Summary of Significant Accounting Policies (Policies)	12 Months Ended
Dec. 31, 2022
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation. We conduct our business operations through wholly- or majority-owned operating subsidiaries. The accompanying consolidated financial statements include the accounts of Morningstar, Inc. and our subsidiaries. We consolidate assets, liabilities, and results of operations of subsidiaries in which we have a controlling interest and eliminate all significant intercompany accounts and transactions. We account for investments in entities in which we exercise significant influence, but do not control, using the equity method. As part of our investment management operations, we manage certain funds outside of the U.S. that are considered variable interest entities. For most of these variable interest entities, we do not have a variable interest. In cases where we do have a variable interest, we are not the primary beneficiary. Accordingly, we do not consolidate any of these variable interest entities.
Use of Estimates	Use of Estimates. The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. (GAAP) requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses during the reporting period. Actual results may differ from these estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents. Cash and cash equivalents consist of cash and investments with original maturities of three months or less. We state them at cost, which approximates fair value. We state the portion of our cash equivalents that are invested in money market funds at fair value, as these funds are actively traded and have quoted market prices.
Investments	Investments. We account for our investments in debt securities in accordance with FASB ASC 320, Investments—Debt Securities (FASB ASC 320). We classify our debt securities into two categories: held-to-maturity and available-for-sale. •Held-to-maturity: We classify certain investments, primarily certificates of deposit, as held-to-maturity securities, based on our intent and ability to hold these securities to maturity. We record held-to-maturity investments at amortized cost in our Consolidated Balance Sheets. •Available-for-sale: Investments not considered held-to-maturity or trading securities are classified as available-for-sale securities. Available-for-sale securities primarily consist of marketable debt securities. We report unrealized gains and losses for available-for-sale securities as other comprehensive income (loss), net of related income taxes. We record these securities at their fair values in our Consolidated Balance Sheets. We account for our investments in equity securities in accordance with FASB ASC 321, Investments— Equity Securities (FASB ASC 321). We measure equity investments at fair value with the related realized and unrealized gains and losses recognized in our Consolidated Statements of Income. For equity investments without a readily determinable fair value, we measure these at cost less impairment and adjusting for observable price changes in orderly transactions. We will apply this measurement method to the investment until or if it becomes eligible to be measured at fair value, which is reassessed at each reporting period. We account for non-marketable equity investments over which we exercise significant influence, but do not have control over the investee, under the equity method.
Fair Value Measurements	Fair Value Measurements. FASB ASC 820, Fair Value Measurements (FASB ASC 820) defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. Under FASB ASC 820, fair value 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 as of the measurement date. The standard applies whenever other standards require (or permit) assets or liabilities to be measured at fair value. FASB ASC 820 uses a fair value hierarchy based on three broad levels of valuation inputs: • Level 1: Valuations based on quoted prices in active markets for identical assets or liabilities that we have the ability to access. • Level 2: Valuations based on quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly. • Level 3: Valuations based on inputs that are unobservable and significant to the overall fair value measurement. We provide additional information about our cash equivalents and investments that are subject to FASB ASC 820 in Note 7. We classify our investments into two categories: equity investments and debt securities. We further classify our debt securities into available-for-sale and held-to-maturity. Our investment portfolio consists of stocks, bonds, options, mutual funds, money market funds, or exchange-traded products that replicate the model portfolios and strategies created by Morningstar. These investment accounts may also include exchange-traded products where Morningstar is an index provider. Except for the convertible note described below, all investments in our investment portfolio have valuations based on quoted prices in active markets for identical assets or liabilities that we have the ability to access, and, therefore, are classified as Level 1 within the fair value hierarchy.
Business Combinations	Business Combinations. When we acquire a business, we account for the business combination in accordance with FASB ASC 805, Business Combinations (FASB ASC 805). We recognize and measure the fair value of the acquired business and allocate the purchase price to the identifiable tangible and intangible assets acquired and liabilities assumed based upon their estimated fair values at the date of acquisition. The difference between the purchase price and the estimated fair value of the net assets acquired or the excess of the aggregate estimated fair values of assets acquired and liabilities assumed is recorded as goodwill. In determining the estimated fair values of assets acquired and liabilities assumed in a business combination, we use various recognized valuation methods, including discounted cash flow, Monte Carlo simulations, and relief from royalty. For a business combination achieved in stages, we remeasure our previously held equity interest immediately before the acquisition to the acquisition date fair value and recognize any gain in our Consolidated Statements of Income. We recognize the fair value of any contingent payments at the date of acquisition as part of the consideration transferred to acquire a business. The liability associated with contingent consideration is remeasured to fair value at each reporting period subsequent to the date of acquisition considering factors that may impact the timing and amount of contingent payments until the term of the agreement has expired or the contingency is resolved. Any changes in the fair value measurement will be recorded in our Consolidated Statements of Income. In evaluating the characterization of contingent and deferred payments, we analyze relevant factors, including the nature of the payment, continuing employment requirements, incremental payments to employees of the acquired business, and timing and rationale underlying the transaction, to determine whether the payments should be accounted for as additional purchase consideration or post-combination related services. We expense direct costs related to the business combination, such as accounting, legal, valuation, and other professional fees, as incurred. We recognize restructuring costs, including severance and relocation for employees of the acquired entity, as post-combination expenses unless the target entity meets the criteria of ASC 420, Exit or Disposal Cost Obligations, on the acquisition date. As part of the purchase price allocation, we follow the requirements of FASB ASC 740, Income Taxes (FASB ASC 740). This includes establishing deferred tax assets or liabilities reflecting the difference between the values assigned for financial statement purposes and income tax purposes. In certain acquisitions, the goodwill resulting from the purchase price allocation may not be deductible for income tax purposes. FASB ASC 740 prohibits recognition of a deferred tax asset or liability for temporary differences in goodwill if goodwill is not amortizable and deductible for tax purposes.
Goodwill	Goodwill. Changes in the carrying amount of our recorded goodwill are mainly the result of business acquisitions, divestitures, and the effect of foreign currency translations. In accordance with FASB ASC 350, Intangibles—Goodwill and Other, we do not amortize goodwill; instead, goodwill is subject to an impairment test annually, or whenever indicators of impairment exist. An impairment would occur if the carrying amount of a reporting unit exceeded the fair value of that reporting unit. We performed our annual impairment review in the fourth quarter and did not record any impairment losses in 2022, 2021, and 2020.
Intangible Assets	Intangible Assets. We amortize intangible assets using the straight-line method over their estimated useful lives, which range from one to twenty years. We have no intangible assets with indefinite useful lives. In accordance with FASB ASC 360-10-35, Subsequent Measurement—Impairment or Disposal of Long-Lived Assets, we review intangible assets for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. If the value of future undiscounted cash flows is less than the carrying amount of an asset group, we record an impairment loss based on the excess of the carrying amount over the fair value of the asset group. We did not record any impairment losses in 2022, 2021, and 2020.
Property, Equipment, and Depreciation	Property, Equipment, and Depreciation. We state property and equipment at historical cost, net of accumulated depreciation in accordance with FASB ASC 360-10, Property, Plant, and Equipment. We depreciate property and equipment using the straight-line method based on the useful life of the asset, which ranges from three to seven years. We amortize leasehold improvements over the lease term or their useful lives, whichever is shorter. Long-lived assets that are held and used are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. If the value of future undiscounted cash flows is less than the carrying amount of an asset group, we record an impairment loss based on the excess of the carrying amount over the fair value of the asset group.
Computer Software and Internal Product Development Costs	Computer Software and Internal Product Development Costs. We capitalize certain costs in accordance with FASB ASC 350-40, Internal-Use Software. Internal product development costs mainly consist of employee costs for developing new web-based products and certain major enhancements of existing products. We amortize these costs on a straight-line basis over the estimated economic life, which is generally three years. We include capitalized software development costs related to projects that have not been placed into service in our construction in progress balance.
Lesses	Leases. We account for our right-of-use assets and operating lease liabilities in accordance with FASB ASC 842, Leases (FASB ASC 842). We determine if a contract is or contains a lease at the inception of the contract. For identified operating leases, we recognize a lease liability and right-of-use asset on the consolidated balance sheet. The right-of-use asset represents our right to use an underlying asset for the lease term, and the operating lease liability represents the company's obligation to make lease payments. Our lease agreements consist primarily of real estate leases for office space and non-real estate leases for office equipment. In cases where an agreement contains both a lease and non-lease component, we do not allocate consideration to both components, but account for each as a single lease component by class of underlying asset. There are few instances of short-term agreements in our lease portfolio, which are typically arranged as needed and paid on a month-to-month basis. These leases are not recognized on the Consolidated Balance Sheet, but monthly lease expense is recognized on the Consolidated Statements of Income. Right-of-use assets and operating lease liabilities are measured using the present value of future lease payments of the lease term at the commencement date. Right-of-use assets also include initial direct costs incurred by the company, net of prepayments and lease incentives. In the absence of an explicit rate in the lease agreement, the discount rate used to calculate present value is equal to the company's incremental borrowing rate. Operating lease expense is recognized on a straight-line basis over the life of the lease and is included in general and administrative expenses on the Consolidated Statements of Income.
Revenue from Contract with Customer	Revenue Recognition. We recognize revenue in accordance with FASB ASC Topic 606, Revenue from Contracts with Customers (FASB ASC Topic 606). Under FASB ASC Topic 606, we recognize revenue by applying the following five-step model to each of our customer arrangements: 1.Identify the customer contract; 2.Identify the performance obligations in the contract; 3.Determine the transaction price; 4.Allocate the transaction price to the performance obligations; and 5.Recognize revenue when (or as) performance obligations are satisfied. Revenues are recognized when (or as) performance obligations are satisfied by transferring a promised product or service to the customer. Products or services are transferred when (or as) the customer obtains control of the product or service. The transaction price for a customer arrangement is the amount we expect to be entitled to in exchange for transferring the promised product or service. The transaction price may include fixed amounts, variable amounts, or both. When the right to payment exceeds revenue recognized, the result is an increase to deferred revenue. When a customer’s license-based contract is signed, the customer’s service is activated immediately, except where customizations are required. License-based arrangements, our largest source of revenue from customers, generally are billed quarterly or annually. Customers are typically given payment terms of zero to sixty days. Revenue from contracts with customers is derived from license-based arrangements, asset-based arrangements, and transaction-based arrangements. License-based revenue, which represents subscription services available to customers and not a license under the accounting guidance, is generated through subscription contracts with our customers of PitchBook, Morningstar Data, Morningstar Direct, Morningstar Sustainalytics, Morningstar Advisor Workstation, Morningstar Enterprise Components, and other similar products. Our performance obligations under these contracts are typically satisfied over time, as the customer has access to the service during the term of the subscription license and the level of service is consistent during the contract period. Each individual day within the contract period is viewed to be a service and the entirety of the service subscription term is determined to be a series combined into a single performance obligation and recognized over-time and on a straight-line basis, typically over terms of 1 to 3 years. Asset-based revenue is generated through contracts with our customers of Morningstar Investment Management, Workplace Solutions, and Morningstar Indexes. Our performance obligations under these contracts are a daily asset management performance obligation, which is determined to be a daily service and thus satisfied over time as the customer receives continuous access to a service for the contract term. We recognize revenue daily over the contract term based on the value of assets under management and a tiered fee agreed to with the customer. Asset-based arrangements typically have a term of 1 to 3 years. The fees from such arrangements represent variable consideration, and the customer does not make separate purchasing decisions that result in additional performance obligations. Significant changes in the underlying fund assets, or significant disruptions in the market, are evaluated to determine if revisions to estimates of earned asset-based fees for the current quarter are needed. An estimate of the average daily portfolio balance is a key input in determining revenue for a given period. Estimates are based on the most recently reported quarter, and, as a result, it is unlikely a significant reversal of revenue would occur. Transaction-based revenue is generated through contracts with our customers for DBRS Morningstar products and services, Internet advertising on Morningstar.com, and Morningstar-sponsored conferences. Our performance obligations for DBRS Morningstar include the issuance of the rating and may include surveillance services for a period of time as agreed with the customer. We allocate the transaction price to the deliverables based on their relative selling price, which is generally determined by the price we charge when the same deliverable is sold separately. Our performance obligation for the issuance of the rating is satisfied when the rating is issued, which is when we recognize the related revenue. Our performance obligations for surveillance services are satisfied over time, as the customer has access to the service during the surveillance period and the level of service is consistent during the contract period. Therefore, we recognize revenue for this performance obligation on a straight-line basis. Our performance obligations for Internet advertising and Morningstar-sponsored conferences are satisfied as the service is delivered; therefore, we recognize revenue when the performance obligation is satisfied (as the customer’s advertisements are displayed and at the completion of the Morningstar-sponsored conference). Our contracts with customers may include multiple performance obligations. For most of these arrangements, we generally allocate revenue to each performance obligation based on its estimated standalone selling price. We generally determine standalone selling prices based on prices charged to customers when the same performance obligation is sold separately. Our contracts with customers may include third-party involvement in providing goods or services to the customer. The inclusion of third-party content does not result in separate performance obligations because is it not delivered separately from the other service offerings. In these arrangements, the customer has contracted to receive a single, integrated and bundled solution with third-party and Morningstar content delivered via Morningstar’s subscription services. Revenue and related costs of revenue from third-party content is presented on a gross basis within the consolidated financial statements. Deferred revenue represents the portion of licenses or subscriptions billed or collected in advance of the service being provided which we expect to recognize as revenue in future periods.
Sales Commissions	Sales Commissions. We capitalize sales commissions, which are considered directly attributable to obtaining a customer contract under FASB ASC Topic 606 and FASB ASC 340-40, Other Assets and Deferred Costs - Contracts with Customers. Estimates of these capitalized costs are developed by using a portfolio approach that aggregates these costs by legal entity within their geographical regions. Capitalized sales commissions are amortized using the straight-line method over a period that is consistent with the transfer of the products or services to the customer to which the sales commission relates. The period of transfer for each portfolio is the shorter of the weighted-average customer life, or the economic life of the underlying technology that delivers the products or services. As of December 31, 2022, the period of transfer was determined to be approximately three years. Discretionary amounts which are added to sales commission payments are expensed as incurred, as they are not considered to be directly attributable to obtaining a customer contract.
Stock-Based Compensation Expense	Stock-Based Compensation Expense. We account for our stock-based compensation expense in accordance with FASB ASC 718, Compensation—Stock Compensation (FASB ASC 718). Our stock-based compensation expense reflects grants of restricted stock units, performance share awards, and market stock units. We measure the fair value of our restricted stock units and performance share awards on the grant date based on the closing market price of Morningstar's common stock on the day prior to the grant. For market stock units, we estimate the fair value of the awards using a Monte Carlo valuation model. We amortize the fair values to stock-based compensation expense, net of estimated forfeitures, ratably over the vesting period.We estimate expected forfeitures of all employee stock-based awards and recognize compensation cost only for those awards expected to vest. We determine forfeiture rates based on historical experience and adjust the estimated forfeitures to actual forfeiture experience, as needed.
Income Taxes	Income Taxes. We record deferred income taxes for the temporary differences between the carrying amount of assets and liabilities for financial statement purposes and tax purposes in accordance with FASB ASC 740, which prescribes the minimum recognition threshold a tax position is required to meet before being recognized in the financial statements. It also provides guidance on derecognition, measurement, classification, interest and penalties, accounting in interim periods, and disclosure for uncertain tax positions. We recognize interest and penalties related to unrecognized tax benefits as part of income tax expense in our Consolidated Statements of Income. We classify liabilities related to unrecognized tax benefits as either current or long-term liabilities in our Consolidated Balance Sheet, depending on when we expect to make payment.
Segment Information	Segment Information We report our results in a single reportable segment, which reflects how our chief operating decision maker allocates resources and evaluates our financial results. Because we have a single reportable segment, all required financial segment information can be found directly in the Consolidated Financial Statements. The accounting policies for our reportable segment are the same as those described in Note 2. We evaluate the performance of our reporting segment based on revenue and operating income.
Severance Costs	Severance: We account for post-employment benefits in accordance with FASB ASC 712, Compensation - Non-retirement Post-employment Benefits (FASB ASC 712). Under FASB ASC 712, we recognize compensation expense associated with these benefits as a liability when probable and estimable. In July 2022, the company began to significantly reduce its operations in Shenzhen, China and to shift the work related to its global business functions, including global product and software development, managed investment data collection and analysis, and equity data collection and analysis, to other Morningstar locations. As a result of these activities, the company incurred $25.9 million of severance expense in 2022, which represents substantially all of the severance costs expected to be incurred with the remainder to be recognized through the third quarter of 2023. These amounts were recorded within "General and administrative" on our Consolidated Statements of Income.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2022

Principles of Consolidation. We conduct our business operations through wholly- or majority-owned operating subsidiaries. The accompanying consolidated financial statements include the accounts of Morningstar, Inc. and our subsidiaries. We consolidate assets, liabilities, and results of operations of subsidiaries in which we have a controlling interest and eliminate all significant intercompany accounts and transactions.

We account for investments in entities in which we exercise significant influence, but do not control, using the equity method.

As part of our investment management operations, we manage certain funds outside of the U.S. that are considered variable interest entities. For most of these variable interest entities, we do not have a variable interest. In cases where we do have a variable interest, we are not the primary beneficiary. Accordingly, we do not consolidate any of these variable interest entities.

Use of Estimates

Use of Estimates. The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. (GAAP) requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses during the reporting period. Actual results may differ from these estimates.

Cash and Cash Equivalents

Cash and Cash Equivalents. Cash and cash equivalents consist of cash and investments with original maturities of three months or less. We state them at cost, which approximates fair value. We state the portion of our cash equivalents that are invested in money market funds at fair value, as these funds are actively traded and have quoted market prices.

Investments

Investments. We account for our investments in debt securities in accordance with FASB ASC 320, Investments—Debt Securities (FASB ASC 320). We classify our debt securities into two categories: held-to-maturity and available-for-sale.

•Held-to-maturity: We classify certain investments, primarily certificates of deposit, as held-to-maturity securities, based on our intent and ability to hold these securities to maturity. We record held-to-maturity investments at amortized cost in our Consolidated Balance Sheets.

•Available-for-sale: Investments not considered held-to-maturity or trading securities are classified as available-for-sale securities. Available-for-sale securities primarily consist of marketable debt securities. We report unrealized gains and losses for available-for-sale securities as other comprehensive income (loss), net of related income taxes. We record these securities at their fair values in our Consolidated Balance Sheets.

We account for our investments in equity securities in accordance with FASB ASC 321, Investments— Equity Securities (FASB ASC 321). We measure equity investments at fair value with the related realized and unrealized gains and losses recognized in our Consolidated Statements of Income. For equity investments without a readily determinable fair value, we measure these at cost less impairment and adjusting for observable price changes in orderly transactions. We will apply this measurement method to the investment until or if it becomes eligible to be measured at fair value, which is reassessed at each reporting period. We account for non-marketable equity investments over which we exercise significant influence, but do not have control over the investee, under the equity method.

Fair Value Measurements

Fair Value Measurements. FASB ASC 820, Fair Value Measurements (FASB ASC 820) defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. Under FASB ASC 820, fair value 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 as of the measurement date. The standard applies whenever other standards require (or permit) assets or liabilities to be measured at fair value.

FASB ASC 820 uses a fair value hierarchy based on three broad levels of valuation inputs:

• Level 1: Valuations based on quoted prices in active markets for identical assets or liabilities that we have the ability to access.

• Level 2: Valuations based on quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly.

• Level 3: Valuations based on inputs that are unobservable and significant to the overall fair value measurement.

We provide additional information about our cash equivalents and investments that are subject to FASB ASC 820 in Note 7.

We classify our investments into two categories: equity investments and debt securities. We further classify our debt securities into available-for-sale and held-to-maturity. Our investment portfolio consists of stocks, bonds, options, mutual funds, money market funds, or exchange-traded products that replicate the model portfolios and strategies created by Morningstar. These investment accounts may also include exchange-traded products where Morningstar is an index provider. Except for the convertible note described below, all investments in our investment portfolio have valuations based on quoted prices in active markets for identical assets or liabilities that we have the ability to access, and, therefore, are classified as Level 1 within the fair value hierarchy.

Business Combinations

Business Combinations. When we acquire a business, we account for the business combination in accordance with FASB ASC 805, Business Combinations (FASB ASC 805). We recognize and measure the fair value of the acquired business and allocate the purchase price to the identifiable tangible and intangible assets acquired and liabilities assumed based upon their estimated fair values at the date of acquisition. The difference between the purchase price and the estimated fair value of the net assets acquired or the excess of the aggregate estimated fair values of assets acquired and liabilities assumed is recorded as goodwill. In determining the estimated fair values of assets acquired and liabilities assumed in a business combination, we use various recognized valuation methods, including discounted cash flow, Monte Carlo simulations, and relief from royalty. For a business combination achieved in stages, we remeasure our previously held equity interest immediately before the acquisition to the acquisition date fair value and recognize any gain in our Consolidated Statements of Income.

We recognize the fair value of any contingent payments at the date of acquisition as part of the consideration transferred to acquire a business. The liability associated with contingent consideration is remeasured to fair value at each reporting period subsequent to the date of acquisition considering factors that may impact the timing and amount of contingent payments until the term of the agreement has expired or the contingency is resolved. Any changes in the fair value measurement will be recorded in our Consolidated Statements of Income. In evaluating the characterization of contingent and deferred payments, we analyze relevant factors, including the nature of the payment, continuing employment requirements, incremental payments to employees of the acquired business, and timing and rationale underlying the transaction, to determine whether the payments should be accounted for as additional purchase consideration or post-combination related services.

We expense direct costs related to the business combination, such as accounting, legal, valuation, and other professional fees, as incurred. We recognize restructuring costs, including severance and relocation for employees of the acquired entity, as post-combination expenses unless the target entity meets the criteria of ASC 420, Exit or Disposal Cost Obligations, on the acquisition date.

As part of the purchase price allocation, we follow the requirements of FASB ASC 740, Income Taxes (FASB ASC 740). This includes establishing deferred tax assets or liabilities reflecting the difference between the values assigned for financial statement purposes and income tax purposes. In certain acquisitions, the goodwill resulting from the purchase price allocation may not be deductible for income tax purposes. FASB ASC 740 prohibits recognition of a deferred tax asset or liability for temporary differences in goodwill if goodwill is not amortizable and deductible for tax purposes.

Goodwill

Goodwill. Changes in the carrying amount of our recorded goodwill are mainly the result of business acquisitions, divestitures, and the effect of foreign currency translations. In accordance with FASB ASC 350, Intangibles—Goodwill and Other, we do not amortize goodwill; instead, goodwill is subject to an impairment test annually, or whenever indicators of impairment exist. An impairment would occur if the carrying amount of a reporting unit exceeded the fair value of that reporting unit. We performed our annual impairment review in the fourth quarter and did not record any impairment losses in 2022, 2021, and 2020.

Intangible Assets

Intangible Assets. We amortize intangible assets using the straight-line method over their estimated useful lives, which range from one to twenty years. We have no intangible assets with indefinite useful lives. In accordance with FASB ASC 360-10-35, Subsequent Measurement—Impairment or Disposal of Long-Lived Assets, we review intangible assets for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. If the value of future undiscounted cash flows is less than the carrying amount of an asset group, we record an impairment loss based on the excess of the carrying amount over the fair value of the asset group. We did not record any impairment losses in 2022, 2021, and 2020.

Property, Equipment, and Depreciation

Property, Equipment, and Depreciation. We state property and equipment at historical cost, net of accumulated depreciation in accordance with FASB ASC 360-10, Property, Plant, and Equipment. We depreciate property and equipment using the straight-line method based on the useful life of the asset, which ranges from three to seven years. We amortize leasehold improvements over the lease term or their useful lives, whichever is shorter. Long-lived assets that are held and used are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. If the value of future undiscounted cash flows is less than the carrying amount of an asset group, we record an impairment loss based on the excess of the carrying amount over the fair value of the asset group.

Computer Software and Internal Product Development Costs

Computer Software and Internal Product Development Costs. We capitalize certain costs in accordance with FASB ASC 350-40, Internal-Use Software. Internal product development costs mainly consist of employee costs for developing new web-based products and certain major enhancements of existing products. We amortize these costs on a straight-line basis over the estimated economic life, which is generally three years. We include capitalized software development costs related to projects that have not been placed into service in our construction in progress balance.

Lesses

Leases. We account for our right-of-use assets and operating lease liabilities in accordance with FASB ASC 842, Leases (FASB ASC 842). We determine if a contract is or contains a lease at the inception of the contract. For identified operating leases, we recognize a lease liability and right-of-use asset on the consolidated balance sheet. The right-of-use asset represents our right to use an underlying asset for the lease term, and the operating lease liability represents the company's obligation to make lease payments.

Our lease agreements consist primarily of real estate leases for office space and non-real estate leases for office equipment. In cases where an agreement contains both a lease and non-lease component, we do not allocate consideration to both components, but account for each as a single lease component by class of underlying asset. There are few instances of short-term agreements in our lease portfolio, which are typically arranged as needed and paid on a month-to-month basis. These leases are not recognized on the Consolidated Balance Sheet, but monthly lease expense is recognized on the Consolidated Statements of Income.

Right-of-use assets and operating lease liabilities are measured using the present value of future lease payments of the lease term at the commencement date. Right-of-use assets also include initial direct costs incurred by the company, net of prepayments and lease incentives. In the absence of an explicit rate in the lease agreement, the discount rate used to calculate present value is equal to the company's incremental borrowing rate. Operating lease expense is recognized on a straight-line basis over the life of the lease and is included in general and administrative expenses on the Consolidated Statements of Income.

Revenue from Contract with Customer

Revenue Recognition. We recognize revenue in accordance with FASB ASC Topic 606, Revenue from Contracts with Customers (FASB ASC Topic 606).

Under FASB ASC Topic 606, we recognize revenue by applying the following five-step model to each of our customer arrangements:

1.Identify the customer contract;

2.Identify the performance obligations in the contract;

3.Determine the transaction price;

4.Allocate the transaction price to the performance obligations; and

5.Recognize revenue when (or as) performance obligations are satisfied.

Revenues are recognized when (or as) performance obligations are satisfied by transferring a promised product or service to the customer. Products or services are transferred when (or as) the customer obtains control of the product or service. The transaction price for a customer arrangement is the amount we expect to be entitled to in exchange for transferring the promised product or service. The transaction price may include fixed amounts, variable amounts, or both. When the right to payment exceeds revenue recognized, the result is an increase to deferred revenue. When a customer’s license-based contract is signed, the customer’s service is activated immediately, except where customizations are required. License-based arrangements, our largest source of revenue from customers, generally are billed quarterly or annually. Customers are typically given payment terms of zero to sixty days.

Revenue from contracts with customers is derived from license-based arrangements, asset-based arrangements, and transaction-based arrangements.

License-based revenue, which represents subscription services available to customers and not a license under the accounting guidance, is generated through subscription contracts with our customers of PitchBook, Morningstar Data, Morningstar Direct, Morningstar Sustainalytics, Morningstar Advisor Workstation, Morningstar Enterprise Components, and other similar products. Our performance obligations under these contracts are typically satisfied over time, as the customer has access to the service during the term of the subscription license and the level of service is consistent during the contract period. Each individual day within the contract period is viewed to be a service and the entirety of the service subscription term is determined to be a series combined into a single performance obligation and recognized over-time and on a straight-line basis, typically over terms of 1 to 3 years.

Asset-based revenue is generated through contracts with our customers of Morningstar Investment Management, Workplace Solutions, and Morningstar Indexes. Our performance obligations under these contracts are a daily asset management performance obligation, which is determined to be a daily service and thus satisfied over time as the customer receives continuous access to a service for the contract term. We recognize revenue daily over the contract term based on the value of assets under management and a tiered fee agreed to with the customer. Asset-based arrangements typically have a term of 1 to 3 years. The fees from such arrangements represent variable consideration, and the customer does not make separate purchasing decisions that result in additional performance obligations. Significant changes in the underlying fund assets, or significant disruptions in the market, are evaluated to determine if revisions to estimates of earned asset-based fees for the current quarter are needed. An estimate of the average daily portfolio balance is a key input in determining revenue for a given period. Estimates are based on the most recently reported quarter, and, as a result, it is unlikely a significant reversal of revenue would occur.

Transaction-based revenue is generated through contracts with our customers for DBRS Morningstar products and services, Internet advertising on Morningstar.com, and Morningstar-sponsored conferences. Our performance obligations for DBRS Morningstar include the issuance of the rating and may include surveillance services for a period of time as agreed with the customer. We allocate the transaction price to the deliverables based on their relative selling price, which is generally determined by the price we charge when the same deliverable is sold separately. Our performance obligation for the issuance of the rating is satisfied when the rating is issued, which is when we recognize the related revenue. Our performance obligations for surveillance services are satisfied over time, as the customer has access to the service during the surveillance period and the level of service is consistent during the contract period. Therefore, we recognize revenue for this performance obligation on a straight-line basis. Our performance obligations for Internet advertising and Morningstar-sponsored conferences are satisfied as the service is delivered; therefore, we recognize revenue when the performance obligation is satisfied (as the customer’s advertisements are displayed and at the completion of the Morningstar-sponsored conference).

Our contracts with customers may include multiple performance obligations. For most of these arrangements, we generally allocate revenue to each performance obligation based on its estimated standalone selling price. We generally determine standalone selling prices based on prices charged to customers when the same performance obligation is sold separately.

Our contracts with customers may include third-party involvement in providing goods or services to the customer. The inclusion of third-party content does not result in separate performance obligations because is it not delivered separately from the other service offerings. In these arrangements, the customer has contracted to receive a single, integrated and bundled solution with third-party and Morningstar content delivered via Morningstar’s subscription services. Revenue and related costs of revenue from third-party content is presented on a gross basis within the consolidated financial statements.

Deferred revenue represents the portion of licenses or subscriptions billed or collected in advance of the service being provided which we expect to recognize as revenue in future periods.

Sales Commissions

Sales Commissions. We capitalize sales commissions, which are considered directly attributable to obtaining a customer contract under FASB ASC Topic 606 and FASB ASC 340-40, Other Assets and Deferred Costs - Contracts with Customers. Estimates of these capitalized costs are developed by using a portfolio approach that aggregates these costs by legal entity within their geographical regions. Capitalized sales commissions are amortized using the straight-line method over a period that is consistent with the transfer of the products or services to the customer to which the sales commission relates. The period of transfer for each portfolio is the shorter of the weighted-average customer life, or the economic life of the underlying technology that delivers the products or services. As of December 31, 2022, the period of transfer was determined to be approximately three years. Discretionary amounts which are added to sales commission payments are expensed as incurred, as they are not considered to be directly attributable to obtaining a customer contract.

Stock-Based Compensation Expense

Stock-Based Compensation Expense. We account for our stock-based compensation expense in accordance with FASB ASC 718, Compensation—Stock Compensation (FASB ASC 718). Our stock-based compensation expense reflects grants of restricted stock units, performance share awards, and market stock units. We measure the fair value of our restricted stock units and performance share awards on the grant date based on the closing market price of Morningstar's common stock on the day prior to the grant. For market stock units, we estimate the fair value of the awards using a Monte Carlo valuation model. We amortize the fair values to stock-based compensation expense, net of estimated forfeitures, ratably over the vesting period.We estimate expected forfeitures of all employee stock-based awards and recognize compensation cost only for those awards expected to vest. We determine forfeiture rates based on historical experience and adjust the estimated forfeitures to actual forfeiture experience, as needed.

Income Taxes

Income Taxes. We record deferred income taxes for the temporary differences between the carrying amount of assets and liabilities for financial statement purposes and tax purposes in accordance with FASB ASC 740, which prescribes the minimum recognition threshold a tax position is required to meet before being recognized in the financial statements. It also provides guidance on derecognition, measurement, classification, interest and penalties, accounting in interim periods, and disclosure for uncertain tax positions.

We recognize interest and penalties related to unrecognized tax benefits as part of income tax expense in our Consolidated Statements of Income. We classify liabilities related to unrecognized tax benefits as either current or long-term liabilities in our Consolidated Balance Sheet, depending on when we expect to make payment.

Segment Information

Segment Information We report our results in a single reportable segment, which reflects how our chief operating decision maker allocates resources and evaluates our financial results. Because we have a single reportable segment, all required financial segment information can be found directly in the Consolidated Financial Statements. The accounting policies for our reportable segment are the same as those described in Note 2. We evaluate the performance of our reporting segment based on revenue and operating income.

Severance Costs

Severance: We account for post-employment benefits in accordance with FASB ASC 712, Compensation - Non-retirement Post-employment Benefits (FASB ASC 712). Under FASB ASC 712, we recognize compensation expense associated with these benefits as a liability when probable and estimable.

In July 2022, the company began to significantly reduce its operations in Shenzhen, China and to shift the work related to its global business functions, including global product and software development, managed investment data collection and analysis, and equity data collection and analysis, to other Morningstar locations.

As a result of these activities, the company incurred $25.9 million of severance expense in 2022, which represents substantially all of the severance costs expected to be incurred with the remainder to be recognized through the third quarter of 2023. These amounts were recorded within "General and administrative" on our Consolidated Statements of Income.
