Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

We are a national solutions provider of a wide range of information technology (“IT”) solutions. We help our customers design, enable, manage, and service their IT environments. We provide IT products, including computer systems, software and peripheral equipment, networking communications, and other products and accessories that we purchase from manufacturers, distributors, and other suppliers. We also offer services involving design, configuration, and implementation of IT solutions. These services are performed by our personnel and by third-party providers. We operate through three sales segments, which serve primarily: (a) small- to medium-sized businesses, in our Business Solutions segment, through our PC Connection Sales subsidiary, (b) large enterprise customers, in our Enterprise Solutions segment, through our MoreDirect and GlobalServe subsidiaries, and (c) federal, state, and local government and educational institutions, in our Public Sector Solutions segment, through our GovConnection subsidiary.

The following is a summary of our significant accounting policies:

Principles of Consolidation

The consolidated financial statements include the accounts of PC Connection, Inc. and its subsidiaries, all of which are wholly-owned. Intercompany transactions and balances are eliminated in consolidation.

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts and disclosures of assets and liabilities and the reported amounts and disclosures of revenue and expenses during the period. By nature, estimates are subject to an inherent degree of uncertainty. Actual results could differ from those estimates and assumptions.

Revenue Recognition

Revenue on product sales is recognized at the point in time when persuasive evidence of an arrangement exists, the price is fixed or determinable, delivery has occurred, and there is a reasonable assurance of collection of the sales proceeds. We generally obtain oral or written purchase authorizations from our customers for a specified amount of product at a specified price. Because we either (i) have a general practice of covering customer losses while products are in-transit despite title transferring at the point of shipment or (ii) have FOB–destination shipping terms specifically set out in our arrangements with federal agencies and certain commercial customers, delivery is deemed to have occurred at the point in time when the product is received by the customer.

We provide our customers with a limited thirty-day right of return generally limited to defective merchandise. Revenue is recognized at delivery and a reserve for sales returns is recorded. We make reasonable and reliable estimates of product returns based on significant historical experience and record our sales reserves as a reduction of revenues and either as offsets to accounts receivable or, for customers who have already paid, as offsets to accrued expenses. At December 31, 2017, we recorded sales reserves of $3,308 and $167 as components of accounts receivable and accrued expenses, respectively. At December 31, 2016, we recorded sales reserves of $3,709 and $220 as components of accounts receivable and accrued expenses, respectively.

All amounts billed to a customer in a sales transaction related to shipping and handling, if any, represent revenues earned for the goods provided, and these amounts have been classified as “net sales.” Costs related to such shipping and handling billings are classified as “cost of sales.” Sales are reported net of sales, use, or other transaction taxes that are collected from customers and remitted to taxing authorities.

We use our own engineering personnel in projects involving the design and installation of systems and networks, and we also engage third-party service providers to perform warranty maintenance, implementations, asset disposals, and other services. Service revenue is recognized over time as the services are performed. We evaluate such engagements to determine whether we or the third party assumes the general risk and reward of ownership in these transactions. For those transactions in which we do not assume the risk and reward but instead act as an agent, we recognize the transaction revenue on a net basis. Under net sales recognition, the cost of the third party is recorded as a reduction to the selling price, resulting in net sales being equal to the gross profit on the transaction. In those engagements in which we are the principal and primary obligor, we report the sale on a gross basis, and the cost of the service provider is recognized in cost of goods sold.

Similarly, we recognize revenue from agency sales transactions on a net sales basis. In agency sales transactions, we facilitate product sales by equipment and software manufacturers directly to our customers and receive agency, or referral, fees for such transactions. We do not take title to the products or assume any maintenance or return obligations in these transactions; title is passed directly from the supplier to our customer.

Amounts recognized on a net basis included in net sales for such third-party services and agency sales transactions were $38,341, $30,234, and $24,158 for the years ended December 31, 2017, 2016, and 2015, respectively.

In certain revenue arrangements, our contracts require that we provide multiple units of hardware, software, or services deliverables. Under these multiple-element arrangements, each service performed and product delivered is considered a separate deliverable and qualifies as a separate unit of accounting. For material multiple element arrangements, we allocate revenue based on vendor-specific objective evidence of fair value of the underlying services and products. If we were to enter into a multiple element arrangement in which vendor-specific objective evidence was not available, we would utilize third-party evidence to allocate the selling price. If neither vendor-specific objective evidence nor third-party evidence was available, we would estimate the selling price based on market price and company specific factors.

Cost of Sales and Certain Other Costs

Cost of sales includes the invoice cost of the product, direct employee and third party cost of services, direct costs of packaging, inbound and outbound freight, and provisions for inventory obsolescence, adjusted for discounts, rebates, and other vendor allowances.

Cash and Cash Equivalents

We consider all highly liquid short-term investments with original maturities of 90 days or less to be cash equivalents. The carrying value of our cash equivalents approximates fair value. The majority of payments due from credit card processors and banks for third-party credit card and debit card transactions process within one to five business days. All credit card and debit card transactions that process in less than seven days are classified as cash and cash equivalents. Amounts due from banks for credit card transactions classified as cash equivalents totaled $6,776 and $4,345 at December 31, 2017 and 2016, respectively.

Accounts Receivable

We perform ongoing credit evaluations of our customers and adjust credit limits based on payment history and customer creditworthiness. We maintain an allowance for estimated doubtful accounts based on our historical experience and the customer credit issues identified. Our customers do not post collateral for open accounts receivable. We monitor collections regularly and adjust the allowance for doubtful accounts as necessary to recognize any changes in credit exposure. Trade receivables are written off in the period in which they are deemed uncollectible. Recoveries of trade receivables previously charged are recorded when received.

Inventories

Inventories (all finished goods) consisting of software packages, computer systems, and peripheral equipment, are stated at cost (determined under a weighted-average cost method which approximates the first-in, first-out method) or net realizable value, whichever is lower. Inventory quantities on hand are reviewed regularly, and allowances are maintained for obsolete, slow moving, and nonsalable inventory.

Vendor Consideration

We receive funding from merchandise vendors for price protections, discounts, product rebates, and other programs. These allowances are treated as a reduction of the vendor’s prices and are recorded as adjustments to cost of sales or inventory, as applicable. Allowances for product rebates that require certain volumes of product sales or purchases are recorded as the related milestones are probable of being met.

Advertising Costs and Vendor Consideration

Costs of producing and distributing catalogs are charged to expense in the period in which the catalogs are first circulated. Other advertising costs are expensed as incurred.

Vendors have the ability to place advertisements in our catalogs or fund other advertising activities for which we receive advertising consideration. This vendor consideration, to the extent that it represents specific reimbursements of incremental and identifiable costs, is offset against SG&A expenses. Advertising consideration that cannot be associated with a specific program or that exceeds the fair value of advertising expense associated with that program is classified as an offset to cost of sales. Our vendor partners generally consolidate their funding of advertising and other marketing programs, and accordingly, we classify substantially all vendor consideration as a reduction of cost of sales rather than a reduction of advertising expense. Advertising expense, which is classified as a component of SG&A expenses, totaled $14,437, $16,083, and $15,689, for the years ended December 31, 2017, 2016, and 2015, respectively.

Property and Equipment

Property and equipment are stated at cost, net of accumulated depreciation and amortization. Depreciation and amortization is provided for financial reporting purposes over the estimated useful lives of the assets ranging from three to seven years. Computer software, including licenses and internally developed software, is capitalized and amortized over lives generally ranging from three to seven years. Depreciation is recorded using the straight-line method. Leasehold improvements and facilities under capital leases are amortized over the terms of the related leases or their useful lives, whichever is shorter, whereas for income tax reporting purposes, they are amortized over the applicable tax lives.

Costs incurred to develop internal-use software during the application development stage are recorded in property and equipment at cost. External direct costs of materials and services consumed in developing or obtaining internal-use computer software and payroll-related costs for employees developing internal-use computer software projects, to the extent of their time spent directly on the project and specific to application development, are capitalized.

When events or circumstances indicate a potential impairment, we evaluate the carrying value of property and equipment based upon current and anticipated undiscounted cash flows. We recognize impairment when it is probable that such estimated future cash flows will be less than the asset carrying value.

Goodwill and Other Intangible Assets

Our intangible assets consist of (1) goodwill, which is not subject to amortization; (2) an internet domain name, which is an indefinite-lived intangible not subject to amortization; and (3) amortizing intangibles, which consist of customer lists, trade names, and customer relationships, which are being amortized over their useful lives.

Note 3 describes the annual impairment methodology that we employ on January 1st of each year in calculating the recoverability of goodwill and non-amortizing intangibles. This same impairment test is performed at other times during the course of a year should an event occur or circumstance change that would more likely than not reduce the fair value of a reporting unit below its carrying amount.

Recoverability of amortizing intangible assets is assessed only when events have occurred that may give rise to impairment. When a potential impairment has been identified, forecasted undiscounted net cash flows of the operations to which the asset relates are compared to the current carrying value of the long-lived assets present in that operation. If such cash flows are less than such carrying amounts, long-lived assets including such intangibles, are written down to their respective fair values.

Concentrations

Concentrations of credit risk with respect to trade account receivables are limited due to the large number of customers comprising our customer base. No single customer accounted for more than 3% of total net sales in 2017, 2016, and 2015. While no single agency of the federal government comprised more than 3% of total sales, aggregate sales to the federal government as a percentage of total net sales were 7.8%, 7.5%, and 6.7% in 2017, 2016, and 2015, respectively.

Product purchases from Ingram Micro, Inc. (“Ingram”), our largest supplier, accounted for approximately 22% of our total product purchases in 2017 and 21% in both 2016 and 2015. Purchases from Synnex Corporation (“Synnex”) comprised 12%, 13%, and 15% of our total product purchases in 2017, 2016, and 2015, respectively. Purchases from HP accounted for approximately 11% of our total product purchases in 2017 and 9% in both 2016 and 2015. Purchases from Tech Data accounted for approximately 11% of our total product purchases in 2017 and 8% in both 2016 and 2015. No other vendor supplied more than 10% of our total product purchases in 2017, 2016, or 2015. We believe that, while we may experience some short-term disruption, alternative sources for products obtained directly from Ingram, Synnex, HP, and Tech Data are available to us.

Products manufactured by HP represented 20% of our net sales in 2017 and 2016, and 22% in 2015. We believe that in the event we experience either a short-term or permanent disruption of supply of HP products, such disruption would likely have a material adverse effect on our results of operations and cash flows.

Earnings Per Share

Basic earnings per common share is computed using the weighted average number of shares outstanding. Diluted earnings per share is computed using the weighted average number of shares outstanding adjusted for the incremental shares attributable to nonvested stock units and stock options outstanding, if dilutive.

The following table sets forth the computation of basic and diluted earnings per share:



	2017		2016		2015
Numerator:
Net income	$	54,857	$	48,111	$	46,827
Denominator:
Denominator for basic earnings per share		26,771		26,528		26,398
Dilutive effect of employee stock awards		120		191		218
Denominator for diluted earnings per share		26,891		26,719		26,616
Earnings per share:
Basic	$	2.05	$	1.81	$	1.77
Diluted	$	2.04	$	1.80	$	1.76

For the years ended December 31, 2017, 2016, and 2015, we did not exclude any outstanding nonvested stock units or stock options from the computation of diluted earnings per share because including them would have had an anti-dilutive effect.

Comprehensive Income

We had no items of comprehensive income, other than our net income for each of the periods presented.

Recently Issued Financial Accounting Standards

On May 28, 2014, the Financial Accounting Standards Board, or the FASB, issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers,” which amends the existing accounting standards for revenue recognition. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Company expects to adopt the new standard using the modified retrospective method that will result in a cumulative effect adjustment as of January 1, 2018. We are in the process of determining the effect that the adoption will have on our consolidated financial statements. Based on our analysis to date, we have reached the following tentative conclusions regarding the new standard and how we expect it to affect our consolidated financial statements and related disclosures:

We believe that since substantially all of our revenue is contractual, substantially all of our revenue falls within the scope of ASU No. 2014-09, as amended.

Our hardware revenue is recognized on a gross basis upon delivery. Upon adoption of the new standard, we expect to recognize revenue at an earlier point in time than we are recognizing under current accounting standards for contracts where shipping terms are FOB shipping point.

Upon adoption of the new standard we expect recognition of certain software products, including SAAS offerings and security software, will be on a net basis. This will result in a decrease in net sales and cost of sales, but no change in gross profit.

We expect that our disclosures in our notes to our consolidated financial statements related to revenue recognition will be significantly expanded under the new standard.

Our analysis and evaluation of the new standard remains to be completed due to the complexity of the new standard, the application of judgment, and the requirement for the use of estimates in applying the new standard, as well as the volume of our client portfolio and the related terms and conditions of our contracts that must be reviewed. We have not completed our final analysis of the quantitative impact of the adoption and the operation of our internal controls related to the adoption of the standard.

In February 2016, the FASB issued ASU 2016-02, Leases. The new standard 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 twelve months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The new standard 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. We are currently assessing the potential impact of the adoption of ASU 2016-02 on our consolidated financial statements.

In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment, which simplifies the accounting for goodwill impairments by eliminating step two from the goodwill impairment test. Instead, if the carrying amount of a reporting unit exceeds its fair value, an impairment loss shall be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. ASU 2017-04 also clarifies the requirements for excluding and allocating foreign currency translation adjustments to reporting units related to an entity's testing of reporting units for goodwill impairment and clarifies that an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. ASU 2017-04 is effective for us beginning January 1, 2020 for both interim and annual reporting periods. We are currently assessing the potential impact of the adoption of ASC 2017-04 on our consolidated financial statements.

In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting. The Company adopted this standard on January 1, 2017. The new standard simplifies several aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. Under this guidance, a company recognizes all excess tax benefits and tax deficiencies as income tax expense or benefit in the income statement. This change eliminates the notion of the additional paid-in capital pool and reduces the complexity in accounting for excess tax benefits and tax deficiencies. The primary impact of our adoption was the recognition of excess tax benefits related to equity compensation in our provision for income taxes rather than paid-in capital, which is a change required to be applied on a prospective basis in accordance with the new guidance. There were no unrecognized excess tax benefits at implementation. Accordingly, we recorded discrete income tax benefits in the consolidated statements of income of $1,054 in the year ended December 31, 2017, for excess tax benefits related to equity compensation. The corresponding cash flows are reflected in cash provided by operating activities instead of financing activities, as was previously required. We adopted the cash flow presentation that requires presentation of excess tax benefits within operating activities on a prospective basis. Additionally, under ASU 2016-09, we have elected to continue to estimate equity award forfeitures expected to occur to determine the amount of compensation cost to be recognized in each period. Additional amendments to the accounting for income taxes and minimum statutory withholding tax requirements had no impact on our results of operations. The presentation requirements for cash flows related to employee taxes paid for withheld shares also had no impact to any of the periods presented in our consolidated statements of cash flows since such cash flows have historically been presented as a financing activity.

In July 2015, the FASB issued ASU 2015-11, Simplifying the Measurement of Inventory, which modifies existing requirements regarding measuring inventory at the lower of cost or market. Under prior standards, the market amount required 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. We adopted the standard in the first quarter of 2017 and applied the provisions prospectively. The adoption of ASU 2015-11 did not have a material impact on our consolidated financial statements.

2. ACQUISITIONS

Softmart Acquisition

On May 27, 2016, we acquired substantially all of the assets of Softmart Inc. (“Softmart”), a global supplier of information technology and software services solutions. The purchase of Softmart is consistent with our strategy to expand our software services capabilities. Under the terms of the asset purchase agreement, we paid $31,899, net of cash acquired, and allocated the total purchase price to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values on the date of acquisition. The excess of the purchase price over the net assets acquired represents potential synergies from Softmart’s customer base and its assembled workforce of sales representatives and software service specialists that we acquired in the transaction. This excess of purchase price over the aggregate fair values was recorded as goodwill. We incurred $357 of transaction costs in 2016 related to the acquisition which we have reported in selling, general and administrative expenses in our consolidated statement of income for the year ended December 31, 2016. The operating results of Softmart have been included in the SMB and Large Accounts segments since the acquisition date. The revenues and income from operations were not material to our consolidated results, and accordingly, we have not presented Softmart’s revenues or operating results on a pro forma basis.

The following table reflects components of the net assets acquired and liabilities assumed at fair value as of the closing date.


	Purchase Price

Acquired liabilities		(16,252)
Net assets acquired		32,517
Less cash acquired		(628)
Purchase price at closing, net of cash acquired	$	31,889

We recorded goodwill of $7,366 and $6,948 in our SMB and Large Account segments, respectively, and the aggregate is expected to be fully deductible for tax purposes.

GlobalServe Acquisition

On October 11, 2016, we acquired the outstanding common shares of GlobalServe, Inc. (“GlobalServe”), which has developed an Internet portal tool that simplifies customers’ global IT procurement. Under the terms of the stock purchase agreement, we paid $11,101, net of cash acquired. The purchase of GlobalServe allows us to service our customers’ global IT needs through this OneSource Internet portal with consistent delivery, reporting, pricing, and logistics. We allocated the total purchase price to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values on the date of acquisition and recorded the excess of purchase price over the aggregate fair values as goodwill. In 2016 we incurred $118 of transaction costs related to the acquisition which we have reported in selling, general and administrative expenses in our consolidated statement of income for the year ended December 31, 2016. We have included the operating results of GlobalServe in the Large Account segment since the acquisition date. The revenues and income from operations were not material to our consolidated results, and accordingly, we have not presented GlobalServe’s revenues or operating results on a pro forma basis.

The following table reflects components of the net assets acquired and liabilities assumed at fair value as of the closing date.

3. GOODWILL AND OTHER INTANGIBLE ASSETS

Goodwill

Goodwill and intangible assets with indefinite lives are subject to an annual impairment test and tested more frequently if events or circumstances occur that would indicate a potential decline in fair value. For goodwill, a two-step quantitative test is performed at a reporting unit level which requires, under the first step, that the fair value of a reporting unit is determined and compared to the reporting unit’s carrying value, including goodwill. To assess the fair value of a reporting unit, both income and market valuation approaches are used. If the fair value is determined to be less than the carrying value, the second step is performed to measure the amount, if any, of the impairment.

Our annual impairment test of an indefinite-lived domain name and goodwill is set as of the first day of the year. Goodwill is held by our Large Account and SMB reporting units. The fair value of the domain name and the two reporting units each substantially exceeded the respective carrying value, and accordingly, an impairment was not identified in the annual test. We also did not identify any events or circumstances that would indicate that it is more likely than not that the carrying values of the reporting units or the domain name were in excess of the respective fair values during the year ended December 31, 2017.

To determine the fair value of our reporting units, we considered operating results and future projections, as well as changes in the Company’s overall market capitalization. The significant assumptions used in our discounted cash flow analysis include: projected cash flows and profitability, the discount rate used to present value future cash flows, working capital requirements, and terminal growth rates. Cash flows and profitability assumptions include sales growth, gross margin, and SG&A growth assumptions which are generally based on historical trends. The discount rate used is a "market participant" weighted average cost of capital ("WACC"). For our computation of fair value as of January 1, 2017, we used a WACC rate of 10.7%, and estimated terminal growth rate at 3.0% and working capital requirements at 7.7% of revenues. The carrying amount of goodwill for the periods presented is detailed below:


Balance at December 31, 2016	SMB		Large Account		Public Sector		Total
Goodwill, gross	$	8,539	$	66,236	$	7,634	$	82,409

Intangible Assets

At December 31, 2017, our intangible assets included a domain name for $450, which has an indefinite life and is not subject to amortization. In addition, we acquired in 2016 customer relationships from our Softmart and GlobalServe acquisitions, which will be amortized on a straight-line basis over their estimated useful lives of 10 years. Our remaining intangible assets are amortized in proportion to the estimates of the future cash flows underlying the valuation of the assets. Intangible assets and related accumulated amortization are detailed below:


		December 31, 2017						December 31, 2016
	Estimated	Gross		Accumulated		Net		Gross		Accumulated		Net
	Useful Lives	Amount		Amortization		Amount		Amount		Amortization		Amount

Preferred Stock

Our Amended and Restated Certificate of Incorporation (the “Restated Certificate”) authorizes the issuance of up to 10,000 shares of preferred stock, $.01 par value per share (the “Preferred Stock”). Under the terms of the Restated Certificate, the Board is authorized, subject to any limitations prescribed by law, without stockholder approval, to issue by a unanimous vote such shares of Preferred Stock in one or more series. Each such series of Preferred Stock shall have such rights, preferences, privileges, and restrictions, including voting rights, dividend rights, redemption privileges, and liquidation preferences, as shall be determined by the Board. There were no preferred shares outstanding at December 31, 2017 or 2016.

Share Repurchase Authorization

In 2001, our Board of Directors authorized the spending of up to $15,000 to repurchase our common stock. We have considered block repurchases directly from larger stockholders, as well as open market purchases, in carrying out our ongoing stock repurchase program.

We did not repurchase any shares in the three years ended December 31, 2017. As of December 31, 2017, we have repurchased an aggregate of 1,682 shares for $12,233 under our repurchase program, and the maximum approximate dollar value of shares that may yet be purchased under this program is $2,767. In 2014, our Board of Directors approved a new share repurchase program authorizing up to $15,000 in share repurchases. There is no fixed termination date for this new repurchase program. Purchases may be made in open-market transactions, block transactions on or off an exchange, or in privately negotiated transactions. We intend to complete the 2001 repurchase program before repurchasing shares under the new program. The timing and amount of any share repurchases will be based on market conditions and other factors.

Dividend Payments

The following table summarizes our special cash dividends declared in the three years ended December 31, 2017:


	2017		2016		2015
Dividend per share	$	0.34	$	0.34	$	0.40

Payment date		1/12/2018		1/12/2017		1/12/2016

The dividends paid in January 2017 and 2018 were included in accrued expenses and other liabilities at December 31, 2016 and 2017, respectively. We have no current plans to pay additional cash dividends on our common stock in the foreseeable future, and declaration of any future cash dividends will depend upon our financial position, strategic plans, and general business conditions.

Equity Compensation Plan Descriptions

In 2007, the Board adopted and our stockholders approved the 2007 Stock Incentive Plan. In 2010, the Board adopted and our stockholders approved the Amended and Restated 2007 Stock Incentive Plan (the “2007 Plan”), which among other things, extended the term of the 2007 Plan to 2020. In May 2016, our stockholders approved an amendment to the 2007 Plan, which authorized the issuance of 1,700 shares of common stock. Under the terms of the 2007 Plan, we are authorized for a ten-year period to grant options, stock appreciation rights, nonvested stock, nonvested stock units, and other stock-based awards to employees, officers, directors, and consultants. As of December 31, 2017, there were 198 shares eligible for future grants under the 2007 Plan.

1997 Employee Stock Purchase Plan

In November 1997, the Board adopted and our stockholders approved the 1997 Employee Stock Purchase Plan (the “Purchase Plan”). The Purchase Plan authorizes the issuance of common stock to participating employees. Under the Purchase Plan, as amended, our employees are eligible to purchase company stock at 95% of the purchase price as of the last business day of each six-month offering period. An aggregate of 1,138 shares of common stock has been reserved for issuance under the Purchase Plan, of which 1,114 shares have been purchased.

Accounting for Share-Based Compensation

We measure the grant date fair value of equity awards given to employees and recognize that cost, adjusted for forfeitures, over the period that services are performed. We value grants with multiple vesting periods as a single award, estimate expected forfeitures based upon historical patterns of employee turnover, and record share-based compensation as a component of SG&A expenses. In 2016, we granted nonvested stock units. No equity awards were granted in 2015 and 2017, however, in previous years both nonvested stock awards and stock options have been granted.

We employ the Black-Scholes option valuation model to assess the grant date fair value of each option grant. The application of this model requires certain key input assumptions, including expected volatility, option term, and risk-free interest rates. Expected volatility is based on the historical volatility of our common stock. The expected term of an option grant is estimated using the historical exercise behavior of employees and directors. The risk‑free interest rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve that corresponds most closely to the stock option’s expected average life.

The following table summarizes the components of share-based compensation recorded as expense for the three years ended December 31, 2017:


	2017		2016		2015
Pre-tax expense for nonvested units	$	741	$	1,049	$	994
Tax benefit		(297)		(420)		(398)
Net effect on net income	$	444	$	629	$	596

We have historically settled stock option exercises with newly issued common shares. The intrinsic value of options exercised in 2017, 2016, and 2015 was $2,569, $156, and $553, respectively. The following table sets forth our stock option activity in 2017:


				Weighted

Vested and expected to vest	—	$	—	—	$	—

In 2016, we issued nonvested stock units that settle in stock and vest over periods up to fifteen years. No awards were issued in 2015 and 2017. Recipients of nonvested stock units do not possess stockholder rights. The fair value of nonvested stock units is based on the end of day market value of our common stock on the grant date. The following table summarizes our nonvested stock unit activity in 2017:


	Nonvested Stock Units
		Weighted-Average
		Grant Date
	Shares	Fair Value
Nonvested at January 1, 2017	354	$	19.34
Vested	(62)		11.41
Canceled	(4)		23.73
Nonvested at December 31, 2017	288		21.01

The weighted-average grant-date fair value of nonvested stock units granted in 2016 was $24.72. No awards were granted in 2015 and 2017. The total fair value of nonvested stock units that vested in 2017, 2016, and 2015 was $1,638, $2,348, and $2,287, respectively. Unearned compensation cost related to the nonvested portion of outstanding nonvested stock units was $5,283 as of December 31, 2017, and is expected to be recognized over a weighted-average period of approximately 7.1 years.

Stock Equivalent Units

We have also issued stock equivalent units, (“SEUs”), which settle in cash and vest ratably over four years, to non-executive employees. The fair value of these liability awards is based on the closing market price of our common stock, and is remeasured at the end of each reporting period until the SEUs vest. We report the compensation as a component of SG&A expense and the related liability as accrued payroll on the consolidated balance sheets.

We have state net operating loss carryforwards aggregating $1,110 at December 31, 2017 representing state tax benefits, net of federal taxes, of approximately $877. These loss carryforwards are subject to between five, fifteen, and twenty-year carryforward periods, with $9 expiring after 2018, $6 expiring after 2019, $5 expiring after 2020, $3 expiring after 2021, $3 expiring after 2022 and $1,084 expiring beyond 2022. We have provided valuation allowances of $745 and $485 at December 31, 2017 and 2016, respectively, against the state tax loss carryforwards, representing the portion of carryforward losses that we believe are not likely to be realized. The net change in the total valuation allowance reflects a $260, $102, and $70 increase in 2017, 2016, and 2015, respectively. The valuation allowance was increased in 2017, 2016, and 2015 to offset the corresponding increase to the deferred tax asset associated with state net operating loss carryforwards.

A reconciliation of our 2017, 2016, and 2015 income tax provision to total income taxes at the statutory federal tax rate is as follows:

On December 22, 2017, the U.S. government enacted comprehensive tax legislation (the “Tax Act”), which significantly revises the ongoing U.S. corporate income tax law by lowering the U.S. federal corporate income tax rate from 35.0% to 21.0%, and setting limitations on deductibility of certain costs.

Due to the complexities involved in accounting for the recently enacted Tax Act, the U.S. Securities and Exchange Commission’s Staff Accounting Bulletin (“SAB”) 118 requires that we include in our financial statements the reasonable estimate of the impact of the Tax Act on earnings to the extent such reasonable estimate has been determined. Accordingly, we recorded a preliminary $7.8 million in estimated tax benefit related to the change in net deferred tax liabilities stemming from the Tax Act’s reduction of the U.S. federal tax rate from 35.0% to 21.0% for the year ended December 31, 2017.

The final impact on our financial statements from the Tax Act may differ due to changes in interpretations of the Tax Act, future legislative action to address questions that arise because of the Tax Act, and related interpretations in response to the Tax Act.

We file one consolidated U.S. Federal income tax return that includes all of our subsidiaries as well as several consolidated, combined, and separate company returns in many U.S. state tax jurisdictions. The tax years 2013-2016 remain open to examination by the major state taxing jurisdictions in which we file. The tax years 2014-2016 remain open to examination by the Internal Revenue Service.

A reconciliation of unrecognized tax benefits for 2017, 2016, and 2015, is as follows:


	2017		2016		2015
Balance at January 1,	$	684	$	869	$	892

Settlements		(157)		—		—
Balance at December 31,	$	368	$	684	$	869

We recognize interest and penalties related to unrecognized income tax benefits as a component of income tax expense, and the corresponding accrual is included as a component of our liability for unrecognized income tax benefits. During the years ended December 31, 2017, 2016, and 2015, we recognized interest and penalties totaling $0, $62, and $110, respectively. At December 31, 2017 and 2016, accrued interest aggregated $481 and $693, respectively, and accrued penalties aggregated $93 and $171, respectively. As of December 31, 2017 and 2016, all unrecognized tax benefits and the related interest and penalties, if recognized, would favorably affect our effective tax rate.

We do not anticipate that total unrecognized tax benefits will change significantly due to the settlement of audits, expiration of statutes of limitations, or other reasons in the next twelve months.

Segment and Related Disclosures

12. SEGMENT AND RELATED DISCLOSURES

The internal reporting structure used by our chief operating decision maker (“CODM”) to assess performance and allocate resources determines the basis for our reportable operating segments. Our CODM is our Chief Executive Officer, and he evaluates operations and allocates resources based on a measure of operating income.

Our operations are organized under three reporting segments—the SMB segment, which serves primarily small- and medium-sized businesses; the Large Account segment, which serves primarily medium-to-large corporations; and the Public Sector segment, which serves primarily federal, state, and local government and educational institutions. In addition, the Headquarters/Other group provides services in areas such as finance, human resources, information technology, marketing, and product management. Most of the operating costs associated with the Headquarters/Other group functions are charged to the operating segments based on their estimated usage of the underlying functions. We report these charges to the operating segments as “Allocations.” Certain headquarters costs relating to executive oversight and other fiduciary functions that are not allocated to the operating segments are included under the heading of Headquarters/Other in the tables below.

In May 2016, we acquired Softmart. We have included the operating results for Softmart in our SMB and Large Account segments from May 27, 2016, the closing date of the acquisition. The external sales and operating results of Softmart since the date of acquisition were immaterial to our consolidated results.

In October 2016, we acquired GlobalServe. We have included the operating results for GlobalServe in our Large Account segment from October 11, 2016, the closing date of the acquisition. The external sales and operating results of GlobalServe were immaterial to our consolidated results.

Net sales presented below exclude inter-segment product revenues. Segment information applicable to our reportable operating segments for the years ended December 31, 2017, 2016, and 2015 is shown below:

The assets of our operating segments presented above consist primarily of accounts receivable, net intercompany receivable, goodwill, and other intangibles. Goodwill of $66,236 and $7,366 is held by our Large Account and SMB segments, respectively, as of December 31, 2017. Assets reported under the Headquarters/Other group are managed by corporate headquarters, including cash, inventory, property and equipment and intercompany balance, net. Total assets for the Headquarters/Other group are presented net of intercompany balances eliminations of $29,731 and $49,937 for the years ended December 31, 2017 and 2016, respectively. Our capital expenditures consist largely of IT hardware and software purchased to maintain or upgrade our management information systems. These systems serve all of our subsidiaries, to varying degrees, and as a result, our CODM does not evaluate capital expenditures on a segment basis.

Substantially, all of our sales in 2017, 2016, and 2015 were made to customers located in the United States. Shipments to customers located in foreign countries were not more than 1% of total net sales in 2017, 2016, and 2015. All of our assets at December 31, 2017 and 2016 were located in the United States. Our primary target customers are SMBs, federal, state, and local government agencies, educational institutions, and medium-to-large corporate accounts. No single customer accounted for more than 3% of total net sales in 2017, 2016, or 2015. While no single agency of the federal government comprised more than 3% of total sales, aggregate sales to the federal government were 7.8%, 7.5%, and 6.7% in 2017, 2016, and 2015, respectively.

Recently Issued Financial Accounting Standards

We believe that since substantially all of our revenue is contractual, substantially all of our revenue falls within the scope of ASU No. 2014-09, as amended.

We expect that our disclosures in our notes to our consolidated financial statements related to revenue recognition will be significantly expanded under the new standard.

Bank Borrowings
Bank Borrowings	6. BANK BORROWINGS We have a $50,000 credit facility collateralized by our account receivables that expires February 10, 2022. This facility can be increased, at our option, to $80,000 for approved acquisitions or other uses authorized by the lender on substantially the same terms. Amounts outstanding under this facility bear interest at the one-month London Interbank Offered Rate (“LIBOR”), plus a spread based on our funded debt ratio, or in the absence of LIBOR, the prime rate (4.50% at December 31, 2017). The one-month LIBOR rate at December 31, 2017 was 1.56%. The credit facility includes various customary financial ratios and operating covenants, including minimum net worth and maximum funded debt ratio requirements, and default acceleration provisions. The credit facility does not include restrictions on future dividend payments. Funded debt ratio is the ratio of average outstanding advances under the credit facility to Adjusted EBITDA (Earnings Before Interest Expense, Taxes, Depreciation, Amortization, and Special Charges). The maximum allowable funded debt ratio under the agreement is 2.0 to 1.0. Decreases in our consolidated Adjusted EBITDA could limit our potential borrowing capacity under the credit facility. We had no outstanding bank borrowings at December 31, 2017 or 2016, respectively, and accordingly, the entire $50,000 facility was available for borrowings under the credit facility.
