Real Estate Assets Held For Development And Sale [Abstract]
Assets Held for Sale	Note 14 – Assets Held for Sale Assets held for sale consist of approximately 16 acres of raw land located in Plano, Texas, that the Company is in the process of selling. The land was originally acquired as a site to construct a future corporate headquarters. The Company decided that its existing headquarters is adequate and construction of a new headquarters building is not necessary. The Company has been actively marketing the land and has a signed contract to sell the land to an unaffiliated third party for cash. During the second quarter of 2019, the buyer received necessary local zoning approval for its building plans. We anticipate the sale will close within the next 12 months. We have not recorded any impairment charges in connection with the land.

Tabular disclosure of long lived assets held for sale. Disclosure may include the description of the facts and circumstances leading to the expected disposal, manner and timing of disposal, the carrying value of the assets held for sale, the gain (loss) recognized in the income statement and the income statement caption that includes that gain (loss).
