Feb 13 (Reuters) - American International Group Inc posted a fourth-quarter adjusted loss on Wednesday, as the insurer's net investment income fell 18 percent due to volatility in the financial markets.
The company posted an adjusted loss of $559 million, or 63 cents per share, for the quarter ended Dec. 31, compared with an adjusted profit of $526 million, or 57 cents per share, a year earlier.
Total net investment income fell to $2.8 billion from $3.5 billion a year ago.
Net pre-tax catastrophe loss of $798 million was near the upper end of its expected range due to claims related to Hurricane Michael and the California Wildfires. (Reporting by Diptendu Lahiri in Bengaluru; Editing by Anil D'Silva)
