Restricted cash represents an amount held in a segregated bank account by Wells Fargo as collateral for amounts outstanding under our letter of credit facility. In June 2019, the amount of outstanding letters of credit under our letter of credit facility exceeded the borrowing base as defined in the letter of credit facility agreement. As a result, we were required to deposit cash with the lender as security for the outstanding letters of credit. See “Letter of Credit Facility” within this Note 2 for further information. Our borrowing base is based on our net receivable balance, and due to customer prepayments, our borrowing base as outlined in the letter of credit facility did not fully

support the outstanding letters of credit that have been issued. As a result, on July 1, 2019, we canceled the letter of credit facility, and secured the outstanding letters of credit with our restricted cash balance.

The following table provides a reconciliation of cash and cash equivalents and restricted cash as reported with the unaudited condensed consolidated balance sheet that totals to the amounts shown in the unaudited condensed consolidated statements of cash flow (in thousands):


	June 30,
	2019

Cash and cash equivalents	$	127,670
Restricted cash	4,876
Total cash, cash equivalents and restricted cash shown in the
unaudited condensed consolidated statements of cash flow	$	132,546

Basic earnings (losses) per share is computed by dividing our net earnings (losses) by the weighted average number of shares of common stock outstanding during the period. Diluted earnings (losses) per share is computed by giving effect to all potential shares of common stock outstanding, including our stock 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 10 for further discussion).

(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 performance conditions for the performance share unit awards granted in 2018 were achieved as of December 31, 2018. For the three and six months ended June 30, 2019, the effect of the performance share awards on earning per share is anti-dilutive.

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.

We maintained a Credit and Security Agreement with Wells Fargo Bank, National Association to provide for the issuance of up to $60.0 million in stand-by letters of credit primarily used to support crude oil purchases within our crude oil marketing segment and for other purposes. We used the letter of credit facility for letters of credit related to our insurance program. This facility was collateralized by the eligible accounts receivable within our crude oil marketing segment and expires on August 30, 2019.

The issued stand-by letters of credit were canceled as the underlying purchase obligations were satisfied by cash payment when due. The letter of credit facility placed certain restrictions on GulfMark Energy, Inc., one of our wholly owned subsidiaries. These restrictions included the maintenance of positive net earnings excluding inventory valuation changes, as defined, among other restrictions. At June 30, 2019 and December 31, 2018, we had $4.6 million and $4.6 million, respectively, of letters of credit outstanding under this facility. On July 1, 2019, we canceled the letter of credit facility, and secured the outstanding letters of credit with our restricted cash balance.

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 properties requiring impairment, the fair value is estimated based on an internal discounted cash flow model of future cash flows.

We measure all share-based payments, including the issuance of restricted stock units and performance share units 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 statement of operations based on the estimated fair value of those awards on the grant date and 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.
