Summary of Significant Accounting Policies

Note 2—Summary of Significant Accounting Policies

(a) Basis of Presentation

The accompanying consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States. The consolidated financial statements include the accounts of Hill International, Inc. and its majority owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

(b) Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States 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 revenue and expenses during the reporting period. Actual results could differ from those estimates. The estimates affecting the consolidated financial statements that are particularly significant include revenue recognition, allocation of purchase price to acquired intangibles and goodwill, recoverability of long-lived assets, income taxes, allowance for doubtful accounts and commitments and contingencies.

Assets and liabilities of all foreign operations are translated at year-end rates of exchange, and the statements of operations are translated at the average rates of exchange for the year. Gains or losses resulting from translating foreign currency financial statements are accumulated in a separate component of stockholders' equity entitled accumulated other comprehensive loss until the entity is sold or substantially liquidated. Gains or losses from foreign currency transactions (transactions denominated in a currency other than the entity's local currency) are reflected in selling, general, and administrative expenses in the consolidated statement of operations.

(d) Fair Value of Financial Instruments

The fair value of financial instruments, which primarily consists of cash and cash equivalents, accounts receivable, accounts payable and due to bank, approximates carrying value due to the short-term nature of the instruments. The carrying value of our various credit facilities approximates fair value as the interest rate is variable. The term loan approximates fair value as the Company recently entered into that agreement.

(e) Cash and Cash Equivalents

Cash and cash equivalents include cash on hand and investments in money market funds and investment grade securities held with high quality financial institutions. The Company considers all highly liquid instruments purchased with a remaining maturity of three months or less at the time of purchase to be cash equivalents.

(f) Restricted Cash

Restricted cash represents cash collateral required to be maintained in foreign bank accounts to serve as collateral for letters of credit, bonds or guarantees on several projects. The cash will remain restricted until the respective project has been completed, which typically is greater than one year.

(g) Concentrations of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash investments and accounts receivable.

The Company maintains its cash accounts with high quality financial institutions. Although the Company currently believes that the financial institutions, with which it does business, will be able to fulfill their commitments to it, there is no assurance that those institutions will be able to continue to do so.

The Company provides professional services, under contractual arrangements, to domestic and foreign governmental units, institutions and the private sector. To reduce credit risk, the Company performs ongoing credit evaluations of its clients and does not require collateral beyond customary retainers.

At December 31, 2013, the accounts receivable related to the work performed prior to March 2011 under contracts in Libya, amounted to approximately $57,000,000. The Company believes that the amounts due will be collected, however, if future events preclude us from doing so, there could be a significant adverse impact on the Company's consolidated results of operations and consolidated financial position.

The following tables show the number of the Company's clients which contributed 10% or more of revenue and accounts receivable, respectively:

(h) Allowance for Doubtful Accounts

The allowance for doubtful accounts is an estimate prepared by management based on identification of the collectibility of specific accounts and the overall condition of the receivable portfolios. When evaluating the adequacy of the allowance for doubtful accounts, the Company specifically analyzes trade receivables, including retainage receivable, historical bad debts, client credits, client concentrations, client credit worthiness, current economic trends and changes in client payment terms. If the financial condition of clients were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. Likewise, should the Company determine that it would be able to realize more of its receivables in the future than previously estimated, an adjustment to the allowance would increase earnings in the period such determination was made. The allowance for doubtful accounts is reviewed on a quarterly basis and adjustments are recorded as deemed necessary.

(i) Property and Equipment

Property and equipment is stated at cost, less accumulated depreciation and amortization. Depreciation and amortization is provided over the estimated useful lives of the assets as follows:

Method

Estimated Useful Life

Furniture and equipment

Straight-line

10 years

Leasehold improvements

Computer equipment and software

Straight-line

3 to 5 years

Automobiles

Straight-line

5 years

The Company capitalizes costs associated with internally developed and/or purchased software systems that have reached the application development stage and meet recoverability tests. Capitalized costs include external direct costs of materials and services utilized in developing or obtaining internal-use software, payroll and payroll-related expenses for employees who are directly associated with and devote time to the internal-use software project. Capitalization of such costs begins when the preliminary project stage is complete and ceases no later than the point at which the project is substantially complete and ready for its intended purpose. Costs for general and administrative, overhead, maintenance and training, as well as the cost of software that does not add functionality to existing systems, are expensed as incurred.

Upon retirement or other disposition of these assets, the cost and related depreciation are removed from the accounts and the resulting gain or loss, if any, is reflected in results of operations. Expenditures for maintenance, repairs and renewals of minor items are charged to expense as incurred. Major renewals and improvements are capitalized.

(j) Retainage Receivable

Retainage receivable represents balances billed but not paid by clients pursuant to retainage provisions in the construction management contracts and will be due upon completion of specific tasks or the completion of the contract. The current portion of retainage receivable is included in accounts receivable and the long-term portion of retainage receivable is included in retainage receivable in the consolidated balance sheets.

(k) Long-Lived Assets

Acquired intangible assets consist of contract rights, client related intangibles and trade names arising from the Company's acquisitions. Contract rights represent the fair value of contracts in progress and backlog of an acquired entity. For intangible assets purchased in a business combination, the estimated fair values of the assets are used to establish the cost bases. Valuation techniques consistent with the market approach, the income approach and the cost approach are used to measure fair value. These assets are amortized over their estimated lives which range from three to fifteen years.

The Company reviews long-lived assets to be held-and-used for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. If the sum of the undiscounted expected future cash flows over the remaining useful life of a long-lived asset is less than its carrying amount, the asset is considered to be impaired. Impairment losses are measured as the amount by which the carrying amount of the asset exceeds the fair value of the asset. When fair values are not available, the Company estimates fair value using the expected future cash flow discounted at a rate commensurate with the risks associated with the recovery of the asset. Assets to be disposed of are reported at the lower of carrying amount or fair value less costs to sell.

(l) Goodwill

Goodwill represents the excess of purchase price and other related costs over the value assigned to the net tangible and identifiable intangible assets of businesses acquired. Acquired intangible assets other than goodwill are amortized over their useful lives. For intangible assets purchased in a business combination, the estimated fair values of the assets are used to establish the cost bases. Valuation techniques consistent with the market approach, the income approach and the cost approach are used to measure fair value.

Goodwill is tested annually for impairment in its fiscal third quarter. The Company has determined that it has two reporting units, the Project Management unit and the Construction Claims unit. The Company made that determination based on the similarity of the services provided, the methodologies in delivering our services and the similarity of the client base in each of these units. Goodwill is assessed for impairment using a two-step approach. In the first step of the impairment test, the Company compares the fair value of the reporting unit in which the goodwill resides to its carrying value. To the extent the carrying amount of a reporting unit exceeds its fair value, an indication exists that the reporting unit's goodwill may be impaired and the Company must perform a second more detailed assessment. The second step, if necessary, involves allocating the reporting unit's fair value to all of its recognized and unrecognized assets and liabilities in order to determine the implied fair value of the reporting unit's goodwill as of the assessment date. The implied fair value of the reporting unit's goodwill is then compared to the carrying amount of goodwill to quantify an impairment charge as of the assessment date.

Application of the goodwill impairment test requires significant judgments including estimation of future cash flows, which is dependent on internal forecasts, estimation of the long-term rate of growth for the businesses, the useful life over which cash flows will occur, and determination of the Company's weighted average cost of capital. The Company's changes in estimates and assumptions could materially affect the determination of fair value and/or conclusions on goodwill impairment for each reporting unit. The Company performed its annual impairment test effective July 1, 2013 and noted no impairment for either of its reporting units. In the future, the Company will continue to perform the annual test during its fiscal third quarter unless events or circumstances indicate an impairment may have occurred before that time.

(m) Investments

Hill International (Spain), S.A.

The Company's subsidiary, Hill International (Spain), S.A. ("Hill Spain"), has the following cost-basis investments:

•

Concessia, Cartera y Gestion de Infrastructuras, S.A. ("Concessia")—Hill Spain has made payments totaling $4,239,000 towards an initial 5.16% interest in this entity which invests in the equity of companies which finance, construct and operate various public and private infrastructure projects. The payments represented approximately 66% of Hill Spain's total required capital contribution. Hill Spain had accrued the remaining commitment of approximately $2,120,000 and had included that amount in the cost of the investment and in other liabilities in the accompanying consolidated balance sheet at December 31, 2012. During 2013, the aggregate capitalization of Concessia was reduced from approximately €93,000,000 to approximately €71,000,000. At that time, Hill Spain chose to reduce its total investment to a 4.45% interest and to distribute the excess 0.71% interest to the other shareholders of Concessia. Hill Spain has reduced both the cost of the investment and other liabilities by $2,120,000.

•

Nuevo Hospital de Burgos, S.A.—Hill Spain paid $3,761,000 for a 5.18% interest in this entity which, on completion of construction, will operate a new hospital in Burgos, Spain. On January 12, 2012 Hill Spain signed an agreement to sell its entire holding to its affiliate Concessia which is subject to the approval of the local authority, the owner of the facility and the financial institutions involved in the project. Hill Spain received a down payment of $3,149,000 and has accrued a receivable for $612,000. Although the final price is subject to certain conditions, the Company expects the investment to be fully recovered.

Other

The Company will, in the ordinary course, form joint ventures for specific projects. These joint ventures typically require limited or no investment and simply provide a pass-through for the Company's billings. Any distributions in excess of the Company's billings are accounted for as income when received.

(n) Due to Bank

Under the Company's cash-management system, certain cash accounts reflect credit balances to the extent checks were disbursed but not immediately funded at the bank. The Company manages this process daily and ensures all checks are funded when presented.

(o) Deferred Revenue

In certain instances the Company may collect advance payments from clients for future services. Upon receipt, the payments are reflected as deferred revenue in the Company's consolidated balance sheets. As the services are performed, the Company reduces the balance and recognizes revenue.

(p) Deferred Rent

Rent expenses for operating leases which include scheduled rent increases is determined by expensing the total amount of rent due over the life of the operating lease on a straight-line basis. The difference between the rent paid under the terms of the lease and the rent expensed on a straight-line basis is recorded as a liability. The deferred rent at December 31, 2013 and 2012 was $3,043,000 and $2,792,000, respectively, and is included in other liabilities in the consolidated balance sheet.

(q) Income Taxes

The Company estimates income taxes in each of the jurisdictions in which it operates. This process involves estimating its actual current tax exposure together with assessing temporary differences resulting from differing treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included within the Company's consolidated balance sheets. The Company assesses the likelihood that the deferred tax assets will be recovered from future taxable income and to the extent it believes recovery is not likely, the Company establishes a valuation allowance. To the extent the Company establishes a valuation allowance in a period, it must include an expense within the tax provision in the consolidated statements of earnings. The Company has recorded a valuation allowance to reduce the deferred tax asset to an amount that is more likely to be realized in future years. If the Company determines in the future that it is more likely that the deferred tax assets subject to the valuation allowance will be realized, then the previously provided valuation allowance will be adjusted.

The Company recognizes a tax benefit in the financial statements for an uncertain tax position only if management's assessment is that the position is "more likely than not" (i.e., a likelihood greater than 50 percent) to be allowed by the tax jurisdiction based solely on the technical merits of the position. The term "tax position" refers to a position in a previously filed tax return or a position expected to be taken in a future tax return that is reflected in measuring current or deferred income tax assets and liabilities for interim or annual periods.

(r) Revenue Recognition

The Company generates revenue primarily from providing professional services to its clients. Revenue is generally recognized upon the performance of services. In providing these services, the Company may incur reimbursable expenses, which consist principally of amounts paid to subcontractors and other third parties and travel and other job related expenses that are contractually reimbursable from clients. The Company has determined that it will include reimbursable expenses in computing and reporting its total revenue as long as the Company remains responsible to the client for the fulfillment of the contract and for the overall acceptability of all services provided.

The Company earns its revenue from time-and-materials, cost-plus and fixed-price contracts. If estimated total costs on any contract indicate a loss, the Company charges the entire estimated loss to operations in the period the loss becomes known. The cumulative effect of revisions to revenue, estimated costs to complete contracts, including penalties, incentive awards, change orders, claims, anticipated losses, and others are recorded in the accounting period in which the events indicating a loss are known and the loss can be reasonably estimated. Such revisions could occur at any time and the effects may be material.

Time-and-Materials Contracts

Under its time-and-materials contracts, the Company negotiates hourly billing rates and charges its clients based on the actual time that the Company spends on a project. In addition, clients reimburse the Company for its actual out-of-pocket costs of materials and other direct incidental expenditures that the Company incurs in connection with its performance under the contract. Its profit margins on time-and-materials contracts fluctuate based on actual labor and overhead costs that the Company directly charges or allocates to contracts compared with negotiated billing rates. Revenue on these contracts are recognized based on the actual number of hours the Company spends on the projects plus any actual out-of-pocket costs of materials and other direct incidental expenditures that the Company incurs on the projects. Its time-and-materials contracts generally include annual billing rate adjustment provisions.

Cost-Plus Contracts

The Company has two major types of cost-plus contracts:

Cost-Plus Fixed Fee

Under cost-plus fixed fee contracts, the Company charges its clients for its costs, including both direct and indirect costs, plus a fixed negotiated fee. In negotiating a cost-plus fixed fee contract, the Company estimates all recoverable direct and indirect costs and then adds a fixed profit component. The total estimated cost plus the negotiated fee represents the total contract value. The Company recognizes revenue based on the actual labor costs, based on hours of labor effort, plus non-labor costs the Company incurs, plus the portion of the fixed fee the Company has earned to date. The Company invoices for its services as revenue is recognized or in accordance with agreed-upon billing schedules. Aggregate revenue from cost-plus fixed fee contracts may vary based on the actual number of labor hours worked and other actual contract costs incurred. However, if actual labor hours and other contract costs exceed the original estimate agreed to by its client, the Company generally must obtain a change order, contract modification, or successfully prevail in a claim in order to receive additional revenue relating to the additional costs (see "Change Orders and Claims").

Cost-Plus Fixed Rate

Under its cost-plus fixed rate contracts, the Company charges clients for its costs plus negotiated rates based on its indirect costs. In negotiating a cost-plus fixed rate contract, the Company estimates all recoverable direct and indirect costs and then adds a profit component, which is a percentage of total recoverable costs to arrive at a total dollar estimate for the project. The Company recognizes revenue based on the actual total number of labor hours and other costs the Company expends at the cost plus the fixed rate the Company negotiated. Similar to cost-plus fixed fee contracts, aggregate revenue from cost-plus fixed rate contracts may vary and the Company generally must obtain a change order, contract modification, or successfully prevail in a claim in order to receive additional revenue relating to any additional costs that exceed the original contract estimate (see "Change Orders and Claims").

Labor costs and subcontractor services are the principal components of its direct costs on cost-plus contracts, although some include materials and other direct costs. Some of these contracts include a provision that the total actual costs plus the fee will not exceed a guaranteed price negotiated with the client. Others include rate ceilings that limit the reimbursement for general and administrative costs, overhead costs and materials handling costs. The accounting for these contracts appropriately reflects such guaranteed price or rate ceilings.

Firm Fixed-Price ("FFP") Contracts

The Company's FFP contracts have historically accounted for most of its fixed-price contracts. Under FFP contracts, the Company's clients pay an agreed amount negotiated in advance for a specified scope of work. The Company recognizes revenue on FFP contracts using the percentage-of-completion method (recognizing revenue as costs are incurred). Profit margins the Company recognizes in all periods prior to completion of the project on any FFP contract depend on the accuracy of the Company's estimates of approximate revenue and expenses and will increase to the extent that its current estimates of aggregate actual costs are below amounts previously estimated. Conversely, if the Company's current estimated costs exceed prior estimates, its profit margins will decrease and the Company may realize a loss on a project. In order to increase aggregate revenue on the contract, the Company generally must obtain a change order, contract modification, or successfully prevail in a claim in order to receive payment for the additional costs (see "Change Orders and Claims").

Change Orders and Claims

Change orders are modifications of an original contract that effectively change the provisions of the contract without adding new provisions. Either the Company or its client may initiate change orders. They may include changes in specifications or design, manner of performance, facilities, equipment, materials, sites and period of completion of the work. Claims are amounts in excess of the agreed contract price that the Company seeks to collect from its clients or others for client-caused delays, errors in specifications and designs, contract terminations, change orders that are either in dispute or are unapproved as to both scope and price, or other causes of unanticipated additional contract costs.

Change orders and claims occur when changes are experienced once contract performance is underway. Change orders are sometimes documented and terms of such change orders are agreed with the client before the work is performed. Sometimes circumstances require that work progresses before agreement is reached with the client. Costs related to change orders and claims are recognized when they are incurred. Change orders and claims are included in total estimated contract revenue when it is probable that the change order or claim will result in a bona fide addition to contract value that can be reliably estimated. No profit is recognized on claims until final settlement occurs; unapproved change orders are evaluated as claims. This can lead to a situation where costs are recognized in one period and revenue is recognized when client agreement is obtained or claims resolution occurs, which can be in subsequent periods.

The Company has contracts with the U.S. government that contain provisions requiring compliance with the U.S. Federal Acquisition Regulations ("FAR"). These regulations are generally applicable to all of its federal government contracts and are partially or fully incorporated in many local and state agency contracts. They limit the recovery of certain specified indirect costs on contracts subject to the FAR. Cost-plus contracts covered by the FAR provide for upward or downward adjustments if actual recoverable costs differ from the estimate billed under forward pricing arrangements. Most of its federal government contracts are subject to termination at the convenience of the client. Contracts typically provide for reimbursement of costs incurred and payment of fees earned through the date of such termination.

Federal government contracts which are subject to the FAR and some state and local governmental agencies require audits, which are performed for the most part by the Defense Contract Audit Agency ("DCAA"). The DCAA audits the Company's overhead rates, cost proposals, incurred government contract costs, and internal control systems. During the course of its audits, the DCAA may question incurred costs if it believes the Company has accounted for such costs in a manner inconsistent with the requirements of the FAR or Cost Accounting Standards and recommend that its U.S. government corporate administrative contracting officer disallow such costs. Historically, the Company has not experienced significant disallowed costs as a result of such audits. However, the Company can provide no assurance that the DCAA audits will not result in material disallowances of incurred costs in the future.

(s) Share-Based Compensation

The Company uses the Black-Scholes option pricing model to measure the estimated fair value of options to purchase the Company's common stock. The compensation expense, less estimated forfeitures, is being recognized over the service period on a straight-line basis. The Company's policy is to use newly issued shares to satisfy the exercise of stock options.

(t) Advertising Costs

Advertising costs are expensed as incurred and amounted to the following (in thousands):

(u) Earnings per Share

Basic earnings per common share has been computed using the weighted-average number of shares of common stock outstanding during the year. Diluted earnings per common share incorporates the incremental shares issuable upon the assumed exercise of stock options using the treasury stock method.

Dilutive stock options increased average common shares outstanding by approximately 225,000 shares for the year ended December 31, 2013. For the years ended December 31, 2012 and 2011, stock options were anti-dilutive.

Options to purchase 5,364,000 shares, 4,492,000 shares and 2,385,000 shares of the Company's common stock were not included in the calculation of common shares outstanding for the years ended December 31, 2013, 2012 and 2011, respectively, because they were anti-dilutive.

(v) Recent Accounting Pronouncements

In February 2013, the FASB issued ASU No. 2013-2, which amends the Comprehensive Income Topic of the ASC. The ASU requires companies to report either on the income statement or disclose in the footnotes to the financial statement the effects on earnings from items that are reclassified out of the category of shareholder equity called accumulated other comprehensive income. The adjustments will consist of amounts from the fiscal period covered by the financial statements. Companies will also have to make cross references to other disclosures required in U.S. GAAP for other line items used to adjust earnings. The FASB wants this requirement applied to amounts that are initially transferred to another balance sheet item before being entered as an adjustment to earnings. The Company adopted the ASU on January 1, 2013. The ASU did not affect the Company's consolidated results of operations, financial condition or liquidity.

	Our recent acquisition activity is detailed below. The Company's consolidated financial statements include the operating results of these businesses from their respective dates of acquisition. Pro forma results of operations for these acquisitions have not been presented because they are not material to the Company's consolidated results of operations, either individually or in the aggregate.

	The Company expenses all acquisition-related costs plus any anticipated restructuring costs for which it is not obligated at the acquisition date, rather than including such costs as a component of the purchase consideration. During 2013, 2012 and 2011, the Company expensed $455,000, $84,000 and $164,000, respectively, of acquisition-related costs.

	Collaborative Partners, Inc.

	On December 23, 2013, Hill acquired all of the outstanding common stock of Collaborative Partners, Inc. ("CPI"), a firm that provides project management, strategic planning and regulatory services for healthcare, life sciences, educational, commercial and residential construction projects throughout New England. CPI, which has 20 professionals, has offices in Boston, Massachusetts and Providence, Rhode Island. The acquisition expands the Company's project management business in the New England region of the United States. At closing, the sellers received $2,450,000 in the form of 678,670 shares of the Company's common stock priced at $3.61 per share. On March 7, 2014, the sellers received 171,308 shares of common stock with a value of $618,000 representing CPI's common equity in excess of $600,000. On December 23, 2014, the sellers will receive, subject to potential offset, an additional $350,000 in shares of common stock; the number of shares will be determined based on the average closing price of the common stock for the ten trading days ending on December 18, 2014. The Agreement also provides that (1) should the price of the Company's common stock not increase by 50% to $5.42 on December 23, 2014, the Company will issue additional shares to the sellers representing the difference between $5.42 and the price on December 23, 2014, and (2) the sellers are entitled to receive additional shares of the Company's common stock for (i) 50% of the operating profit of CPI in excess of $1,000,000 for the first 12-month period after closing, but in no event more than $500,000, and (ii) 5% of the net revenue backlog in excess of $10,000,000 on the date 60 days after closing. The Company has estimated and accrued $2,697,000 for the potential additional consideration which is included in other current liabilities in the consolidated balance sheet at December 31, 2013. The portion of the liability attributable to the change in the common stock price will be remeasured at each reporting date and any change in the liability will be reflected in the consolidated statement of operations. The Company acquired intangible assets and goodwill amounting to $1,516,000 and $3,049,000, respectively. The acquired intangible assets have a weighted average life of 5.3 years. The acquired intangible assets consist of a client relationship intangible of $509,000 with a ten-year life and a contract intangible of $1,007,000 with a three-year life. Goodwill, which is not deductible for income tax purposes, has been allocated to the Project Management operating segment.

	Binnington Copeland & Associates (Pty.) Ltd.

	On May 30, 2013, Hill International N.V., the Company's wholly-owned subsidiary, acquired all of the outstanding common stock of Binnington Copeland & Associates (Pty.) Ltd. and BCA Training (Pty.) Ltd. (together "BCA"). BCA, with 34 professionals, has offices in Johannesburg and Cape Town, South Africa. The acquisition provides the Company's claims business access to Africa's large infrastructure and mining projects and allows for expansion into the rest of sub-Saharan Africa. Consideration consisted of $2,000,000 plus a potential earn-out, both payable in shares of the Company's common stock. The purchase price is payable as follows: $1,072,400 (the "Closing Date Payment") on the closing date, $927,600 (the "Second Tranche Payment") on July 31, 2013 and an earn-out (the "Third Tranche Payment") to be determined in the third quarter of 2014. The Company issued 379,655 shares of its common stock in satisfaction of the Closing Date Payment; the number of shares was determined by dividing the Closing Date Payment by the average closing price of our common stock for the thirty trading days ending on May 17, 2013. On July 31, 2013, the Company issued 331,444 shares of its common stock in satisfaction of the Second Tranche Payment. The number of shares was determined by dividing the Second Tranche Payment by the average closing price of our common stock for the thirty trading days ending on July 19, 2013. The shares issuable in satisfaction of the Third Tranche Payment will be determined by dividing the Third Tranche Payment by the average closing price of our common stock for the thirty trading days ending on July 21, 2014. The actual amount of the Third Tranche Payment will be determined by comparing the average net profit before taxes for the two-year periods ending July 31, 2014 to the net profit before taxes for the year ended July 31, 2012, and multiplying the excess, if any, by 2.205. The Third Tranche Payment is estimated to be approximately $902,000. The Company reflected the liability for the Third Tranche Payment in other current liabilities in the consolidated balance sheet at December 31, 2013. The Company acquired intangible assets and goodwill amounting to 13,143,000 South African Rand (ZAR) (approximately $1,312,000 on the acquisition date) and ZAR 12,873,000 ($1,285,000), respectively. The acquired intangible assets have a weighted average life of 8.2 years. The acquired intangible assets consist of a client relationship intangible of ZAR 10,546,000 ($1,053,000) with a ten-year life, a contract intangible of ZAR 1,863,000 ($186,000) with an 8-month life and a trade name intangible of ZAR 734,000 ($73,000) with a two-year life. Goodwill, which is not deductible for income tax purposes, has been allocated to the Construction Claims operating segment.

	Engineering S.A.

	On February 28, 2011, the Company's subsidiary, Hill Spain, indirectly acquired 60% of the outstanding common stock of Engineering S.A., one of the largest project management firms in Brazil with approximately 400 professionals. It has main offices in Rio de Janeiro and Sao Paulo and an additional office in Parauapebas. Engineering S.A. provides project management, construction management and engineering consulting services throughout Brazil. Total consideration will not exceed 42,000,000 Brazilian Reais ("BR") (approximately $25,336,000 at the date of acquisition) consisting of an initial cash payment of BR22,200,000 (approximately $13,392,000) plus minimum additional payments of BR7,400,000 (approximately $4,464,000) due on each of April 30, 2012 and 2013 and a potential additional payment of BR5,000,000 ($3,016,000). The Company acquired intangible assets and goodwill amounting to BR24,540,000 ($14,783,000) and BR46,339,000 ($27,987,000), respectively. The acquired intangible assets have a weighted average life of 7.7 years. The acquired intangible assets consist of a client relationship intangible of BR13,942,000 ($8,399,000) with a ten-year life, a contract intangible of BR8,385,000 ($5,051,000) with a two-year life and a trade name intangible of BR2,213,000 ($1,333,000) with a fifteen-year life. Goodwill, which is deductible for income tax purposes, has been allocated to the Project Management operating segment. Also, 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.

	The Company estimated the fair value of the potential additional payments to total approximately BR17,200,000 (approximately $10,376,000) and has discounted these amounts using an interest rate of 4.72%, the weighted average interest rate on the outstanding borrowings under the Company's Credit Agreement at the acquisition date. The Company paid the first installment amounting to 6,624,000 BRL (approximately $3,508,000 on April 30, 2012 and paid the second installment amounting to 11,372,000 BRL (approximately $5,095,000) on July 23, 2013.

	Gerens Management Group, S.A.

	On February 15, 2008, the Company's subsidiary, Hill International N.V. (formerly Hill International S.A.), acquired 60% of the outstanding capital stock of Gerens Management Group, S.A., whose name was subsequently changed to Hill International (Spain), S.A. ("Hill Spain"). In connection with the acquisition, Hill Spain's shareholders entered into an agreement whereby the minority shareholders have a right to compel ("Gerens Put Option") Hill International N.V. to purchase any or all of their shares during the period from March 31, 2010 to March 31, 2020. Hill International N.V. also has the right to compel the minority shareholders to sell any or all of their shares during the period from March 31, 2011 to March 31, 2021. The purchase price for such shares shall be the greater of (a) €18,000,000 ($23,808,000 as of December 31, 2012) increased by the General Price Index (capped at 3.5% per annum) or (b) ten times Hill Spain's earnings before interest and income taxes for the prior fiscal year, multiplied by a percentage which the shares to be purchased bear to the total number of shares outstanding at the time of purchase. Such amount may be adjusted for increases in equity subsequent to the acquisition date, and can be paid in cash or shares of our common stock at the option of the sellers.

	During late 2011 through late 2012, ten minority shareholders, who owned approximately 23.9% of the outstanding common stock of Hill Spain, exercised their Gerens Put Options. The Company accrued the liability of approximately €7,166,000 (approximately $9,477,000) which is included in other current liabilities in the consolidated balance sheet at December 31, 2012. The balance includes interest of approximately €115,000 (approximately $152,000) which has been charged to interest expense in the consolidated statement of operations for the year ended December 31, 2012. The aggregate consideration plus interest was paid on January 3, 2013. In connection with the transactions, the Company reduced noncontrolling interests by €2,717,000 (approximately $3,594,000), increased goodwill by €1,300,000 (approximately $1,720,000) and increased intangible assets by €4,334,000 (approximately $5,580,000) during 2012.

	During 2013, the remaining minority shareholders, who owned approximately 6.8% of the outstanding common stock of Hill Spain, exercised their Gerens Put Options. The Company now owns 100% of Hill Spain. The aggregate consideration plus interest was paid on December 4, 2013 in the amount of €2,031,000 (approximately $2,793,000). The balance includes interest of approximately €42,000 (approximately $56,000). In connection with the transactions, the Company reduced noncontrolling interests by €828,000 (approximately $1,094,000), increased goodwill by €348,000 (approximately $460,000) and increased intangible assets by approximately €1,161,000 (approximately $1,534,000).

The reduction consisted of a cash payment by the Libyan Organization for the Development of Administrative Centres ("ODAC") of approximately 3,000,000 Libyan dinars ("LYD") ($2,400,000) that was made directly to Hill and a cash payment of approximately LYD 800,000 ($700,000) that was made by ODAC to Libyan tax authorities on Hill's behalf. The LYD 3,000,000 cash payment made directly to Hill is not freely convertible into other currencies. As a result, this cash remains in Hill's Libyan bank account. At December 31, 2013, the remaining accounts receivable outstanding related to Hill's work in Libya amounted to approximately $57,000,000.

	During February 2014, the Company received additional payments of approximately $6,100,000 consisting of approximately 200,000 pounds sterling ($300,000), approximately LYD 2,100,000 ($1,700,000) and $4,100,000 in U.S. dollars.

	Since the end of the Libyan civil unrest in October 2011, the Company has sought to recover its receivable from ODAC through ongoing negotiations rather than pursue its legal rights for payment under the contracts. The Company believes that this course of action provides the best likelihood for recovery as it could result in completion of and payment on the existing contracts as well as the potential for the award of new contracts. There is at present no agreement, understanding or timetable for further payments of Hill's accounts receivable from ODAC or a return to work on Hill's existing contracts. However, management believes that these payments, along with letters of credit of approximately $14,000,000 posted in our favor by ODAC, were made in good faith and are a positive indication that ODAC intends to satisfy its obligations to Hill. However, the Company cannot predict with certainty when, or if, the remaining accounts receivable will be paid by the Libyan authorities or when work will resume there. In the event that the Company does not realize any further payments, there could be a significant adverse impact on its consolidated results of operations and consolidated financial position.

Revolving Credit Agreement

The Company entered into a Credit Agreement, dated June 30, 2009, (the "Credit Agreement"), with Bank of America, N.A., Capital One, N.A., The PrivateBank and Trust Company, PNC Bank N.A. (the "Lenders"), and Bank of America, N.A., as Administrative Agent (the "Agent").

During 2011 and through the first quarter of 2012, the Company was in violation of certain financial covenants and subsequently entered into a series of waivers, forbearance agreements and amendments to the Credit Agreement. During the first quarter of 2012, the Company entered into a second amendment to the Credit Agreement (the "Second Amendment"), dated March 6, 2012 with the Agent and Lenders. The Company incurred fees related to the Second Amendment amounting to approximately $2,075,000 which were charged to interest expense and related financing fees, net.

During the second quarter of 2012, the Company was in violation, under the Second Amendment, of certain financial covenants and the covenant regarding restricted payments due to the payment of dividends by certain of the Company's subsidiaries to their noncontrolling interest parties.

On October 18, 2012, the Company entered into a Third Amendment to Credit Agreement (the "Third Amendment"), pursuant to which the Agent and the Lenders agreed to waive the defaults noted above and the parties thereto, agreed, among other things, as follows:

•

Maximum amounts outstanding under the Credit Agreement, including amounts under the letter of credit sub-facility, are reduced from $100,000,000 to $65,000,000;

•

The letter of credit sub-facility is increased from $35,000,000 to $45,000,000;

•

The maturity date is extended to March 31, 2015; however, no Letter of Credit may be issued with an expiration date after March 31, 2016 without approval by all Lenders;

•

The interest rates for loans, fees for Letters of Credit and unused facility fees are as follows:

•

Eurodollar Rate loans (for interest periods of one, two, three or six months, as selected by the Company) will bear interest at a rate per annum equal to the British Bankers Association LIBOR Rate, plus an applicable rate between 2.50% and 7.00% depending on the Company's consolidated leverage ratio at the time of the borrowing;

•

Base Rate loans will bear interest at fluctuating rates per annum equal to sum of (a) the highest of (i) the Federal Funds Rate plus a rate of 0.50%, (ii) the rate of interest in effect for such day as publicly announced from time to time by Bank of America, N.A. as its "prime rate" and (iii) the Eurodollar Rate plus 1.00%, plus (b) an Applicable Rate between 1.10% and 5.50% depending on the Company's consolidated leverage ratio at the time of the borrowing;

•

Letter of Credit fees will accrue on each Letter of Credit issued under the Credit Agreement, based on the amount available for draw thereunder, at an Applicable Rate per annum which may vary between 2.50% and 7.00% depending on the Company's consolidated leverage ratio at the time of issuance; and

•

Unused facility commitment fees will accrue at a rate per annum which may vary between 0.25% and 0.50% depending on the Company's consolidated leverage ratio from time to time;

•

From the date of the Third Amendment, the Applicable Rate for Eurodollar Rate loans, Base Rate loans and Letters of Credit will be increased by 1.00% per annum—such interest will be added to the principal balance and capitalized on March 31, 2014 and thereafter payable in cash or waived in the event that prior to March 31, 2014 the Company has paid in full all obligations under the Credit Agreement (other than certain contingent obligations) and all commitments have been terminated under the Credit Agreement;

•

From and after April 1, 2014, the Applicable Rate for Eurodollar Rate loans, Base Rate loans and Letters of Credit will be increased by 2.00% per annum; and

•

During any fiscal quarter, if the total amount outstanding of certain cash investments made by the Company or any domestic subsidiaries to any foreign subsidiaries as of the last day of the prior fiscal quarter (net of repayments of such investments) exceeds (i) $6,000,000, the Applicable Rate for Eurodollar Rate loans, Base Rate loans and Letters of Credit will be increased by 1.00% per annum, and (ii) $12,000,000, the applicable rate for Eurodollar Rate loans, Base Rate loans and Letters of Credit will be increased by an additional 1.00% per annum.

The Company is required to comply with a consolidated leverage ratio, a consolidated fixed charge ratio and a senior leverage ratio.

•

Consolidated leverage ratio is the ratio of consolidated funded indebtedness to consolidated EBITDA for the most recently completed measurement period.

•

Consolidated fixed charge coverage ratio is the ratio of (a) consolidated EBITDA, plus rental expense less the sum of (A) the aggregate amount of federal, state, local and foreign income taxes paid in cash (other than taxes paid as a result of the receipt of the Libya Receivable) and (B) the aggregate amount of all dividends and distributions paid in cash by the Company to its shareholders to (b) the sum of consolidated interest charges, rental expense, payments on long-term debt and the principal component of capital leases during the most recently completed measurement period and (iv) any earn-out payments required to be paid in cash for the most recently completed measurement period.

•

Senior leverage ratio is the ratio of (i) consolidated funded indebtedness minus certain subordinated indebtedness and the par amount of the term loan to (ii) consolidated EBITDA.

Consolidated funded indebtedness is the sum of the outstanding principal amount of all obligations for borrowed money, the par value of the term loan, all direct obligations arising under letters of credit under the Credit Agreement, all obligations evidenced by bonds, debentures, notes, loan agreements, capital leases and guarantees of indebtedness of persons other than the Company or its subsidiaries.

Consolidated EBITDA is an amount equal to consolidated net income for the most recently completed four fiscal quarters plus (a) the following to the extent deducted in calculating such consolidated net income: consolidated interest charges, the provision for federal, state, local and foreign income taxes payable, depreciation and amortization expense, non-cash charges and (v) any deductions attributable to minority interests of third parties in non-wholly owned subsidiaries, except to the extent of cash dividends declared or paid to such minority interests minus (b) the following to the extent included in calculating such consolidated net income: federal, state, local and foreign income tax credits, all gains from investments recorded using the equity method, except to the extent of cash dividends or distributions received by the Company in respect of such investments and all non-cash items increasing consolidated net income for the most recently completed measurement period.

The following tables set forth the requirements for the consolidated leverage ratio, consolidated fixed charge ratio and the senior leverage ratio.

The Third Amendment also contains other covenants and certain restrictions relating to limitations on the ability of the Company or its subsidiaries to incur additional indebtedness, on the ability of the Company or its subsidiaries to make investments (including restrictions on the ability of the Company and its domestic subsidiaries to make loans to or investments in the Company's foreign subsidiaries) and acquisitions, on the ability of the Company to accumulate cash, declare or pay cash dividends to its stockholders, and on the ability of the Company's subsidiaries to declare or pay certain cash dividends. At December 31, 2013, the Company was in compliance with all of the loan covenants.

In connection with the Third Amendment, the Company agreed to pay: (i) an amendment fee of 1.00% of the Lenders' aggregate commitments as of October 18, 2012, payable in two parts: 0.50%, or $325,000, on October 18, 2012 and 0.50%, or $325,000, on March 31, 2014, however the latter payment will be waived in the event that prior to March 31, 2014 the Company has paid in full all Obligations (as defined in the Credit Agreement) under the Credit Agreement (other than certain contingent obligations) and all commitments have been terminated under the Credit Agreement; (ii) deferred fees of $1,215,000; (iii) an arrangement fee of $100,000; and (iv) accrued default interest of $1,059,000. The Company also paid approximately $1,150,000 to the Agent as reimbursement for its out-of-pocket costs incurred in connection with the Third Amendment. These costs amounting to approximately $4,174,000 in the aggregate were paid at closing and charged to interest expense and related financing fees, net.

On May 23, 2013 the Company entered into a Fourth Amendment to Credit Agreement pursuant to which, among other things, the lenders agreed to : (a) permit the Company to enter into an Agreement with Qatar National Bank for the issuance of letters of credit ("LCs") not to exceed $17,000,000, (b) increase the limit on LCs available to the Company's foreign subsidiaries who are not loan parties from $4,000,000 to $11,800,000 and (c) permit the Company to provide up to $20,000,000 as cash collateral for letters of credit and performance bonds. The Company paid an amendment fee of $150,000 to the Agent and reimbursed the Agent for its out-of-pocket cost amounting to approximately $372,000. These amounts are included in interest expense and related financing fees, net in the consolidated statements of operations for the year ended December 31, 2013.

At December 31, 2013, the Company had $17,207,000 in outstanding letters of credit. Due to conditions of the Credit Facility, as amended, total remaining availability was $8,793,000.

Term Loan Agreement

Simultaneously with its entry into the Third Amendment, the Company entered into a Term Loan Agreement dated as of October 18, 2012, among the Company, Special Value Opportunities Fund, LLC, Special Value Expansion Fund, LLC, Tennenbaum Opportunities Partners V, LP, Tennenbaum Opportunities Fund VI, LLC (the "Term Loan Lenders"), and Obsidian Agency Services, Inc. (the "Term Loan Agent"). The Term Loan Lenders made term loans (collectively, the "Term Loan") to the Company in the aggregate amount of $100,000,000 from which the Company received net proceeds of approximately $71,500,000 on October 18, 2012 (the "Closing Date"). The Term Loan was amended on May 23, 2013 (the "First Amendment"). The First Amendment contains identical provisions as those in the Fourth Amendment to the Credit Agreement. The proceeds of the Term Loan were used for the partial repayment of amounts outstanding under the Credit Agreement, and the payment of fees and expenses incurred in connection with the Term Loan Agreement and the Third Amendment. Obligations (as defined in the Term Loan Agreement) under the Term Loan Agreement are collateralized by a second lien (subject to the first/prior lien of the Agent under the Credit Agreement and to other Permitted Liens (as defined in the Term Loan Agreement)) on substantially all of the Company's assets, including, without limitation, accounts receivable, equipment, securities, financial assets and the proceeds of the foregoing, as well as by a pledge of 65% of the outstanding capital stock of our wholly-owned subsidiary, Hill International N.V. and of certain of our other foreign subsidiaries. The maturity date of the Term Loan is October 18, 2016.

Among other things, the Term Loan Agreement:

•

Limits the indebtedness which the Company and its subsidiaries may incur (including certain intercompany indebtedness, such as indebtedness from foreign subsidiaries to the Company);

•

Limits the investments, acquisitions and dividends which the Company and its subsidiaries may make (including investments by the Company in its foreign subsidiaries);

•

Limits the amount of cash the Company and its subsidiaries may accumulate;

•

Requires the Company to take certain actions, including providing monthly reporting to the Term Loan Lenders; and

•

Contains representations, warranties, affirmative and negative covenants and events of default which are substantially similar to those contained in the Credit Agreement (except in respect of financial covenants which are less restrictive than those under the Credit Agreement) and the other Loan Documents (as defined in the Credit Agreement).

At December 31, 2013, the Company was in compliance with all of the Term Loan covenants.

In connection with the Term Loan Agreement, the Company agreed, under certain conditions, to allow certain Term Loan Lenders to appoint two non-voting observers to the Company's board of directors.

The Company will pay interest on amounts outstanding from time to time under the Term Loan at a rate per annum equal to 7.50%; provided, however, such rate may be increased to 9.50% per annum if fixed price contracts (as defined under the Term Loan Agreement) or certain accounts receivable of the Company and its subsidiaries exceed percentages specified in the Term Loan Agreement.

Also, contemporaneous with its entry into the Term Loan Agreement, the Company entered into a Fee Letter. The Fee Letter requires the Company to pay to the Lenders an exit fee (the "Exit Fee"), which fee shall be earned in full on the Closing Date and due and payable on the date the Term Loan is paid in full (the "Exit Date"). "Exit Fee" means the amount, if any, when paid to the Term Loan Lenders on the Exit Date, that will result in the internal annual rate of return (the "IRR") to the Term Loan Lenders (the "IRR") on the Exit Date being equal to, but no greater than, 20%; provided, that in no event shall the Exit Fee Amount be less than $0 or greater than $11,790,000. The IRR is to be calculated as the rate of return earned by the Term Loan Lenders on their initial investment in the Term Loan (to be calculated as the principal amount of the Term Loan less the Closing Fee of $25,000,000) through the Exit Date taking into account the payment by the Company to the Term Loan Lenders of all principal, interest and other payments to the Term Loan Lenders pursuant to the Term Loan Agreement.

Additionally, the Company is required to make the following mandatory prepayments/payments and/or commitment reductions in respect of the Company's indebtedness under the Credit Agreement and under the Term Loan Agreement:

•

100% of the net proceeds received by the Company or any of its subsidiaries from certain sales of assets (subject to certain reinvestment rights), certain condemnation awards (subject to certain reinvestment rights) and insurance payments (subject to certain reinvestment rights) and from the issuance or incurrence of certain indebtedness with respect to borrowed monies of the Company ("Specified Proceeds"), and 50% of the net proceeds received by the Company or any of its subsidiaries from the issuance or sale of any equity interests in the Company (subject to certain exceptions), will be applied:

•

first, to satisfy the Minimum Liquidity Requirement (that is, unrestricted cash and cash equivalents plus availability under the Credit Agreement aggregating $30,000,000), and

•

second, up to 50% of the remaining net proceeds to repay the loans under the Credit Agreement and the remaining net proceeds to prepay the outstanding principal amount of the Term Loan; and

•

100% of the net proceeds received by the Company or any of its subsidiaries from any payment on the Net Libya Receivable (as defined in the Third Amendment) and any payments or distributions from the Company's majority-owned subsidiary HillStone International LLC will be applied:

•

first, to satisfy the Minimum Liquidity Requirement, and

•

second, 50% of the remaining net proceeds to repay the loans under the Credit Agreement and the other 50% to prepay the outstanding principal amount of the Term Loan.

•

All Excess Cash Flow (as defined in the Third Amendment) will be applied as follows:

•

if the consolidated leverage ratio as of the last day of the relevant fiscal year is 3.25 to 1.00 or greater,

•

first, to satisfy the Minimum Liquidity Requirement, and

•

second, 50% of the remaining Excess Cash Flow to repay the loans under the Credit Agreement and the other 50% to prepay the principal amount of the Term Loan; and

•

if the consolidated leverage ratio as of the last day of the relevant fiscal year is less than 3.25 to 1.00,

•

first, 50% of such Excess Cash Flow will be retained by the Company for working capital,

•

second, the remaining Excess Cash Flow to satisfy the Minimum Liquidity Requirement, and

•

third, 50% of the remaining Excess Cash Flow to repay the loans under the Credit Agreement and the other 50% to prepay the outstanding principal amount of the Term Loan.

•

If an Event of Default (as defined in the Credit Agreement) exists, each prepayment pursuant to the forgoing will not be applied to satisfy the Minimum Liquidity Requirement and will be applied as follows:

•

up to 50% of the remaining net proceeds or Excess Cash Flow, as applicable, first, to repay the loans under the Credit Agreement, and second, to cash collateralize outstanding Letters of Credit (and in the case of Specified Proceeds, but without regard to reinvestment rights otherwise available to the Company and/or its subsidiaries pursuant thereto, together with a concurrent permanent reduction to the commitment under the Credit Agreement equal to the sum of such repayment and cash collateral); and

•

the remaining net proceeds or Excess Cash Flow, as applicable, to prepay the outstanding principal amount of the Term Loan.

None of the payments received in 2013 from ODAC in connection with the "Net Libya Receivable" referred to above are payable under the Credit Agreement or the Term Loan because the amount was paid in Libyan dinars which is not a readily convertible currency. In addition, there were no sales of assets nor excess cash-flow (as defined in the "Third Amendment") generated in 2013.

In connection with the Term Loan Agreement, the Company incurred approximately $609,000 of costs which were charged to interest expense and related financing costs, net in 2012. In addition, the Company incurred costs of approximately $2,975,000 in connection with establishing the Term Loan. Such costs have been deferred and will be amortized to interest expense over the life of the Term Loan.

Other Debt Arrangements

The Company's subsidiary, Hill Spain, maintains a revolving credit facility with 12 banks (the "Financing Entities") in Spain providing for total borrowings, with interest at 6.50%, of up to €5,640,000 (approximately $7,788,000) at December 31, 2013. As of December 31, 2013 and 2012, total borrowings outstanding were €5,554,000 and €3,796,000 (approximately $7,670,000 and $5,021,000, respectively). The amount being financed ("Credit Contracts") by each Financing Entity is between €156,000 (approximately $215,000) and €689,000 (approximately $952,000). The facility expires on December 17, 2016. The maximum available amount will be reduced to 75.0% at December 31, 2014 and to 50.0% at December 31, 2015. To guarantee Hill Spain's obligations resulting from the Credit Contracts, Hill Spain provided a guarantee in favor of each one of the Financing Entities, which, additionally, and solely in the case of unremedied failure to make payment, and at the request of each of the Financing Entities, shall grant a first ranking pledge over a given percentage of corporate shares of Hill International Brasil Participacoes Ltda. for the principal, interest, fees, expenses or any other amount owed by virtue of the Credit Contracts, coinciding with the percentage of credit of each Financing Entity with respect to the total outstanding borrowings under this facility.

Hill Spain also maintains an unsecured credit facility with the Caja Badajoz bank in for €1,500,000 (approximately $2,071,000) as of December 31, 2013. The interest rate at December 31, 2013 is 5.75%. The rate at December 31, 2012 was the three-month EURIBOR rate of 0.54% plus 3.00% (or 3.54%) but no less than 5.00%. At December 31, 2013, €1,483,000 (approximately $2,047,000) was outstanding. At December 31, 2012 there were no borrowings outstanding. This facility was subsequently reduced to €1,000,000 on January 16, 2014 with an expiration date of December 23, 2014.

	2006 Employee Stock Option Plan

	The 2006 Employee Stock Option Plan, as amended, covers 8,000,000 shares of the Company's common stock. Under its terms, directors, officers and employees of the Company and its subsidiaries are eligible to receive non-qualified and incentive stock options. Options granted to non-employee directors vest immediately and have a five year contractual term. Options granted to officers and employees vest over five years and have a seven-year contractual term. Generally, each option has an exercise price equal to the closing quoted market price of a share of the Company's common stock on the date of grant. For grants of incentive stock options, if the grantee owns, or is deemed to own, 10% or more of the total voting power of the Company, then the exercise price shall be 110% of the closing quoted market price on the date of grant and the option will have a five-year contractual term. Options that are forfeited or expire are available for future grants. At December 31, 2013, a total of 1,366,844 shares of common stock were reserved for future issuance under the plan.

	The Black-Scholes option valuation model is used to estimate the fair value of the options. The following table summarizes the fair value of options granted during 2013, 2012 and 2011 and the assumptions used to estimate the fair value:


			December 31,
			2013		2012		2011
	Average expected life (years)		4.29		3.66		4.05
	Forfeiture range		0 - 5.0%		0%		0 - 10.5%
	Weighted average forfeiture rate		0.90%		0%		1.70%
	Dividends		0%		0%		0%
	Volatility range		67.8 - 73.5%		70.8 - 78.4%		44.6 - 67.5%
	Weighted average volatility		71.70%		77.50%		52.60%
	Range of risk-free interest rates		0.50 - 1.36%		0.36 - 0.86%		0.91 - 2.37%
	Weighted average risk-free interest rate		0.77%		0.80%		1.57%
	Weighted average fair value at grant date		$1.95		$2.52		$2.58

	The expected term of the options is estimated based on the "simplified method" as permitted by SAB No. 110. Expected volatility was calculated using the average historical volatility of similar public companies through June 30, 2011 and of the Company thereafter. The risk-free interest rate is based on U.S. Treasury yields for securities in effect at the time of grants with terms approximating the term of the grants. The assumptions used in the Black-Scholes option valuation model are highly subjective, particularly as to stock price volatility of the underlying stock, which can materially affect the resulting valuation.

	A summary of the Company's stock option activity and related information for the years ended December 31, 2013, 2012 and 2011 is as follows:

	The effective tax rates for the years ended December 31, 2013, 2012 and 2011 were 63.0%, (104.2%) and 55.6%, respectively. The difference in the Company's 2013 effective tax rate over 2012 was primarily the result of not recording an income tax benefit related to the 2013 U.S. net operating loss which management believes the Company will not be able to utilize. In addition, the Company recognized higher income tax expense related to withholding taxes on foreign operations. These items were partially offset by the $2,473,000 reversal for uncertain tax positions based on management's assessment that those items were effectively settled with a foreign jurisdiction.

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.

At December 31, 2012, due to recurring net operating losses in the United States, management determined that it was more likely than not that the Company would not be able to utilize its U.S.-related deferred tax assets. As a consequence, the Company recorded a valuation allowance of $17,707,000 at that time. In 2013, the Company recorded an additional U.S. deferred tax asset of $9,062,000 primarily related to a U.S.-based net operating loss of $24,902,000. Consequently, the Company recorded an additional valuation allowance at December 31, 2013 of $9,062,000. As a result, the U.S. deferred tax assets, net of U.S. based deferred tax liabilities, at December 31, 2013 are fully reserved. The total valuation allowance related to the U.S. deferred tax assets at December 31, 2013 is $26,769,000. Cumulative U.S. federal and state net operating losses at December 31, 2013 are $63,365,000 and $66,472,000, respectively.

At December 31, 2013 and 2012, there were approximately $24,013,000 and $20,337,000, respectively, of gross foreign net operating loss carry forwards. The majority of these net operating loss carry forwards have an unlimited carry forward period. A valuation allowance of $4,489,000 and $4,714,000 was recorded at December 31, 2013 and 2012, respectively, related to the foreign net operating losses in certain jurisdictions. It is anticipated that these losses will not be utilized due to continuing losses in these jurisdictions.

The Company has made no provision for U.S. taxes on $119,416,000 of cumulative earnings of foreign subsidiaries as those earnings are intended to be reinvested for an indefinite period of time. Upon distribution of these earnings in the form of dividends or otherwise, the Company may be subject to U.S. income taxes and foreign withholding taxes. It is not practical, however, to estimate the amount of taxes that may be payable on the eventual repatriation of these earnings.

In 2013, deferred tax assets and additional paid in capital were reduced by $583,000 and in 2012, deferred tax assets and additional paid in capital were increased by $161,000 to record the differential between book expense and tax expense related to the vesting of restricted stock.

The Company will recognize a tax benefit in the financial statements for an uncertain tax position only if management's assessment is that the position is "more likely than not" (i.e., a likelihood greater than 50 percent) to be allowed by the tax jurisdiction based solely on the technical merits of the position. The term "tax position" refers to a position in a previously filed tax return or a position expected to be taken in a future tax return that is reflected in measuring current or deferred income tax assets and liabilities for financial reporting purposes.

The following table indicates the changes to the Company's uncertain tax positions for the years ended December 31, 2013 and 2012 including interest and penalties:

The Company files income tax returns in the U.S. federal jurisdiction and in various state and foreign jurisdictions. The Company generally is no longer subject to U.S. federal, state or foreign examinations by tax authorities for tax years prior to 2010.

The Company's policy is to record income tax related interest and penalties in income tax expense. At December 31, 2013 and 2012, the Company has accrued $172,000 and $100,000, respectively, related to potential interest and penalties.

The Company's income tax returns are based on calculations and assumptions that are subject to examinations by the Internal Revenue Service and other tax authorities. While the Company believes it has appropriate support for the positions taken on its tax returns, the Company regularly assesses the potential outcomes of these examinations and any future examinations for the current or prior years in determining the adequacy of its provision for income taxes. As part of its assessment of potential adjustments to its tax returns, the Company increases its current tax liability to the extent an adjustment would result in a cash tax payment or decreases its deferred tax assets to the extent an adjustment would not result in a cash tax payment. The Company continually assesses the likelihood and amount of potential adjustments and adjusts the income tax provision, the current tax liability and deferred taxes in the period in which the facts that give rise to a revision become known.

	General Litigation

	M.A. Angeliades, Inc. ("Plaintiff") has filed a complaint with the Supreme Court of New York against the Company and the New York City Department of Design and Construction ("DDC") regarding payment of approximately $8,771,000 for work performed as a subcontractor to the Company plus interest and other costs. The Company has accrued approximately $2,340,000, including interest of $448,000, based on invoices received from Plaintiff who has refused to provide invoices for the additional work that Plaintiff claims to have performed. Until such time as the Company obtains invoices for the additional work and is able to provide those invoices to DDC for reimbursement or there is a full resolution of the litigation, it has no intention of paying Plaintiff. The Company believes that its position is defensible, however, there can be no assurance that it will receive a favorable verdict should this case proceed to trial.

	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.

	Off-Balance Sheet Arrangements

	The Company enters into agreements with banks for the banks to issue bonds to clients or potential clients for three separate purposes as follows:



	-1
	Certain of the Company's subsidiaries (Hill International S.A., Hill International (UK) Ltd. and Hill International (Middle East) Ltd.) have entered into contracts for the performance of construction management services which provide that the Company receive advance payment of some of the management fee from the client prior to commencement of the construction project. However, the clients require a guarantee of service performance in the form of an advance payment bond. These bonds are evidenced by Letters of Guarantee issued by the subsidiaries' banks in favor of the clients. In some cases these clients also require a parent company guarantee.

	-2
	The Company may also enter into certain contracts which require a performance bond to be issued by a bank in favor of the client for a portion of the value of the contract. These bonds may be exercised by the client in instances where the Company fails to provide the contracted services.

	-3
	Certain clients may require bonds as part of the bidding process for new work. The bid bonds are provided to demonstrate the financial strength of the companies seeking the work and are usually outstanding for short periods. If the bid is rejected the bond is cancelled and if the bid is accepted the Company may be required to provide a performance bond.

	The maximum potential future payment under these arrangements at December 31, 2013 was $71,433,000.

	Cash held in restricted accounts as collateral for the issuance of performance and advance payment bonds and letters of credit at December 31, 2013 and 2012 were $18,506,000 and $21,226,000, respectively.

	Acquisition-related

	On February 28, 2011, the Company's wholly-owned subsidiary Hill Spain acquired an indirect 60% interest in Engineering S.A. ("ESA"), a firm located in Brazil, for cash amounting to 22,200,000 Brazilian Reais ("BR") (approximately $11,757,000). Minimum additional payments were made on April 30, 2012 in the amount of BR 6,624,000 (approximately $3,508,000 on that date) and on July 23, 2013 in the amount of BR 11,372,000 (approximately $5,095,000). Under certain circumstances, the Company may be required to pay BR 5,000,000 (approximately $2,468,000 at December 31, 2012) in addition to the minimum payments. Also, 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.

	The Company is committed to issue shares of its common stock to the former shareholders of BCA in satisfaction of the Third Tranche Payment, the amount of which will be determined in mid-2014. See Note 3.

	The Company is committed to issue shares of its common stock to the former shareholders of CPI for certain contingent consideration. The number of shares will be determined at various times during 2014. See Note 3.

	Other

	On December 31, 2012, the Company identified a potential employment tax liability related to certain foreign subsidiaries' treatment of certain individuals as independent contractors rather than as employees. On June 24, 2013, the Company received an indemnification from the selling shareholders for periods prior to 2013. Accordingly, the Company has reversed the accrual established in 2012 and has reflected approximately $3,600,000 as a credit to selling, general and administrative expenses in the consolidated statement of operations for the year ended December 31, 2013. In consideration for the indemnification, the Company reversed the 2013 first quarter write-down of the liabilities for the second installment obligation of approximately 1,950,000 BRL (approximately $873,000). In addition, the Company believes, based upon certain professional advice that it is remote that a future liability will be established for the potential employment taxes relating to certain foreign independent contractors and, therefore, has made no accrual for such potential liability.
