Storage and Management of PCB
Since 1972, when the manufacture of products using polychlorinated biphenyl (PCB) was discontinued in Japan, Toshiba Group has kept PCB and PCB-containing products under strict surveillance, controlled them, and reported their storage to the relevant authorities in accordance with the Waste Management and Public Cleansing Act and the Act on Special Measures concerning Promotion of Proper Treatment of PCB Wastes in Japan. In addition to meeting the prescribed storage standards, the Group makes doubly sure through the installation of dikes and double containers and other measures that they are stored appropriately.

|---|---|---|
| High density | Proceed with disposal according to JESCO's disposal plan. | |
| Low density | Proceed with disposal at government-certified facilities. | Transformers: Analyze oil during maintenance. Formulate plans to upgrade or dispose of devices containing PCB. Condensers: Formulate plans to gradually upgrade fully sealed devices while taking care not to impair business activities. Formulate plans to dispose of devices containing PCB. |

Identifying environmental liabilities
Enforcement of the Act on Special Measures concerning Promotion of Proper Treatment of PCB Wastes, obliges PCB waste storage business operators to dispose of PCB wastes properly by March 2027. As of March 31, 2021 and 2022, Toshiba Group recorded environmental liabilities of approximately 4.8 billion yen and 14.8 billion yen respectively as PCB detoxification outsourcing expenses. These expenses were incurred in relation to the disposal of products containing PCB that were stored and managed in business and productions sites nationwide and their facilities. We will continue to grasp and disclose such information properly.
