Variable Interest Entity, Consolidated, Assets, Pledged [Abstract] |  |
Variable Interest Entity Disclosure [Text Block] | VARIABLE INTEREST ENTITIES Effective November 30, 2019, we, through our wholly owned subsidiary, SGHDAL LLC (“Southgate”), acquired the remaining membership and voting interests in our subsidiary, Southgate Homes DFW LLC. As a result, Southgate became an indirect wholly owned subsidiary of the Company, was no longer considered a VIE and was consolidated based on the majority voting interest pursuant to ASC 810. Effective December 31, 2019, we, through our wholly owned subsidiary, CLH20, LLC (“Centre Living”), acquired the remaining membership and voting interests in our subsidiary, Centre Living Homes, LLC, and we contributed certain real estate inventory assets to Centre Living. As both Centre Living, to which ownership interests were assigned and assets and liabilities were transferred, and Centre Living Homes, LLC were controlled by the Company on December 31, 2019, the acquisition of the remaining membership interest and the contribution of the real estate inventory assets were accounted for at carrying amounts on Centre Living Homes, LLC’s books on the date of the transfer, pursuant to provisions of ASC 805 that govern transactions between entities under common control. Subsequently, the prior owner of a portion of the membership and voting interests in Centre Living Homes, LLC acquired a ten percent membership and voting interest in Centre Living for $3.6 million. As a result, as of December 31, 2019, Centre Living was an indirect subsidiary in which the Company owned a ninety percent membership interest and a ninety percent voting interest, was no longer considered a VIE and was consolidated based on the majority voting interest pursuant to ASC 810. Consolidated VIEs CB JENI Homes DFW LLC (“CB JENI”) and The Providence Group of Georgia LLC (“TPG”), the controlled builders based in Dallas and Atlanta, respectively, in which the Company owns a 50% equity interest and a 51% voting interest, are deemed to be VIEs for which the Company is considered the primary beneficiary. We sell finished lots and option lots from third-party developers to these controlled builders for their homebuilding operations and provide them with construction financing and strategic planning. The board of managers of each of these controlled builders has the power to direct the activities that significantly impact the controlled builder’s economic performance. Pursuant to the Company’s agreements with these controlled builders, it has the ability to appoint two of the three members to the controlled builder’s board of managers. A majority of the board of managers constitutes a quorum to transact business. No action can be approved by the board of managers without the approval from at least one individual whom the Company has appointed at the controlled builder. The Company has the ability to control the activities of each controlled builder that most significantly impact the controlled builder’s economic performance. Such activities include, but are not limited to, involvement in the day to day capital and operating decisions, the ability to determine the budget and plan, the ability to control financing decisions, and the ability to acquire additional land or dispose of land. In addition, the Company has the right to receive the expected residual returns and obligation to absorb the expected losses of each controlled builder through the pro rata profits and losses we are allocated based on our ownership interest. Therefore, the financial statements of the Dallas and Atlanta-based controlled builders are consolidated in the Company’s consolidated financial statements following the variable interest model. The aggregated carrying amounts of assets and liabilities of CB JENI and TPG consolidated following the variable interest model were $279.8 million and $265.3 million, respectively, as of December 31, 2019 and $262.9 million and $234.0 million, respectively, as of December 31, 2018. The noncontrolling interests attributable to the 50% minority interests owned by the Dallas and Atlanta-based controlled builders were included as noncontrolling interests in the Company’s consolidated financial statements. The creditors of the above controlled builders have no recourse against the Company. Unconsolidated VIEs Land and lot option purchase contracts The Company evaluates all option contracts to purchase land and lots to determine whether they are VIEs and, if so, whether the Company is the primary beneficiary of counterparts of these option contracts. Although the Company does not have legal title to the optioned land or lots, if the Company is deemed to be the primary beneficiary of or makes a significant deposit for optioned land or lots, it may need to consolidate the land or lots under option at the purchase price of the optioned land or lots. As of December 31, 2019 and 2018, the Company’s exposure to loss related to its option contracts with third parties primarily consisted of its non-refundable option deposits. Following VIE evaluation, it was concluded that the Company was not the primary beneficiary in any of the VIEs related to land or lot option contracts as of December 31, 2019 and 2018. EJB River Holdings, LLC In December 2018, EJB River Holdings, LLC joint venture (“EJB River Holdings”) was formed by TPG with the purpose to acquire and develop a tract of land in Gwinnett County, Georgia. In May 2019, East Jones Bridge, LLC, a Georgia limited liability company (“EJB”) was admitted as a member of EJB River Holdings, which resulted in TPG and EJB each having a 50% ownership interest in EJB River Holdings. EJB River Holdings had no activity in the period from its formation until October 2019. In October 2019, EJB River Holdings received two $5.0 million initial contributions from its two members, TPG and EJB. In December 2019, two additional contributions of $0.3 million were made by TPG and EJB to EJB River Holdings. Per EJB River Holdings’ operating agreement, TPG and EJB share equally in the profits and losses of EJB River Holdings, with the exception of certain customary fees. In October 2019, EJB River Holdings issued two loans with the total maximum amount of borrowings of $21.9 million to finance its land acquisition and development in Gwinnett County, Georgia. One of the investors in EJB issued a personal guarantee on one of the loans in the amount of $9.4 million. Subsequently, in October 2019, a wholly owned subsidiary of the Company provided a limited $2.0 million guarantee to the investor in EJB. The approximate term of the guarantee is 35 months. In the event EJB River Holdings defaults on its $9.4 million loan and the investor in EJB makes the $9.4 million payment under his personal guarantee, the maximum potential amount of future payments that the Company could be required to make under its limited guarantee is $2.0 million. As of December 31, 2019, the Company has no current liability related to the guarantee obligation as the payment risk of the guarantee has been assessed to be very low. Following the analysis of the above facts and provisions of EJB River Holdings’ operating agreement, the Company has determined that EJB River Holdings is a VIE in which the Company is not the primary beneficiary. Therefore, the investment in EJB River Holdings was treated as an unconsolidated investment under the equity method of accounting and was included in investments in unconsolidated entities in the Company’s consolidated balance sheets. As of December 31, 2019, the carrying amounts of assets and liabilities of EJB River Holdings were $23.7 million and $13.1 million, respectively. Assets were comprised of real estate inventory and cash, whereas the liabilities were comprised of loans and interest payable. As of December 31, 2019, the Company’s maximum exposure to loss as a result of its involvement with EJB River Holdings was $7.3 million, represented by the sum of the Company’ investment in EJB River Holdings of $5.3 million and the $2.0 million limited guarantee described above. |
