The Company
The Company	Note 1 — The Company Hill International, Inc. (“Hill” or the “Company”) is a professional services firm that provides program management, project management, construction management and other consulting services primarily to the buildings, transportation, environmental, energy and industrial markets worldwide. Hill’s clients include the U.S. federal government, U.S. state and local governments, foreign governments and the private sector.

Liquidity

Liquidity	3 Months Ended

Liquidity
Liquidity	Note 2 - Liquidity The amount of consulting fee revenue (“CFR”) attributable to operations in the Middle East and Africa is approximately 45.5% of total consolidated CFR for the three months ended March 31, 2017. There has been significant political upheaval and civil unrest in this region, most notably in Libya and Iraq where the Company had substantial operations. In 2012, due to the overthrow of the Libyan government, the Company reserved a $59,937,000 receivable from the Libyan Organization for Development of Administrative Centres (“ODAC”). Subsequently, the Company received payments totaling approximately $9,511,000. During the quarter ended March 31, 2017, the Company wrote off approximately $3,593,000 and maintains a reserve of approximately $2,777,000 against accounts receivable from various projects in Iraq. This shortfall of cash flows continues to put a considerable strain on its liquidity. The Company continues to experience slowing of collections from its clients in the Middle East, primarily Oman. In 2012, the Company commenced operations on the Muscat International Airport (the “Oman Airport”) project with the Ministry of Transport and Communications (the “MOTC”) in Oman. The original contract term expired in November 2014. In October 2014, the Company applied for a twelve-month extension of time amendment (the “first extension”) which was subsequently approved in March 2016 and the Company continued to work on the Oman Airport project. The Company began to experience some delays in payment during the second quarter of 2015 when MOTC commenced its formal review and certification of the Company’s invoices. In October 2015, the MOTC paid the Company for work performed in April and May 2015. In December 2015, the Company began discussions with the MOTC on a second extension of time amendment (“the second extension”) and has since commenced additional work, which management expects to last through approximately June 2018. MOTC resumed payments in 2016 paying the Company approximately $42,000,000 during 2016 and $12,728,000 through April 2017. At March 31, 2017, accounts receivable from the Oman Airport totaled approximately $29,200,000, of which approximately $18,700,000 was past due based on contractual terms. The delays in payments from MOTC and other foreign governments have had a negative impact on the Company’s liquidity, financial covenants, financial position and results of operations. As a result, the Company has had to rely heavily on debt and equity transactions to fund its operations over the past few years.

Discontinued Operations
Discontinued Operations	Note 3 - Discontinued Operations In early 2016, the Company began to investigate the sale of its Construction Claims Group (the “Claims Group”). The pending sale of that segment represents a strategic shift that will have a major effect on its operations and financial results. Accordingly, the Company had classified the assets and liabilities of that segment as held for sale and has reflected its operations and cash flows as discontinued operations for all periods presented. On December 20, 2016, the Company and its subsidiary Hill International N.V. (“Hill N.V.” and, collectively with the Company, the “Sellers”) entered into a Stock Purchase Agreement (as amended on May 3, 2017, the “Agreement”) with Liberty Mergeco, Inc. (the “US Purchaser”) and Liberty Bidco UK Limited (the “UK Purchaser” and, collectively with the US Purchaser, the “Purchasers”) pursuant to which the Purchasers will acquire the Claims Group by the US Purchaser’s acquisition of all of the stock of Hill International Consulting, Inc. from the Company and the UK Purchaser’s acquisition of all of the stock of Hill International Consulting B.V. from Hill N.V. for a total purchase price of $140,000,000 in cash reduced by assumed indebtedness and certain other items, as set forth in the Agreement. The transaction closed effective May 5, 2017. See Note 18 for further information. The carrying amounts of assets and liabilities of the discontinued operations which have been classified as held for sale are as follows (in thousands): March 31, 2017 December 31, 2016 Trade receivables $ $ Prepaid expense and other current assets Income taxes receivable Total current assets classified as held for sale $ $ Property, plant and equipment Acquired intangibles, net Goodwill Investments Deferred income tax assets Other assets Total non-current assets classified as held for sale $ $ Accounts payable Income taxes payable Deferred revenue Other current liabilities Total current liabilities classified as held for sale $ $ Deferred income taxes Deferred revenue Other liabilities Total non-current liabilities classified as held for sale $ $ The line items constituting earnings from discontinued operations consist of the following (in thousands): March 31, 2017 2016 Consulting fee revenue $ $ Reimbursable expenses Total revenue Cost of services Reimbursable expenses Total direct expenses Gross profit Selling, general and administrative expenses Operating (loss) profit ) Interest and related financing fees, net Loss before income taxes ) ) Income tax expense Net loss from discontinued operations $ ) $ ) In connection with the sale of the Construction Claims Group, the Company will be required to pay off the Secured Credit Facilities (See Note 9). Accordingly, the Company has allocated to discontinued operations all interest expense related to the Secured Credit Facilities. During the first quarter of 2017, the Company charged to discontinued operations approximately $1,585,000 of costs related to the pending sale of the Construction Claims and $410,000 for a potential tax liability related to foreign jurisdictions. See Notes 17 and 18 for further information.

Basis of Presentation	Note 4 — Basis of Presentation Basis of Presentation The accompanying unaudited interim consolidated financial statements were prepared in accordance with the rules and regulations of the Securities and Exchange Commission pertaining to reports on Form 10-Q and should be read in conjunction with the consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States (“GAAP”) for complete financial statements. In the opinion of management, these statements include all adjustments (consisting only of normal, recurring adjustments) necessary for a fair presentation of the consolidated financial statements. The consolidated financial statements include the accounts of Hill and its wholly- and majority-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. The preparation of financial statements in conformity with GAAP requires 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. Actual results could differ from those estimates. The interim operating results are not necessarily indicative of the results for a full year.

In 2012, the Company commenced operations on the Muscat International Airport (the “Oman Airport”) project with the Ministry of Transport and Communications (the “MOTC”) in Oman. The original contract term expired in November 2014. In October 2014, the Company applied for a twelve-month extension of time amendment (the “first extension”) which was subsequently approved in March 2016 and the Company continued to work on the Oman Airport project. The Company began to experience some delays in payment during the second quarter of 2015 when MOTC commenced its formal review and certification of the Company’s invoices. In December 2015, the Company began discussions with the MOTC on a second extension of time amendment (the “second extension”) and has since commenced additional work, which management expects to last approximately 18 months. When the MOTC resumed payments in 2016, the Company received approximately $42,000,000 during the year. At March 31, 2017, accounts receivable from the Oman Airport totaled approximately $29,200,000, of which approximately $18,700,000, was past due based on contractual terms. Through April 2017, the Company received payments totaling $12,728,000 against this receivable. In addition, there is approximately $17,000,000 included in non-current Retainage Receivable in the consolidated balance sheet at March 31, 2017. Of that amount, approximately $8,400,000 relates to retention and approximately $8,600,000 relates to a Defect and Liability Period (“DLP”). Retention represents five percent of each monthly invoice which is retained by MOTC. Fifty percent of the retention will be released one year from the commencement of the DLP and the balance will be released upon the issuance of final Completion Certificates. DLP represents the period by which the contractor must address any defect issues. This period commences upon the issuance of a “Taking Over Certificate” (by MOTC) to contractors for up to a period of 24 months and ends with a final certificate closing the project. The delays in payments from MOTC and other foreign governments have had a negative impact on the Company’s liquidity, financial covenants, financial position and results of operations.

The disclosures which follow below describe the Secured Credit Facilities in existence as of March 31, 2017. The Company and its subsidiary Hill International N.V. (the “Subsidiary”) are parties to a credit agreement with Société Générale (the “Agent”), TD Bank, N.A. and HSBC Bank USA, N.A. (collectively, the “U.S. Lenders”) consisting of a term loan facility of $120,000,000 (the “Term Loan Facility”) and a $30,000,000 U.S. dollar-denominated facility available to the Company (the “U.S. Revolver,” together with the Term Loan Facility, the “U.S. Credit Facilities”) and a credit agreement with the Agent (the “International Lender”) providing ac €11,765,000 ($15,000,000 at closing and $12,573,000 at March 31, 2017) credit facility which is available to the Subsidiary (the “International Revolver” and together with the U.S. Revolver, the “Revolving Credit Facilities” and, together with the U.S. Credit Facilities, the “Secured Credit Facilities”). The U.S. Revolver and the International Revolver include sub-limits for letters of credit amounting to $25,000,000 and $10,000,000, respectively. The Secured Credit Facilities contain customary default provisions, representations and warranties, and affirmative and negative covenants, and require the Company to comply with certain financial and reporting covenants. The financial covenants consist of a Maximum Consolidated Net Leverage Ratio and an Excess Account Concentration requirement. The Consolidated Net Leverage Ratio is the ratio of (a) consolidated total debt (minus cash of up to $10,000,000 held in the aggregate) to (b) consolidated earnings before interest, taxes, depreciation, amortization, non-cash items and share-based compensation and other non-cash charges, including bad debt expense, for the trailing twelve months. In the event of a default, the U.S. Lenders and the International Lender may increase the interest rates by 2.0%. The Excess Account Concentration covenant permits the U.S. Lenders and the International Lender to increase the interest rates by 2.0% if, as of the last day of any fiscal quarter, either (a) the accounts receivable from any country not listed as a Permitted Country as defined in the Secured Credit Facilities (other than the United Arab Emirates) that are more than 120 days old (relative to the invoice date) constitute more than 10% of the total outstanding accounts receivable or (b) accounts receivable from any individual client located in the United Arab Emirates that are more than 120 days old (relative to the invoice date) constitute more than 14% of the total outstanding accounts receivable. The interest rate will be reset as soon as the accounts receivable over 120 days decline below the 10% or 14% levels. At March 31, 2017, the accounts receivable from Oman exceeded the limit described above, however, due to a payment received on April 12, 2017, the accounts receivable declined below the established limit. At December 31, 2016, the Company was in default of the Consolidated Net Leverage Ratio. The Company requested and received a waiver of the default from the Agent on March 27, 2017. In connection with the waiver, the Company incurred a consent fee amounting to $401,000 which was charged to discontinued operations in the first quarter of 2017. The U.S. Credit Facilities are guaranteed by certain U.S. subsidiaries of the Company, and the International Revolver is guaranteed by the Company and certain of the Company’s U.S. and non-U.S. subsidiaries. Term Loan Facility The interest rate on the Term Loan Facility will be, at the Company’s option, either: · the London Inter-Bank Offered Rate (“LIBOR”) for the relevant interest period plus 6.75% per annum, provided that such LIBOR shall not be lower than 1.00% per annum; or · the Base Rate (as described below) plus 5.75% per annum. The “Base Rate” is a per annum rate equal to the highest of (A) the prime rate, (B) the federal funds effective rate plus 0.50%, or (C) the LIBOR for an interest period of one month plus 1.0% per annum. Upon a default, the applicable rate of interest under the Secured Credit Facilities may increase by 2.0%. The LIBOR on the Term Loan Facilities (including when determining the Base Rate) shall in no event be less than 1.0% per annum. At March 31, 2017, the interest rate on the Term Loan was 7.75%. The Company has the right to prepay the Term Loan Facility in full or in part at any time without premium or penalty. The Company is required to make mandatory prepayments of the Term Loan Facility, without premium or penalty, (i) with net proceeds of any issuance or incurrence of indebtedness (other than that permitted under the Term Loan Facility) by the Company after the closing, (ii) with net proceeds from certain asset sales outside the ordinary course of business, and (iii) with 50% of the excess cash flow (as defined in the agreement) for each fiscal year of the Borrowers commencing with the first full fiscal year ending after closing (which percentage would be reduced to 25% if the Consolidated Net Leverage Ratio is equal to or less than 2.25 to 1.00 or reduced to 0% if the Consolidated Net Leverage Ratio is equal to or less than 1.50 to 1.00). The Term Loan Facility is generally secured by a first-priority security interest in substantially all assets of the Company and certain of the Company’s U.S. subsidiaries other than accounts receivable, cash proceeds thereof and certain bank accounts, as to which the Term Loan Facility is secured by a second-priority security interest. The Term Loan Facility has a term of six years, requires repayment of 0.25% of the original principal amount on a quarterly basis through September 30, 2020, the maturity date. Any amounts repaid on the Term Loan Facility will not be available to be re-borrowed. The Company incurred fees and expenses related to the Term Loan Facility aggregating $7,066,000 which have been deferred. The deferred fees are being amortized on a straight-line basis, which approximates the effective interest method, to interest and related financing fees, net over a six-year period which ends on September 30, 2020. Unamortized balances of $4,122,000 and $4,416,000 are included as an offset against the Term Loan balances in the consolidated balance sheets at March 31, 2017 and December 31, 2016, respectively. Revolving Credit Facilities The interest rate on borrowings under the U.S. Revolver will be, at the Company’s option from time to time, either the LIBOR for the relevant interest period plus 3.75% per annum or the Base Rate plus 2.75% per annum. At March 31, 2017, the interest rate was 6.75%. The interest rate on borrowings under the International Revolver will be the European Inter-Bank Offered Rate, or “EURIBOR,” for the relevant interest period (or at a substitute rate to be determined to the extent EURIBOR is not available) plus 4.00% per annum. At March 31, 2017, the interest rate was 3.60%. The Company will pay a commitment fee calculated at 0.50% annually on the average daily unused portion of the U.S. Revolver, and the Subsidiary will pay a commitment fee calculated at 0.75% annually on the average daily unused portion of the International Revolver. The ability to borrow under each of the U.S. Revolver and the International Revolver is subject to a “borrowing base,” calculated using a formula based upon approximately 85% of receivables that meet or satisfy certain criteria (“Eligible Receivables”) and that are subject to a perfected security interest held by either the U.S. Lenders or the International Lender, plus, in the case of the International Revolver only, 10% of Eligible Receivables that are not subject to a perfected security interest held by the International Lender, subject to certain exceptions and restrictions. The Company or the Subsidiary, as applicable, will be required to make mandatory prepayments under their respective Revolving Credit Facilities to the extent that the aggregate outstanding amount thereunder exceeds the then-applicable borrowing base, which payments will be made without penalty or premium. At March 31, 2017, the domestic borrowing base was $30,000,000 and the international borrowing base was €11,765,000 (approximately $12,573,000 at March 31, 2017). Generally, the obligations of the Company under the U.S. Revolver are secured by a first-priority security interest in the above-referenced accounts receivable, cash proceeds and bank accounts of the Company and certain of the Company’s U.S. subsidiaries, and a second-priority security interest in substantially all other assets of the Company and such subsidiaries. The obligations of the Subsidiary under the International Revolver would generally be secured by a first-priority security interest in substantially all accounts receivable, cash proceeds thereof and certain bank accounts of the Subsidiary and certain of the Company’s non-U.S. subsidiaries, and a second-priority security interest in substantially all other assets of the Company and certain of the Company’s U.S. and non-U.S. subsidiaries. The Revolving Credit Facilities have a term of five years and require payment of interest only during the term. Under the Revolving Credit Facilities, outstanding loans may be repaid in whole or in part at any time, without premium or penalty, subject to certain customary limitations, and will be available to be re-borrowed from time to time through expiration on September 30, 2019. The Company incurred fees and expenses related to the Revolving Credit Facilities aggregating $3,000,000 which has been deferred. The deferred fees are being amortized on a straight-line basis, which approximates the effective interest method, to interest expense and related financing fees, net over a five-year period which ends on September 30, 2019. Unamortized balances of $1,500,000 and $1,650,000 are included in other assets in the consolidated balance sheet at March 31, 2017 and December 31, 2016, respectively. At March 31, 2017 the Company had $4,470,000 of outstanding letters of credit and $530,000 of available borrowing capacity under the U.S. Revolver. At March 31, 2017, the Company had $909,000 of outstanding letters of credit and $1,604,000 of available borrowing capacity under the International Revolver and its other foreign credit agreements (See “Other Debt Arrangements” below for more information). Other Debt Arrangements In connection with the 2015 move of its corporate headquarters to Philadelphia, Pennsylvania, the Company received a loan from the Philadelphia Industrial Development Corporation in the amount of $750,000 which bears interest at 2.75%, is repayable in 144 equal monthly installments of $6,121 and matures on May 1, 2027. The Company’s subsidiary, Hill International (Spain) S.A. (“Hill Spain”), maintained a revolving credit facility with six banks (the “Financing Entities”) in Spain which initially provided for total borrowing of up to €5,640,000 with interest at 6.50% on outstanding borrowings. The facility expired on December 17, 2016. Concurrent with the satisfaction of this facility Hill Spain entered into a new agreement with three new banks. The total new facility is for €2,623,000 (approximately $2,803,000) at March 31, 2017. The facility was fully utilized at March 31, 2017. Interest rates at March 31, 2017 were between 1.85% and 3.50%. The loans have varying expiration dates between 36 and 60 months. Hill Spain also maintains an ICO (Official Credit Institute) loan with Bankia Bank in Spain for €30,000 (approximately $32,000) at March 31, 2017. The availability is reduced by €15,000 on a quarterly basis. At March 31, 2017, the loan was fully utilized. The interest rate at March 31, 2017 was 6.50%. The ICO loan expires on August 10, 2017. The Company maintains a credit facility with the National Bank of Abu Dhabi which provides for total borrowings of up to AED 11,500,000 (approximately $3,131,000 at March 31, 2017) collateralized by certain overseas receivables. At March 31, 2017, AED 9,811,000 was utilized (approximately $2,671,000). The interest rate is the one-month Emirates InterBank Offer Rate plus 3.50% (or 4.91 % at March 31, 2017) but no less than 5.50%. This facility allows for letters of guarantee up to AED 200,000,000 (approximately $54,451,000 at March 31, 2017) of which AED 99,180,000 (approximately $27,002,000) was outstanding at March 31, 2017. The credit facility is subject to periodic review by the bank and as such has been classified as current in the consolidated balance sheet. Engineering S.A. maintains four unsecured revolving credit facilities with two banks in Brazil aggregating 2,380,000 Brazilian Reais (BRL) (approximately $755,000 at March 31, 2017, with a weighted average interest rate of 5.07% per month at March 31, 2017. There were no borrowings outstanding on any of these facilities which are renewed automatically every three months. The Company also maintains relationships with other foreign banks for the issuance of letters of credit, letters of guarantee and performance bonds in a variety of foreign currencies. At March 31, 2017, the maximum U.S. dollar equivalent of the commitments was $83,376,000 of which $33,177,000 is outstanding.

Dilutive stock options increased average common shares outstanding by 91,000 shares for the three-month period ended March 31, 2016. Options to purchase approximately 6,754,000 shares and 2,590,000 shares were excluded from the calculation of diluted earnings per share for the three-month periods ended March 31, 2017 and 2016, respectively, because they were antidilutive.

The Company’s effective tax rate represents the Company’s estimated tax rate for the year based on projected income and mix of income among the various foreign tax jurisdictions, adjusted for discrete transactions occurring during the period. The Company’s effective tax rate in both years is higher than it otherwise would be primarily as a result of not recording an income benefit related to the U.S. net operating loss. The components of (loss) earnings before income taxes and the related income tax expense by the United States and foreign jurisdictions were as follows (in thousands): Three Months Ended March 31, 2017 Three Months Ended March 31, 2016 U.S. Foreign Total U.S. Foreign Total (Loss) earnings before income taxes $ ) $ $ ) $ ) $ $ Income tax expense, net $ — $ $ $ — $ $ The reserve for uncertain tax positions amounted to $1,720,000 and $1,698,000 at March 31, 2017 and December 31, 2016, respectively, and is included in “Other liabilities” in the consolidated balance sheet at those dates. The Company’s policy is to record income tax related interest and penalties in income tax expense. At both March 31, 2017 and December 31, 2016, potential interest and penalties related to uncertain tax positions amounting to $228,000 and $206,000 at March 31, 2017 and December 31, 2016, respectively, were included in the balance above. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities and projected future taxable income in making this assessment. Management evaluates the need for valuation allowances on the deferred tax assets according to the provisions of ASC 740, Income Taxes. They consider both positive and negative evidence. In making this determination, management assesses all of the evidence available at the time including recent earnings, internally-prepared income projections, and historical financial performance.

Commitments and Contingencies
Commitments and Contingencies	Note 17 — Commitments and Contingencies General Litigation Knowles Limited (“Knowles”), a subsidiary of the Company, is a party to an arbitration proceeding instituted on July 8, 2014 in which Knowles claimed that it was entitled to payment for services rendered to Celtic Bioenergy Limited (“Celtic”). The arbitrator decided in favor of Knowles. The arbitrator’s award was appealed by Celtic to the U.K. High Court of Justice, Queen’s Bench Division, Technology and Construction Court (“Court”). On March 16, 2017, the Court (1) determined that certain relevant facts had been deliberately withheld from the arbitrator by an employee of Knowles and (2) remitted the challenged parts of the arbitrator’s award back to the arbitrator to consider the award in possession of the full facts. The Company is evaluating the impact of the judgment of the Court. From time to time, the Company is a defendant or plaintiff in various legal actions which arise in the normal course of business. As such the Company is required to assess the likelihood of any adverse outcomes to these matters as well as potential ranges of probable losses. A determination of the amount of the provision required for these commitments and contingencies, if any, which would be charged to earnings, is made after careful analysis of each matter. The provision may change in the future due to new developments or changes in circumstances. Changes in the provision could increase or decrease the Company’s earnings in the period the changes are made. It is the opinion of management, after consultation with legal counsel, that the ultimate resolution of these matters will not have a material adverse effect on the Company’s financial condition, results of operations or cash flows. Acquisition-Related Contingencies As of March 31, 2017 our subsidiary, Hill International (Spain), S.A. (“Hill Spain”), owned an indirect 91% interest in Engineering S.A. (“ESA”), a firm located in Brazil. ESA’s shareholders entered into an agreement whereby the minority shareholders have a right to compel (“ESA Put Option”) Hill Spain to purchase any or all of their shares during the period from February 28, 2014 to February 28, 2021. Hill Spain also has the right to compel (“ESA Call Option”) the minority shareholders to sell any or all of their shares during the same time period. The purchase price for such shares shall be seven times the earnings before interest and taxes for ESA’s most recently ended fiscal year, net of any financial debt plus excess cash multiplied by a percentage which the shares to be purchased bear to the total number of shares outstanding at the time of purchase, but in the event the ESA Call Option is exercised by Hill Spain, the purchase price shall be increased by five percent. The ESA Put Option and the ESA Call Option must be made within three months after the audited financial statements of ESA have been completed. On June 17, 2016, the three remaining minority shareholders exercised their ESA Put Options claim a value of BRL 8,656,000 (approximately $2,670,000 at March 31, 2017). At that time, the Company accrued the liability in other current liabilities and as an adjustment to additional paid in capital. The amount is subject to negotiation and any difference will be recorded upon completion of the transaction. See Note 5. Other The Company has identified a potential tax liability related to certain foreign subsidiaries’ failure to comply with laws and regulations of the jurisdictions, outside of their home country, in which their employees provided services. The Company has estimated the potential liability to be approximately $2,545,000 of which approximately $410,000 has been included in discontinued operations in the consolidated statement of operations for the three months ended March 31, 2017. The potential liability balance is included in other liabilities in the consolidated balance sheet at March 31, 2017. In connection with the move of its corporate headquarters, the Commonwealth of Pennsylvania provided the Company with a $1,000,000 grant received on July 13, 2015. The terms of the grant require the Company to spend at least $6,425,000 on capital expenditures for leasehold improvements and equipment for its new headquarters, remain at One Commerce Square for at least seven years and employ at least 359 persons no later than April 1, 2018. The Company has met the capital expenditure requirement and has a twelve year lease for its corporate headquarters. Upon receipt of the funds, the Company recorded a deferred credit which, assuming the employment requirement is met, will be reflected in income in the second quarter of 2018. If the Company does not meet the employment criteria, it will be required to repay the grant to the Commonwealth of Pennsylvania. The landlord for the new Philadelphia headquarters provided the Company with a tenant improvement allowance amounting to approximately $3,894,000. The tenant improvement allowance has been deferred, is included in other liabilities in the consolidated balance sheet at March 31, 2017 and December 31, 2016 and is being amortized on a straight-line basis against rent expense over the term of the twelve-year lease which commenced on May 1, 2015.

The estimated working capital adjustment was supported by a working capital escrow of $2.0 million in cash, funded by the Company at closing. Within sixty days after closing, a final net working capital will be determined and if the net working capital is greater than the estimated working capital as of closing (i) the purchasers shall pay the Company such excess amount and (ii) the working capital escrow amount shall be released together in its entirety. If the final net working capital is less than the estimated working capital, then the shortfall amount shall be paid by the escrow agent from the working capital escrow amount. If such shortfall is greater than the working capital escrow amount, then the Company shall pay the amount by which such shortfall amount exceeds the working capital escrow amount to the purchasers.in cash. In addition, the Company was required to provide a $3.75 million letter of credit into escrow in order to secure certain of the Company’s indemnification obligations for 12 months following closing. The funds provided by the sale of the Construction Claims Group and the cash received upon the draw down under the amended Revolving Credit Facilities (described below) were used as follows: (a) $117,000,000 to pay off the Term Loan Facility; (b) $25,000,000 to pay down the U.S. Revolver; (c) approximately $9,072,000 to pay down the International Revolver; and (d) approximately $1,214,000 to pay accrued interest and certain bank fees. Financing Transactions Simultaneously with the closing of the sale, the Company terminated its Term Loan Facility, amended its U.S. Revolver to reduce the amount available to the Company from $30,000,000 to $25,000,000, amended its International Revolver to reduce the amount available to the Company from $15,000,000 to $10,000,000, and drew approximately $25,191,000 in cash and approximately $9,193,000 in letters of credit against the new Revolving Credit Facilities. Deferred fees incurred with establishing the Secured Credit Facilities amounting to approximately $5,622,000 will be charged to discontinued operations in the quarter ending June 30, 2017. The U.S. Revolver and the International Revolver each have a term of five years from the closing and provide for letter of credit sub-limits in amounts of $20,000,000 and $8,000,000, respectively. The maximum Consolidated Net Leverage Ratio will be increased from the prior credit facilities to 3.00 for all test dates and will not decline. The definition of Consolidated Net Leverage Ratio was amended to (i) remove the cap on the amount of permitted cash netting and (ii) permit netting of unrestricted cash and cash equivalents. The Company incurred fees totaling $1,625,000 which will be deferred and amortized to interest expense over the five year term of the facilities. As of the date of closing, the new facilities are substantially drawn. We intend to pursue additional borrowing options to improve our liquidity. Resignation of Chief Executive Officer Effective as of May 3, 2017, David L. Richter, the Company’s Chief Executive Officer and a member of the Company’s Board of Directors, tendered his resignation from all positions with the Company.
