Accounting Policies [Abstract]
Business Overview and Summary of Significant Accounting Policies	Note 1. Business Overview and Summary of Significant Accounting Policies Business Overview Fastenal is a leader in the wholesale distribution of industrial and construction supplies. We distribute these supplies through a network of branches and Onsite locations. Collectively, we refer to our branches and Onsite locations as in-market locations. We have approximately 3,300 in-market locations located primarily in North America. Principles of Consolidation The consolidated financial statements include the accounts of Fastenal Company and its subsidiaries (collectively, referred to as Fastenal or by terms such as we, our, or us). All material intercompany balances and transactions have been eliminated in consolidation. Revenue Recognition Net sales include products and shipping and handling charges, net of estimates for product returns and any related sales incentives. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring products. All revenue is recognized when we satisfy our performance obligations under the contract. We recognize revenue by transferring control of the promised products to the customer, with the majority of revenue recognized at the point in time the customer obtains control of the products. We recognize revenue for shipping and handling charges at the time the products are delivered to or picked up by the customer. We estimate product returns based on historical return rates. Using probability assessments, which are based on known inputs at year-end, we estimate sales incentives expected to be paid over the term of the contract. The majority of our contracts have a single performance obligation and are short term in nature. Sales taxes and value added taxes in foreign jurisdictions that are collected from customers and remitted to governmental authorities are accounted for on a net basis and therefore are excluded from net sales. Accounts Receivable Credit is extended based upon an evaluation of the customer's financial condition. Accounts receivable are stated at their estimated net realizable value. The allowance for credit losses is based on an income statement approach which adjusts the ending balance sheet to take into consideration expected losses over the contractual lives of the receivables, considering factors such as historical data as a basis for future expected losses. Foreign Currency Translation and Transactions The functional currency of our foreign operations is typically the applicable local currency. The functional currency is translated into United States dollars for balance sheet accounts, except retained earnings, using current exchange rates as of the balance sheet date, for retained earnings at historical exchange rates, and for revenue and expense accounts using a weighted average exchange rate during the applicable period. The translation adjustments are deferred as a separate component of stockholders' equity captioned accumulated other comprehensive income (loss). Gains or losses resulting from transactions denominated in foreign currencies are included in cost of sales or operating and administrative expenses. Cash and Cash Equivalents We consider all highly liquid investments purchased with original maturities of three months or less to be cash equivalents. Inventories Inventories, consisting of finished goods merchandise held for resale, are stated at the lower of cost (first in, first out method) or net realizable value. We record valuation adjustments for excess, slow-moving, and obsolete inventory that are equal to the difference between the cost and estimated net realizable value for that inventory. These estimates are based on a review and comparison of the current inventory levels to projected and historical sales of inventory. Property and Equipment Property and equipment are stated at cost. Depreciation on property and equipment is provided for using the straight-line method over the anticipated economic useful lives of the related property. Leases We determine if an arrangement contains a lease at inception. Operating leases are included in our operating lease right-of-use (ROU) assets, the current portion of operating lease liabilities, and the operating lease liabilities in our Consolidated Balance Sheets. The ROU assets represent our right to control the use of an underlying asset for the lease term, and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. The operating lease ROU assets also include any prepaid lease payments made and exclude lease incentives. Lease expense is recognized on a straight-line basis over the lease term. Many of our leases include both lease (e.g., fixed payments including rent, taxes, and insurance costs) and non-lease components (e.g., common-area or other maintenance costs) which are accounted for as a single lease component as we have elected the practical expedient to group lease and non-lease components for all leases. Our pick-up truck leases typically have a non-cancelable lease term of less than one year and therefore, we have elected the practical expedient to exclude these short-term leases from our ROU assets and lease liabilities. Most leases include one or more options to renew. The exercise of lease renewal options is typically at our sole discretion; therefore, the majority of renewals to extend the lease terms are not included in our ROU assets and lease liabilities as they are not reasonably certain of exercise. We regularly evaluate the renewal options and when they are reasonably certain of exercise, we include the renewal period in our lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the lease commencement date in determining the present value of the lease payments. We have a centrally managed treasury function; therefore, based on the applicable lease terms and the current economic environment, we apply a portfolio approach for determining the incremental borrowing rate. Long-Lived Assets Long-lived assets consist of net property and equipment, operating lease right-of-use assets, prepaid deposits, goodwill, and definite-lived intangible assets, and are reviewed for impairment whenever an event or change in circumstance indicates that the carrying amount of the asset may not be recoverable. If circumstances require a long-lived asset or asset group be tested for possible impairment, we first compare undiscounted cash flows expected to be generated by the asset or asset group to its carrying value. If the carrying value of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent the carrying value exceeds its fair value. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market values, and third-party independent appraisals, as necessary. There were no impairments recorded during any of the three years reported in these consolidated financial statements. Goodwill represents the excess of the purchase price over the fair value of net assets acquired. Goodwill is reviewed for impairment annually. The identifiable intangible assets are amortized on a straight-line basis over their estimated life. On March 30, 2020, we purchased certain assets of Apex for $125.0, including identifiable intangible assets totaling $123.8 , with a weighted average amortization period of approximately 19.4 years. Accounting Estimates The preparation of the consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and the disclosure of contingent liabilities. Actual results could differ from those estimates. Insurance Reserves We are self-insured for certain losses relating to workers' compensation, automobile, health, and general liability costs. Specific stop-loss coverage is provided for catastrophic claims in order to limit exposure to significant claims. Self-insurance liabilities are based on our estimate of reported claims and claims incurred but not yet reported. Product Warranties We offer a basic limited warranty for certain of our products. The specific terms and conditions of those warranties vary depending upon the product sold. We typically recoup these costs through product warranties we hold with the original equipment manufacturers. Our warranty expense has historically been minimal. Stock-Based Compensation We estimate the fair value of stock options as of the date of the grant using a Black-Scholes valuation model. Stock-based compensation expense equal to the grant date fair value is recognized on a straight-line basis over the vesting period. Our stock-based compensation expense is recorded in operating and administrative expenses. Income Taxes We account for income taxes under the asset and liability method. Under this 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 that includes the enactment date. We recognize the effect of income tax positions only if those positions are more likely than not to be sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. We record interest and penalties related to unrecognized tax benefits in income tax expense. Earnings Per Share Basic net earnings per share is calculated using net earnings available to common stockholders divided by the weighted average number of shares of common stock outstanding during the year. Diluted net earnings per share is similar to basic net earnings per share except that the weighted average number of shares of common stock outstanding includes the incremental shares assumed to be issued upon the exercise of stock options considered to be 'in-the-money' (i.e., when the market price of our stock is greater than the exercise price of our outstanding stock options). Segment Reporting We have determined that for our North American regions we meet the aggregation criteria outlined in the accounting standards as these regions have similar: (1) economic characteristics, (2) products and services, (3) customers, (4) distribution channels, and (5) regulatory environments. Considering our operations outside of North America represent less than 10% of our net sales, net earnings, or assets, we report as a single business segment. Recently Issued Accounting Pronouncements In March 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting , which provides temporary optional expedients and exceptions to U.S. GAAP on contract modifications, hedging relationships, and other transactions affected by reference rate reform to ease entities' financial reporting burdens as the market transitions from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. The guidance was effective upon issuance and may be applied prospectively to contract modifications made, hedging relationships entered into, and other transactions affected by reference rate reform, evaluated on or before December 31, 2022, beginning during the reporting period in which the guidance has been elected. In December 2022, the FASB issued ASU 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848 , which extended the date to December 31, 2024. We do not have any receivables, hedging relationships, lease agreements, or debt agreements that reference LIBOR or another reference rate expected to be discontinued. On September 28, 2022, we amended and restated our unsecured revolving credit agreement. At the same time, we also amended our master note agreement. As a result of those amendments, our floating rate debt no longer references a LIBOR based benchmark rate. Therefore, we will not be electing the optional practical expedients associated with this ASU.

Stockholders' Equity Note [Abstract]
Stockholders' Equity	Note 5. Stockholders' Equity Dividends On January 18, 2023, our board of directors declared a quarterly dividend of $0.35 per share of common stock to be paid in cash on March 2, 2023 to shareholders of record at the close of business on February 2, 2023. We paid aggregate annual cash dividends per share of $1.24 and $1.12 in 2022 and 2021, respectively. In 2020, we paid aggregate annual cash dividends per share of $1.40, which included a special, one-time dividend of $0.40 per share. Stock Options Effective January 3, 2023, the compensation committee of our board of directors granted to our employees options to purchase a total of 1,001,381 shares of our common stock at an exercise price of $48.00 per share. On the same date, certain of our non-employee directors received options to acquire a total of 70,562 shares of our common stock at an exercise price of $48.00 per share. The closing stock price on the effective date of the grants was $47.40 per share. The following tables summarize the details of options granted under our stock option plans that were still outstanding as of December 31, 2022, and the assumptions used to value those grants. All such grants were effective at the close of business on the date of grant.

Generally, each option will terminate approximat ely 10 years after the grant date. The fair value of each share-based option is estimated on the date of grant using a Black-Scholes valuation method that uses the assumptions listed above. The risk-free interest rate is based on the U.S. Treasury rate over the expected life of the option at the time of grant. The expected life is the average length of time over which we expect the employee groups will exercise their options, net of forfeitures, which is based on historical experience with similar grants. The dividend yield is estimated over the expected life of the option based on our current dividend payout, historical dividends paid, and expected future cash dividends. Expected stock volatilities are based on the movement of our stock price over the most recent historical period equivalent to the expected life of the option. A summary of activities under our stock option plans consisted of the following: Options Exercise Price (1) Remaining Life (2) Outstanding as of January 1, 2022 5,173,270 $ 30.23 6.08 Granted 713,438 $ 62.00 9.00 Exercised (346,992) $ 26.78 Cancelled/forfeited (164,980) $ 40.00 Outstanding as of December 31, 2022 5,374,736 $ 34.37 5.66 Exercisable as of December 31, 2022 2,437,636 $ 27.14 4.30 Options Exercise (1) Remaining Life (2) Outstanding as of January 1, 2021 5,914,757 $ 26.73 6.22 Granted 741,510 $ 48.00 9.00 Exercised (1,305,107) $ 24.34 Cancelled/forfeited (177,890) $ 31.22 Outstanding as of December 31, 2021 5,173,270 $ 30.23 6.08 Exercisable as of December 31, 2021 1,693,805 $ 25.11 4.68 (1) Weighted average exercise price. (2) Weighted average remaining contractual life in years. The total intrinsic value of stock options exercised during the years ended December 31, 2022, 2021, and 2020 was $10.2, $38.8, and $26.7, respectively. The intrinsic value represents the difference between the exercise price and fair value of the underlying shares at the date of exercise. At December 31, 2022, there was $14.5 of total unrecognized stock-based compensation expense related to outstanding unvested stock options granted under the employee stock option plan. This expense is expected to be recognized over a weighted average period of 4.07 years. Any future change in estimated forfeitures will impact this amount. The total grant date fair value of stock options vested under our employee stock option plan during 2022, 2021, and 2020 was $5.2, $4.8, and $6.1, respectively. Total stock-based compensation expense related to our employee stock option plan was $7.2, $5.6, and $5.7 for 2022, 2021, and 2020, respectively.

Retirement Savings Plan	Note 6. Retirement Savings PlanThe Fastenal Company and Subsidiaries 401(k) and Employee Stock Ownership Plan covers all of our employees in the United States. Our employees in Canada may participate in a Registered Retirement Savings Plan. The general purpose of both of these plans is to provide additional financial security during retirement by providing employees with an incentive to make regular savings contributions. In addition to the participation of our employees, we make annual profit sharing contributions based on an established formula. The expense recorded under this profit sharing formula was approximately $22.1, $17.4, and $16.2 for 2022, 2021, and 2020, respectively.

A reconciliation of the beginning and ending amount of total gross unrecognized tax benefits is as follows: 2022 2021 Balance at beginning of year: $ 7.4 8.8 Increase related to prior year tax positions 3.5 0.3 Increase related to current year tax positions 0.6 0.9 Decrease related to statute of limitation lapses (0.9) (2.6) Settlements (0.5) — Balance at end of year: $ 10.1 7.4 Included in the liability for gross unrecognized tax benefits is an immaterial amount for interest and penalties, both of which we classify as a component of income tax expense. The amount of unrecognized tax benefits that would favorably impact the eff ective tax rate, if recognized, is $8.6 as of December 31, 2022 and $6.5 as of December 31, 2021. We believe it is reasonably possible that a decrease of up to $5.1 in unrecognized tax benefits may be recognized by the end of 2023 as a result of the lapse of the statute of limitations. The 2022 and 2021 liability is included in deferred income taxes in the Consolidated Balance Sheets. We file income tax returns in the United States federal jurisdiction, all states, and various local and foreign jurisdictions. We are no longer subject to income tax examinations by taxing authorities for taxable years before 2019 in the case of United States federal examinations, and with limited exception, before 2017 in the case of foreign, state, and local examinations. In general, it is our practice and intention to permanently reinvest the earnings of our foreign subsidiaries and repatriate earnings only when the tax impact is zero or very minimal. Accordingly, no deferred taxes have been provided for withholding taxes or other taxes that would result upon repatriation of our approximately $447.6 of undistributed earnings from foreign subsidiaries to the U.S. as those earnings continue to be permanently reinvested.

Leases [Abstract]
Operating Leases	Note 8. Operating Leases We lease space under non-cancelable operating leases for several distribution centers, several manufacturing locations, and certain branch locations. These leases do not have significant rent escalation holidays, concessions, leasehold improvement incentives, or other build-out clauses. Further, the leases do not contain contingent rent provisions. We also lease certain semi-tractors, pick-up trucks, and computer equipment under operating leases. Certain operating leases for pick-up trucks contain residual value guarantee provisions which would generally become due at the expiration of the operating lease agreement if the fair value of the leased vehicles is less than the guaranteed residual value. The aggregate residual value guarantee related to these leases was ap proximately $86.0. We be lieve the likelihood of funding the guarantee obligation under any provision of the operating lease agreements is remote. The cost components of our operating leases were as follows for the periods ended December 31: 2022 2021 2020 Leased Leased Total Leased Leased Total Leased Leased Total Operating lease cost $ 96.8 14.7 111.5 99.7 13.7 113.4 102.5 15.1 117.6 Variable lease cost 9.7 1.5 11.2 10.4 1.3 11.7 7.2 1.5 8.7 Short-term lease cost — 26.6 26.6 — 19.2 19.2 — 23.6 23.6 Total $ 106.5 42.8 149.3 110.1 34.2 144.3 109.7 40.2 149.9 Variable lease costs are excluded from ROU assets and lease liabilities and consist primarily of taxes, insurance, and common area or other maintenance costs for our leased facilities and equipment which are paid based on actual costs incurred by the lessor as well as variable mileage costs related to our leased vehicles.

The Credit Agreement was amended and restated to, among other things: (1) increase the aggregate revolving credit commitment under the Credit Agreement, (2) extend the revolving credit maturity date to September 28, 2027, (3) provide a benchmark replacement for LIBOR with SOFR, and (4) make certain covenant changes. After giving effect to the amendment and restatement described above, we have an $835.0 committed unsecured revolving credit facility (Credit Facility) with an uncommitted accordion option to increase the aggregate revolving commitment by an additional $365.0 for a total amount of $1,200.0. The Credit Facility includes a committed letter of credit subfacility of $55.0. Any borrowings outstanding under the Credit Facility for which we have the ability and intent to pay using cash within the next 12 months will be classified as a current liability. The Credit Facility contains certain financial and other covenants, and our right to borrow under the Credit Facility is conditioned upon, among other things, our compliance with these covenants. We are currently in compliance with these covenants. Borrowings under the Credit Facility generally bear interest at a rate per annum equal to Daily Simple SOFR plus a 0.10% spread adjustment plus 0.95%. We pay a commitment fee for the unused portion of the Credit Facility. This fee is either 0.10% or 0.125% per annum based on our usage of the Credit Facility. Senior Unsecured Promissory Notes Payable On September 28, 2022, we amended our Master Note Agreement dated July 20, 2016. The Master Note Agreement was amended to, among other things: (1) increase the aggregate principal amount of notes that may be issued under the agreement from time to time, (2) extend the issuance period to September 28, 2027, (3) replace the benchmark rate for any floating rate notes that may be issued in the future under the agreement from LIBOR to SOFR, and (4) make certain changes to covenants. We have issued senior unsecured promissory notes under our master note agreement (the Master Note Agreement) in the aggregate principal amount of $330.0 as of December 31, 2022. Our aggregate borrowing capacity under the Master Note Agreement is $900.0; however, none of the institutional investors party to that agreement are committed to purchase notes thereunder. There is no amortization of these notes prior to their maturity date and interest is payable quarterly. The notes currently issued under our Master Note Agreement, including the maturity date and fixed interest rate per annum of each series of note, are contained in the table above. The Master Note Agreement contains certain financial and other covenants and we are in compliance with these covenants. Principal payments required on our outstanding indebtedness, based on the maturity dates defined within our long-term debt arrangements, for the succeeding five years, are displayed in the table below, as of December 31, 2022: Principal Payments 2023 $ 70.0 2024 60.0 2025 75.0 2026 25.0 2027 50.0 2028 and thereafter 50.0 Total $ 330.0

Commitments and Contingencies Disclosure [Abstract]
Legal Contingencies	Note 10. Legal Contingencies We are involved in certain legal actions, including those that are ordinary routine litigation incidental to our business. The outcomes of these legal actions are not within our complete control and may not be known for prolonged periods of time. In some actions, the claimants seek damages, as well as other relief, that could require significant expenditures or result in lost revenues. We record a liability for these legal actions when a loss is known or considered probable and the amount can be reasonably estimated. If the reasonable estimate of a known or probable loss is a range, and no amount within the range is a better estimate than any other, the minimum amount of the range is accrued. If a loss is reasonably possible but not known or probable, and can be reasonably estimated, the estimated loss or range of loss is disclosed. In most cases, significant judgment is required to estimate the amount and timing of a loss to be recorded. As of December 31, 2022, there were no litigation matters that we consider to be probable or reasonably possible to have a material adverse outcome.

Business Overview and Summary_2

Business Overview and Summary of Significant Accounting Policies (Policy)	12 Months Ended
	Dec. 31, 2022
Accounting Policies [Abstract]
Principles of Consolidation	The consolidated financial statements include the accounts of Fastenal Company and its subsidiaries (collectively, referred to as Fastenal or by terms such as we, our, or us). All material intercompany balances and transactions have been eliminated in consolidation.
Revenue Recognition	Net sales include products and shipping and handling charges, net of estimates for product returns and any related sales incentives. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring products. All revenue is recognized when we satisfy our performance obligations under the contract. We recognize revenue by transferring control of the promised products to the customer, with the majority of revenue recognized at the point in time the customer obtains control of the products. We recognize revenue for shipping and handling charges at the time the products are delivered to or picked up by the customer. We estimate product returns based on historical return rates. Using probability assessments, which are based on known inputs at year-end, we estimate sales incentives expected to be paid over the term of the contract. The majority of our contracts have a single performance obligation and are short term in nature. Sales taxes and value added taxes in foreign jurisdictions that are collected from customers and remitted to governmental authorities are accounted for on a net basis and therefore are excluded from net sales.
Accounts Receivable	Credit is extended based upon an evaluation of the customer's financial condition. Accounts receivable are stated at their estimated net realizable value. The allowance for credit losses is based on an income statement approach which adjusts the ending balance sheet to take into consideration expected losses over the contractual lives of the receivables, considering factors such as historical data as a basis for future expected losses.
Foreign Currency Translation and Transactions	The functional currency of our foreign operations is typically the applicable local currency. The functional currency is translated into United States dollars for balance sheet accounts, except retained earnings, using current exchange rates as of the balance sheet date, for retained earnings at historical exchange rates, and for revenue and expense accounts using a weighted average exchange rate during the applicable period. The translation adjustments are deferred as a separate component of stockholders' equity captioned accumulated other comprehensive income (loss). Gains or losses resulting from transactions denominated in foreign currencies are included in cost of sales or operating and administrative expenses.
Cash and Cash Equivalents	We consider all highly liquid investments purchased with original maturities of three months or less to be cash equivalents.
Inventories	Inventories, consisting of finished goods merchandise held for resale, are stated at the lower of cost (first in, first out method) or net realizable value. We record valuation adjustments for excess, slow-moving, and obsolete inventory that are equal to the difference between the cost and estimated net realizable value for that inventory. These estimates are based on a review and comparison of the current inventory levels to projected and historical sales of inventory.
Property and Equipment	Property and equipment are stated at cost. Depreciation on property and equipment is provided for using the straight-line method over the anticipated economic useful lives of the related property.
Leases	We determine if an arrangement contains a lease at inception. Operating leases are included in our operating lease right-of-use (ROU) assets, the current portion of operating lease liabilities, and the operating lease liabilities in our Consolidated Balance Sheets. The ROU assets represent our right to control the use of an underlying asset for the lease term, and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. The operating lease ROU assets also include any prepaid lease payments made and exclude lease incentives. Lease expense is recognized on a straight-line basis over the lease term. Many of our leases include both lease (e.g., fixed payments including rent, taxes, and insurance costs) and non-lease components (e.g., common-area or other maintenance costs) which are accounted for as a single lease component as we have elected the practical expedient to group lease and non-lease components for all leases. Our pick-up truck leases typically have a non-cancelable lease term of less than one year and therefore, we have elected the practical expedient to exclude these short-term leases from our ROU assets and lease liabilities. Most leases include one or more options to renew. The exercise of lease renewal options is typically at our sole discretion; therefore, the majority of renewals to extend the lease terms are not included in our ROU assets and lease liabilities as they are not reasonably certain of exercise. We regularly evaluate the renewal options and when they are reasonably certain of exercise, we include the renewal period in our lease term.
Long-Lived Assets	Long-lived assets consist of net property and equipment, operating lease right-of-use assets, prepaid deposits, goodwill, and definite-lived intangible assets, and are reviewed for impairment whenever an event or change in circumstance indicates that the carrying amount of the asset may not be recoverable. If circumstances require a long-lived asset or asset group be tested for possible impairment, we first compare undiscounted cash
Long-Lived Assets (Goodwill and Other)	Goodwill represents the excess of the purchase price over the fair value of net assets acquired. Goodwill is reviewed for impairment annually. The identifiable intangible assets are amortized on a straight-line basis over their estimated life.
Accounting Estimates	The preparation of the consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and the disclosure of contingent liabilities. Actual results could differ from those estimates.
Insurance Reserves	We are self-insured for certain losses relating to workers' compensation, automobile, health, and general liability costs. Specific stop-loss coverage is provided for catastrophic claims in order to limit exposure to significant claims. Self-insurance liabilities are based on our estimate of reported claims and claims incurred but not yet reported.
Product Warranties	We offer a basic limited warranty for certain of our products. The specific terms and conditions of those warranties vary depending upon the product sold. We typically recoup these costs through product warranties we hold with the original equipment manufacturers. Our warranty expense has historically been minimal.
Stock-Based Compensation	We estimate the fair value of stock options as of the date of the grant using a Black-Scholes valuation model. Stock-based compensation expense equal to the grant date fair value is recognized on a straight-line basis over the vesting period. Our stock-based compensation expense is recorded in operating and administrative expenses.
Income Taxes	We account for income taxes under the asset and liability method. Under this 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 that includes the enactment date. We recognize the effect of income tax positions only if those positions are more likely than not to be sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. We record interest and penalties related to unrecognized tax benefits in income tax expense.
Earnings Per Share	Basic net earnings per share is calculated using net earnings available to common stockholders divided by the weighted average number of shares of common stock outstanding during the year. Diluted net earnings per share is similar to basic net earnings per share except that the weighted average number of shares of common stock outstanding includes the incremental shares assumed to be issued upon the exercise of stock options considered to be 'in-the-money' (i.e., when the market price of our stock is greater than the exercise price of our outstanding stock options).
Segment Reporting	We have determined that for our North American regions we meet the aggregation criteria outlined in the accounting standards as these regions have similar: (1) economic characteristics, (2) products and services, (3) customers, (4) distribution channels, and (5) regulatory environments. Considering our operations outside of North America represent less than 10% of our net sales, net earnings, or assets, we report as a single business segment.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In March 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting , which provides temporary optional expedients and exceptions to U.S. GAAP on contract modifications, hedging relationships, and other transactions affected by reference rate reform to ease entities' financial reporting burdens as the market transitions from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. The guidance was effective upon issuance and may be applied prospectively to contract modifications made, hedging relationships entered into, and other transactions affected by reference rate reform, evaluated on or before December 31, 2022, beginning during the reporting period in which the guidance has been elected. In December 2022, the FASB issued ASU 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848 , which extended the date to December 31, 2024. We do not have any receivables, hedging relationships, lease agreements, or debt agreements that reference LIBOR or another reference rate expected to be discontinued. On September 28, 2022, we amended and restated our unsecured revolving credit agreement. At the same time, we also amended our master note agreement. As a result of those amendments, our floating rate debt no longer references a LIBOR based benchmark rate. Therefore, we will not be electing the optional practical expedients associated with this ASU.
