The 8.3 magnitude earthquake in Chile and resulting floods hit Liberty Mutual hard in 2015. Profits at the property and casual insurance company sunk 72% due in part to higher losses from catastrophe claims, both in Chile as well as other parts of the world. The Boston-based insurer also invests in energy projects including oil and gas wells, but those investments have fared poorly as energy prices have fallen, contributing to Liberty Mutual’s earnings declines. The 104-year-old company’s revenues also fell nearly 1% in 2015, though it still managed to climb five spots on the Fortune 500, to No. 73.
