[1] | In 2022, one of Teva’s U.S. subsidiaries was determined to be insolvent for tax purposes (i.e., its liabilities exceeded the fair market value of its assets), mainly in light of its accumulated operational losses. Consequently, Teva recognized on its 2022 tax return, a worthless stock deduction of approximately $4.2 billion, with related tax benefit of approximately $909 million.
