China Variable Interest Entity	Note 19. China Variable Interest Entity On September 20, 2018 in preparation of the Spin-Off, we entered into an agreement by and between Honeywell and Garrett (the “China Purchase Agreement”) in which Honeywell agreed to sell to Garrett 100% of the equity interests of Honeywell Transportation Investment (China) Co., Ltd. (“Garrett China”) consisting of our primary operations in China, in exchange for upfront consideration of 8,444,077 shares of our common stock. No further consideration from Garrett was due. The China Purchase Agreement was amended to extend the date of the transfer of the equity interests in Garrett China from September 20, 2019 to June 30, 2020. Prior to the transfer of the equity interests, Garrett China was considered a variable interest entity for which Garrett is the primary beneficiary because the China Purchase Agreement provided Garrett control to direct the management and operation of Garrett China as well as all economic benefits and losses. The intent of the agreement was to place Garrett in the same position as if it already owned 100% of the equity interests of Garrett China. As the agreement was effective prior to the Spin-Off date while the Company and Garrett China were under common control of Honeywell, the assets and liabilities of Garrett China were recognized at their carrying amounts. On June 3, 2020 Honeywell transferred 100% of the equity interests of Garrett China in accordance with the China Purchase Agreement. Following the transfer, Garret continues to consolidate Garrett China. However, Garrett China is no longer considered to be a variable interest entity as Garrett now owns 100% of the equity interests. There was no change in the basis of the net assets of Garrett China as the transaction did not result in a change of control under U.S. GAAP.

Note 19. China Variable Interest Entity

On September 20, 2018 in preparation of the Spin-Off, we entered into an agreement by and between Honeywell and Garrett (the “China Purchase Agreement”) in which Honeywell agreed to sell to Garrett 100% of the equity interests of Honeywell Transportation Investment (China) Co., Ltd. (“Garrett China”) consisting of our primary operations in China, in exchange for upfront consideration of 8,444,077 shares of our common stock. No further consideration from Garrett was due. The China Purchase Agreement was amended to extend the date of the transfer of the equity interests in Garrett China from September 20, 2019 to June 30, 2020.

Prior to the transfer of the equity interests, Garrett China was considered a variable interest entity for which Garrett is the primary beneficiary because the China Purchase Agreement provided Garrett control to direct the management and operation of Garrett China as well as all economic benefits and losses. The intent of the agreement was to place Garrett in the same position as if it already owned 100% of the equity interests of Garrett China. As the agreement was effective prior to the Spin-Off date while the Company and Garrett China were under common control of Honeywell, the assets and liabilities of Garrett China were recognized at their carrying amounts.

On June 3, 2020 Honeywell transferred 100% of the equity interests of Garrett China in accordance with the China Purchase Agreement. Following the transfer, Garret continues to consolidate Garrett China. However, Garrett China is no longer considered to be a variable interest entity as Garrett now owns 100% of the equity interests. There was no change in the basis of the net assets of Garrett China as the transaction did not result in a change of control under U.S. GAAP.
