	1. Organization, Nature of Business and Significant Accounting Policies
	Nature of Business
	Roadrunner Transportation Systems, Inc. (the “Company”) is headquartered in Cudahy, Wisconsin and has the following three operating segments: truckload logistics (“TL”), less-than-truckload (“LTL”), and transportation management solutions (“TMS”). Within its TL business, the Company operates a network of 44 TL service centers, five freight consolidation and inventory management centers, and 25 company dispatch offices and is augmented by 130 independent brokerage agents. Within its LTL business, the Company operates 45 LTL service centers throughout the United States, complemented by relationships with over 180 delivery agents. Within its TMS business, the Company operates from 11 service centers and nine dispatch offices throughout the United States. From pickup to delivery, the Company leverages relationships with a diverse group of third-party carriers to provide scalable capacity and reliable, customized service, including domestic and international air and ocean transportation services, to its customers. The Company operates primarily in the United States.
	Principles of Consolidation
	The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). All intercompany balances and transactions have been eliminated in consolidation. In the Company's opinion, these financial statements include all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the operations for the interim periods presented. Interim results are not necessarily indicative of results for a full year.
	Use of Estimates
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
	Segment Reporting
	The Company determines its operating segments based on the information utilized by the chief operating decision maker, the Company’s Chief Executive Officer, to allocate resources and assess performance. Based on this information, the Company has determined that it has three operating segments, which are also its reportable segments: TL, LTL, and TMS.

	4. Fair Value Measurement
	Accounting guidance on fair value measurements for certain financial assets and liabilities requires that assets and liabilities carried at fair value be classified and disclosed in one of the following three categories:
	Level 1 — Quoted market prices in active markets for identical assets or liabilities.
	Level 2 — Observable market-based inputs or unobservable inputs that are corroborated by market data.
	Level 3 — Unobservable inputs reflecting the reporting entity’s own assumptions or external inputs from inactive markets.
	A financial asset’s or liability’s classification within the hierarchy is determined based on the lowest level of input that is significant to the fair value measurement.
	The contingent purchase price related to acquisitions is measured at fair value on a recurring basis, according to the valuation techniques the Company used to determine fair value. The following table presents information, as of September 30, 2014 and December 31, 2013, about the Company’s financial liabilities (in thousands):
		September 30, 2014
		Level 1			Level 2			Level 3			Fair Value
	Contingent purchase price related to acquisitions	$	—		$	—		$	8,555		$	8,555

	Total liabilities at fair value	$	—		$	—		$	17,054		$	17,054
	In measuring the fair value of the contingent purchase price liability, the Company used an income approach that considers the expected future earnings of the acquired businesses and the resulting contingent payments, discounted at a risk-adjusted rate.
	The table below sets forth a reconciliation of the Company’s beginning and ending Level 3 financial liability balance for the three and nine months ended September 30, 2014 and 2013 and the year ended December 31, 2013 (in thousands):

The credit agreement is collateralized by all assets of the Company and contains certain financial covenants, including a minimum fixed charge coverage ratio and a maximum cash flow leverage ratio. Additionally, the credit agreement contains negative covenants limiting, among other things, additional indebtedness, capital expenditures, transactions with affiliates, additional liens, sales of assets, dividends, investments, advances, prepayments of debt, mergers and acquisitions, and other matters customarily restricted in such agreements. As of and during the three and nine months ended September 30, 2014, the Company was in compliance with all covenants contained in the credit agreement. Borrowings under the credit agreement bear interest at either (a) the Eurocurrency Rate (as defined in the credit agreement), plus an applicable margin in the range of 2.0% to 3.0%, or (b) the Base Rate (as defined in the credit agreement), plus an applicable margin in the range of 1.0% to 2.0%. The revolving credit facility also provides for the issuance of up to $30.0 million in letters of credit. As of September 30, 2014, the Company had outstanding letters of credit totaling $18.6 million.

Earnings Per Share	'
	7. Earnings Per Share
	Basic earnings per common share is calculated by dividing net income available to common stockholders by the weighted average number of shares of common stock outstanding during the period. For the three and nine months ended September 30, 2014 and 2013, diluted earnings per share was calculated by dividing net income available to common stockholders by the weighted average common stock outstanding plus stock equivalents that would arise from the assumed exercise of stock options, the conversion of warrants, and the delivery of stock underlying restricted stock units using the treasury stock method. There is no difference, for any of the periods presented, in the amount of net income available to common stockholders used in the computation of basic and diluted earnings per share.
	As of September 30, 2014, all stock options, warrants, and restricted stock units were included in the computation of diluted earnings per share. The following table reconciles basic weighted average common stock outstanding to diluted weighted average common stock outstanding for the three and nine months ended September 30, 2014 and 2013 (in thousands):
		Three Months Ended		Nine Months Ended

	8. Income Taxes
	The effective income tax rate was 32.8% for the three months ended September 30, 2014 compared to 38.7% for the three months ended September 30, 2013. The effective tax rate was 36.7% for the nine months ended September 30, 2014 compared to 38.7% for the nine months ended September 30, 2013. In determining the provision for income taxes, the Company used an estimated annual effective tax rate, which was based on expected annual income, statutory tax rates, and the Company's best estimate of non-deductible and non-taxable items of income and expense. Income tax expense varies from the amount computed by applying the federal corporate income tax rate of 35.0% to income before income taxes primarily due to state income taxes, net of federal income tax effect, and adjustments for permanent differences.

	9. Guarantees
	The Company provides a guarantee for a portion of the value of certain independent contractors' ("IC") leased tractors.  The guarantees expire at various dates through 2020.  The potential maximum exposure under these lease guarantees was approximately $17.6 million as of September 30, 2014.  The potential maximum exposure represents the Company’s commitment on remaining lease payments on guaranteed leases as of September 30, 2014.  However, upon an IC default, the Company has the option to purchase the tractor or return the tractor to the leasing company if the residual value is greater than the Company’s guarantee. Alternatively, the Company can contract another IC to assume the lease.  There were no material IC defaults during the three and nine months ended September 30, 2014 and 2013. Payments made by the Company under the guarantees were de minimis for the three and nine months ended September 30, 2014 and 2013. No liability related to these lease guarantees was recorded as of September 30, 2014 or December 31, 2013.

Based on this information, the Company has determined that it has three operating segments, which are also its reportable segments: TL, LTL, and TMS.
	These reportable segments are strategic business units through which the Company offers different services. The Company evaluates the performance of the segments primarily based on their respective revenues and operating income. Accordingly, interest expense and other non-operating items are not reported in segment results. In addition, the Company has disclosed a corporate segment, which is not an operating segment and includes acquisition transaction expenses, corporate salaries, and share-based compensation expense.
	The following table reflects certain financial data of the Company’s reportable segments for the three and nine months ended September 30, 2014 and 2013 and as of September 30, 2014 and December 31, 2013 (in thousands):
