Asset Impairment Charges [Text Block]	Impairment Charges In July 2018, the Company entered into a new lease agreement with Children’s Learning Adventure USA (CLA) related to 21 open schools which replaced the prior lease arrangements and continued on a month-to-month basis. The lease agreement provided for monthly rent of $1.0 million along with the monthly reimbursement for property taxes of approximately $170 thousand. In February 2019, CLA and the Company entered into agreements (collectively, the PSA) providing for the purchase and sale of certain assets associated with the businesses located at the 21 operating CLA properties whereby the Company can nominate a third party operator to take an assignment and transfer of such assets from CLA and to receive certain beneficial rights under various related ancillary agreements. Additionally, in February 2019, the Company entered into leases of those properties with another early childhood education operator, which are contingent upon the transfer or surrender of each property pursuant to the PSA. The Company had $246.2 million classified in rental properties, net, in the accompanying consolidated balance sheets at December 31, 2018 for these 21 schools and determined that the estimated undiscounted future cash flow exceed the carrying values of these properties. See Note 19 for further discussion regarding CLA. In addition, during the year ended December 31, 2018, CLA also relinquished control of four of the Company’s properties that were still under development as the Company no longer intends to develop these properties for CLA. As a result, the Company revised its estimated undiscounted cash flows for these four properties, considering shorter expected holding periods, and determined that those estimated cash flows were not sufficient to recover the carrying values of these four properties. During the year ended December 31, 2018, the Company determined the estimated fair value of these properties using Level 3 inputs, including independent appraisals of these properties, and reduced the carrying value of these assets to $9.8 million, recording an impairment charge of $16.5 million. The charge was primarily related to the cost of improvements specific to the development of CLA’s prototype. During the year ended December 31, 2018, the Company recognized a $10.7 million impairment charge related to the Company’s guarantees of the payment of two economic development revenue bonds secured by leasehold interests and improvements at two theatres in Louisiana. In accordance with Topic 460, Guarantees, the Company recorded an asset and liability at the inception of the guarantees at fair value, which represented the Company's obligation to stand ready to perform under the terms of the guarantees. During the year ended December 31, 2018, the Company determined that a portion of its asset was no longer recoverable and recorded an impairment charge of $7.8 million. A contingent future obligation is recognized in accordance with the provisions of Topic 450, Accounting for Contingencies. In the case of the Company’s guarantees, the contingent future obligation is the future payment of the bonds by the Company. At the inception of the guarantees, the Company determined that its future payment of the bonds was not probable, therefore no contingent future obligation was recorded. For the year ended December 31, 2018, the Company determined that its future payment on a portion of the bond obligations was probable due to inadequate performance of the theatre properties and failure of the debtor under the bonds to perform. Accordingly, for the year ended December 31, 2018, the Company recorded an incremental contingent liability of $2.9 million, which in addition to the $7.8 million discussed above, resulted in a total impairment charge recognized relating to the guarantees of $10.7 million. For a discussion of impairment charges recorded during the year ended December 31, 2017, totaling $10.2 million, see Note 7. There were no impairment charges recorded for the year ended December 31, 2016.
