Significant Accounting Policies

2. SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

All intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of condensed consolidated financial statements and related disclosures in conformity with U.S. 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 condensed 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 on 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 condensed 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. These uncertainties are discussed in this report and in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 in the section entitled “Risk Factors.” 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 condensed consolidated financial statements are fairly stated in accordance with U.S. 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 that a sales arrangement exists, product shipment or delivery has occurred or services are 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 basis, 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 co-op 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 condensed 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.

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.

Deferred Revenues and Deferred Costs

The Company primarily performs its distribution services and order management customer care 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.

Concentration of Business and Credit Risk

No product customer nor service fee client relationship represented more than 10% of the Company’s consolidated total revenues during the nine months ended September 30, 2017. One service fee client relationship represented 10% of the Company’s consolidated total revenues during the nine months ended September 30, 2016. No client exceeded 10% of consolidated accounts receivable as of September 30, 2017. Amounts due from one client exceeded 10% of consolidated accounts receivable as of December 31, 2016.

A summary of the nonaffiliated customer and client revenue concentrations as a percentage of product revenue and service fee revenue, respectively, is as follows:

	Nine Months Ended
	September 30,
	2017			2016
Service Fee Revenue (as a percentage of total Service Fee Revenue):
Client 1		9	%		10	%
Product Revenue (as a percentage of total Product Revenue):
Customer 1		6	%		13	%
Customer 2		13	%		16	%
Customer 3		12	%		5	%

The Company currently anticipates that its product revenue, including the revenue from certain of the customers identified above, will decline during the next twelve months.

The Company has provided certain collateralized guarantees of its subsidiaries’ financings and credit arrangements. These subsidiaries’ ability to obtain financing on similar terms would be significantly impacted without these guarantees.

The Company has multiple arrangements with International Business Machines Corporation (“IBM”) and Ricoh. These arrangements include Supplies Distributors’ distributor agreements and certain of Supplies Distributors’ working capital financing agreements. The majority of Supplies Distributors’ revenue is generated by its sale of product purchased from Ricoh. Supplies Distributors also relies upon Ricoh’s sales force and product demand generation activities and the discontinuance of such services would have a material impact upon Supplies Distributors’ business. In addition, Supplies Distributors has product sales to IBM and Ricoh business affiliates.

As a result of certain operational restructuring of its business, Ricoh has implemented, and will continue to implement, certain changes in the sale and distribution of Ricoh products. The changes have resulted, and are expected to continue to result, in reduced revenues and profitability for Supplies Distributors.

Operating Leases

The Company leases certain real estate for its warehouse, call center, sales, professional services and corporate offices, as well as certain equipment, under non-cancelable operating leases that expire at various dates through 2026. Management expects that, in the normal course of business, leases that expire will be renewed or replaced by other similar leases. The Company recognizes escalating lease payments on a straight-line basis over the term of each respective lease, and classifies with the difference between cash payments and rent expense recognized as deferred rent in the accompanying condensed consolidated balance sheets.

Property and Equipment

The Company’s property and equipment held under capital leases totaled approximately $3.3 million and $5.4 million, net of accumulated amortization of approximately $7.3 million and $5.1 million, at September 30, 2017 and December 31, 2016, respectively. Depreciation and amortization expense related to capital leases during the nine months ended September 30, 2017 and 2016 was $2.3 million and $2.1 million, respectively.

Income Taxes

The Company records a tax provision primarily associated with state income taxes and the majority of its international operations. The Company has recorded a valuation allowance for the majority of its domestic net deferred tax assets, which are primarily related to net operating loss carryforwards and certain foreign deferred tax assets.

Cash Paid for Interest and Taxes

The Company made payments for interest of approximately $1.9 million and $1.1 million in the nine months ended September 30, 2017 and 2016, respectively. Income taxes of approximately $1.0 million and $0.7 million were paid by the Company in the nine months ended September 30, 2017 and 2016, respectively.

Impact of Recently Issued Accounting Standards

Pronouncements Recently Adopted

In March 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2016-09, “Compensation Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” The amendment in this ASU affects all organizations that issue share-based payment awards to employees and is intended to simplify several aspects of the accounting for these awards, including income tax consequences, classification of awards as either equity or liabilities, classification on the statement of cash flows, and allowing an accounting policy election to account for forfeitures as they occur. As permitted by ASU 2016-09, the Company elected to early adopt ASU 2016-09 in the quarter ended June 30, 2016 with an effective date of January 1, 2016. As a result of the adoption, the Company recognized previously unrecognized excess tax benefits of $1.9 million, which was offset by a valuation allowance in the same amount as the Company does not believe, on a more-likely-than-not basis, the net operating losses will be realized. The adoption of ASU 2016-09 resulted in a cumulative adjustment to equity, subject to a full valuation allowance, as of January 1, 2016. Additionally, as a result of the adoption, the Company reclassified previous years taxes paid on behalf of employees for withheld shares in the condensed consolidated cash flow statements.

In July 2015, the FASB issued ASU No. 2015-11, “Simplifying the Measurement of Inventory,” which modifies existing requirements regarding measuring inventory at the lower of cost or market. Under existing standards, the market amount requires consideration of replacement cost, net realizable value (NRV), and NRV less an approximately normal profit margin. The new ASU 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. The Company adopted this standard prospectively effective January 1, 2017, which did not have a material impact on the Company’s unaudited condensed consolidated financial statements.

In November 2015, the FASB issued ASU No. 2015-17, “Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes,” which simplifies the presentation of deferred income taxes by requiring deferred tax assets and liabilities be classified as noncurrent on the balance sheet. The Company adopted this standard effective January 1, 2017, which did not have a material impact on the unaudited condensed consolidated financial statements.

Pronouncements Not Yet Adopted

In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers.” The new guidance outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry specific guidance. The core principle behind ASU No. 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods and services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for delivering those goods and services. The standard creates a model that requires companies to exercise judgment when considering the terms of a contract and all relevant facts and circumstances. The new standard requires significantly expanded disclosures about revenue contract assets and liabilities and includes new accounting principles related to the deferral and amortization of contract acquisition and fulfillment costs. The ASU allows two methods of adoption: (a) a full retrospective approach in which the standard is applied to all periods presented, or (b) a modified retrospective approach in which the standard is applied only to the most current period presented in the financial statements. In August 2015, the FASB deferred the effective date of this standards update to fiscal years beginning after December 15, 2017, with early adoption permitted on the original effective date of fiscal years beginning after December 15, 2016. The Company currently anticipates adopting the standard on January 1, 2018 using the modified retrospective method. The Company is assessing the new standard and analyzing the standard’s impact on the Company’s internal controls, accounting policies and financial statements and disclosures. As the Company is in the process of evaluating the impact of the standard, it has not yet quantified the impact of the adoption. However, based on the initial phase of 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, unless that life is less than one year. Currently the Company expenses certain of these contract acquisition costs as incurred. Additionally, the Company is assessing the expanded disclosure requirements of the new standard and whether the principal versus agent considerations would change how it presents certain revenues, primarily pass-through revenues. We are in the process of implementing related changes to our financial reporting processes and related internal controls over financial reporting. We do not expect these changes to result in a material impact to those reporting processes or internal controls. The Company expects to continue its evaluation and implementation processes, which will include the quantification of impact and development of policies, to facilitate adoption during the quarter ended March 31, 2018.

In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)," which modifies the accounting for leases, intending to increase transparency and comparability of organizations by requiring balance sheet presentation of leased assets and increased financial statement disclosure of leasing arrangements. ASU 2016-02 will require entities to recognize a liability for their lease obligations and a corresponding asset representing the right to use the underlying asset over the lease term. Lease obligations are to be measured at their present value and accounted for using the effective interest method. The accounting for the leased asset will differ slightly depending on whether the agreement is deemed to be a financing or operating lease. For financing leases, the leased asset is depreciated on a straight-line basis and depreciation expense is recorded separately from the interest expense in the statements of operations, resulting in higher expense in the earlier part of the lease term. For operating leases, the depreciation and interest expense components are combined, recognized evenly over the term of the lease, and presented as a reduction to operating income. ASU 2016-02 requires that assets and liabilities be presented or disclosed separately, and requires additional disclosure of certain qualitative and quantitative information related to these lease agreements. ASU 2016-02 is effective for annual and interim periods beginning after December 15, 2018. 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 ASU’s impact 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 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”). The new guidance 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. The Company is currently assessing this ASU’s impact on its unaudited condensed 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 assessing this ASU’s impact on its unaudited condensed consolidated financial statements.

In May 2017, the Financial Accounting Standards Board (the “FASB”) issued ASU 2017-09, “Compensation Stock Compensation (Topic 718): Scope of Modification Accounting” (“ASU 2017-09”). The amendments in this ASU affect any entity that changes the terms or conditions of a share-based payment award. The new guidance is intended to provide clarity and reduce both (1) diversity in practice and (2) cost and complexity when applying the guidance in Topic 718, Compensation—Stock Compensation, to a change to the terms or conditions of a share-based payment award. ASU 2017-09 is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently assessing this ASU’s impact on its unaudited condensed consolidated financial statements.

Acquisitions

3. ACQUISITIONS

Acquisitions have been recorded using the purchase method of accounting for business combinations.

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 from 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 at June 8, 2016), 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 September 30, 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.

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

The purchase price for Conexus was as follows (in thousands):

Aggregate cash payments

8,515

Performance-based contingent payments (based on

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.

The Company is amortizing the identifiable intangible assets acquired using a pattern in which the economic benefit of the assets are expected to be realized by the Company over their estimated remaining useful lives. There are no residual values for any of the intangible assets subject to amortization acquired during the Conexus acquisition.

Definite lived intangible assets acquired in the Conexus acquisition consist of (in thousands):

													Estimated

Unaudited pro forma historical results of operations related to the Conexus acquisition have not been presented because they are not material to the Company’s condensed consolidated statements of operations.

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 Payment, 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 Payment, 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 Payment in restricted shares of Company common stock, based on its current market value at the time of issuance. As of September 30, 2017, the Company had recorded a liability of $3.9 million applicable to the estimated 2017 CrossView Earn-out Payment, which is included in performance-based contingent payments in the condensed 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 Payment partially offset by an increase in the estimated 2017 CrossView Earn-Out Payment resulting from updated CrossView financial projections for the 2017 earn-out period.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Stock and Stock Options	6. STOCK AND STOCK OPTIONS The Company has an Employee Stock and Incentive Plan, as amended and restated (the “Employee Plan”). The 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 uses newly issued shares of common stock to satisfy awards under the Plan. Total stock-based compensation expense was $0.8 million and $0.3 million for the three months ended September 30, 2017 and 2016, respectively, and $2.5 million and $1.7 million for the nine months ended September 30, 2017 and 2016, respectively, which is included as a component of selling, general and administrative expenses in the unaudited condensed consolidated statements of operations. On March 23, 2015, the Company issued Performance-Based Share Awards (as such terms are defined in the Employee Plan) to the Company’s executives and senior management. Under the terms of these 2015 awards, the number of performance shares that each such individual received was subject to, and calculated by reference to, the achievement by the Company of a performance goal measured by a range of targeted financial performance, as defined, for 2015. Based on the Company’s 2015 financial results, the Company issued an aggregate of approximately 283,100 Performance Shares (“2015 Performance Shares”). The 2015 Performance Shares are subject to four year annual vesting based upon continued employment and the achievement of a defined annual financial target, and for certain of the performance shares, the comparative performance (on an annual and cumulative basis) of the Company’s common stock on NASDAQ compared to the Russell Micro Cap Index. The actual number of shares issued on each annual vesting date could range from zero to 100%, depending on the satisfaction of the vesting criteria. 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. Based upon achievement of the respective vesting criteria, 70,800 of the 2015 Performance Shares vested as of December 31, 2016. As of September 30, 2017, 113,312 of the 2015 Performance Shares did not vest and were forfeited. In March 2016, pursuant to the Employee Plan, the Company issued additional Restricted Stock Units and 2016 Performance Share Awards (as such terms are defined in the Employee Plan) to the Company’s executive officers and certain senior management under which the number of performance shares to be issued was subject to, and calculated by reference to, the achievement by the Company of a performance goal measured by a range of targeted financial performance, as defined, for 2016 as well as, for certain of the Restricted Stock Units, individual performance goals, as defined. Based on the Company’s 2016 financial performance, no performance shares were awarded under the 2016 Restricted Stock Units and 2016 Performance Based Share Awards. On March 31, 2017, the Company issued Restricted Stock Units and Performance-Based Share Awards (as such terms are defined in the Employee Plan) 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, including the achievement by the Company of certain performance goals measured by defined ranges of targeted financial performance for 2017 and/or future years, the achievement of certain defined total stockholder return targets using the companies in the Russell Micro Cap Index as a comparative group for 2017 and/or future years and/or continued employment through one to three year vesting dates. Assuming satisfaction of all vesting conditions and achievement of the highest performance targets, the aggregate maximum number of shares that could be awarded under these 2017 awards is approximately 692,000. 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.

Inventory Financing	7. INVENTORY FINANCING Supplies Distributors has a short-term credit facility with IBM Credit LLC (“IBM Credit”) 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 $6.5 million and $7.3 million as of September 30, 2017 and December 31, 2016, respectively, as accounts payable in the condensed consolidated balance sheets. As of September 30, 2017, Supplies Distributors had $0.1 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 September 30, 2017 and 4.25% as of December 31, 2016). The facility also includes a monthly service fee. As of and for the three and nine months ended September 30, 2017, the Company was in compliance with all financial covenants.

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 including Bank of America N.A. and HSBC Bank USA, National Association (the “Lenders”). 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 September 30, 2017, the Company had $11.3 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 September 30, 2017 and December 31, 2016, the weighted average interest rate on the revolving loan facility was 4.50% and 3.79%, respectively. As of September 30, 2017 and December 31, 2016, the weighted average interest rate on the term loan facility was 3.97% and 2.93%, 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 vendor 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. As of and for three and nine months ended September 30, 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.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	10. COMMITMENTS AND CONTINGENCIES 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. 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 September 30, 2017, the Company believes it has adequately accrued for the expected assessment. The Company is subject to claims in the ordinary course of business, including claims by terminated employees, claims relating to invoice disputes and claims of alleged infringement by the Company or its subsidiaries of the patents, trademarks and other intellectual property rights of third parties. The Company is generally required to indemnify its service fee clients against any third party claims asserted against such clients alleging infringement by the Company 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.

Impact on adoption of accounting standards update			The ASU allows two methods of adoption: (a) a full retrospective approach in which the standard is applied to all periods presented, or (b) a modified retrospective approach in which the standard is applied only to the most current period presented in the financial statements. In August 2015, the FASB deferred the effective date of this standards update to fiscal years beginning after December 15, 2017, with early adoption permitted on the original effective date of fiscal years beginning after December 15, 2016. The Company currently anticipates adopting the standard on January 1, 2018 using the modified retrospective method. The Company is assessing the new standard and analyzing the standard’s impact on the Company’s internal controls, accounting policies and financial statements and disclosures. As the Company is in the process of evaluating the impact of the standard, it has not yet quantified the impact of the adoption. However, based on the initial phase of 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, unless that life is less than one year.
