Summary of Significant Accounting Policies | NOTE 1 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The Partnership’s Business and Basis of Accounting. The accompanying Consolidated Financial Statements include the accounts of The Jones Financial Companies, L.L.L.P. and all wholly-owned subsidiaries (collectively, the “Partnership” or "JFC"). The financial position of the Partnership’s subsidiaries in Canada as of November 30, 2023 and 2022 are included in the Partnership's Consolidated Statements of Financial Condition and the results for the twelve month periods ended November 30, 2023, 2022 and 2021 are included in the Partnership’s Consolidated Statements of Income, Consolidated Statements of Changes in Partnership Capital Subject to Mandatory Redemption and Consolidated Statements of Cash Flows because of the timing of the Partnership’s financial reporting process. The Partnership’s principal operating subsidiary, Edward D. Jones & Co., L.P. (“Edward Jones”), is a registered broker-dealer and investment adviser in the United States (“U.S.”), and Edward Jones (an Ontario limited partnership), is a registered broker-dealer in Canada ("EJ Canada"). Through these entities, the Partnership primarily serves individual investors in the U.S. and Canada. Edward Jones is a retail brokerage business and primarily derives revenues from fees for providing investment advisory and other account services to its clients, fees for assets held by clients and commissions for the distribution of mutual fund shares and insurance products and the purchase or sale of securities. The Partnership conducts business throughout the U.S. and Canada with its clients, various brokers, dealers, clearing organizations, depositories and banks. For financial information related to the Partnership’s two operating segments for the years ended December 31, 2023, 2022 and 2021, see Note 15 to the Consolidated Financial Statements. Trust services are offered to Edward Jones’ U.S. clients through Edward Jones Trust Company (“Trust Co.”), a wholly-owned subsidiary of the Partnership. Olive Street Investment Advisers, LLC ("Olive Street"), a wholly-owned subsidiary of the Partnership, provides investment advisory services to the Edward Jones Money Market Fund (the "Money Market Fund") and the twelve sub-advised mutual funds comprising the Bridge Builder® Trust ("BB Trust"). The Consolidated Financial Statements have been prepared on the accrual basis of accounting in conformity with U.S. generally accepted accounting principles (“GAAP”), which require the use of certain estimates by management in determining the Partnership’s assets, liabilities, revenues and expenses. Actual results could differ from these estimates. Certain prior period balances have been adjusted to align to current year presentation. The Partnership evaluated subsequent events for recognition or disclosure through the date these Consolidated Financial Statements were issued and identified no matters requiring disclosure other than those disclosed in Note 14. Partnership Agreement. Under the terms of the Partnership’s Twenty-Second Amended and Restated Agreement of Registered Limited Liability Limited Partnership, dated August 15, 2023, (the “Partnership Agreement”), a partner’s capital is required to be redeemed by the Partnership in the event of the partner’s death or withdrawal from the Partnership, subject to compliance with ongoing regulatory capital requirements. In the event of a partner’s death, the Partnership generally redeems the partner’s capital within six months . The Partnership has restrictions in place which govern the withdrawal of capital. Under the terms of the Partnership Agreement, limited partners requesting withdrawal from the Partnership are repaid their capital in three equal annual installments beginning no earlier than 90 days after their withdrawal notice is received by the Managing Partner (as defined in the Partnership Agreement). The capital of general partners requesting withdrawal from the Partnership is converted to subordinated limited partnership capital or, at the discretion of the Managing Partner, redeemed by the Partnership. Subordinated limited partners requesting withdrawal are repaid their capital in six equal annual installments beginning no earlier than 90 days after their request for withdrawal of capital is received by the Managing Partner. The Managing Partner has discretion to waive or modify these withdrawal restrictions and to accelerate the return of capital. All current and future Partnership capital is subordinate to all current and future liabilities of the Partnership. The Partnership Agreement includes additional terms. Revenue Recognition. The Partnership's revenue is recognized based on contracts with clients, mutual fund companies, insurance companies and other product providers. As a full-service brokerage firm, Edward Jones and EJ Canada provide clients with custodial services, including safekeeping of client funds, collecting and disbursing funds from a client's account, and providing trade confirmations and account statements. The Partnership does not charge a separate fee for these services. Revenue is generally recognized in the same manner for both the U.S. and Canada segments. The Partnership classifies its revenue into the following categories: Asset-based fee revenue – Revenue is derived from fees determined by the underlying value of client assets and includes advisory programs fees, service fees, and other asset-based fee revenue. The primary source of asset-based fee revenue is generated from program fees for investment advisory services. Advisory program contracts outline the investment advisory services to be performed for a client under the contract and do not have a definite end date. Program fees are based on the average daily market value of client assets in the program as well as contractual rates and are charged to clients monthly and collected the following month. The investment advisory services performed in an advisory program contract are a series of distinct services that are substantially the same and have the same pattern of transfer to the client. As a result, the contract has one performance obligation, and program fee revenue is recognized over time as clients simultaneously receive and consume the benefit from the investment advisory services performed by the Partnership. The Partnership's contracts with mutual fund and insurance companies, along with the prospectuses for mutual funds, allow the Partnership to sell those companies' products to clients (see Trade revenue below for the associated commissions earned from clients) and earn service fees for providing certain distribution and marketing support services for those companies' products held by Edward Jones clients. For mutual funds, those service fees are based on the terms of the mutual fund prospectuses. Service fees are generally based on the average daily market value of client assets held in a company's mutual fund or insurance product. For future service fees the Partnership may earn on existing client assets, market constraints prevent reasonably estimating the transaction price and estimates could result in significant revenue reversals. Thus, service fee revenue is recognized monthly at the time the market constraints have been removed, the transaction price is known and the services have been performed. Other asset-based fee revenue consists of revenue sharing, fund adviser fees, cash solutions and Trust Co. fees. The Partnership has agreements with clients or product providers to earn other asset-based fees for providing services, which generally include providing investment advice or service to clients or mutual funds, or marketing support or other services to product providers. Additionally, Edward Jones earns cash solutions revenue from the Edward Jones Insured Bank Deposit Program (the "IBD Program"), which is an interest-bearing savings solution for clients that offers Federal Deposit Insurance Corporation (“FDIC”) insurance coverage. Edward Jones has agreements with FDIC-insured third-party banks to transfer available cash balances in participating clients' accounts to interest-bearing deposit accounts at those banks. Edward Jones, as agent, earns net revenue from fees derived from the average daily deposit balance in the IBD Program. Other asset-based fees are generally based on asset values held in clients' accounts. The services performed for other asset-based fee contracts are a series of distinct services that are substantially the same and have the same pattern of transfer to the client. As a result, the contracts have one performance obligation, and revenue is recognized over time as the customer simultaneously receives and consumes the benefit from the services performed by the Partnership. For both service fees and other asset-based fee revenue, revenue is collected monthly or quarterly based on the agreements and the agreements generally do not have a term. Due to the timing of receipt of information, the Partnership uses estimates in recording the accruals related to certain asset-based fees, which are based on historical trends and are adjusted to reflect market conditions for the period covered. Account and activity fee revenue – Revenue is derived from fees based on the number of accounts or activity and includes shareholder accounting services fees, self-directed individual retirement account ("IRA") fees, and other activity-based fee revenue from clients, mutual fund companies and insurance companies. The Partnership has agreements with mutual fund companies for shareholder accounting services in which the Partnership performs certain transfer agent support services, which may include tracking client holdings, distributing dividends and shareholder information to clients, and responding to client inquiries. Shareholder accounting services fees are based on the number of mutual fund positions held by clients and fees are collected monthly or quarterly based on the agreements, which generally do not have a term. The transfer agent support services performed in a shareholder accounting services contract are a series of distinct services that are substantially the same and have the same pattern of transfer to the client. As a result, the contract has one performance obligation, and revenue is recognized over time as the mutual fund company simultaneously receives and consumes the benefit from the services performed by the Partnership. The Partnership also earns retirement account fees for providing reporting services pursuant to the Internal Revenue Code and account maintenance services. Clients are charged an annual fee per account for these services. Revenue is recognized over a one-year period as the services are provided, which are simultaneously received and consumed by the client. Trade revenue – Revenue is derived from fees based on client transactions and includes commissions and principal transactions. The primary source of trade revenue is from commissions revenue which consists of charges to clients for the distribution of mutual fund shares and insurance products and the purchase or sale of securities. Principal transactions revenue primarily results from the Partnership’s distribution of and participation in principal trading activities in municipal obligations, certificates of deposit and corporate obligations. Principal transactions are generally entered into by the Partnership to facilitate a client's buy or sell order for certain fixed income products. Brokerage contracts outline the transaction services to be performed for a client under the contract and do not have a term. The transaction charge to clients varies based on the product and size of the trade. The Partnership's contracts with mutual fund and insurance companies, along with the prospectuses for mutual funds, allow the Partnership to sell those companies' products to clients and earn certain commissions, which for mutual funds, are aligned with the terms of the mutual fund prospectuses. Trade revenue is recognized at a point in time when the transaction is placed, or trade date. On trade date the client obtains control through a right to either own a security for a purchase or receive payment for a sale. Transaction charges are received no later than settlement date . Interest and dividends revenue – Interest and dividends revenue is earned on client margin loan balances, cash and cash equivalents, cash and investments segregated under federal regulations, securities purchased under agreements to resell, Partnership loans and investment securities, none of which is based on revenue contracts with clients. Other revenue (loss), net – Other revenue (loss), net, primarily consists of unrealized gains and losses associated with changes in the fair market value of the Partnership's investment securities held to generate income and to assist in the management of Firm liquidity, as well as securities held to economically hedge future liabilities for its non-qualified deferred compensation plan. Unrealized gains and losses are impacted by changes in market levels and the interest rate environment. All revenues are recorded on an accrual basis. For forms of revenue not specifically discussed above, asset-based revenue is recorded over time as the services are provided, and activity or transaction-based revenue is recorded at a point in time when the transaction occurs. Foreign Exchange. Assets and liabilities denominated in a foreign currency are translated at the exchange rate at the end of the period. Revenue and expenses denominated in a foreign currency are translated using the average exchange rate for each period. Foreign exchange gains and losses are included in other revenue (loss), net on the Consolidated Statements of Income. Fair Value. Substantially all of the Partnership’s financial assets and financial liabilities covered under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) No. 820, Fair Value Measurement and Disclosure (“ASC 820”), are carried at fair value or at contracted amounts which approximate fair value given the short time to maturity. Fair value of a financial instrument is defined 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, also known as the “exit price.” Financial assets are marked to bid prices and financial liabilities are marked to offer prices. The Partnership’s financial assets and financial liabilities recorded at fair value in the Consolidated Statements of Financial Condition are categorized based upon the level of judgment associated with the inputs used to measure their fair value. Hierarchical levels, defined by ASC 820, with the related amount of subjectivity associated with the inputs to value these assets and liabilities at fair value for each level, are as follows: Level I – Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. The types of assets categorized as Level I generally are government and agency obligations, including U.S. treasuries, investments in publicly traded mutual funds and money market funds with quoted market prices, equities listed in active markets and client fractional share ownership assets. The types of liabilities categorized as Level I are client fractional share redemption obligations. Level II – Inputs (other than quoted prices included in Level I) are either directly or indirectly observable for the asset or liability through correlation with related market data at the measurement date and for the duration of the instrument’s anticipated life. The Partnership uses the market approach valuation technique which incorporates third-party pricing services and other relevant observable information (such as market interest rates, yield curves, prepayment risk and credit risk generated by market transactions involving identical or comparable assets or liabilities) in valuing these types of investments. When third-party pricing services are used, the methods and assumptions used are reviewed by the Partnership. The types of assets categorized as Level II generally are certificates of deposit, municipal obligations and corporate bonds and notes. Level III – Inputs are both unobservable and significant to the overall fair value measurement. These inputs reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the inputs to the model. The Partnership did no t have any assets or liabilities categorized as Level III during the years ended December 31, 2023 and 2022 . Cash and Cash Equivalents. The Partnership considers all highly liquid investments with maturities of three months or less from the purchase date to be cash equivalents. Cash and Investments Segregated under Federal Regulations. Cash, investments and interest receivable related to the investments are segregated in special reserve bank accounts for the benefit of U.S. clients pursuant to the Customer Protection Rule 15c3-3 under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Collateral. The Partnership does not report collateral it has received in secured lending and other arrangements as an asset when the debtor has the right to redeem or substitute the collateral on short notice. Fractional Shares. Clients may receive fractional share interests through the Partnership's dividend reinvestment and dollar cost averaging programs. The Partnership records these fractional shares, which are considered encumbered assets, at fair value in other assets with associated liabilities in accounts payable, accrued expenses and other in the Consolidated Statements of Financial Condition as the Partnership must fulfill its clients' future fractional share redemptions. The liabilities are initially recorded at the dollar amount received from the clients, but the Partnership makes an election to record the liabilities at fair value. Changes in the fair value of the assets and liabilities offset in other revenue (loss), net in the Consolidated Statements of Income, with no impact on income before allocations to partners. Securities Owned . Securities owned, primarily consisting of investment securities, are recorded on a trade-date basis at fair value which is determined by using quoted market or dealer prices. Investment securities, which are primarily held to generate income, also assist in the management of Firm liquidity. The unrealized gains and losses for investment securities are recorded in other revenue (loss), net in the Consolidated Statements of Income. The Partnership also purchases and holds inventory securities for retail sales to its clients but does not trade those positions for the purpose of generating gains for its own account. The related unrealized gains and losses for inventory securities are recorded in trade revenue in the Consolidated Statements of Income. Fixed Assets. Fixed Assets include buildings and leasehold improvements, equipment, software, and land. Buildings are depreciated using the straight-line method over their useful lives, which are estimated at thirty years . Leasehold improvements are amortized based on the term of the lease or the economic useful life of the improvement, whichever is less. Equipment, including furniture and fixtures, is recorded at cost and depreciated using straight-line and accelerated methods over estimated useful lives of three to seven years . Software includes purchased software licenses and internally developed software. Internally developed software consists of labor and consulting costs to develop and implement new software or modify existing software to improve functionality for the Partnership's internal use, while costs in other project phases are expensed as incurred. Software is depreciated using the straight-line method over its useful life, which is estimated at three to five years . The cost of maintenance and repairs is charged against income as incurred, whereas significant enhancements are capitalized and depreciated once the asset is placed into service. When assets are retired or otherwise disposed of, the cost and related accumulated depreciation or amortization is removed from the respective category and any related gain or loss is recorded as other revenue (loss), net in the Consolidated Statements of Income. Fixed assets are reviewed for impairment whenever events or changes in circumstances indicate that the book value of the asset may not be fully recoverable. If impairment is indicated, the asset value is written down to its fair value. Non-qualified Deferred Compensation Plan. The Partnership has a non-qualified deferred compensation plan for certain financial advisors. The Partnership has recorded a liability of $ 261 for the future payments due to financial advisors participating in the plan. As the future amounts due to financial advisors change in accordance with plan requirements, the Partnership records the change in future amounts owed to financial advisors as an increase or decrease in accrued compensation in the Consolidated Statements of Financial Condition and compensation and benefits expense in the Consolidated Statements of Income. The Partnership has chosen to economically hedge this future liability by purchasing securities in an amount similar to the future liability expected to be due in accordance with the plan. These securities are included in investment securities in the Consolidated Statements of Financial Condition and the unrealized gains and losses are recorded in other revenue (loss), net in the Consolidated Statements of Income. Each period, the net impact of the change in future amounts owed to financial advisors in the plan and the change in value of the investment securities are approximately the same, resulting in minimal net impact to the Consolidated Financial Statements. Retirement Transition Plans. The Partnership, in certain circumstances, offers individually tailored retirement transition plans to retiring financial advisors. Each retirement transition plan compensates a retiring financial advisor for successfully providing client transition services in accordance with a retirement and transition agreement. Generally, the retirement and transition agreement is for five years . During the first two years the retiring financial advisor remains an employee and provides client transition services, which include, but are not limited to, the successful transition of client accounts and assets to successor financial advisors, as well as mentoring and providing training and support to successor financial advisors. The financial advisor retires at the end of year two and is subject to a non-compete agreement for three years . Most retiring financial advisors participating in a retirement transition plan are paid ratably over four years . Compensation expense is generally recognized ratably over the two-year transition period which aligns with the service period of most agreements, with compensation expense related to some plans recognized over one year depending on the size and complexity of the transition plan. As of December 31, 2023, $ 150 was accrued for future payments to financial advisors who have already started a plan, approximately $ 62 of which is expected to be paid in 2024. As of December 31, 2022, $ 113 was accrued. Successor financial advisors in the program receive reduced compensation on transitioned assets for up to five years . Lease Accounting. The Partnership leases branch office space under numerous operating leases from non-affiliates and financial advisors. Branch offices are generally leased for terms of five years and generally contain a renewal option. Renewal options are not included in the lease term if it is not reasonably certain the Partnership will exercise the renewal option. The Partnership also leases a home office space and land from non-affiliates with terms ranging from 12 to 30 years . The Partnership recognizes lease liabilities for future lease payments and lease right-of-use assets for the right of use of an underlying asset within a contract. Current leases are all classified as operating leases. Lease right-of-use assets and lease liabilities are recognized in the Consolidated Statements of Financial Condition at commencement date and calculated as the present value of the sum of the remaining fixed lease payments over the lease term. Throughout the lease term, the lease right-of-use asset includes the impact from the timing of lease payments and straight-line rent expense. The Partnership used its incremental borrowing rate based on information available at lease commencement as leases do not contain a readily determinable implicit rate. A single lease cost, or rent expense, is recognized on a straight-line basis over the lease term. The Partnership does not separate lease components (i.e., fixed payments including rent, real estate taxes and insurance costs) from non-lease components (i.e., common-area maintenance) and recognizes them as a single lease component. Variable lease payments not included within lease contracts are expensed as incurred. See Note 2 for additional information. Advertising. Advertising activities include the cost to produce and distribute campaigns market wide to attract and retain clients and financial advisors. Such costs are generally expensed when incurred. Income Taxes. Generally, income taxes have not been provided for in the Consolidated Financial Statements due to the partnership tax structure where each partner is liable for their own tax payments. For the jurisdictions in which the Partnership is liable for tax payments, the income tax provisions are immaterial (see Note 11). Partnership Capital Subject to Mandatory Redemption. FASB ASC No. 480, Distinguishing Liabilities from Equity (“ASC 480”), established standards for classifying and measuring certain financial instruments with characteristics of both liabilities and equity. Under the provisions of ASC 480, the obligation to redeem a partner’s capital in the event of a partner’s death is one of the criteria requiring capital to be classified as a liability. Since the Partnership Agreement obligates the Partnership to redeem a partner’s capital after a partner’s death, ASC 480 requires all of the Partnership’s equity capital to be classified as a liability. In accordance with ASC 480, income allocable to limited, subordinated limited and general partners is classified as a reduction of income before allocations to partners, which results in a presentation of zero net income for the years ended December 31, 2023, 2022 and 2021. The financial statement presentations required to comply with ASC 480 do not alter the Partnership’s treatment of income, income allocations or capital for any other purposes. Net Income, as defined in the Partnership Agreement, is equivalent to income before allocations to partners on the Consolidated Statements of Income. Such income, if any, for each calendar year is allocated to the Partnership’s three currently outstanding classes of capital in accordance with the formulas prescribed in the Partnership Agreement. Income allocations are based upon partner capital contributions including capital contributions financed with loans from the Partnership. First, limited partners are allocated Net Income in accordance with the prescribed formula for their share of net income. Limited partners generally do not share in the Net Loss, as defined in the Partnership agreement, in any year in which there is a net loss and the Partnership is not dissolved or liquidated. Thereafter, subordinated limited partners and general partners are allocated any remaining Net Income or Net Loss based on formulas as defined in the Partnership Agreement. The limited partnership capital subject to mandatory redemption is held by current and former associates and general partners of the Partnership. Limited partners participate in the Partnership’s profits and are paid a minimum 7.5 % annual return on the face amount of their capital (see Note 9) in accordance with the Partnership Agreement. The subordinated limited partnership capital subject to mandatory redemption is held by current and former general partners of the Partnership. Subordinated limited partners receive a percentage of the Partnership’s Net Income determined in accordance with the Partnership Agreement. The subordinated limited partnership capital subject to mandatory redemption is subordinated to the limited partnership capital. The general partnership capital subject to mandatory redemption is held by current general partners of the Partnership. General partners receive a percentage of the Partnership’s Net Income determined in accordance with the Partnership Agreement. The general partnership capital subject to mandatory redemption is subordinated to the limited partnership capital and the subordinated limited partnership capital. Current Expected Credit Losses . The Partnership individually assessed the current expected credit loss for the assets below. Receivables from Clients Receivables from clients is primarily composed of margin loan balances. The value of securities owned by clients and held as collateral for these receivables is not reflected in the Consolidated Financial Statements. Collateral held as of December 31, 2023 and 2022 was $ 4,231 and $ 5,094 , respectively, and was not repledged or sold. The Partnership considers these financing receivables to be of good credit quality due to the fact that these receivables are primarily collateralized by the related client investments. To estimate expected credit losses on margin loans, the Partnership applied the collateral maintenance practical expedient by comparing the amortized cost basis of the margin loans with the fair value of collateral at the reporting date. Margin loans are limited to a fraction of the total value of the securities held in the client's account against those loans upon issuance in accordance with Financial Industry Regulatory Authority (“FINRA”) rules. In the event of a decline in the market value of the securities in a margin account, the Partnership requires the client to deposit additional securities or cash (or to sell a sufficient amount of securities) so that, at all times, the loan to the client is no greater than 65 % of the value of the securities in the account, which is a more stringent maintenance requirement than FINRA Rule 4210. As such, the Partnership reasonably expects that the borrower will be able to continually replenish collateral securing the financial asset and does not expect the fair value of collateral to fall below the value of margin loans and, as a result, the Partnership considers credit risk related to these receivables to be minimal. The fair value of collateral was higher than the amortized cost basis for virtually all margin loans as of December 31, 2023 and 2022 , and the expected credit loss for those loans was zero for each period. In limited circumstances, a margin loan may become undercollateralized. When this occurs, the Partnership records a reserve for the undercollateralized portion of the loan, which was an immaterial amount as of December 31, 2023 and 2022. Securities Purchased under Agreements to Resell The Partnership participates in short-term resale agreements collateralized by government and agency securities. These transactions are reported as collateralized financing and are carried at contractual cost with accrued interest in receivable from mutual funds, insurance companies and other within the Consolidated Statements of Financial Condition. The fair value of the underlying collateral, plus accrued interest, must equal or exceed 102 % of the carrying amount of the transaction in U.S. agreements and must equal or exceed 100 % of the carrying amount of the transaction in Canada agreements. In the event that the fair value of the collateral does not meet the contractual minimums, the counterparty is obligated to meet any shortfall promptly. It is the Partnership’s policy to have such underlying resale agreement collateral delivered to the Partnership or deposited in its accounts at its custodian banks. The fair value of the collateral related to these agreements was $ 1,158 and $ 441 as of December 31, 2023 and 2022, respectively, and was not repledged or sold. To estimate expected credit losses on the resale agreements, the Partnership applied the collateral |
