The following table provides a reconciliation of cash and cash equivalents and restricted cash as reported in the unaudited condensed consolidated balance sheets that totals to the amounts shown in the unaudited condensed consolidated statements of cash flows at the dates indicated (in thousands):


	March 31,		December 31,
	2022		2021

Cash and cash equivalents	$	99,295	$	97,825
Restricted cash:

Captive insurance subsidiary (1)	8,850		9,492
Total cash, cash equivalents and restricted cash shown in the
unaudited condensed consolidated statements of cash flows	$	108,145	$	107,317

(1)$1.5 million of the restricted cash balance relates to the initial capitalization of our captive insurance company formed in late 2020, and the remainder represents amounts paid to our captive insurance company for insurance premiums.

Vesting of restricted stock unit awards (see Note 11)						15,966

At March 31, 2022, we had no borrowings outstanding under our $40.0 million Credit Agreement with Wells Fargo Bank, National Association (“Credit Agreement”) and $6.1 million of letters of credit issued under the Credit Agreement at a fee of 1.75 percent per annum. At March 31, 2022, we were in compliance with all covenants under the Credit Agreement.

Basic earnings (losses) per share is computed by dividing our net earnings (losses) by the weighted average number of common shares outstanding during the period. Diluted earnings (losses) per share is computed by giving effect to all potential common shares outstanding, including our shares related to unvested restricted stock unit awards. Unvested restricted stock unit awards granted under the Adams Resources & Energy, Inc. 2018 Long-Term Incentive Plan (“2018 LTIP”) are not considered to be participating securities as the holders of these shares do not have non-forfeitable dividend rights in the event of our declaration of a dividend for common shares (see Note 11 for further discussion).

A reconciliation of the calculation of basic and diluted earnings per share was as follows for the periods indicated (in thousands, except per share data):


	Three Months Ended
	March 31,
	2022		2021
Earnings per share — numerator:
Net earnings	$	6,090	$	2,808

Denominator:
Basic weighted average number of shares outstanding	4,359		4,246

Basic earnings per share	$	1.40	$	0.66

Diluted earnings per share:
Diluted weighted average number of shares outstanding:
Common shares	4,359		4,246
Restricted stock unit awards	24		18
Performance share unit awards (1)	11		7
Total diluted shares	4,394		4,271

Diluted earnings per share	$	1.39	$	0.66

(1)The dilutive effect of performance share awards are included in the calculation of diluted earnings per share when the performance share award performance conditions have been achieved.

The carrying amounts reported in the unaudited condensed consolidated balance sheets for cash and cash equivalents, accounts receivable and accounts payable approximates fair value because of the immediate or short-term maturity of these financial instruments. Marketable securities are recorded at fair value based on market quotations from actively traded liquid markets.

A three-tier hierarchy has been established that classifies fair value amounts recognized in the financial statements based on the observability of inputs used to estimate these fair values. The hierarchy considers fair value amounts based on observable inputs (Levels 1 and 2) to be more reliable and predictable than those based primarily on unobservable inputs (Level 3). At each balance sheet reporting date, we categorize our financial assets and liabilities using this hierarchy.

Fair value contracts consist of derivative financial instruments and are recorded as either an asset or liability measured at its fair value. Changes in fair value are recognized immediately in earnings unless the derivatives qualify for, and we elect, cash flow hedge accounting. We had no contracts designated for hedge accounting during any current reporting periods (see Note 10 for further information).

Income taxes are accounted for using the asset and liability method. Under this approach, deferred tax assets and liabilities are recognized based on anticipated future tax consequences attributable to differences between financial statement carrying amounts of these items and their respective tax basis.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was enacted and signed into law in response to the COVID-19 pandemic. The CARES Act, among other things, permits net operating losses (“NOL”) incurred in tax years 2018, 2019 and 2020 to offset 100 percent of taxable income and be carried back to each of the five preceding taxable years to generate a refund of previously paid income taxes.

We have determined that the NOL carryback provision in the CARES Act would result in a cash benefit to us for the fiscal year 2020. We have an income tax receivable at March 31, 2022, of approximately $6.8 million for the benefit of carrying back the NOL for the fiscal year 2020 to 2015 and 2016. As we are carrying the losses back to years beginning before January 1, 2018, the receivable was recorded at the previous 35 percent federal tax rate rather than the current statutory rate of 21 percent.

Inventory consists of crude oil held in storage tanks and at third-party pipelines as part of our crude oil marketing and pipeline and storage operations. Crude oil inventory is carried at the lower of cost or net realizable value. At the end of each reporting period, we assess the carrying value of our inventory and make adjustments necessary to reduce the carrying value to the applicable net realizable value. Any resulting adjustments are a component of marketing costs and expenses or pipeline and storage expenses on our consolidated statements of operations. No charges were recognized during the three months ended March 31, 2022 and 2021.

Property and equipment is recorded at cost. Expenditures for additions, improvements and other enhancements to property and equipment are capitalized, and minor replacements, maintenance and repairs that do not extend asset life or add value are charged to expense as incurred. When property and equipment assets are retired or otherwise disposed of, the related cost and accumulated depreciation is removed from the accounts and any resulting gain or loss is included in results of operations in operating costs and expenses for the respective period. Property and equipment, except for land, is depreciated using the straight-line method over the estimated average useful lives ranging from two to thirty-nine years.

We review our long-lived assets for impairment whenever there is evidence that the carrying value of these assets may not be recoverable. Any impairment recognized is permanent and may not be restored. Property and equipment is reviewed at the lowest level of identifiable cash flows. For property and equipment requiring impairment, the fair value is estimated based on an internal discounted cash flow model of future cash flows.

We measure all share-based payment awards, including the issuance of restricted stock unit awards and performance share unit awards to employees and board members, using a fair-value based method. The cost of services received from employees and non-employee board members in exchange for awards of equity instruments is recognized in the consolidated statements of operations based on the estimated fair value of those awards on the grant date and is amortized on a straight-line basis over the requisite service period. The fair value of restricted stock unit awards and performance share unit awards is based on the closing price of our common stock on the grant date. We account for forfeitures as they occur. See Note 11 for additional information regarding our 2018 LTIP.
