Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Principles of Consolidation The accompanying consolidated financial statements include the accounts of UTI and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated. Use of Estimates The preparation of financial statements in accordance with accounting principles generally accepted in the United States requires management to make certain estimates and assumptions. Such estimates and assumptions affect the reported amounts of assets, liabilities, revenues and expenses and related disclosures of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates and assumptions, including those related to revenue recognition, our proprietary loan program, allowance for uncollectible accounts, investments, property and equipment, goodwill recoverability, self-insurance claim liabilities, income taxes, contingencies and stock-based compensation. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances. The results of our analysis form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions, and the impact of such differences may be material to our consolidated financial statements. Revenue Recognition Postsecondary education. Revenues consist primarily of student tuition and fees derived from the programs we provide after reductions are made for discounts and scholarships that we sponsor and for refunds for students who withdraw from our programs prior to specified dates. We apply the five-step model outlined in Accounting Standards Codification Topic 606, Revenue from Contracts from Customers (ASC 606). Tuition and fee revenue is recognized ratably over the term of the course or program offered. Approximately 98% of our revenues for each of the years ended September 30, 2018, 2017 and 2016 consisted of tuition. The majority of our core programs are designed to be completed in 33 to 102 weeks, and our advanced training programs range from 12 to 23 weeks in duration. We supplement our revenues with sales of textbooks and program supplies and other revenues, which are recognized as the transfer of goods or services occurs. Deferred revenue represents the excess of tuition and fee payments received as compared to tuition and fees earned and is reflected as a current liability in our consolidated balance sheets because it is expected to be earned within the next 12 months. Through our proprietary loan program, we, in substance, provide the students who participate in this program with extended payment terms for a portion of their tuition. Based on historical collection rates, we believe a portion of these loans are collectible, which results in a change in accounting due to our adoption of ASC 606 on October 1, 2017. Accordingly, we recognize tuition and loan origination fees financed by the loan and any related interest revenue under the effective interest method required under the loan based on this collection rate. For additional discussion of this adoption, see Note 3. Other. We provide dealer technician training or instructor staffing services to manufacturers. Revenues are recognized as transfer of the services occurs. Proprietary Loan Program In order to provide funding for students who are not able to fully finance the cost of their education under traditional governmental financial aid programs, commercial loan programs or other alternative sources, we established a private loan program with a bank. Under the terms of the proprietary loan program, the bank originates loans for our students who meet our specific credit criteria with the related proceeds used exclusively to fund a portion of their tuition. We then purchase all such loans from the bank at least monthly and assume all of the related credit risk. The loans bear interest at market rates ranging from approximately 7% to 10%; however, principal and interest payments are not required until six months after the student completes or withdraws from his or her program. After the deferral period, monthly principal and interest payments are required over the related term of the loan. The repayment term is up to 10 years. The bank provides these services in exchange for a fee at a percentage of the principal balance of each loan and related fees. Under the terms of the related agreement, we transfer funds for loan purchases to a deposit account with the bank in advance of the bank funding the loan, which secures our related loan purchase obligation. Such funds are classified as restricted cash in our consolidated balance sheet. All related expenses incurred with the bank or other service providers are expensed as incurred within educational services and facilities expense and were approximately $1.3 million, $1.3 million and $1.5 million for the years ended September 30, 2018, 2017, and 2016 respectively. Under ASC 606, the portion of tuition revenue related to the proprietary loan program is considered a form of variable consideration. We estimate the amount we ultimately expect to collect from the portion of tuition that is funded by the proprietary loan program, resulting in a note receivable. Estimating the collection rate requires significant management judgment. The estimated amount is determined at the inception of the contract, and we recognize the related revenue as the student progresses through school. Each reporting period, we update our assessment of the variable collection rate associated with the proprietary loan program. Prior to adopting ASC 606, we recognized revenue related to the proprietary loan program as cash was received. For additional discussion of this adoption, see Note 3. Restricted Cash Restricted cash includes the funds transferred in advance of loan purchases under our proprietary loan program, funds held for students from Title IV financial aid program funds that result in credit balances on a student’s account and funds held as collateral for certain of the surety bonds that our insurers issue on behalf of our campuses and admissions representatives with multiple states, which are required to maintain authorization to conduct our business. Changes in restricted cash that represent funds held for students or that result from changes in the collateralization required for surety bonds as described above are included in cash flows from operating activities on our consolidated statements of cash flows because these restricted funds are related to the core activity of our operations. All other changes in restricted cash are included in cash flows from investing activities on our consolidated statements of cash flows. Allowance for Uncollectible Accounts We maintain an allowance for uncollectible accounts for estimated losses resulting from the inability, failure or refusal of our students to make required payments. We offer a variety of payment plans to help students pay that portion of their education expenses not covered by financial aid programs or alternate fund sources, which are unsecured and not guaranteed. Management analyzes accounts receivable, historical percentages of uncollectible accounts, customer credit worthiness and changes in payment history when evaluating the adequacy of the allowance for uncollectible accounts. We use an internal group of collectors, augmented by third party collectors as deemed appropriate, in our collection efforts. Although we believe that our allowance is adequate, if the financial condition of our students deteriorates, resulting in an impairment of their ability to make payments, or if we underestimate the allowances required, additional allowances may be necessary, which would result in increased selling, general and administrative expenses in the period such determination is made. Investments Historically, we have invested in pre-funded municipal bonds, which are generally secured by escrowed-to-maturity U.S. Treasury notes. Municipal bonds represent debt obligations issued by states, cities, counties and other governmental entities, which earn interest that is exempt from federal income taxes. Additionally, we have invested in certificates of deposit issued by financial institutions and corporate bonds from large cap industrial and selected financial companies with a minimum credit rating of A. We held our investments until maturity and therefore classified these investments as held-to-maturity and reported them at amortized cost. Investments with an original maturity date of 90 days or less at the time of purchase were classified as cash equivalents and investments with a maturity date greater than one year at the end of the period were classified as non-current. We reviewed our held-to-maturity investments for impairment quarterly to determine if other-than-temporary declines in the carrying value have occurred for any individual investment. Other-than-temporary declines in the value of our held-to-maturity investments were recorded as expense in the period in which the determination was made. We determined that no other-than-temporary declines occurred in our held-to-maturity investments during the year ended September 30, 2017. At September 30, 2018, there are no investments reported. During the third quarter of 2017, we invested in various bond funds. These investments were held principally for resale in the near term and were classified as trading securities. Trading securities were recorded at fair value based on the closing market price of the security. Realized and unrealized gains and losses for trading securities were recognized in earnings and included in other income, net in the consolidated statements of loss. During the first quarter of 2018, we liquidated our investment in trading securities. Property and Equipment Property, equipment and leasehold improvements are recorded at cost less accumulated depreciation and amortization. Depreciation and amortization expense are calculated using the straight-line method over the estimated useful lives of the related assets. Amortization of leasehold improvements is calculated using the straight-line method over the remaining useful life of the asset or term of lease, whichever is shorter. Costs relating to software developed for internal use and curriculum development are capitalized and amortized using the straight-line method over the related estimated useful lives. Such costs include direct costs of materials and services as well as payroll and related costs for employees who are directly associated with the projects. Maintenance and repairs are expensed as incurred. We review the carrying value of our property and equipment for possible impairment whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. We evaluate our long-lived assets for impairment by examining estimated future cash flows. These cash flows are evaluated by using probability weighting techniques as well as comparisons of past performance against projections. Assets may also be evaluated by identifying independent market values. If we determine that an asset’s carrying value is impaired, we will write-down the carrying value of the asset to its estimated fair value and charge the impairment as an operating expense in the period in which the determination is made. There were no impairment charges required for the years ended September 30, 2018, 2017 and 2016. Goodwill Goodwill represents the excess of the cost of an acquired business over the estimated fair values of the assets acquired and liabilities assumed. Goodwill is reviewed at least annually for impairment, which may result from the deterioration in the operating performance of the acquired business, adverse market conditions, adverse changes in the applicable laws or regulations and a variety of other circumstances. Any resulting impairment charge would be recognized as an expense in the period in which impairment is identified. Our goodwill resulted primarily from the acquisition of our motorcycle and marine education business in 1998, and we recorded $8.2 million related to the goodwill allocated to our MMI Orlando, Florida campus that provides the related educational programs. Additionally, we recorded $0.8 million of goodwill related to the acquisition of BrokenMyth Studios, LLC (BMS) in February 2016. During the year ended September 30, 2018, due to the deteriorating operating performance of BMS and a decline in projected operating performance identified during our mid-year budget review, at June 30, 2018, we completed an interim test for impairment of the reporting unit and determined that the carrying value of this reporting unit exceeded its fair value, indicating goodwill impairment existed. The result of our valuation indicated that there was no remaining implied value attributable to goodwill in our BMS acquisition, and accordingly, we expensed all $0.8 million of the goodwill associated with that acquisition for the year ended September 30, 2018. Additionally, we determined that related definite-lived intangible assets were impaired, and we expensed the remaining $0.4 million remaining book value for the year ended September 30, 2018. Both impairment charges are included in our selling, general and administrative expenses in our condensed consolidated statement of loss. Our total recorded goodwill was $8.2 million as of September 30, 2018. We perform our annual goodwill impairment assessment during the fourth quarter of each fiscal year. Actual experience may differ from the amounts included in our assessment, which could result in impairment of our goodwill in the future. During the year ended September 30, 2018, we utilized a discounted cash flow model that incorporated estimated future cash flows for the next five years and an associated terminal value to determine the fair value of our MMI Orlando, Florida campus. Key management assumptions included in the cash flow model included future tuition revenues, operating costs, working capital changes, capital expenditures and a discount rate. Based upon our annual assessments, we determined that our goodwill was not impaired as of September 30, 2018 and that impairment charges were not required. Self-Insurance Plans We are self-insured for claims related to employee health and dental care and claims related to workers’ compensation. Liabilities associated with these plans are estimated by management with consideration of our historical loss experience, severity factors and independent actuarial analysis. Our claim liabilities are based on estimates, and while we believe the amounts accrued are adequate, the ultimate losses may differ from the amounts provided. Our recorded net liability related to self-insurance plans was $3.3 million as of September 30, 2018. Deferred Rent Liability We lease the majority of our administrative and educational facilities under operating lease agreements. Some lease agreements contain tenant improvement allowances, free rent periods or rent escalation clauses. In instances where one or more of these items are included in a lease agreement, we record a deferred rent liability on the consolidated balance sheet and record rent expense evenly over the term of the lease. Advertising Costs Costs related to advertising are expensed as incurred and totaled approximately $44.8 million, $38.6 million and $41.2 million for the years ended September 30, 2018, 2017, and 2016, respectively. Stock-Based Compensation Historically, we have issued restricted stock awards, restricted stock units and stock options. Restricted stock awards and restricted stock units are subject to vesting with service and performance conditions. We measure all share-based payments to employees at estimated fair value. We recognize the compensation expense for restricted stock awards and restricted stock units with only service conditions on a straight-line basis over the requisite service period. We did not grant stock options or restricted stock awards during the years ended September 30, 2018, 2017 and 2016. Shares issued under our equity compensation plans are new shares. Compensation expense associated with restricted stock awards, restricted stock units and performance units is measured based on the grant date fair value of our common stock, discounted for non-participation in anticipated dividends during the vesting period. The requisite service period for restricted stock awards, restricted stock units and performance units is generally the vesting period. We estimate the fair value of performance units using a Monte Carlo simulation which requires assumptions for expected volatility, risk-free rates of return, and dividend yields. Expected volatilities are derived using a method that calculates historical volatility over a period equal to the length of the measurement period for UTI. We use a risk-free rate of return that is equal to the yield of a zero-coupon U.S. Treasury bill that is commensurate with each measurement period, and we assume that any dividends paid were reinvested. Stock-based compensation expense of $1.9 million, $3.0 million and $4.9 million (pre-tax) was recorded for the years ended September 30, 2018, 2017 and 2016, respectively. The tax benefit related to stock-based compensation recognized was $0.5 million, $1.1 million and $1.9 million for the years ended September 30, 2018, 2017 and 2016, respectively. Income Taxes We recognize deferred tax assets and liabilities for the estimated future tax consequences of events attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. We also recognize deferred tax assets for net operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which the differences are expected to be recovered or settled. Deferred tax assets are reduced through a valuation allowance if it is more likely than not that the deferred tax assets will not be realized. Concentration of Risk Financial instruments that potentially subject us to concentrations of credit risk consist principally of cash and cash equivalents, restricted cash, investments and receivables. As of September 30, 2018, we held cash and cash equivalents of $58.1 million, restricted cash of $14.1 million and no investments. We place our cash and cash equivalents and restricted cash with high quality financial institutions and limit the amount of credit exposure with any one financial institution. We mitigate the concentration risk of our investments by limiting the amount invested in any one issuer. We mitigate the risk associated with our investment in corporate bonds by requiring a minimum credit rating of A. We extend credit for tuition and fees, for a limited period of time, to a majority of our students. A substantial portion is repaid through the student’s participation in federally funded financial aid programs. Transfers of funds from the financial aid programs to us are made in accordance with the ED requirements. Approximately 65% of our revenues, on a cash basis, were collected from funds distributed under Title IV Programs for the year ended September 30, 2018. This percentage differs from our Title IV percentage as calculated under the 90/10 rule due to the prescribed treatment of certain Title IV stipends under the rule. Additionally, approximately 17% of our revenues, on a cash basis, were collected from funds distributed under various veterans benefits programs for the year ended September 30, 2018. The financial aid and veterans benefits programs are subject to political and budgetary considerations. There is no assurance that such funding will be maintained at current levels. Extensive and complex regulations govern the financial assistance programs in which our students participate. Our administration of these programs is periodically reviewed by various regulatory agencies. Any regulatory violation could be the basis for the initiation of potential adverse actions, including a suspension, limitation, placement on reimbursement status or termination proceeding, which could have a material adverse effect on our business. ED and other regulators have increased the frequency and severity of their enforcement actions against postsecondary schools which have resulted in the imposition of material liabilities, sanctions, letter of credit requirements and other restrictions and, in some cases, resulted in the loss of schools’ eligibility to receive Title IV funds or in closure of the schools. If any of our institutions were to lose its eligibility to participate in federal student financial aid programs, the students at that institution would lose access to funds derived from those programs and would have to seek alternative sources of funds to pay their tuition and fees. Students obtain access to federal student financial aid through an ED 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 to pay their tuition and fees. The transfer of funds is from the financial aid program to the student, who then uses those funds to pay for a portion of the cost of their education. The receipt of financial aid funds reduces the student’s amounts due to us and has no impact on revenue recognition, as the transfer relates to the source of funding for the costs of education, which may occur either through Title IV or other funds and resources available to the student. Fair Value of Financial Instruments The carrying value of cash equivalents, restricted cash, accounts receivable, accounts payable, accrued liabilities and deferred tuition approximates their respective fair value as of September 30, 2018 and 2017 due to the short-term nature of these instruments. Comprehensive Income During the year ended September 30, 2012, we invested $4.0 million to acquire an equity interest in a joint venture (JV) related to the lease of our Lisle, Illinois campus facility. Historically, the JV used an interest rate cap to manage interest rate risk associated with its floating rate debt. This derivative instrument was designated as a cash flow hedge based on the nature of the risk being hedged. As such, the effective portion of the gain or loss on the derivative was initially reported as a component of the JV’s accumulated other comprehensive income or loss, net of tax, and was subsequently reclassified into earnings when the hedged transaction affects earnings. Any ineffective portion of the gain or loss was recognized in the JV’s current earnings. Due to our equity method investment in the JV, when the JV reports a current year component of other comprehensive income (OCI), we, as an investor, likewise adjust our investment account for the change in investee equity. In addition, we adjust our OCI for our share of the JV’s currently reported OCI item. During the three months ended December 31, 2017, the JV refinanced the facility loan and discontinued its use of an interest rate cap. Start-up Costs Costs related to the start-up of new campuses are expensed as incurred.

Summary of Significant Accounting Policies

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of UTI and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.

Use of Estimates

The preparation of financial statements in accordance with accounting principles generally accepted in the United States requires management to make certain estimates and assumptions. Such estimates and assumptions affect the reported amounts of assets, liabilities, revenues and expenses and related disclosures of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates and assumptions, including those related to revenue recognition, our proprietary loan program, allowance for uncollectible accounts, investments, property and equipment, goodwill recoverability, self-insurance claim liabilities, income taxes, contingencies and stock-based compensation. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances. The results of our analysis form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions, and the impact of such differences may be material to our consolidated financial statements.

Revenue Recognition

Postsecondary education. Revenues consist primarily of student tuition and fees derived from the programs we provide after reductions are made for discounts and scholarships that we sponsor and for refunds for students who withdraw from our programs prior to specified dates. We apply the five-step model outlined in Accounting Standards Codification Topic 606, Revenue from Contracts from Customers (ASC 606). Tuition and fee revenue is recognized ratably over the term of the course or program offered. Approximately 98% of our revenues for each of the years ended September 30, 2018, 2017 and 2016 consisted of tuition. The majority of our core programs are designed to be completed in 33 to 102 weeks, and our advanced training programs range from 12 to 23 weeks in duration. We supplement our revenues with sales of textbooks and program supplies and other revenues, which are recognized as the transfer of goods or services occurs. Deferred revenue represents the excess of tuition and fee payments received as compared to tuition and fees earned and is reflected as a current liability in our consolidated balance sheets because it is expected to be earned within the next 12 months.

Through our proprietary loan program, we, in substance, provide the students who participate in this program with extended payment terms for a portion of their tuition. Based on historical collection rates, we believe a portion of these loans are collectible, which results in a change in accounting due to our adoption of ASC 606 on October 1, 2017. Accordingly, we recognize tuition and loan origination fees financed by the loan and any related interest revenue under the effective interest method required under the loan based on this collection rate. For additional discussion of this adoption, see Note 3.

Other. We provide dealer technician training or instructor staffing services to manufacturers. Revenues are recognized as transfer of the services occurs.

Proprietary Loan Program

In order to provide funding for students who are not able to fully finance the cost of their education under traditional governmental financial aid programs, commercial loan programs or other alternative sources, we established a private loan program with a bank.

Under the terms of the proprietary loan program, the bank originates loans for our students who meet our specific credit criteria with the related proceeds used exclusively to fund a portion of their tuition. We then purchase all such loans from the bank at least monthly and assume all of the related credit risk. The loans bear interest at market rates ranging from approximately 7% to 10%; however, principal and interest payments are not required until six months after the student completes or withdraws from his or her program. After the deferral period, monthly principal and interest payments are required over the related term of the loan. The repayment term is up to 10 years.

The bank provides these services in exchange for a fee at a percentage of the principal balance of each loan and related fees. Under the terms of the related agreement, we transfer funds for loan purchases to a deposit account with the bank in advance of the bank funding the loan, which secures our related loan purchase obligation. Such funds are classified as restricted cash in our consolidated balance sheet.

All related expenses incurred with the bank or other service providers are expensed as incurred within educational services and facilities expense and were approximately $1.3 million, $1.3 million and $1.5 million for the years ended September 30, 2018, 2017, and 2016 respectively.

Under ASC 606, the portion of tuition revenue related to the proprietary loan program is considered a form of variable consideration. We estimate the amount we ultimately expect to collect from the portion of tuition that is funded by the proprietary loan program, resulting in a note receivable. Estimating the collection rate requires significant management judgment. The estimated amount is determined at the inception of the contract, and we recognize the related revenue as the student progresses through school. Each reporting period, we update our assessment of the variable collection rate associated with the proprietary loan program.

Prior to adopting ASC 606, we recognized revenue related to the proprietary loan program as cash was received. For additional discussion of this adoption, see Note 3.

Restricted Cash

Restricted cash includes the funds transferred in advance of loan purchases under our proprietary loan program, funds held for students from Title IV financial aid program funds that result in credit balances on a student’s account and funds held as collateral for certain of the surety bonds that our insurers issue on behalf of our campuses and admissions representatives with multiple states, which are required to maintain authorization to conduct our business. Changes in restricted cash that represent funds held for students or that result from changes in the collateralization required for surety bonds as described above are included in cash flows from operating activities on our consolidated statements of cash flows because these restricted funds are related to the core activity of our operations. All other changes in restricted cash are included in cash flows from investing activities on our consolidated statements of cash flows.

Allowance for Uncollectible Accounts

We maintain an allowance for uncollectible accounts for estimated losses resulting from the inability, failure or refusal of our students to make required payments. We offer a variety of payment plans to help students pay that portion of their education expenses not covered by financial aid programs or alternate fund sources, which are unsecured and not guaranteed. Management analyzes accounts receivable, historical percentages of uncollectible accounts, customer credit worthiness and changes in payment history when evaluating the adequacy of the allowance for uncollectible accounts. We use an internal group of collectors, augmented by third party collectors as deemed appropriate, in our collection efforts. Although we believe that our allowance is adequate, if the financial condition of our students deteriorates, resulting in an impairment of their ability to make payments, or if we underestimate the allowances required, additional allowances may be necessary, which would result in increased selling, general and administrative expenses in the period such determination is made.

Investments

Historically, we have invested in pre-funded municipal bonds, which are generally secured by escrowed-to-maturity U.S. Treasury notes. Municipal bonds represent debt obligations issued by states, cities, counties and other governmental entities, which earn interest that is exempt from federal income taxes. Additionally, we have invested in certificates of deposit issued by financial institutions and corporate bonds from large cap industrial and selected financial companies with a minimum credit rating of A. We held our investments until maturity and therefore classified these investments as held-to-maturity and reported them at amortized cost. Investments with an original maturity date of 90 days or less at the time of purchase were classified as cash equivalents and investments with a maturity date greater than one year at the end of the period were classified as non-current.

We reviewed our held-to-maturity investments for impairment quarterly to determine if other-than-temporary declines in the carrying value have occurred for any individual investment. Other-than-temporary declines in the value of our held-to-maturity investments were recorded as expense in the period in which the determination was made. We determined that no other-than-temporary declines occurred in our held-to-maturity investments during the year ended September 30, 2017. At September 30, 2018, there are no investments reported.

During the third quarter of 2017, we invested in various bond funds. These investments were held principally for resale in the near term and were classified as trading securities. Trading securities were recorded at fair value based on the closing market price of the security. Realized and unrealized gains and losses for trading securities were recognized in earnings and included in other income, net in the consolidated statements of loss. During the first quarter of 2018, we liquidated our investment in trading securities.

Property and Equipment

Property, equipment and leasehold improvements are recorded at cost less accumulated depreciation and amortization. Depreciation and amortization expense are calculated using the straight-line method over the estimated useful lives of the related assets. Amortization of leasehold improvements is calculated using the straight-line method over the remaining useful life of the asset or term of lease, whichever is shorter. Costs relating to software developed for internal use and curriculum development are capitalized and amortized using the straight-line method over the related estimated useful lives. Such costs include direct costs of materials and services as well as payroll and related costs for employees who are directly associated with the projects. Maintenance and repairs are expensed as incurred.

We review the carrying value of our property and equipment for possible impairment whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. We evaluate our long-lived assets for impairment by examining estimated future cash flows. These cash flows are evaluated by using probability weighting techniques as well as comparisons of past performance against projections. Assets may also be evaluated by identifying independent market values. If we determine that an asset’s carrying value is impaired, we will write-down the carrying value of the asset to its estimated fair value and charge the impairment as an operating expense in the period in which the determination is made. There were no impairment charges required for the years ended September 30, 2018, 2017 and 2016.

Goodwill

Goodwill represents the excess of the cost of an acquired business over the estimated fair values of the assets acquired and liabilities assumed. Goodwill is reviewed at least annually for impairment, which may result from the deterioration in the operating performance of the acquired business, adverse market conditions, adverse changes in the applicable laws or regulations and a variety of other circumstances. Any resulting impairment charge would be recognized as an expense in the period in which impairment is identified.

Our goodwill resulted primarily from the acquisition of our motorcycle and marine education business in 1998, and we recorded $8.2 million related to the goodwill allocated to our MMI Orlando, Florida campus that provides the related educational programs. Additionally, we recorded $0.8 million of goodwill related to the acquisition of BrokenMyth Studios, LLC (BMS) in February 2016.

During the year ended September 30, 2018, due to the deteriorating operating performance of BMS and a decline in projected operating performance identified during our mid-year budget review, at June 30, 2018, we completed an interim test for impairment of the reporting unit and determined that the carrying value of this reporting unit exceeded its fair value, indicating goodwill impairment existed. The result of our valuation indicated that there was no remaining implied value attributable to goodwill in our BMS acquisition, and accordingly, we expensed all $0.8 million of the goodwill associated with that acquisition for the year ended September 30, 2018. Additionally, we determined that related definite-lived intangible assets were impaired, and we expensed the remaining $0.4 million remaining book value for the year ended September 30, 2018. Both impairment charges are included in our selling, general and administrative expenses in our condensed consolidated statement of loss. Our total recorded goodwill was $8.2 million as of September 30, 2018. We perform our annual goodwill impairment assessment during the fourth quarter of each fiscal year. Actual experience may differ from the amounts included in our assessment, which could result in impairment of our goodwill in the future.

During the year ended September 30, 2018, we utilized a discounted cash flow model that incorporated estimated future cash flows for the next five years and an associated terminal value to determine the fair value of our MMI Orlando, Florida campus. Key management assumptions included in the cash flow model included future tuition revenues, operating costs, working capital changes, capital expenditures and a discount rate. Based upon our annual assessments, we determined that our goodwill was not impaired as of September 30, 2018 and that impairment charges were not required.

Self-Insurance Plans

We are self-insured for claims related to employee health and dental care and claims related to workers’ compensation. Liabilities associated with these plans are estimated by management with consideration of our historical loss experience, severity factors and independent actuarial analysis. Our claim liabilities are based on estimates, and while we believe the amounts accrued are adequate, the ultimate losses may differ from the amounts provided. Our recorded net liability related to self-insurance plans was $3.3 million as of September 30, 2018.

Deferred Rent Liability

We lease the majority of our administrative and educational facilities under operating lease agreements. Some lease agreements contain tenant improvement allowances, free rent periods or rent escalation clauses. In instances where one or more of these items are included in a lease agreement, we record a deferred rent liability on the consolidated balance sheet and record rent expense evenly over the term of the lease.

Advertising Costs

Costs related to advertising are expensed as incurred and totaled approximately $44.8 million, $38.6 million and $41.2 million for the years ended September 30, 2018, 2017, and 2016, respectively.

Stock-Based Compensation

Historically, we have issued restricted stock awards, restricted stock units and stock options. Restricted stock awards and restricted stock units are subject to vesting with service and performance conditions. We measure all share-based payments to employees at estimated fair value. We recognize the compensation expense for restricted stock awards and restricted stock units with only service conditions on a straight-line basis over the requisite service period. We did not grant stock options or restricted stock awards during the years ended September 30, 2018, 2017 and 2016. Shares issued under our equity compensation plans are new shares.

Compensation expense associated with restricted stock awards, restricted stock units and performance units is measured based on the grant date fair value of our common stock, discounted for non-participation in anticipated dividends during the vesting period. The requisite service period for restricted stock awards, restricted stock units and performance units is generally the vesting period.

We estimate the fair value of performance units using a Monte Carlo simulation which requires assumptions for expected volatility, risk-free rates of return, and dividend yields. Expected volatilities are derived using a method that calculates historical volatility over a period equal to the length of the measurement period for UTI. We use a risk-free rate of return that is equal to the yield of a zero-coupon U.S. Treasury bill that is commensurate with each measurement period, and we assume that any dividends paid were reinvested.

Stock-based compensation expense of $1.9 million, $3.0 million and $4.9 million (pre-tax) was recorded for the years ended September 30, 2018, 2017 and 2016, respectively. The tax benefit related to stock-based compensation recognized was $0.5 million, $1.1 million and $1.9 million for the years ended September 30, 2018, 2017 and 2016, respectively.

Income Taxes

We recognize deferred tax assets and liabilities for the estimated future tax consequences of events attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. We also recognize deferred tax assets for net operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which the differences are expected to be recovered or settled. Deferred tax assets are reduced through a valuation allowance if it is more likely than not that the deferred tax assets will not be realized.

Concentration of Risk

Financial instruments that potentially subject us to concentrations of credit risk consist principally of cash and cash equivalents, restricted cash, investments and receivables. As of September 30, 2018, we held cash and cash equivalents of $58.1 million, restricted cash of $14.1 million and no investments.

We place our cash and cash equivalents and restricted cash with high quality financial institutions and limit the amount of credit exposure with any one financial institution. We mitigate the concentration risk of our investments by limiting the amount invested in any one issuer. We mitigate the risk associated with our investment in corporate bonds by requiring a minimum credit rating of A.

We extend credit for tuition and fees, for a limited period of time, to a majority of our students. A substantial portion is repaid through the student’s participation in federally funded financial aid programs. Transfers of funds from the financial aid programs to us are made in accordance with the ED requirements. Approximately 65% of our revenues, on a cash basis, were collected from funds distributed under Title IV Programs for the year ended September 30, 2018. This percentage differs from our Title IV percentage as calculated under the 90/10 rule due to the prescribed treatment of certain Title IV stipends under the rule. Additionally, approximately 17% of our revenues, on a cash basis, were collected from funds distributed under various veterans benefits programs for the year ended September 30, 2018.

The financial aid and veterans benefits programs are subject to political and budgetary considerations. There is no assurance that such funding will be maintained at current levels. Extensive and complex regulations govern the financial assistance programs in which our students participate. Our administration of these programs is periodically reviewed by various regulatory agencies. Any regulatory violation could be the basis for the initiation of potential adverse actions, including a suspension, limitation, placement on reimbursement status or termination proceeding, which could have a material adverse effect on our business. ED and other regulators have increased the frequency and severity of their enforcement actions against postsecondary schools which have resulted in the imposition of material liabilities, sanctions, letter of credit requirements and other restrictions and, in some cases, resulted in the loss of schools’ eligibility to receive Title IV funds or in closure of the schools.

If any of our institutions were to lose its eligibility to participate in federal student financial aid programs, the students at that institution would lose access to funds derived from those programs and would have to seek alternative sources of funds to pay their tuition and fees. Students obtain access to federal student financial aid through an ED 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 to pay their tuition and fees. The transfer of funds is from the financial aid program to the student, who then uses those funds to pay for a portion of the cost of their education. The receipt of financial aid funds reduces the student’s amounts due to us and has no impact on revenue recognition, as the transfer relates to the source of funding for the costs of education, which may occur either through Title IV or other funds and resources available to the student.

Fair Value of Financial Instruments

The carrying value of cash equivalents, restricted cash, accounts receivable, accounts payable, accrued liabilities and deferred tuition approximates their respective fair value as of September 30, 2018 and 2017 due to the short-term nature of these instruments.

Comprehensive Income

During the year ended September 30, 2012, we invested $4.0 million to acquire an equity interest in a joint venture (JV) related to the lease of our Lisle, Illinois campus facility. Historically, the JV used an interest rate cap to manage interest rate risk associated with its floating rate debt. This derivative instrument was designated as a cash flow hedge based on the nature of the risk being hedged. As such, the effective portion of the gain or loss on the derivative was initially reported as a component of the JV’s accumulated other comprehensive income or loss, net of tax, and was subsequently reclassified into earnings when the hedged transaction affects earnings. Any ineffective portion of the gain or loss was recognized in the JV’s current earnings. Due to our equity method investment in the JV, when the JV reports a current year component of other comprehensive income (OCI), we, as an investor, likewise adjust our investment account for the change in investee equity. In addition, we adjust our OCI for our share of the JV’s currently reported OCI item. During the three months ended December 31, 2017, the JV refinanced the facility loan and discontinued its use of an interest rate cap.

Start-up Costs

Costs related to the start-up of new campuses are expensed as incurred.
