Accounting Policies [Abstract] |
Principles of consolidation | Principles of consolidation: The consolidated financial statements include the financial statements of Casey’s General Stores, Inc. and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. Certain amounts in prior year have been reclassified to conform to current year presentation.
Use of estimates | Use of estimates: The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Cash equivalents | Cash equivalents: We consider all highly liquid investments with a maturity at purchase of three months or less to be cash equivalents. Included in cash equivalents are money market funds and credit card, debit card and electronic benefits transfer transactions that process within three days.
Inventories | Inventories: Inventories, which consist of merchandise and fuel, are stated at the lower of cost or market. For fuel, cost is determined through the use of the first-in, first-out (FIFO) method. For merchandise inventories, cost is determined through the use of the last-in, first-out (LIFO) method. The excess of replacement cost over the stated LIFO value was $87,546 and $80,814 at April 30, 2020 and 2019, respectively. There were no material LIFO liquidations during the periods presented. Below is a summary of the inventory values at April 30, 2020 and 2019:
| Years ended April 30,
| 2020 |  | 2019
Fuel | $ | 33,695 |  |  | $ | 83,204 |
Merchandise | 202,312 |  |  | 189,836 |
Total inventory | $ | 236,007 |  |  | $ | 273,040 |
The Company often receives vendor allowances on the basis of quantitative contract terms that vary by product and vendor or directly on the basis of purchases made. Vendor allowances include rebates and other funds received from vendors to promote their products. Vendor rebates, including billbacks, are treated as a reduction in cost of goods sold and are recognized primarily based on the purchase of product or shipment of product from the warehouse to the store, or sale of product to our guests. These are recognized in the period earned based on the applicable rebate agreement. Reimbursements of an operating expense (e.g., advertising) are recorded as reductions of the related expense. Renewable Identification Numbers (RINs) are recorded as a reduction in cost of goods sold in the period when the Company commits to a price and agrees to sell all of the RINs earned during a specified period. The Company includes in cost of goods sold the costs incurred to acquire fuel and merchandise, including excise taxes, less vendor allowances and rebates and RINs. The Company does not record an asset on the balance sheet related to RINs that have not been validated and contracted. Warehousing costs are recorded within operating expenses on the consolidated statements of income.
Capitalized software implementation costs and Goodwill | Capitalized software implementation costs: The Company capitalizes expenditures related to the implementation of software as incurred. These costs are expensed on a straight-line basis within operating expenses over the contractual life of the contract with the related software provider. The useful lives utilized for capitalized software implementation costs range from 3-13 years. As of April 30, 2020 and April 30, 2019, the Company had recognized $38,593 and $27,873 of capitalized software implementation costs, respectively. The outstanding balance is recognized in other assets on the consolidated balance sheets. Goodwill: Goodwill and intangible assets with indefinite lives are tested for impairment at least annually. The Company assesses impairment annually at year-end using a market based approach to establish fair value. All of the goodwill assigned to the individual stores is aggregated into a single reporting unit due to the similar economic characteristics of the stores.
Depreciation and amortization | Depreciation and amortization: Depreciation of property and equipment are computed using the straight-line method over the following estimated useful lives:
Buildings | 25-40 years
Machinery and equipment | 5-40 years
Finance lease right-of-use assets | Lesser of term of lease or life of asset
Leasehold improvements | Lesser of term of lease or life of asset
The Company monitors stores and will accelerate depreciation if the expected life of the asset is reduced due to the expected remaining operation of the store or the Company’s plans. Construction in process is reported at cost and not subject to depreciation until the related asset is placed in service.
Store closing and asset impairment | Store closings and asset impairment: The Company writes down property and equipment of stores it is closing to estimated net realizable value at the time management commits to a plan to close such stores and begins active marketing of the stores. The Company bases the estimated net realizable value of property and equipment on its experience in utilizing and/or disposing of similar assets, as well as estimates provided by its own and/or third-party real estate experts. The Company monitors closed and underperforming stores for an indication that the carrying amount of assets may not be recoverable. If the sum of the expected future undiscounted cash flows is less than the carrying amount of the assets, an impairment loss is recognized to the extent carrying value of the assets exceeds their estimated fair value. Fair value is based on management’s estimate of the price that would be received to sell an asset in an orderly transaction between market participants. The estimate is derived from offers, actual sale or disposition of assets subsequent to year-end, and other indications of fair value, which are considered Level 3 inputs (see Note 3). In determining whether an asset is impaired, assets are grouped at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows of other groups of assets, which for the Company is generally on a store-by-store basis.
Income taxes | Income taxes: The Company uses the asset and liability method of accounting for income taxes. 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. The Company calculates its current and deferred tax provision based on estimates and assumptions that could differ from actual results reflected in income tax returns filed in subsequent years. Adjustments based on filed returns are recorded when identified.
Revenue recognition | Revenue recognition: The Company recognizes retail sales of fuel, grocery and other merchandise, prepared food and fountain and other revenue at the time of the sale to the guest. Sales taxes collected from guests and remitted to the government are recorded on a net basis in the consolidated financial statements. A portion of revenue from sales that include a redeemable box top coupon or points under our Casey’s Rewards program is deferred. The deferred portion of the sale represents the value of the estimated future redemption of the box top coupon or points. The amounts related to redeemable box top coupons and points are deferred until their redemption or expiration. Revenue related to the box top coupons and points issued is expected to be recognized less than one year from the original sale to the guest. As of April 30, 2020 and April 30, 2019, the Company recognized a contract liability of $11,180 and $6,931, respectively, related to the outstanding box top coupons and Casey's Rewards points, which is included in other accrued expenses on the consolidated balance sheets. Gift card related revenue is recognized as the gift cards are used by the guest. Gift card breakage revenue is recognized based on the estimated gift card breakage rate over the pro rata usage of the card.
Net income per common share | Net income per common share: Basic earnings per share have been computed by dividing net income by the weighted average shares outstanding during each of the years. Unvested shares under equity awards are treated as common shares within the basic earnings per share calculation when a team member has met certain requirements in the award agreement. For example, if retirement provisions are satisfied which allow a team member to avoid forfeiture of the award upon a normal retirement from the Company, it is included in the basic earnings per share calculation. The calculation of diluted earnings per share treats stock options and unvested restricted stock units with time-based restrictions as potential common shares to the extent they are dilutive. The diluted earnings per share calculation does not take into effect any shares that have not met performance or market conditions as of the reporting period.
Asset retirement obligations | Asset retirement obligations: The Company recognizes the estimated future cost to remove underground storage tanks over the estimated useful life of the storage tank. The Company records a discounted liability for the fair value of an asset retirement obligation with a corresponding increase to the carrying value of a long-lived asset at the time an underground storage tank is installed. The Company amortizes the amount added to property and equipment on a straight-line basis and recognizes accretion expense in connection with the discounted liability over the remaining life of the tank. The estimates of the anticipated future costs for removal of an underground storage tank are based on our prior experience with removal. Because these estimates are subjective and are currently based on historical costs with adjustments for estimated future changes in the associated costs, we expect the dollar amount of these obligations to change as more information is obtained.
Self-insurance | Self-insurance: The Company is primarily self-insured for team member healthcare, workers’ compensation, general liability, and automobile claims. The self-insurance claim liability for workers’ compensation, general liability, and automobile claims is determined actuarially at each year end based on claims filed and an estimate of claims incurred but not yet reported. Actuarial projections of the losses are employed due to the potential of variability in the liability estimates. Some factors affecting the uncertainty of the claim liability include the loss development factors, which includes the development time frame and settlement patterns, and expected loss rates, which includes litigation and adjudication direction, and medical treatment and cost trends. The liability is not discounted.
Environmental remediation liabilities | Environmental remediation liabilities: The Company accrues for environmental remediation liabilities when it is probable a liability has been incurred and the amount of loss can be reasonably estimated.
Derivatives instruments | Derivative instruments: There were no options or futures contracts as of or during the years ended April 30, 2020, 2019, or 2018. However, we do from time to time, participate in a forward buy of certain commodities. These are not accounted for as derivatives under the normal purchase and sale exclusions within the applicable accounting guidance.
Stock-based compensation | Stock-based compensation: Stock-based compensation is recorded based upon the fair value of the award on the grant date. The cost of the award is recognized ratably in the consolidated statements of income over the vesting period of the award, adjusted for certain retirement provisions. Additionally, certain awards include performance and market conditions. The majority of performance-based awards are based on the achievement of a three year average return on invested capital (ROIC). For these awards, stock-based compensation expense is estimated based on the probable outcome of shares to be awarded adjusted as necessary at each reporting period. The market-based awards are achieved based on our relative performance to a pre-determined peer group. The fair value of these awards is determined using a Monte Carlo simulation as of the date of the grant. For market-based awards, the stock-based compensation expense will not be adjusted should the target awards vary from actual awards.
Segment reporting | Segment reporting: As of April 30, 2020, we operated 2,207 stores in 16 states. Our convenience stores offer a broad selection of merchandise, fuel and other products and services designed to appeal to the convenience needs of our guests. We manage the business on the basis of one operating segment and therefore, have only one reportable segment. Our stores sell similar products and services, use similar processes to sell those products and services, and sell their products and services to similar classes of guests. We make specific disclosures concerning the three broad merchandise categories of fuel, grocery and other merchandise, and prepared food and fountain because it makes it easier for us to discuss trends and operational initiatives within our business and industry. Although we can separate revenues and cost of goods sold within these categories (and further sub-categories), the operating expenses associated with operating a store that sells these products are not separable by these three categories.
Recent accounting pronouncements | Recent accounting pronouncements: In May 2014, the FASB issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606). We adopted the standard on May 1, 2018 using the modified retrospective approach. The Company adopted two changes that affect the timing of recognition of revenues related to gift card breakage income and the redemption of coupon box tops attached to our pizza boxes. The impact related to gift cards was $879, net of $321 of deferred taxes and was an increase to shareholders' equity with a reduction in deferred income. The impact related to box tops was $5,019, net of $1,816 of deferred taxes and was a reduction in shareholders' equity, with an increase in deferred income. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This update seeks to increase the transparency and comparability among entities by requiring public entities to recognize lease assets and lease liabilities on the balance sheet and disclose key information about leasing arrangements. To satisfy the standard’s objective, a lessee will recognize a right-of-use asset representing its right to use the underlying asset for the lease term and a lease liability for the obligation to make lease payments. Both the right-of-use asset and lease liability will initially be measured at the present value of the lease payments, with subsequent measurement dependent on the classification of the lease as either a finance or an operating lease. For leases with a term of twelve months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. If a lessee makes this election, it should recognize lease expense for such leases generally on a straight-line basis over the lease term. In July 2018, the FASB issued ASU 2018-10, Leases (Topic 842) - Codification Improvements which contains several FASB Codification improvements for ASC Topic 842, including several implementation issues and ASU 2018-11, "Leases (Topic 842) - Targeted Improvements" which provides entities with an additional transition method for implementing ASC Topic 842. Entities have the option to apply the new standard at the adoption date, recognizing a cumulative-effect adjustment to the opening balance of retained earnings along with the modified retrospective approach previously identified, both of which include a number of practical expedients that companies may elect to apply. Under the cumulative-effect adjustment comparative periods would not be restated. Under the modified retrospective approach leases are recognized and measured under the noted guidance at the beginning of the earliest period presented. The new standard is effective for public companies for annual periods beginning after December 15, 2018, and interim periods within those years, with early adoption permitted. We adopted this guidance as of May 1, 2019 using the modified retrospective approach and elected the cumulative-effect adjustment practical expedient. As a result of the transition method selected, the Company did not restate previously reported comparable periods. Please refer to note 7 for additional information regarding the Company’s adoption of ASC 842. In October 2016, the FASB issued ASU No. 2016-16, Intra-Entity Transfers of Assets Other than Inventory. We adopted this standard in the quarter ended July 31, 2018, which resulted in no material impact to the Company. In January 2017, the FASB issued ASU 2017-01, Business Combinations, Clarifying the Definition of a Business. The standard clarifies the definition of a business and adds guidance to assist entities in the determination of whether an acquisition (or disposal) represents assets or a business. The guidance requires the Company to utilize various criteria to evaluate whether or not an acquisition is a business. First, if substantially all of the fair value of the assets acquired is concentrated in a single asset or a group of similar identifiable assets, the acquired assets do not represent a business. If that is not the case, the update provides further guidance to evaluate if the acquisition represents a business focused on the nature and substance of the inputs and process acquired. The standard is generally expected to reduce the number of business combinations, which may impact the allocation of purchase consideration in future acquisitions. Where it is determined that an acquisition is not a business combination, there would be no resulting goodwill recorded. The Company prospectively adopted this guidance for all future acquisitions in the first quarter of fiscal 2019. In August 2018, the FASB issued ASU 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. This standard provides guidance on accounting for costs of implementation activities performed in a cloud computing arrangement that is a service contract. The amendments in the update align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software and hosting arrangements that include an internal-use software license. The Company early adopted this guidance retrospectively, in the first quarter of fiscal 2019. The adoption did not have a material impact on our consolidated financial statements. In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes. The standard includes changes that eliminate certain exceptions related to the approach for intraperiod tax allocation and the methodology for calculating income taxes in an interim period. It also simplifies aspects of the accounting for franchise taxes, certain transactions that result in a step-up in the tax basis of goodwill, and enacted changes in tax laws or rates. The Company is required to adopt this guidance in the first quarter of its fiscal 2022, with early adoption permitted. The Company is currently evaluating the impact the standard has on the consolidated financial statements. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The standard included optional guidance for a limited period of time to help ease the burden in accounting for the effects of reference rate reform. The new standard is effective for all entities through December 31, 2022. The Company does not expect the adoption of this standard to have a material impact on our consolidated financial statements.
Leases | The Company is a lessee in situations where we lease property and equipment, most commonly land or building, from a lessor. The Company is a lessor in situations where the Company owns land or building and leases a portion or all of the property or equipment to a tenant. In both situations, leases are reported in accordance with ASC 842 - Leases. As a lessee, the Company recognizes a right-of-use asset representing its right to use the underlying asset for the lease term and a lease liability for the obligation to make lease payments. Both the right-of-use asset and lease liability are initially measured at the present value of the lease payments, with subsequent measurement dependent on the classification of the lease as either a finance or an operating lease. For leases with a term of twelve months or less, we have elected to not recognize lease assets and lease liabilities and will recognize lease expense on a straight-line basis over the lease term. The Company records the operating lease liability in accrued expenses and other long-term liabilities and records the finance lease liability within current maturities of long-term debt and long term debt and finance lease obligations on the consolidated balance sheets. We have elected to adopt the package of practical expedients, as well as the land easement practical expedient. All lessor related activity is considered immaterial to the consolidated financial statements. The leases initially recorded under ASC 842 were recognized, at the time of adoption, at an amount equal to the present value of the lease payments using the incremental borrowing rate of debt based upon the remaining term of the lease. New leases are recognized at the present value of the lease payments using the implicit rate in the lease agreement when it is readily determinable. In the case the implicit rate is not readily determinable, the Company uses the incremental borrowing rate of debt based on the term of the lease. Several leases have variable payment components of the lease such as commission based payments or payments for property taxes and insurance. For these leases, the Company has not included those variable payments in the calculation of the lease liability as the payments are not in-substance fixed and do not depend on an index or rate. These variable payments will be expensed as incurred. The Company also has options to renew or extend the current lease arrangement on many of our leases. In these situations, if it was reasonably certain the lease would be extended, we have included those extensions within the remaining lease payments at the time of measurement.
