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 months ended April 3, 2021 of Sleep Number Corporation and our 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 April 3, 2021 and January 2, 2021, 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. Additionally, based on the duration and severity of the current global situation involving the novel coronavirus (COVID-19) pandemic, including but not limited to general economic conditions, consumer confidence, store closings mandated by federal, state or local authorities and possible supply chain disruptions, the extent to which COVID-19 will impact our business and our consolidated financial results will depend on future developments, which are highly uncertain and cannot be predicted.
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 January 2, 2021 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. In addition, during the current environment involving COVID-19, predicting future events will be especially challenging for management. 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.
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.
2. Fair Value Measurements
At April 3, 2021 and January 2, 2021, we had $16 million and $12 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 $16 million and $12 million at April 3, 2021 and January 2, 2021, 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.
3. Inventories
Inventories consisted of the following (in thousands):

| April 3, 2021 |  | January 2, 2021
Raw materials | $ | 10,496 |  |  | $ | 12,599 |
Work in progress | 88 |  |  | 103 |

Definite-lived Intangible Assets
The gross carrying amount of our developed technologies was $19 million at April 3, 2021 and January 2, 2021. Accumulated amortization was $14 million and $13 million at April 3, 2021 and January 2, 2021, respectively. Amortization expense for both the three months ended April 3, 2021 and March 28, 2020, was $0.5 million.
The gross carrying amount of our patents, which were acquired in June 2020, was $2 million at April 3, 2021 and January 2, 2021, respectively.

5. Credit Agreement
Our credit facility as of April 3, 2021, had a net aggregate availability of $450 million. The credit facility is for general corporate purposes, to meet our seasonal working capital requirements and to repurchase our stock. The credit agreement provides the lenders with a collateral security interest in substantially all of our assets and those of our subsidiaries and requires us to comply with, among other things, a maximum leverage ratio (4.5x) and a minimum interest coverage ratio (3.0x). Under the terms of the credit agreement, we pay a variable rate of interest and a commitment fee based on our leverage ratio. We were in compliance with all financial covenants as of April 3, 2021.
The following table summarizes our borrowings under the credit facility ($ in thousands):

| April 3, 2021 |  | January 2, 2021
Outstanding borrowings | $ | 314,900 |  |  | $ | 244,200 |
Outstanding letters of credit | $ | 3,997 |  |  | $ | 3,997 |
Additional borrowing capacity | $ | 131,103 |  |  | $ | 201,803 |
Weighted-average interest rate | 1.5 | % |  | 1.5 | %

On April 21, 2021, we amended our revolving credit facility to increase our net aggregate availability from $450 million to $600 million. We maintained the accordion feature which allows us to increase the amount of the credit facility from $600 million to $800 million, subject to lenders’ approval. The amended credit facility matures in February 2024. There were no other significant changes to the credit facility’s terms and conditions.

6. Leases
We lease our retail, office and manufacturing space under operating leases which, in addition to the minimum lease payments, may require payment of a proportionate share of the real estate taxes and certain building operating expenses. While our local market development approach generally results in long-term participation in given markets, our retail store leases generally provide for an initial lease term of five to 10 years. Our office and manufacturing leases provide for an initial lease term of up to 15 years. In addition, our mall-based retail store leases may require payment of variable rent based on net sales in excess of certain thresholds. Certain leases may contain options to extend the term of the original lease. The exercise of lease renewal options is at our sole discretion. Lease options are included in the lease term only if exercise is reasonably certain at lease commencement. Our lease agreements do not contain any material residual value guarantees. We also lease vehicles and certain equipment under operating leases with an initial lease term of three to five years.
Our operating lease costs include facility, vehicle and equipment lease costs, but exclude variable lease costs. Operating lease costs are recognized on a straight-line basis over the lease term, after consideration of rent escalations and rent holidays. The lease term for purposes of the calculation begins on the earlier of the lease commencement date or the date we take possession of the property. During lease renewal negotiations that extend beyond the original lease term, we estimate straight-line rent expense based on current market conditions. Variable lease costs are recorded when it is probable the cost has been incurred and the amount can be reasonably estimated. Future payments for real estate taxes and certain building operating expenses for which we are obligated are not included in operating lease costs.
At April 3, 2021, our finance right-of-use assets and lease liabilities were not significant.

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 U.S. generally accepted accounting principles, 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. If a material loss is reasonably possible but not known or probable, and may be reasonably estimated, the estimated loss or range of loss is disclosed. With respect to currently pending legal proceedings, we have not established an estimated range of reasonably possible material losses either because we believe that we have valid defenses to claims asserted against us, the proceeding has not advanced to a stage of discovery that would enable us to establish an estimate, or the potential loss is not material. We currently do not expect the outcome of pending legal proceedings 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 September 18, 2018, two former Home Delivery team members filed suit, now venued in San Diego County Superior Court, California, alleging representative claims on a purported class action basis under the California Labor Code Private Attorney General Act. While the two representative plaintiffs were in the Home Delivery workforce, the Complaint does not limit the purported plaintiff class to that group. The plaintiffs allege that Sleep Number failed or refused to adopt adequate practices, policies and procedures relating to wage payments, record keeping, employment disclosures, meal and rest breaks, among other claims, under California law. The Complaint sought damages in the form of civil penalties and plaintiffs’ attorneys’ fees. The parties have executed a settlement agreement, including the settlement and release of certain additional related claims that are contained in a consolidated complaint,

which received preliminary Court approval on July 29, 2020. On January 8, 2021, the Court granted final approval of the parties' settlement and any right to appeal the final approval expired on April 6, 2021. Sleep Number has satisfied its obligations under the settlement and all that remains are the administrative steps related to the distribution to be performed by the claims administrator.
On March 27, 2018, Level Sleep, LLC (Level Sleep) filed a patent infringement lawsuit against Sleep Number in the Federal District Court for the Eastern District of Texas. In its Complaint, Level Sleep claims that Sleep Number infringed two patents owned by Level Sleep, U.S. Patent Nos. 6,807,698 and 7,036,172 (the Patents), by, among other things, making, using, offering for sale, or selling within the United States, and/or importing into the United States, beds with sleep surfaces having foam with multiple zones in the longitudinal direction. Level Sleep has asserted that five non-360® beds no longer sold and two current non-360 beds infringe the Patents. Level Sleep seeks damages in the form of a reasonable royalty. Sleep Number has asserted that the Patents are invalid and that our products do not infringe the Patents. On January 14, 2020, the Court granted summary judgment in favor of Sleep Number, finding that Sleep Number’s products do not infringe the Patents. Level Sleep has filed an appeal of the Court’s summary judgment order, which was heard by the Federal Circuit Court of Appeals on January 5, 2021, and we are awaiting a decision. We intend to continue vigorously defending this matter.
13. COVID-19 Pandemic
At the onset of the COVID-19 pandemic in mid-March 2020, government restrictions resulted in the temporary closure of most of our retail stores, with 47% of our stores closed on average during the second quarter of 2020. While prioritizing the safety of our team, serving our customers and ensuring business continuity, we swiftly took decisive actions to strengthen our liquidity, cash flows and financial position, and mitigate the future impact on our operations and financial performance.
The pandemic mainly impacted our second quarter of 2020 financial performance, as we generated strong financial performance during the full-year of 2020 and the first quarterly period ended April 3, 2021. However, the pandemic's future effect on consumer demand and our ongoing financial performance remains uncertain. See Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations and Part II: Item 1A. Risk Factors for additional discussion on the COVID-19 pandemic and the impact on our business.

COVID-19 Pandemic - Impact on our Business
At the onset of the COVID-19 pandemic in mid-March 2020, government restrictions resulted in the temporary closure of most of our retail stores, with 47% of our stores closed on average during the second quarter of 2020. While prioritizing the safety of our team, serving our customers and ensuring business continuity, we swiftly took decisive actions to strengthen our liquidity, cash flows and financial position, and mitigate the future impact on our operations and financial performance.
The pandemic mainly impacted our second quarter of 2020 financial performance, as we generated strong financial performance during the full-year of 2020 and the first quarterly period ended April 3, 2021. However, the pandemic's future effects on consumer demand and our ongoing financial performance remains uncertain. See Part I: Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations and Part II: Item 1A. Risk Factors for additional discussion on the COVID-19 pandemic and the impact on our 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, 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, timing of new product introductions and related expenses, timing of promotional offerings, competitive factors, changes in commodity costs, disruptions in supplies or third-party service providers, seasonality of retail and bedding industry sales, consumer confidence and general economic conditions. In addition, based on the duration and severity of the current global situation involving the COVID-19 pandemic, the extent to which our business and our condensed consolidated financial results are impacted, will depend on future developments, which are highly uncertain and cannot be predicted. 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 three months ended April 3, 2021 were as follows:
•Net sales for the three months ended April 3, 2021 increased 20% to $568 million, compared with $473 million for the same period one year ago.
•The 20% net sales increase included a 20% comparable sales increase in Total Retail, including strong growth in online, phone and chat sales. For additional details, see the components of total net sales change on page 15.
•Sales per store (sales for stores open at least one year, Total Retail, including online, phone and chat sales) on a trailing twelve-month basis for the period ended April 3, 2021 totaled $3.2 million, 9% higher than the same period last year.
•Operating income for the three months ended April 3, 2021 was $76 million, an increase of $24 million, or 45%, compared with $53 million in the prior-year period. The $24 million increase in operating income was driven by the 20% increase in net sales and
13

a 3.6 percentage points (ppt.) reduction in our operating expenses rate, partially offset by a 1.3 ppt. decrease in the gross profit rate.
•The gross profit rate decrease of 1.3 ppt. was primarily due to reinstated incentive compensation (minimal incentive compensation was recorded in the first quarter of 2020 based on the economic uncertainty related to the pandemic), and inflationary cost pressures and higher supply chain costs associated with temporary supply constraints, partially offset by the leverage from the 20% net sales increase.
•The 3.6 ppt. reduction in our operating expenses rate was mainly due to the leveraging impact of the 20% net sales increase. During the three months ended April 3, 2021, we continued to prioritize investments in near- and long-term growth drivers, including $13.3 million of R&D expenses, 27% more than the same period one year ago.
•Net income for the three months ended April 3, 2021 increased by 70% to $67 million, compared with net income of $39 million for the same period one year ago. Net income per diluted share was $2.51, an 85% increase compared with net income per diluted share of $1.36 last year.
•We achieved a return on invested capital (ROIC) of 27.6% on a trailing twelve-month basis for the period ended April 3, 2021, compared with 19.1% for the comparable period one year ago.
•Cash provided by operating activities for the three months ended April 3, 2021 increased by $27 million, or 31%, to $112 million, compared with $85 million for the same period one year ago.
•At April 3, 2021, we had $315 million of borrowings under our revolving credit facility. Net liquidity available under our revolving credit facility was $131 million at April 3, 2021.
•On April 21, 2021, we amended our revolving credit facility to expand the aggregate availability from $450 million to $600 million. We also replenished our outstanding share repurchase authorization to $600 million effective at the beginning of the fiscal second quarter, April 4, 2021. We remain committed to our capital deployment priorities focused on performance drivers.
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 April 3, 2021 with Three Months Ended March 28, 2020
Net sales
Net sales for the three months ended April 3, 2021 increased by $96 million, or 20%, to $568 million, compared with $473 million for the same period one year ago.
The 20% net sales increase consisted primarily of a 20% comparable sales increase in Total Retail. For additional details, see the components of total net sales change on page 15. Online, phone and chat sales (included in comparable sales noted above) made up 14% of total net sales compared with 8% in the prior year as consumers embrace transacting remotely with Sleep Number as well as in our stores.
The $96 million net sales increase compared with the same period one year ago was comprised of the following: (i) a $90 million increase in our Total Retail comparable net sales; and (ii) a $6 million increase from net store openings. Total Retail mattress unit sales increased 17% compared with the prior year. Total Retail average revenue per mattress unit increased by 3% to $5,030, compared with $4,884 in the prior-year period.
Gross profit
Gross profit of $356 million increased by $54 million, or 18%, compared with $302 million for the same period one year ago. The gross profit rate was 62.6% of net sales for the three months ended April 3, 2021, compared with 63.9% for the prior-year comparable period. The current-year gross profit rate decrease of 1.3 ppt. was mainly due to: (i) increased performance-based incentive compensation expense (0.5 ppt.; minimal incentive compensation was recorded in the first quarter of 2020 based on the economic uncertainty related to the pandemic); (ii) inflationary cost pressures and higher supply chain costs associated with temporary supply constraints (0.5 ppt.); and (iii) other miscellaneous items, including product mix (0.6 ppt.); partially offset by (iv) leverage from the 20% net sales increase (0.3 ppt.). In addition, our gross profit rate will fluctuate from quarter to quarter due to a variety of other factors, including return and exchange costs.
Sales and marketing expenses
Sales and marketing expenses for the three months ended April 3, 2021 were $224 million, or 39.4% of net sales, compared with $208 million, or 44.0% of net sales, for the same period one year ago. The current-year sales and marketing expenses rate decrease of 4.6 ppt. was primarily due to: (i) the leveraging impact of the 20% net sales increase; and (ii) efficiency gains through our digital ecosystem and operating initiatives. Efficiency gains and operating initiatives included leveraging our media spending, which increased by 17% compared with the prior year, while net sales increased by 20%, and improved store operating productivity.
General and administrative expenses
General and administrative (G&A) expenses totaled $43 million, or 7.5% of net sales, for the three months ended April 3, 2021, compared with $31 million, or 6.6% of net sales, in the prior-year period. The $12 million increase in G&A expenses consisted primarily of: (i) a $13.9 million increase in employee compensation primarily resulting from a year-over-year increase in company-wide performance-based incentive compensation (minimal incentive compensation was recorded in the first quarter of 2020 based on the economic uncertainty related to the pandemic); partially offset by (ii) a $2.4 million decrease in travel expenses and other miscellaneous expenses. The G&A expenses rate increased by 0.9 ppt. in the current-year period, compared with the same period one year ago due to the items discussed above, partially offset by the leveraging impact of the 20% net sales increase.
Research and development expenses
Research and development (R&D) expenses increased by 27% to $13.3 million for the three months ended April 3, 2021, compared with $10.5 million for the same period last year as we continued to prioritize our long-term innovation initiatives.
Interest expense, net
Interest expense, net decreased to $1.0 million for the three months ended April 3, 2021, compared with $2.3 million for the same period one year ago. The $1.4 million decrease was mainly driven by a lower level of outstanding borrowings during the three months ended April 3, 2021 and a decrease in the weighted-average interest rate on borrowings, compared with the same period one year ago.
16

Income tax expense
Income tax expense totaled $9 million for the three months ended April 3, 2021, compared with $11 million last year. The effective income tax rate for the three months ended April 3, 2021 was 11.7%, compared with 22.4% for the comparable period last year, reflecting stock-based compensation excess tax benefits of $10 million in the current-year period compared with approximately $1 million last year.
Liquidity and Capital Resources
Managing our liquidity and capital resources is an important part of our commitment to deliver superior shareholder value over time. Our primary sources of liquidity are cash flows provided by operating activities and cash available under our $600 million revolving credit facility (increased from $450 million to $600 million as of April 21, 2021). 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.
Changes in cash and cash equivalents during the three months ended April 3, 2021 primarily consisted of $112 million of cash provided by operating activities and a $74 million net increase in short-term borrowings, offset by $12 million of cash used to purchase property and equipment, and $179 million of cash used to repurchase our common stock (based on settlement, $162 million under our Board-approved share repurchase program and $17 million in connection with the vesting of employee restricted stock grants).
The following table summarizes our cash flows ($ in millions). Amounts may not add due to rounding differences:

| Three Months Ended
| April 3, 2021 |  | March 28, 2020
Total cash provided by (used in): |  |  |
Operating activities | $ | 111.6 |  |  | $ | 84.9 |
Investing activities | (11.5) |  |  | (10.3) |
Financing activities | (102.1) |  |  | 163.0 |
Net (decrease) increase in cash and cash equivalents | $ | (2.0) |  |  | $ | 237.6 |

Cash provided by operating activities for the three months ended April 3, 2021 was $112 million, compared with $85 million for the three months ended March 28, 2020. Significant components of the year-over-year change in cash provided by operating activities included: (i) a $27 million increase in net income for the three months ended April 3, 2021, compared with the same period one year ago; (ii) a $29 million fluctuation in customer prepayments due to strong customer demand during the three months ended April 3, 2021 and temporary supply constraints which extended customer delivery timelines; (iii) a $21 million fluctuation in the amount of compensation and benefits accrued and timing of the related payments resulting from year-over-year changes in Company-wide performance-based incentive compensation; and (iv) an $11 million fluctuation in prepaid expenses and other assets due to both periods being impacted by the timing of rent payments and prior-year changes in business activities due to the pandemic.
Net cash used in investing activities to purchase property and equipment was $12 million for the three months ended April 3, 2021, compared with $10 million for the same period one year ago. The year-over-year increase was due to higher property and equipment purchases for new and remodeled stores.
Net cash used in financing activities was $102 million for the three months ended April 3, 2021, compared with net cash provided by of $163 million for the same period last year. During the three months ended April 3, 2021, we repurchased $179 million of our stock (based on settlement dates, $162 million under our Board-approved share repurchase program and $17 million in connection with the vesting of employee restricted stock awards), compared with $41 million during the same period one year ago. Short-term borrowings increased by $74 million during the current-year period due to a $71 million increase in borrowings under our revolving credit facility to $315 million and a $3 million increase in book overdrafts which are included in the net change in short-term borrowings. Short-term borrowings increased by $201 million during the prior-year period due to a $215 million increase in borrowings under our revolving credit facility based on uncertainty related to the pandemic, partially offset by a decrease in book overdrafts.
Under our Board-approved share repurchase program, we repurchased 1.2 million shares at a cost of $167 million (based on trade dates, an average of $136.27 per share) during the three months ended April 3, 2021. During the three months ended March 28, 2020, we repurchased 0.8 million shares at a cost of $38 million (based on trade dates, an average of $49.42 per share). There is no expiration date governing the period over which we can repurchase shares. Effective as of April 4, 2021, our Board approved an increase in our total remaining share repurchase authorization to $600 million.
17

As of April 3, 2021, we had $315 million of borrowings under our revolving credit facility. We also had $4 million in outstanding letters of credit. Net liquidity available under our credit facility was $131 million at April 3, 2021. 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 (4.5x) and a minimum interest coverage ratio (3.0x). Our leverage ratio as defined in our credit agreement was 2.3x as of April 3, 2021. 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 is for general corporate purposes, to meet our seasonal working capital requirements and to repurchase our stock. As of April 3, 2021, the weighted-average interest rate on borrowings under the credit facility was 1.5% and we were in compliance with all financial covenants.
On April 21, 2021, we amended our revolving credit facility to increase our net aggregate availability from $450 million to $600 million. We maintain the accordion feature which allows us to increase the amount of the credit facility from $600 million to $800 million, subject to lenders’ approval. The amended credit facility matures in February 2024. There were no other significant changes to the credit facility’s terms and conditions.
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 consistent with our credit agreement. As of April 3, 2021, 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. As the accounts are owned by Synchrony Bank, at no time are the accounts purchased or acquired from us. We are not liable to Synchrony Bank for our customers’ credit defaults.

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 life assumption is based on our long-term participation in given markets though specific retail location lease commitments are generally 5 to 10 years at inception. 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 23.9% for both 2021 and 2020.
(4)Cash greater than target is defined as cash, cash equivalents and marketable debt securities less customer prepayments in excess of $100 million.
(5)Long-term debt includes existing finance lease liabilities.
(6)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.
(7)Average invested capital represents the average of the last five fiscal quarters' ending invested capital balances.
(8)ROIC equals NOPAT divided by average invested capital.

Off-Balance-Sheet Arrangements and Contractual Obligations
As of April 3, 2021, we were not involved in any unconsolidated special purpose entity transactions. Other than our $4 million in outstanding letters of credit, we do not have any off-balance-sheet financing.
There have been no material changes in our contractual obligations, other than the amendments to our credit agreement, since the end of fiscal 2020. See Note 5, 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 January 2, 2021 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 January 2, 2021. There were no significant changes in our critical accounting policies since the end of fiscal 2020.
ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
We are exposed to changes in market-based short-term interest rates that will impact our net interest expense. If overall interest rates were one percentage point higher than current rates, our annual net income would decrease by $2.4 million based on the $315 million of borrowings under our credit facility at April 3, 2021. We do not manage the interest-rate volatility risk of borrowings under our credit facility 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 Control
There were no changes in our internal control over financial reporting during the fiscal quarter ended April 3, 2021, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
