# MBIA reports Q1 GAAP net loss of $73M; book value per share negative $10.29

## Summary
- Consolidated GAAP net loss $73M ($1.48 per diluted share) vs. loss of $106M ($2.16) in Q1 2021.
- Book value per share negative $10.29 as of March 31, 2022, down from negative $5.73 at Dec 31, 2021.
- Loss improvement driven by lower losses on Puerto Rico credits at National and lower salvage reductions on Zohar CDO claims at MBIA Corp.
- Net gains on financial instruments at fair value and foreign exchange decreased, partially offsetting loss improvement.
- Unrealized losses on AFS investments due to higher interest rates contributed to book value decline.
