Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation of Interim Financial Information	Basis of Presentation of Interim Financial Information The accompanying unaudited condensed consolidated financial statements of Morningstar, Inc. and subsidiaries (Morningstar, we, our, the Company) have been prepared to conform to the rules and regulations of the Securities and Exchange Commission (SEC). The preparation of financial statements in conformity with accounting principles generally accepted in the United States (U.S. GAAP) requires management to make estimates and assumptions that affect the reported amount of assets, liabilities, revenues, and expenses. Actual results could differ from those estimates. In the opinion of management, the statements reflect all adjustments, which are of a normal recurring nature, necessary to present fairly our financial position, results of operations, equity, and cash flows. These financial statements and notes are unaudited and should be read in conjunction with our Audited Consolidated Financial Statements and Notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2020, filed with the SEC on February 26, 2021 (our Annual Report). The acronyms that appear in the Notes to our Unaudited Condensed Consolidated Financial Statements refer to the following: ASC: Accounting Standards Codification ASU: Accounting Standards Update FASB: Financial Accounting Standards Board COVID-19 Update We continue to closely monitor the impact of the COVID-19 pandemic on all aspects of our business and in the geographies in which we operate, including how it affects our team members, customers, suppliers, and the global markets. Since the situation surrounding the COVID-19 pandemic remains fluid with the emergence of new variants of the virus and vaccine distribution at various stages across geographies, we are actively managing our response and have assessed potential impacts to our financial position and operating results related to our consolidated financial statements for the three months ended March 31, 2021. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security (CARES) Act was signed into law intended to address the impact of the COVID-19 pandemic. On December 27, 2020, an additional stimulus was approved as part of the Consolidated Appropriations Act, 2021 (C AA). On March 11, 2021, the American Rescue Plan (ARP) Act was signed into law intended to provide additional economic relief to address the ongoing impact of COVID-19. We continue to monitor any effects that may result from these legislation or other similar legislation and governmental actions in geographies in which our business operates.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Our significant accounting policies are included in Note 2 of the Notes to our Audited Consolidated Financial Statements included in our Annual Report. Recently adopted accounting pronouncements Income Taxes: On December 18, 2019, the FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes (ASU No. 2019-12), which is intended to simplify the accounting for income taxes by removing certain exceptions to the general principles of ASC 740, Income Taxes, and providing for simplification in several other areas. The new standard became effective for us on January 1, 2021. The adoption of ASU No. 2019-12 did not have a material impact on our consolidated financial statements, related disclosures, or results of operations. Recently issued accounting pronouncements not yet adopted Reference Rate Reform : On March 12, 2020, the FASB issued ASU No. 2020-04: Facilitation of the Effects of Reference Rate Reform on Financial Reporting (Topic 848) (ASU No. 2020-04), which provides temporary optional expedients and exceptions for applying generally accepted accounting principles to contract modifications resulting from reference rate reform initiatives. The intention of the standard is to ease the potential accounting and financial reporting burden associated with transitioning away from the expiring London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative benchmark rates. The amendments in this update are applicable to contract modifications that replace a reference LIBOR rate beginning on March 12, 2020 through December 31, 2022. The optional expedients apply to our Credit Agreement and allow the Company to account for modifications due to reference rate reform by prospectively adjusting the effective interest rate on the Credit Agreement. As of March 31, 2021, we have not modified the Credit Agreement related to reference rate reform. We plan to apply the optional practical expedients and exceptions to modifications of the Credit Agreement affected by reference rate reform and are evaluating the effect on our consolidated financial statements, related disclosures, and results of operations.

(in millions) As of March 31, 2021 As of December 31, 2020 Term Facility, net of unamortized debt issuance costs of $0.1 million and $0.1 million, respectively $ 55.9 $ 100.8 2.32% Senior Notes due October 26, 2030, net of unamortized debt issuance costs of $1.7 million and $1.7 million, respectively 348.3 348.3 Long-term debt $ 404.2 $ 449.1 Credit Agreement In connection with the acquisition of Ratings Acquisition Corp (DBRS) on July 2, 2019, the Company entered into a senior credit agreement (the Credit Agreement). The Credit Agreement provides the Company with a five-year multi-currency credit facility with an initial borrowing capacity of up to $750.0 million, including a $300.0 million revolving credit facility (the Revolving Credit Facility) and a term loan facility of $450.0 million (the Term Facility). The Credit Agreement also provides for the issuance of up to $50.0 million of letters of credit and a $100.0 million sub-limit for a swingline facility under the Revolving Credit Facility. The Credit Agreement will expire on July 2, 2024. As of March 31, 2021, our total outstanding debt under the Credit Agreement was $55.9 million with borrowing availability of $300.0 million under the Revolving Credit Facility. The interest rate applicable to any loan under the Credit Agreement is, at our option, either: (i) the applicable LIBOR plus an applicable margin for such loans, which ranges between 1.00% and 1.50%, based on our consolidated leverage ratio or (ii) the lender's base rate plus the applicable margin for such loans, which ranges between 0.00% and 0.50%, based on our consolidated leverage ratio. The proceeds of the Term Facility and initial borrowings under the Revolving Credit Facility were used to finance the acquisition of DBRS. The proceeds of future borrowings under the Revolving Credit Facility may be used for working capital, capital expenditures or any other lawful corporate purpose. The portions of deferred debt issuance costs related to the Revolving Credit Facility are included in other current and other non-current assets, and the portion of deferred debt issuance costs related to the Term Facility is reported as a reduction to the carrying amount of the Term Facility. Amortization of debt issuance costs related to the Revolving Credit Facility are amortized on a straight-line basis to interest expense over the term of the Credit Agreement. Amortization of debt issuance costs related to the Term Facility are amortized to interest expense using the effective interest method over the term of the Credit Agreement. 364-Day Revolving Credit Facility On June 30, 2020, we entered into a 364-day revolving credit facility (364-Day Revolving Credit Facility) providing for borrowings in an aggregate principal amount of up to $50.0 million. The proceeds of such borrowings may be used for working capital, capital expenditures, and any other lawful corporate purpose. As of March 31, 2021, no borrowings were outstanding under the 364-Day Revolving Credit Facility. Private Placement Debt Offering On October 26, 2020, we completed the issuance and sale of $350.0 million aggregate principal amount of 2.32% senior notes due October 26, 2030 (the 2030 Notes), in a private placement exempt from the registration requirements of the Securities Act of 1933, as amended. Proceeds were primarily used to pay off a portion of the Company's outstanding debt under the Credit Agreement. Interest on the 2030 Notes will be paid semi-annually on each October 30 and April 30 during the term of the 2030 Notes and at maturity, with the first interest payment date occurring on April 30, 2021. As of March 31, 2021, our total outstanding debt (net of issuance costs) under the 2030 Notes was $348.3 million. Compliance with Covenants Each of the Credit Agreement, the 364-Day Revolving Credit Facility, and the 2030 Notes include customary representations, warranties, and covenants, including financial covenants, that require us to maintain specified ratios of consolidated earnings before interest, taxes, depreciation, and amortization (EBITDA) to consolidated interest charges and consolidated funded indebtedness to consolidated EB ITDA, which are tested on a quarterly basis. We were in compliance with these financial covenants as of March 31, 2021.

Revenue from Contract with Customer [Abstract]
Revenue	Revenue Disaggregation of Revenue The following table presents our revenue disaggregated by revenue type. Sales and usage-based taxes are excluded from revenue. Three months ended March 31, (in millions) 2021 2020 License-based $ 266.1 $ 216.0 Asset-based 61.4 57.2 Transaction-based 65.3 50.8 Consolidated revenue $ 392.8 $ 324.0 License-based performance obligations are generally satisfied over time as the customer has access to the product or service during the term of the subscription license and the level of service is consistent during the contract period. License-based agreements typically have a term of 1 to 3 years, and are accounted for as subscription services available to customers and not as a license under the accounting guidance. License-based revenue is generated from the sale of PitchBook, Morningstar Data, Morningstar Direct, Morningstar Advisor Workstation, Sustainalytics, and other simil ar product licenses. Asset-based performance obligations are satisfied over time as the customer receives continuous access to a service for the term of the agreement. Asset-based arrangements typically have a term of 1 to 3 years. Asset-based fees 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 and significant disruptions in the market are evaluated to determine whether estimates of earned asset-based fees need to be revised for the current quarter. The timing of client asset reporting and the structure of certain contracts can result in a one-quarter lag between market movements and the impact on earned revenue. An estimate of variable consideration is included in the initial transaction price only to the extent it is probable that a significant reversal in the amount of the revenue recognized will not occur. Estimates of asset-based fees are based on the most recently completed quarter and, as a result, it is unlikely a significant reversal of revenue would occur. Asset-based revenue is generated by Investment Management, Workplace Solutions, and Morningstar Indexes. Transaction-based performance obligations are satisfied when the product or service is completed or delivered. Transaction-based revenue is generated by DBRS Morningstar, Internet advertising, and Morningstar-sponsored conferences. DBRS Morningstar revenue includes revenue from surveillance services, which is recognized over time, as the customer has access to the service during the surveillance period. Contract liabilities Our contract liabilities represent deferred revenue. We record contract liabilities when cash payments are received or due in advance of our performance, including amounts which may be refundable. The contract liabilities balance as of March 31, 2021 had a net increase of $58.6 million, primarily driven by cash payments received or payable in advance of satisfying our performance obligations. We reco gnized $152.9 million of revenue in the three months ended March 31, 2021 that was included in the contract liabilities balance as of December 31, 2020. We expect to recognize revenue related to our contract liabilities for the remainder of 2021 and subsequent years as follows: (in millions) As of March 31, 2021 Remainder of 2021 (from April 1 through December 31) $ 530.4 2022 206.6 2023 72.5 2024 20.2 2025 8.4 Thereafter 34.1 Total $ 872.2 The aggregate amount of revenue we expect to recognize for the remainder of 2021 and subsequent years is higher than our contract liability balance of $398.9 million as of March 31, 2021. The difference represents the value of future obligations for signed contracts where we have not yet begun to satisfy the performance obligations or have partially satisfied performance obligations. The table above does not include variable consideration for unsatisfied performance obligations related to certain of our license-based, asset-based, and transaction-based contracts as of March 31, 2021. We are applying the optional exemption available under ASC Topic 606, as the variable consideration relates to these unsatisfied performance obligations being fulfilled as a series. The performance obligations related to these contracts are expected to be satisfied over the next 1 to 3 years as services are provided to the client. For license-based contracts, the consideration received for services performed is based on the number of future users, which is not known until the services are performed. The variable consideration for this revenue can be affected by the number of user licenses, which cannot be reasonably estimated. For asset-based contracts, the consideration received for services performed is based on future asset values, which are not known until the services are performed. The variable consideration for this revenue can be affected by changes in the underlying value of fund assets due to client redemptions, additional investments, or movements in the market. For transaction-based contracts for Internet advertising, the consideration received for services performed is based on the number of impressions, which is not known until the impressions are created. The variable consideration for this revenue can be affected by the timing and quantity of impressions in any given period and cannot be reasonably estimated. As of March 31, 2021, the table above also does not include revenue for unsatisfied performance obligations related to certain of our license-based and transaction-based contracts with durations of one year or less since we are applying the optional exemption under ASC Topic 606. For certain license-based contracts, the remaining performance obligation is expected to be less than one year based on the corresponding subscription terms or the existence of cancellation terms that may be exercised causing the contract term to be less than one year from March 31, 2021. For transaction-based contracts, such as new credit rating issuances and Morningstar-sponsored conferences, the related performance obligations are expected to be satisfied within the next 12 months. Contract Assets Our contract assets represent accounts receivable, less allowance for credit losses, and deferred commissions. The following table summarizes our contract assets balance: (in millions) As of March 31, 2021 As of December 31, 2020 Accounts receivable, less allowance for credit losses $ 229.1 $ 205.1 Deferred commissions 42.4 39.6 Total contract assets $ 271.5 $ 244.7

Segment Reporting [Abstract]
Segment and Geographical Area Information	Segment and Geographical Area 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 of the Audited Consolidated Financial Statements included in our Annual Report. We evaluate the performance of our reporting segment based on revenue and operating income.

Fair Value Disclosures [Abstract]
Investments and Fair Value Measurements	Fair Value Measurements As of March 31, 2021 and December 31, 2020, our investment balances totaled $50.1 million and $41.7 million, respectively. We classify our investments into three categories: available-for-sale, held-to-maturity, an d trading securities. 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. 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. Financial liabilities that are classified as Level 3 within the fair value hierarchy include contingent consideration liabilities o f $51.4 million th at reflect potential future payments that are contingent upon the achievement of certain revenue metrics related to our acquisition of Sustainalytics and will be paid on June 30, 2021 and June 30, 2022. This additional purchase consideration, which is contingent, is recognized at fair value at the date of acquisition using a Monte Carlo simulation, which requires the use of management assumptions and inputs, such as projected financial information related to revenue growth and expected margin percentage, among other valuation related items, and is remeasured each reporting period until the contingency is resolved with any changes in fair value recorded in current period earnings. At March 31, 2021, the fair value of the contingent consideration liability was impacted by foreign currency translations and not by adjustments to key assumptions used in our fair value estimates compared to the assumptions used in the acquisition date fair value estimates.

Leases [Abstract]
Leases	Leases We lease office space and certain equipment under various operating and finance leases, with most of our lease portfolio consisting of operating leases for office space. We determine whether an arrangement is, or includes, an embedded lease at contract inception. Operating lease assets and lease liabilities are recognized at the commencement date and initially measured using the present value of lease payments over the defined lease term. Lease expense is recognized on a straight-line basis over the lease term. For finance leases, we also recognize a finance lease asset and finance lease liability at inception, with lease expense recognized as interest expense and amortization. A contract is or contains an embedded lease if the contract meets all of the below criteria: • there is an identified asset; • we obtain substantially all the economic benefits of the asset; and • we have the right to direct the use of the asset. For initial measurement of the present value of lease payments and for subsequent measurement of lease modifications, we are required to use the rate implicit in the lease, if available. However, as most of our leases do not provide an implicit rate, we use our incremental borrowing rate, which is a collateralized rate. To apply the incremental borrowing rate, we used a portfolio approach and grouped leases based on similar lease terms in a manner whereby we reasonably expect that the application does not differ materially from a lease-by-lease approach. Our leases have remaining lease terms of approximately 1 year to 13 years, which may include the option to extend the lease when it is reasonably certain we will exercise that option. We do not have lease agreements with residual value guarantees, sale leaseback terms, or material restrictive covenants. Leases with an initial term of 12 months or less are not recognized on the balance sheet. We recognize lease expense for these leases on a straight-line basis over the lease term. The following table summarizes our operating lease assets and lease liabilities: Leases (in millions) Classification on the Balance Sheet As of March 31, 2021 As of December 31, 2020 Assets Operating Operating lease assets $ 138.9 $ 147.7 Liabilities Operating Operating lease liabilities, current $ 37.7 $ 39.9 Operating Operating lease liabilities, non-current 128.5 137.7 Total lease liabilities $ 166.2 $ 177.6 Our operating lease expense for the three months ended March 31, 2021 was $10.9 million, compared with $9.7 million for the three months ended March 31, 2020. Charges related to our operating leases that are variable and, therefore, not included in the measurement of the lease liabilities, were $4.4 million for the three months ended March 31, 2021, compared with $3.4 million for the three months ended March 31, 2020. We made lease payments of $12.3 million during the three months ended March 31, 2021, compared with $10.5 million during the three months ended March 31, 2020.

Income Taxes	Income Taxes Effective Tax Rate The following table shows our effective tax rate for the three months ended March 31, 2021 and 2020: Three months ended March 31, (in millions) 2021 2020 Income before income taxes and equity in net income (loss) of unconsolidated entities $ 67.3 $ 33.2 Equity in net income (loss) of unconsolidated entities 1.7 (0.8) Total $ 69.0 $ 32.4 Income tax expense $ 14.1 $ 8.5 Effective tax rate 20.4 % 26.2 % Our effective tax rate in the first quarter of 2021 was 20.4%, a decrease of 5.8 percentage points, compared with the same period in the prior year. The decrease is partially attributable to a reduction in our reserves for unrecognized tax benefits due to lapses of statutes of limitations. Also, our effective tax rate in the first quarter of 2020 was higher due to a non-deductible foreign exchange loss for which we did not record a tax benefit. Unrecognized Tax Benefits The table below provides information concerning our gross unrecognized tax benefits as of March 31, 2021 and December 31, 2020, as well as the effect these gross unrecognized tax benefits would have on our income tax expense, if they were recognized. (in millions) As of March 31, 2021 As of December 31, 2020 Gross unrecognized tax benefits $ 10.8 $ 11.8 Gross unrecognized tax benefits that would affect income tax expense $ 10.8 $ 11.8 Decrease in income tax expense upon recognition of gross unrecognized tax benefits $ 10.6 $ 11.6 Our Unaudited Condensed Consolidated Balance Sheets include the following liabilities for unrecognized tax benefits. These amounts include interest and penalties, less any associated tax benefits. Liabilities for Unrecognized Tax Benefits (in millions) As of March 31, 2021 As of December 31, 2020 Current liability $ 6.3 $ 7.6 Non-current liability 5.4 5.1 Total liability for unrecognized tax benefits $ 11.7 $ 12.7 Because we conduct business globally, we file income tax returns in U.S. federal, state, local, and foreign jurisdictions. We are currently under audit by federal, state, and local tax authorities in the U.S. as well as tax authorities in certain non-U.S. jurisdictions. It is likely that the examination phase of some of these federal, state, local, and non-U.S. audits will conclude in 2021. It is not possible to estimate the effect of current audits on previously recorded unrecognized tax benefits. Approximately 61% of our cash, cash equivalents, and investments balance as of March 31, 2021 was held by our operations outside of the United States. We generally consider our U.S. directly-owned foreign subsidiary earnings to be permanently reinvested. We believe that our cash balances and investments in the United States, along with cash generated from our U.S. operations, will be sufficient to meet our U.S. operating and cash needs for the foreseeable future, without requiring us to repatriate earnings from these foreign subsidiaries.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies We record accrued liabilities for litigation, regulatory, and other business matters when those matters represent loss contingencies that are both probable and estimable. In these cases, there may be an exposure to loss in excess of any amounts accrued. When a loss contingency is not both probable and estimable, we do not establish an accrued liability. As litigation, regulatory, or other business matters develop, we evaluate on an ongoing basis whether such matters present a loss contingency that is probable and estimable. Data Audits and Reviews In our global data business, we include in our products, or directly redistribute to our customers, data and information licensed from third-party vendors. Our compliance with the terms of these licenses is reviewed internally and is also subject to audit by the third-party vendors. At any given time, we may be undergoing several such internal reviews and third-party vendor audits and the results and findings may indicate that we may be required to make a payment for prior data usage. Due to a lack of available information and data, as well as potential variations of an y audit or internal review findings, we generally are not able to reasonably estimate a possible loss, or range of losses, for these matters. In situations where more information or specific areas subject to audit are available, we may be able to estimate a potential range of losses. While we cannot predict the outcome of these processes, we do not anticipate they will have a material adverse effect on our business, operating results, or financial position. Our financial results as of March 31, 2021 include an immaterial accrual related to certain in-progress audits and reviews. Credit Ratings Matters On February 16, 2021, the SEC filed a civil action in the United States District Court for the Southern District of New York against Morningstar Credit Ratings, LLC (MCR). MCR was formerly registered with the SEC as a Nationally Recognized Statistical Ratings Organization (NRSRO), but effective in December 2019, it withdrew its NRSRO registration. MCR no longer operates as a credit rating agency. The SEC’s complaint relates to MCR’s former commercial mortgage-backed securities ratings methodology during the period from 2015 to March 2017, and it alleges violations of certain filing and internal control requirements that applied to MCR when it was an NRSRO. On April 19, 2021, MCR filed a motion with the Court to dismiss the complaint. Our financial results as of March 31, 2021 include an immaterial accrual related to this matter. In April 2021, the staff of the Division of Enforcement of the SEC provided a Wells Notice to DBRS, Inc. (DBRS), indicating that the staff had made a preliminary determination to recommend that the Commission authorize an enforcement action in connection with five DBRS credit ratings on U.S. Collateralized Loan Obligation (CLO) combination notes that were assigned between 2016 and 2019. CLO combination notes are notes formed by packaging multiple components from a CLO transaction into a single rated note. The enforcement action would relate to the adequacy of DBRS’s policies and procedures with respect to its credit rating symbols, numbers and scores used in connection with these CLO combination notes. DBRS has not assigned a credit rating on a CLO combination note since 2019. At this time, only two DBRS credit ratings on CLO combination notes remain outstanding. DBRS intends to submit a written response to the Wells Notice. Given the current stage of this matter, we are not able to reasonably estimate a possible loss, range of losses, or other impact that may be associated with its outcome. At this time, we do not believe any outcome in either of these matters will have a material adverse effect on our business, operating results, or financial position. Other Matters We are involved from time to time in regulatory investigations and legal proceedings that arise in the normal course of our business. While it is difficult to predict the outcome of any particular investigation or proceeding, we do not believe the result of any of these matters will have a material adverse effect on our business, operating results, or financial position.

Recent Accounting Pronouncements Policy	Recently adopted accounting pronouncements Income Taxes: On December 18, 2019, the FASB issued ASU No. 2019-12, Simplifying the Accounting for Income Taxes (ASU No. 2019-12), which is intended to simplify the accounting for income taxes by removing certain exceptions to the general principles of ASC 740, Income Taxes, and providing for simplification in several other areas. The new standard became effective for us on January 1, 2021. The adoption of ASU No. 2019-12 did not have a material impact on our consolidated financial statements, related disclosures, or results of operations. Recently issued accounting pronouncements not yet adopted Reference Rate Reform : On March 12, 2020, the FASB issued ASU No. 2020-04: Facilitation of the Effects of Reference Rate Reform on Financial Reporting (Topic 848) (ASU No. 2020-04), which provides temporary optional expedients and exceptions for applying generally accepted accounting principles to contract modifications resulting from reference rate reform initiatives. The intention of the standard is to ease the potential accounting and financial reporting burden associated with transitioning away from the expiring London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative benchmark rates. The amendments in this update are applicable to contract modifications that replace a reference LIBOR rate beginning on March 12, 2020 through December 31, 2022. The optional expedients apply to our Credit Agreement and allow the Company to account for modifications due to reference rate reform by prospectively adjusting the effective interest rate on the Credit Agreement. As of March 31, 2021, we have not modified the Credit Agreement related to reference rate reform. We plan to apply the optional practical expedients and exceptions to modifications of the Credit Agreement affected by reference rate reform and are evaluating the effect on our consolidated financial statements, related disclosures, and results of operations.

Revenue	Revenue Disaggregation of Revenue The following table presents our revenue disaggregated by revenue type. Sales and usage-based taxes are excluded from revenue. Three months ended March 31, (in millions) 2021 2020 License-based $ 266.1 $ 216.0 Asset-based 61.4 57.2 Transaction-based 65.3 50.8 Consolidated revenue $ 392.8 $ 324.0 License-based performance obligations are generally satisfied over time as the customer has access to the product or service during the term of the subscription license and the level of service is consistent during the contract period. License-based agreements typically have a term of 1 to 3 years, and are accounted for as subscription services available to customers and not as a license under the accounting guidance. License-based revenue is generated from the sale of PitchBook, Morningstar Data, Morningstar Direct, Morningstar Advisor Workstation, Sustainalytics, and other simil ar product licenses. Asset-based performance obligations are satisfied over time as the customer receives continuous access to a service for the term of the agreement. Asset-based arrangements typically have a term of 1 to 3 years. Asset-based fees 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 and significant disruptions in the market are evaluated to determine whether estimates of earned asset-based fees need to be revised for the current quarter. The timing of client asset reporting and the structure of certain contracts can result in a one-quarter lag between market movements and the impact on earned revenue. An estimate of variable consideration is included in the initial transaction price only to the extent it is probable that a significant reversal in the amount of the revenue recognized will not occur. Estimates of asset-based fees are based on the most recently completed quarter and, as a result, it is unlikely a significant reversal of revenue would occur. Asset-based revenue is generated by Investment Management, Workplace Solutions, and Morningstar Indexes. Transaction-based performance obligations are satisfied when the product or service is completed or delivered. Transaction-based revenue is generated by DBRS Morningstar, Internet advertising, and Morningstar-sponsored conferences. DBRS Morningstar revenue includes revenue from surveillance services, which is recognized over time, as the customer has access to the service during the surveillance period. Contract liabilities Our contract liabilities represent deferred revenue. We record contract liabilities when cash payments are received or due in advance of our performance, including amounts which may be refundable. The contract liabilities balance as of March 31, 2021 had a net increase of $58.6 million, primarily driven by cash payments received or payable in advance of satisfying our performance obligations. We reco gnized $152.9 million of revenue in the three months ended March 31, 2021 that was included in the contract liabilities balance as of December 31, 2020. We expect to recognize revenue related to our contract liabilities for the remainder of 2021 and subsequent years as follows: (in millions) As of March 31, 2021 Remainder of 2021 (from April 1 through December 31) $ 530.4 2022 206.6 2023 72.5 2024 20.2 2025 8.4 Thereafter 34.1 Total $ 872.2 The aggregate amount of revenue we expect to recognize for the remainder of 2021 and subsequent years is higher than our contract liability balance of $398.9 million as of March 31, 2021. The difference represents the value of future obligations for signed contracts where we have not yet begun to satisfy the performance obligations or have partially satisfied performance obligations. The table above does not include variable consideration for unsatisfied performance obligations related to certain of our license-based, asset-based, and transaction-based contracts as of March 31, 2021. We are applying the optional exemption available under ASC Topic 606, as the variable consideration relates to these unsatisfied performance obligations being fulfilled as a series. The performance obligations related to these contracts are expected to be satisfied over the next 1 to 3 years as services are provided to the client. For license-based contracts, the consideration received for services performed is based on the number of future users, which is not known until the services are performed. The variable consideration for this revenue can be affected by the number of user licenses, which cannot be reasonably estimated. For asset-based contracts, the consideration received for services performed is based on future asset values, which are not known until the services are performed. The variable consideration for this revenue can be affected by changes in the underlying value of fund assets due to client redemptions, additional investments, or movements in the market. For transaction-based contracts for Internet advertising, the consideration received for services performed is based on the number of impressions, which is not known until the impressions are created. The variable consideration for this revenue can be affected by the timing and quantity of impressions in any given period and cannot be reasonably estimated. As of March 31, 2021, the table above also does not include revenue for unsatisfied performance obligations related to certain of our license-based and transaction-based contracts with durations of one year or less since we are applying the optional exemption under ASC Topic 606. For certain license-based contracts, the remaining performance obligation is expected to be less than one year based on the corresponding subscription terms or the existence of cancellation terms that may be exercised causing the contract term to be less than one year from March 31, 2021. For transaction-based contracts, such as new credit rating issuances and Morningstar-sponsored conferences, the related performance obligations are expected to be satisfied within the next 12 months. Contract Assets Our contract assets represent accounts receivable, less allowance for credit losses, and deferred commissions. The following table summarizes our contract assets balance: (in millions) As of March 31, 2021 As of December 31, 2020 Accounts receivable, less allowance for credit losses $ 229.1 $ 205.1 Deferred commissions 42.4 39.6 Total contract assets $ 271.5 $ 244.7
