1. Description of Business and Summary of Accounting Policies

Description of Business

Saia, Inc., and its subsidiaries (Saia or the Company), is headquartered in Johns Creek, Georgia. Saia is a leading, less-than-truckload (LTL) motor carrier with more than 96% of its revenue derived from transporting LTL shipments for customers. In addition to the core LTL services provided in 45 states, the Company also offers customers a wide range of other value-added services, including non-asset truckload, expedited transportation and logistics services across the United States.

The Chief Operating Decision Maker is the Chief Executive Officer who manages the business, regularly reviews financial information and allocates resources. The Company has one operating segment.

Basis of Presentation

The accompanying consolidated financial statements include the accounts of Saia, Inc. and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in the consolidated financial statements.

Use of Estimates

The preparation of our consolidated financial statements in conformity with U.S. generally accepted accounting principles requires the use of estimates and assumptions that affect the reported amounts of assets and liabilities and the reported amounts of revenues and expenses. Management makes its best estimate of the ultimate outcome for these items based on historical trends and other information available when the financial statements are prepared. Changes in estimates are recognized in accordance with the accounting rules for the estimate, which is typically in the period when new information becomes available to management. Areas where the nature of the estimate makes it reasonably possible that actual results could materially differ from amounts estimated include: revenue reserves; self-insurance accruals; long-term incentive compensation; tax liabilities; loss contingencies; litigation claims; and impairment assessments on long-lived assets and goodwill.

Accounting Pronouncements Adopted in 2021

In 2019, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes,” which is intended to simplify various aspects related to accounting for income taxes. This ASU removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. The Company adopted the standard effective January 1, 2021 and, upon adoption, this standard did not have a material impact on its consolidated financial statements or related disclosures.

Summary of Accounting Policies

Significant accounting policies and practices used in the preparation of the accompanying consolidated financial statements are as follows:

Cash and Cash Equivalents and Checks Outstanding: Cash and cash equivalents includes cash on hand and short term marketable securities with original maturities of three months or less.

Spare Parts, Fuel and Operating Supplies: Spare parts, fuel and operating supplies on hand are carried at average cost and are included in other current assets on the accompanying consolidated balance sheets.

Property and Equipment: Property and equipment are carried at cost less accumulated depreciation. Replacements and improvements that extend the useful life of an asset are capitalized, while repairs and maintenance that do not improve or extend the lives of the respective assets are charged to expense as incurred. The Company evaluates long-lived assets for impairment whenever events or changes in circumstances indicate the carrying value of assets may not be recoverable.

Depreciation is computed using the straight-line method, except for tractors (included in revenue equipment) for which the declining-balance method is used. The following service lives are used to compute depreciation:

	Years
Structures	20 to 25
Revenue equipment	6 to 14
Technology equipment and software	3 to 5
Other	3 to 10

At December 31, property and equipment consisted of the following (in thousands):

	2022		2021
Land	$	191,057	$	159,309
Structures		638,180		521,578
Revenue equipment		1,340,761		1,196,000
Technology equipment and software		187,333		161,791
Other		121,493		105,850
Total property and equipment, at cost	$	2,478,824	$	2,144,528

The Company’s investment in technology equipment and software consists primarily of systems to support customer service, maintenance and freight management. Depreciation and amortization expense (including amortization of assets under finance leases) was $156.2 million, $140.5 million and $133.5 million for the years ended December 31, 2022, 2021 and 2020, respectively. At December 31, 2022, trailers acquired under finance leases had a gross carrying value of $137.9 million and accumulated amortization of $58.7 million. At December 31, 2021, trailers acquired under finance leases had a gross carrying value of $137.9 million and accumulated amortization of $49.4 million.

Claims and Insurance Accruals: The Company maintains a significant amount of insurance coverage with third-party insurance carriers that provides various levels of protection for covered risk exposure, including in the areas of workers’ compensation, bodily injury and property damage, casualty, cargo loss and damage and group health, with coverage limits and retention and deductible amounts that vary based on policy periods and claim type. Claims and insurance accruals related to workers’ compensation, bodily injury and property damage, casualty, cargo loss and damage and group health are established by management based on estimates of losses that the Company will ultimately incur on reported claims and on claims that have been incurred but not yet reported. Accruals are calculated on reported claims based on an evaluation of the nature and severity of the claim, historical loss experience and on legal, economic and other factors. Actuarial analysis is also used in calculating the accruals for workers’ compensation and bodily injury and property damage claims.

Income Taxes: Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period enacted. As required by FASB Accounting Standards Codification (ASC) Topic 740, Income Taxes, the Company defines the threshold for recognizing the benefits of tax-filing positions in the financial statements as “more-likely-than-not” to be sustained by the tax authority.

Revenue Recognition: The Company’s revenues are derived primarily from the transportation of freight as it satisfies performance obligations that arise from contracts with its customers. The Company’s performance obligations arise when it receives a bill of lading (BOL) to transport a customer's commodities at negotiated prices contained in either a transportation services agreement or a publicly disclosed tariff rate. Once a BOL is received and accepted, a legally-enforceable contract is formed whereby the parties are committed to perform and the rights of the parties, shipping terms and conditions, and payment terms have been identified. Each shipment represents a distinct service that is a separately identified performance obligation.

The typical transit time to complete a shipment is from one to five days. Billing for transportation services normally occurs after completion of the service and payment is generally due within 30 days after the invoice date. The Company recognizes revenue related to the Company’s LTL, non-asset truckload and expedited transportation services over the transit time of the shipment as it moves from origin to destination based on the transit status at the end of each reporting period.

Key estimates included in the recognition and measurement of revenue and related accounts receivable are as follows:

•Revenue associated with shipments in transit is recognized ratably over transit time; and

•Adjustments to revenue for billing adjustments and collectability.

The portion of the gross invoice related to interline transportation services that involve the services of another party, such as another LTL service provider, is not recorded in the Company’s revenues. Revenue from logistics services is recognized as the services are provided.

Credit Risk: The Company routinely grants credit to its customers. The risk of significant loss in trade receivables is substantially mitigated by the Company’s credit evaluation process, short collection terms, low revenue per transaction and services performed for a large number of customers with no single customer representing more than 5 percent of accounts receivable at year-end. Allowances for potential credit losses are based on historical loss experience, current economic environment, expected trends and customer specific factors.

Stock-Based Compensation: The Company has various stock-based compensation plans for its employees and non-employee directors. The Company stock-based compensation includes awards of stock options, restricted stock awards, and stock-based compensation unit awards, all of which are accounted for under FASB ASC Topic 718, Compensation-Stock Compensation. Stock options granted to employees are valued using a Black-Scholes-Merton model with the expense amortized over the three-year vesting period. Restricted stock is valued based on the fair market value of the Company's common stock at the date of grant and the expense is amortized over the three to five year vesting period. Stock-based performance unit awards are valued using a Monte Carlo model and the expense is amortized over the three-year vesting period.

Intangible Assets: The Company tests goodwill for impairment annually and whenever events or changes in circumstance indicate that impairment may have occurred. The Company first performs a qualitative assessment to determine whether it is necessary to perform a required two-step goodwill impairment test. The Company is not required to estimate the fair value of a reporting unit unless the Company determines, based on qualitative assessment, that it is more likely than not that its fair value is less than its carrying amount. Purchased intangible assets subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.

Advertising: The costs of advertising are expensed as incurred. Advertising costs charged to expense were $7.2 million, $5.7 million, and $4.6 million in 2022, 2021 and 2020, respectively.

Financial Instruments: The carrying amounts of financial instruments including cash and cash equivalents, accounts receivable and accounts payable approximated fair value as of December 31, 2022 and 2021, because of the relatively short maturity of these instruments. See Note 2 for fair value disclosures related to debt.
