	Basis of Presentation
	The accompanying unaudited condensed consolidated financial statements include the accounts of Saia, Inc. and its wholly-owned subsidiaries (together, the Company or Saia). All significant intercompany accounts and transactions have been eliminated in the condensed consolidated financial statements.
	The condensed consolidated financial statements have been prepared by the Company without audit by the independent registered public accounting firm. In the opinion of management, all normal recurring adjustments necessary for a fair presentation of the condensed consolidated balance sheets, statements of operations and cash flows for the interim periods included herein have been made. These interim condensed consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information, the instructions to Quarterly Report on Form 10-Q and Rule 10-01 of Regulation S-X. Certain information and note disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles have been condensed or omitted from these statements. The accompanying condensed consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2014. Operating results for the quarter ended March 31, 2015 are not necessarily indicative of the results of operations that may be expected for the year ended December 31, 2015.
	Business
	The Company offers customers a wide range of less-than-truckload, non-asset truckload, expedited and logistics services across the United States through its wholly-owned subsidiaries. Effective February 2, 2015, the Company’s subsidiaries were as follows: Saia Motor Freight Line, LLC, doing business as Saia LTL Freight; Saia TL Plus, LLC, formerly Robart Transportation, Inc., Saia Sales, LLC, Saia Logistics Services, LLC, formerly The RL Services Group, LLC, Saia MetroGo, LLC, formed on January 22, 2015 and LinkEx, Inc. acquired on February 2, 2015.
	New Accounting Pronouncements
	On May 28, 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services. The ASU will replace most existing revenue recognition guidance in U.S. generally accepted accounting principles when it becomes effective. The new standard is effective for the Company on January 1, 2017. Early application is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU No. 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it completed its evaluation of the effect of the standard on its ongoing financial reporting.

	The carrying amounts of financial instruments including cash and cash equivalents, accounts receivable, accounts payable and other current liabilities approximated fair value as of March 31, 2015 and December 31, 2014 because of the relatively short maturity of these instruments. Based on the borrowing rates currently available to the Company for debt with similar terms and remaining maturities the estimated fair value of total debt at March 31, 2015 and December 31, 2014 was $108.3 million and $83.7 million, respectively, based upon level two in the fair value hierarchy. The carrying value of the debt was $107.6 million and $83.0 million at March 31, 2015 and December 31, 2014, respectively.

	Long-term debt, less current portion		$	98,076	$	73,897
	On March 6, 2015, the Company entered into the Fifth Amended and Restated Credit Agreement with its banking group (as amended, the Restated Credit Agreement). The amendment increased the amount of the revolver from $200 million to $250 million and extended the term until March 2020. The amendment also reduced the interest rate pricing grid, eliminated both the borrowing base and the minimum tangible net worth covenant. On the same date, the Company also entered into the Second Amended and Restated Master Shelf Agreement with its long term note holders (as amended, the Restated Master Shelf Agreement) that made changes to this agreement to conform with certain changes in the Restated Credit Agreement.
	Restated Credit Agreement
	The Restated Credit Agreement is a revolving credit facility for up to $250 million expiring in March 2020. The Restated Credit Agreement also has an accordion feature that allows for an additional $75 million availability, subject to lender approval. The Restated Credit Agreement provides for a LIBOR rate margin range from 112.5 basis points to 225 basis points, base rate margins from minus 12.5 basis points to plus 50 basis points, an unused portion fee from 20 basis points to 30 basis points and letter of credit fees from 112.5 basis points to 225 basis points in each case based on the Company’s leverage ratio.
	Under the Restated Credit Agreement, the Company must maintain certain financial covenants including a minimum fixed charge coverage ratio and a maximum leverage ratio, among others. The Restated Credit Agreement also provides for a pledge by the Company of certain land and structures, certain tractors, trailers and other personal property and accounts receivable, as defined in the Restated Credit Agreement.
	At March 31, 2015, the Company had borrowings of $66.6 million and outstanding letters of credit of $41.3 million under the Restated Credit Agreement. At December 31, 2014, the Company had borrowings of $45.0 million and outstanding letters of credit of $47.3 million under the Restated Credit Agreement. The available portion of the Restated Credit Agreement may be used for general corporate purposes, including future capital expenditures, working capital and letter of credit requirements as needed.
	Restated Master Shelf Agreement
	On September 20, 2002, the Company issued $100 million in Senior Notes under a $125 million (amended to $150 million in April 2005) Master Shelf Agreement with Prudential Investment Management, Inc. and certain of its affiliates. The Company issued another $25 million in Senior Notes on November 30, 2007 and $25 million in Senior Notes on January 31, 2008 under the same Master Shelf Agreement.
	The initial $100 million Senior Notes had a fixed interest rate of 7.38 percent. Payments due under the $100 million Senior Notes were interest only until June 30, 2006 and at that time semi-annual principal payments began with the final payment due December 2013. The November 2007 issuance of $25 million Senior Notes has a fixed interest rate of 6.14 percent. The January 2008 issuance of $25 million Senior Notes has a fixed interest rate of 6.17 percent. Payments due for both $25 million issuances were interest only until June 30, 2011 and at that time semi-annual principal payments began with the final payments due January 1, 2018. Under the terms of the Senior Notes, the Company must maintain certain financial covenants including a minimum fixed charge coverage ratio and a maximum leverage ratio, among others.
	Capital Leases
	The Company is obligated under capital leases which include obligations covering revenue equipment totaling $19.6 million with a seven year term. Amortization of assets held under the capital leases is included in depreciation expense. The weighted average interest rate for the capital leases at March 31, 2015 is 2.90%.
	The principal maturities of long-term debt instruments (in thousands) are as follows:
			Amount
	2015		$	9,358
	2016			10,097
	2017			10,097
