Contract Liabilities

As discussed in Note 4, in connection with its student tuition contracts, the Company has an obligation to provide free classes in the future should certain eligibility conditions be maintained (the Graduation Fund). In addition, the Company also has licensed certain of its non-credit bearing course content to a third party for which the Company received an upfront cash payment. Long-term contract liabilities represent the amount of revenue under these arrangements that the Company expects will be realized after one year.

Deferred Rent and Other Facility Costs and Loss on Facilities Not in Use

The Company records a liability for lease costs of campuses and non-campus facilities that are not currently in use (see Note 5). For facilities still in use, the Company records rent expense on a straight-line basis over the initial term of a lease. The difference between the rent payment and the straight-line rent expense is recorded as a liability.

Deferred Payments Related to Acquisitions

In connection with previous acquisitions, the Company acquired certain assets and entered into deferred payment arrangements with the sellers. The deferred payment arrangements are valued at approximately $3.6 million and $3.2 million as of December 31, 2017 and March 31, 2018, respectively. In addition, one of the sellers contributed $2.8 million to the Company representing the seller’s continuing interest in the assets acquired.

Lease Incentives

In conjunction with the opening of new campuses or renovating existing ones, the Company, in some instances, was reimbursed by the lessors for improvements made to the leased properties. In accordance with ASC 840-20, the underlying assets were capitalized as leasehold improvements and a liability was established for the reimbursements. The leasehold improvements and the liability are amortized on a straight-line basis over the corresponding lease terms, which generally range from five to ten years.
