During the fiscal year ended March 31, 2020, the Group disposed of a 3.7% equity interest in PT Bank SMBC Indonesia Tbk (formerly known as PT Bank BTPN Tbk) to a third-party investor. Subsequently, in the fiscal year ended March 31, 2024, the Group disposed of an additional 3.7% to other third-party investors. The disposals were undertaken to ensure that PT Bank SMBC Indonesia
 
Tbk is compliant with the free float requirement under the Indonesia Stock Exchange’s Rule. The Group had also entered into a commercial arrangement where the economic exposure resulting from the disposals is being retained. Therefore, the disposals have not resulted in a decrease in the Group’s ownership interests.
