Summary of Significant Accounting Policies
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries and have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) and include the assets, liabilities, results of operations and cash flows of the Company. All significant intercompany accounts and transactions have been eliminated in consolidation.
Reclassifications	Reclassifications Certain prior period amounts in the condensed consolidated balance sheets, condensed consolidated statements of cash flows and the notes thereto have been reclassified to conform to the current period’s presentation. Specifically, capitalized technology costs have been reclassified out of property and equipment and have been combined with capitalized content development costs. Also, prior period working capital amounts in the condensed consolidated statements of cash flows have been reclassified within operating activities. None of these reclassifications had any impact on total assets, net cash used in operating activities or investing activities previously reported for any periods presented.
Unaudited Condensed Consolidated Financial Information	Unaudited Condensed Consolidated Financial Information The accompanying unaudited condensed consolidated financial statements and accompanying notes have been prepared in accordance with U.S. GAAP. The Company has condensed or omitted certain information and footnote disclosures normally included in financial statements presented in accordance with U.S. GAAP in the accompanying unaudited condensed consolidated financial statements. In the opinion of management, the interim financial information includes all adjustments of a normal recurring nature necessary for a fair presentation of financial position, the results of operations, changes in stockholders’ equity and cash flows, and the disclosures made herein are adequate to prevent the information presented from being misleading. The results of operations for the three and nine months ended September 30, 2016 are not necessarily indicative of the results for the full year ending December 31, 2016 or the results for any future periods. These unaudited condensed consolidated interim financial statements should be read in conjunction with the audited consolidated financial statements and related notes for the year ended December 31, 2015, which are included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (the “SEC”) on March 10, 2016.
Use of Estimates	Use of Estimates The preparation of financial statements in accordance with U.S. GAAP requires management to make certain estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. On an ongoing basis, the Company evaluates its estimates, including those related to the useful lives of long-lived assets, fair value measurements and income taxes, among others. The Company bases its estimates and assumptions on historical experience and on various other factors that it believes to be reasonable under the circumstances. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may be affected by changes in those estimates. The Company evaluates its estimates and assumptions on an ongoing basis.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that subject the Company to significant concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. All of the Company’s cash is held at financial institutions that management believes to be of high credit quality. The Company’s bank accounts exceed federally insured limits at times. The Company has not experienced any losses on cash to date. To manage accounts receivable risk, the Company maintains an allowance for doubtful accounts, if needed. During the three months ended September 30, 2016, three clients each accounted for 10% or more of the Company’s revenue, as follows: $18.4 million, $8.7 million and $5.5 million, which equals 35%, 17% and 11% of total revenue, respectively. During the three months ended September 30, 2015, three clients each accounted for 10% or more of the Company’s revenue, as follows: $15.9 million, $5.7 million and $4.3 million, which equals 43%, 15% and 12% of total revenue, respectively. During the nine months ended September 30, 2016, three clients each accounted for 10% or more of the Company’s revenue, as follows: $53.9 million, $25.5 million and $15.8 million, which equals 36%, 17% and 11% of total revenue, respectively. During the nine months ended September 30, 2015, four clients each accounted for 10% or more of the Company’s revenue, as follows: $49.2 million, $16.0 million, $12.7 million and $10.1 million, which equals 46%, 15%, 12% and 10% of total revenue, respectively. Additionally, as of September 30, 2016, four clients each accounted for 10% or more of the Company’s accounts receivable balance, as follows: $8.2 million, $5.1 million, $2.6 million and $2.5 million, which equals 39%, 24%, 12% and 12% of total accounts receivable, respectively. As of December 31, 2015, two clients each accounted for 10% or more of the Company’s accounts receivable balance, as follows: $0.2 million and $0.1 million, which equals 18% and 7% of total accounts receivable, respectively.
Property and Equipment	Property and Equipment Property and equipment is stated at cost less accumulated depreciation and amortization. Expenditures for major additions, construction and improvements are capitalized. Depreciation and amortization is expensed using the straight-line method over the estimated useful lives of the related assets, which range from three to five years for computer hardware and five to seven years for furniture and office equipment. Leasehold improvements are depreciated on a straight-line basis over the lesser of the remaining term of the leased facility or the estimated useful life of the improvement, which ranges from four to ten years. Useful lives of significant assets are periodically reviewed and adjusted prospectively to reflect the Company’s current estimates of the respective assets’ expected utility. Repair and maintenance costs are expensed as incurred.
Capitalized Technology and Content Development Costs	Capitalized Technology and Content Development Costs The Company capitalizes certain costs related to internal-use software, primarily consisting of direct labor associated with creating the software. Software development projects generally include three stages: the preliminary project stage (all costs are expensed as incurred), the application development stage (certain costs are capitalized and certain costs are expensed as incurred) and the post-implementation/operation stage (all costs are expensed as incurred). Costs capitalized in the application development stage include costs of designing the application, coding, integrating the Company’s and the university’s networks and systems, and the testing of the software. Capitalization of costs requires judgment in determining when a project has reached the application development stage and the period over which the Company expects to benefit from the use of that software. Once the software is placed in service, these costs are amortized on the straight-line method over the estimated useful life of the software, which is generally three years. The Company works with each client’s faculty members to develop and maintain educational content that is delivered to their students through Online Campus. The online content developed jointly by the Company and its clients consists of subjects chosen and taught by clients’ faculty members and incorporates references and examples designed to remain relevant over extended periods of time. Online delivery of the content, combined with live, face-to-face instruction, provides the Company with rapid user feedback that it uses to make ongoing corrections, modifications and improvements to the course content. The Company’s clients retain all intellectual property rights to the developed content, although the Company retains the rights to the content packaging and delivery mechanisms. Much of the Company’s new content development uses proven delivery platforms and is therefore primarily subject-specific in nature. As a result, a significant portion of content development costs qualify for capitalization due to the focus of the Company’s development efforts on the unique subject matter of the content. Similar to on-campus programs offered by the Company’s clients, the online degree programs enabled by the Company offer numerous courses for each degree. The Company therefore capitalizes its development costs on a course-by-course basis. As students must matriculate into a client program in order to take a course, revenues and identifiable cash flows are also measured at the client program level. The Company develops content on a course-by-course basis in conjunction with the faculty for each client program. The clients and their faculty generally provide course outlines in the form of the curriculum, required textbooks, case studies and other reading materials, as well as presentations that are typically used in the on-campus setting. The Company is then responsible for, and incurs all of the expenses related to, the conversion of the materials provided by each client into a format suitable for delivery through Online Campus. The content development costs that qualify for capitalization are third-party direct costs, such as videography, editing and other services associated with creating digital content. Additionally, the Company capitalizes internal payroll and payroll-related costs incurred to create and produce videos and other digital content utilized in the clients’ programs for delivery via Online Campus. Capitalization ends when content has been fully developed by both the Company and the client, at which time amortization of the capitalized content development costs begins. The capitalized costs are recorded on a course-by-course basis and included in capitalized content costs on the condensed consolidated balance sheets. These costs are amortized using the straight-line method over the estimated useful life of the respective capitalized content program, which is generally five years. The estimated useful life corresponds with the Company’s planned curriculum refresh rate. This refresh rate is consistent with expected curriculum refresh rates as cited by program faculty members for similar on-campus programs. It is reasonably possible that developed content could be refreshed before the estimated useful lives are complete or be expensed immediately in the event that the development of a course is discontinued prior to launch.
Evaluation of Long-Lived Assets	Evaluation of Long-Lived Assets The Company reviews long-lived assets, which consist of property and equipment, capitalized technology costs, capitalized content development costs and acquired finite-lived intangible assets, for impairment whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable. Recoverability of a long-lived asset is measured by a comparison of the carrying value of an asset or asset group to the future undiscounted net cash flows expected to be generated by that asset or asset group. If such assets are not recoverable, the impairment to be recognized is measured by the amount by which the carrying value of an asset exceeds the estimated fair value (discounted cash flow) of the asset or asset group. In order to assess the recoverability of the capitalized content development costs, the costs are grouped by program, which is the lowest level of independent cash flows. The Company’s impairment analysis is based upon forecasted financial and operational results. The actual results could vary from the Company’s forecasts, especially in relation to recently launched programs. For the three and nine months ended September 30, 2016 and 2015, no impairment of long-lived assets was deemed to have occurred.
Revenue Recognition and Deferred Revenue	Revenue Recognition and Deferred Revenue The Company recognizes revenue when all of the following conditions are met: (i) persuasive evidence of an arrangement exists, (ii) rendering of services is complete, (iii) fees are fixed or determinable and (iv) collection of fees is reasonably assured. The Company primarily derives its revenue from long-term contracts that typically range from 10 to 15 years in length. Under these contracts, the Company enables access to its Platform to its clients and their faculty and students. The Company is entitled to a contractually specified percentage of net program proceeds from its clients. These net program proceeds represent gross proceeds billed by clients to students, less credit card fees and other specified charges the Company has agreed to exclude in certain of its client contracts. The Company generates substantially all of its revenue from multiple-deliverable contractual arrangements with its clients. Under each of these arrangements, the Company provides (i) access to Online Campus, which serves as a learning platform for its client’s faculty and students and which also enables a comprehensive range of other client functions, (ii) access to operations applications which provide the content management, admissions application processing, customer relationship management, and other functionality necessary to effectively operate the Company’s clients’ programs and (iii) technology-enabled services that support the complete lifecycle of a higher education program, including attracting students, advising prospective students through the admissions application process, providing technical, success coaching and other support, facilitating accessibility to individuals with disabilities, and facilitating in-program field placements. In order to treat deliverables in a multiple-deliverable contractual arrangement as separate units of accounting, deliverables must have standalone value upon delivery. The technology-enabled services within the Platform are provided primarily in support of programs delivered through Online Campus, and for students of the programs delivered through Online Campus. Accordingly, the Company has determined that no individual deliverable has standalone value upon delivery and, therefore, deliverables within the Company’s multiple-deliverable arrangements do not qualify for treatment as separate units of accounting. Therefore, the Company considers all deliverables to be a single unit of accounting and recognizes revenue from the entire arrangement over the term of the service period. Advance payments are recorded as deferred revenue until services are delivered or obligations are met, at which time revenue is recognized. Deferred revenue as of a particular balance sheet date represents the excess of amounts received as compared to amounts recognized in revenue in the condensed consolidated statements of operations as of the end of the reporting period, and such amounts are reflected as a current liability on the Company’s condensed consolidated balance sheets.
Stock-Based Compensation	Stock-Based Compensation The Company accounts for stock-based compensation awards based on the fair value of the award as of the grant date. For awards subject to service-based vesting conditions, the Company recognizes stock-based compensation expense on a straight-line basis over the awards’ requisite service period, adjusted for estimated forfeitures. For awards subject to both performance and service-based vesting conditions, the Company recognizes stock-based compensation expense using an accelerated recognition method when it is probable that the performance condition will be achieved. See Note 7 for a summary of assumptions used in calculating the fair value of stock options.
Comprehensive Loss	Comprehensive Loss The Company’s net loss equals comprehensive loss for all periods presented as the Company has no material components of other comprehensive income.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In August 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The ASU addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice surrounding how certain transactions are classified in the statement of cash flows. The amendments in this ASU are effective for annual reporting periods beginning after December 15, 2017. The Company is currently evaluating the effect that this standard will have on its consolidated statements of cash flows and related disclosures. In March 2016, the FASB issued ASU No. 2016-09, Compensation —Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The ASU simplifies various aspects related to the accounting and presentation of share-based payments. The guidance also allows employers to withhold shares to satisfy minimum statutory withholding requirements up to the employees’ maximum individual tax rate without causing the award to be classified as a liability. Additionally, the guidance stipulates that cash paid by an employer to a taxing authority when directly withholding shares for tax withholding purposes should be classified as a financing activity on the statement of cash flows, and allows companies to elect an accounting policy to either estimate the share-based award forfeitures (and expense) or account for forfeitures (and expense) as they occur. The amendments in this ASU are effective for fiscal years beginning after December 15, 2016. Early adoption is permitted in any interim or annual period, with any adjustments reflected as of the beginning of the fiscal year of adoption. The Company is currently evaluating the effect that this standard will have on its consolidated financial position and related disclosures. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The ASU introduces a model for lessees requiring most leases to be reported on the balance sheet. Lessor accounting remains substantially similar to current U.S. GAAP. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018. The Company is currently evaluating the effect that this standard will have on its consolidated financial position and related disclosures. In November 2015, the FASB issued ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. The ASU eliminates the requirement to classify deferred tax assets and liabilities between current and noncurrent. The ASU requires classification of all deferred tax asset and liability balances as noncurrent. The amendments in this ASU are effective for fiscal years beginning after December 15, 2016, with early adoption permitted. Adoption of the ASU is either retrospective to each prior period presented, or prospective. As of December 31, 2015, the Company early adopted the ASU prospectively. Adoption of this standard did not have a material impact on the Company’s consolidated financial position and related disclosures. In April 2015, the FASB issued ASU No. 2015-05, Intangibles — Goodwill and Other — Internal-Use Software (Subtopic 350-40). The ASU provides guidance to customers in a cloud computing arrangement to determine whether the arrangement includes a software license. When a cloud computing arrangement includes a software license, the customer is required to account for the license element of the arrangement consistent with the acquisition of other software licenses. The amendments in this ASU are effective for fiscal years beginning after December 15, 2015. The Company adopted this ASU on January 1, 2016. Adoption of this standard did not have a material impact on the Company’s consolidated financial position and related disclosures. In April 2015, the FASB issued ASU No. 2015-03, Interest — Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. The ASU simplifies the presentation of debt issuance costs by requiring that such costs be presented in the consolidated balance sheets as a direct deduction from the carrying value of the associated debt instrument, consistent with debt discounts. Subsequent to the issuance of this ASU, the SEC staff announced that the presentation of debt issuance costs associated with line-of-credit arrangements may be presented as an asset. This announcement was codified by the FASB in ASU 2015-15. The amendments in these ASUs are effective for fiscal years beginning after December 15, 2015. The Company adopted this ASU on January 1, 2016. Adoption of this standard did not have a material impact on the Company’s consolidated financial position and related disclosures. In January 2015, the FASB issued ASU No. 2015-01, Income Statement — Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items. The ASU simplifies income statement presentation by eliminating the concept of extraordinary items. The amendments in this ASU are effective for fiscal periods beginning after December 15, 2015. The Company adopted this ASU on January 1, 2016. Adoption of this standard did not have a material impact on the Company’s consolidated financial position and related disclosures. In August 2014, the 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. The ASU requires that an entity’s management evaluate whether there are conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued. The amendments in this ASU are effective for annual reporting periods ending after December 15, 2016. The Company does not expect the new standard to have a significant impact on its reporting process. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), 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. In July 2015, the FASB deferred the mandatory effective date of this ASU by one year from January 1, 2017 to January 1, 2018. Early application is permitted, but not prior to the original effective date of January 1, 2017. Subsequently, the FASB has issued the following standards related to ASU No. 2014-09: ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations; ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing; and ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients. The Company must adopt ASU No. 2016-08, ASU No. 2016-10 and ASU 2016-12 with ASU 2014-09 (collectively, the “new revenue standards”). The new revenue standards may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of adoption. The Company is currently evaluating the effect that the new standards will have on its consolidated financial position and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the new standards on its ongoing financial reporting.

Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries and have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) and include the assets, liabilities, results of operations and cash flows of the Company. All significant intercompany accounts and transactions have been eliminated in consolidation.

Reclassifications

Certain prior period amounts in the condensed consolidated balance sheets, condensed consolidated statements of cash flows and the notes thereto have been reclassified to conform to the current period’s presentation. Specifically, capitalized technology costs have been reclassified out of property and equipment and have been combined with capitalized content development costs. Also, prior period working capital amounts in the condensed consolidated statements of cash flows have been reclassified within operating activities. None of these reclassifications had any impact on total assets, net cash used in operating activities or investing activities previously reported for any periods presented.

Unaudited Condensed Consolidated Financial Information

The accompanying unaudited condensed consolidated financial statements and accompanying notes have been prepared in accordance with U.S. GAAP. The Company has condensed or omitted certain information and footnote disclosures normally included in financial statements presented in accordance with U.S. GAAP in the accompanying unaudited condensed consolidated financial statements. In the opinion of management, the interim financial information includes all adjustments of a normal recurring nature necessary for a fair presentation of financial position, the results of operations, changes in stockholders’ equity and cash flows, and the disclosures made herein are adequate to prevent the information presented from being misleading. The results of operations for the three and nine months ended September 30, 2016 are not necessarily indicative of the results for the full year ending December 31, 2016 or the results for any future periods. These unaudited condensed consolidated interim financial statements should be read in conjunction with the audited consolidated financial statements and related notes for the year ended December 31, 2015, which are included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (the “SEC”) on March 10, 2016.

Use of Estimates

The preparation of financial statements in accordance with U.S. GAAP requires management to make certain estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. On an ongoing basis, the Company evaluates its estimates, including those related to the useful lives of long-lived assets, fair value measurements and income taxes, among others. The Company bases its estimates and assumptions on historical experience and on various other factors that it believes to be reasonable under the circumstances. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may be affected by changes in those estimates. The Company evaluates its estimates and assumptions on an ongoing basis.

Concentration of Credit Risk

Financial instruments that subject the Company to significant concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. All of the Company’s cash is held at financial institutions that management believes to be of high credit quality. The Company’s bank accounts exceed federally insured limits at times. The Company has not experienced any losses on cash to date. To manage accounts receivable risk, the Company maintains an allowance for doubtful accounts, if needed.

During the three months ended September 30, 2016, three clients each accounted for 10% or more of the Company’s revenue, as follows: $18.4 million, $8.7 million and $5.5 million, which equals 35%, 17% and 11% of total revenue, respectively. During the three months ended September 30, 2015, three clients each accounted for 10% or more of the Company’s revenue, as follows: $15.9 million, $5.7 million and $4.3 million, which equals 43%, 15% and 12% of total revenue, respectively.

During the nine months ended September 30, 2016, three clients each accounted for 10% or more of the Company’s revenue, as follows: $53.9 million, $25.5 million and $15.8 million, which equals 36%, 17% and 11% of total revenue, respectively. During the nine months ended September 30, 2015, four clients each accounted for 10% or more of the Company’s revenue, as follows: $49.2 million, $16.0 million, $12.7 million and $10.1 million, which equals 46%, 15%, 12% and 10% of total revenue, respectively.

Additionally, as of September 30, 2016, four clients each accounted for 10% or more of the Company’s accounts receivable balance, as follows: $8.2 million, $5.1 million, $2.6 million and $2.5 million, which equals 39%, 24%, 12% and 12% of total accounts receivable, respectively. As of December 31, 2015, two clients each accounted for 10% or more of the Company’s accounts receivable balance, as follows: $0.2 million and $0.1 million, which equals 18% and 7% of total accounts receivable, respectively.

Property and Equipment

Property and equipment is stated at cost less accumulated depreciation and amortization. Expenditures for major additions, construction and improvements are capitalized. Depreciation and amortization is expensed using the straight-line method over the estimated useful lives of the related assets, which range from three to five years for computer hardware and five to seven years for furniture and office equipment. Leasehold improvements are depreciated on a straight-line basis over the lesser of the remaining term of the leased facility or the estimated useful life of the improvement, which ranges from four to ten years. Useful lives of significant assets are periodically reviewed and adjusted prospectively to reflect the Company’s current estimates of the respective assets’ expected utility. Repair and maintenance costs are expensed as incurred.

Capitalized Technology and Content Development Costs

The Company capitalizes certain costs related to internal-use software, primarily consisting of direct labor associated with creating the software. Software development projects generally include three stages: the preliminary project stage (all costs are expensed as incurred), the application development stage (certain costs are capitalized and certain costs are expensed as incurred) and the post-implementation/operation stage (all costs are expensed as incurred). Costs capitalized in the application development stage include costs of designing the application, coding, integrating the Company’s and the university’s networks and systems, and the testing of the software. Capitalization of costs requires judgment in determining when a project has reached the application development stage and the period over which the Company expects to benefit from the use of that software. Once the software is placed in service, these costs are amortized on the straight-line method over the estimated useful life of the software, which is generally three years.

The Company works with each client’s faculty members to develop and maintain educational content that is delivered to their students through Online Campus. The online content developed jointly by the Company and its clients consists of subjects chosen and taught by clients’ faculty members and incorporates references and examples designed to remain relevant over extended periods of time. Online delivery of the content, combined with live, face-to-face instruction, provides the Company with rapid user feedback that it uses to make ongoing corrections, modifications and improvements to the course content. The Company’s clients retain all intellectual property rights to the developed content, although the Company retains the rights to the content packaging and delivery mechanisms.

Much of the Company’s new content development uses proven delivery platforms and is therefore primarily subject-specific in nature. As a result, a significant portion of content development costs qualify for capitalization due to the focus of the Company’s development efforts on the unique subject matter of the content. Similar to on-campus programs offered by the Company’s clients, the online degree programs enabled by the Company offer numerous courses for each degree. The Company therefore capitalizes its development costs on a course-by-course basis. As students must matriculate into a client program in order to take a course, revenues and identifiable cash flows are also measured at the client program level.

The Company develops content on a course-by-course basis in conjunction with the faculty for each client program. The clients and their faculty generally provide course outlines in the form of the curriculum, required textbooks, case studies and other reading materials, as well as presentations that are typically used in the on-campus setting. The Company is then responsible for, and incurs all of the expenses related to, the conversion of the materials provided by each client into a format suitable for delivery through Online Campus.

The content development costs that qualify for capitalization are third-party direct costs, such as videography, editing and other services associated with creating digital content. Additionally, the Company capitalizes internal payroll and payroll-related costs incurred to create and produce videos and other digital content utilized in the clients’ programs for delivery via Online Campus. Capitalization ends when content has been fully developed by both the Company and the client, at which time amortization of the capitalized content development costs begins. The capitalized costs are recorded on a course-by-course basis and included in capitalized content costs on the condensed consolidated balance sheets. These costs are amortized using the straight-line method over the estimated useful life of the respective capitalized content program, which is generally five years. The estimated useful life corresponds with the Company’s planned curriculum refresh rate. This refresh rate is consistent with expected curriculum refresh rates as cited by program faculty members for similar on-campus programs. It is reasonably possible that developed content could be refreshed before the estimated useful lives are complete or be expensed immediately in the event that the development of a course is discontinued prior to launch.

Evaluation of Long-Lived Assets

The Company reviews long-lived assets, which consist of property and equipment, capitalized technology costs, capitalized content development costs and acquired finite-lived intangible assets, for impairment whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable. Recoverability of a long-lived asset is measured by a comparison of the carrying value of an asset or asset group to the future undiscounted net cash flows expected to be generated by that asset or asset group. If such assets are not recoverable, the impairment to be recognized is measured by the amount by which the carrying value of an asset exceeds the estimated fair value (discounted cash flow) of the asset or asset group. In order to assess the recoverability of the capitalized content development costs, the costs are grouped by program, which is the lowest level of independent cash flows. The Company’s impairment analysis is based upon forecasted financial and operational results. The actual results could vary from the Company’s forecasts, especially in relation to recently launched programs. For the three and nine months ended September 30, 2016 and 2015, no impairment of long-lived assets was deemed to have occurred.

Revenue Recognition and Deferred Revenue

The Company recognizes revenue when all of the following conditions are met: (i) persuasive evidence of an arrangement exists, (ii) rendering of services is complete, (iii) fees are fixed or determinable and (iv) collection of fees is reasonably assured.

The Company primarily derives its revenue from long-term contracts that typically range from 10 to 15 years in length. Under these contracts, the Company enables access to its Platform to its clients and their faculty and students. The Company is entitled to a contractually specified percentage of net program proceeds from its clients. These net program proceeds represent gross proceeds billed by clients to students, less credit card fees and other specified charges the Company has agreed to exclude in certain of its client contracts.

The Company generates substantially all of its revenue from multiple-deliverable contractual arrangements with its clients. Under each of these arrangements, the Company provides (i) access to Online Campus, which serves as a learning platform for its client’s faculty and students and which also enables a comprehensive range of other client functions, (ii) access to operations applications which provide the content management, admissions application processing, customer relationship management, and other functionality necessary to effectively operate the Company’s clients’ programs and (iii) technology-enabled services that support the complete lifecycle of a higher education program, including attracting students, advising prospective students through the admissions application process, providing technical, success coaching and other support, facilitating accessibility to individuals with disabilities, and facilitating in-program field placements.

In order to treat deliverables in a multiple-deliverable contractual arrangement as separate units of accounting, deliverables must have standalone value upon delivery. The technology-enabled services within the Platform are provided primarily in support of programs delivered through Online Campus, and for students of the programs delivered through Online Campus. Accordingly, the Company has determined that no individual deliverable has standalone value upon delivery and, therefore, deliverables within the Company’s multiple-deliverable arrangements do not qualify for treatment as separate units of accounting. Therefore, the Company considers all deliverables to be a single unit of accounting and recognizes revenue from the entire arrangement over the term of the service period.

Advance payments are recorded as deferred revenue until services are delivered or obligations are met, at which time revenue is recognized. Deferred revenue as of a particular balance sheet date represents the excess of amounts received as compared to amounts recognized in revenue in the condensed consolidated statements of operations as of the end of the reporting period, and such amounts are reflected as a current liability on the Company’s condensed consolidated balance sheets.

Stock-Based Compensation

The Company accounts for stock-based compensation awards based on the fair value of the award as of the grant date. For awards subject to service-based vesting conditions, the Company recognizes stock-based compensation expense on a straight-line basis over the awards’ requisite service period, adjusted for estimated forfeitures. For awards subject to both performance and service-based vesting conditions, the Company recognizes stock-based compensation expense using an accelerated recognition method when it is probable that the performance condition will be achieved.

See Note 7 for a summary of assumptions used in calculating the fair value of stock options.

Comprehensive Loss

The Company’s net loss equals comprehensive loss for all periods presented as the Company has no material components of other comprehensive income.

Recent Accounting Pronouncements

In August 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The ASU addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice surrounding how certain transactions are classified in the statement of cash flows. The amendments in this ASU are effective for annual reporting periods beginning after December 15, 2017. The Company is currently evaluating the effect that this standard will have on its consolidated statements of cash flows and related disclosures.

In March 2016, the FASB issued ASU No. 2016-09, Compensation —Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The ASU simplifies various aspects related to the accounting and presentation of share-based payments. The guidance also allows employers to withhold shares to satisfy minimum statutory withholding requirements up to the employees’ maximum individual tax rate without causing the award to be classified as a liability. Additionally, the guidance stipulates that cash paid by an employer to a taxing authority when directly withholding shares for tax withholding purposes should be classified as a financing activity on the statement of cash flows, and allows companies to elect an accounting policy to either estimate the share-based award forfeitures (and expense) or account for forfeitures (and expense) as they occur. The amendments in this ASU are effective for fiscal years beginning after December 15, 2016. Early adoption is permitted in any interim or annual period, with any adjustments reflected as of the beginning of the fiscal year of adoption. The Company is currently evaluating the effect that this standard will have on its consolidated financial position and related disclosures.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The ASU introduces a model for lessees requiring most leases to be reported on the balance sheet. Lessor accounting remains substantially similar to current U.S. GAAP. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018. The Company is currently evaluating the effect that this standard will have on its consolidated financial position and related disclosures.

In November 2015, the FASB issued ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. The ASU eliminates the requirement to classify deferred tax assets and liabilities between current and noncurrent. The ASU requires classification of all deferred tax asset and liability balances as noncurrent. The amendments in this ASU are effective for fiscal years beginning after December 15, 2016, with early adoption permitted. Adoption of the ASU is either retrospective to each prior period presented, or prospective. As of December 31, 2015, the Company early adopted the ASU prospectively. Adoption of this standard did not have a material impact on the Company’s consolidated financial position and related disclosures.

In April 2015, the FASB issued ASU No. 2015-05, Intangibles — Goodwill and Other — Internal-Use Software (Subtopic 350-40). The ASU provides guidance to customers in a cloud computing arrangement to determine whether the arrangement includes a software license. When a cloud computing arrangement includes a software license, the customer is required to account for the license element of the arrangement consistent with the acquisition of other software licenses. The amendments in this ASU are effective for fiscal years beginning after December 15, 2015. The Company adopted this ASU on January 1, 2016. Adoption of this standard did not have a material impact on the Company’s consolidated financial position and related disclosures.

In April 2015, the FASB issued ASU No. 2015-03, Interest — Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. The ASU simplifies the presentation of debt issuance costs by requiring that such costs be presented in the consolidated balance sheets as a direct deduction from the carrying value of the associated debt instrument, consistent with debt discounts. Subsequent to the issuance of this ASU, the SEC staff announced that the presentation of debt issuance costs associated with line-of-credit arrangements may be presented as an asset. This announcement was codified by the FASB in ASU 2015-15. The amendments in these ASUs are effective for fiscal years beginning after December 15, 2015. The Company adopted this ASU on January 1, 2016. Adoption of this standard did not have a material impact on the Company’s consolidated financial position and related disclosures.

In January 2015, the FASB issued ASU No. 2015-01, Income Statement — Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items. The ASU simplifies income statement presentation by eliminating the concept of extraordinary items. The amendments in this ASU are effective for fiscal periods beginning after December 15, 2015. The Company adopted this ASU on January 1, 2016. Adoption of this standard did not have a material impact on the Company’s consolidated financial position and related disclosures.

In August 2014, the 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. The ASU requires that an entity’s management evaluate whether there are conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued. The amendments in this ASU are effective for annual reporting periods ending after December 15, 2016. The Company does not expect the new standard to have a significant impact on its reporting process.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), 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. In July 2015, the FASB deferred the mandatory effective date of this ASU by one year from January 1, 2017 to January 1, 2018. Early application is permitted, but not prior to the original effective date of January 1, 2017. Subsequently, the FASB has issued the following standards related to ASU No. 2014-09: ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations; ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing; and ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients. The Company must adopt ASU No. 2016-08, ASU No. 2016-10 and ASU 2016-12 with ASU 2014-09 (collectively, the “new revenue standards”). The new revenue standards may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of adoption. The Company is currently evaluating the effect that the new standards will have on its consolidated financial position and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the new standards on its ongoing financial reporting.
