company allocates revenue to each element based on estimated selling price. Each of the Company’s client contracts, and the related services, is unique, with individual needs and criteria customized for each client. Each client engagement is scoped and priced separately and as such the Company is not able to establish vendor specific objective evidence of fair value for its services, nor is third-party evidence available to establish stand-alone selling prices. Accordingly, the Company uses management’s best estimate of selling price for the deliverables. The Company establishes its estimates considering internal factors, such as margin objectives, pricing practices and controls, as well as market conditions, such as competitor pricing strategies. Distribution services relate primarily to inventory management, product receiving, warehousing and fulfillment (i.e., picking, packing and shipping) and facilities and operations management. Service fee revenue for these activities is recognized as earned, which is either (i) on a per transaction basis or (ii) at the time of product fulfillment, which occurs at the completion of the distribution services. Order management/customer care services relate primarily to taking customer orders for the Company’s clients’ products. These services also include addressing customer questions related to orders, as well as cross-selling/up-selling activities. Service fee revenue for this activity is recognized as the services are rendered. Fees charged to the client are on a per transaction basis based on either (i) a pre-determined fee per order or fee per telephone minutes incurred, (ii) a per dedicated agent fee, or (iii) are included in the product fulfillment service fees that are recognized on product shipment. Professional consulting and technology service revenues primarily relate to design, implementation, service and support of eCommerce platforms, website design and solutions and quality control for the Company’s clients. Additionally, the Company provides digital agency services that enable client marketing programs to attract new customers, convert buyers and increase website value. These fees are typically charged on either a per labor hour or transaction basis, a dedicated resource model, a fixed price arrangement, or a percent of merchandise shipped basis. Service fee revenue for this activity is generally recognized as the services are rendered. The Company performs front-end set-up and integration services to support client eCommerce platforms and websites. When the Company determines these front-end set-up and integration services do not meet the criteria for recognition as a separate unit of accounting, the Company defers the start-up fees received and the related costs, and recognizes them over the expected performance period. When the Company determines these front-end set-up and integration services do meet the criteria for recognition as a separate unit of accounting, for time and material arrangements, the Company recognizes revenue as services are rendered and costs as they are incurred. For fixed-price arrangements, the Company uses the completed contract method to recognize revenues and costs if reasonable and reliable cost estimates for a project cannot be made. If reasonable and reliable costs estimates for a project can be made, the Company recognizes revenue over the expected performance period on a proportional performance basis, as determined by the relationship of actual costs incurred compared to the estimated total contract costs. The Company’s billings for reimbursement of out-of-pocket expenses, including travel and certain third-party vendor expenses, such as shipping and handling costs and telecommunication charges, are included in pass-through revenue. The related reimbursable costs are reflected as cost of pass-through revenue. The Company’s cost of service fee revenue, representing the cost to provide the services described above, is recognized as incurred. Cost of service fee revenue also includes certain costs associated with technology collaboration and ongoing technology support that include maintenance, web hosting and other ongoing programming activities. These activities are primarily performed to support the distribution and order management/customer care services and are recognized as incurred. Product Revenue Activity Depending on the terms of the customer arrangement, Supplies Distributors recognizes product revenue and product cost either upon the shipment of product to customers or when the customer receives the product. Supplies Distributors permits its customers to return product for credit against other purchases, which include returns for defective products (that Supplies Distributors then returns to the manufacturer) and incorrect shipments. Supplies Distributors provides a reserve for estimated returns and allowances and offers terms to its customers that it believes are standard for its industry. Freight costs billed to customers are reflected as components of product revenue. Freight costs incurred are recorded as a component of cost of product revenue. Under its distributor agreements, Supplies Distributors bills Ricoh for reimbursements of certain expenses, including: pass-through customer marketing programs, including rebates and coop funds; certain freight costs; direct costs incurred in passing on any price decreases offered by Ricoh to Supplies Distributors or its customers to cover price protection and certain special bids; the cost of products provided to replace defective product returned by customers; and certain other expenses as defined. Supplies Distributors records these reimbursable amounts as they are incurred as other receivables in the consolidated balance sheet with a corresponding reduction in either inventory or cost of product revenue. Supplies Distributors also records pass-through customer marketing programs as a reduction of both product revenue and cost of product revenue. Deferred Revenues and Deferred Costs The Company primarily performs its distribution services, order management, customer care and certain other services under multiple year contracts, certain of which include early termination provisions, and clients are obligated to pay for services performed. In conjunction with these long-term contracts, the Company sometimes receives start-up fees to cover its implementation costs, including certain technology infrastructure and development costs. When the Company determines that these start-up and integration activities do not meet the criteria for recognition as a separate unit of accounting, the Company defers the start-up fees received, and the related costs, and recognizes them over the expected performance period. The amortization of deferred revenue is included as a component of service fee revenue. The amortization of deferred implementation costs is included as a cost of service fee revenue. To the extent implementation costs for non-technology infrastructure and development exceed the corresponding fees received, the excess costs are expensed as incurred. Current and non-current deferred implementation costs, excluding technology and development costs, are a component of prepaid expenses and other current assets and other assets, respectively.
Concentration of Business and Credit Risk	Concentration of Business and Credit Risk During 2017 and 2016, no product customer or service fee client relationships represented more than 10% of the Company’s consolidated total net revenues. During 2015, one service fee client relationship, the United States Mint, represented approximately 11%, or $31.2 million, of the Company’s consolidated total net revenues. As of December 31, 2017, no client exceeded 10% of the Company’s total accounts receivable. As of December 31, 2016, one client exceeded 10% of the Company’s consolidated accounts receivable.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash equivalents are defined as short-term highly liquid investments with original maturities, when acquired, of three months or less. At times, the Company has cash balances in domestic bank accounts that exceed Federal Deposit Insurance Corporation insured limits. The Company has not experienced any losses related to these cash concentrations.
Accounts Receivable	Accounts Receivable The Company recognizes revenue and records trade accounts receivable, pursuant to the methods described above, when collectability is reasonably assured. Collectability is evaluated in the aggregate and on an individual customer or client basis taking into consideration payment due date, historical payment trends, current financial position, results of independent credit evaluations and payment terms. Related reserves are determined by either using percentages applied to certain aged receivable categories based on historical results, reevaluated and adjusted as additional information is received, or a specific identification method. After all attempts to collect a receivable have failed, the receivable is written off against the allowance for doubtful accounts.
Other Receivables	Other Receivables Other receivables primarily include amounts due from Ricoh for costs incurred by the Company under the distributor agreements and value added tax receivables.
Inventories	Inventories Inventories (all of which are finished goods) are stated at the lower of weighted average cost and net realizable value. The Company establishes inventory reserves based upon estimates of declines in values due to inventories that are slow moving or obsolete, excess levels of inventory or values assessed at lower than cost. Supplies Distributors assumes responsibility for slow-moving inventory under its Ricoh distributor agreements, subject to certain termination rights, but has the right to return product rendered obsolete by engineering changes, as defined. In the event PFSweb, Supplies Distributors and Ricoh terminate the distributor agreements, the agreements provide for the parties to mutually agree on a plan of disposition of Supplies Distributors’ then existing inventory.
Property and Equipment	Property and Equipment The Company makes judgments and estimates in conjunction with the carrying value of property and equipment, including amounts to be capitalized, depreciation and amortization methods and useful lives. Property and equipment are stated at cost and are depreciated using the straight-line method over the estimated useful lives of the respective assets. Capitalized implementation costs are depreciated over the respective client expected performance period. Leasehold improvements are amortized over the shorter of the useful life of the related asset or the remaining lease term. When events or changes in circumstances indicate that the carrying amount of our property and equipment might not be recoverable, the expected future undiscounted cash flows from the asset are estimated and compared with the carrying amount of the asset. If the sum of the estimated undiscounted cash flows is less than the carrying amount of the asset, an impairment loss is recorded. The impairment loss is measured by comparing the fair value of the asset with its carrying amount. Fair value is generally determined based on discounted cash flows or appraised values, as appropriate.
Business Combinations	Business Combinations The Company accounts for business combinations under the acquisition method of accounting, which requires the assets and liabilities to be recorded at their respective fair values as of the acquisition date in the consolidated financial statements. The determination of estimated fair value may require management to make significant estimates and assumptions. The purchase price is the fair value of the total consideration conveyed to the seller and the excess of the purchase price over the fair value of the acquired identifiable net assets, where applicable, is recorded as goodwill. The results of operations of an acquired business are included in the Company’s consolidated financial statements from the date of acquisition. Costs associated with the acquisition of a business are expensed in the period incurred.
Definite-Lived Intangible Assets	Definite-Lived Intangible Assets The Company’s definite-lived intangible assets are primarily comprised of non-compete agreements, trade names, customer relationships and developed technology. Definite-lived intangible assets are amortized over their estimated useful life and only tested for impairment whenever events or circumstances indicate that the carrying amount of an asset may not be recoverable. An impairment loss would be recognized when the carrying amount of the asset exceeds the estimated undiscounted future cash flows expected to result from the use of the asset and its eventual disposition. The impairment loss to be recorded would be the excess of the asset’s carrying value over its fair value. Fair value is determined using a discounted cash flow analysis or other valuation technique.
Goodwill	Goodwill Goodwill represents the excess of the purchase price over the fair value of the identifiable net assets acquired. Goodwill and other intangible assets with indefinite lives are not amortized to operations, but instead are reviewed for impairment at least annually in the fourth quarter, or more frequently when there is an indicator of impairment. Goodwill impairment exists when a reporting unit’s goodwill carrying value exceeds its implied fair value. The Company has no intangible asset with indefinite useful lives, other than goodwill. ASU Topic 350: Testing Goodwill for Impairment (“ASU Topic 350”) permits an entity to make a qualitative assessment of whether it is more likely than not that a reporting unit’s fair value is less than its carrying amount before applying a two-step goodwill impairment test. This qualified assessment is referred to as “Step 0.” When performing Step 0, an entity evaluates relevant events and circumstances, including but not limited to, macroeconomic conditions, industry and market conditions, overall financial performance, reporting unit specific events and entity specific events. If, after completing Step 0, an entity concludes that it is not likely that the fair value of the reporting unit is less than its carrying amount, it would not be required to perform a two-step impairment test for that reporting unit. In the event that the conclusion of Step 0 requires the two-step test, the first step compares the fair value of the reporting unit with its carrying value, including goodwill. If the fair value of the reporting unit is less than its carrying value, an indication of goodwill impairment exists for the reporting unit and the entity must perform step two of the impairment test. Under step two, an impairment loss is recognized for any excess of the carrying amount of the reporting unit’s goodwill over the implied fair value of that goodwill. The implied fair value of goodwill is determined by allocating the fair value of the reporting unit in a manner similar to a purchase price allocation and the residual fair value after this allocation is the implied fair value of the reporting unit goodwill. Fair value of the reporting unit is determined using a discounted cash flow analysis. If the fair value of the reporting unit exceeds its carrying value, step two does not need to be performed. An impairment loss is recognized to the extent that the carrying amount of goodwill exceeds its implied fair value. If the Company is required to perform the two-step test described in the preceding paragraph, it would determine fair value using generally accepted valuation techniques, including discounted cash flows and market multiple analyses. These types of analyses contain uncertainties because they require management to make assumptions and to apply judgment to estimate industry economic factors and the profitability of future business strategies. The Company’s valuation methodology for assessing impairment would require management to make judgments and assumptions based on historical experience and projections of future operating performance. If these assumptions differ materially from future results, the Company may record impairment charges in the future.
Foreign Currency Translation and Transactions	Foreign Currency Translation and Transactions The functional currency of each of the Company’s foreign subsidiaries is local currency. Assets and liabilities are translated at exchange rates in effect at the end of the period, and income and expense items are translated at the average exchange rates on a monthly basis. Translation adjustments are accumulated and reported as a component of accumulated other comprehensive income in the consolidated statements of shareholders’ equity. The Company includes currency gains and losses on short-term intercompany advances in the determination of net income and loss. The Company reports gains and losses on intercompany foreign currency transactions that are of a long-term investment nature as a component of accumulated other comprehensive income in the consolidated statements of shareholders’ equity.
Stock-Based Compensation	Stock-Based Compensation The Company uses stock-based compensation, including stock options, deferred stock units and other stock-based awards to provide long-term performance incentives for its executives, key employees and non-employee directors. From the service inception date to the grant date, the Company recognizes compensation cost for all share-based payments based on the reporting date fair value of the award. After the grant date, compensation cost is measured based on the grant date fair value. Depending on the conditions associated with the vesting of the award, compensation cost is recognized on a straight-line or graded basis, net of estimated forfeitures, over the requisite service period of each award. The Company records compensation cost as a component of selling, general and administrative expenses in the consolidated statements of operations. The Company estimates the fair value of each option grant on the date of grant using the Black-Scholes option-pricing model and estimates the compensation cost for certain of the awards that have a performance condition using a Monte-Carlo simulation. The estimated fair value for awards involves assumptions for expected dividend yield, stock price volatility, risk-free interest rates and the expected life of the award.
Income Taxes	Income Taxes Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established when necessary to reduce deferred tax assets to the amount more likely than not to be realized. The Company recognizes interest and penalties related to certain tax positions in income tax expense and monitors uncertain tax positions and recognizes tax benefits only when management believes the relevant tax positions would more likely than not be sustained upon examination.
Fair Value of Financial Instruments	Fair Value of Financial Instruments In accordance with ASC 825, Financial Instruments, fair value is determined utilizing a hierarchy of valuation techniques. The three levels of the fair value hierarchy are as follows: Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2: Inputs, other than quoted prices, that are observable for the asset or liability, either directly or indirectly; these include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. Level 3: Unobservable inputs that reflect the reporting entity’s own assumptions. The carrying value of the Company’s financial instruments, which include cash and cash equivalents, accounts receivable, accounts payable, debt and capital lease obligations, approximate their fair values at December 31, 2017 and 2016 based on short terms to maturity or current market prices and interest rates or observable inputs such as quoted prices in active markets. Nonrecurring Fair Value Measurements The purchase price of business acquisitions is allocated to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values on the acquisition dates, with any excess recorded as goodwill. The Company utilizes Level 3 inputs in the determination of the initial fair value of assets and liabilities. Non-financial assets such as goodwill, intangible assets, software development costs and property and equipment are subsequently measured at fair value when there is an indicator of impairment and recorded at fair value only when impairment is recognized.
Impact of Recently Issued Accounting Standards	Impact of Recently Issued Accounting Standards Pronouncements Recently Adopted In July 2015, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standards Update (“ASU”) No. 2015-11, “Simplifying the Measurement of Inventory” (“ASU 2015-11”), which modifies existing requirements regarding measuring inventory at the lower of cost and market. Under existing standards, the market amount requires consideration of replacement cost, net realizable value (“NRV”), and NRV less an approximately normal profit margin. ASU 2015-11 replaces market with NRV, defined as estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. This eliminates the need to determine and consider replacement cost or NRV less an approximately normal profit margin when measuring inventory. This standard is effective for the Company prospectively beginning January 1, 2017. Adoption of ASU 2015-11 did not have a material impact on the Company’s consolidated financial statements. In November 2015, the FASB issued Accounting Standards Update No. 2015-17, “Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes” (“ASU 2015-17”), which simplifies the presentation of deferred income taxes by requiring deferred tax assets and liabilities be classified as noncurrent on the balance sheet. ASU 2015-17 is effective beginning on January 1, 2017 with early application permitted as of the beginning of any interim or annual reporting period. Adoption of ASU 2015-17 did not have a material impact on the Company’s consolidated financial statements. Pronouncements Not Yet Adopted In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, As Amended (“ASU 2014-09”), which will replace numerous requirements in U.S. GAAP, including industry-specific requirements, provides companies with a single revenue recognition model for recognizing revenue from contracts with customers and significantly expands the disclosure requirements for revenue arrangements. The new standard, as amended, will be effective for the Company for interim and annual reporting periods beginning on January 1, 2018. The two permitted transition methods under the new standard are the full retrospective method, in which case the standard would be applied to each prior reporting period presented, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized at the date of initial application with disclosure of results under the new and old standards for the first year of adoption. The Company will adopt the standard as of January 1, 2018, using the modified retrospective transition method. Under the modified retrospective transition method, the Company will calculate and record the cumulative effect of adopting the new standard at January 1, 2018 for all open contracts, in the Company’s Quarterly Report on Form 10-Q for the first quarter of 2018. Based on its evaluation process, the Company has identified certain potential areas of impact. Application of the new standard requires that incremental costs of obtaining a contract (including sales commissions plus any associated fringe benefits) be recognized as an asset and expensed over the expected life of the arrangement. Currently the Company expenses certain contract acquisition costs as incurred. Under the new standard the Company will defer incremental commission costs to obtain a contract and amortize those costs over the period of benefit. ASU 2014-09 allows, as a policy election, sales commissions related to contracts less than one year to be expensed as incurred instead of capitalized, as a practical expedient. The Company has elected this practical expedient. Therefore, only commissions related to contracts greater than one year will be capitalized. Additionally, the Company has reviewed the way it manages volume tiered discounts and penalties. Currently, revenue adjustments are recorded as discounts or penalties when incurred. Under ASU 2014-09, these items will be treated as variable consideration and good faith estimates will be made up front, which will have the impact of reducing some of the revenue. Variable consideration will be reassessed quarterly. Contract modifications under prior guidance were handled as modifications, if the adjustment was for additional hours on time and materials contracts, which were adjusted and charged as work is performed monthly. Under ASU 2014-09, we will continue to account for large scope changes with significant additional distinct services with related price increases that reflect our stand-alone selling price of the scope change as separate contracts. ASU 2014-09 allows, as a transition practical expedient, for contracts modified prior to the beginning of the earliest reporting period presented under the new standard (January 1, 2018 for the Company), an entity can reflect the aggregate effect of all modifications that occur before the beginning of the earliest period presented under the new standard when identifying the satisfied and unsatisfied performance obligations, determining the transaction price and allocating the transaction price to the satisfied and unsatisfied performance obligations for the modified contract at transition. We are electing this practical expedient. Based on contracts in process at December 31, 2017, the Company expects to record, upon adoption of ASU 2014-09, a net cumulative adjustment to shareholders’ equity not to exceed $1.0 million. The adjustment to retained earnings primarily relates to the modification of the amortization of implementation related deferred revenues and costs. Sales commissions were not a material amount for open contracts at December 31, 2017 and, therefore, will not have an impact at adoption. The Company will make certain presentation changes on its consolidated balance sheet to comply with the new standard. In February 2016, the FASB issued ASU No. 2016-02, “Leases” (“ASU 2016-02”). ASU 2016-02 establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company is currently assessing the impact of ASU 2016-02 on its consolidated financial statements, but does expect the adoption to have a material impact to the balance sheet through the addition of an ROU asset and corresponding lease liability. In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments - a consensus of the Emerging Issues Task Force” (“ASU 2016-15”). ASU 2016-15 is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. Certain issues addressed in this guidance include - debt payments or debt extinguishment costs, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, distributions received from equity method investments and beneficial interests in securitization transactions. ASU 2016-15 is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. ASU 2016-15 is not expected to have a material impact on the Company’s consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business” (“ASU 2017-01”). ASU 2017-01 clarifies the definition of a business when evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses, ASU 2017-01 is effective for annual reporting periods, and interim periods therein, beginning after December 15, 2017, and interim periods within those annual periods. ASU 2017-01 is not expected to have a material impact on the Company’s consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, “Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill impairment” (“ASU 2017-04”), which removes Step 2 of the goodwill impairment test. A goodwill impairment will now be determined by the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. ASU 2017-04 is effective for annual reporting periods, and interim periods therein, beginning after December 15, 2019, with early adoption permitted. The Company is currently evaluating the effect of ASU 2017-04. On May 10, 2017, the FASB issued ASU No. 2017-09, “Compensation–Stock Compensation (Topic 718): Scope of Modification Accounting” (“ASU 2017-09”), clarifying when a change to the terms or conditions of a stock-based payment award must be accounted for as a modification. ASU 2017-09 requires modification accounting if the fair value, vesting condition or the classification of the award is not the same immediately before and after a change to the terms and conditions of the award. ASU 2017-09 is effective for the Company on a prospective basis beginning on January 1, 2018. ASU 2017-09 is not expected to have an impact on the Company’s consolidated financial statements as it is not the Company’s practice to change either the terms or conditions of stock-based payment awards once they are granted.
