[1] | The short notional amount on our credit default swap positions was approximately $213 million at December 31, 2024.

The short notional amount on our credit default swap positions was approximately $2.5 billion as of December 31, 2023. However, because credit spreads cannot compress below zero, our downside short notional exposure to loss is $0.4 billion as of December 31, 2023.
