Report of Independent Registered Public Accounting Firm
To the Plan Administrator and Participants of
Costco 401(k) Retirement Plan:
Opinion on the Financial Statements
We have audited the accompanying statement of net assets available for benefits of the Costco 401(k) Retirement Plan (the “Plan”) as of December 31, 2021 and 2020, the related statement of changes in net assets available for benefits for the year ended December 31, 2021, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2021 and 2020, and the changes in net assets available for benefits for the year ended December 31, 2021, in conformity with accounting principles generally accepted in the United States of America.
Basis for Opinion
These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on the Plan’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Plan in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Plan is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Plan’s internal control over financial reporting. Accordingly, we express no such opinion.
Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures to respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
Opinion on the Supplementary Information
The supplementary information included in Schedule H, line 4(i) – Schedule of Assets (Held at End of Year) as of December 31, 2021, have been subjected to audit procedures performed in conjunction with the audit of the Plan’s financial statements. The supplementary information is the responsibility of the Plan's management. Our audit procedures included determining whether the supplementary information reconciles to the financial statements or the underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplementary information. In forming our opinion on the supplementary information in the accompanying schedules, we evaluated whether the supplementary information, including its form and content, is presented in conformity with Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. In our opinion, the supplementary information in the accompanying schedules is fairly stated, in all material respects, in relation to the financial statements as a whole.

COSTCO 401(k) RETIREMENT PLAN
Notes to Financial Statements
December 31, 2021 and 2020
(1)Plan Description

The following description of the Costco 401(k) Retirement Plan (the Plan) provides only general information. Participants should refer to the Plan document for a more complete description of the Plan. To participate in the Plan, an individual must be an employee of Costco Wholesale Corporation (the Company or Costco) or certain subsidiaries.
The Plan is a defined contribution plan for the benefit of eligible employees, established by the Company under Section 401(a) of the Internal Revenue Code (IRC). It includes a qualified cash or deferred arrangement as described in Section 401(k). The Plan is also subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA), as amended.
(a)Employee Contributions

The Plan allows certain employees at least 18 years of age to make salary deferral contributions after completing 90 days of service within 12-consecutive months. Eligible employees may contribute from 1% to 50% of their compensation, subject to certain limitations set by the IRC and the Plan. Eligible employees may also contribute amounts representing certain distributions from other retirement plans (rollover contributions).
All newly-eligible employees are automatically enrolled in the Plan at a salary deferral contribution rate of 3%. The percentage deferred into the Plan automatically increases by one percentage point each year, to a maximum automatic deferral of 20%. Employees may opt out of automatic enrollment and increases.
(b)Employer Contributions

Company contributions are invested in accordance with selections made by participants. If no selection has been made, the contribution defaults to the Retirement Trust Fund corresponding to the participant's age. Employer contributions are allocated based on an employee’s classification as either: covered by the collective bargaining agreements with the International Brotherhood of Teamsters; or other eligible employment.
(1)    Covered by the Teamsters Agreements
The Company matches 50% of each employee’s contribution up to a maximum of $250 per year. Eligible employees at least 18 years of age who have completed one year of service (12 consecutive months) are eligible for an annual employer contribution and Plan entry dates for the employer contribution are January 1 and July 1. The annual employer contribution is allocated only to the accounts of eligible Plan participants who are employed on the last day of the applicable Plan year. The allocation rate varies, based on years of service, ranging from $0.05 to $0.47 per straight-time hour worked during the Plan year, up to a maximum of 2,080 hours. This annual contribution was $6.1 million for the year ended December 31, 2021, and was deposited into the Plan and allocated to participant accounts in March 2022.

Notes to Financial Statements (Continued)
December 31, 2021 and 2020
(2)    Other eligible employment
The Company matches 50% of each employee’s contribution up to a maximum of $500 per year. In addition, eligible employees at least 18 years of age who have completed one year of service (12 consecutive months) are eligible for an annual discretionary employer contribution and Plan entry dates for the discretionary contribution are January 1 and July 1. The discretionary contribution is allocated only to the accounts of eligible Plan participants who are employed on the last day of the applicable Plan year. The allocation rate varies, based on years of service, ranging from 3% to 9% of the participant's compensation. This discretionary contribution was $436.7 million for the year ended December 31, 2021, and was deposited into the Plan and allocated to participant accounts in March 2022.
(c)Participants’ Accounts

Each participant’s account is credited or debited with the participant’s contributions, the Company’s contributions, earnings, fees, expenses, and changes in underlying account assets. The benefit to which a participant is entitled is the vested account balance.
(d)Vesting

Participants are immediately vested in their deferral contributions and in certain other contributions as defined in the Plan document, adjusted for investment experience, fees and expenses. Vesting in any form of employer contribution is based on the following schedule:
Years of servicePercentage vested
Under 2 years0%
2 years20%
3 years40%
4 years60%
5 years100%
(e)Forfeitures

If a participant terminates employment, the non-vested portion of the account balance is forfeited. Forfeited amounts are used to reduce future employer contributions or to pay administrative expenses. These were immaterial during 2021. There were no unallocated forfeitures as of December 31, 2021 and 2020, after consideration of forfeitures used to reduce the employer contributions funded subsequent to each year. Forfeitures are restored to a participant’s account if within five years the participant is re-hired and repays the vested account balance distributed upon termination.
(f)Investment Options

Participants may direct funds in their account to the Plan's available options. Participants may transfer amounts between investment options daily, subject to certain trading restrictions. Before 2016, participants could invest 100% of their account in Costco stock; starting January 2016, the Plan has a 50% limit on investment in Costco stock, applied prospectively.
Amounts may be temporarily invested in a cash account prior to investment in the Plan’s investment accounts. See Notes 2, 3 and 4 for additional information regarding the Plan's investments.

COSTCO 401(k) RETIREMENT PLAN
Notes to Financial Statements (Continued)
December 31, 2021 and 2020
(g)Distributions

Upon termination of employment, total disability, reaching age 59-1/2 or death, a participant (or participant's beneficiary in the case of death) can request a full, partial or, in certain circumstances, installment or rollover distribution for the vested portion of the account. Participants are also eligible to withdraw a portion of the salary-deferral contribution account in the event of certain financial hardships.
Dividends on the Company's stock are reinvested in the participant’s Company stock account unless a distribution is requested by the participant. These dividends are reported on a gross basis, with total dividends reported as “Dividends” and the amounts distributed reported as “Distributions to participants and other” in the statement of changes in net assets available for benefits.
(h)Notes Receivable from Participants

A participant may borrow between $1,000 up to the lesser of $50,000 or 45% of their vested account balance, reduced by the highest outstanding balance in the previous 12 months, provided this amount is available in the participant's pre-tax and rollover accounts. Loans are repaid through payroll deductions over a period ranging up to four years or, if for the purchase of a principal residence, up to 15 years. The bi-weekly re-payment amount cannot exceed 25% of the participant's net pay. The interest rate is determined by the Plan Administrator from time-to-time and is comparable to rates charged by commercial lenders. At December 31, 2021, interest rates on loans outstanding ranged from 4.25% to 10.25%, with various maturities through December 2036. Participant accounts with loans are charged an application fee at initiation and an annual maintenance fee.
(i)Trustee and Plan Administrator

T. Rowe Price Trust Company is the trustee and recordkeeper for the Plan, and the Costco Benefits Committee is the Plan Administrator.
(j)Administrative and Investment Expenses

Certain administrative expenses, including investment management and transaction fees, are paid by the Plan, subject to subparagraph (e) above. All other administrative expenses are paid by the Company.


(2)Summary of Significant Accounting Policies

(a)Basis of Accounting

The financial statements of the Plan are prepared under the accrual method of accounting. As required under U.S. generally accepted accounting principles (U.S. GAAP), fully benefit-responsive investment contracts (FBRIC) are reported at contract value (see Note 3), while all other investments in the Plan are reported at fair value (see Note 4). A benefit-responsive investment contract is a contract with a financial institution or an insurance company that provides for a stated return on principal invested over a specified period and permits withdrawals at contract value for benefit payments, loans, or transfers to other investment options offered to the participant by the Plan. Contract value is the amount participants would receive if they were to initiate permitted transactions under the terms of the Plan.

COSTCO 401(k) RETIREMENT PLAN
Notes to Financial Statements (Continued)
December 31, 2021 and 2020
(b)Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates and assumptions.
(c)Investment Valuation and Income Recognition

The Plan invests in the Company’s common stock, common commingled trust funds and other exchange-traded equity securities held in separately managed accounts, as well as registered investment companies and a FBRIC.
Investments, other than the FBRIC, are reported at fair value. If available, quoted market prices are used to value investments. The FBRIC consists of the Capital Preservation Portfolio (CPP), which is invested in synthetic guaranteed investment contracts and is recorded at contract value. Contract value represents contributions made under each contract, plus earnings, less participant withdrawals and administrative expenses.
There are no reserves against contract value for credit risk of the contract issuer or otherwise. The crediting interest rate is based on a formula agreed upon with the issuer, but may not be less than zero. Such interest rates are reviewed on a quarterly basis for resetting. Certain events may limit the ability of the Plan to transact at contract value with the issuer. Events may include, but are not limited to, Plan termination, bankruptcy of the Company, or defunction of the trustee. In addition, certain events allow the issuer to terminate the contract with the Plan and settle at an amount different from contract value. Examples of such events include the following: (1) an uncured violation of the Plan’s investment guidelines, (2) a breach of material obligation under the contract, (3) a material misrepresentation, or (4) a material amendment to the agreements without the consent of the issuer. The Plan Administrator believes at this time that any events that would limit the Plan’s ability to transact at contract value with participants or that allow the issuer to terminate the contract with the Plan are not probable.
Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on an accrual basis. Dividends are recorded on the ex-dividend date. Net appreciation or depreciation of investments includes the change in the fair value of assets from one period to the next, plus realized gains and losses.
Investment securities are exposed to various risks, such as interest rate, credit, and overall market volatility. Changes in the values of investment securities could occur, and those changes could materially affect the amounts reported in the statements of net assets available for benefits.
(d)Notes Receivable from Participants

Participant loans are classified as notes receivable from participants, which are segregated from Plan investments and measured at their unpaid principal balance plus any accrued but unpaid interest. Delinquent notes receivable are reclassified as distributions based upon the terms of the Plan document.
(e)Distribution of Benefits

Distributions of benefits are recorded when paid.

COSTCO 401(k) RETIREMENT PLAN
Notes to Financial Statements (Continued)
December 31, 2021 and 2020
(f)     Subsequent Events

The Plan monitors significant events occurring after the statement of net assets available for benefits date and prior to the issuance of the financial statements to determine the impacts, if any, on the financial statements to be issued. The Plan has evaluated subsequent events through the date which the financial statements are issued.

The Plan was amended on January 1, 2021, to increase the automatic enrollment contribution rate for employees who become eligible for salary deferral contributions after March 31, 2022.

(3)Fully Benefit-Responsive Investment Contract

The CPP is invested in synthetic guaranteed investment contracts, which consist of a portfolio of underlying assets owned by the Plan and wrap contracts issued by an insurance company and a financial institution. The issuers of the wrap contracts provide for unscheduled withdrawals from the contracts at contract value, regardless of the value of the underlying assets, in order to fund routine withdrawals.

(4)Fair Value Measurement

U.S. GAAP defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is estimated by applying a fair value hierarchy, which requires maximizing the use of observable inputs. The three levels of inputs are:
Level 1: Quoted market prices in active markets for identical assets or liabilities.
Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data.
Level 3: Significant unobservable inputs that are not corroborated by market data.
The asset or liability's fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques maximize the use of relevant observable inputs and minimize the use of unobservable inputs. Valuation techniques utilized during the reporting period were not changed from previous practice. The following is a description of the valuation methodologies used for assets measured at fair value.
Common stock, underlying securities in separately managed accounts, and registered investment company funds: These investments are deemed to be actively traded and are valued at the closing price reported in the active market in which the individual securities are traded. These assets are valued using Level 1 inputs. Mutual funds held by the Plan are open-end mutual funds that are registered with the U.S. Securities and Exchange Commission. Separately managed accounts largely consist of common stock.
8

COSTCO 401(k) RETIREMENT PLAN
Notes to Financial Statements (Continued)
December 31, 2021 and 2020
Common commingled trust funds: The valuation techniques used to measure the fair value of common commingled trust funds are based on quoted market prices, such as quoted net asset values (NAV) published by the fund as supported in an active market. Plan participant transactions of investment or withdrawals may occur on a daily basis in these trusts. These assets are valued using Level 1 inputs.
The tables below present information regarding investments that are measured at fair value on a recurring basis and indicate the level within the hierarchy reflecting the valuation techniques utilized to determine fair value as of December 31, 2021 and 2020.

Separately managed accounts3,354,012 
Registered investment company funds1,895,869 
Total investments in fair value hierarchy$21,761,136 
(5)Plan Termination

Although it has no present intent to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan, subject to ERISA and the requirements of the collective bargaining agreements with the International Brotherhood of Teamsters. In the event of termination, participants will become 100% vested in their accounts.
(6)Commitments and Contingencies

On June 23, 2020, a putative class action was filed against the Company, the "Board of Directors," the "Costco Benefits Committee" and others under the Employee Retirement Income Security Act, in the United States District Court for the Eastern District of Wisconsin. Dustin S. Soulek v. Costco Wholesale, et al., Case No. 20-cv-937. The class is alleged to be beneficiaries of the Costco 401(k) plan from June 23, 2014, and the claims are that the defendants breached their fiduciary duties in the operation and oversight of the plan. The complaint seeks injunctive relief, damages, interest, costs, and attorneys' fees. On September 11, 2020, the defendants filed a motion to dismiss the complaint, and on September 21 the plaintiffs filed an amended complaint, which the defendants moved to dismiss. On March 17, 2022, the court granted preliminary approval of a class-wide settlement, under which the defendants will pay an immaterial amount. A hearing to consider final approval of the settlement is scheduled for July 18, 2022.

COSTCO 401(k) RETIREMENT PLAN
Notes to Financial Statements (Continued)
December 31, 2021 and 2020
(7)Tax Status

In a determination letter dated June 9, 2017, the IRS informed the Company that the Plan is designed in accordance with applicable sections of the IRC. The Plan has been restated and amended since receiving the determination letter. The Plan Administrator believes that the Plan is designed and is being operated in compliance with the IRC.
U.S. GAAP requires the Plan Administrator to evaluate tax positions taken by the Plan and recognize a tax liability (or asset) if the Plan has taken an uncertain position that more likely than not would not be sustained upon examination by the IRS. The Plan Administrator has concluded that as of December 31, 2021, there are no uncertain positions taken or expected to be taken that would require recognition of a liability (or asset) or disclosure in the financial statements. The Plan is subject to routine audits by taxing jurisdictions; there are currently no audits in progress.
(8)Party-in-Interest and Related Party Transactions

Certain Plan investments are shares of registered investment companies, benefit-responsive investment contracts, and common commingled trust funds managed by T. Rowe Price Trust Company. T. Rowe Price is also the trustee and recordkeeper as defined by the Plan, therefore these transactions qualify as exempt party-in-interest transactions.
As the Plan sponsor, the Company is a party-in-interest with respect to the Plan. As of December 31, 2021 and 2020, the Plan held 26,278,000 and 27,232,000 shares of Costco common stock.
