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, revenue, 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, 2015, filed with the SEC on February 26, 2016.

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

Summary of Significant Accounting Policies

We discuss our significant accounting policies in Note 2 of our Audited Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2015, filed with the SEC on February 26, 2016.

On May 28, 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The original effective date for ASU 2014-09 would have required the Company to adopt beginning on January 1, 2017. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers - Deferral of the Effective Date, which defers the effective date of ASU 2014-09 for one year and permits early adoption as early as the original effective date of ASU 2014-09. The new standard is effective for us on January 1, 2018. The standard permits the use of either the retrospective or cumulative effect transition method. We are evaluating the effect that ASU No. 2014-09 will have on our consolidated financial statements and related disclosures. We have not yet selected a transition method nor have we determined the effect of the standard on our ongoing financial reporting.

On March 17, 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers - Principal versus Agent Considerations (Reporting Revenue Gross versus Net), which provides guidance on assessing whether an entity is a principal or an agent in a revenue transaction and whether an entity reports revenue on a gross or net basis. On April 14, 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers - Identifying Performance Obligations and Licensing, which provides guidance on identifying performance obligations and accounting for licenses of intellectual property. On May 6, 2016, the FASB issued ASU No. 2016-11, Revenue Recognition and Derivatives and Hedging - Rescission of SEC guidance because of ASU No. 2014-09 and ASU No. 2014-16 pursuant to staff announcements at the March 3, 2016 EITF Meeting, which rescinds the following SEC Staff Observer comments from ASC 605, Revenue Recognition, upon an entity's early adoption of ASC 606, Revenue from Contracts with Customers: Revenue and expense recognition for freight services in process, accounting for shipping and handling fees and costs, and accounting for consideration given by a vendor to a customer (including reseller of the vendor's products). On May 9, 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers - Narrow-Scope Improvements and Practical Expedients, which makes narrow-scope amendments to ASU No. 2014-09 and provides practical expedients to simplify the transition to the new standard and clarify certain aspects of the standard.

The effective date and transition requirements for ASU No. 2016-08, ASU No. 2016-10, ASU No. 2016-11, and ASU No. 2016-12 are the same as the effective date and transition requirements of ASU No. 2014-09. We are evaluating the effect that ASU No. 2016-08, ASU No. 2016-10, ASU No. 2016-11, and ASU No. 2016-12 will have on our consolidated financial statements and related disclosures.

On February 25, 2016, the FASB issued ASU No. 2016-02, Leases, 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 is effective for us on January 1, 2019. The new standard must be adopted using a modified retrospective transition, and provides for certain practical expedients. Transition will require application of the new guidance at the beginning of the earliest comparative period presented. We are evaluating the effect that ASU No. 2016-02 will have on our consolidated financial statements and related disclosures.

On March 15, 2016, the FASB issued ASU No. 2016-07, Simplifying the Transition to the Equity Method of Accounting, which eliminates the requirement to apply the equity method of accounting retrospectively when a reporting entity obtains significant influence over a previously held investment. The new standard is effective for us on January 1, 2017. Early adoption is permitted. The new standard should be applied prospectively for investments that qualify for the equity method of accounting after the effective date. We elected to early adopt ASU No. 2016-07 in the quarter ended March 31, 2016. The adoption of ASU No. 2016-07 did not have a material effect on our consolidated financial statements.

On March 30, 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting, which includes amendments to accounting for income taxes at settlement, forfeitures, and net settlements to cover withholding taxes. The new standard is effective for us on January 1, 2017. Early adoption is permitted but requires all elements of the amendments to be adopted at once rather than individually. We elected to early adopt ASU No. 2016-09 in the quarter ended June 30, 2016, which requires us to reflect any adjustments as of January 1, 2016, the beginning of the annual period that includes the interim period of adoption. The primary impact of adoption was the recognition of excess tax benefits in our provision for income taxes rather than paid in capital for all periods in fiscal year 2016. Additional amendments to the accounting for income taxes and minimum statutory withholding tax requirements had no impact to retained earnings as of January 1, 2016, where the cumulative effective of these changes are required to be recorded. We have elected to continue to estimate forfeiture expected to occur to determine the amount of compensation cost to be recognized in each period.

We elected to apply the presentation requirements for cash flows related to excess tax benefits retrospectively to all periods presented which resulted in an increase to both net cash provided by operating activities and net cash used for financing activities of $1.0 million and $2.1 million for the three and six months ended June 30, 2015, respectively. The presentation requirements for cash flows related to employee taxes paid for withheld shares had no impact to any of the periods presented in our consolidated cash flow statements because such cash flows have historically been presented as a financing activity.

Adoption of the new standard resulted in the recognition of excess tax benefits in our provision for income taxes rather than paid in capital of $0.8 million for the three and six months ended June 30, 2016. The adoption did not have a material effect on our previously reported results for the quarter ended March 31, 2016 as most of our stock options and restricted stock units vest in the second quarter.

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 one reportable segment, all required financial segment information can be found directly in the Unaudited Condensed Consolidated Financial Statements.

The accounting policies for our single reportable segment are the same as those described in “Note 2. Summary of Significant Accounting Policies” included in our Annual Report on Form 10-K for the year ended December 31, 2015. We evaluate the performance of our reporting segment based on revenue and operating income.

Investments and Fair Value Measurements

We classify our investments into three categories: available-for-sale, held-to-maturity, and 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. We classify our investment portfolio as shown below:

Our effective tax rate in the second quarter and for the first six months of 2016 was 32.7% and 33.2%, a respective decrease of 4.0 and 2.0 percentage points compared with the same periods a year ago. During the second quarter of 2016, we adopted ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting. Adoption of the new standard resulted in recognition of excess tax benefits in our provision for income taxes rather than paid in capital, thus decreasing our income tax expense in 2016. Also, the prior period tax expense in 2015 was higher because of changes in enacted tax rates that increased our tax expense attributable to deferred tax liabilities.

Unrecognized Tax Benefits

The table below provides information concerning our gross unrecognized tax benefits as of June 30, 2016 and December 31, 2015, as well as the effect these gross unrecognized tax benefits would have on our income tax expense, if they were recognized.

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 and various state and local tax authorities in the United States, as well as tax authorities in certain non-U.S. jurisdictions. It is possible, though not likely, that the examination phase of some of these audits will conclude in 2016. It is not possible to estimate the effect of current audits on previously recorded unrecognized tax benefits.

We have not provided federal and state income taxes on accumulated undistributed earnings of certain foreign subsidiaries because these earnings have been permanently reinvested. Approximately 79% of our cash, cash equivalents, and investments balance as of June 30, 2016 was held by our operations outside of the United States. 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. It is not practical to determine the amount of the unrecognized deferred tax liability related to the undistributed earnings.
 
Certain of our non-U.S. operations have incurred net operating losses (NOLs) which may become deductible to the extent these operations become profitable. For each of our operations, we evaluate whether it is more likely than not that the tax benefits related to NOLs will be realized. As part of this evaluation, we consider evidence such as tax planning strategies, historical operating results, forecasted taxable income, and recent financial performance. In the year that certain non-U.S. operations record a loss, we do not recognize a corresponding tax benefit, thus increasing our effective tax rate. Upon determining that it is more likely than not that the NOLs will be realized, we reduce the tax valuation allowances related to these NOLs, which results in a reduction to our income tax expense and our effective tax rate in the period.

We are involved in legal proceedings and litigation that have arisen in the normal course of our business. Although the outcome of a particular proceeding can never be predicted, 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.
Share Repurchase Program
Share Repurchase Program
Share Repurchase Program
 
We have an ongoing authorization, originally approved by our board of directors in September 2010 and subsequently amended, to repurchase up to $1.0 billion in shares of our outstanding common stock. The authorization expires on December 31, 2017. We may repurchase shares from time to time at prevailing market prices on the open market or in private transactions in amounts that we deem appropriate.

As of June 30, 2016, we had repurchased a total of 9,880,917 shares for $662.3 million under this authorization, leaving approximately $337.7 million available for future repurchases.
Summary of Significant Accounting Policies (Policies)
Segment Reporting Policy 
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 one reportable segment, all required financial segment information can be found directly in the Unaudited Condensed Consolidated Financial Statements.

The accounting policies for our single reportable segment are the same as those described in “Note 2. Summary of Significant Accounting Policies” included in our Annual Report on Form 10-K for the year ended December 31, 2015. We evaluate the performance of our reporting segment based on revenue and operating income.

Investments- Debt and Equity Securities Policy 
We classify our investments into three categories: available-for-sale, held-to-maturity, and 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. We classify our investment portfolio as shown below:
