Notes to Condensed Consolidated Financial Statements

(unaudited)

1. Business and Summary of Significant Accounting Policies

Business & Basis of Presentation

We prepared the condensed consolidated financial statements as of and for the three and six months ended June 30, 2018 of Sleep Number Corporation and 100%-owned subsidiaries (Sleep Number or the Company), without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) and they reflect, in the opinion of management, all normal recurring adjustments necessary to present fairly our financial position as of June 30, 2018 and December 30, 2017, and the consolidated results of operations and cash flows for the periods presented. Our historical and quarterly consolidated results of operations may not be indicative of the results that may be achieved for the full year or any future period.

Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (GAAP) have been condensed or omitted pursuant to such rules and regulations. These condensed consolidated financial statements should be read in conjunction with our most recent audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the fiscal year ended December 30, 2017 and other recent filings with the SEC.

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires us 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. Our critical accounting policies consist of stock-based compensation, goodwill and indefinite-lived intangible assets, warranty liabilities and revenue recognition.

The condensed consolidated financial statements include the accounts of Sleep Number Corporation and our 100%-owned subsidiaries. All significant intra-entity balances and transactions have been eliminated in consolidation.

New Accounting Pronouncements

Recently Adopted Accounting Guidance

Adoption of ASC Topic 230, Restricted Cash

Effective December 31, 2017, we adopted ASC Topic 230, Restricted Cash, which requires amounts generally described as restricted cash and restricted cash equivalents be included with cash and cash equivalents when reconciling the total beginning and ending amounts for the periods shown on the statement of cash flows. Amounts for prior periods have been retrospectively adjusted to conform to the current period presentation.

Adoption of ASC Topic 606, Revenue from Contracts with Customers

On December 31, 2017, we adopted ASC Topic 606, Revenue from Contracts with Customers, using the modified retrospective method applied to those contracts which were not completed as of December 30, 2017. Results for reporting periods beginning after December 30, 2017 are presented under the new guidance, while prior period amounts are not restated.

The cumulative effect of the changes made to our consolidated balance sheet as of December 31, 2017 resulting from the adoption of the new revenue guidance was not material and did not impact opening retained earnings. The impact on the timing of net sales for the three and six months ended June 30, 2018, as a result of applying the new guidance, was not material.

Practical expedients and exemptions permissible under ASC Topic 606 that we elected are as follows: we do not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less; and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed.

See Note 2, Revenue Recognition, for further details regarding our revenue recognition policy.

Accounting Guidance Issued but Not Yet Adopted as of June 30, 2018

In February 2016, the FASB issued ASC Topic 842, Leases, that requires most leases to be recognized on the balance sheet and expands disclosure requirements. The provisions of this new guidance permit us to utilize a prospective approach, with elective reliefs. We are the lessee under various agreements for facilities and equipment that are currently accounted for as operating leases. This new guidance is effective for us beginning December 30, 2018 and we are in the process of implementing a new lease accounting system in connection with the adoption. While we expect a material impact to our consolidated balance sheet as a result of the adoption of this new guidance, we continue to evaluate the effect of the new standard on our consolidated financial statements and related disclosures. We also expect that adoption of the new guidance will require changes to our internal controls over financial reporting.

2. Revenue Recognition

We recognize revenue when control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration we expect 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, we require payment before the products or services are delivered to the customer.

Our beds sold with SleepIQ^® technology contain multiple performance obligations including the bed and SleepIQ’s hardware and software. We analyze our 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 the beds sold with the SleepIQ technology have two performance obligations consisting of: (i) the bed; and (ii) SleepIQ's hardware and software. SleepIQ’s 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. We determine 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 product’s estimated life of four years because our inputs are generally expended evenly throughout the performance period.

At June 30, 2018 and December 30, 2017, we had deferred contract liabilities of $71 million and $73 million, of which $31 million and $30 million are included in other current liabilities, respectively, and $40 million and $43 million are included in other non-current liabilities, respectively, in our consolidated balance sheets. We also had deferred contract assets of $45 million and $43 million, of which $19 million and $17 million are included in other current assets, respectively, and $26 million and $26 million are included in other non-current assets, respectively, in our consolidated balance sheets. During the three and six months ended June 30, 2018, we recognized revenue of $8 million and $16 million, respectively, that was included in the deferred contract liability balance at the beginning of the period.

Revenue from goods and services transferred to customers at a point in time accounted for approximately 97% and 98% of our revenues for the three and six months ended June 30, 2018, respectively.

Net sales from each of our channels was as follows (in thousands):



	Three Months Ended		Six Months Ended
	June 30, 2018		June 30, 2018
Retail	$	286,853	$	642,922

Obligation for Sales Returns

We accept sales returns during a 100-night trial period. Accrued sales returns represents a refund liability for the amount of consideration that we do 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 we remeasure the liability to reflect changes in the estimate, with a corresponding adjustment to net sales. The activity in the sales returns liability account was as follows (in thousands):



	Six Months Ended
	June 30, 2018			July 1, 2017
Balance at beginning of year	$	19,270		$	15,222
Additions that reduce net sales	36,555			32,434
Deductions from reserves	(39,298		)	(35,054		)
Balance at end of period	$	16,527		$	12,602

3. Fair Value Measurements

At June 30, 2018 and December 30, 2017, we had $5 million and $4 million, respectively, of debt and equity securities that fund our deferred compensation plan and are classified in other non-current assets. We also had corresponding deferred compensation plan liabilities of $5 million and $4 million at June 30, 2018 and December 30, 2017, respectively, which are included in other non-current liabilities. The majority of the debt and equity securities are Level 1 as they trade with sufficient frequency and volume to enable us to obtain pricing information on an ongoing basis. Unrealized gains/(losses) on the debt and equity securities offset those associated with the corresponding deferred compensation plan liabilities.

4. Inventories

Inventories consisted of the following (in thousands):



	June 30, 2018		December 30, 2017
Raw materials	$	4,285	$	6,577
Work in progress	214		170
Finished goods	85,742		77,551

Goodwill and Indefinite-Lived Intangible Assets

Goodwill was $64 million at June 30, 2018 and December 30, 2017. Indefinite-lived trade name/trademarks totaled $1.4 million at June 30, 2018 and December 30, 2017.

Definite-Lived Intangible Assets

6. Credit Agreement

Our $300 million credit facility is for general corporate purposes and is also utilized to meet our seasonal working capital requirements. The credit agreement provides the lenders with a collateral security interest in substantially all of our assets and those of our subsidiaries and requires us to comply with, among other things, a maximum leverage ratio and a minimum interest coverage ratio. Under the terms of the credit agreement we pay a variable rate of interest and a commitment fee based on our leverage ratio. The credit agreement includes an accordion feature which allows us to increase the amount of the credit facility from $300 million to $450 million, subject to lenders' approval. The credit agreement matures in February 2023. We were in compliance with all financial covenants as of June 30, 2018.

The following tables summarizes our borrowings under the credit facility ($ in thousands):



	June 30, 2018			December 30, 2017
Outstanding borrowings	$	182,500		$	24,500

There is no expiration date governing the period over which we 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) retained earnings.

11. Net Income (Loss) per Common Share

The components of basic and diluted net income (loss) per share were as follows (in thousands, except per share amounts):



	Three Months Ended					Six Months Ended
	June 30, 2018		July 1, 2017			June 30, 2018		July 1, 2017
Net income (loss)	$	3,744	$	(778	)	$	24,292	$	23,683

Reconciliation of weighted-average shares outstanding:
Basic weighted-average shares outstanding	36,138		41,716			37,191		42,233
Dilutive effect of stock-based awards	706		—			905		847
Diluted weighted-average shares outstanding	36,844		41,716			38,096		43,080

Net income (loss) per share – basic	$	0.10	$	(0.02	)	$	0.65	$	0.56
Net income (loss) per share – diluted	$	0.10	$	(0.02	)	$	0.64	$	0.55

For the three months ended June 30, 2018 and the six months ended June 30, 2018 and July 1, 2017, anti-dilutive stock-based awards excluded from the diluted net income per share calculations were immaterial. For the three months ended July 1, 2017, potentially dilutive stock-based awards have been excluded from the calculation of diluted weighted-average shares outstanding, as their inclusion would have had an anti-dilutive effect on our net loss per diluted share.

12. Income Taxes

As a result of the enactment of the Tax Cuts and Jobs Act (TCJA), we recorded a provisional tax benefit of $1.7 million in the fourth quarter of 2017 based on our initial analysis of the TCJA using the best information and estimates available. During the second quarter 2018, we updated our provisional tax benefit based on new information, including a tax planning analysis, and recorded an additional $2.9 million provisional tax benefit.

Due to the significant complexity of the TCJA, anticipated further guidance from the U.S. Treasury, the potential for additional guidance from the SEC/ FASB, or other new information becoming available, our provisional tax benefit may be further adjusted during 2018. Our provisional estimate is expected to be finalized no later than the fourth quarter of 2018. Further guidance and additional information regarding the TCJA may also impact our 2018 effective income tax rate, exclusive of any adjustment to the provisional tax benefit.

Legal Proceedings

We are involved from time to time in various legal proceedings arising in the ordinary course of our business, including primarily commercial, product liability, employment and intellectual property claims. In accordance with generally accepted accounting principles in the United States, we record a liability in our consolidated financial statements with respect to any of these matters when it is both probable that a liability has been incurred and the amount of the liability can be reasonably estimated. With respect to currently pending legal proceedings, we have not established an estimated range of reasonably possible additional losses either because we believe that we have valid defenses to claims asserted against us or the proceeding has not advanced to a stage of discovery that would enable us to establish an estimate. We currently do not expect the outcome of these matters to have a material effect on our consolidated results of operations, financial position or cash flows. Litigation, however, is inherently unpredictable, and it is possible that the ultimate outcome of one or more claims asserted against us could adversely impact our consolidated results of operations, financial position or cash flows. We expense legal costs as incurred.

On January 12, 2015, Plaintiffs David and Katina Spade commenced a purported class action lawsuit in New Jersey state court against Sleep Number alleging that Sleep Number violated New Jersey consumer statutes by failing to provide to purchasing consumers certain disclosures required by the New Jersey Furniture Regulations. It is undisputed that plaintiffs suffered no actual damages or in any way relied upon or were impacted by the alleged omissions. Nonetheless, on behalf of a purported class of New Jersey purchasers of Sleep Number beds and bases, plaintiffs seek to recover a $100 statutory fine for each alleged omission, along with attorneys’ fees and costs. Sleep Number removed the case to the United States District Court for the District of New Jersey, which subsequently granted Sleep Number’s motion to dismiss. Plaintiffs appealed to the United States Court of Appeals for the Third Circuit, which certified two questions of law to the New Jersey Supreme Court relating to whether plaintiffs who have suffered no actual injury may bring claims. The New Jersey Supreme Court accepted the certified questions and on April 16, 2018, ruled in our favor on one of the two questions, holding that a consumer only has standing to bring a claim under the relevant statute if the consumer has been harmed by the defendant's conduct. The Third Circuit has remanded the case to the federal district court for further analysis consistent with the New Jersey Supreme Court’s opinion. As a result, we expect that the federal district court will dismiss any claims that Plaintiffs attempt to pursue consistent with the guidance set forth by the New Jersey Supreme Court.

Company Overview

Sleep Number Corporation, based in Minneapolis, Minnesota, was founded in 1987. We are listed on The NASDAQ Stock Market LLC (NASDAQ Global Select Market) under the symbol “SNBR.”

Our mission is to improve lives by individualizing sleep experiences. Our vision is to become one of the world's most beloved brands

by delivering an unparalleled sleep experience. We plan to achieve this by executing our Consumer Innovation Strategy, which includes three significant competitive advantages: proprietary sleep innovations, lifelong customer relationships and exclusive retail distribution.

We have a direct-to-consumer, vertically integrated business model and are the exclusive designer, manufacturer, marketer, retailer and servicer of Sleep Number® beds. We offer consumers high-quality, individualized sleep solutions and services, including a complete line of Sleep Number beds, bases and bedding accessories. We are the pioneer in biometric sleep tracking and adjustability. SleepIQ® technology is a proprietary sensor technology that tracks each individual’s sleep and uses algorithms to automatically adjust the comfort level of each sleeper by working directly with our bed’s DualAir™ system. Through daily digital interactions that build lifelong relationships, SleepIQ technology also communicates how you slept and provides insights on what adjustments you can make to optimize your sleep and improve your daily life. Sleep Number also offers FlexFit™ adjustable bases, and Sleep Number pillows, sheets and other bedding products. As a national specialty mattress retailer, we provide customers a cohesive experience across our Sleep Number stores, online at SleepNumber.com or via phone at (800)753-3768.

We are committed to delivering superior shareholder value through three primary drivers of earnings per share growth: increasing

consumer demand, leveraging our business model and deploying capital efficiently. As the sleep innovation leader, we drive

growth through effective brand marketing, our proprietary innovations and a differentiated retail experience.

We generate revenue by marketing our innovations to new and existing customers, and selling products directly to consumers through Stores, Online, Chat and Phone, which we reference as our Company-Controlled channel. We also have a small Wholesale business in the United States.

We are the only vertically integrated bed manufacturer/retailer in the U.S. We have two manufacturing plants that distribute Sleep

Number products. We offer mattress home delivery and installation, and maintain an in-house customer service department. This

integration enables operational synergies and efficiencies, and a strong working capital position. Vertical integration allows us to build

a long-term loyal customer relationship as we service the consumer through the full purchase and ownership cycle. This relationship

with our customer creates a productive cycle of referral and repeat business.

Results of Operations

Quarterly and Year-to-Date Results

Quarterly and year-to-date operating results may fluctuate significantly as a result of a variety of factors, including increases or decreases in sales, the timing, amount and effectiveness of advertising expenditures, changes in sales return rates or warranty experience, timing of investments in growth initiatives and infrastructure, timing of store openings/closings and related expenses, changes in net sales resulting from changes in our store base, the timing of new product introductions and related expenses, the timing of promotional offerings, competitive factors, changes in commodity costs, any disruptions in supplies or third-party service providers, seasonality of retail and bedding industry sales, consumer confidence and general economic conditions. Therefore, our historical results of operations may not be indicative of the results that may be achieved for any future period.

Highlights

Financial highlights for the period ended June 30, 2018 were as follows:

•

Net sales for the three months ended June 30, 2018 increased 11% to $316 million, compared with $285 million for the same period one year ago. Net sales for the comparable period one year ago were affected by an approximately $25 million shift in sales from our second quarter to our third quarter as a result of a delay in deliveries and shipments related to an inventory shortage at a new supplier.


•	The 11% sales increase resulted from a 9% comparable sales increase in our Company-Controlled channel and 3 percentage points (ppt.) of growth from sales generated by 16 net new stores opened in the past 12 months.


•	The transition to our full line of Sleep Number 360^® smart beds continued during the quarter and is now complete. In May 2017, we began selling our i7 and i10 smart beds. We launched a third smart bed model (the p6) in December 2017. In April 2018, we

Index

introduced the Sleep Number 360 p5 and i8 smart beds, our two most popular models. Our c4 and c2 models completed the transition in June and July 2018, respectively. The Sleep Number 360 smart bed won 13 awards at CES 2017, including being named the Best of Innovation Honoree in the Home Appliance category. It also received the 2018 Edison Silver Award for breakthrough product design and innovation in the Wellness Technology category.


•	Sales per store (Company-Controlled channel sales for stores open at least one year) on a trailing twelve-month basis for the period ended June 30, 2018 totaled $2.6 million, 4% higher than the same period one-year ago.

•

Operating income for the three months ended June 30, 2018 was $2 million, a $5 million increase from an operating loss of $3 million for the prior-year period. Our operating income rate increased to 0.7% of net sales, compared with an operating loss rate of 1.1% of net sales for the same period last year. The current-period's operating income rate benefited from operating expense controls and sales leverage which mitigated the lower gross profit rate. Prior year's operating loss was affected by the sales shift discussed above.


•	Net income for the three months ended June 30, 2018 was $4 million, or $0.10 per diluted share, compared with a net loss of $1 million, or $(0.02) per diluted share, for the same period one year ago. The current quarter includes a one-time tax planning benefit of $2.9 million, or $0.08 per diluted share, associated with the new Tax Cuts and Jobs Act.

•

Cash provided by operating activities totaled $29 million for the six months ended June 30, 2018, compared with $89 million for the same period one year ago. The largest drivers in the year-over-year change in operating cash flows resulted from the timing of performance-based incentive compensation payments and expenses, fluctuations in customer prepayments resulting from higher than normal prepayments at July 1, 2017 (delayed deliveries and shipments due to an inventory shortage from one of our new suppliers) and year-over-year changes in inventory levels. Investing activities for the current-year period included $21 million of property and equipment purchases, compared with $27 million for the same period last year.


•	At June 30, 2018, cash and cash equivalents totaled $2 million and we ended the quarter with $183 million of borrowings under our $300 million revolving credit facility.


•	In the second quarter of 2018, we repurchased 2.1 million shares of our common stock under our Board-approved share repurchase program at a cost of $65 million (an average of $30.36 per share). As of June 30, 2018, the remaining authorization under our Board-approved share repurchase program was $325 million.

The following table sets forth our results of operations expressed as dollars and percentages of net sales. Figures are in millions, except percentages and per share amounts. Amounts may not add due to rounding differences.

Comparison of Three Months Ended June 30, 2018 with Three Months Ended July 1, 2017

Net sales

Net sales increased 11% to $316 million for the three months ended June 30, 2018, compared with $285 million for the same period one year ago. Net sales for the comparable period one year ago were affected by an approximately $25 million shift in sales from our second quarter to our third quarter as a result of a delay in deliveries and shipments related to an inventory shortage at a new supplier.

The 11% sales increase resulted from a 9% comparable sales increase in our Company-Controlled channel and 3 percentage points (ppt.) of growth from sales generated by 16 net new stores opened in the past 12 months.

The $32 million net sales increase compared with the same period one year ago was comprised of the following: (i) a $25 million increase in our Company-Controlled comparable net sales; and (ii) a $9 million increase resulting from net store openings; partially offset by (iii) a $2 million decrease in Wholesale/Other channel sales. Company-Controlled mattress unit sales increased 7% compared with the prior year. Average revenue per mattress unit in our Company-Controlled channel increased by 5% to $4,508.

The transition to our full line of Sleep Number 360^® smart beds continued during the quarter and is now complete. In May 2017, we began selling our i7 and i10 smart beds. We launched a third smart bed model (the p6) in December 2017. In April 2018, we introduced the Sleep Number 360 p5 and i8 smart beds, our two most popular models.

The Sleep Number 360 smart bed won 13 awards at CES 2017, including being named the Best of Innovation Honoree in the Home Appliance category. It also received the 2018 Edison Silver Award for breakthrough product design and innovation in the Wellness Technology category.

Gross profit

Gross profit of $189 million increased by $12 million, or 7%, compared with $177 million for the same period one year ago. The gross profit rate was 59.7% of net sales for the three months ended June 30, 2018, compared with 62.0% for the prior-year comparable period. The current-year gross profit rate decline of 2.3 ppt. was primarily due to: (i) 1.2 ppt. of temporary inefficiencies resulting from operating two product lines and closeout sales; and (ii) 1.1 ppt. mainly due to a higher mix of lower-margin sourced products, including FlexFit™ adjustable bases, and inflation impacts. These inefficiencies or transition costs included higher freight and logistics costs, and supplier transition expenses. In addition, our gross profit rate will fluctuate from quarter to quarter due to a variety of other factors, including warranty expenses, return and exchange costs, and performance-based incentive compensation.

Sales and marketing expenses

Sales and marketing expenses for the three months ended June 30, 2018 increased to $151 million, or 47.8% of net sales, compared with $144 million, or 50.8% of net sales, for the same period one year ago. The 3.0 ppt. decrease in the sales and marketing expense rate was mainly due to the leveraging impact of the 11% net sales increase (see net sales commentary above).

General and administrative expenses

General and administrative (G&A) expenses totaled $29 million, consistent with the prior-year period. During the three months ended June 30, 2018, a $0.6 million increase in employee compensation resulting primarily from salary and wage rate changes that were in line with inflation were offset by a decrease in miscellaneous other expenses. The G&A expense rate decreased by 1.0 ppt. to 9.1% of net sales in the current-year period compared with 10.1% for the same period one year ago due to the leveraging impact of the 11% net sales increase (see net sales commentary above).

Income tax benefit

Income tax benefit was $3.1 million for the three months ended June 30, 2018, compared with $2.6 million in the same period one year ago. The income tax benefit and effective income tax rate for the three months ended June 30, 2018 was impacted by changes associate with the Tax Cuts and Jobs Act, including a $2.9 million increase in the 2017 provisional tax benefit. See Note 12, Income Taxes, for further information.

Comparison of Six Months Ended June 30, 2018 with Six Months Ended July 1, 2017

Net sales

Net sales increased 4% to $705 million for the six months ended June 30, 2018, compared with $679 million for the same period one year ago. Net sales for the comparable period one year ago were affected by an approximately $25 million shift in sales from our second quarter to our third quarter as a result of a delay in deliveries and shipments related to an inventory shortage at a new supplier. The sales change was comprised of 3 percentage points (ppt.) of growth from sales generated by 16 net new stores opened in the past 12 months and a 2% comparable sales increase in our Company-Controlled channel, partially offset by a decrease in Wholesale/Other channel sales.

The $26 million net sales increase compared with the same period one year ago was comprised of the following: (i) an $18 million increase resulting from net store openings; and (ii) a $13 million increase in sales from our Company-Controlled comparable sales; partially offset by (iii) a $5 million decrease in Wholesale/Other channel sales. Company-Controlled mattress units decreased 2% compared to the prior-year period. Average revenue per mattress unit in our Company-Controlled channel increased by 7%.

Gross profit

Gross profit of $426 million for the six months ended June 30, 2018 increased by $3 million, or 1%, compared with $423 million for the same period one year ago. The gross profit rate decreased to 60.5% of net sales for the first six months of 2018, compared with 62.3% for the prior-year period. The current-year gross profit rate decline of 1.8 ppt. was primarily due to: (i) 1.1 ppt. from a higher mix of lower-margin sourced products, including FlexFit™ adjustable bases; and (ii) 0.7 ppt. resulting primarily from temporary inefficiencies resulting from operating two product lines and closeout sales. In addition, our gross profit rate will fluctuate from quarter to quarter due to a variety of other factors, including warranty expenses, return and exchange costs, and performance-based incentive compensation.

Sales and marketing expenses

Sales and marketing expenses for the six months ended June 30, 2018 increased to $323 million compared with $314 million for the same period one year ago, and decreased to 45.8% of net sales compared with 46.2% of net sales last year. The 0.4 ppt. decrease in the sales and marketing expense rate was mainly due to the leveraging impact of the 4% net sales increase (see net sales commentary above).

General and administrative expenses

General and administrative (G&A) expenses totaled $61 million, or 8.6% of net sales, for the six months ended June 30, 2018, compared with $63 million, or 9.2% of net sales, in the prior-year period. The $2 million decrease in G&A expenses consisted primarily of the following: (i) a $0.8 million decrease in employee compensation resulting from a year-over-year decrease in performance-based incentive compensation; and (ii) a $1.2 million net decrease in miscellaneous other expenses. The G&A expense rate decreased by 0.6 ppt. in the current-year period compared with the same period one year ago due to the decrease in expenses discussed above and leveraging impact of the 4% sales increase (see net sales commentary above).

Income tax expense

Income tax expense was $3 million for the six months ended June 30, 2018, compared with $9 million for the same period one year ago. The effective tax rate for the six months ended June 30, 2018 was 10.1% compared with 26.8% for the prior-year period reflecting the changes associate with the Tax Cuts and Jobs Act, including a $2.9 million increase in the 2017 provisional tax benefit. Both periods' tax expense and effective tax rates included stock-based compensation excess tax benefits. See Note 12, Income Taxes, for further information.

Liquidity and Capital Resources

Managing our liquidity and capital resources is an important part of our commitment to deliver superior shareholder value. Our primary sources of liquidity are cash flows provided by operating activities and cash available under our $300 million revolving credit facility. The cash generated from ongoing operations, and cash available under our revolving credit facility are expected to be adequate to maintain operations and fund anticipated expansion and strategic initiatives for the foreseeable future.

As of June 30, 2018, cash and cash equivalents totaled $2.4 million compared with $3.7 million as of December 30, 2017. Available borrowing capacity under our revolving credit facility was $114 million at June 30, 2018. The $1.2 million decrease in cash, cash equivalents and restricted cash was primarily due to $29 million of cash provided by operating activities and a $133 million increase in short-term borrowings, which was more than offset by $21 million of cash used to purchase property and equipment, and $143 million of cash used to repurchase our common stock ($140 million under our Board-approved share repurchase program and $3 million in connection with the vesting of employee restricted stock grants).

The following table summarizes our cash flows (dollars in millions). Amounts may not add due to rounding differences:



	Six Months Ended

Cash provided by operating activities for the six months ended June 30, 2018 was $29 million compared with $89 million for the six months ended July 1, 2017. Significant components of the year-over-year change in cash provided by operating activities included: (i) a $20 million fluctuation in accrued compensation and benefits that primarily resulted from year-over-year changes in company-wide performance-based incentive compensation that was accrued and paid in the two comparable periods (lower incentive compensation paid 2017; lower incentive compensation accrued in the first six months of 2018); (ii) a $19 million fluctuation in customer prepayments resulting mainly from higher than normal prepayments at July 1, 2017 (delayed deliveries and shipments due to an inventory shortage from one of our new suppliers); and (iii) an $11 million fluctuation in inventory resulting from temporarily higher than normal inventory levels at June 30, 2018 (to support the roll-out of new products, including our new Sleep Number 360 smart beds) and temporarily lower than normal inventory levels at July 1, 2017 (due to an inventory shortage from one of our new suppliers).

Net cash used in investing activities to purchase property and equipment was $21 million for the six months ended June 30, 2018, compared with $27 million for the same period one year ago.

Net cash used in financing activities was $9 million for the six months ended June 30, 2018, compared with $74 million for the same period one year ago. During the six months ended June 30, 2018, we repurchased $143 million of our stock ($140 million under our Board-approved share repurchase program and $3 million in connection with the vesting of employee restricted stock awards) compared with $80 million ($75 million under our Board-approved share repurchase program and $5 million in connection with the vesting of employee restricted stock awards) during the same period one year ago. Short-term borrowings increased by $133 million during the current-year period primarily due to the increase in borrowings under our revolving credit facility to $183 million, partially offset by a decrease in book overdrafts which are included in the net change in short-term borrowings.

Under our Board-approved share repurchase program, we repurchased 4.2 million shares at a cost of $140 million (an average of $33.22 per share) during the six months ended June 30, 2018. During the six months ended July 1, 2017, we repurchased 3.1 million shares at a cost of $75 million (an average of $24.57 per share). As of June 30, 2018, the remaining authorization under our Board-approved share repurchase program was $325 million. There is no expiration date governing the period over which we can repurchase shares.

In February 2018, we amended our revolving credit facility to increase our net aggregate availability from $153 million to $300 million. We maintained the accordion feature which allows us to increase the amount of the credit facility from $300 million to $450 million, subject to lenders' approval. There were no other changes to the credit agreement's terms and conditions.

Index

As of June 30, 2018, we had $183 million of borrowings under credit facility and $3 million in outstanding letters of credit. Our available borrowing capacity was $114 million. We were in compliance with all financial covenants. The credit facility matures in February 2023. The credit agreement provides the lenders with a collateral security interest in substantially all of our assets and those of our subsidiaries and requires us to comply with, among other things, a maximum leverage ratio and a minimum interest coverage ratio. Under the terms of the credit agreement we pay a variable rate of interest and a commitment fee based on our leverage ratio. The credit facility is for general corporate purposes and is utilized to meet our seasonal working capital requirements.

We have an agreement with Synchrony Bank to offer qualified customers revolving credit arrangements to finance purchases from us (Synchrony Agreement). The Synchrony Agreement contains financial covenants consistent with our credit facility, including a maximum leverage ratio and a minimum interest coverage ratio. As of June 30, 2018, we were in compliance with all financial covenants.

Under the terms of the Synchrony Agreement, Synchrony Bank sets the minimum acceptable credit ratings, the interest rates, fees and all other terms and conditions of the customer accounts, including collection policies and procedures, and is the owner of the accounts.

Non-GAAP Data

Earnings before Interest, Taxes, Depreciation and Amortization (Adjusted EBITDA)

We define earnings before interest, taxes, depreciation and amortization (Adjusted EBITDA) as net income plus: income tax expense, interest expense, depreciation and amortization, stock-based compensation and asset impairments. Management believes Adjusted EBITDA is a useful indicator of our financial performance and our ability to generate cash from operating activities. Our definition of Adjusted EBITDA may not be comparable to similarly titled definitions used by other companies. The table below reconciles Adjusted EBITDA, which is a non-GAAP financial measure, to the comparable GAAP financial measure.

Our Adjusted EBITDA calculations are as follows (dollars in thousands):



	Three Months Ended						Trailing-Twelve Months Ended

Free Cash Flow

Our “free cash flow” data is considered a non-GAAP financial measure and is not in accordance with, or preferable to, “net cash provided by operating activities,” or GAAP financial data. However, we are providing this information as we believe it facilitates analysis for investors and financial analysts.

The following table summarizes our free cash flow calculations (dollars in thousands):

Return on Invested Capital (ROIC)

(dollars in thousands)

ROIC is a financial measure we use to determine how efficiently we deploy our capital. It quantifies the return we earn on our invested capital. Management believes ROIC is also a useful metric for investors and financial analysts. We compute ROIC as outlined below. Our definition and calculation of ROIC may not be comparable to similarly titled definitions and calculations used by other companies. The tables below reconcile net operating profit after taxes (NOPAT) and total invested capital, which are non-GAAP financial measures, to the comparable GAAP financial measures:

___________________

⁽¹⁾ Rent expense is added back to operating income to show the impact of owning versus leasing the related assets.

⁽²⁾ Depreciation is based on the average of the last five fiscal quarters' ending capitalized operating lease obligations (see note 6) for the respective reporting periods with an assumed thirty-year useful life. This is subtracted from operating income to illustrate the impact of owning versus leasing the related assets.

⁽³⁾ Reflects annual effective income tax rates, before discrete adjustments, of 30.3% and 32.9% for 2018 and 2017, respectively.

⁽⁴⁾ Long-term debt includes existing capital lease obligations, if applicable. In conjunction with increasing our revolving credit facility to $300 million in the first quarter of 2018, we include borrowings under that agreement, including borrowings classified as short term.

⁽⁵⁾ A multiple of eight times annual rent expense is used as an estimate for capitalizing our operating lease obligations. The methodology utilized aligns with the methodology of a nationally recognized credit rating agency.

⁽⁶⁾ Average invested capital represents the average of the last five fiscal quarters' ending invested capital balances.

⁽⁷⁾ ROIC equals NOPAT divided by average invested capital.

Note - Our ROIC calculation and data are considered non-GAAP financial measures and are not in accordance with, or preferable to, GAAP financial data. However, we are providing this information as we believe it facilitates analysis of the Company's financial performance by investors and financial analysts.

Index

Off-Balance-Sheet Arrangements and Contractual Obligations

As of June 30, 2018, we were not involved in any unconsolidated special purpose entity transactions. Other than our operating leases and $3 million in outstanding letters of credit, we do not have any off-balance-sheet financing.

There has been no material changes in our contractual obligations, other than in the ordinary course of business, since the end of fiscal 2017. See Note 6, Credit Agreement, of the Notes to our Condensed Consolidated Financial Statements for information regarding our credit agreement. See our Annual Report on Form 10-K for the fiscal year ended December 30, 2017 for additional information regarding our other contractual obligations.

Critical Accounting Policies

We discuss our critical accounting policies and estimates in Management’s Discussion and Analysis of Financial Condition and Results of Operations in our Annual Report on Form 10-K for the fiscal year ended December 30, 2017. Other than the adoption of the new revenue recognition guidance as described in Note 1, Business and Summary of Significant Accounting Policies and Note 2, Revenue Recognition, there were no other significant changes in our critical accounting policies since the end of fiscal 2017.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to changes in market short-term interest rates that will impact our net interest expense. If overall interest rates were one percentage point higher than current rates, net income would decrease by $1.4 million based on the $183 million of borrowings under our revolving credit facility at June 30, 2018. We do not manage our investment interest-rate volatility risk through the use of derivative instruments.

ITEM 4. CONTROLS AND PROCEDURES

Conclusions Regarding the Effectiveness of Disclosure Controls and Procedures

We maintain disclosure controls and procedures, as defined in Exchange Act Rule 13a-15(e), that are designed to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms, and that such information is accumulated and communicated to the Company’s management, including its principal executive officer and principal financial officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this quarterly report. Based on this evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this quarterly report.

Changes in Internal Controls

There were no changes in our internal control over financial reporting during the fiscal quarter ended June 30, 2018, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II: OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

ITEM 1A. RISK FACTORS

Our business, financial condition and operating results are subject to a number of risks and uncertainties, including both those that are specific to our business and others that affect all businesses operating in a global environment. Investors should carefully consider the information in this report under the heading, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and also the information under the heading, “Risk Factors” in our most recent Annual Report on Form 10-K. The risk factors discussed in the Annual Report on Form 10-K and in this Quarterly Report on Form 10-Q do not identify all risks that we face because our business operations could also be affected by additional risk factors that are not presently known to us or that we currently consider to be immaterial to our operations.

Accounting Policies [Abstract]
Basis of Presentation	Business and Summary of Significant Accounting Policies Business & Basis of Presentation We prepared the condensed consolidated financial statements as of and for the three and six months ended June 30, 2018 of Sleep Number Corporation and 100%-owned subsidiaries (Sleep Number or the Company), without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) and they reflect, in the opinion of management, all normal recurring adjustments necessary to present fairly our financial position as of June 30, 2018 and December 30, 2017, and the consolidated results of operations and cash flows for the periods presented. Our historical and quarterly consolidated results of operations may not be indicative of the results that may be achieved for the full year or any future period. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (GAAP) have been condensed or omitted pursuant to such rules and regulations. These condensed consolidated financial statements should be read in conjunction with our most recent audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the fiscal year ended December 30, 2017 and other recent filings with the SEC. The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires us 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. Our critical accounting policies consist of stock-based compensation, goodwill and indefinite-lived intangible assets, warranty liabilities and revenue recognition. The condensed consolidated financial statements include the accounts of Sleep Number Corporation and our 100%-owned subsidiaries. All significant intra-entity balances and transactions have been eliminated in consolidation. New Accounting Pronouncements Recently Adopted Accounting Guidance Adoption of ASC Topic 230, Restricted Cash Effective December 31, 2017, we adopted ASC Topic 230, Restricted Cash, which requires amounts generally described as restricted cash and restricted cash equivalents be included with cash and cash equivalents when reconciling the total beginning and ending amounts for the periods shown on the statement of cash flows. Amounts for prior periods have been retrospectively adjusted to conform to the current period presentation. Adoption of ASC Topic 606, Revenue from Contracts with Customers On December 31, 2017, we adopted ASC Topic 606, Revenue from Contracts with Customers, using the modified retrospective method applied to those contracts which were not completed as of December 30, 2017. Results for reporting periods beginning after December 30, 2017 are presented under the new guidance, while prior period amounts are not restated. The cumulative effect of the changes made to our consolidated balance sheet as of December 31, 2017 resulting from the adoption of the new revenue guidance was not material and did not impact opening retained earnings. The impact on the timing of net sales for the three and six months ended June 30, 2018, as a result of applying the new guidance, was not material. Practical expedients and exemptions permissible under ASC Topic 606 that we elected are as follows: we do not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less; and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed. See Note 2, Revenue Recognition, for further details regarding our revenue recognition policy. Accounting Guidance Issued but Not Yet Adopted as of June 30, 2018 In February 2016, the FASB issued ASC Topic 842, Leases, that requires most leases to be recognized on the balance sheet and expands disclosure requirements. The provisions of this new guidance permit us to utilize a prospective approach, with elective reliefs. We are the lessee under various agreements for facilities and equipment that are currently accounted for as operating leases. This new guidance is effective for us beginning December 30, 2018 and we are in the process of implementing a new lease accounting system in connection with the adoption. While we expect a material impact to our consolidated balance sheet as a result of the adoption of this new guidance, we continue to evaluate the effect of the new standard on our consolidated financial statements and related disclosures. We also expect that adoption of the new guidance will require changes to our internal controls over financial reporting.

Fair Value Measurements	Jun. 30, 2018
Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements At June 30, 2018 and December 30, 2017, we had $5 million and $4 million, respectively, of debt and equity securities that fund our deferred compensation plan and are classified in other non-current assets. We also had corresponding deferred compensation plan liabilities of $5 million and $4 million at June 30, 2018 and December 30, 2017, respectively, which are included in other non-current liabilities. The majority of the debt and equity securities are Level 1 as they trade with sufficient frequency and volume to enable us to obtain pricing information on an ongoing basis. Unrealized gains/(losses) on the debt and equity securities offset those associated with the corresponding deferred compensation plan liabilities.

Profit Sharing and 401(k) Plan	Profit Sharing and 401(k) Plan Under our profit sharing and 401(k) plan, eligible employees may defer up to 50% of their compensation on a pre-tax basis, subject to Internal Revenue Service limitations. Each pay period, we may make a discretionary contribution equal to a percentage of the employee’s contribution. During the three months ended June 30, 2018 and July 1, 2017, our contributions, net of forfeitures, were $1.3 million and $1.2 million, respectively. During the six months ended June 30, 2018 and July 1, 2017, our contributions, net of forfeitures, were $2.7 million and $2.5 million, respectively.

Income Taxes [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes As a result of the enactment of the Tax Cuts and Jobs Act (TCJA), we recorded a provisional tax benefit of $1.7 million in the fourth quarter of 2017 based on our initial analysis of the TCJA using the best information and estimates available. During the second quarter 2018, we updated our provisional tax benefit based on new information, including a tax planning analysis, and recorded an additional $2.9 million provisional tax benefit. Due to the significant complexity of the TCJA, anticipated further guidance from the U.S. Treasury, the potential for additional guidance from the SEC/ FASB, or other new information becoming available, our provisional tax benefit may be further adjusted during 2018. Our provisional estimate is expected to be finalized no later than the fourth quarter of 2018. Further guidance and additional information regarding the TCJA may also impact our 2018 effective income tax rate, exclusive of any adjustment to the provisional tax benefit.

Revenue Recognition, Policy [Policy Text Block]	We recognize revenue when control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration we expect 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, we require payment before the products or services are delivered to the customer. Our beds sold with SleepIQ^® technology contain multiple performance obligations including the bed and SleepIQ’s hardware and software. We analyze our 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 the beds sold with the SleepIQ technology have two performance obligations consisting of: (i) the bed; and (ii) SleepIQ's hardware and software. SleepIQ’s 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. We determine 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 product’s estimated life of four years because our inputs are generally expended evenly throughout the performance period. At June 30, 2018 and December 30, 2017, we had deferred contract liabilities of $71 million and $73 million, of which $31 million and $30 million are included in other current liabilities, respectively, and $40 million and $43 million are included in other non-current liabilities, respectively, in our consolidated balance sheets. We also had deferred contract assets of $45 million and $43 million, of which $19 million and $17 million are included in other current assets, respectively, and $26 million and $26 million are included in other non-current assets, respectively, in our consolidated balance sheets. During the three and six months ended June 30, 2018, we recognized revenue of $8 million and $16 million, respectively, that was included in the deferred contract liability balance at the beginning of the period. Revenue from goods and services transferred to customers at a point in time accounted for approximately 97% and 98% of our revenues for the three and six months ended June 30, 2018, respectively. We accept sales returns during a 100-night trial period. Accrued sales returns represents a refund liability for the amount of consideration that we do 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 we remeasure the liability to reflect changes in the estimate, with a corresponding adjustment to net sales.
Stockholders' Equity, Policy	There is no expiration date governing the period over which we 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) retained earnings.
Profit Sharing and 401(k) Plan Policy	Under our profit sharing and 401(k) plan, eligible employees may defer up to 50% of their compensation on a pre-tax basis, subject to Internal Revenue Service limitations. Each pay period, we may make a discretionary contribution equal to a percentage of the employee’s contribution.
