General	Note One — General In the opinion of management, the accompanying unaudited condensed consolidated financial statements of Mattersight Corporation (“we,” “Mattersight,” or the “Company”) include all normal and recurring adjustments necessary for a fair presentation of our condensed consolidated financial position as of September 30, 2015 and December 31, 2014, the condensed consolidated results of our operations for the three months and nine months ended September 30, 2015 and September 30, 2014, the condensed consolidated statements of our comprehensive loss for the three months and nine months ended September 30, 2015 and September 30, 2014, and our condensed consolidated cash flows for the nine months ended September 30, 2015 and September 30, 2014, and are in accordance with United States generally accepted accounting principles (“GAAP”) and in conformity with Securities and Exchange Commission (“SEC”) Article 8-03 of Regulation S-X; provided, that certain information and disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto in Mattersight’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014 filed with the SEC on March 12, 2015. The results of operations for the three months and nine months ended September 30, 2015 are not necessarily indicative of the results to be expected for the full year. The preparation of financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.

The 2014 revenue and expense classifications have been revised to conform to our current presentation.

Text Block [Abstract]
Revenue Recognition	Note Three — Revenue Recognition Revenue Recognition Subscription Revenue Subscription revenue consists of Subscription revenue derived from Mattersight’s Behavioral Analytics service offerings, including Predictive Behavioral Routing, Performance Management, Quality Assurance, and Predictive Analytics and Marketing Managed Services revenue derived from the performance of services on a continual basis. Subscription revenue is based on a number of factors, such as the number of users to whom the Company provides one or more of its Behavioral Analytics offerings, the type and number of Behavioral Analytics offerings deployed to the client, and in some cases, the number of hours of calls analyzed during the relevant month of the subscription period. Subscription periods generally range from three to five years after the go-live date or, in cases where the Company contracts with a client for a short-term pilot of a Behavioral Analytics offering prior to committing to a longer subscription period, if any, the subscription or pilot periods generally range from three to twelve months after the go-live date. This revenue is recognized over the applicable subscription period, as the service is performed for the client. Other Revenue Other revenue consists of Deployment revenue, Professional Services revenue, and Reimbursed Expenses revenue. Deployment revenue consists of planning, deployment, and training fees derived from Behavioral Analytics contracts. These fees, which are considered to be installation fees related to Behavioral Analytics subscription contracts, are deferred until the installation is complete and are then recognized over the applicable subscription period. In cases where the Company contracts with a client for a short-term pilot of a Behavioral Analytics offering prior to committing to a longer subscription period, if any, the period in which pilot deployment revenue is recognized generally ranges from three to twelve months after the go-live date. Installation costs incurred are deferred up to an amount not to exceed the amount of deferred installation revenue and additional amounts that are recoverable based on the contractual arrangement. These costs are included in Prepaid expenses and Other long-term assets. Such costs are amortized over the subscription period. Costs in excess of the foregoing revenue amount are expensed in the period incurred. Professional Services revenue primarily consists of fees charged to the Company’s clients to provide post-deployment follow-on consulting services, which include custom data analysis, the implementation of enhancements, and training, as well as fees generated from the Company’s operational consulting services. Professional Services are performed for the Company’s clients on a fixed-fee or time-and-materials basis. Revenue is recognized as the services are performed, with performance generally assessed on the ratio of actual hours incurred to-date compared to the total estimated hours over the entire term of the contract. Reimbursed Expenses revenue includes billable costs related to travel and other out-of-pocket expenses incurred while performing services for the Company’s clients. The cost of third-party product and support may be included within this category if the transaction does not satisfy the requirements for gross reporting. An equivalent amount of reimbursable expenses is included in Total cost of revenue.

If the Company’s Board of Directors were to declare a semi-annual cash dividend on the Series B Stock for dividend periods subsequent to July 1, 2015, each dividend payment period would be approximately $0.3 million on the 1,644,768 shares of Series B Stock issued and outstanding as of September 30, 2015, at the cash dividend rate of $0.1785. (2) In periods in which there was a loss, the effect of Common Stock equivalents, which is primarily related to the Series B Stock, was not included in the diluted loss per share calculation as it was antidilutive.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note Sixteen — The Company reports certain assets and liabilities at fair value. Fair value is an exit price and establishes a three-tier valuation hierarchy for ranking the quality and reliability of the information used to determine fair values. The first tier, Level 1, uses quoted market prices in active markets for identical assets or liabilities. Level 2 uses inputs, other than quoted market prices for identical assets or liabilities in active markets, which are observable either directly or indirectly. Level 3 uses unobservable inputs in which there are little or no market data, and requires the entity to develop its own assumptions. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The following table provides the assets and liabilities carried at fair value measured on a recurring basis as of September 30, 2015 and December 31, 2014: (In millions) Fair Value Measurements at September 30, 2015 Using Total carrying value at September 30, 2015 Quoted Active Markets (Level 1) Other Observable (Level 2) Significant Unobservable (Level 3) Money market fund $ 20.1 $ 20.1 $ — $ — Warrant liability $ — $ — $ — $ — Fair Value Measurements at December 31, 2014 Using Total carrying value at December Quoted Prices in Active Markets (Level 1) Other Observable (Level 2) Significant Unobservable (Level 3) Money market fund $ 13.7 $ 13.7 $ — $ — Warrant liability $ 0.4 $ — $ — $ 0.4 The following table represents the activity in the Company’s Level 3 warrants: (In millions) Amount Level 3 warrants, end of period at December 31, 2014 $ 0.4 Change in fair value of warrant liability — Warrant exercise (0.4 ) Level 3 warrants, end of period at September 30, 2015 $ —

Accounting Changes And Error Corrections [Abstract]
Recent Accounting Pronouncements	Note Eighteen — Recent Accounting Pronouncements In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2015-05, “Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40).” The pronouncement was issued to provide guidance concerning accounting for fees in a cloud computing arrangement. The pronouncement is effective for reporting periods beginning after December 15, 2015. The adoption of ASU 2015-05 is not expected to have a material impact on the Company’s condensed consolidated financial statements. In November 2014, FASB issued ASU No. 2014-16, Derivatives and Hedging (Topic 815): Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share Is More Akin to Debt or to Equity (“ASU 2014-16”). ASU 2014-16 does not change the current criteria in GAAP for determining when separation of certain embedded derivative features in a hybrid financial instrument is required, but clarifies how current GAAP should be interpreted in the evaluation of the economic characteristics and risks of a host contract in a hybrid financial instrument that is issued in the form of a share, reducing existing diversity in practice. The adoption of this ASU is not expected to have a material impact on the Company’s condensed consolidated financial statements. In August 2014, FASB issued ASU No. 2014-15: Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern (“ASU 2014-15”). The update sets forth a requirement for management to evaluate whether there are conditions and events that raise substantial doubt about an entity's ability to continue as a going concern, a responsibility that did not previously exist in U.S. GAAP. The amendments included in this update require management to assess an entity’s ability to continue as a going concern by incorporating and expanding upon certain principles that are currently in U.S. auditing standards. Specifically, the amendments (i) provide a definition of the term substantial doubt, (ii) require an evaluation every reporting period, including interim periods, (iii) provide principles for considering the mitigating effect of management’s plans, (iv) require certain disclosures when substantial doubt is alleviated as a result of consideration of management’s plans, (v) require an express statement and other disclosures when substantial doubt is not alleviated, and (vi) require an assessment for a period of one year after the date that the financial statements are issued (or available to be issued). ASU 2014-15 will be effective for the Company in fiscal year 2016. The adoption of this ASU is not expected to have a material impact on the Company’s condensed consolidated financial statements. In May 2014, FASB issued ASU No. 2014-09: Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”). The guidance sets forth a new five-step revenue recognition model that replaces the prior revenue recognition guidance in its entirety and is intended to eliminate numerous industry-specific pieces of revenue recognition guidance that have historically existed in U.S. GAAP. The underlying principle of the new standard is that a business or other organization will recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects what it expects in exchange for the goods or services. ASU 2014-09 provides alternative methods of initial adoption and is effective for annual periods beginning after December 15, 2017 and interim periods within those annual periods. Early adoption is not permitted. The Company is currently evaluating the impact that this standard will have on the Company’s condensed consolidated financial statements.

Commitments And Contingencies Disclosure [Abstract]
Litigation and Other Contingencies	Note Twenty — Litigation and Other Contingencies The Company is a party to various agreements, including all client contracts, under which it may be obligated to indemnify the other party with respect to certain matters, including, but not limited to, indemnification against third-party claims of infringement of intellectual property rights with respect to services, software, and other deliverables provided by the Company. These obligations may be subject to various limitations on the remedies available to the other party, including, without limitation, limits on the amounts recoverable and the time during which claims may be made, and may be supported by indemnities given to the Company by applicable third parties. Payment by the Company under these indemnification clauses is generally subject to the other party making a claim that is subject to challenge by the Company. Historically, the Company has not been obligated to pay any claim for indemnification under its agreements, and management is not aware of future indemnification payments that it would be obligated to make. Under its By-Laws, subject to certain exceptions, the Company has agreed to indemnify its corporate officers and directors for certain events or occurrences while the officer or director is, or was, serving at its request in such capacity or in certain related capacities. The Company has separate indemnification agreements with each of its directors and corporate officers that requires it, subject to certain exceptions, to indemnify them to the fullest extent authorized or permitted by its By-Laws and the Delaware General Corporation Law. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited; however, the Company has a director and officer liability insurance policy that limits its exposure and enables it to recover a portion of any amounts paid under these indemnification agreements. As a result of its insurance policy coverage, the Company believes the estimated fair value of these indemnification agreements is minimal. The Company had no liabilities recorded for these agreements as of September 30, 2015.
