For the year ended December 31, 2022, other expense, net was $223.9 million primarily related to foreign exchange losses resulting from the strengthening of the U.S. dollar and the revaluation impact of foreign currencies held in U.S. functional currency subsidiaries and unrealized losses on our equity investments. These losses were partially offset by increased income from government subsidies.
Other (Expense) Income, Net Other expense, net for the year ended December 31, 2024 was $12.6 million, due to foreign exchange losses, primarily from holding net monetary assets denominated in the RMB at certain U.S. dollar functional entities, including BeiGene, Ltd. (the “Parent Company”), and unrealized losses on equity investments, partially offset by government subsidy income.

The increase was partially offset by lower external clinical trial costs for TEVIMBRA (tislelizumab) and ociperlimab due to certain studies winding down, lower upfront license fees under collaboration agreements and a decrease in the expense recognized on co-development fees to Amgen.
The increase in external research and development expenses for the year ended December 31, 2024 was primarily attributable to higher upfront license and development milestone fees and increases in Amgen co-development expense, partially offset by lower external clinical trial costs.
