Notes to Unaudited Consolidated Financial Statements

Six Months Ended June 30, 2018 and 2017

1. Summary of Significant Accounting Policies

Basis of Presentation

The consolidated financial statements include the accounts of Echo Global Logistics, Inc. and its subsidiaries (the "Company" or "Echo"). All significant intercompany accounts and transactions have been eliminated in the consolidation. The consolidated statements of operations include the results of entities or assets acquired from the effective date of the acquisition for accounting purposes.

The preparation of the consolidated financial statements is in conformity with the rules and regulations of the Securities and Exchange Commission ("SEC") and accounting principles generally accepted in the United States ("U.S. GAAP") for interim financial information. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules or regulations. In the opinion of management, the accompanying unaudited financial statements reflect all adjustments considered necessary for a fair presentation of the results for the period and those adjustments are of a normal recurring nature. The operating results for the six months ended June 30, 2018 are not necessarily indicative of the results expected for the full year 2018. These interim consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's audited financial statements for the year ended December 31, 2017.

Preparation of Financial Statements and Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results can differ from those estimates.

Fair Value of Financial Instruments

The carrying values of the Company's financial instruments, which consist of cash and cash equivalents, accounts receivable and accounts payable, approximate their fair values due to their short-term nature. The fair value of the due to seller liabilities are determined based on the likelihood of the Company making contingent earn-out payments (see Note 4). The fair value of the liability component of the Notes (as defined in Note 11) was determined using the discounted cash flow analysis discussed in Note 11.

2. Recent Accounting Pronouncements

Recently adopted accounting pronouncements

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers, to clarify the principles used to recognize revenue for all entities. This new standard requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled for those goods or services. In addition, the new standard requires enhanced qualitative and quantitative disclosures related to the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers.

The Company adopted this standard on January 1, 2018 using the modified retrospective approach. As a result of using this approach, the Company recognized the cumulative effect adjustment to the opening balance of retained earnings. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods.

The adoption of this new standard adjusted the revenue recognition timing of the Company's brokerage and transportation management services performance obligation from point in time to over time on a relative transit time basis, which resulted in a cumulative transition adjustment to the opening balance of retained earnings, on January 1, 2018, of $1.1 million, net of tax, and an increase of $3.3 million to revenue for the six months ended June 30, 2018. While adoption of this standard also effects the corresponding direct costs of revenue, including commission, this change did not have a material

Notes to Unaudited Consolidated Financial Statements

impact on the Company's consolidated financial statements due to the short term nature of its performance obligations. The Company fully describes the adoption and impact of this standard in Note 3 to the consolidated financial statements. As part of the adoption of this standard, the Company implemented changes to its accounting policies, practices and internal controls over financial reporting.

In March 2018, the FASB issued ASU 2018-05, Income Taxes, to clarify the accounting implications of Staff Accounting Bulletin No. 118 ("SAB 118"). SAB 118 provides a measurement period that should not extend beyond one year from December 22, 2017, the date of the enactment of the Tax Cuts and Jobs Act (the "Act"), to complete the accounting under Accounting Standards Codification ("ASC") 740, Income Taxes. As of June 30, 2018, the Company has not adjusted the provisional estimate of $8.9 million recorded as a decrease to the net deferred tax liability at December 31, 2017. The Company expects to complete its analysis within the measurement period in accordance with SAB 118.

In May 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation, to provide guidance regarding which changes to a share-based payment award require modification accounting in Topic 718. The Company adopted this standard prospectively on January 1, 2018. The impact of this new standard is dependent on future modifications, if any, to the Company's share-based payment awards. For the six months ended June 30, 2018, the adoption of this standard had no impact on the consolidated financial statements.

In January 2017, the FASB issued ASU 2017-01, Business Combinations: Clarifying the Definition of a Business, to clarify the definition of a business to assist entities when evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The Company adopted this standard prospectively on January 1, 2018. The impact of this new standard is dependent on future acquisitions. For the six months ended June 30, 2018, the adoption of this standard did not have an impact on the consolidated financial statements as no acquisitions took place during the quarter.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows,to clarify the classification of certain cash receipts and cash payments in the statement of cash flows, including debt prepayment or extinguishment costs and settlement of contingent consideration arising from an acquisition. The Company adopted this standard on January 1, 2018, using the full retrospective method (prior periods have been restated). For the six months ended June 30, 2018 and 2017, cash payments in excess of the contingent consideration liability recognized at the acquisition date were recorded as an operating activity in the consolidated statements of cash flows.

Recently issued accounting pronouncements not yet adopted

In June 2018, the FASB issued ASU 2018-07, Compensation - Stock Compensation, which expands the scope of Topic 718 to include all share-based payment transactions for acquiring goods and services from nonemployees. The amendments in this update will be effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. The Company is evaluating the effects that the adoption of this guidance will have on its consolidated financial statements.

In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other: Simplifying the Test for Goodwill Impairment, to simplify the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. This new accounting standard will be effective for annual periods beginning after December 15, 2019. Early adoption is permitted. The Company is evaluating the effects that the adoption of this guidance will have on its consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases, requiring a lessee to record, on the balance sheet, the assets and liabilities for the right-of-use assets and lease obligations created by leases with lease terms of more than 12 months. This new accounting standard will be effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. The original guidance required application on a modified retrospective basis with respect to the earliest period presented. During March 2018, the FASB approved amendments to create an optional transition method that will provide an option to use the effective date of ASC 842, Leases, as of the date of initial application of the transition. The Company plans to adopt this optional transition standard on January 1, 2019. Upon adoption, the Company plans to use the package of practical expedients that allows it to (i) not reassess whether an arrangement contains a lease, (ii) carry forward its lease classification as operating or capital leases and (iii) not reassess its previously recorded initial direct costs. Adoption will also require enhanced qualitative and quantitative disclosures. The Company anticipates that the adoption of this standard will materially affect its consolidated balance sheets.

3. Revenue

Adoption of ASC Topic 606, "Revenue from Contracts with Customers"

On January 1, 2018, the Company adopted ASU 2014-09, Revenue from Contracts with Customers ("ASC Topic 606"), using the modified retrospective method. Results for reporting periods beginning on or after January 1, 2018 are presented under ASC Topic 606; however, prior period amounts are not adjusted and continue to be reported in accordance with the accounting standards in effect for those periods.

The Company recorded an increase to the opening balance of retained earnings of $1.1 million, net of tax, as of January 1, 2018 due to the cumulative impact of adoption of ASC Topic 606. The impact to revenue for the six months ended June 30, 2018 was an increase of $3.3 million, as a result of applying ASC Topic 606.

Revenue Recognition

Revenue is recognized when control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration the Company expects to receive in exchange for its services. The Company generates revenue from two different client types: Transactional and Managed Transportation. Most clients are categorized as Transactional clients. For the Transactional business, the Company provides brokerage and transportation management services on a shipment-by-shipment basis. Carrier selection, dispatch, load management and tracking are integrated services that occur within the brokerage and transportation management performance obligation. For the brokerage and transportation management performance obligation, revenue is recognized as the client's shipment travels from origin to destination by a third-party carrier. The Company is the principal in these transactions and recognizes revenue on a gross basis on a relative transit time basis. The Company categorizes a client as a Managed Transportation client if there is an agreement with the client for the provision of services, typically for a multi-year term. Brokerage and transportation management services can also be performance obligations for the Company's Managed Transportation clients. Other performance obligations for Managed Transportation clients may include transportation management services, which includes the integrated services of dispatch, tracking and carrier payment. For these types of transactions, revenue is recorded on a net basis as we do not have latitude in carrier selection or establish rates with the carrier. The Company also performs project-based services, such as compliance management, customized re-billing services and freight studies for certain Managed Transportation clients.

The following table presents the Company's revenue disaggregated by client type (in thousands, unaudited):

	Three months ended June 30,				Six months ended June 30,
Client Type	2018		2017(1)		2018		2017(1)

Revenue	$	634,811	$	470,086	$	1,211,902	$	885,838

⁽¹⁾ Prior period amounts have not been adjusted under the modified retrospective method.

Revenue recognized per shipment varies depending on the transportation mode. The primary modes of shipment in which the Company transacts are truckload and less than truckload. Other transportation modes include intermodal, small parcel, domestic air, expedited and international.

Variable Consideration

Certain customers may receive rebates based on the terms of their agreement with the Company, which are accounted for as variable consideration. Rebates are estimated based on the expected amount to be provided to customers and reduce revenue recognized. The Company also estimates for possible additional fees based on a portfolio approach.

Practical Expedients

The Company adopted the practical expedient to recognize commission expense when incurred because the amortization period is less than one year. Commission expense recognition aligns with the Company's revenue recognition policy under ASC Topic 606, as commission expense is recognized on a relative transit time basis.

The Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed.

4. Fair Value Measurement

The Company applies ASC Topic 820, Fair Value Measurements and Disclosures ("ASC Topic 820"), for its financial assets and financial liabilities. The guidance requires disclosures about assets and liabilities measured at fair value. The Company's financial liabilities primarily relate to contingent earn-out payments due to sellers in connection with various acquisitions. The fair value of the due to seller liabilities at June 30, 2018 was $1.3 million. The potential earn-out payments and performance periods are defined in the individual purchase agreements for each acquisition. Earnings before interest, taxes, depreciation and amortization ("EBITDA") is the performance target defined and measured to determine the earn-out payment due, if any, after each defined measurement period.

The Company's financial assets related to contingent payments that were due from the seller of Command Transportation, LLC ("Command") based upon certain employee retention criteria. As of June 30, 2018, there was no remaining balance of the due from seller asset as the criteria were met.

ASC Topic 820 includes a fair value hierarchy that is intended to increase consistency and comparability in fair value measurements and related disclosures. The fair value hierarchy is based on observable or unobservable inputs to valuation techniques that are used to measure fair value. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources while unobservable inputs reflect a reporting entity's pricing based upon its own market assumptions. The fair value hierarchy consists of the following three levels:

• Level 1: Inputs are quoted prices in active markets for identical assets or liabilities.

• Level 2: Inputs are quoted prices for similar assets or liabilities in an active market, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs other than quoted prices that are observable and market-corroborated inputs, which are derived principally from or corroborated by observable market data.

• Level 3: Inputs that are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable.

The significant inputs used to derive the fair value of the amounts due to seller include financial forecasts of future operating results, the probability of reaching the forecast and an appropriate discount rate for each contingent liability. Probabilities are estimated by reviewing financial forecasts and assessing the likelihood of reaching the required performance measures based on factors specific to each acquisition as well as the Company’s historical experience with similar arrangements. If an acquisition reaches the required performance measure, the estimated probability would be increased to 100% and would still be classified as a contingent liability on the balance sheet. If the measure is not reached, the probability would be reduced to reflect the amount earned, if any, depending on the terms of the agreement. Discount rates used in determining the fair value of the contingent consideration due to seller ranged from 5% to 6%. Historical results of the respective acquisitions serve as the basis for the financial forecasts used in the valuation.

Quantitative factors are also considered in these forecasts, including acquisition synergies, growth and sales potential and potential operational efficiencies gained. Changes to the significant inputs used in determining the fair value of the contingent

consideration due to seller could result in a change in the fair value of the contingent consideration. However, the correlation and inverse relationship between higher projected financial results to the discount rate applied and probability of meeting the financial targets mitigates the effect of any changes to the unobservable inputs.

The following tables set forth the Company's financial liabilities measured at fair value on a recurring basis and the basis of measurement at June 30, 2018 and December 31, 2017 (in thousands):

	Fair Value Measurements as of June 30, 2018
	Total			Level 1	Level 2	Level 3
Liabilities:
Contingent consideration due to seller	$	(1,250	)	—	—	$	(1,250	)

	Fair Value Measurements as of December 31, 2017
	Total			Level 1	Level 2	Level 3
Liabilities:
Contingent consideration due to seller	$	(2,075	)	—	—	$	(2,075	)

The following table provides a reconciliation of the beginning and ending balances for the liabilities measured at fair value using significant unobservable inputs (Level 3) (in thousands):

	Due to Seller Liability
Balance at December 31, 2017	$	(2,075	)
Change in fair value of contingent consideration due to seller	(100		)
Payment of contingent consideration due to seller	925
Balance at June 30, 2018	$	(1,250	)

For the three months ended June 30, 2018 and 2017, the Company recognized net expense of $50 thousand and $194 thousand, respectively, in selling, general and administrative expenses due to the change in fair value determined by a Level 3 valuation technique. For the six months ended June 30, 2018 and 2017, the Company recognized net expense of $100 thousand and $286 thousand, respectively. These changes in fair value resulted from using revised forecasts that took into account the most recent performance at each acquired business, the effect of the time value of money and the satisfaction of the employee retention criteria.

During the six months ended June 30, 2018 and 2017, the Company made contingent earn-out payments of $925 thousand and $695 thousand, respectively, to the sellers of businesses acquired by the Company. The Company did not receive any contingent payments from the seller of Command during the six months ended June 30, 2018. The Company received $500 thousand of contingent payments from the seller of Command during the six months ended June 30, 2017.

5. Intangibles and Goodwill

The balance of goodwill was $307.3 million as of June 30, 2018 and December 31, 2017, as no changes occurred during the period.

The following is a summary of amortizable intangible assets as of June 30, 2018 and December 31, 2017 (in thousands):

	June 30, 2018							December 31, 2017
	Cost		Accumulated Amortization			Net		Cost		Accumulated Amortization			Net
Customer relationships	$	145,139	$	(52,931	)	$	92,208	$	145,139	$	(48,058	)	$	97,081
Carrier relationships	18,300		(3,319		)	14,981		18,300		(2,781		)	15,519

Note: Amounts may not foot due to rounding.

The customer relationships are being amortized using an accelerated method over their estimated weighted-average useful life of 14.8 years, as an accelerated method best approximates the distribution of cash flows generated by the acquired customer relationships. The carrier relationships, non-compete agreements and trade names are being amortized using the straight-line method over their estimated weighted-average useful lives of 17.0 years, 6.7 years and 4.0 years, respectively. Amortization expense related to intangible assets was $3.2 million and $3.6 million for the three months ended June 30, 2018 and 2017, respectively, and $6.5 million and $7.1 million for the six months ended June 30, 2018 and 2017, respectively.

The estimated amortization expense for the next five years and thereafter is as follows (in thousands):

Remainder of 2018	$	6,386
2019	11,471
2020	10,639

7. Income Taxes     

On December 22, 2017, the Act was signed into legislation. The Act became effective January 1, 2018 and reduced the federal corporate tax rate from 35% to 21%.

In March 2018, the FASB issued ASU 2018-05, Income Taxes, which provides guidance on accounting for the tax effects of SAB 118, as discussed in Note 2. SAB 118 provides a measurement period that should not extend beyond one year from December 22, 2017 to complete the accounting under the Act. As of June 30, 2018, the Company has not adjusted the provisional estimate of $8.9 million recorded as a decrease to the net deferred tax liability at December 31, 2017. The Company considers the deferred tax re-measurements, and other items to be reasonable estimates, but provisional, due to the forthcoming guidance and its ongoing analysis of final year-end data and tax provisions. The Company expects to complete its analysis within the measurement period in accordance with SAB 118.

The following table shows the Company's effective income tax rate for the three and six months ended June 30, 2018 and 2017 (in thousands):

	Three Months Ended June 30,						Six Months Ended June 30,
	2018			2017			2018			2017
Income (Loss) before provision for income taxes	$	9,358		$	(239	)	$	16,107		$	(4,640	)
Income tax (expense) benefit	$	(1,680	)	$	(6	)	$	(3,702	)	$	1,523
Effective tax rate	17.9		%	2.7		%	23.0		%	(32.8		)%

The difference in the Company's effective tax rate for the three months ended June 30, 2018 from the Company's statutory federal tax rate of 21% was primarily due to tax benefits associated with stock-based compensation exercises, while the difference in the Company's effective tax rate for the six months ended June 30, 2018 from the Company's statutory federal tax rate was primarily due to state taxes; an increase in non-deductible expenses, primarily executive stock-based compensation; offset in part by the impact of certain tax credits.

The difference in the Company's effective tax rate for the three months ended June 30, 2017 from the company's federal tax rate of 35% was primarily due to net tax deficiencies related to share-based payment awards recognized as income tax expense in accordance with ASU 2016-09, Compensation - Stock Compensation: Improvements to Employee Share-Based Payment Accounting and lower income before taxes during the quarter, while the difference in the Company's effective tax rate for the six months ended June 30, 2017 was primarily due to the net tax deficiencies related to share-based payment awards, completion of a state tax audit and the effect of the 2017 year to date pre-tax loss.

8. Earnings (Loss) Per Share

Basic earnings (loss) per common share is calculated by dividing net income (loss) by the weighted average number of common shares outstanding. Diluted earnings (loss) per common share is calculated by dividing net income (loss) by the weighted average shares outstanding plus share equivalents that would arise from the exercise of share options and the vesting of restricted stock and performance shares. The computation of basic and diluted earnings (loss) per common share for the three and six months ended June 30, 2018 and 2017 is as follows (in thousands, except share and per share data):

	Three Months Ended June 30,					Six Months Ended June 30,
	2018		2017			2018		2017
Numerator:
Net income (loss)	$	7,678	$	(245	)	$	12,405	$	(3,117	)
Denominator:
Denominator for basic earnings (loss) per common share - weighted-average shares	27,603,096		28,016,122			27,466,689		28,085,710
Effect of dilutive securities:
Employee stock awards	268,850		—			332,249		—
Denominator for dilutive earnings (loss) per common share	27,871,946		28,016,122			27,798,938		28,085,710
Basic earnings (loss) per common share	$	0.28	$	(0.01	)	$	0.45	$	(0.11	)
Diluted earnings (loss) per common share	$	0.28	$	(0.01	)	$	0.45	$	(0.11	)

For the three and six months ended June 30, 2018, the Company excluded 2,538 unvested performance and market-based shares from the calculation of diluted earnings per common share because the effect was anti-dilutive. There were no employee stock options and no unvested restricted stock excluded from the calculation of diluted earnings per common share. For the three and six months ended June 30, 2017, 239,440 and 331,618 incremental shares related to stock-based awards were not included in the computation of diluted loss per common share because of the net loss during the respective periods.

As of June 30, 2018, none of the conditions allowing holders of the Notes to convert have been met and no conversion spread exists. As such, the Notes did not have a dilutive impact on diluted earnings (loss) per common share for the three and six months ended June 30, 2018 and 2017, respectively.

9. Stock-Based Compensation Plans

The Company recorded $2.2 million and $4.7 million in total stock-based compensation expense with corresponding income tax benefits of $0.5 million and $1.2 million for the three and six months ended June 30, 2018, respectively. For the three and six months ended June 30, 2017, the Company recorded $2.4 million and $5.1 million in total stock-based compensation expense with corresponding income tax benefits of $0.9 million and $1.9 million, respectively.

During each of the six months ended June 30, 2018 and 2017, the Company did not grant any stock options.

The Company granted 244,448 and 280,853 shares of restricted stock to various employees during the six months ended June 30, 2018 and 2017, respectively.

In 2014, the Company initiated a performance and market-based stock incentive plan for certain executives that provides vesting based on specific financial and market-based performance measurements. The Company granted 97,966 and 99,933 shares of performance and market-based stock during the six months ended June 30, 2018 and 2017, respectively.

10. Contingencies

In the normal course of business, the Company is subject to potential claims and disputes related to its business, including claims for freight lost or damaged in transit. Some of these matters may be covered by the Company's insurance and risk management programs or may result in claims or adjustments with the Company's carriers. No such matters are currently expected to have a material adverse effect on the Company's financial position, results of operations or cash flows.

In July 2016, the Company received an unfavorable appeals assessment regarding a state activity-based tax matter of $1.3 million, including penalties and interest, for the state tax audit period from January 1, 2010 to June 30, 2014. The Company believes the assessment is without merit and is currently defending the Company's position through a formal appeals process. The Company has not recorded any potential loss related to this matter as of June 30, 2018.

11. Long-Term Debt

ABL Facility

On June 1, 2015, the Company and Command, as co-borrowers, entered into a Revolving Credit and Security Agreement (the “Credit Agreement”) with PNC Bank. The Credit Agreement provides for a senior secured revolving credit facility in an initial aggregate principal amount of up to $200 million (the “ABL Facility”). The Company's obligations under the ABL facility are secured, on a first lien priority basis, by certain working capital assets. The initial aggregate principal amount under the ABL Facility may be increased from time to time by an additional $100 million to a maximum aggregate principal amount of $300 million.

Interest is payable at a rate per annum equal to, at the option of the Company, any of the following, plus, in each case, an applicable margin: (a) a base rate determined by reference to the highest of (1) the federal funds effective rate, plus 0.50%, (2) the base commercial lending rate of PNC Bank, National Association and (3) a daily LIBOR rate, plus 1.00%; or (b) a LIBOR rate determined by reference to the costs of funds for deposits in the relevant currency for the interest period relevant to such borrowing adjusted for certain additional costs. The applicable margin is 0.25% to 0.75% for borrowings at the base rate and 1.25% to 1.75% for borrowings at the LIBOR rate, in each case, based on the excess availability under the ABL Facility.

The Company is required to pay a commitment fee in respect to the unutilized commitments under the revolving credit facility. At June 30, 2018, the Company's commitment fee was calculated at a rate of 0.375%. The Company recognized interest expense related to the commitment fee and borrowings on the ABL Facility of $0.2 million for each of the three months ended June 30, 2018 and 2017, and $0.4 million and $0.5 million for each of the six months ended June 30, 2018 and 2017, respectively.

The Company drew $12.0 million and $32.0 million on the ABL Facility during the six months ended June 30, 2018 and 2017, respectively, all of which was repaid as of June 30, 2018 and 2017. No amounts were outstanding on the ABL Facility as of June 30, 2018. The Company is in compliance with all covenants related to the ABL Facility.

The issuance of letters of credit under the ABL Facility reduces available borrowings. At June 30, 2018, there were $0.7 million of letters of credit outstanding. The total draw allowed on the ABL Facility at June 30, 2018, as determined by the working capital assets pledged as collateral, was $200.0 million. After adjusting for the letters of credit, the Company's remaining availability under the ABL Facility at June 30, 2018 was $199.3 million.

The Company incurred issuance costs of $3.1 million in 2015 related to the ABL Facility. These issuance costs are being amortized to interest expense using straight-line amortization over the 5 year life of the ABL Facility. For each of the three and six months ended June 30, 2018 and 2017, the Company recorded $0.2 million and $0.4 million of interest expense related to ABL Facility issuance costs, respectively. As there is no outstanding draw on the ABL Facility at June 30, 2018, the unamortized issuance costs are presented as a deferred asset on the consolidated balance sheets.

Convertible Senior Notes

On May 5, 2015, the Company issued $230 million aggregate principal amount of 2.50% convertible senior notes due 2020 (the “Notes”). The Company used all of the net proceeds from the note offering (together with the proceeds from the sale of common stock and borrowings under the ABL Facility) to finance the acquisition of Command in June 2015.

The Notes bear interest at a rate of 2.50% per year payable semiannually in arrears in cash on May 1 and November 1 of each year, beginning on November 1, 2015. The Notes will mature on May 1, 2020, unless earlier converted or repurchased in accordance with the terms discussed below. The Notes are the Company's senior unsecured obligations and rank senior in right of payment to any of the Company's indebtedness that is expressly subordinated in right of payment to the Notes; equal in right of payment to any of the Company's unsecured indebtedness that is not so subordinated; effectively junior in right of payment

to any of the Company's secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities (including trade payables) of the Company's subsidiaries.

The Notes will be convertible, under certain circumstances and during certain periods, into cash, shares of the Company's common stock, or a combination of cash and shares of common stock at the Company's election, at an initial conversion rate of 25.5428 shares of common stock per $1,000 principal amount of Notes, which is equivalent to an initial conversion price of approximately $39.15 per share of common stock.

The Company's intent and policy will be to settle the $230 million principal amount of Notes in cash, and any excess conversion premium in shares of common stock. As such, the principal amount of the Notes will not be included in the calculation of diluted earnings (loss) per common share, but any conversion premium that exists will be included in the calculation of diluted earnings (loss) per common share using the treasury stock method. As of June 30, 2018, none of the conditions allowing holders of the Notes to convert have been met and no conversion spread exists. As such, the Notes did not have a dilutive impact on diluted earnings (loss) per common share for each of the six months ended June 30, 2018 and 2017.

At issuance, the Company estimated the straight debt borrowing rates at issuance to be 5.75% for similar debt to the Notes without the conversion feature, which resulted in a fair value of the liability component of $198.5 million and a fair value of the equity component of $31.5 million. The fair value of the equity component was recorded as a debt discount, with the offset recorded as a credit to additional paid-in capital within stockholders' equity. The $31.5 million debt discount and Note issuance costs discussed below are being amortized to interest expense under the effective interest method over the 5 year life of the Notes, using an effective interest rate of 6.33%.

The Company allocated the total issuance costs related to the Notes to the liability and equity components based on their relative fair values. Issuance costs attributable to the liability component were recorded on the consolidated balance sheets as a contra-liability that reduces the carrying amount of the convertible note liability. This amount is being amortized to interest expense over the term of the Notes using the effective interest method and an effective interest rate of 6.33%. Issuance costs attributable to the equity component were recorded as a charge to additional paid-in capital within stockholders' equity.

As of June 30, 2018 and December 31, 2017, the carrying amounts of the Notes on the consolidated balance sheets were calculated as follows (in thousands):

	June 30, 2018			December 31, 2017
Convertible senior notes, principal amount	$	230,000		$	230,000
Unamortized debt discount	(12,712		)	(15,930		)
Unamortized debt issuance costs	(2,514		)	(3,151		)
Convertible senior notes, net	$	214,774		$	210,919

The Notes are carried on the consolidated balance sheets at their principal amount, net of the unamortized debt discount and unamortized debt issuance costs, and are not marked to market each period. The approximate fair value of the Notes as of June 30, 2018 was $238.1 million. The fair value of the Notes was estimated based on the trading price of the Notes at June 30, 2018. As trading volume is low, these are quoted prices for identical instruments in markets that are not active, and thus are Level 2 in the fair value hierarchy.

For the three and six months ended June 30, 2018 and 2017, interest expense related to the Notes consisted of the following (in thousands):

	Three months ended June 30,				Six months ended June 30,
	2018		2017		2018		2017
Contractual coupon interest	$	1,438	$	1,438	$	2,875	$	2,875
Debt discount amortization	1,622		1,523		3,219		3,022
Debt issuance cost amortization	321		301		637		598
Interest expense, Notes	$	3,380	$	3,261	$	6,730	$	6,494

We generate revenue through the sale of brokerage and transportation management services to our clients. For our brokerage and transportation management services, revenue is recognized as the client's shipment travels from origin to destination by a third-party carrier. Our revenue was $1.2 billion and $0.9 billion for the six months ended June 30, 2018 and 2017, respectively, representing a period-over-period increase of 36.8%.

Our revenue is generated from two different types of clients: Transactional and Managed Transportation. Most of our clients are categorized as Transactional clients. We provide services to our Transactional clients on a shipment-by-shipment basis. We categorize a client as a Managed Transportation client if we have a contract with the client for the provision of services on a recurring basis. Our contracts with Managed Transportation clients typically have a multi-year term and are often on an exclusive basis for a specific transportation mode or point of origin. In several cases, we provide substantially all of a client's transportation and logistics requirements. Our Managed Transportation accounts typically generate higher dollar amounts and volume than our Transactional relationships. For the six months ended June 30, 2018 and 2017, Transactional clients accounted for 78.9% and 79.5% of our revenue, respectively, and Managed Transportation clients accounted for 21.1% and 20.5% of our revenue, respectively. We expect to continue to grow both our Transactional and Managed Transportation client base in the future, although the rate of growth for each type of client will vary depending on opportunities in the marketplace.

Revenue recognized per shipment will vary depending on the transportation mode, fuel prices, shipment weight, density and mileage of the product shipped. The primary modes of shipment that we transact in are TL and LTL. Other transportation modes include intermodal, small parcel, domestic air, expedited and international. Material shifts in the percentage of our revenue by transportation mode could have a significant impact on our revenue growth. For the six months ended June 30, 2018, TL accounted for 69.7% of our revenue, LTL accounted for 25.4% of our revenue and other transportation modes accounted for 4.9% of our revenue. For the six months ended June 30, 2017, TL accounted for 67.2% of our revenue, LTL accounted for 27.5% of our revenue and other transportation modes accounted for 5.3% of our revenue.

The transportation industry has historically been subject to seasonal sales fluctuations as shipments generally are lower during and after the winter holiday season because many companies ship goods and stock inventories prior to the winter holiday season. While we experience some seasonality, differences in our revenue between periods have been driven primarily by growth in our client base and changes in the market environment.

Transportation costs and net revenue

We act primarily as a service provider to add value and expertise in the procurement and execution of transportation and logistics services for our clients. Our pricing structure is primarily variable, although we have entered into a limited number of fixed-fee arrangements that represent an insignificant portion of our revenue. Net revenue equals revenue minus transportation costs. Our transportation costs consist primarily of the direct cost of transportation paid to the carrier.

Net revenue is considered by management to be an important measurement of our success in the marketplace. Our transportation costs are typically lower for an LTL shipment than for a TL shipment, while our net revenue margin is typically higher for an LTL shipment than for a TL shipment. Material shifts in the percentage of our revenue by transportation mode could have a significant impact on our net revenue. The discussion of our results of operations below focuses on changes in our net revenue and expenses as a percentage of net revenue. Net revenue for the six months ended June 30, 2018 was $206.7 million, an increase of 32.4% from $156.1 million in the comparable period of 2017.

Operating expenses

Our costs and expenses, excluding transportation costs, consist of commissions paid to our sales personnel; selling, general and administrative expenses to run our business; changes in our contingent consideration; and depreciation and amortization.

Commissions paid to our sales personnel, including employees and agents, are a significant component of our operating expenses. These commissions are based on the net revenue we collect from the clients for which such sales personnel have primary responsibility. For the six months ended June 30, 2018 and 2017, our commission expense was $62.6 million and $47.1 million, respectively. Commission expense increased to 30.3% of our net revenue as of June 30, 2018, as compared to 30.2% in the prior year. The percentage of net revenue paid as commissions will vary depending on the type of client, composition of the sales team and mode of transportation. Commission expense, stated as a percentage of net revenue, could increase or decrease in the future depending on the composition and sources of our revenue growth.

20

We accrue for commission expense when we recognize the related revenue on a relative transit time basis. Some of our sales personnel receive a monthly advance to provide them with a more consistent income stream. Cash paid to our sales personnel in advance of commissions earned is recorded as a prepaid expense. As our sales personnel earn commissions, a portion of their commission payment is withheld and offset against their prepaid commission balance, if any.

Selling, general and administrative expenses, excluding commission expense and changes to contingent consideration, consist of compensation costs for our sales, operations, information systems, finance and administrative support employees as well as occupancy costs, professional fees, stock compensation and other general and administrative expenses. For the six months ended June 30, 2018 and 2017, our selling, general and administrative expenses were $102.5 million and $90.0 million, respectively. For the six months ended June 30, 2018 and 2017, selling, general and administrative expenses as a percentage of net revenue were 49.6% and 57.7%, respectively.

Our contingent consideration expense is the change in the fair value of our contingent consideration assets and liabilities. The contingent consideration assets and liabilities presented on our consolidated balance sheets reflect the fair value of expected earn-out payments that may be paid or received from the sellers of certain acquired businesses upon the achievement of certain performance measures. The fair values of the contingent consideration assets and liabilities are evaluated on a quarterly basis, and the change in fair value is included in selling, general and administrative expenses in our consolidated statements of operations. For the six months ended June 30, 2018 and 2017, we recorded a net expense of $0.1 million and $0.3 million, respectively.

Our depreciation expense is primarily attributable to depreciation of computer hardware and software, equipment, leasehold improvements, furniture and fixtures and internally developed software. For the six months ended June 30, 2018 and 2017, depreciation expense was $11.5 million and $8.9 million, respectively.

Our amortization expense is attributable to amortization of intangible assets acquired from business combinations, including customer and carrier relationships, trade names and non-compete agreements. For the six months ended June 30, 2018 and 2017, amortization expense was $6.5 million and $7.1 million, respectively.

Interest expense

The interest expense included in our consolidated statements of operations consists of interest expense related to our $230 million aggregate principal amount of 2.50% convertible senior notes due 2020 issued in May 2015 (the "Notes") and our senior secured revolving credit facility in an initial aggregate principal amount of up to $200 million entered into in June 2015 (the "ABL Facility"). We amortize the debt discount and issuance costs related to the Notes over the 5 year life of the Notes using the effective interest method. We amortize the issuance costs related to our ABL Facility over the 5 year life of the facility using straight-line amortization, as the amount drawn on the line (and thus the interest rate and commitment fee paid by Echo) will fluctuate from period to period. Interest expense was $7.5 million and $7.3 million for the six months ended June 30, 2018 and 2017, respectively.

Comparison of the three months ended June 30, 2018 and 2017

Revenue

Revenue for the three months ended June 30, 2018 was $634.8 million, an increase of 35.0% from $470.1 million in the comparable period of 2017. The increase in revenue was primarily attributable to an increase of 24.5% in revenue per shipment, along with an increase of 8.4% in volume.

Revenue from Transactional clients for the three months ended June 30, 2018 was $502.8 million, an increase of 35.4% from $371.4 million in the comparable period of 2017. The increase in Transactional revenue was driven by an increase in both TL and LTL volume and revenue per shipment. Revenue from Transactional clients was 79.2% of our revenue for the three months ended June 30, 2018, an increase from 79.0% of our revenue in the comparable period of 2017.

Revenue from Managed Transportation clients for the three months ended June 30, 2018 was $132.0 million, an increase of 33.8% from $98.7 million in the comparable period of 2017. Revenue from Managed Transportation clients was 20.8% of our revenue for the three months ended June 30, 2018, a decrease from 21.0% of revenue in the comparable period of 2017. This decrease in Managed Transportation revenue as a percent of total revenue was driven by the increases in Transactional revenue per shipment and volume.

21

Transportation costs

Transportation costs for the three months ended June 30, 2018 were $528.0 million, an increase of 35.9% from $388.5 million in the comparable period of 2017. The 8.4% growth in the total number of shipments and the 25.3% increase in carrier rates per load drove the increase in our transportation costs during this period. Our transportation costs as a percentage of revenue increased to 83.2% for the three months ended June 30, 2018 from 82.6% in the comparable period of 2017, which is due to margin compression resulting from higher carrier rates.

Net revenue

Net revenue for the three months ended June 30, 2018 was $106.8 million, an increase of 30.8% from $81.6 million in the comparable period of 2017. The increase in net revenue was driven by the 24.5% increase in revenue per shipment and the 8.4% growth in the total number of shipments. Net revenue margins decreased to 16.8% for the three months ended June 30, 2018, from 17.4% in the comparable period of 2017. The decline in margin was due to the 25.3% increase in carrier rates.

Operating expenses

Commission expense for the three months ended June 30, 2018 was $32.4 million, an increase of 30.8% from $24.7 million in the comparable period of 2017, due to higher net revenue resulting from increased volume. For the three months ended June 30, 2018 and 2017, commission expense remained consistent at 30.3% of net revenue.

Selling, general and administrative expenses for three months ended June 30, 2018 were $52.2 million, an increase of 15.4% from $45.3 million in the comparable period in 2017, due to an increased investment in technology, along with the growth of our sales force and operating personnel. As a percentage of net revenue, selling, general and administrative expenses decreased to 48.9% for the three months ended June 30, 2018, from 55.5% in the comparable period of 2017. The decrease in selling, general and administrative expenses as a percent of net revenue is driven by the increase in net revenue.

The contingent consideration fair value adjustment resulted in a net expense of $0.1 million and $0.2 million for the three months ended June 30, 2018 and 2017, respectively. The net expense for 2018 was the result of adjustments made to the fair value of the contingent liabilities due to financial performance of previous acquisition owners and the time value of money. The net expense for 2017 is the result of adjustments made to the fair value of the contingent assets and liabilities due to financial performance of previous acquisition owners, time value of money and the likelihood of employee retention being met. The fair value of the contingent consideration liabilities reflects the updated probabilities and assumptions as of June 30, 2018.

Depreciation expense for the three months ended June 30, 2018 was $5.8 million, an increase of 31.6% from $4.4 million in the comparable period of 2017. The increase in depreciation expense is primarily due to depreciation of internally developed software and computer equipment.

Amortization expense for the three months ended June 30, 2018 was $3.2 million, a decrease of 9.5% from $3.6 million in the comparable period of 2017. The decrease in amortization expense was primarily attributable to the accelerated method of amortization of our acquired customer relationships along with the complete amortization of previously acquired intangible assets.

Income from operations

Income from operations for the three months ended June 30, 2018 was $13.1 million, compared to $3.4 million in the comparable period of 2017. The increase in income from operations was primarily due to higher net revenue.

Interest expense

Interest expense was $3.8 million for the three months ended June 30, 2018, an increase from $3.7 million in the comparable period of 2017. The interest expense in both years primarily relates to our Notes and the ABL Facility.

Income tax expense

We recognized income tax expense of $1.7 million and $0.0 million for the three months ended June 30, 2018 and 2017, respectively. Our effective tax rate for the three months ended June 30, 2018 was 17.9%, compared to an effective tax rate of 2.7% in the comparable period of 2017. The difference in our effective tax rate for the three months ended June 30, 2018 from the statutory federal tax rate of 21% was primarily due to tax benefits associated with stock-based compensation exercises. The

22

difference in our effective tax rate for the the three months ended June 30, 2017 from the Company's statutory federal tax rate of 35% was primarily due to net tax deficiencies related to share-based payment awards and the lower income before taxes during the quarter.

Net income (loss)

Net income for the three months ended June 30, 2018 was $7.7 million, compared to a net loss of $0.2 million in the comparable period of 2017, due to the items previously discussed.

Comparison of the six months ended June 30, 2018 and 2017

Revenue

Revenue for the six months ended June 30, 2018 was $1.2 billion, an increase of 36.8% from $0.9 billion in the comparable period of 2017. The increase in revenue was primarily attributable to an increase of 24.3% in revenue per shipment, along with an increase of 10.1% in volume.

Revenue from Transactional clients for the six months ended June 30, 2018 was $955.9 million, an increase of 35.7% from $704.4 million in the comparable period of 2017. The increase in Transactional revenue was driven by an increase in both TL and LTL revenue per shipment. Revenue from Transactional clients was 78.9% of our revenue for the six months ended June 30, 2018, a decrease from 79.5% of our revenue in the comparable period of 2017. The decrease in Transactional revenue as a percent of total revenue was driven by an increase in Managed Transportation volume.

Revenue from Managed Transportation clients for the six months ended June 30, 2018 was $256.0 million, an increase of 41.1% from $181.5 million in the comparable period of 2017. Revenue from Managed Transportation clients was 21.1% of our revenue for the six months ended June 30, 2018, an increase from 20.5% of revenue in the comparable period of 2017. This increase was driven by the addition of new clients, along with an increase in revenue from existing clients.

Transportation costs

Transportation costs for the six months ended June 30, 2018 were $1.0 billion, an increase of 37.7% from $0.7 billion in the comparable period of 2017. The 10.1% growth in the total number of shipments and the 25.1% increase in carrier rates per load drove the increase in our transportation costs during this period. Our transportation costs as a percentage of revenue increased to 82.9% for the six months ended June 30, 2018 from 82.4% in the comparable period of 2017, which is due to margin compression resulting from higher carrier rates.

Net revenue

Net revenue for the six months ended June 30, 2018 was $206.7 million, an increase of 32.4% from $156.1 million in the comparable period of 2017. The increase in net revenue was driven by the 24.3% increase in revenue per shipment and the 10.1% growth in the total number of shipments. Net revenue margins decreased to 17.1% for the six months ended June 30, 2018, from 17.6% in the comparable period of 2017. The decline in margin was due to the 25.1% increase in carrier rates, along with higher growth in our Managed Transportation business.

Operating expenses

Commission expense for the six months ended June 30, 2018 was $62.6 million, an increase of 32.8% from $47.1 million in the comparable period of 2017, due to higher volume. For the six months ended June 30, 2018 and 2017, commission expense was 30.3% and 30.2%, respectively, of net revenue. The slight increase in commission expense as a percentage of net revenue was due to the fluctuation in the composition of our net revenue by mode, as TL shipments typically have higher commission percentages than other modes.

Selling, general and administrative expenses for six months ended June 30, 2018 were $102.5 million, an increase of 13.8% from $90.0 million in the comparable period in 2017, due to an increased investment in technology, along with the growth of our sales force and operating personnel. As a percentage of net revenue, selling, general and administrative expenses decreased to 49.6% for the six months ended June 30, 2018, from 57.7% in the comparable period of 2017. The decrease in selling, general and administrative expenses as a percent of net revenue is driven by the increase in net revenue.

23

The contingent consideration fair value adjustment resulted in net expense of $0.1 million and $0.3 million for six months ended June 30, 2018 and 2017, respectively. The net expense for 2018 was the result of adjustments made to the fair value of the contingent liabilities due to financial performance of previous acquisition owners and the time value of money. The net expense for 2017 is the result of adjustments made to the fair value of the contingent assets and liabilities due to financial performance of previous acquisition owners, time value of money and the satisfaction of the employee retention criteria being met. The fair value of the contingent consideration liabilities reflects the updated probabilities and assumptions as of June 30, 2018.

Depreciation expense for the six months ended June 30, 2018 was $11.5 million, an increase of 29.2% from $8.9 million in the comparable period of 2017. The increase in depreciation expense is primarily due to depreciation of internally developed software, computer equipment and additional leasehold improvements.

Amortization expense for the six months ended June 30, 2018 was $6.5 million, a decrease of 9.4% from $7.1 million in the comparable period of 2017. The decrease in amortization expense was primarily attributable to the accelerated method of amortization of our acquired customer relationships along with the complete amortization of previously acquired intangible assets.

Income from operations

Income from operations for the six months ended June 30, 2018 was $23.6 million, compared to $2.7 million in the comparable period of 2017. The increase in income from operations was primarily due to higher net revenue.

Interest expense

Interest expense was $7.5 million for the six months ended June 30, 2018, an increase from $7.3 million of interest expense in the comparable period of 2017. The interest expense in both years primarily relates to our Notes and the ABL Facility.

Income tax (expense) benefit

We recognized income tax expense of $3.7 million and income tax benefit of $1.5 million for the six months ended June 30, 2018 and 2017, respectively. Our effective tax rate for the six months ended June 30, 2018 was 23.0%, compared to an effective tax rate of (32.8)% in the comparable period of 2017. The difference in our effective tax rate for the six months ended June 30, 2018 from the statutory federal tax rate of 21% was primarily due to state taxes; an increase in non-deductible expenses, primarily stock-based compensation; offset in part by the impact of certain tax credits. The difference in our effective tax rate for the six months ended June 30, 2017 from the Company's statutory federal tax rate of 35% was primarily due to net tax deficiencies related to share-based payment awards, completion of a state tax audit and the effect of the 2017 year to date pre-tax loss.

Net income (loss)

Net income for the six months ended June 30, 2018 was $12.4 million, compared to a net loss of $3.1 million in the comparable period of 2017, due to the items previously discussed.

Liquidity and Capital Resources

As of June 30, 2018, we had $44.7 million in cash and cash equivalents, $143.5 million in working capital and $199.3 million available under our ABL Facility.

Cash provided by operating activities

During the six months ended June 30, 2018 and 2017, net cash provided by operating activities was $34.7 million and $25.1 million, respectively. We generated $42.3 million and $23.5 million in cash from net income (adjusted for noncash operating items) for the six months ended June 30, 2018 and 2017, respectively. This cash flow generation was offset by $7.7 million in the current year and increased by $1.6 million in the same period of 2017, due to changes in working capital. These fluctuations in working capital were primarily driven by the timing of payments made and received each year.

24

Cash used in investing activities

During the six months ended June 30, 2018 and 2017, net cash used in investing activities was $14.2 million and $9.5 million, respectively. During the six months ended June 30, 2018, the primary investing activities were the internal development of computer software and the purchases of property and equipment, leasehold improvements and investments. During the six months ended June 30, 2017, the primary investing activities were the purchases of property and equipment, leasehold improvements and the internal development of computer software.

Cash provided by (used in) financing activities

During the six months ended June 30, 2018 and 2017, net cash provided by financing activities was $0.7 million, net cash used in financing activities was $12.2 million, respectively. During the six months ended June 30, 2018, the primary financing activities were the payment of contingent consideration and the use of cash to satisfy employee tax withholdings upon the vesting of equity-based awards, offset by the proceeds from the exercise of stock options. During the six months ended June 30, 2017, the primary financing activities were the purchases of treasury stock, payments and receipt of contingent consideration and the use of cash to satisfy employee tax withholdings upon the vesting of equity-based awards. We also drew $12.0 million and $32.0 million on our ABL Facility during the six months ended June 30, 2018 and 2017, respectively, all of which was repaid as of June 30, 2018 and 2017.

ABL Facility

On June 1, 2015, we entered into a Revolving Credit and Security Agreement with PNC Bank (the "Credit Agreement"). The Credit Agreement provides for a senior secured revolving credit facility in an initial aggregate principal amount of up to $200 million. Our obligations under the ABL Facility are secured, on a first lien priority basis, by certain working capital assets. We are required to pay a commitment fee in respect of the unutilized commitments under the revolving credit facility.

At June 30, 2018, there was no outstanding balance on the ABL Facility. The issuance of letters of credit under the ABL Facility also reduces available borrowings. At June 30, 2018, there were $0.7 million of letters of credit outstanding. The total draw allowed under the ABL Facility at June 30, 2018, as determined by the working capital assets pledged as collateral, was $200.0 million. After adjusting for the letters of credit, our remaining availability under the ABL Facility at June 30, 2018 was $199.3 million.

Anticipated uses of cash

Our priority is to continue to grow our revenue and net revenue. We anticipate that our operating expenses and planned expenditures will constitute material uses of cash, and we expect to use available cash to expand our sales force, to enhance our technology, to acquire or make strategic investments in complementary businesses, and for working capital and other general corporate purposes.

In 2018, we also expect to use $2.9 million to satisfy the semi-annual Notes coupon payment due November 1, 2018, as well as $11 million to $15 million for capital expenditures for the remainder of 2018. We expect our use of cash for working capital purposes and other purposes to be offset by the cash flow generated from operating activities during the same period.

Historically, our average accounts receivable life-cycle has been longer than our average accounts payable life-cycle, meaning that we have used cash to pay carriers in advance of collecting from our clients. We elect to provide this benefit to foster strong relationships with our clients and carriers. As our business grows, we expect this use of cash to continue. The amount of cash we use will depends on the growth of our business.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements.

Recent Accounting Pronouncements

The discussion of recent accounting pronouncements in Note 2, Recent Accounting Pronouncements, to the Consolidated Financial Statements (Unaudited) included in this Quarterly Report on Form 10-Q is incorporated herein by reference.

Changes in Critical Accounting Policies

We adopted Accounting Standards Codification Topic 606 Revenue from Contracts with Customers ("ASC Topic 606") on January 1, 2018. Results for reporting periods beginning on or after January 1, 2018 are presented under ASC Topic 606, of which prior amounts are not adjusted and continue to be reported in accordance with the accounting standards in effect for those periods. The changes to our revenue recognition policy under the new standard are discussed in Note 3, Revenue, to the Consolidated Financial Statements (Unaudited) included in this Quarterly Report on Form 10-Q is incorporated herein by reference.

Item 3.    Quantitative and Qualitative Disclosures About Market Risk

Commodity Risk

We pass through fluctuations in fuel prices to our clients. As a result, we believe that there is no material risk exposure to fluctuations in fuel prices.

Interest Rate Risk

We have exposure to changes in interest rates on our ABL Facility. Borrowings bear interest at one of the following, plus an applicable margin: (1) the federal funds rate, (2) the base commercial lending rate of PNC Bank, or (3) the LIBOR rate, based on the Company's election for each tranche of borrowing. The interest rate on our line of credit fluctuates based on the rates described above. Assuming the $200.0 million ABL Facility was fully drawn, a 1.0% increase in the interest rate selected would increase our annual interest expense by $2.0 million.

Our interest income is sensitive to changes in the general level of U.S. interest rates, in particular because all of our investments are in cash equivalents. Due to the short-term nature of our investments, we believe that there is no material risk exposure.

We do not use derivative financial instruments for speculative trading purposes.

Impact of Inflation

We believe that our results of operations are not materially impacted by moderate changes in the inflation rate. Inflation and changing prices did not have a material impact on our operations for the six months ended June 30, 2018 and 2017.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of June 30, 2018. The term "disclosure controls and procedures," as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of June 30, 2018, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, the Company's disclosure controls and procedures were effective at the reasonable assurance level.

Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Our internal control system was designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the consolidated financial statements for external purposes in accordance with generally accepted accounting principles. Based on its evaluation, management concluded that our internal control over financial reporting was effective as of June 30, 2018.

Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarterly period ended June 30, 2018 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Basis of Presentation

The consolidated financial statements include the accounts of Echo Global Logistics, Inc. and its subsidiaries (the "Company" or "Echo"). All significant intercompany accounts and transactions have been eliminated in the consolidation. The consolidated statements of operations include the results of entities or assets acquired from the effective date of the acquisition for accounting purposes.

The preparation of the consolidated financial statements is in conformity with the rules and regulations of the Securities and Exchange Commission ("SEC") and accounting principles generally accepted in the United States ("U.S. GAAP") for interim financial information. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules or regulations. In the opinion of management, the accompanying unaudited financial statements reflect all adjustments considered necessary for a fair presentation of the results for the period and those adjustments are of a normal recurring nature. The operating results for the six months ended June 30, 2018 are not necessarily indicative of the results expected for the full year 2018. These interim consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's audited financial statements for the year ended December 31, 2017.

Preparation of Financial Statements and Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results can differ from those estimates.

Fair Value of Financial Instruments

The carrying values of the Company's financial instruments, which consist of cash and cash equivalents, accounts receivable and accounts payable, approximate their fair values due to their short-term nature. The fair value of the due to seller liabilities are determined based on the likelihood of the Company making contingent earn-out payments (see Note 4). The fair value of the liability component of the Notes (as defined in Note 11) was determined using the discounted cash flow analysis discussed in Note 11.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

Recent Accounting Pronouncements

Recent Accounting Pronouncements

Recently adopted accounting pronouncements

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers, to clarify the principles used to recognize revenue for all entities. This new standard requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled for those goods or services. In addition, the new standard requires enhanced qualitative and quantitative disclosures related to the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers.

The Company adopted this standard on January 1, 2018 using the modified retrospective approach. As a result of using this approach, the Company recognized the cumulative effect adjustment to the opening balance of retained earnings. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods.

The adoption of this new standard adjusted the revenue recognition timing of the Company's brokerage and transportation management services performance obligation from point in time to over time on a relative transit time basis, which resulted in a cumulative transition adjustment to the opening balance of retained earnings, on January 1, 2018, of $1.1 million, net of tax, and an increase of $3.3 million to revenue for the six months ended June 30, 2018. While adoption of this standard also effects the corresponding direct costs of revenue, including commission, this change did not have a material impact on the Company's consolidated financial statements due to the short term nature of its performance obligations. The Company fully describes the adoption and impact of this standard in Note 3 to the consolidated financial statements. As part of the adoption of this standard, the Company implemented changes to its accounting policies, practices and internal controls over financial reporting.

In March 2018, the FASB issued ASU 2018-05, Income Taxes, to clarify the accounting implications of Staff Accounting Bulletin No. 118 ("SAB 118"). SAB 118 provides a measurement period that should not extend beyond one year from December 22, 2017, the date of the enactment of the Tax Cuts and Jobs Act (the "Act"), to complete the accounting under Accounting Standards Codification ("ASC") 740, Income Taxes. As of June 30, 2018, the Company has not adjusted the provisional estimate of $8.9 million recorded as a decrease to the net deferred tax liability at December 31, 2017. The Company expects to complete its analysis within the measurement period in accordance with SAB 118.

In May 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation, to provide guidance regarding which changes to a share-based payment award require modification accounting in Topic 718. The Company adopted this standard prospectively on January 1, 2018. The impact of this new standard is dependent on future modifications, if any, to the Company's share-based payment awards. For the six months ended June 30, 2018, the adoption of this standard had no impact on the consolidated financial statements.

In January 2017, the FASB issued ASU 2017-01, Business Combinations: Clarifying the Definition of a Business, to clarify the definition of a business to assist entities when evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The Company adopted this standard prospectively on January 1, 2018. The impact of this new standard is dependent on future acquisitions. For the six months ended June 30, 2018, the adoption of this standard did not have an impact on the consolidated financial statements as no acquisitions took place during the quarter.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows,to clarify the classification of certain cash receipts and cash payments in the statement of cash flows, including debt prepayment or extinguishment costs and settlement of contingent consideration arising from an acquisition. The Company adopted this standard on January 1, 2018, using the full retrospective method (prior periods have been restated). For the six months ended June 30, 2018 and 2017, cash payments in excess of the contingent consideration liability recognized at the acquisition date were recorded as an operating activity in the consolidated statements of cash flows.

Recently issued accounting pronouncements not yet adopted

In June 2018, the FASB issued ASU 2018-07, Compensation - Stock Compensation, which expands the scope of Topic 718 to include all share-based payment transactions for acquiring goods and services from nonemployees. The amendments in this update will be effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. The Company is evaluating the effects that the adoption of this guidance will have on its consolidated financial statements.

In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other: Simplifying the Test for Goodwill Impairment, to simplify the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. This new accounting standard will be effective for annual periods beginning after December 15, 2019. Early adoption is permitted. The Company is evaluating the effects that the adoption of this guidance will have on its consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases, requiring a lessee to record, on the balance sheet, the assets and liabilities for the right-of-use assets and lease obligations created by leases with lease terms of more than 12 months. This new accounting standard will be effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. The original guidance required application on a modified retrospective basis with respect to the earliest period presented. During March 2018, the FASB approved amendments to create an optional transition method that will provide an option to use the effective date of ASC 842, Leases, as of the date of initial application of the transition. The Company plans to adopt this optional transition standard on January 1, 2019. Upon adoption, the Company plans to use the package of practical expedients that allows it to (i) not reassess whether an arrangement contains a lease, (ii) carry forward its lease classification as operating or capital leases and (iii) not reassess its previously recorded initial direct costs. Adoption will also require enhanced qualitative and quantitative disclosures. The Company anticipates that the adoption of this standard will materially affect its consolidated balance sheets.

Adoption of ASC Topic 606, "Revenue from Contracts with Customers"

On January 1, 2018, the Company adopted ASU 2014-09, Revenue from Contracts with Customers ("ASC Topic 606"), using the modified retrospective method. Results for reporting periods beginning on or after January 1, 2018 are presented under ASC Topic 606; however, prior period amounts are not adjusted and continue to be reported in accordance with the accounting standards in effect for those periods.

The Company recorded an increase to the opening balance of retained earnings of $1.1 million, net of tax, as of January 1, 2018 due to the cumulative impact of adoption of ASC Topic 606. The impact to revenue for the six months ended June 30, 2018 was an increase of $3.3 million, as a result of applying ASC Topic 606.

Revenue is recognized when control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration the Company expects to receive in exchange for its services. The Company generates revenue from two different client types: Transactional and Managed Transportation. Most clients are categorized as Transactional clients. For the Transactional business, the Company provides brokerage and transportation management services on a shipment-by-shipment basis. Carrier selection, dispatch, load management and tracking are integrated services that occur within the brokerage and transportation management performance obligation. For the brokerage and transportation management performance obligation, revenue is recognized as the client's shipment travels from origin to destination by a third-party carrier. The Company is the principal in these transactions and recognizes revenue on a gross basis on a relative transit time basis. The Company categorizes a client as a Managed Transportation client if there is an agreement with the client for the provision of services, typically for a multi-year term. Brokerage and transportation management services can also be performance obligations for the Company's Managed Transportation clients. Other performance obligations for Managed Transportation clients may include transportation management services, which includes the integrated services of dispatch, tracking and carrier payment. For these types of transactions, revenue is recorded on a net basis as we do not have latitude in carrier selection or establish rates with the carrier. The Company also performs project-based services, such as compliance management, customized re-billing services and freight studies for certain Managed Transportation clients.

The following table presents the Company's revenue disaggregated by client type (in thousands, unaudited):

Variable Consideration

Certain customers may receive rebates based on the terms of their agreement with the Company, which are accounted for as variable consideration. Rebates are estimated based on the expected amount to be provided to customers and reduce revenue recognized. The Company also estimates for possible additional fees based on a portfolio approach.

Practical Expedients

The Company adopted the practical expedient to recognize commission expense when incurred because the amortization period is less than one year. Commission expense recognition aligns with the Company's revenue recognition policy under ASC Topic 606, as commission expense is recognized on a relative transit time basis.

The Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed.

Fair Value Disclosures [Abstract]

Fair Value Measurement

Fair Value Measurement

The Company applies ASC Topic 820, Fair Value Measurements and Disclosures ("ASC Topic 820"), for its financial assets and financial liabilities. The guidance requires disclosures about assets and liabilities measured at fair value. The Company's financial liabilities primarily relate to contingent earn-out payments due to sellers in connection with various acquisitions. The fair value of the due to seller liabilities at June 30, 2018 was $1.3 million. The potential earn-out payments and performance periods are defined in the individual purchase agreements for each acquisition. Earnings before interest, taxes, depreciation and amortization ("EBITDA") is the performance target defined and measured to determine the earn-out payment due, if any, after each defined measurement period.

The Company's financial assets related to contingent payments that were due from the seller of Command Transportation, LLC ("Command") based upon certain employee retention criteria. As of June 30, 2018, there was no remaining balance of the due from seller asset as the criteria were met.

ASC Topic 820 includes a fair value hierarchy that is intended to increase consistency and comparability in fair value measurements and related disclosures. The fair value hierarchy is based on observable or unobservable inputs to valuation techniques that are used to measure fair value. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources while unobservable inputs reflect a reporting entity's pricing based upon its own market assumptions. The fair value hierarchy consists of the following three levels:

• Level 1: Inputs are quoted prices in active markets for identical assets or liabilities.

• Level 2: Inputs are quoted prices for similar assets or liabilities in an active market, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs other than quoted prices that are observable and market-corroborated inputs, which are derived principally from or corroborated by observable market data.

• Level 3: Inputs that are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable.

The significant inputs used to derive the fair value of the amounts due to seller include financial forecasts of future operating results, the probability of reaching the forecast and an appropriate discount rate for each contingent liability. Probabilities are estimated by reviewing financial forecasts and assessing the likelihood of reaching the required performance measures based on factors specific to each acquisition as well as the Company’s historical experience with similar arrangements. If an acquisition reaches the required performance measure, the estimated probability would be increased to 100% and would still be classified as a contingent liability on the balance sheet. If the measure is not reached, the probability would be reduced to reflect the amount earned, if any, depending on the terms of the agreement. Discount rates used in determining the fair value of the contingent consideration due to seller ranged from 5% to 6%. Historical results of the respective acquisitions serve as the basis for the financial forecasts used in the valuation.

Quantitative factors are also considered in these forecasts, including acquisition synergies, growth and sales potential and potential operational efficiencies gained. Changes to the significant inputs used in determining the fair value of the contingent consideration due to seller could result in a change in the fair value of the contingent consideration. However, the correlation and inverse relationship between higher projected financial results to the discount rate applied and probability of meeting the financial targets mitigates the effect of any changes to the unobservable inputs.

The following tables set forth the Company's financial liabilities measured at fair value on a recurring basis and the basis of measurement at June 30, 2018 and December 31, 2017 (in thousands):

	Fair Value Measurements as of June 30, 2018

The following table provides a reconciliation of the beginning and ending balances for the liabilities measured at fair value using significant unobservable inputs (Level 3) (in thousands):

	Due to Seller Liability
Balance at December 31, 2017	$	(2,075	)
Change in fair value of contingent consideration due to seller	(100		)
Payment of contingent consideration due to seller	925
Balance at June 30, 2018	$	(1,250	)

For the three months ended June 30, 2018 and 2017, the Company recognized net expense of $50 thousand and $194 thousand, respectively, in selling, general and administrative expenses due to the change in fair value determined by a Level 3 valuation technique. For the six months ended June 30, 2018 and 2017, the Company recognized net expense of $100 thousand and $286 thousand, respectively. These changes in fair value resulted from using revised forecasts that took into account the most recent performance at each acquired business, the effect of the time value of money and the satisfaction of the employee retention criteria.

During the six months ended June 30, 2018 and 2017, the Company made contingent earn-out payments of $925 thousand and $695 thousand, respectively, to the sellers of businesses acquired by the Company. The Company did not receive any contingent payments from the seller of Command during the six months ended June 30, 2018. The Company received $500 thousand of contingent payments from the seller of Command during the six months ended June 30, 2017.

Income Taxes

Income Taxes     

On December 22, 2017, the Act was signed into legislation. The Act became effective January 1, 2018 and reduced the federal corporate tax rate from 35% to 21%.

In March 2018, the FASB issued ASU 2018-05, Income Taxes, which provides guidance on accounting for the tax effects of SAB 118, as discussed in Note 2. SAB 118 provides a measurement period that should not extend beyond one year from December 22, 2017 to complete the accounting under the Act. As of June 30, 2018, the Company has not adjusted the provisional estimate of $8.9 million recorded as a decrease to the net deferred tax liability at December 31, 2017. The Company considers the deferred tax re-measurements, and other items to be reasonable estimates, but provisional, due to the forthcoming guidance and its ongoing analysis of final year-end data and tax provisions. The Company expects to complete its analysis within the measurement period in accordance with SAB 118.

The following table shows the Company's effective income tax rate for the three and six months ended June 30, 2018 and 2017 (in thousands):

	Three Months Ended June 30,						Six Months Ended June 30,
	2018			2017			2018			2017
Income (Loss) before provision for income taxes	$	9,358		$	(239	)	$	16,107		$	(4,640	)
Income tax (expense) benefit	$	(1,680	)	$	(6	)	$	(3,702	)	$	1,523
Effective tax rate	17.9		%	2.7		%	23.0		%	(32.8		)%

The difference in the Company's effective tax rate for the three months ended June 30, 2018 from the Company's statutory federal tax rate of 21% was primarily due to tax benefits associated with stock-based compensation exercises, while the difference in the Company's effective tax rate for the six months ended June 30, 2018 from the Company's statutory federal tax rate was primarily due to state taxes; an increase in non-deductible expenses, primarily executive stock-based compensation; offset in part by the impact of certain tax credits.

The difference in the Company's effective tax rate for the three months ended June 30, 2017 from the company's federal tax rate of 35% was primarily due to net tax deficiencies related to share-based payment awards recognized as income tax expense in accordance with ASU 2016-09, Compensation - Stock Compensation: Improvements to Employee Share-Based Payment Accounting and lower income before taxes during the quarter, while the difference in the Company's effective tax rate for the six months ended June 30, 2017 was primarily due to the net tax deficiencies related to share-based payment awards, completion of a state tax audit and the effect of the 2017 year to date pre-tax loss.

Earnings Per Share [Abstract]

Earnings (Loss) Per Share

Earnings (Loss) Per Share

Basic earnings (loss) per common share is calculated by dividing net income (loss) by the weighted average number of common shares outstanding. Diluted earnings (loss) per common share is calculated by dividing net income (loss) by the weighted average shares outstanding plus share equivalents that would arise from the exercise of share options and the vesting of restricted stock and performance shares. The computation of basic and diluted earnings (loss) per common share for the three and six months ended June 30, 2018 and 2017 is as follows (in thousands, except share and per share data):

	Three Months Ended June 30,					Six Months Ended June 30,

Effect of dilutive securities:
Employee stock awards	268,850		—			332,249		—
Denominator for dilutive earnings (loss) per common share	27,871,946		28,016,122			27,798,938		28,085,710

Diluted earnings (loss) per common share	$	0.28	$	(0.01	)	$	0.45	$	(0.11	)

For the three and six months ended June 30, 2018, the Company excluded 2,538 unvested performance and market-based shares from the calculation of diluted earnings per common share because the effect was anti-dilutive. There were no employee stock options and no unvested restricted stock excluded from the calculation of diluted earnings per common share. For the three and six months ended June 30, 2017, 239,440 and 331,618 incremental shares related to stock-based awards were not included in the computation of diluted loss per common share because of the net loss during the respective periods.

As of June 30, 2018, none of the conditions allowing holders of the Notes to convert have been met and no conversion spread exists. As such, the Notes did not have a dilutive impact on diluted earnings (loss) per common share for the three and six months ended June 30, 2018 and 2017, respectively.

Long-Term Debt

Long-Term Debt

ABL Facility

On June 1, 2015, the Company and Command, as co-borrowers, entered into a Revolving Credit and Security Agreement (the “Credit Agreement”) with PNC Bank. The Credit Agreement provides for a senior secured revolving credit facility in an initial aggregate principal amount of up to $200 million (the “ABL Facility”). The Company's obligations under the ABL facility are secured, on a first lien priority basis, by certain working capital assets. The initial aggregate principal amount under the ABL Facility may be increased from time to time by an additional $100 million to a maximum aggregate principal amount of $300 million.

Interest is payable at a rate per annum equal to, at the option of the Company, any of the following, plus, in each case, an applicable margin: (a) a base rate determined by reference to the highest of (1) the federal funds effective rate, plus 0.50%, (2) the base commercial lending rate of PNC Bank, National Association and (3) a daily LIBOR rate, plus 1.00%; or (b) a LIBOR rate determined by reference to the costs of funds for deposits in the relevant currency for the interest period relevant to such borrowing adjusted for certain additional costs. The applicable margin is 0.25% to 0.75% for borrowings at the base rate and 1.25% to 1.75% for borrowings at the LIBOR rate, in each case, based on the excess availability under the ABL Facility.

The Company is required to pay a commitment fee in respect to the unutilized commitments under the revolving credit facility. At June 30, 2018, the Company's commitment fee was calculated at a rate of 0.375%. The Company recognized interest expense related to the commitment fee and borrowings on the ABL Facility of $0.2 million for each of the three months ended June 30, 2018 and 2017, and $0.4 million and $0.5 million for each of the six months ended June 30, 2018 and 2017, respectively.

The Company drew $12.0 million and $32.0 million on the ABL Facility during the six months ended June 30, 2018 and 2017, respectively, all of which was repaid as of June 30, 2018 and 2017. No amounts were outstanding on the ABL Facility as of June 30, 2018. The Company is in compliance with all covenants related to the ABL Facility.

The issuance of letters of credit under the ABL Facility reduces available borrowings. At June 30, 2018, there were $0.7 million of letters of credit outstanding. The total draw allowed on the ABL Facility at June 30, 2018, as determined by the working capital assets pledged as collateral, was $200.0 million. After adjusting for the letters of credit, the Company's remaining availability under the ABL Facility at June 30, 2018 was $199.3 million.

The Company incurred issuance costs of $3.1 million in 2015 related to the ABL Facility. These issuance costs are being amortized to interest expense using straight-line amortization over the 5 year life of the ABL Facility. For each of the three and six months ended June 30, 2018 and 2017, the Company recorded $0.2 million and $0.4 million of interest expense related to ABL Facility issuance costs, respectively. As there is no outstanding draw on the ABL Facility at June 30, 2018, the unamortized issuance costs are presented as a deferred asset on the consolidated balance sheets.

Convertible Senior Notes

On May 5, 2015, the Company issued $230 million aggregate principal amount of 2.50% convertible senior notes due 2020 (the “Notes”). The Company used all of the net proceeds from the note offering (together with the proceeds from the sale of common stock and borrowings under the ABL Facility) to finance the acquisition of Command in June 2015.

The Notes bear interest at a rate of 2.50% per year payable semiannually in arrears in cash on May 1 and November 1 of each year, beginning on November 1, 2015. The Notes will mature on May 1, 2020, unless earlier converted or repurchased in accordance with the terms discussed below. The Notes are the Company's senior unsecured obligations and rank senior in right of payment to any of the Company's indebtedness that is expressly subordinated in right of payment to the Notes; equal in right of payment to any of the Company's unsecured indebtedness that is not so subordinated; effectively junior in right of payment to any of the Company's secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities (including trade payables) of the Company's subsidiaries.

The Notes will be convertible, under certain circumstances and during certain periods, into cash, shares of the Company's common stock, or a combination of cash and shares of common stock at the Company's election, at an initial conversion rate of 25.5428 shares of common stock per $1,000 principal amount of Notes, which is equivalent to an initial conversion price of approximately $39.15 per share of common stock.

The Company's intent and policy will be to settle the $230 million principal amount of Notes in cash, and any excess conversion premium in shares of common stock. As such, the principal amount of the Notes will not be included in the calculation of diluted earnings (loss) per common share, but any conversion premium that exists will be included in the calculation of diluted earnings (loss) per common share using the treasury stock method. As of June 30, 2018, none of the conditions allowing holders of the Notes to convert have been met and no conversion spread exists. As such, the Notes did not have a dilutive impact on diluted earnings (loss) per common share for each of the six months ended June 30, 2018 and 2017.

At issuance, the Company estimated the straight debt borrowing rates at issuance to be 5.75% for similar debt to the Notes without the conversion feature, which resulted in a fair value of the liability component of $198.5 million and a fair value of the equity component of $31.5 million. The fair value of the equity component was recorded as a debt discount, with the offset recorded as a credit to additional paid-in capital within stockholders' equity. The $31.5 million debt discount and Note issuance costs discussed below are being amortized to interest expense under the effective interest method over the 5 year life of the Notes, using an effective interest rate of 6.33%.

The Company allocated the total issuance costs related to the Notes to the liability and equity components based on their relative fair values. Issuance costs attributable to the liability component were recorded on the consolidated balance sheets as a contra-liability that reduces the carrying amount of the convertible note liability. This amount is being amortized to interest expense over the term of the Notes using the effective interest method and an effective interest rate of 6.33%. Issuance costs attributable to the equity component were recorded as a charge to additional paid-in capital within stockholders' equity.

As of June 30, 2018 and December 31, 2017, the carrying amounts of the Notes on the consolidated balance sheets were calculated as follows (in thousands):

	June 30, 2018			December 31, 2017
Convertible senior notes, principal amount	$	230,000		$	230,000
Unamortized debt discount	(12,712		)	(15,930		)
Unamortized debt issuance costs	(2,514		)	(3,151		)
Convertible senior notes, net	$	214,774		$	210,919

The Notes are carried on the consolidated balance sheets at their principal amount, net of the unamortized debt discount and unamortized debt issuance costs, and are not marked to market each period. The approximate fair value of the Notes as of June 30, 2018 was $238.1 million. The fair value of the Notes was estimated based on the trading price of the Notes at June 30, 2018. As trading volume is low, these are quoted prices for identical instruments in markets that are not active, and thus are Level 2 in the fair value hierarchy.

For the three and six months ended June 30, 2018 and 2017, interest expense related to the Notes consisted of the following (in thousands):

	Three months ended June 30,				Six months ended June 30,

Accounting Policies [Abstract]

Preparation of Financial Statements and Use of Estimates

Preparation of Financial Statements and Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results can differ from those estimates.

Fair Value of Financial Instruments

Fair Value of Financial Instruments

The carrying values of the Company's financial instruments, which consist of cash and cash equivalents, accounts receivable and accounts payable, approximate their fair values due to their short-term nature. The fair value of the due to seller liabilities are determined based on the likelihood of the Company making contingent earn-out payments (see Note 4). The fair value of the liability component of the Notes (as defined in Note 11) was determined using the discounted cash flow analysis discussed in Note 11.

New Accounting Pronouncements

Recent Accounting Pronouncements

Recently adopted accounting pronouncements

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers, to clarify the principles used to recognize revenue for all entities. This new standard requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled for those goods or services. In addition, the new standard requires enhanced qualitative and quantitative disclosures related to the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers.

The Company adopted this standard on January 1, 2018 using the modified retrospective approach. As a result of using this approach, the Company recognized the cumulative effect adjustment to the opening balance of retained earnings. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods.

The adoption of this new standard adjusted the revenue recognition timing of the Company's brokerage and transportation management services performance obligation from point in time to over time on a relative transit time basis, which resulted in a cumulative transition adjustment to the opening balance of retained earnings, on January 1, 2018, of $1.1 million, net of tax, and an increase of $3.3 million to revenue for the six months ended June 30, 2018. While adoption of this standard also effects the corresponding direct costs of revenue, including commission, this change did not have a material impact on the Company's consolidated financial statements due to the short term nature of its performance obligations. The Company fully describes the adoption and impact of this standard in Note 3 to the consolidated financial statements. As part of the adoption of this standard, the Company implemented changes to its accounting policies, practices and internal controls over financial reporting.

In March 2018, the FASB issued ASU 2018-05, Income Taxes, to clarify the accounting implications of Staff Accounting Bulletin No. 118 ("SAB 118"). SAB 118 provides a measurement period that should not extend beyond one year from December 22, 2017, the date of the enactment of the Tax Cuts and Jobs Act (the "Act"), to complete the accounting under Accounting Standards Codification ("ASC") 740, Income Taxes. As of June 30, 2018, the Company has not adjusted the provisional estimate of $8.9 million recorded as a decrease to the net deferred tax liability at December 31, 2017. The Company expects to complete its analysis within the measurement period in accordance with SAB 118.

In May 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation, to provide guidance regarding which changes to a share-based payment award require modification accounting in Topic 718. The Company adopted this standard prospectively on January 1, 2018. The impact of this new standard is dependent on future modifications, if any, to the Company's share-based payment awards. For the six months ended June 30, 2018, the adoption of this standard had no impact on the consolidated financial statements.

In January 2017, the FASB issued ASU 2017-01, Business Combinations: Clarifying the Definition of a Business, to clarify the definition of a business to assist entities when evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The Company adopted this standard prospectively on January 1, 2018. The impact of this new standard is dependent on future acquisitions. For the six months ended June 30, 2018, the adoption of this standard did not have an impact on the consolidated financial statements as no acquisitions took place during the quarter.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows,to clarify the classification of certain cash receipts and cash payments in the statement of cash flows, including debt prepayment or extinguishment costs and settlement of contingent consideration arising from an acquisition. The Company adopted this standard on January 1, 2018, using the full retrospective method (prior periods have been restated). For the six months ended June 30, 2018 and 2017, cash payments in excess of the contingent consideration liability recognized at the acquisition date were recorded as an operating activity in the consolidated statements of cash flows.

Recently issued accounting pronouncements not yet adopted

In June 2018, the FASB issued ASU 2018-07, Compensation - Stock Compensation, which expands the scope of Topic 718 to include all share-based payment transactions for acquiring goods and services from nonemployees. The amendments in this update will be effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. The Company is evaluating the effects that the adoption of this guidance will have on its consolidated financial statements.

In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other: Simplifying the Test for Goodwill Impairment, to simplify the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. This new accounting standard will be effective for annual periods beginning after December 15, 2019. Early adoption is permitted. The Company is evaluating the effects that the adoption of this guidance will have on its consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases, requiring a lessee to record, on the balance sheet, the assets and liabilities for the right-of-use assets and lease obligations created by leases with lease terms of more than 12 months. This new accounting standard will be effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. The original guidance required application on a modified retrospective basis with respect to the earliest period presented. During March 2018, the FASB approved amendments to create an optional transition method that will provide an option to use the effective date of ASC 842, Leases, as of the date of initial application of the transition. The Company plans to adopt this optional transition standard on January 1, 2019. Upon adoption, the Company plans to use the package of practical expedients that allows it to (i) not reassess whether an arrangement contains a lease, (ii) carry forward its lease classification as operating or capital leases and (iii) not reassess its previously recorded initial direct costs. Adoption will also require enhanced qualitative and quantitative disclosures. The Company anticipates that the adoption of this standard will materially affect its consolidated balance sheets.
