In August 2015, the FASB issued ASU No. 2015-14, </font><font style="font-family:Arial;font-size:10pt;font-style:italic;">Revenue from Contracts with Customers</font><font style="font-family:Arial;font-size:10pt;">—</font><font style="font-family:Arial;font-size:10pt;font-style:italic;">Deferral of the Effective Date</font><font style="font-family:Arial;font-size:10pt;">, which deferred the effective date of ASU 2014-09 for one year and permitted early adoption as early as the original effective date. We elected the deferral, and the new standard was effective for us on January 1, 2018. We also adopted ASU No. 2016-08, ASU No. 2016-10, ASU No. 2016-11, ASU No. 2016-12, and ASU No. 2016-20 on January 1, 2018.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">We adopted Topic 606 using the modified retrospective transition method applied to those contracts which were not completed as of January 1, 2018. Upon adoption, we recognized the cumulative effect of adopting this guidance as an adjustment to our opening balance of retained earnings.

January 26, 2017, the FASB issued ASU No. 2017-04, </font><font style="font-family:Arial;font-size:10pt;font-style:italic;">Intangibles</font><font style="font-family:Arial;font-size:10pt;">—</font><font style="font-family:Arial;font-size:10pt;font-style:italic;">Goodwill and Other</font><font style="font-family:Arial;font-size:10pt;">, which simplifies the accounting for goodwill impairment. The guidance removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. All other goodwill impairment guidance will remain largely unchanged. Entities will continue to have the option to perform a qualitative assessment to determine if a quantitative impairment test is necessary. The same one-step impairment test will be applied to goodwill at all reporting units, even those with zero or negative carrying amounts. Entities will be required to disclose the amount of goodwill at reporting units with zero or negative carrying amounts. The new standard is effective for us on January 1, 2020. The new standard is required to be applied prospectively. Early adoption is permitted for any impairment tests performed after January 1, 2017. We elected to early adopt the new standard on October 1, 2018 as we perform our annual impairment review in the fourth quarter. The adoption did not have an impact on our consolidated financial statements and related disclosures.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;font-style:italic;">Recently Issued Accounting Pronouncements Not Yet Adopted</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;font-style:italic;">Leases:</font><font style="font-family:Arial;font-size:10pt;"> On February 25, 2016, the FASB issued ASU No. 2016-02, </font><font style="font-family:Arial;font-size:10pt;font-style:italic;">Leases (Topic 842)</font><font style="font-family:Arial;font-size:10pt;">, which will require lessees to recognize almost all leases on their balance sheet as a right-of-use asset and a lease liability. The new standard became effective for us on January 1, 2019. The new standard originally required the use of a modified retrospective approach upon adoption. In July 2018, the FASB issued ASU No. 2018-11, </font><font style="font-family:Arial;font-size:10pt;font-style:italic;">Leases (Topic 842) - Targeted Improvements</font><font 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, and recognize a cumulative-effect adjustment to the beginning balance of retained earnings in the period of adoption. We elected this transition method at the adoption date of January 1, 2019. We continue to evaluate the effect that the new standard will have on our consolidated financial statements and related disclosures. We are making meaningful progress on our implementation plan and are achieving project milestones, including a comprehensive review of our lease portfolio to identify all leases where the company is either a lessor or lessee. In addition, we implemented lease accounting software in early 2019 to assist in our ongoing lease data collection, tracking and analysis, and are updating our lease processes and related internal controls to reflect changes required to ensure readiness for adoption. We are updating our accounting policies and plan to make an accounting policy election to keep leases with an initial term of 12 months or less off of the balance sheet. We also plan to recognize those lease payments in the Consolidated Statements of Income on a straight-line basis over the lease term. We do not believe the new standard will have a material impact on our liquidity. The adoption of the new lease standard will have no impact on our debt-covenant compliance under our current agreements.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;font-style:italic;">Income Statement-Reporting Comprehensive Income: </font><font style="font-family:Arial;font-size:10pt;">On February 14, 2018, the FASB issued ASU No. 2018-02, </font><font style="font-family:Arial;font-size:10pt;font-style:italic;">Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income</font><font 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.

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.

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 is 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.

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. Amounts invoiced in excess of the revenue recognized for the services transferred during the period will result in an increase to deferred revenue. The timing of cash payments is typically </font><font style="font-family:Arial;font-size:10pt;">thirty</font><font style="font-family:Arial;font-size:10pt;"> to </font><font style="font-family:Arial;font-size:10pt;">sixty</font><font style="font-family:Arial;font-size:10pt;"> days after the performance obligation has been satisfied and these payments reduce our outstanding accounts receivable.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font 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.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">License-based revenue is generated through subscription contracts 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 product or service during the term of the subscription license and the level of service is consistent during the contract period. Therefore, we recognize revenue for these performance obligations on a straight-line basis, typically over terms of </font><font style="font-family:Arial;font-size:10pt;">12</font><font style="font-family:Arial;font-size:10pt;"> to </font><font style="font-family:Arial;font-size:10pt;">36 months</font><font style="font-family:Arial;font-size:10pt;">.</font></div><div style="line-height:120%;text-align:left;padding-left:22px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font 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 satisfied over time as the customer receives continuous access to a service for the contract term. We recognize revenue 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 </font><font style="font-family:Arial;font-size:10pt;">30</font><font style="font-family:Arial;font-size:10pt;">-</font><font style="font-family:Arial;font-size:10pt;">55</font><font 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 </font><font style="font-family:Arial;font-size:10pt;">12</font><font style="font-family:Arial;font-size:10pt;"> to </font><font style="font-family:Arial;font-size:10pt;">36 months</font><font 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 variable consideration is included in the initial transaction price only to the extent it is probable that a significant reversal in the amount of revenue recognized will not occur. Estimates of asset-based fees are based on the most recently reported quarter, and, as a result, it is unlikely a significant reversal of revenue would occur. </font></div><div style="line-height:120%;text-align:left;padding-left:22px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">Transaction-based revenue is generated through contracts with our customers for Internet advertising, Morningstar Conferences, and Morningstar Credit Ratings. 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). 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.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font 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.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font 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 license obligations. In these arrangements, the customer has contracted to receive a single, 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.</font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">We record taxes imposed on revenue-producing transactions (such as sales, use, value-added, and some excise taxes) on a net basis; therefore, we exclude such taxes from revenue in our Consolidated Statements of Income.</font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;font-size:10pt;"><font 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. Certain arrangements may have cancellation or refund provisions. If we make a refund, it typically reflects the amount collected from a customer for which we have not yet provided services. The refund therefore results in a reduction of deferred revenue.</font></div></div>
