| c) | SHE reduced 19.72% of its capital to offset accumulated deficits in December 2019 and the Company’s ownership interest in SHE remained the same.

| e) | Chunghwa obtained 20.38% ownership interest in IISI in July 2020 and Chunghwa’s ownership interest in IISI increased to 51.54% by considering the previously held ownership interest in IISI. Chunghwa obtained over half of the seats of the Board of Directors of IISI; therefore, Chunghwa gained control over IISI and treated it as a subsidiary.
