Note 1: Business and Basis of Presentation

Business

Black Box Corporation ("Black Box," or "the Company") is a leading digital solutions provider dedicated to helping customers design, build, manage, and secure their IT infrastructure. The Company offers Services and Products that it distributes through two platforms it has built over its 41-year history. The Services platform is comprised of engineering and design, network operations centers, technical certifications, national and international sales teams, remote monitoring, on-site service teams and technology partner centers of excellence which includes dedicated sales and engineering resources. The primary services offered through this platform include: (i) communications lifecycle services, (ii) unified communications, (iii) structured cabling, (iv) video/AV services (v) in-building wireless and (vi) data center services. The Products platform provides networking solutions through the sale of products including: (i) IT infrastructure, (ii) specialty networking, (iii) multimedia and (iv) keyboard/video/mouse ("KVM")switching. Founded in 1976, Black Box, a Delaware corporation, is headquartered near Pittsburgh in Lawrence, Pennsylvania.

Basis of Presentation

The accompanying unaudited interim consolidated financial statements of Black Box have been prepared in accordance with accounting principles generally accepted in the United States ("GAAP") and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. The Company believes that these consolidated financial statements reflect all normal, recurring adjustments needed to present fairly the Company's results for the interim periods presented. The results as of and for interim periods presented may not be indicative of the results of operations for any other interim period or for the full year. These financial statements should be read in conjunction with the financial statements and notes thereto included in the Company's most recent Annual Report on Form 10-K as filed with the Securities and Exchange Commission ("SEC") for the fiscal year ended March 31, 2017 (the "Form 10-K").

The Company's fiscal year ends on March 31. The fiscal quarters consist of 13  weeks and end on the Saturday generally nearest each calendar quarter end, adjusted to provide relatively equivalent business days for each fiscal quarter. The actual ending dates for the periods presented in these Notes to the Consolidated Financial Statements as of June 30, 2017 and 2016 were July 1, 2017 and July 2, 2016 , respectively. References herein to "Fiscal Year" or "Fiscal" mean the Company's fiscal year ended March 31 for the year referenced. All references to dollar amounts herein are presented in thousands, except per share amounts, unless otherwise noted.

The consolidated financial statements include the accounts of the parent company and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. Certain items in the consolidated financial statements of prior years have been reclassified to conform to the current year's presentation. These reclassifications had no effect on reported net income (loss), comprehensive income (loss), cash flows, total assets or total stockholders' equity.

The preparation of financial statements in conformity with GAAP requires Company management ("Management") to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates in these financial statements include project progress towards completion to estimated budget, allowances for doubtful accounts receivable, sales returns, net realizable value of inventories, loss contingencies, warranty reserves, property, plant and equipment, intangible assets and goodwill. Actual results could differ from those estimates. Management believes the estimates made are reasonable.

Note 2: Significant Accounting Policies

Significant Accounting Policies

The significant accounting policies used in the preparation of the Company's consolidated financial statements are disclosed in Note 2 of the Notes to the Consolidated Financial Statements within the Form 10-K. No additional significant accounting policies have been adopted during Fiscal 2018 .

Recent Accounting Pronouncements

In March 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-09, Stock Compensation. This update simplifies several aspects of the accounting for share-based payment transactions and was adopted by the Company during the first quarter of Fiscal 2018. The adoption of this new guidance did not have a material impact on the Company's consolidated financial statements.

Other than above, there have been no other accounting pronouncements adopted during Fiscal 2018.

Note 3: Inventories

The Company's Inventories consist of the following:

Note 4: Intangible Assets

The following table summarizes the gross carrying amount, accumulated amortization and net carrying amount by intangible asset class:

The Company's indefinite-lived intangible assets consist solely of the Company's trademark portfolio. During the first quarter of Fiscal 2018, the Company lowered its projections of revenue and profitability outlook for the foreseeable future. During the second quarter of Fiscal 2018, the Company will conduct an interim assessment of both our definite-lived and indefinite lived intangible assets and determine whether such assets were recoverable as of July 1, 2017. If such assets are not recoverable, the Company could incur a non-cash impairment charge, which could have a material adverse effect on our consolidated balance sheet and results of operations. The Company's definite-lived intangible assets consist solely of customer relationships.

The following table summarizes the changes to the net carrying amounts by intangible asset class:

The following table details the estimated intangibles amortization expense for the remainder of Fiscal 2018 , each of the succeeding four fiscal years and the periods thereafter.

Note 5: Indebtedness

The Company's Long-term debt consists of the following:

(1) Refer below for additional details regarding the Company's amended credit agreement which includes a revolving credit agreement and a term loan.

(2) The Company finances certain vendor-specific inventory under an unsecured revolving arrangement through a third party which provides extended payment terms beyond those offered by the vendor at no incremental cost to the Company. The outstanding balance is recorded as a current liability in Other liabilities within the Company's Consolidated Balance Sheets.

(3) The Company's current portion of total debt consists primarily of the unsecured revolving arrangement disclosed above and minimum repayments of the term loan that are due in the next 12 months, which are $3,750 as of June 30, 2017 .

On May 9, 2016, the Company refinanced its then existing $200,000 credit facility in the form of a line of credit pursuant to a new credit agreement (the "Credit Agreement") with PNC Bank, National Association, as administrative agent, Bank of America, N.A., as syndication agent, and certain other lender parties (the "Banks"). The Credit Agreement expires on May 9, 2021. Borrowings under the Credit Agreement were permitted up to a maximum amount of $200,000 , and included up to $15,000 of swing-line loans and $25,000 of letters of credit. Interest on outstanding indebtedness under the Credit Agreement accrued, at the Company's option, at a rate based on either: (a) a Base Rate Option equal to the highest of (i) the federal funds open rate, plus fifty (50) basis points ( 0.5% ), (ii) the bank's prime rate, and (iii) the daily LIBOR rate, plus 100 basis points ( 1.0% ), in each case plus 0% to 1.00% (determined by a leverage ratio based on the Company's consolidated EBITDA) or (b) a rate per annum equal to the LIBOR rate plus 1.00% to 2.00% (determined by a leverage ratio based on the Company's consolidated EBITDA). The Credit Agreement required the Company to maintain compliance with certain non-financial and financial covenants such as leverage and interest coverage ratios.

The Company's obligations under the Credit Agreement were secured by substantially all of the assets of the Company's material direct and indirect subsidiaries that are incorporated (or organized) under the laws of the District of Columbia or under the laws of any state or commonwealth of the United States and are guaranteed by such domestic subsidiaries.

On August 9, 2017, the Company and certain of the Banks entered into an Amendment and Joinder Agreement to amend and restate the Credit Agreement (as amended and restated, the "Amended Credit Agreement") in order to avoid a default of its leverage covenant. Under the Amended Credit Agreement, the credit facility has been reduced to $170,000 comprised of a $50,000 term loan and $120,000 line of credit. As of August 9, 2017, $50,000 was borrowed under the term loan and $52,528 remained outstanding under the line of credit. The amortization of the term loan is $1,250 per quarter for four (4) quarters beginning in the quarter ending December 31, 2017 and $2,500 per quarter beginning in the quarter ending December 31, 2018 through the end of the Amended Credit Agreement on May 9, 2021, the same expiration date of the Credit Agreement. Mandatory prepayments of the term loan are required with the net proceeds from certain asset sales, insurance recoveries and debt or equity issuances, as well as from 75% to 50% of any excess cash flow generated in Fiscal 2019 and Fiscal 2020. Interest on the term loan is, at the Company's option: (i) a Base Rate Option equal to the highest of (i) the federal funds open rate, plus fifty (50) basis points ( 0.5% ), (ii) the bank's prime rate, and (iii) the daily LIBOR rate, plus 100 basis points ( 1.0% ), in each case plus 2.5% or (ii) LIBOR plus 3.5% . Interest on outstanding indebtedness under the line of credit accrues, at the Company's option, at a rate based on either: (a) the Base Rate Option plus 0.25% to 2.00% (determined by a leverage ratio based on the Company's consolidated EBITDA) or (b) a rate per annum equal to the LIBOR rate plus 1.25% to 3.00% (determined by a leverage ratio based on the Company's consolidated EBITDA).

Under the Amended Credit Agreement, the leverage ratio covenant is suspended until the second quarter of Fiscal 2019. The Amended Credit Agreement contains a minimum Adjusted EBITDA covenant and a provision requiring the Company to repay revolving credit loans with any excess cash. During that same period, a covenant will limit capital expenditures to an agreed upon amount. The ability of the Company to make dividends or other distributions (including stock repurchases other than up to a limited dollar amount for tax payments from vested equity awards) has been eliminated.

The leverage ratio covenant that starts in the second quarter of Fiscal 2019 will be 4.00 to 1.00 and will reduce to 3.00 to 1.00 over the remaining life of the credit facility. A fixed charge coverage ratio of 1.00 to 1.00 begins in the second quarter of Fiscal 2019 increasing to 1.10 to 1.00 in the fourth quarter of Fiscal 2019 and thereafter.

The Company's obligations under the Amended Credit Agreement are secured by substantially all of the assets of the Company and the Company's direct and indirect subsidiaries that are incorporated (or organized) under the laws of the District of Columbia or under the laws of any state or commonwealth of the United States (a "U.S. Entity") and are guaranteed by such domestic subsidiaries. Under the Amended Credit Agreement, the Company and each U.S. Entity pledged 65% of the voting ownership interests and 100% of the non-voting ownership interests of its foreign subsidiaries.

The cost of the Amended Credit Agreement will be approximately $800 , substantially all of which will be amortized over the remaining term of the Amended Credit Agreement. In 2Q18, we expect to recognize expense of $209 related to the write-off of deferred amortization costs of our Credit Agreement due to the reduction in size of the facility in Amended Credit Agreement.

Our Amended Credit Agreement contains covenants requiring us to achieve a certain minimum adjusted EBITDA during each quarter through the first quarter of Fiscal 2019. A leverage ratio and a fixed charge coverage ratio commence in the second quarter of Fiscal 2019 through maturity in May 2021. The covenants in our Amended Credit Agreement were determined based upon our current expectation of revenues and profitability. If we fail to achieve our expected revenues and profitability, we could fail to maintain compliance with the covenants in our Amended Credit Agreement. There can be no assurance that we will be able to remain in compliance with these or other covenants in our Amended Credit Agreement.

The maximum amount of debt outstanding under the Credit Agreement, the weighted-average balance outstanding under the Credit Agreement and the weighted-average interest rate on all outstanding debt for the three-months ended June 30, 2017 was $171,237 , $140,455 and 2.8% , respectively, compared to $150,075 , $133,299 and 2.5% , respectively, for the three-months ended June 30, 2016 .

As of June 30, 2017 , the Company had $4,850 outstanding in letters of credit and $62,622 in unused commitments, which are limited by a financial covenant, under the Amended Credit Agreement.

Note 6: Derivative Instruments and Hedging Activities

The Company is exposed to certain market risks, including the effect of changes in foreign currency exchange rates and interest rates. The Company uses derivative instruments to manage financial exposures that occur in the normal course of business. It does not hold or issue derivatives for speculative trading purposes. The Company is exposed to non-performance risk from the counterparties in its derivative instruments. This risk would be limited to any unrealized gains on current positions. To help mitigate this risk, the Company transacts only with counterparties that are rated as investment grade or higher and all counterparties are monitored on a continuous basis. The fair value of the Company's derivatives reflects this credit risk.

The Company enters into foreign currency contracts to hedge exposure to variability in expected fluctuations in foreign currencies. All of the foreign currency contracts have been designated and qualify as cash flow hedges. The effective portion of any changes in the fair value of the derivative instruments is recorded in Accumulated Other Comprehensive Income ("AOCI") until the hedged forecasted transaction occurs or the recognized currency transaction affects earnings. Once the forecasted transaction occurs or the recognized currency transaction affects earnings, the effective portion of any related gains or losses on the cash flow hedge is reclassified from AOCI to the Company's Consolidated Statements of Operations.

As of June 30, 2017 , the Company had open contracts in Australian and Canadian dollars, Danish krone, Euros, Mexican pesos, Norwegian kroner, British pounds sterling, Swedish krona, Swiss francs and Japanese yen, all of which have been designated as cash flow hedges. These contracts had a notional amount of $49,069 and will expire within 4 months. There was no hedge ineffectiveness during Fiscal 2018 or Fiscal 2017 .

The following tables summarize the carrying amounts of derivative assets/liabilities and the impact on the Company's Consolidated Statements of Operations:

Note 7: Fair Value Disclosures

Recurring fair value measurements

The following table presents information about the Company's assets and liabilities measured at fair value on a recurring basis as of June 30, 2017 , and indicates the fair value hierarchy of the valuation techniques utilized by the Company to determine such fair value:

(1) The fair value of pension plan assets is measured annually, thus this value is as of March 31, 2017 .

Non-recurring fair value measurements

The Company's assets and liabilities that are measured at fair value on a non-recurring basis include non-financial assets and liabilities initially measured at fair value in a business combination.

Note 8: Stockholder's Equity

Accumulated Other Comprehensive Income

The components of AOCI consisted of the following for the periods presented:

Dividends

The following table presents information about the Company's dividend program:

While the Company has paid dividends for the past 49 quarters, it is no longer permitted to do so under the Amended Credit Agreement. The Company expects to use the funds that were previously available for dividends to supplement spending for our previously announced US-based ERP project and to develop and implement growth initiatives for the Company, both of which we believe will create long-term shareholder value. This restriction is in effect until May 9, 2021. See Note 5 for additional information regarding our Amended Credit Agreement.

Common Stock Repurchases

The following table presents information about the Company's common stock repurchases:

During the three -month period ended June 30, 2017 , the Company made tax payments of $393 and withheld 44,507 shares of common stock, which were designated as treasury shares, at an average price per share of $8.84 , in order to satisfy employee income taxes due as a result of the vesting of certain restricted stock units.

Since the inception of its repurchase programs beginning in April 1999 and through June 30, 2017 , the Company has repurchased 11,392,851 shares of common stock for an aggregate purchase price of $408,621 , or an average purchase price per share of $35.87 . These shares do not include the treasury shares withheld for tax payments due upon the vesting of certain restricted stock units and performance shares. As of June 30, 2017 , 1,107,149 shares were available under the most recent repurchase programs.

Under the Amended Credit Agreement, the Company is no longer permitted to repurchase common stock through its repurchase program but is allowed to repurchase a limited amount of shares for tax payments related to the vesting certain restricted stock units and performance shares, as applicable. This restriction is in effect until May 9, 2021. The Company expects to use the funds that were previously available for stock repurchases to supplement spending for our previously announced US-based ERP project and to develop and implement growth initiatives for the Company, both of which we believe will create long-term shareholder value. See Note 5 for additional information regarding our Amended Credit Agreement.

Note 9: Income Taxes

The Company's benefit from income taxes for the three-months ended June 30, 2017 was $4,498 , an effective tax rate of 31.6% on a loss before provision for income taxes of $14,245 , compared to a provision for income taxes of $2,332 , an effective tax rate of 125.6% on income before provision for income taxes of $1,856 for the three-months ended June 30, 2016 . The effective tax rate decrease from 125.6% to 31.6% was primarily due to the mix of income across various taxing jurisdictions. The effective tax rate for the three -months ended June 30, 2017 of 31.6% differs from the federal statutory rate primarily due to the reduction of deferred tax assets associated with equity awards and the mix of income across various taxing jurisdictions.

The Company provides for income taxes at the end of each interim period based on the estimated effective tax rate adjusted for certain discrete items for the full fiscal year. Cumulative adjustments to the Company's estimate are recorded in the interim period in which a change in the estimated annual effective rate is determined.

Fiscal 2013 through Fiscal 2017 remain open to examination by the Internal Revenue Service ("IRS") and Fiscal 2011 through Fiscal 2017 remain open to examination by certain state and foreign taxing jurisdictions.

Note 10: Stock-based Compensation

In August 2008, the Company's stockholders approved the 2008 Long-Term Incentive Plan, as amended (the "Incentive Plan"), which replaced the 1992 Stock Option Plan, as amended, and the 1992 Director Stock Option Plan, as amended. As of June 30, 2017 , the Incentive Plan is authorized to issue stock options, restricted stock units and performance shares, among other types of awards, for up to 5,855,631 shares of common stock, par value $0.001 per share (the "common stock").

The Company recognized stock-based compensation expense of $2,198 and $2,233 for the three-months ended June 30, 2017 and 2016 , respectively. The Company recognized total income tax benefit for stock-based compensation arrangements of $818 and $831 for the three-months ended June 30, 2017 and 2016 , respectively. Stock-based compensation expense is recorded in Selling, general & administrative expenses within the Company's Consolidated Statements of Operations.

Stock options

Stock option awards are granted with an exercise price equal to the closing market price of the common stock on the date of grant; such stock options generally become exercisable in equal amounts over a three -year period and have a contractual life of ten years from the grant date. The fair value of stock options is estimated on the grant date using the Black-Scholes option pricing model, which includes the following weighted-average assumptions.

The following table summarizes the Company's stock option activity:

The weighted-average grant-date fair value of options granted during the three -months ended June 30, 2017 and 2016 was $2.51 and $3.74 , respectively. The intrinsic value of options exercised during the three -months ended June 30, 2017 and 2016 was $0 and $0 , respectively. The aggregate intrinsic value in the preceding table is based on the closing stock price of the common stock on June 30, 2017 , which was $8.55 .

The following table summarizes certain information regarding the Company's non-vested stock options:

As of June 30, 2017 , there was $2,209 of total unrecognized pre-tax stock-based compensation expense related to non-vested stock options, which is expected to be recognized over a weighted-average period of 2.5  years.

Restricted stock units

Restricted stock unit awards are subject to a service condition and typically vest in equal amounts over a three -year period from the grant date. The fair value of restricted stock units is determined based on the number of restricted stock units granted and the closing market price of the common stock on the date of grant.

The following table summarizes the Company's restricted stock unit activity:

The total fair value of shares that vested during the three -months ended June 30, 2017 and 2016 was $1,894 and $2,039 , respectively.

As of June 30, 2017 , there was $4,165 of total unrecognized pre-tax stock-based compensation expense related to non-vested restricted stock units, which is expected to be recognized over a weighted-average period of 2.3 years.

Performance share awards

Performance share awards are subject to one of the performance goals - the Company's Relative Total Shareholder Return ("TSR") Ranking or cumulative Adjusted EBITDA - each over a three -year period. The Company's Relative TSR Ranking metric is based on the three-year cumulative return to stockholders from the change in stock price and dividends paid between the starting and ending dates. The fair value of performance share awards (subject to cumulative Adjusted EBITDA) is determined based on the number of performance shares granted and the closing market price of the common stock on the date of grant. The fair value of performance share awards (subject to the Company's Relative TSR Ranking) is estimated on the grant date using the Monte-Carlo simulation valuation method which includes the following weighted-average assumptions.

The following table summarizes the Company's performance share award activity:

The total fair value of shares that vested during the three -months ended June 30, 2017 and 2016 was $0 and $0 , respectively, as there were no payouts because certain performance obligations were not met.

As of June 30, 2017 , there was $2,598 of total unrecognized pre-tax stock-based compensation expense related to non-vested performance share awards, which is expected to be recognized over a weighted-average period of 2.5 years.

Note 11: Earnings (loss) Per Share

The following table details the computation of basic and diluted earnings (loss) per common share from continuing operations for the periods presented (share numbers in table in thousands):

The Weighted-average common shares outstanding (diluted) computation is not impacted during any period where the exercise price of a stock option is greater than the average market price. There were 1,796,632 and 1,071,297 non-dilutive equity awards outstanding for the three-months ended June 30, 2017 and 2016 , respectively, that are not included in the corresponding period Weighted-average common shares outstanding (diluted) computation.

Note 12: Segment Information

The Company conducts business globally and is managed on a geographic-service type basis consisting of four operating segments which are (i) North America Products, (ii) North America Services, (iii) International Products and (iv) International Services. These operating segments are also the Company's reporting units for purposes of testing goodwill for impairment and its reporting segments for financial reporting purposes. Revenues within our North America segments are primarily attributed to the United States while revenues within our International segments are attributed to countries in Europe, the Pacific Rim and Latin America.

The accounting policies of the operating segments are the same as those of the Company. The Company allocates resources to its operating segments and evaluates the performance of the operating segments based upon operating income.

The financial results for the Company's reporting segments are as follows:

Note 13: Commitments and Contingencies

In connection with the Amended Credit Agreement disclosed in Note 5, the Company is required to make payments of $3,750 on its term loan over the next 12-months. Correspondingly, the Company expects its long-term payments (greater than 1 year) under the credit facility to decrease by $3,750.

The Company is involved in, or has pending, various legal proceedings, claims, suits and complaints arising out of the normal course of business. Based on the facts currently available to the Company, Management believes these matters are adequately provided for, covered by insurance, without merit or not probable that an unfavorable material outcome will result.

There has been no other significant or unusual activity during Fiscal 2018 .

Note 14: Restructuring

The Company has incurred and continues to incur costs related to facility consolidations, such as idle facility rent obligations and the write-off of leasehold improvements, and employee severance (collectively referred to as "restructuring expense") in a continued effort to consolidate back office functions and to make its organization more efficient. These restructuring activities are compartmentalized and are not part of an overall plan and therefore the Company cannot estimate the total amount to be incurred in connection with the activity. Employee severance is generally payable within the next twelve months with certain facility costs extending through Fiscal 2019.

The following table summarizes the changes to the restructuring liability for the periods presented.

Of the $7,325 above, $7,243 is classified as a current liability under Other liabilities on the Company's Consolidated Balance Sheets for the period ended June 30, 2017 .

The following table summarizes restructuring expense, which is recorded in Selling, general & administrative expenses in the Company's Consolidated Statements of Operations, for the three months ended June 30, 2017 , for the Company's reporting segments:

Company management is considering initiatives to reset the business model and align costs with revenue to improve profitability. As a result, during FY18 , our profits could be negatively impacted by restructuring expenses resulting from such initiatives, which are designed to maximize the efficiency of the cost structure for each of our segments to enhance the Company's profitability. The Company believes there is a significant cost savings for such restructuring initiatives that will provide a return on investment in a relatively short period of time. However, there can be no assurance that we would realize adequate returns on this investment nor that we would be able to maintain such cost savings in the future. Such restructuring initiatives have not been formalized and the Company cannot state with any certainty the timing or whether or not such events will occur.

The discussion and analysis for the three-months June 30, 2017 and 2016 as set forth below in this Part I, Item 2 should be read in conjunction with the response to Part I, Item 1 of this report and the consolidated financial statements of Black Box Corporation ("Black Box," the "Company," "we" or "our"), including the related notes, and "Management's Discussion and Analysis of Financial Condition and Results of Operations" included in the Company's most recent Annual Report on Form 10-K, as filed with the Securities and Exchange Commission ("SEC") for the fiscal year ended March 31, 2017 (the "Form 10-K"). References to " 1Q18 " mean the three-month period ended June 30, 2017 while references to " 1Q17 " mean the three-month period ended June 30, 2016 . The Company's fiscal year ends on March 31. The fiscal quarters consist of 13  weeks and generally end on the Saturday nearest each calendar quarter end, adjusted to provide relatively equivalent business days for each fiscal quarter. The actual ending dates for the periods presented as of June 30, 2017 and 2016 were July 1, 2017 and July 2, 2016 , respectively. References to "Fiscal Year" or "Fiscal" mean the Company's fiscal year ended March 31 for the year referenced. All dollar amounts are presented in thousands except for per share amounts or unless otherwise noted.

The Company

Black Box is a leading digital solutions provider dedicated to helping customers design, build, manage and secure their IT infrastructure. The Company offers Services and Products that it distributes through two platforms that it has built over its 41 -year history.

Our Services platform is comprised of engineering and design, project management, field service management, network operations centers, our national technology team, national and international sales teams and technology solutions centers which include dedicated sales and engineering resources. The primary services offered through this platform include managed services, infrastructure services (including wired and wireless network solutions, structured cabling and video/AV services), communications lifecycle services, unified communications and data center services.

The Company generates revenues in its Services business from the design, sale and/or installation of new communications and network infrastructure systems, the support of existing systems and moves, adds and changes ("MAC work"). We periodically generate revenues from contracts performed over time that may result in an asset on our balance sheet for multiple periods constituting part of our working capital. We have not experienced significant collectability issues related to such contracts. For the sale and implementation of new communications systems or other major projects, most significant orders are subject to competitive bidding processes and, generally, competition can be significant for such new orders. The Company is continually bidding on new projects for service revenues. Projects account for the majority of Services revenues and are primarily driven by the overall economic environment and information technology capital spending. The Company also serves government clients whose revenues are not as dependent on the overall economic environment as commercial clients but are subject to governmental budgetary constraints.

New communications systems orders often generate post-implementation maintenance via a fixed fee model where revenues are earned ratably over the term of the agreement (generally 1-3 years for commercial clients and 3-5 years for government clients) or a variable fee model that is based on time and materials per occurrence, similar to MAC work. Maintenance revenues generally are not dependent on the economy as clients contract for maintenance to extend the life of their existing equipment and delay capital spending on new communications systems. Maintenance and MAC work revenues are also dependent upon the Company's relationship with its clients and its long track record of providing high-quality service.

The Company's Services business generates backlog which is defined by the Company as orders and contracts considered to be firm. At June 30, 2017 , the Company's total backlog, which relates primarily to Services, was $283,357 , of which $208,555 is expected to be completed within the next twelve months.

Under our Products platform, we provide networking solutions through the sale of products for KVM switching, IT infrastructure, specialty networking and multimedia.

Our Products' revenues are generated from sales to key channel partners and system integrators and through a global distribution network. Products sells through a direct sales team as well as through its internet site and catalogs. In order to meet client demand, we keep a moderate level of inventory which consumes part of our working capital. The market for these products is a highly fragmented and competitive. The Company has participated in this market for 40+ years and has earned a reputation for providing high quality products, rapid order fulfillment and free 24/7/365 technical support. The Company's Products revenue is driven both by general information technology spending and capital budgets.

Our platforms introduce scale, flexibility and leverage to the business, and provide the following competitive advantages:

The Company services a variety of clients within most major industries, with the highest concentration in the government, business services, manufacturing, banking, retail, healthcare and technology industry verticals. Factors that impact those verticals, therefore, could have an impact on the Company. While the Company generates most of its revenues in North America, the Company also generates revenues from around the world, primarily Europe, such that factors that impact European markets could impact the Company. Management strives to develop extensive and long-term relationships with high-quality clients as Management believes that satisfied clients will demand quality services and product offerings from us even in economic downturns.

1Q18 vs 1Q17 Summary

n/m = not meaningful

Diluted loss per share was $0.65 , compared to $0.03 in the same period last year as a result of:

Net cash used for operating activities was $16,267 , which included Net loss of $9,747 and negative cash from working capital of $8,907 , compared to net cash provided for operating activities of $10,884 , which included Net loss of $476 and positive cash from working capital of $2,313 , in the same period last year.

Results of Operations

Segments

We conduct our business globally and manage our business by geographic-service type under the following four operating segments: North America Products, North America Services, International Products and International Services. The Revenues, Gross profit and Operating income (loss) amounts in the table below are presented on a basis consistent with GAAP.

1Q18 vs 1Q17

Total Revenues were $191,644 , a decrease of 12% from $218,480 in the same period last year. Service Revenues were $158,756 , a decrease of 11% from $178,599 in the same period last year due to a decrease in commercial revenues partially offset by an increase in government revenues. The decrease in commercial revenues within North America is due to a decline in the legacy unified communication business, which we expect will continue for the foreseeable future, and a decrease in the infrastructure business, which is the result of a change in sales leadership and other transformational activities. Government revenues increased due to market repositioning that was actioned over the past two years. Product Revenues were $32,888 , a decrease of 18% from $39,881 in the same period last year primarily due to a decrease in North America Products' sales as a result of lower demand in the legacy run rate business and a decline in International Products which was negatively impacted by an initiative to centralize back office and supply chain operations.

Total Gross profit margin was 27.4% , a decrease of 11% from 31.0% in the same period last year. Service Gross profit margin was 24.4% , a decrease of 14% from 28.4% in the same period last year primarily due to lower revenues on higher margin unified communication business and aggressive pricing on certain incremental infrastructure projects for our commercial clients and higher volume of successful contract awards that carry a lower gross margin for our government clients. Product Gross profit margin was 42.1% , a decrease of 1% from 42.5% in the same period last year primarily due to a decrease in North America Products because of margin compression on data communication and infrastructure products partially offset by a slight increase in International Products gross margin.

Total Operating loss margin was 6.7% , compared to Total Operating profit margin of 1.2% in the same period last year. Service Operating loss margin was 4.8% , compared to Service Operating profit margin of 0.8% in the same period last year, primarily due to lower gross margins in North America Services as discussed above, an increase of $1,278 for restructuring expense, an increase of $3,000 of costs related to ERP implementation and a $1,175 gain on facility that was sold last year. The Company will continue to incur costs associated with the U.S.-based ERP project during the remainder of FY18 that will have a negative impact on our profits and cash flows. Product Operating loss margin was 15.9% , compared to Product Operating profit margin of 3.2% in the same period last year, primarily due to lower gross margins in North America Products as discussed above, and an increase of $1,306 and $1,713 for restructuring expense in North America Products and International Products, respectively.

Company management continues to review initiatives to align costs with revenue to improve profitability. As a result, during FY18 , our profits could be negatively impacted by restructuring expenses resulting from such initiatives, which are designed to maximize the efficiency of the cost structure for each of our segments to enhance the Company's profitability. The Company believes there is a significant cost savings for such restructuring initiatives that will provide a return on investment in a relatively short period of time. However, there can be no assurance that we would realize adequate returns on this investment nor that we would be able to maintain such cost savings in the future. Such restructuring initiatives have not been formalized and the Company cannot state with any certainty the timing or whether or not such events will occur.

Interest expense, net and Income Taxes

1Q18 vs 1Q17

Interest expense was $1,218 , an increase of 1% from $1,207 in the same period last year primarily as a result of higher weighted-average debt. Interest expense as a percent of Revenues was 0.6% , compared to 0.6% in the same period last year. The weighted-average outstanding debt and weighted-average interest rate was $140,455 and 2.8% , respectively, compared to $133,299 and 2.5% in the same period last year.

Benefit from income taxes was $4,498 , compared to a provision for income taxes of $2,332 in the same period last year. The effective income tax rate was 31.6% , a decrease from 125.6% in the same period last year. The effective income tax rate decrease from 125.6% to 31.6% was primarily due to the current mix of income and losses in various taxing jurisdictions and a release of uncertain income tax positions that produced a benefit in the prior year.

Liquidity and Capital Resources

Overview

A majority of our revenue is generated through individual sales of services and products. Less than 20% of our revenue is generated from long-term support contracts. We depend on repeat client business, as well as our ability to develop new client business, to sustain and grow our revenue. Most significant orders are subject to a competitive bidding process and, generally, competition can be significant for such new orders. Our business model provides us with flexibility in terms of capital expenditures and other required operating expenses. For the foreseeable future, we expect that the combination of net cash provided by operating activities and the available borrowings under our line of credit will be sufficient to fund our capital expenditures and other required operating expenses and will be available for discretionary investments.

We seek to allocate company resources in a manner that will enhance per share results. Our discretionary investments include: investments in growth programs and infrastructure, strategic acquisitions of high quality growth-oriented companies and repaying our debt.

Liquidity Position

The following is a summary of our capitalization and liquidity position.

The Company's reported cash balance is at its lowest level since March 31, 2006 due to more efficient usage of international cash balances. We do not expect any further significant reduction in the amount of cash on our balance sheet because we are limited by a combination of factors such as protected currencies, adverse tax impacts and other operating needs or requirements. The Company's reported working capital continues at a historically low level due to an increased focus around a reduction of working capital. The Company's reported long-term debt continues at a historically low level due to the results of reduced working capital and cash efficiencies discussed above and a priority placed on debt reduction.

On August 9, 2017, the Company and certain Banks entered into an Amendment and Joinder Agreement. See Note 5 of the Notes to the Consolidated Financial Statements and Item 1A. Risk Factors within Part II of this Quarterly Report on (this "Form 10-Q") for additional reference.

Sources and Uses of Cash

The following is a summary of our sources and uses of cash.

Net cash provided by (used for) operating activities

Net cash used for operating activities was $16,267 , due primarily to Net loss of  $9,747 , inclusive of non-cash charges, cash outflows of $11,230, $6,095, and $4,452 for All other liabilities, Accounts payable and All other assets, respectively, partially offset by cash inflows of $15,238 for Accounts receivable, compared to net cash provided by operating activities of $10,884 in the same period last year, due primarily to Net loss of $476, inclusive of non-cash charges, cash inflows of $4,590 and $2,305 for Accounts receivable and Inventories, respectively, partially offset by cash outflows of $3,553 for Costs/estimated earnings in excess of billings on uncompleted contracts. Changes in the above accounts are based on average Fiscal 2018 and Fiscal 2017 exchange rates, as applicable.

Changes in working capital, and particularly changes in Accounts receivable, Costs in excess of billings and Billings in excess of cost, can have a significant impact on net cash provided by operating activities, largely due to the timing of payments and receipts.

Net cash provided by (used for) investing activities

Capital expenditures

The Company made investments of $1,097 compared to $2,072 in the same period last year which primarily related to information technology infrastructure, computer hardware and software and vehicles.

Net cash provided by (used for) financing activities

Long-term debt

Proceeds from long-term debt was $10,172 compared to repayments of long-term debt of $4,807 in the same period last year.

Common stock repurchases

The Company made discretionary investments in the form of common stock repurchases of $0 compared to $0 in the same period last year. The Company also made tax payments of $393 compared to $477 in the prior year related to share withholding to satisfy employee income taxes due as a result of the vesting of certain restricted stock units.

Since the inception of the repurchase program beginning in April 1999 through June 30, 2017 , the Company has repurchased 11,392,851 shares of common stock for an aggregate purchase price of $408,621 , or an average purchase price per share of $35.87 . These shares do not include the treasury shares withheld for tax payments due upon the vesting of certain restricted stock units and performance shares. Under the Amended Credit Agreement, the Company is no longer permitted to repurchase common stock through its repurchase program but is allowed to repurchase a limited amount of shares for tax payments related to the vesting certain restricted stock units and performance shares, as applicable. This restriction is in effect until May 9, 2021. The Company expects to use the funds that were previously available for stock repurchases to supplement spending for our previously announced U.S.-based ERP project and to develop and implement growth initiatives for the Company, both of which we believe will create long-term shareholder value. See Note 5 of the Notes to the Consolidated Financial Statements contained in Part I of this Quarterly Report for additional information.

Dividends

While the Company has paid dividends for the past 49 quarters, it is no longer permitted to do so under the Amended Credit Agreement. The Company expects to use the funds that were previously available for dividends to supplement spending for our previously announced US-based ERP project and to develop and implement growth initiatives for the Company, both of which we believe will create long-term shareholder value. This restriction is in effect until May 9, 2021. See Note 5 of the Notes to the Consolidated Financial Statements contained in Part I of this Quarterly Report for additional information.

Credit Agreement

On August 9, 2017, the Company and certain Banks entered into an Amendment and Joinder Agreement. See Note 5 of the Notes to the Consolidated Financial Statements contained in Part I of this Quarterly Report and Item 1A. Risk Factors contained in Part II of this Form 10-Q for additional information.

Valuation of long-lived assets

During the first quarter of Fiscal 2018, the Company lowered its projections of revenue and profitability outlook for the foreseeable future. During the second quarter of Fiscal 2018, the Company will conduct an interim assessment of our both our definite-lived and indefinite lived intangible assets and determine whether such assets were recoverable as of July 1, 2017. If such assets are not recoverable, the Company could incur a non-cash impairment charge, which could have a material adverse effect on our consolidated balance sheet and results of operations.

Legal Proceedings

See Note 13 of the Notes to the Consolidated Financial Statements of this Form 10-Q, which information is incorporated herein by reference.

Inflation

The overall effects of inflation on the Company have been nominal. Although long-term inflation rates are difficult to predict, the Company continues to strive to minimize the effect of inflation through improved productivity and cost reduction programs as well as price adjustments within the constraints of market competition.

Critical Accounting Policies

The Company's critical accounting policies require the most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain and are the most important to the portrayal of the Company's consolidated financial statements. The Company's critical accounting policies are disclosed in Part II, Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations" of the Form 10-K. The significant accounting policies used in the preparation of the Company's consolidated financial statements are disclosed in Note 2 of the Notes to the Consolidated Financial Statements within the Form 10-K. No additional significant accounting policies have been adopted during Fiscal 2018 .

Impact of Recently Issued Accounting Pronouncements

There have been no accounting pronouncements adopted during Fiscal 2018 that have had a material impact on the Company's consolidated financial statements.

Any forward-looking statements contained in this Quarterly Report on Form 10-Q or in documents incorporated herein by reference are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 and speak only as of the date of this Form 10-Q.

The Company is exposed to market risks in the ordinary course of business that include interest-rate volatility and foreign currency exchange rates volatility. Market risk is measured as the potential negative impact on earnings, cash flows or fair values resulting from a hypothetical change in interest rates or foreign currency exchange rates over the next year. The Company does not hold or issue any other financial derivative instruments (other than those specifically noted below) nor does it engage in speculative trading of financial derivatives.

Interest-rate Risk

The Company's primary interest-rate risk relates to its long-term debt obligations under the Credit Agreement which was $102,528 as of June 30, 2017 . As of June 30, 2017 , an instantaneous 100 basis point increase in the interest rate of the variable rate debt would reduce the Company's earnings in the subsequent fiscal quarter by $260 ( $159 net of tax) assuming the Company employed no intervention strategies. The Company expects that its interest rates under the Amended Credit Agreement will be higher than the interest rates under the Credit Agreement thus increasing its exposure to interest on variable rate debt.

Foreign Exchange Rate Risk

The Company has operations, clients and suppliers worldwide, thereby exposing the Company's financial results to foreign currency fluctuations. In an effort to reduce this risk of foreign currency fluctuations, the Company generally sells and purchases inventory based on prices denominated in U.S. dollars. Intercompany sales to subsidiaries are generally denominated in the subsidiaries' local currency. The Company has entered and will continue in the future, on a selective basis, to enter into foreign currency contracts to reduce the foreign currency exposure related to certain intercompany transactions, primarily trade receivables and loans. All of the foreign currency contracts have been designated and qualify as cash flow hedges. The effective portion of any changes in the fair value of the derivative instruments is recorded in Accumulated Other Comprehensive Income ("AOCI") until the hedged forecasted transaction occurs or the recognized currency transaction affects earnings. Once the forecasted transaction occurs or the recognized currency transaction affects earnings, the effective portion of any related gains or losses on the cash flow hedge is reclassified from AOCI to the Company's Consolidated Statements of Operations. In the event it becomes probable that the hedged forecasted transaction will not occur, the ineffective portion of any gain or loss on the related cash flow hedge would be reclassified from AOCI to the Company's Consolidated Statements of Operations.

As of June 30, 2017 , the Company had open foreign currency contracts in Australian and Canadian dollars, Danish krone, Euros, Mexican pesos, Norwegian kroner, British pounds sterling, Swedish krona, Swiss francs and Japanese yen. The open contracts have contract rates ranging from 1.29 to 1.36 Australian dollar, 1.29 to 1.36 Canadian dollar, 6.45 to 7.06 Danish krone, 0.87 to 0.95 Euro, 18.37 to 18.37 Mexican peso, 8.25 to 8.58 Norwegian kroner, 0.76 to 0.78 British pound sterling, 8.31 to 8.69 Swedish krona, 0.95 to 1.02 Swiss franc and 111.40 to 114.71 Japanese yen, all per U.S. dollar. The total open contracts had a notional amount of $49,069 and will expire within four months.

Conclusions Regarding the Effectiveness of Disclosure Controls and Procedures

Management, including the Company's Chief Executive Officer and Chief Financial Officer, is responsible for establishing and maintaining adequate disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act")), for the Company. Management assessed the effectiveness of the Company's disclosure controls and procedures as of July 1, 2017 . Based upon this assessment, Management has concluded that the Company's disclosure controls and procedures were effective as of July 1, 2017 to provide reasonable assurance that information required to be disclosed by the Company in the reports filed or submitted by it under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, and to provide reasonable assurance that information required to be disclosed by the Company in such reports is accumulated and communicated to Management, including its principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

There have not been any changes in the Company's internal control over financial reporting (as such term is defined in Rules  13a-15(f) and 15d-15(f) of the Exchange Act) during the most recent fiscal quarter that have materially affected or are reasonably likely to materially affect the Company's internal control over financial reporting.

Limitations on the Effectiveness of Controls

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Because of its inherent limitations, the Company's internal control over financial reporting may not prevent or detect misstatements. In addition, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies and procedures may deteriorate.

The following is provided to update the following risk factor previously disclosed in Part I, Item 1A, Risk Factors of the Form 10-K.

We can provide no assurance that we will continue to have adequate liquidity . Our working capital demands can fluctuate greatly due to cash needs to fund new client contracts in advance of contractual payment dates. Due to our decreased revenues and profitability, and increased investments in our business under our transformation efforts, such as ERP migrations previously disclosed, net cash provided by operating activities may be insufficient to fund our operations and growth initiatives. We are dependent upon our senior credit facility to fund our cash needs. We recently amended our senior credit agreement to avoid a default of our leverage covenant. Our amended credit agreement contains covenants requiring us to achieve a certain minimum adjusted EBITDA during each quarter through the first quarter of Fiscal 2019. A leverage ratio and a fixed charge coverage ratio commence in the second quarter of Fiscal 2019 through maturity in May 2021. There can be no assurance that we will be able to remain in compliance with these or other covenants in our amended credit agreement. If we default the amended credit facility, the lenders would have the ability to exercise all of their legal and contractual remedies for default including, among others, the right to cease extending credit under the facility, to declare all outstanding obligations under the credit facility (including all outstanding indebtedness) to be immediately due and payable, to take action to protect its security interests in the collateral (which is substantially all of the assets of the Company) including taking possession thereof, and to increase the interest rate under the facility. In the event of a future default, although we could undertake activities to generate cash and repay the indebtedness under the amended credit facility, such as asset sales, or could seek to refinance such indebtedness with new indebtedness and/or sales of securities, there can be no assurance that such efforts would be successful. As a result, a default under the amended credit agreement could have a material adverse effect on the Company.

(b) As previously disclosed, on May 24, 2017 our Board of Directors amended our Amended and Restated By-laws (the "By-laws") to provide that certain eligible stockholders or groups of stockholders will be entitled to include a certain number of their nominees in the Company's proxy statement for its annual meeting, beginning in 2018 ("proxy access") provided the requirements set forth in the By-laws are met on a timely basis. Please refer to our By-laws for the details regarding our proxy access provisions.
