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. License-based arrangements, our largest source of revenue from customers, generally is billed for the entire term, or billed annually (if the contract term is longer than one year). Customers are typically given payment terms of thirty to </span><span style="font-family:Arial;font-size:10pt;"><span>sixty days</span></span><span style="font-family:Arial;font-size:10pt;">, although some customers pay immediately.</span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Revenue from contracts with customers is derived from license-based arrangements, asset-based arrangements, and transaction-based arrangements.</span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">License-based revenue, which represents subscription services available to customers and not a license under the accounting guidance, is generated through subscription contracts entered into with our customers of Morningstar Data, Morningstar Direct, Morningstar Advisor Workstation, Morningstar Enterprise Components, PitchBook Data, 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 </span><span style="font-family:Arial;font-size:10pt;"><span>12</span></span><span style="font-family:Arial;font-size:10pt;"> to </span><span style="font-family:Arial;font-size:10pt;"><span>36 months</span></span><span style="font-family:Arial;font-size:10pt;">.</span></div><div style="line-height:120%;text-align:left;padding-left:22px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Asset-based revenue is generated through consulting service 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 (typically in a range of </span><span style="font-family:Arial;font-size:10pt;"><span>30</span></span><span style="font-family:Arial;font-size:10pt;">-</span><span style="font-family:Arial;font-size:10pt;"><span>55</span></span><span style="font-family:Arial;font-size:10pt;"> basis points of the customer’s average daily portfolio balance). Asset-based arrangements typically have a term of </span><span style="font-family:Arial;font-size:10pt;"><span>12</span></span><span style="font-family:Arial;font-size:10pt;"> to </span><span style="font-family:Arial;font-size:10pt;"><span>36 months</span></span><span style="font-family:Arial;font-size:10pt;">. 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 on estimates of earned asset-based fees for the current quarter are needed. An estimate of the average daily portfolio balance is included 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. </span></div><div style="line-height:120%;text-align:left;padding-left:22px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;background-color:#ffffff;">Transaction-based revenue is generated through contracts with our customers for the provision of DBRS Morningstar credit ratings, Internet advertising on morningstar.com, and Morningstar conferences.</span><span style="font-family:Arial;font-size:10pt;"> </span><span style="font-family:Arial;font-size:10pt;">Our performance obligations for Morningstar Credit Ratings 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 based on 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 is 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.</span><span style="font-family:Arial;font-size:10pt;"> </span><span style="font-family:Arial;font-size:10pt;">Our performance obligations for Internet advertising and Morningstar conferences are satisfied as the service is delivered, and therefore we recognize revenue when the performance obligation is satisfied (as the customer’s advertisements are displayed and at the completion of the Morningstar conference).</span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">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.</span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">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 condensed consolidated financial statements.</span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;"><br/></span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">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. </span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;"><br/></span></div>

Expenses are recognized in the Consolidated Statements of Income in a manner similar to previous accounting guidance. Topic 842 originally required the use of a modified retrospective approach upon adoption. In July 2018, the FASB issued ASU No. 2018-11, </span><span style="font-family:Arial;font-size:10pt;font-style:italic;">Leases </span><span style="font-family:Arial;font-size:10pt;">(Topic 842)</span><span style="font-family:Arial;font-size:10pt;font-style:italic;"> - Targeted Improvements</span><span style="font-family:Arial;font-size:10pt;">, which allows an additional transition method to adopt the new lease standard at the adoption date instead of the beginning of the earliest period presented. We elected this transition method at the adoption date of January 1, 2019. </span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;"><br/></span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">We also chose to elect the following practical expedients upon adoption: not to reassess whether any expired or existing contracts are or contain leases, not to reassess the lease classification for any expired or existing leases, not to reassess initial direct costs for any existing leases, and not to separately identify lease and nonlease components (i.e. maintenance costs) except for real estate leases. Additionally, we elected the short-term lease exemption, and are only applying the requirements of Topic 842 to long-term leases (leases greater than 1 year).</span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;"><br/></span></div><div style="line-height:120%;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">The adoption of Topic 842 resulted in the presentation of </span><span style="font-family:Arial;font-size:10pt;"><span>$118.8 million</span></span><span style="font-family:Arial;font-size:10pt;"> of operating lease assets and </span><span style="font-family:Arial;font-size:10pt;"><span>$145.8 million</span></span><span style="font-family:Arial;font-size:10pt;"> of operating lease liabilities on the consolidated balance sheet as of March 31, 2019. At implementation, we also reclassified </span><span style="font-family:Arial;font-size:10pt;"><span>$27.9 million</span></span><span style="font-family:Arial;font-size:10pt;"> in deferred rent liabilities related to these leases, which decreased recognized operating lease assets. The new standard did not have a material impact on the statement of income. See Note 12 for additional information. </span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;">Income Statement-Reporting Comprehensive Income: </span><span style="font-family:Arial;font-size:10pt;">On February 14, 2018, the FASB issued ASU No. 2018-02, </span><span style="font-family:Arial;font-size:10pt;font-style:italic;">Income Statement-Reporting Comprehensive Income </span><span style="font-family:Arial;font-size:10pt;">(Topic 220)</span><span style="font-family:Arial;font-size:10pt;font-style:italic;">: Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income</span><span style="font-family:Arial;font-size:10pt;">, to address a specific consequence of the Tax Reform Act by allowing a reclassification from accumulated other comprehensive income (loss) to retained earnings for stranded tax effects resulting from the Tax Reform Act’s reduction of the U.S. federal corporate income tax rate. The new standard became effective for us on January 1, 2019 and is to be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Reform Act is recognized. We did not elect to reclassify any stranded tax effects from accumulated other comprehensive income (loss) to retained earnings; therefore, the adoption did not have an impact on our consolidated financial statements and related disclosures.</span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;">Compensation—Stock Compensation: </span><span style="font-family:Arial;font-size:10pt;">On June 20, 2018, the FASB issued ASU No. 2018-07, </span><span style="font-family:Arial;font-size:10pt;font-style:italic;">Compensation—Stock Compensation </span><span style="font-family:Arial;font-size:10pt;">(Topic 718)</span><span style="font-family:Arial;font-size:10pt;font-style:italic;"> - Improvements to Nonemployee Share-Based Payment Accounting, </span><span style="font-family:Arial;font-size:10pt;">which aligns the accounting for share-based payment awards issued to employees and nonemployees. Under the new standard, the existing employee guidance will apply to nonemployee share-based transactions (as long as the transaction is not effectively a form of financing), with the exception of specific guidance related to the attribution of compensation cost. The cost of nonemployee awards will continue to be recorded as if the grantor had paid cash for the goods or services. In addition, the contractual term can be used in lieu of an expected term in the option-pricing model for nonemployee awards. The new standard became effective for us on January 1, 2019 and will be applied to all new awards granted after the date of adoption. The adoption did not have an impact on our consolidated financial statements and related disclosures.</span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;">Codification Improvements to Investments - Debt and Equity Securities</span><span style="font-family:Arial;font-size:10pt;">: On July 17, 2018, the FASB issued ASU No. 2018-09, </span><span style="font-family:Arial;font-size:10pt;font-style:italic;">Codification Improvements </span><span style="font-family:Arial;font-size:10pt;">(ASU No. 2018-09), which modifies the disclosure requirements on debt and equity securities related to ASC 320, </span><span style="font-family:Arial;font-size:10pt;font-style:italic;">Investments - Debt and Equity Securities</span><span style="font-family:Arial;font-size:10pt;">. ASU No. 2018-09 removes the requirement for these disclosures when an entity provides summarized interim financial information. The new standard became effective for us on January 1, 2019.

ASU No. 2016-13 limits the amount of credit losses to be recognized for available-for-sale debt securities to the amount by which carrying value exceeds fair value and also requires the reversal of previously recognized credit losses if fair value increases. On April 25, 2019, the FASB issued ASU No. 2019-04, </span><span style="font-family:Arial;font-size:10pt;font-style:italic;">Codification Improvements </span><span style="font-family:Arial;font-size:10pt;">(ASU No. 2019-04), which clarifies certain aspects of accounting for credit losses. On May 15, 2019, the FASB issued ASU No. 2019-05, </span><span style="font-family:Arial;font-size:10pt;font-style:italic;">Financial Instruments-Credit Losses </span><span style="font-family:Arial;font-size:10pt;">(Topic 326)</span><span style="font-family:Arial;font-size:10pt;font-style:italic;">: Targeted Transition Relief </span><span style="font-family:Arial;font-size:10pt;">(ASU No. 2019-05), which allows entities to elect the fair value option on certain financial instruments. The new standard became effective for us on January 1, 2020 and is to be applied as a cumulative-effect adjustment to retained earnings. We believe that the most notable impact of these standards relate to our processes around the assessment of the adequacy of our allowance for doubtful accounts on accounts receivable and the recognition of credit losses. We are evaluating the effect that ASU No. 2016-13, ASU No. 2019-04, and ASU No. 2019-05 will have on our consolidated financial statements and related disclosures. </span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;">Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement:</span><span style="font-family:Arial;font-size:10pt;"> On August 28, 2018, the FASB issued ASU No. 2018-13</span><span style="font-family:Arial;font-size:10pt;font-style:italic;">, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement </span><span style="font-family:Arial;font-size:10pt;">(ASU No. 2018-13)</span><span style="font-family:Arial;font-size:10pt;font-style:italic;">, </span><span style="font-family:Arial;font-size:10pt;">which eliminates, adds and modifies certain disclosure requirements around items such as transfers between Level 1 and 2, policy of timing of transfers, and valuation process for Level 3. The new standard became effective for us on January 1, 2020. As we only have Level 1 investments, the adoption of ASU No. 2018-13 will have no impact on our consolidated financial statements and related disclosures.</span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;">Cloud Computing</span><span style="font-family:Arial;font-size:10pt;">: On August 29, 2018, the FASB issued ASU No. 2018-15, </span><span style="font-family:Arial;font-size:10pt;font-style:italic;">Customer's Accounting for Fees Paid in a Cloud Computing Arrangement</span><span style="font-family:Arial;font-size:10pt;">, which helps entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement (CCA) by providing guidance for determining when an arrangement includes a software license and when an arrangement is solely a hosted CCA service. Under the new standard, customers will apply the same criteria for capitalizing implementation costs as they would for an arrangement that has a software license. The new guidance also prescribes the balance sheet, income statement, and cash flow classification of the capitalized implementation costs and related amortization expense, and requires additional quantitative and qualitative disclosures. The new standard became effective for us on January 1, 2020. Early adoption is permitted, including adoption in any interim period for which financial statements have not been issued. Entities can choose to adopt the new guidance prospectively to eligible costs incurred on or after the date this guidance is first applied or retrospectively. We will apply the new guidance prospectively to eligible costs incurred on or after the effective date. We are evaluating the effect that ASU No. 2018-15 will have on our consolidated financial statements and related disclosures.</span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;">Income Taxes: </span><span style="font-family:Arial;font-size:10pt;">On December 18, 2019, the FASB issued ASU No. 2019-12, </span><span style="font-family:Arial;font-size:10pt;font-style:italic;">Simplifying the Accounting for Income Taxes</span><span style="font-family:Arial;font-size:10pt;">, 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 is effective for us on January 1, 2021. Early adoption is permitted. We have not made a decision on early adoption. We are evaluating the effect that ASU No. 2019-12 will have on our consolidated financial statements and related disclosures.</span></div>
