Accounting Policies [Abstract] |
Principles of Consolidation | Principles of Consolidation The consolidated financial statements include the accounts of Grand Canyon Education, Inc. and its wholly owned subsidiaries. Intercompany transactions have been eliminated in consolidation
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.
Cash and Cash Equivalents | Cash and Cash Equivalents The University invests a portion of its cash in excess of current operating requirements in short term certificates of deposit and money market instruments. The University considers all highly liquid investments with maturities of three months or less at the time of purchase to be cash equivalents.
Restricted Cash and Cash Equivalents | Restricted Cash and Cash Equivalents A significant portion of the University’s revenue is received from students who participate in government financial aid assistance programs. Restricted cash and cash equivalents primarily represent amounts received from the federal and state governments under various student aid grant and loan programs, such as Title IV. The University receives these funds subsequent to the completion of the authorization and disbursement process and holds them for the benefit of the student. The U.S. Department of Education (“Department of Education”) requires Title IV funds collected in advance of student billings to be restricted until the course begins. The University records all of these amounts as a current asset in restricted cash and cash equivalents. The majority of these funds remain as restricted for an average of 60 to 90 days from the date of receipt.
Investments | Investments The University considers its investments in municipal bond, mutual funds, municipal securities and certificates of deposit as available-for-sale securities. Available-for-sale securities are carried at fair value, determined using Level 1 and Level 2 of the hierarchy of valuation inputs, with the use of quoted market prices and inputs other than quoted prices that are observable for the assets, with unrealized gains and losses, net of tax, reported as a separate component of other comprehensive income. Unrealized losses considered to be other-than-temporary are recognized currently in earnings. Amortization of premiums, accretion of discounts, interest and dividend income and realized gains and losses are included in interest and other income.
Property and Equipment | Property and Equipment Property and equipment are recorded at cost less accumulated depreciation. Depreciation is computed using the straight-line method. Normal repairs and maintenance are expensed as incurred. Expenditures that materially extend the useful life of an asset are capitalized. Construction in progress represents items not yet placed in service and are not depreciated. Internally developed software represents qualifying salary and consulting costs for time spent on developing internal use software and is included in construction in progress until its completion. The University capitalizes interest using its interest rates on the specific borrowings used to finance the improvements, which approximated 2.8% in 2017, 2.2% in 2016, and 1.9% in 2015. Interest cost capitalized and incurred in the years ended December 31, 2017, 2016, and 2015 are as follows:
|  | Year Ended December 31, |
|  | 2017 |  |  | 2016 |  |  | 2015 |
Interest incurred |  | $ | 2,656 |  |  | $ | 2,538 |  |  | $ | 1,962 |
Interest capitalized |  |  | 487 |  |  |  | 1,210 |  |  |  | 714 |
Interest expense |  | $ | 2,169 |  |  | $ | 1,328 |  |  | $ | 1,248 |
Depreciation is provided using the straight-line method over the estimated useful lives of the assets. Furniture and fixtures, computer equipment, and vehicles generally have estimated useful lives of ten, four, and five years, respectively. Leasehold improvements are depreciated over the shorter of their lease term or their useful life. Land improvements and buildings are depreciated over lives ranging from 10 to 40 years.
Leases | Leases The University enters into various lease agreements in conducting its business. At the inception of each lease, the University evaluates the lease agreement to determine whether the lease is an operating or capital lease. In addition, many of the lease agreements contain renewal options and tenant improvement allowances. When such items are included in a lease agreement, the University records a deferred liability on the balance sheet and records the rent expense evenly over the term of the lease. Leasehold improvements are included as investing activities and are included as additions to property, plant and equipment. For leases with renewal options, the University records rent expense and amortizes the leasehold improvement on a straight-line basis over the initial non-cancelable lease term unless it intends to exercise the renewal option. Once it extends the renewal option, the University amortizes any tenant improvement allowances over the extended lease period as well as the leasehold improvement asset (unless the extended lease term is longer than the economic life of the asset). The University expenses any additional payments under its operating leases for taxes, insurance or other operating expenses as incurred. Lease termination costs In July 2016, the University notified a current landlord of its intent to vacate leased space by the end of the fourth quarter of 2016. As part of that notification, the University was required to pay a termination fee to its landlord of $3,363 which was recorded as an expense in the third quarter of 2016. As of December 31, 2016, the University had vacated the space, and expensed an additional $160 in the fourth quarter of 2016 related to the remaining amounts due under the lease net of remaining deferred rent.
Other Assets | Other Assets The University developed our online delivery platform with an affiliated entity and put this platform into full production in 2011. The University has prepaid perpetual license fees and source code rights for the software developed, and has prepaid maintenance and service fees. Included in current other assets is the amount that will be amortized in the next twelve month cycle for maintenance and service fees and included in property and equipment is the amount that will be amortized over fifteen years for the perpetual licenses.
Long-Lived Assets | Long-Lived Assets The University evaluates the recoverability of its long-lived assets for impairment, other than goodwill, whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to undiscounted future net cash flows expected to be generated by the assets. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets.
Prepaid Royalties | Prepaid Royalties In connection with the February 2004 acquisition of the assets of Grand Canyon University from a non-profit foundation, the University entered into a royalty fee arrangement with the former owner in which the University agreed to pay a stated percentage of cash revenue generated by its online programs. The University settled all future royalty obligations with the former owner in April 2008 when it finalized an agreement to pay $22,500 to the former owner. Of this payment $5,920 was considered as settlement of the future royalty payment obligation and is included in the accompanying balance sheet as a component of “Prepaid Royalty” and is being amortized over a period of 20 years.
Goodwill | Goodwill Goodwill represents the excess of the cost over the fair market value of net assets acquired, including identified intangible assets. Goodwill is tested annually or more frequently if circumstances indicate potential impairment. The Financial Accounting Standards Board (“FASB”) has issued guidance that permits an entity to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test. The University performed its annual goodwill impairment test, by performing a qualitative assessment. Following this assessment, the University determined that it is more likely than not that its fair value exceeds its carrying amount.
Share-Based Compensation | Share-Based Compensation The University measures and recognizes compensation expense for share-based payment awards made to employees and directors. The fair value of the University’s restricted stock awards is based on the market price of its common stock on the date of grant. Stock-based compensation expense related to restricted stock grants is expensed over the vesting period using the straight-line method for University employees and the University’s board of directors. Starting January 1, 2017 with the adoption of the share-based compensation accounting standard, the University made an accounting policy election to account for forfeitures as they occur, prior to 2017 these forfeitures were estimated and reported net of the expense. See Note 2, Accounting Pronouncements Adopted in 2017.
Derivatives and Hedging | Derivatives and Hedging Derivative financial instruments are recorded on the balance sheet as assets or liabilities and re-measured at fair value at each reporting date. For derivatives designated as cash flow hedges, the effective portion of the gain or loss on the derivative is reported as a component of other comprehensive income and reclassified into earnings in the same period or period during which the hedged transaction affects earnings. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings. Derivative financial instruments enable the University to manage its exposure to interest rate risk. The University does not engage in any derivative instrument trading activity. Credit risk associated with the University’s derivatives is limited to the risk that a derivative counterparty will not perform in accordance with the terms of the contract. Exposure to counterparty credit risk is considered low because these agreements have been entered into with institutions with Aa or higher credit ratings, and they are expected to perform fully under the terms of the agreements.
Fair Value of Financial Instruments | Fair Value of Financial Instruments The carrying value of cash and cash equivalents, accounts receivable, note receivable, accounts payable, accrued compensation and benefits and accrued liabilities approximate their fair value based on the liquidity or the short-term maturities of these instruments. The carrying value of notes payable approximate fair value based on its variable rate index. The carrying value of notes payable approximate fair value based upon market interest rates available to the University for debt of similar risk and maturities. Derivative financial instruments are carried at fair value, determined using Level 2 of the hierarchy of valuation inputs as defined in the FASB Accounting Standards Codification (“Codification”), with the use of inputs other than quoted prices that are observable for the asset or liability. See Note 8, Derivative Instruments. The fair value of investments, primarily municipal securities, were determined using Level 2 of the hierarchy of valuation inputs, with the use of inputs other than quoted prices that are observable for the assets. The unit of account used for valuation is the individual underlying security. The municipal securities are comprised of city and county bonds related to schools, water and sewer, utilities, transportation, healthcare and housing.
Income Taxes | Income Taxes The University accounts for income taxes payable or refundable for the current year and deferred tax assets and liabilities for future tax consequences of events that have been recognized in the University’s consolidated financial statements or tax returns. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which the temporary differences are expected to be realized. The University applies a more-likely-than-not threshold for financial statement recognition and measurement of an uncertain tax position taken or expected to be taken in a tax return. The University recognizes interest and penalties related to uncertain tax positions in income tax expense. As of December 31, 2017 and 2016, the University has reserved approximately $2,008 and $1,981, respectively, for uncertain tax positions, including interest and penalties, which is classified within accrued liabilities on the accompanying consolidated balance sheet. The University has deferred tax assets, which are subject to periodic recoverability assessments. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount that more likely than not will be realized. Realization of the deferred tax assets is principally dependent upon achievement of projected future taxable income.
Commitments and Contingencies | Commitments and Contingencies The University accrues for a contingent obligation when it is probable that a liability has been incurred and the amount is reasonably estimable. When the University becomes aware of a claim or potential claim, the likelihood of any loss exposure is assessed. If it is probable that a loss will result and the amount of the loss is estimable, the University records a liability for the estimated loss. If the loss is not probable or the amount of the potential loss is not estimable, the University will disclose the claim if the likelihood of a potential loss is reasonably possible and the amount of the potential loss could be material. Estimates that are particularly sensitive to future changes include tax, legal, and other regulatory matters, which are subject to change as events evolve, and as additional information becomes available during the administrative and litigation process. The University expenses legal fees as incurred.
Revenue Recognition | Revenue Recognition Net revenues consist primarily of tuition and fees derived from courses taught by the University online, at its over 275 acre campus in Phoenix, Arizona, and at facilities it leases or those of employers, as well as from related educational resources that the University provides to its students, such as access to online materials. Tuition revenue and most fees from related educational resources are recognized pro-rata over the applicable period of instruction, net of scholarships provided by the University. For the years ended December 31, 2017, 2016 and 2015, the University’s revenue was reduced by approximately $196,334, $179,230 and $163,893, respectively, as a result of scholarships that the University offered to students. The University maintains an institutional tuition refund policy, which provides for all or a portion of tuition to be refunded if a student withdraws during stated refund periods. Certain states in which students reside impose separate, mandatory refund policies, which override the University’s policy to the extent in conflict. If a student withdraws at a time when only a portion, or none of the tuition is refundable, then in accordance with its revenue recognition policy, the University continues to recognize the tuition that was not refunded pro-rata over the applicable period of instruction. However, for students that have taken out financial aid to pay their tuition and for which a return to Title IV is required as a result of his or her withdrawal, the University recognizes revenue after a student withdraws only at the time of cash collection. Sales tax collected from students is excluded from net revenues. Collected but unremitted sales tax is included as an accrued liability in our consolidated balance sheet. The University also charges online students an upfront learning management fee, which is deferred and recognized over the average expected term of a student. Costs that are direct and incremental to new online students are also deferred and recognized ratably over the average expected term of a student. Deferred revenue and student deposits in any period represent the excess of tuition, fees, and other student payments received as compared to amounts recognized as revenue on the consolidated income statement and are reflected as current liabilities in the accompanying consolidated balance sheets. The University’s educational programs have starting and ending dates that differ from its fiscal quarters. Therefore, at the end of each fiscal quarter, a portion of revenue from these programs is not yet earned. Other revenues may be recognized as sales occur or services are performed.
Allowance for Doubtful Accounts | Allowance for Doubtful Accounts The University records an allowance for doubtful accounts for estimated losses resulting from the inability, failure or refusal of its students to make required payments, which includes the recovery of financial aid funds advanced to a student for amounts in excess of the student’s cost of tuition and related fees. The University determines the adequacy of its allowance for doubtful accounts based on an analysis of its historical bad debt experience, current economic trends, and the aging of the accounts receivable and student status. The University applies reserves to its receivables based upon an estimate of the risk presented by the age of the receivables and student status. The University writes off accounts receivable balances of active students at the earlier of the time the balances were deemed uncollectible, or one year after the revenue is generated. The University accelerates the write off of inactive student accounts such that the accounts are written off by day 150. The University reflects accounts receivable with an offsetting allowance as long as management believes there is a reasonable possibility of collection. Bad debt expense is recorded as an instructional costs and services expense in the consolidated income statement.
Instructional Costs and Services | Instructional Costs and Services Instructional costs and services consist primarily of costs related to the administration and delivery of the University’s educational programs. This expense category includes salaries, benefits and share-based compensation for full-time and adjunct faculty and administrative personnel, information technology costs, bad debt expense, curriculum and new program development costs (which are expensed as incurred) and costs associated with other support groups that provide services directly to the students. This category also includes an allocation of depreciation, amortization, rent, and occupancy costs attributable to the provision of educational services, primarily at the University’s Phoenix, Arizona campus.
Admissions Advisory and Related | Admissions Advisory and Related Admissions advisory and related expenses include salaries and benefits for admissions advisory personnel, and revenue share expense as well as an allocation of depreciation, amortization, rent and occupancy costs attributable to the admissions advisory personnel.
Advertising | Advertising Advertising expenses include brand advertising, marketing leads and other branding activities. Advertising costs are expensed as incurred.
Marketing and Promotional | Marketing and Promotional Marketing and promotional expenses include salaries, benefits and share-based compensation for marketing personnel, and other promotional expenses. This category also includes an allocation of depreciation, amortization, rent, and occupancy costs attributable to marketing and promotional activities. Marketing and promotional costs are expensed as incurred.
General and Administrative | General and Administrative General and administrative expenses include salaries, and benefits and share-based compensation of employees engaged in corporate management, finance, human resources, compliance, and other corporate functions. General and administrative expenses also include an allocation of depreciation, amortization, rent, and occupancy costs attributable to the departments providing general and administrative functions.
Insurance/Self-Insurance | Insurance/Self-Insurance The University uses a combination of insurance and self-insurance for a number of risks, including claims related to employee health care, workers’ compensation, general liability, and business interruption. Liabilities associated with these risks are estimated based on, among other things, historical claims experience, severity factors, and other actuarial assumptions. The University’s loss exposure related to self-insurance is limited by stop loss coverage on a per occurrence and aggregate basis. The University regularly analyzes its reserves for incurred but not reported claims, and for reported but not paid claims related to self-funded insurance programs. While the University believes reserves are adequate, significant judgment is involved in assessing these reserves such as assessing historical paid claims, average lags between the claims’ incurred date, reported dates and paid dates, and the frequency and severity of claims. There may be differences between actual settlement amounts and recorded reserves and any resulting adjustments are included in expense once a probable amount is known.
Concentration of Credit Risk | Concentration of Credit Risk The University believes the credit risk related to cash equivalents and investments is limited due to its adherence to an investment policy that required investments to have a minimum BBB rating, depending on the type of security, by one major rating agency at the time of purchase. All of the University’s cash equivalents and investments as of December 31, 2017 and 2016 consist of investments rated BBB or higher by at least one rating agency. Additionally, the University utilizes more than one financial institution to conduct initial and ongoing credit analysis on its investment portfolio to monitor and lower the potential impact of market risk associated with its cash equivalents and investment portfolio. A majority of the University’s revenues are derived from tuition financed under the Title IV programs of the Higher Education Act of 1965, as amended (the “Higher Education Act”). The financial aid and assistance programs are subject to political and budgetary considerations and are subject to extensive and complex regulations. The University’s administration of these programs is periodically reviewed by various regulatory agencies. Any regulatory violation could be the basis for the initiation of potentially adverse actions including a suspension, limitation, or termination proceeding, which could have a material adverse effect on the University. Students obtain access to federal student financial aid through a Department of Education prescribed application and eligibility certification process. Student financial aid funds are generally made available to students at prescribed intervals throughout their predetermined expected length of study. Students typically apply the funds received from the federal financial aid programs first to pay their tuition and fees. Any remaining funds are distributed directly to the student.
Segment Information | Segment Information The University operates as a single educational delivery operation using a core infrastructure that serves the curriculum and educational delivery needs of both its ground and online students regardless of geography. The University’s Chief Executive Officer manages the University’s operations as a whole and no expense or operating income information is generated or evaluated on any component level.
Accounting Pronouncements Adopted in 2017 | Accounting Pronouncements Adopted in 2017 In March 2016, the FASB issued “Compensation – Stock Compensation: Improvement to Employee Share-Based Payment Accounting,” to simplify certain aspects of the accounting for share-based payment transactions to employees. The new standard requires excess tax benefits and tax deficiencies to be recorded in the consolidated statements of income as a component of the provision for income taxes when stock awards vest or options are exercised. In addition, it eliminates the requirement to reclassify cash flows related to excess tax benefits from operating activities to financing activities on the consolidated statements of cash flows. The standard also provides an accounting policy election to account for forfeitures as they occur, allows us to withhold more of an employee’s vesting shares for tax withholding purposes without triggering liability accounting, and clarifies that all cash payments made to tax authorities on an employee’s behalf for withheld shares should be presented as a financing activity on our consolidated cash flows statement. The University adopted the new guidance in the first quarter of 2017 which required us to reflect any adjustments as of January 1, 2017. Upon adoption, excess tax benefits or deficiencies from share-based awards or options are now reflected in the consolidated statement of income as a component of the provision for income taxes, whereas previously they were recognized in equity. The University elected to account for forfeitures as they occur, rather than estimate expected forfeitures. The net cumulative effect of this change increased additional paid-in capital and decreased retained earnings as of January 1, 2017 by $59, net of tax. The University did not have any previously unrecognized excess tax effects that had not been recorded as a reduction to tax liability. The University adopted the provisions of the standard impacting the cash flow presentation retrospectively, and accordingly, to conform to the current period presentation, we reclassified $9,928 and $3,636 of excess tax benefits which had been included as a financing activity to an operating activity for the years ended December 31, 2016 and 2015, respectively, in our consolidated statement of cash flows. The presentation requirement for cash flows related to employee taxes paid for withheld shares had no impact on our consolidated statement of cash flows since such cash flows have historically been presented as a financing activity. Adoption of the provision of the new standard related to income taxes was adopted prospectively and resulted in a reduction to our provision for income taxes of $16,511 for the year ended December 31, 2017, due to the recognition of excess tax benefits from restricted stock awards that vested or stock options that were exercised in 2017. Our restricted stock awards vest in March each year so the excess tax benefits and deficiencies is greatest in the first quarter each year. The inclusion of excess tax benefits and deficiencies as a component of our income tax expense will increase volatility within our provision for income taxes as the amount of excess tax benefits or deficiencies from share-based compensation awards are dependent on our stock price at the date the restricted awards vest, our stock price on the date an option is exercised, and the quantity of options exercised. In August 2016, the FASB issued a new standard that clarifies how certain cash receipts and cash payments are presented and classified in the consolidated statement of cash flows. The University elected to early adopt this guidance in the first quarter of 2017 on a retrospective basis. There was no reclassification impact of the adoption on our consolidated statement of cash flows for the years ended December 31, 2017, 2016 and 2015, as our historical statements have been presented in accordance with this new guidance. In November 2016, the FASB issued a new standard that requires restricted cash and cash equivalents to be included with the amount of cash and cash equivalents that are reconciled on the consolidated statement of cash flows. The University elected to early adopt this guidance in the first quarter of 2017 on a retrospective basis, and accordingly, to conform to the current period presentation, we reclassified our restricted cash and cash equivalents to be included in the total of cash and cash equivalents presented at the bottom of our consolidated statement of cash flows for both the beginning and ending periods for our years ended December 31, 2017, 2016 and 2015. As a result, the amount of the change in our net cash provided by operating activities no longer includes the impact of the change in restricted cash and cash equivalents for either period. The following table summarizes the effects related to the adoption of both accounting standards (share-based compensation and restricted cash and cash equivalents) for the years ended December 31, 2016 and 2015: Consolidated Statement of Cash Flows Data:
|  | December 31, 2016 |  |  | December 31, 2015 |
|  | As reported |  |  | As adjusted |  |  | As reported |  |  | As adjusted |
Net cash provided by operating activities |  | $ | 218,286 |  |  | $ | 237,761 |  |  | $ | 173,900 |  |  | $ | 185,080 |
Net cash provided by (used in) financing activities |  | $ | 20,655 |  |  | $ | 10,727 |  |  | $ | (15,221 | ) |  | $ | (18,857 | )
Net increase (decrease) in cash and cash equivalents and restricted cash |  | $ | 22,940 |  |  | $ | 32,487 |  |  | $ | (42,202 | ) |  | $ | (34,658 | )
Cash and cash equivalents and restricted cash, beginning of period |  | $ | 23,036 |  |  | $ | 98,420 |  |  | $ | 65,238 |  |  | $ | 133,078 |
Cash and cash equivalents and restricted cash, end of period |  | $ | 45,976 |  |  | $ | 130,907 |  |  | $ | 23,036 |  |  | $ | 98,420
Recent Accounting Pronouncements | Recent Accounting Pronouncements In May 2014, the FASB issued “Revenue from Contracts with Customers, as amended.” The standard is a comprehensive new revenue recognition model that requires revenue to be recognized in a manner to depict the transfer of goods or services to a customer at an amount that reflects the consideration expected to be received in exchange for those goods or services. The accounting guidance also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgements and changes in judgements and assets recognized from costs incurred to obtain or fulfill a contract. In July 2015, the FASB approved a one-year delay in the effective date. The University will adopt this new standard January 1, 2018 using the modified retrospective method and providing certain additional disclosures as defined within the standard. The University has elected to apply this guidance retrospectively to all contracts at the date of initial application. Management has undertaken a review of contracts and revenue streams for all of our net revenues. The majority of our revenues are related to tuition, net of scholarships, due from our students. Tuition revenues, net of scholarships, are currently recognized pro-rata over the applicable period of instruction which the University believes is consistent with the revenue recognition method required by the new standard. The University will provide expanded disclosures pertaining to revenue recognition in our annual and quarterly filings beginning in the period of adoption. The University will clarify further its receivables, contract assets and contract liabilities reported in its consolidated balance sheets. The University will elect the short-term contract exemption with respect to disclosures associated with its performance obligations as all performance obligations as of the end of any reporting period have original terms of less than a year. Thus, we anticipate the adoption of this standard will not have a material impact on our consolidated financial statements, cash flows or results of operations. In January 2016, the FASB issued “Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities.” The standard addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. Most prominent among the amendments is the requirement for changes in the fair value of equity investments, with certain exceptions, to be recognized through net income rather than other comprehensive income (“OCI”). This standard is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, and early adoption is not permitted. Accordingly, the standard is effective for us on January 1, 2018. We are currently evaluating the impact that the standard will have on our consolidated financial statements. In February 2016, the FASB issued “Leases.” The standard establishes a right-of-use (“ROU”) model that requires a lessee to recognize a ROU asset and a lease liability on the balance sheet for all leases with lease terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. This standard is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018, and early adoption is permitted. Accordingly, the standard is effective for us on January 1, 2019 using a modified retrospective transition approach. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The University has begun evaluating the impact that the future adoption of this standard will have on our consolidated financial statements and we believe the adoption will slightly increase our assets and liabilities, and will expand our financial statement disclosures. In June 2016, the FASB issued “Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments”. The new guidance revises the accounting requirements related to the measurement of credit losses on financial instruments and the timing of when such losses are recorded. The standard is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019. Early adoption is permitted for fiscal years and interim periods within those years, beginning after December 15, 2018. Accordingly, the standard is effective for us on January 1, 2020 using a modified retrospective approach, and we are currently evaluating the impact that the standard will have on our consolidated financial statements. The University has determined that no other recent accounting pronouncements apply to its operations or could otherwise have a material impact on its consolidated financial statements.
