Accounting Policies [Abstract] |
Principles of Consolidation & Basis of Presentation | a. Principles of Consolidation and Basis of Presentation These consolidated financial statements include the accounts of CEC and our wholly-owned subsidiaries (collectively “CEC”). All inter-company transactions and balances have been eliminated. The results of operations of all acquired businesses have been consolidated for all periods subsequent to the date of acquisition.
Reclassifications | b. Reclassifications During 2013, we completed the sale of our International Segment (see Note 3 “Dispositions” of the notes to our consolidated financial statements for further discussion). Accordingly, the results of operations for our International Segment are reported within discontinued operations. Our remaining six reporting segments are: CTU, AIU (comprises University Schools); Health Education, Culinary Arts, Design & Technology (comprises Career Schools); and Transitional Schools (see Note 18 “Segment Reporting” for additional information). During 2013, we announced the teach-out of six additional campuses, including four campuses within Health Education and two campuses within Design & Technology. These campuses, which employ a gradual teach-out process and no longer enroll new students, are now included within the Transitional Schools segment. As schools within Transitional Schools complete their teach-out and cease operations, the results of operations for all periods presented will be reflected within discontinued operations. During 2013 we completed the teach-out of four campuses, SBC Hazelwood, SBI Landover, SBC Milwaukee and IADT Schaumburg; accordingly, the results of operations for these schools are now reported within discontinued operations. All prior period results have been recast to reflect our reporting segments on a comparable basis.
Management's Use of Estimates | c. Management’s Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles in the U.S. (“GAAP”) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities as of the date of the financial statements and reported amounts of revenues and expenses during the reported period. Significant estimates, among others, include the allowance for doubtful accounts, the allocation of purchase price to the fair value of net assets and liabilities acquired in connection with business combinations, the assumptions surrounding sublease income utilized in determining the fair value of remaining lease obligations, assumptions utilized in calculating income tax related matters including our deferred tax balances and any respective valuation allowance, fair values used in asset impairment evaluations including goodwill, intangible assets and long-lived assets, and the assumptions used in determining the fair value of accruals for severance and related costs. Although these estimates are based upon management’s best knowledge of current events and actions that we may undertake in the future, actual results could differ from these estimates.
Concentration of Credit Risk | d. Concentration of Credit Risk A substantial portion of credit extended to students is repaid through the students’ participation in various federal financial aid programs authorized by Title IV of the Higher Education Act of 1965, as amended (“HEA”), which we refer to as “Title IV Programs.” For the years ended December 31, 2013, 2012 and 2011, approximately 78%, 80% and 83% respectively, of our schools’ cash receipts from tuition payments came from Title IV Program funding. Transfers of funds received from Title IV Programs are made in accordance with the U.S. Department of Education’s (“ED”) requirements. Changes in ED funding of Title IV Programs could have a material impact on our ability to attract students and the realizability of our student receivables. See Item 1A, “Risk Factors,” for further discussion of the risks associated with Title IV Programs.
Allowance for Doubtful Accounts | e. Allowance for Doubtful Accounts We extend unsecured credit to a portion of the students who are enrolled at our schools for tuition and certain other educational costs. Based upon past experience and judgment, we establish an allowance for doubtful accounts with respect to student receivables which we estimate will ultimately not be collectible. As such, our results from operations only reflect the amount of revenue that is estimated to be reasonably collectible. Our standard allowance estimation methodology considers a number of factors that, based on our collections experience, we believe have an impact on our credit risk and the realizability of our student receivables. Among these factors are a student’s status (in-school or out-of-school), anticipated funding source (third party, internal short-term and extended payment plans), whether or not an out-of-school student has completed his or her program of study, and our overall collections history. Out-of-school students include students who have withdrawn from or completed their programs of study. All other students are classified as in-school students. We monitor our collections and write-off experience to assess whether or not adjustments to our allowance percentage estimates are necessary. Changes in trends in any of the factors that we believe impact the realizability of our student receivables, as noted above, or modifications to our credit standards, collection practices, and other related policies may impact our estimate of our allowance for doubtful accounts and our results from operations. Additionally, we monitor certain internal and external factors, including changes in our academic programs, as well as changes in the current economic, legislative and regulatory environments.
Fair Value of Financial Instruments | f. Fair Value of Financial Instruments The carrying amounts for cash and cash equivalents, short-term investments, current portion of accounts receivables and accounts payable reported in our consolidated balance sheets approximate fair value because of the nature of these financial instruments, as they generally have short maturity periods. The fair value measure of accounting for financial instruments establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. Our investment in auction rate securities (“ARS”) is presented within other non-current assets on the consolidated balance sheets. As of December 31, 2013, we have determined this investment is at risk for impairment due to the nature of the liquidity of the market over the past year. We believe this impairment is temporary, as we do not intend to sell the investment and it is unlikely we will be required to sell the investment before recovery of its amortized cost basis. Our student receivables with repayment periods greater than one year are presented within non-current assets on the consolidated balance sheets. It is not practicable to estimate the fair value of these financial instruments, since observable market data is not readily available, and no reasonable estimation methodology exists.
Revenue Recognition | g. Revenue Recognition Our revenue, which is derived primarily from academic programs taught to students who attend our schools, is generally segregated into two categories: (1) tuition and registration fees and (2) other. Tuition and registration fees represent costs to our students for educational services provided by our schools. For certain schools, we bill students a one-time registration fee at the beginning of their program and recognize the registration fee revenue on a straight-line basis over that program period, which includes any applicable externship period. Our schools charge tuition at varying amounts, depending on the school, the type of program and specific curriculum. A majority of our schools bill students a single charge that covers tuition and required program materials, such as textbooks and supplies, which we treat as a single accounting unit. Generally, we bill student tuition fees, including those treated as a single accounting unit, at the beginning of each academic period, and recognize the tuition fees as revenue on a straight-line basis over either the academic term or program period, which includes any applicable externship period. The tuition fees earnings method is determined by the type of program a student is enrolled in. Typically, schools that offer our culinary arts and our health programs earn tuition fees over the entire program while the remainder of our schools earns tuition fees over each academic term. The portion of tuition and registration fee payments received from students but not yet earned is recorded as deferred tuition revenue and reported as a current liability on our consolidated balance sheets, as we expect to earn these revenues within the next year. Deferred tuition revenue is stated net of outstanding student receivables on a student-by-student basis as of the end of the reporting period. If a student withdraws from one of our schools prior to the completion of the academic term or program period, we refund the portion of tuition and registration fees already paid that, pursuant to our refund policy and applicable federal and state law and accrediting agency standards, we are not entitled to retain. Generally, the amount to be refunded to a student is calculated based upon the period of time the student has attended classes and the amount of tuition and registration fees paid by the student as of their withdrawal date. These refunds typically reduce deferred tuition revenue and cash on our consolidated balance sheets as we generally do not recognize tuition revenue in our consolidated statements of (loss) income and comprehensive (loss) income until the related refund provisions have lapsed. The portion of deferred revenue we are entitled to retain once a student withdraws is immediately recognized as revenue with a corresponding charge to bad debt expense for any amount deemed to be uncollectible. Our schools’ academic year is generally at least 30 weeks in length but varies both by school and program of study and is divided by academic terms or payment periods. Academic terms or payment periods are determined by regulatory requirements mandated by the federal government and/or appropriate accrediting body, which also vary by school and program. Academic terms are determined by start dates, which also vary by school and program. Our students finance costs through a variety of funding sources, including, among others, federal loan and grant programs, school payment plans, private loans and grants, private and institutional scholarships and cash payments. Other revenue, which consists primarily of bookstore sales for schools not using single-charge billing and contract-training revenue, is billed and recognized as goods are delivered or services are performed.
Cash and Cash Equivalents | h. Cash and Cash Equivalents Cash equivalents include short-term investments with a term to maturity of less than 90 days at the date of purchase. Loans which are disbursed under our current Credit Agreement are secured by 100% cash collateral. The Company has funds which are restricted in use and provide collateral for letters of credit. See Note 12 “Credit Agreements” for further details of our current amended and restated credit agreement and the original credit agreement.
Student Receivables | i. Student Receivables Student receivables represent funds owed to us in exchange for the education services that we provided to a student. Student receivables are reported net of an allowance for doubtful accounts and net of deferred tuition revenue, as determined on a student-by-student basis as of the end of the reporting period. Student receivables which are due to be paid in less than one year are recorded as current assets within our consolidated balance sheets. Student receivables which are due to be paid at dates ranging from one to six years from the balance sheet date are reported as non-current assets within our consolidated balance sheets. Generally, a student receivable balance is written off once it reaches greater than 90 days past due. Although we analyze past due receivables, it is not practical to provide an aging of our non-current student receivable balances as a result of the methodology utilized in determining our earned student receivable balances. Student receivables are recognized on our consolidated balance sheets as they are deemed earned over the course of a student’s program and/or term, and therefore cash collections are not applied against specifically dated transactions.
Discontinued Operations | Discontinued Operations Discontinued operations are accounted for in accordance with the provisions of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Section 360-10-35 Property, Plant, and Equipment. In accordance with FASB ASC Section 360-10-35, the net assets of discontinued operations are recorded on our consolidated balance sheets at estimated fair value. The results of operations of discontinued operations are segregated from continuing operations and reported separately as discontinued operations in our consolidated statements of (loss) income and comprehensive (loss) income. See Note 5 “Discontinued Operations” of the notes to our consolidated financial statements for further discussion.
Investments | k. Investments Our investments, which primarily consist of U.S. Treasury bills, are classified as “available-for-sale” and recorded at fair value. Any unrealized holding gains or temporary unrealized holding losses, net of income tax effects, are reported as a component of accumulated other comprehensive loss within stockholders’ equity. Realized gains and losses are computed on the basis of specific identification and are included in miscellaneous income (expense) in our consolidated statements of (loss) income and comprehensive (loss) income. Our investment in a municipal auction rate security has a stated term to maturity of greater than one year. As such, we classify this investment as non-current on our consolidated balance sheets within other assets.
Inventories | l. Inventories Inventories, consisting principally of program materials, textbooks, food, and supplies, are stated at the lower of cost, determined on a first-in, first-out basis, or market. The cost of inventory is reflected as a component of educational services and facilities expense as the items are used or sold.
Property and Equipment | m. Property and Equipment Property and equipment are stated at cost less accumulated depreciation. Depreciation and amortization are recognized using the straight-line method over the estimated useful lives of the related assets for financial reporting purposes and an accelerated method for income tax reporting purposes. Leasehold improvements and assets recorded under capital leases are amortized on a straight-line basis over the shorter of the life of the lease or the useful life. Maintenance, repairs, minor renewals, and betterments are expensed as incurred, and major improvements, which extend the useful life of the asset, are capitalized.
Goodwill and Intangible Assets | n. Goodwill and Intangible Assets Goodwill represents the excess of cost over fair market value of identifiable net assets acquired through business purchases. In accordance with FASB ASC Topic 350 – Intangibles-Goodwill and Other, we review goodwill for impairment on at least an annual basis by applying a fair-value-based test. In evaluating the recoverability of the carrying value of goodwill, we must make assumptions regarding the fair value of our reporting units, as defined under FASB ASC Topic 350. Goodwill is evaluated using a two-step impairment test at the reporting unit level. A reporting unit can be a strategic business unit or business within a strategic business unit. The first step compares the book value of a reporting unit, including goodwill, with its fair value, as determined by a combination of income and market approach valuation methodologies. If the book value of a reporting unit exceeds its fair value, we complete the second step to determine the amount of goodwill impairment loss that we should record. In the second step, we determine an implied fair value of the reporting unit’s goodwill by allocating the fair value of the reporting unit to all of the assets and liabilities other than goodwill (including any unrecognized intangible assets). The amount of impairment loss is equal to the excess of the book value of the goodwill over the implied fair value of goodwill. In performing our annual review of goodwill balances for impairment, we estimate the fair value of each of our reporting units based on projected future operating results and cash flows, market assumptions and comparative market multiple methods. Determining fair value requires significant estimates and assumptions based on an evaluation of a number of factors, such as marketplace participants, relative market share, new student interest, student retention, future expansion or contraction expectations, amount and timing of future cash flows and the discount rate applied to the cash flows. Projected future operating results and cash flows used for valuation purposes do reflect improvements relative to recent historical periods with respect to, among other things, revenue growth and operating margins. Although we believe our projected future operating results and cash flows and related estimates regarding fair values are based on reasonable assumptions, historically projected operating results and cash flows have not always been achieved. The failure of one of our reporting units to achieve projected operating results and cash flows in the near term or long term may reduce the estimated fair value of the reporting unit below its carrying value and result in the recognition of a goodwill impairment charge. Significant management judgment is necessary to evaluate the impact of operating and macroeconomic changes and to estimate future cash flows. Assumptions used in our impairment evaluations, such as forecasted growth rates and our cost of capital, are based on the best available market information and are consistent with our internal forecasts and operating plans. In addition to cash flow estimates, our valuations are sensitive to the rate used to discount cash flows and future growth assumptions. These assumptions could be adversely impacted by certain of the risks discussed in “Risk Factors” in Item 1A. Intangible assets include both indefinite and definite-lived assets. Indefinite-lived assets include our trade names and accreditation rights, which are recorded at fair market value upon acquisition and subsequently reviewed on an annual basis for impairment. Accreditation rights represent the ability of our schools to participate in Title IV Programs. Our definite-lived assets include courseware, which represents the value of acquired curriculum, including lesson plans and syllabi, used to deliver educational services. Acquired courseware balances are amortized on a straight-line basis over their useful lives, which are estimated by management based upon, among other things, the expected future utilization period and the nature of the related academic programs. Other definite-lived intangible assets represent ownership related to renewable internet domain names and are amortized on a straight-line basis over the applicable renewal periods. See Note 10 “Goodwill and Other Intangible Assets” of the notes to our consolidated financial statements for further discussion.
Impairment of Long-Lived Assets | o. Impairment of Long-Lived Assets We review property and equipment, definite-lived intangible assets, and other long-lived assets for impairment on an annual basis or whenever adverse events or changes in circumstances indicate that the carrying amounts of such assets may not be recoverable. If such adverse events or changes in circumstances occur, we will recognize an impairment loss if the undiscounted future cash flows expected to be generated by the assets are less than the carrying value of the related assets. The impairment loss would reduce the carrying value of the assets to their estimated fair value. See Note 8 “Property and Equipment” of the notes to our consolidated financial statements for further discussion.
Contingencies | p. Contingencies During the ordinary course of business, we are subject to various claims and contingencies. In accordance with FASB ASC Topic 450 – Contingencies, when we become aware of a claim or potential claim, we assess the likelihood of any related loss or exposure. The probability of whether an asset has been impaired or a liability has been incurred, and whether the amount of loss can be reasonably estimated, is analyzed, and if the loss contingency is both probable and reasonably estimable, then we accrue for costs, including direct costs incurred, associated with the loss contingency. If no accrual is made but the loss contingency is reasonably possible, we disclose the nature of the contingency and the related estimate of possible loss or range of loss if such an estimate can be made. For all matters that are currently being reviewed, we expense legal fees, including defense costs, as they are incurred. Loss contingencies include, but are not limited to, possible losses related to legal proceedings and regulatory compliance matters, and our assessment of exposure requires subjective and judgmental assessment. Liabilities established to provide for contingencies are adjusted as further information develops, circumstances change, or contingencies are resolved. See Note 13 “Commitments and Contingencies” of the notes to our consolidated financial statements for additional information.
Income Taxes | q. Income Taxes We are subject to the income tax laws of the U.S. and various state, local and foreign jurisdictions. These tax laws are complex and subject to interpretation. As a result, significant judgments and interpretations are required in determining our income tax (benefits) provisions and evaluating our uncertain tax positions. We account for income taxes in accordance with FASB ASC Topic 740 – Income Taxes. Topic 740 requires the recognition of deferred income tax assets and liabilities based upon the income tax consequences of temporary differences between financial reporting and income tax reporting by applying enacted statutory income tax rates applicable to future years to differences between the financial statement carrying amounts and the income tax basis of existing assets and liabilities. Topic 740 also requires that deferred income tax assets be reduced by a valuation allowance if it is more likely than not that some portion of the deferred income tax asset will not be realized. In assessing the need for a valuation allowance, we consider both positive and negative evidence related to the likelihood of realization of the deferred tax assets. Topic 740 provides that important factors in determining whether a deferred tax asset will be realized are whether there has been sufficient taxable income in recent years and whether sufficient taxable income is expected in future years in order to utilize the deferred tax asset. In evaluating the realizability of deferred income tax assets, we consider, among other things, historical levels of taxable income along with possible sources of future taxable income, which include: the expected timing of the reversals of existing temporary reporting differences, the existence of taxable income in prior carryback year(s), the expected impact of tax planning strategies that may be implemented to prevent the potential loss of future income tax benefits and expected future taxable income. Changes in, among other things, income tax legislation, statutory income tax rates, or future taxable income levels could materially impact our valuation of income tax assets and liabilities and could cause our income tax provision to vary significantly among financial reporting periods. If, based on the weight of available evidence, it is more likely than not the deferred tax assets will not be realized, with placing less weight on projections for future growth as projections for future growth are less objectively verifiable, we record a valuation allowance. The weight given to the positive and negative evidence is commensurate with the extent to which the evidence may be objectively verified. A high degree of judgment is required to determine if, and the extent to which, valuation allowances should be recorded against deferred tax assets. A significant piece of objective negative evidence evaluated is the cumulative loss incurred over the three-year period ended December 31, 2013. Such objective evidence limits the ability to consider other subjective evidence such as our projections for future growth as projections for future growth are less objectively verifiable. Topic 740 further clarifies the accounting for uncertainty in income taxes recognized in an entity’s financial statements and prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in an income tax return. Topic 740 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition.
Deferred Rent Obligations | r. Deferred Rent Obligations Certain of the real estate operating lease agreements to which we are party contain rent escalation clauses or lease incentives, such as rent abatements or tenant improvement allowances. Rent escalation clauses and lease incentives are taken into account in determining total rent expense to be recognized during the term of the lease, which begins on the date that we take control of the leased space. Renewal options are considered when evaluating the overall term of the lease. In accordance with FASB ASC Topic 840 – Leases, differences between periodic rent expense and periodic cash rental payments, caused primarily by the recognition of rent expense on a straight-line basis and tenant improvement allowances due or received from lessors, are recorded as deferred rent obligations on our consolidated balance sheets. We record tenant improvement allowances as a deferred rent obligation on our consolidated balance sheets and as a cash inflow from operating activities in our consolidated statements of cash flows. We record capital expenditures funded by tenant improvement allowances received as a leasehold improvement on our consolidated balance sheets and as an investing activity within our consolidated statements of cash flows.
Share-Based Compensation | s. Share-Based Compensation FASB ASC Topic 718 – Compensation-Stock Compensation requires that all share-based payments to employees and non-employee directors, including grants of stock options, shares or units of restricted stock, and the compensatory elements of employee stock purchase plans, be recognized in the financial statements based on the estimated fair value of the equity or liability instruments issued. See Note 15 “Share-Based Compensation” of the notes to our consolidated financial statements for further discussion of our share-based compensation plans, the nature of share-based awards issued under the plans and our accounting for share-based awards.
Foreign Currency Translation | t. Foreign Currency Translation As of December 3, 2013, we sold and transferred control of our International Segment. For the years ended December 31, 2013, 2012 and 2011, revenues and expenses related to our foreign-based subsidiaries have been translated into U.S. dollars using average exchange rates during the reporting period, with transaction gains or losses included in net (loss) income. The aggregate transaction gains or losses included in net (loss) income for the years ended December 31, 2012 and 2011 were not significant. During 2013, we reclassified $10.0 million of cumulative translation adjustments from our International schools and AIU London as part of the gain (loss) on sale of those operations in accordance with FASB ASC Topic 810 – Consolidation. The assets and liabilities of our International subsidiaries remaining as of each balance sheet date have been translated into U.S. dollars using exchange rates in effect at the balance sheet dates, with gains and losses resulting from such translations included in accumulated other comprehensive loss. Accumulated other comprehensive loss included a comprehensive loss related to foreign currency translations of less than $0.1 million for the year ended December 31, 2013 and $4.3 million for the year ended December 31, 2012. The functional currency of each of our foreign subsidiaries is its local currency. See Note 3 “Dispositions” of the notes to our consolidated financial statements for additional information.
Educational Services and Facilities Expense | u. Educational Services and Facilities Expense Educational services and facilities expense includes costs directly attributable to the educational activities of our schools, including: (1) salaries and benefits of faculty, academic administrators, and student support personnel, (2) costs of educational supplies and facilities, including rents on school leases, certain costs of establishing and maintaining computer laboratories, costs of student housing, and owned and leased facility costs, and (3) costs of other goods and services provided by our schools, including costs of textbooks, laptop computers, restaurant services and contract training. Costs of such other goods and services for continuing operations, included in educational services and facilities expense in our consolidated statements of (loss) income and comprehensive (loss) income, were approximately $39.7 million, $55.8 million and $79.9 million for the years ended December 31, 2013, 2012 and 2011, respectively.
Advertising Costs | v. Advertising Costs Advertising costs are expensed as incurred. Advertising costs for continuing operations, which are included in general and administrative expenses in our consolidated statements of (loss) income and comprehensive (loss) income, were $272.0 million, $302.0 million and $276.3 million, for the years ended December 31, 2013, 2012 and 2011, respectively.
Fair Value Measurements | Fair Value Measurements FASB ASC Topic 820 – Fair Value Measurements establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.
