Accounting Policies [Abstract] |
Principles of Consolidation | Principles of Consolidation The Company consolidates entities in which it has a controlling financial interest. The Company determines whether it has a controlling financial interest in an entity by first evaluating whether the entity is a variable interest entity ("VIE") or a voting interest entity. VIEs are entities in which (i) the total equity investment at risk is not sufficient to enable the entity to finance its activities independently or (ii) the at-risk equity holders do not have the normal characteristics of a controlling financial interest. A controlling financial interest in a VIE is present when an enterprise has one or more variable interests that have both (i) the power to direct the activities of the VIE that most significantly impact the VIE's economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. The enterprise with a controlling financial interest is the primary beneficiary and consolidates the VIE. Voting interest entities lack one or more of the characteristics of a VIE. The usual condition for a controlling financial interest is ownership of a majority voting interest for a corporation or a majority of kick-out or participating rights for a limited partnership. When the Company does not have a controlling financial interest in an entity but exerts significant influence over the entity's operating and financial policies, the Company's investment is accounted for under the equity method of accounting. If the Company does not have a controlling financial interest in, or exert significant influence over, an entity, the Company accounts for its investment at fair value, if the fair value option was elected, or at cost.
Cash and Cash Equivalents | Cash and Cash Equivalents Cash and cash equivalents consist of cash and highly liquid investments with maturities of 90 days or less at the date of origination.
Fair Value of Financial Instruments | Fair Value of Financial Instruments Financial instruments and other inventory positions owned and financial instruments and other inventory positions sold, but not yet purchased on the consolidated statements of financial condition consist of financial instruments (including securities with extended settlements and derivative contracts) recorded at fair value. Unrealized gains and losses related to these financial instruments are reflected on the consolidated statements of operations. Securities (both long and short), including securities with extended settlements, are recognized on a trade-date basis. Additionally, the Company's investments on the consolidated statements of financial condition are principally recorded at fair value. Fair Value Measurement – Definition and Hierarchy Financial Accounting Standards Board ("FASB") Accounting Standards Codification Topic 820, "Fair Value Measurement," ("ASC 820") defines fair value as the amount at which an instrument could be exchanged in an orderly transaction between market participants at the measurement date (i.e., the exit price). ASC 820 establishes a fair value hierarchy based on the inputs used to measure fair value. The fair value hierarchy maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from independent sources. Unobservable inputs reflect management's assumptions that market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The hierarchy is broken down into three levels based on the observability of inputs as follows: Level I – Quoted prices (unadjusted) are available in active markets for identical assets or liabilities as of the report date. A quoted price for an identical asset or liability in an active market provides the most reliable fair value measurement because it is directly observable to the market. Level II – Pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the report date. The nature of these financial instruments include instruments for which quoted prices are available but traded less frequently, instruments whose fair value has been derived using a model where inputs to the model are directly observable in the market, or can be derived principally from or corroborated by observable market data, and instruments that are fair valued using other financial instruments, the parameters of which can be directly observed. Level III – Instruments that have little to no pricing observability as of the report date. These financial instruments are measured using management's best estimate of fair value, where the inputs into the determination of fair value require significant management judgment or estimation. Valuation of Financial Instruments Based on the nature of the Company's business and its role as a "dealer" in the securities industry or as a manager of alternative asset management funds, the fair values of its financial instruments are determined internally. When available, the Company values financial instruments at observable market prices, observable market parameters, or broker or dealer prices (i.e., bid and ask prices). In the case of financial instruments transacted on recognized exchanges, the observable market prices represent quotations for completed transactions from the exchange on which the financial instrument is principally traded. A substantial percentage of the fair value of the Company's financial instruments and other inventory positions owned and financial instruments and other inventory positions sold, but not yet purchased, is based on observable market prices, observable market parameters, or derived from broker or dealer prices. The availability of observable market prices and pricing parameters can vary from product to product. Where available, observable market prices and pricing or market parameters in a product may be used to derive a price without requiring significant judgment. In certain markets, observable market prices or market parameters are not available for all products, and fair value is determined using techniques appropriate for each particular product. These techniques involve some degree of judgment. Results from valuation models and other techniques in one period may not be indicative of future period fair value measurement. For investments in illiquid or privately held securities that do not have readily determinable fair values, the determination of fair value requires the Company to estimate the value of the securities using the best information available. Among the factors considered by the Company in determining the fair value of such financial instruments are the cost, terms and liquidity of the investment, the financial condition and operating results of the issuer, the quoted market price of publicly traded securities with similar quality and yield, and other factors generally pertinent to the valuation of investments. In addition, even where the Company derives the value of a security based on information from an independent source, certain assumptions may be required to determine the security's fair value. For instance, the Company assumes that the size of positions in securities that it holds would not be large enough to affect the quoted price of the securities if the Company sells them, and that any such sale would happen in an orderly manner. The actual value realized upon disposition could be different from the currently estimated fair value.
Investments | Investments The Company's investments include equity investments in private companies and partnerships, as well as mutual funds related to deferred compensation plans. Equity investments in private companies and mutual funds related to deferred compensation plans are accounted for at fair value. Investments in partnerships are accounted for under the equity method, which is generally the net asset value.
Fixed Assets | Fixed Assets Fixed assets include furniture and equipment, software, and leasehold improvements. Furniture and equipment and software are depreciated using the straight-line method over estimated useful lives of three to ten years. Leasehold improvements are amortized over 15 years or the life of the lease, whichever is shorter.
Leases | Leases A lease is a contract, or part of a contract, that conveys the right to control the use of identified property or equipment for a period of time in exchange for consideration. The Company determines if a contract contains a lease at inception. The Company leases its corporate headquarters and other offices under various non-cancelable leases, all of which are operating leases. In addition to rent, the leases require payment of real estate taxes, insurance and common area maintenance. Some of the leases contain renewal and/or termination options, escalation clauses, rent-free holidays and operating cost adjustments. The original terms of the Company's lease agreements generally range up to 15 years. The Company recognizes a right-of-use ("ROU") lease asset and lease liability on the consolidated statements of financial condition for leases with a term greater than 12 months. The lease liability represents the Company’s obligation to make future lease payments and is recorded at an amount equal to the present value of the remaining lease payments due over the lease term. The ROU lease asset, which represents the right to use the underlying asset during the lease term, is measured based on the carrying value of the lease liability, adjusted for lease incentives and uneven rent payments. The discount rate used to determine the present value of the remaining lease payments reflects the Company’s incremental borrowing rate, which is the rate the Company would have to pay to borrow on a collateralized basis over a similar term in a similar economic environment. In calculating its discount rates, the Company takes into consideration financing arrangements that are on a secured (i.e., collateralized) basis, as well as market interest rates and spreads, other reference points, and the respective tenors of the Company’s designated lease term ranges. The Company applies the portfolio approach in determining the discount rates for its leases. The Company recognizes rent expense on a straight-line basis from the date it takes possession of the property to the end of the initial lease term. Lease incentives are recognized on a straight-line basis as a reduction of rent expense over the lease term. Rent expense for leases with a term of 12 months or less is recorded on a straight-line basis over the lease term in the consolidated statements of operations.
Goodwill and Intangible Assets | Goodwill and Intangible Assets Goodwill represents the fair value of the consideration transferred in excess of the fair value of identifiable net assets at the acquisition date. The Company tests goodwill and indefinite-lived intangible assets for impairment on an annual basis and on an interim basis when circumstances exist that could indicate possible impairment. The Company tests goodwill for impairment at the reporting unit level, which is generally one level below its operating segment. The Company has identified one reporting unit. When testing for impairment, the Company has the option to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after making an assessment, the Company determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then further analysis is unnecessary. However, if the Company concludes otherwise, then the Company is required to perform a quantitative goodwill test, which requires management to make judgments in determining what assumptions to use in the calculation. The quantitative goodwill test compares the fair value of the reporting unit to its carrying value, including allocated goodwill. An impairment is recognized for the excess amount of a reporting unit's carrying value over its fair value. The estimated fair value of the reporting unit is derived based on valuation techniques that a market participant would use. The Company estimates the fair value of the reporting unit using the income approach (e.g., discounted cash flow method) and market approach (e.g., earnings and/or transaction multiples). At December 31, 2025, intangible assets with determinable lives consisted of customer relationships that are amortized over their original estimated useful lives ranging from one to eight years. The pattern of amortization reflects the timing of the realization of the economic benefits of such intangible assets. Indefinite-lived intangible assets, which are not amortized, are evaluated for impairment annually, at a minimum, or on an interim basis if events or circumstances indicate a possible inability to realize the carrying amount.
Other Assets | Other Assets Other assets include receivables and prepaid expenses. Receivables primarily include installment fee receivables, fee receivables and loans made to employees, typically in connection with their recruitment. Installment fee receivables are related to the Company's private fund placement services and are generally paid in installments over a period of two to four years. Fee receivables are primarily related to the Company's advisory services and are generally collected within 30 days. Employee loans are forgiven based on continued employment and are amortized to compensation and benefits expense using the straight-line method over the respective terms of the loans, which generally range from one to five years. The Company estimates the allowance for credit losses using relevant available information from internal and external sources relating to historical credit loss experience, current economic conditions and reasonable and supportable forecasts that could potentially affect the collectibility of the reported amounts.
Contingencies | Contingencies The Company is involved in various pending and potential legal proceedings related to its business, including litigation, arbitration and regulatory proceedings. The Company establishes accruals for potential losses to the extent that claims are probable of loss and the amount of the loss can be reasonably estimated. The determination of the outcome and accrual amounts requires significant judgment on the part of the Company's management.
Revenue Recognition | Revenue Recognition See Note 17 for revenues from contracts with customers disaggregated by major business activity. Investment Banking Investment banking revenues, which include advisory and underwriting fees, are recorded when the performance obligation for the transaction is satisfied under the terms of each engagement. Expenses associated with such transactions are deferred until the related revenue is recognized or the engagement is otherwise concluded. Investment banking revenues are presented gross of related client reimbursed deal expenses. Expenses for completed deals are reported separately in deal-related expenses on the consolidated statements of operations. Expenses related to investment banking deals not completed are recognized as non-interest expenses in their respective category on the consolidated statements of operations. The Company's advisory fees generally consist of a nonrefundable up-front fee and a success fee. The nonrefundable fee is recorded as deferred revenue upon receipt and recognized at a point in time when the performance obligation is satisfied, or when the transaction is deemed by management to be terminated. Management's judgment is required in determining when a transaction is considered to be terminated. Certain engagements, such as restructuring advisory transactions, consist of services provided on an ongoing basis, and the fees are recognized over time as the performance obligation is satisfied. Fees related to the private fund placement services are recognized at a point in time as the performance obligation is satisfied upon the closing date of the committed capital. The substantial majority of the Company's advisory and underwriting fees (i.e., the success-related advisory fee) is considered variable consideration and recognized when it is probable that the variable consideration will not be reversed in a future period. The variable consideration is considered to be constrained until satisfaction of the performance obligation. The Company's performance obligation is generally satisfied at a point in time upon the closing of a strategic transaction, completion of a financing or underwriting arrangement, or some other defined outcome (e.g., providing a fairness opinion). At this time, the Company has transferred control of the promised service and the customer obtains control. As these arrangements represent a single performance obligation, allocation of the transaction price is not necessary. The Company has elected to apply the following optional exemptions regarding disclosure of its remaining performance obligations: (i) the Company's performance obligation is part of a contract that has an original expected duration of one year or less and/or (ii) the variable consideration is allocated entirely to a wholly unsatisfied promise to transfer a distinct service that forms part of a single performance obligation. Institutional Brokerage Institutional brokerage revenues include (i) commissions received from customers for the execution of brokerage transactions in listed and over-the-counter ("OTC") equity, fixed income, convertible debt and derivative securities, which are recognized at a point in time on the trade date because the customer has obtained the rights to the underlying security provided by the trade execution service, (ii) trading gains and losses, recorded based on changes in the fair value of long and short security positions in the reporting period, and (iii) fees received by the Company for research services and corporate access offerings, which are primarily recognized at a point in time. The Company permits institutional customers to allocate a portion of their gross commissions to pay for research products and other services provided by third parties. The amounts allocated for those purposes are commonly referred to as commission share agreements or "soft dollar" arrangements. As the Company is not acting as a principal in satisfying the performance obligation for these arrangements, expenses relating to soft dollars are netted against commission revenues and included in other liabilities and accrued expenses on the consolidated statements of financial condition. Interest Income and Expense The Company nets interest expense within net revenues to mitigate the effects of fluctuations in interest rates on the Company's consolidated statements of operations. The Company recognizes contractual interest on financial instruments owned and financial instruments sold, but not yet purchased (excluding derivative instruments) on an accrual basis as a component of interest income and expense. The Company recognizes contractual interest on installment fee receivables on an accrual basis as interest income. The Company accounts for interest related to its financing arrangements on an accrual basis with related interest recorded as interest expense. Investment Income/(Loss) Investment income/(loss) includes realized and unrealized gains and losses from the Company's investments, as well as management and performance fees generated from the Company’s alternative asset management funds. The performance obligation related to the transfer of management and investment advisory services is satisfied over time and the related management fees are recognized under the output method, which reflects the fees that the Company has a right to invoice based on the services provided during the period. Fees are defined as a percentage of committed and/or invested capital. Amounts related to remaining performance obligations are not disclosed as the Company applies the output method. Performance fees, if earned, are recognized when it is probable that such revenue will not be reversed in a future period. Management will consider such factors as the remaining assets and residual life of the fund to conclude whether it is probable that a significant reversal of revenue will not occur in the future.
Stock-Based Compensation | Stock-Based Compensation FASB Accounting Standards Codification Topic 718, "Compensation – Stock Compensation," ("ASC 718") requires all stock-based compensation to be expensed on the consolidated statements of operations based on the grant date fair value of the award. Compensation expense related to stock-based awards that do not require future service are recognized in the year in which the awards were deemed to be earned. Stock-based awards that require future service are amortized over the relevant service period. Forfeitures of awards with service conditions are accounted for when they occur. See Note 18 for additional information on the Company's accounting for stock-based compensation.
Income Taxes | Income Taxes The Company files a consolidated U.S. federal income tax return, which includes all of its qualifying subsidiaries. The Company is also subject to income tax in various states and municipalities and those foreign jurisdictions in which it operates. Income taxes are provided for using the asset and liability method. Deferred tax assets and liabilities are recognized for the expected future tax consequences attributable to temporary differences between amounts reported for income tax purposes and financial statement purposes, using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The realization of deferred tax assets is assessed and a valuation allowance is recognized to the extent that it is more likely than not that any portion of a deferred tax asset will not be realized. Tax reserves for uncertain tax positions are recorded in accordance with FASB Accounting Standards Codification Topic 740, "Income Taxes" ("ASC 740").
Earnings Per Share | Earnings Per Share ("EPS") Basic earnings per common share is computed by dividing net income attributable to Piper Sandler Companies by the weighted average number of common shares outstanding for the period. Diluted earnings per common share is calculated by adjusting the weighted average outstanding shares to assume conversion of all potentially dilutive stock options, restricted stock units and restricted shares. The Company uses the treasury stock method to calculate diluted earnings per common share. See Note 22 for additional information on the Company's calculation of EPS.
Foreign Currency Translation | Foreign Currency Translation The Company consolidates foreign subsidiaries which have designated their local currency as their functional currency. Assets and liabilities of these foreign subsidiaries are translated at period-end rates of exchange. The gains or losses resulting from translating foreign currency financial statements are included in other comprehensive income/(loss). Gains or losses resulting from foreign currency transactions are included in net income.
