Business and Summary of Significant Accounting Policies (Policies) | 12 Months Ended
--- | ---
Dec. 31, 2022
Accounting Policies [Abstract] |
Business and Basis of Presentation | Business & Basis of Presentation Sleep Number Corporation and its 100%-owned subsidiaries (Sleep Number or the Company) have a vertically integrated business model and are the exclusive designer, manufacturer, marketer, retailer and servicer of Sleep Number beds which allows it to offer consumers high-quality, individualized sleep solutions and services. Sleep Number also offers FlextFit adjustable bases, and Sleep Number pillows, sheets and other bedding products. Sleep Number generates revenue by marketing its innovations directly to new and existing customers, and selling products through its Stores, Online, Phone, Chat (Total Retail) and Other. The consolidated financial statements include the accounts of Sleep Number Corporation and its subsidiaries. All significant intra-entity balances and transactions have been eliminated in consolidation.
Fiscal Year | Fiscal Year The Company’s fiscal year ends on the Saturday closest to December 31. Fiscal years and their respective fiscal year ends were as follows: fiscal 2022 ended December 31, 2022; fiscal 2021 ended January 1, 2022; and fiscal 2020 ended January 2, 2021. Fiscal 2020 had 53 weeks, 2022 and 2021 each had 52 weeks.
Use of Estimates in the Preparation of Financial Statements | Use of Estimates in the Preparation of Financial Statements The preparation of condensed consolidated financial statements in conformity with U.S. Generally Accepted Accounting Principles (GAAP) requires the Company to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, and the reported amounts of sales, expenses and income taxes during the reporting period. Predicting future events is inherently an imprecise activity and, as such, requires the use of judgment. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in these estimates will be reflected in the consolidated financial statements in future periods and could be material. Our critical accounting policies consist of stock-based compensation, warranty liabilities and revenue recognition.
Cash and Cash Equivalents | Cash and Cash EquivalentsCash and cash equivalents include highly-liquid investments with original maturities of three months or less. The carrying value of these investments approximates fair value due to their short-term maturity. The Company’s banking arrangements allow it to fund outstanding checks when presented to the financial institution for payment, resulting in book overdrafts. Book overdrafts are included in accounts payable in the consolidated balance sheets and in net increase (decrease) in short-term borrowings in the financing activities section of the Company’s consolidated statements of cash flows.
Accounts Receivable | Accounts Receivable Accounts receivable are recorded net of an allowance for expected credit losses and consist primarily of receivables from third-party financiers for customer credit purchases. The allowance is recognized in an amount equal to anticipated future write-offs. The Company estimates future write-offs based on delinquencies, aging trends, industry risk trends, its historical experience and current trends. Account balances are charged off against the allowance when the Company believes it is probable the receivable will not be recovered.
Inventories | Inventories Inventories include materials, labor and overhead and are stated at the lower of cost or net realizable value. Cost is determined by the first-in, first-out method. We review inventory quantities on hand and record reserves for obsolescence based on historical selling prices, current market conditions and forecasted product demand, to reduce inventory to net realizable value.
Property and Equipment | Property and Equipment Property and equipment, carried at cost, is depreciated using the straight-line method over the estimated useful lives of the assets. The cost and related accumulated depreciation of assets sold or retired is removed from the accounts with any resulting gain or loss included in net income in the consolidated statements of operations. Maintenance and repairs are charged to expense as incurred. Major renewals and betterments that extend useful life are capitalized. Leasehold improvements are depreciated over the shorter of the estimated useful lives of the assets or the contractual term of the lease, with consideration of lease renewal options if renewal appears probable. Estimated useful lives of the Company’s property and equipment by major asset category are as follows:
Leasehold improvements | 5 to 15 years
Furniture and equipment | 3 to 15 years
Production machinery | 3 to 7 years
Computer equipment and software | 3 to 12 years
Goodwill and Intangible Assets, Net | Goodwill and Intangible Assets, Net Goodwill is the difference between the purchase price of a company and the fair market value of the acquired company’s net identifiable assets. The Company’s intangible assets include developed technologies and trade names/trademarks. Definite-lived intangible assets are being amortized using the straight-line method over their estimated lives, ranging from 8-10 years.
Asset Impairment Charges | Asset Impairment Charges Long-lived Assets and Definite-lived Intangible Assets - the Company reviews its long-lived assets and definite-lived intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. When evaluating long-lived assets for potential impairment, the Company first compares the carrying value of the asset to the estimated future cash flows (undiscounted and without interest charges - plus proceeds expected from disposition, if any). If the estimated undiscounted cash flows are less than the carrying value of the asset, the Company calculates an impairment loss. The impairment loss calculation compares the carrying value of the asset to the asset’s estimated fair value. When the Company recognizes an impairment loss, the carrying amount of the asset is reduced to estimated fair value based on discounted cash flows, quoted market prices or other valuation techniques. Assets to be disposed of are reported at the lower of the carrying amount of the asset or fair value less costs to sell. We review retail store assets for potential impairment based on historical cash flows, lease termination provisions and expected future retail store operating results. If the Company recognizes an impairment loss for a depreciable long-lived asset, the adjusted carrying amount of the asset becomes its new cost basis and will be depreciated (amortized) over the remaining useful life of that asset. Goodwill and Indefinite-lived Intangible Assets - goodwill and indefinite-lived intangible assets are not amortized but are tested for impairment annually or when there are indicators of impairment using a fair value approach. The goodwill impairment test involves a comparison of the fair value of a reporting unit with its carrying value. Fair value is determined using a market-based approach utilizing widely accepted valuation techniques, including quoted market prices and the Company’s market capitalization. The Company has only one reporting unit, which has a negative carrying value. The reporting unit had a goodwill balance of $64 million at December 31, 2022 and January 1, 2022. Indefinite-lived intangible assets are assessed for impairment by comparing the carrying value of an asset with its fair value. If the carrying value exceeds fair value, an impairment loss is recognized in an amount equal to the excess.
Other Investments | Other InvestmentsWe have an investment in non-marketable equity securities of $1.2 million at December 31, 2022. This investment was made in a strategic product-development partner and is included in other non-current assets in our consolidated balance sheet. Non-marketable equity securities are equity securities without readily determinable fair value that are measured and recorded using a measurement alternative that measures the securities at cost minus impairment, if any, plus or minus changes resulting from qualifying observable price changes.
Warranty Liabilities | Warranty Liabilities The Company provides a limited warranty on most of the products it sells. The estimated warranty costs, which are expensed at the time of sale and included in cost of sales, are based on historical trends and warranty claim rates incurred by the Company and are adjusted for any current trends as appropriate. The majority of the Company’s warranty claims are incurred within the first year. The Company’s warranty liability contains uncertainties because its warranty obligations cover an extended period of time and require management to make estimates for claim rates and the projected cost of materials and freight associated with sending replacement parts to customers. The Company regularly assesses and adjusts the estimate of accrued warranty claims by updating claims rates for actual trends and projected claim costs. The Company classifies as non-current those estimated warranty costs expected to be paid out in greater than one year.
Fair Value Measurements | Fair Value Measurements Fair value measurements are reported in one of three levels based on the lowest level of significant input used: •Level 1 – observable inputs such as quoted prices in active markets; •Level 2 – inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and •Level 3 – unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. The Company generally estimates fair value of long-lived assets, including its retail stores, using the income approach, which the Company based on estimated future cash flows (discounted and with interest charges). The inputs used to determine fair value relate primarily to future assumptions regarding sales volumes, gross profit rates, retail store operating expenses and applicable probability weightings regarding future alternative uses. These inputs are categorized as Level 3 inputs under the fair value measurements guidance. The inputs used represent management’s assumptions about what information market participants would use in pricing the assets and are based upon the best information available at the balance sheet date.
Shareholders’ Deficit | Shareholders’ Deficit Dividends The Company is not restricted from paying cash dividends under the Credit Agreement so long as it is not in default under the Credit Agreement, the Company’s leverage ratio (as defined in the Credit Agreement) after giving effect to such restricted payments (as defined in the Credit Agreement) would not exceed 3.75:1.00 and no default or event of default (as defined in the Credit Agreement) would result therefrom. At December 31, 2022, the Company exceeded the 3.75:1.00 leverage ratio. However, Sleep Number has not historically paid, and has no current plans to pay, cash dividends on the Company’s common stock. Share Repurchases At December 31, 2022, there was $348 million remaining authorization under the $600 million board-approved share repurchase program. There is no expiration date governing the period over which the Company can repurchase shares. Any repurchased shares are constructively retired and returned to an unissued status. The cost of stock repurchases is first charged to additional paid-in-capital. Once additional paid-in capital is reduced to zero, any additional amounts are charged to accumulated deficit.
Revenue Recognition | Revenue Recognition The Company recognizes revenue when control of the promised goods or services is transferred to its customers, in an amount that reflects the consideration it expects to be entitled to in exchange for those goods or services. Revenue recognized excludes sales taxes. Amounts billed to customers for delivery and setup are included in net sales. For most products, the Company receives payment before or promptly after, the products or services are delivered to the customer. The Company accepts sales returns of most products during a 100-night trial period. Accrued sales returns represent a refund liability for the amount of consideration that the Company does not expect to be entitled to because it will be refunded to customers. The refund liability estimate is based on historical return rates and is adjusted for any current trends as appropriate. Each reporting period the Company remeasures the liability to reflect changes in the estimate, with a corresponding adjustment to net sales. Sleep Number beds sold with SleepIQ technology contain multiple performance obligations including the bed, and SleepIQ hardware and software. The Company analyzes its multiple performance obligation(s) to determine whether they are distinct and can be separated or whether they must be accounted for as a single performance obligation. We determined that beds sold with the SleepIQ technology have two performance obligations consisting of: (i) the bed; and (ii) SleepIQ hardware and software. SleepIQ hardware and software are not separable as the hardware and related software are not sold separately and the software is integral to the hardware’s functionality. The Company determined the transaction price for multiple performance obligations based on their relative standalone selling prices. The performance obligation related to the bed is satisfied at a point in time. The performance obligation related to SleepIQ technology is satisfied over time based on the ongoing access and usage by the customer of software essential to the functionality of SleepIQ technology. The deferred revenue and costs related to SleepIQ technology are recognized on a straight-line basis over the estimated period of benefit to the customer of 4.5 to 5.0 years because its inputs are generally expended evenly throughout the performance period.
Cost of Sales, Sales and Marketing, General and Administrative (G&A) and Research & Development (R&D) Expenses | Cost of Sales, Sales and Marketing, General and Administrative (G&A) and Research & Development (R&D) Expenses The following tables summarize the primary costs classified in each major expense category (the classification of which may vary within the Company’s industry):

Leases | Leases The Company determines if an arrangement is a lease at inception. Right-of-use (ROU) assets and operating lease liabilities are recognized at the lease commencement date based on the estimated present value of future lease payments over the lease term. The Company elected the option to not separate lease and non-lease components for all of its leases. Most of the Company’s leases do not provide an implicit interest rate nor is the rate available to it from its lessors. As an alternative, the Company uses its estimated incremental borrowing rate, which is derived from information available at the lease commencement date, including publicly available data, in determining the present value of lease payments. Leases with an initial term of 12 months or less are not recorded on the balance sheet as an ROU asset or operating lease liability. The Company recognizes operating lease costs for these short-term leases, primarily small equipment leases, on a straight-line basis over the lease term. At December 31, 2022, the Company’s finance lease ROU assets and associated lease liabilities were not significant. See Note 7, Leases, for further information regarding the Company’s operating leases.
Pre-Opening Costs | Pre-opening Costs Costs associated with the start-up and promotion of new retail store openings are expensed as incurred.
Advertising Costs | Advertising CostsThe Company incurs advertising costs associated with print, digital and broadcast advertisements. Advertising costs are charged to expense when the ad first runs.
Insurance | InsuranceThe Company is self-insured for certain losses related to health and workers’ compensation claims, although the Company obtains third-party insurance coverage to limit exposure to these claims. The Company estimates its self-insured liabilities using a number of factors including historical claims experience and analysis of incurred but not reported claims. The Company’s
Software Capitalization | Software Capitalization For software developed or obtained for internal use, the Company capitalizes direct external costs associated with developing or obtaining internal-use software. In addition, the Company capitalizes certain payroll and payroll-related costs for employees who are directly involved with the development of such applications. Capitalized costs related to internal-use software under development are treated as construction-in-progress until the program, feature or functionality is ready for its intended use, at which time depreciation commences. The Company expenses any data conversion or training costs as incurred. Capitalized software costs are included in property and equipment, net in the consolidated balance sheet. The Company capitalizes costs incurred with the implementation of a cloud computing arrangement that is a service contract, consistent with its policy for software developed or obtained for internal use. The capitalized implementation costs of cloud computing arrangements are expensed over the term of the cloud computing arrangement in the same line item in the statement of operations as the associated hosting fees. Capitalized costs incurred with the implementation of a cloud computing arrangement are included in prepaid expenses and other non-current assets in the Company’s consolidated balance sheet, and in operating cash flows in its consolidated statement of cash flows.
Stock-Based Compensation | Stock-based Compensation The Company compensates officers, directors and key employees with stock-based compensation under stock plans approved by its shareholders and administered under the supervision of the Company’s Board of Directors (Board). At December 31, 2022, a total of 2.1 million shares were available for future grant. These plans include non-qualified stock options and stock awards. The Company records stock-based compensation expense based on the award’s fair value at the grant date and the awards that are expected to vest. The Company recognizes stock-based compensation expense over the period during which an employee is required to provide services in exchange for the award. The Company reduces compensation expense by estimated forfeitures. Forfeitures are estimated using historical experience and projected employee turnover. The Company includes, as part of cash flows from operating activities, the benefit of tax deductions in excess of recognized stock-based compensation expense. In addition, excess tax benefits or deficiencies are recorded as discrete adjustments to income tax expense. Stock Options - stock option awards are granted at exercise prices equal to the closing price of the Company’s stock on the grant date. Generally, options vest proportionally over three years and expire after 10 years. Compensation expense is recognized ratably over the vesting period. The Company determines the fair value of stock options granted and the resulting compensation expense at the date-of-grant using the Black-Scholes-Merton option-pricing model. Descriptions of significant assumptions used to estimate the expected volatility, risk-free interest rate and expected term are as follows: Expected Volatility – expected volatility was determined based on implied volatility of the Company’s traded options and historical volatility of the Company’s stock price. Risk-Free Interest Rate – the risk-free interest rate was based on the implied yield available on U.S. Treasury zero-coupon issues at the date of grant with a term equal to the expected term. Expected Term – expected term represents the period that the Company’s stock-based awards are expected to be outstanding and was determined based on historical experience and anticipated future exercise patterns, giving consideration to the contractual terms of unexercised stock-based awards. Stock Awards - the Company issues stock awards to certain employees in conjunction with its stock-based compensation plan. The stock awards generally vest over three years based on continued employment (time-based). Compensation expense related to stock awards, except for stock awards with a market condition, is determined on the grant date based on the publicly quoted closing price of the Company’s common stock and is charged to earnings on a straight-line basis over the vesting period. Stock awards with a market condition are valued using a Monte Carlo simulation model. The significant assumptions used to estimate the expected volatility and risk-free interest rate are similar to those described above in Stock Options. In April 2020, the Company took action to maintain liquidity and cut costs in response to the COVID-19 pandemic, including offering a salary for stock program. Under that program, certain employees elected to forego a percentage of their cash salary for the remainder of the year in exchange for time-based stock awards that represented the value of the cash salary foregone. Subject to continuing employment, these awards vested in December 2020. Certain time-based stock awards have a performance condition (performance-based). The final number of shares earned for performance-based stock awards and the related compensation expense is adjusted up or down to the extent the performance target is met. The actual number of shares that will ultimately be awarded range from 0% - 200% of the targeted amount for the 2022, 2021 and 2020 awards. We evaluate the likelihood of meeting the performance targets at each reporting period and adjust compensation expense, on a cumulative basis, based on the expected achievement of each of the performance targets. For performance-based stock awards granted in 2022, 2021 and 2020, the performance targets are based on growth in net sales and in operating profit, and the performance periods are fiscal 2022 through 2024, 2021 through 2023 and fiscal 2020 through 2022, respectively.
Income Taxes | Income Taxes The Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to temporary 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. A valuation allowance is established for any portion of deferred tax assets that are not considered more likely than not to be realized. The Company evaluates all available positive and negative evidence, including its forecast of future taxable income, to assess the need for a valuation allowance on its deferred tax assets. The Company records a liability for unrecognized tax benefits from uncertain tax positions taken, or expected to be taken, in the Company’s tax returns. The Company follows a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the available evidence indicates it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount which is more than 50% likely of being realized upon ultimate settlement. The Company considers many factors when evaluating and estimating its tax positions and tax benefits, which may require periodic adjustments, and may not accurately forecast actual outcomes. The Company classifies net interest and penalties related to income taxes as a component of income tax expense in its consolidated statements of operations.
Net Income Per Share | Net Income Per Share The Company calculates basic net income per share by dividing net income by the weighted-average number of common shares outstanding during the period. It calculates diluted net income per share based on the weighted-average number of common shares outstanding adjusted by the number of potentially dilutive common shares as determined by the treasury stock method. Potentially dilutive shares consist of stock options and stock awards.
Sources of Supply | Sources of Supply The Company currently obtain materials and components used to produce its beds from outside sources. As a result, the Company is dependent upon suppliers that in some instances, are its sole source of supply, or supply the vast majority of the particular component or material. We continuously evaluate opportunities to dual-source key components and materials. The failure of one or more of the Company’s suppliers to provide it with materials or components on a timely basis could significantly impact the consolidated results of operations and net income per share. While the Company believes that these materials and components, or suitable replacements, could be obtained from other sources in the event of a disruption or loss of supply, it may not be able to find alternative sources of supply or alternative sources of supply on comparable terms and an unexpected loss of supply over a short period of time may not allow the Company to replace these sources in the ordinary course of business.
