AIG beats second-quarter profit estimates on robust underwriting— American International Group beat analysts’ estimates for second–quarter profit on Thursday, as strong underwriting gains helped cushion an uptick in catastrophe-related claims. Insurers have had an upbeat first half as higher premiums and disciplined underwriting have better positioned them to weather catastrophe losses. After-tax adjusted profit rose 10% to $2 per share in the second quarter, comfortably beating Wall Street expectations of $1.92, according to estimates compiled by LSEG. AIG said it returned $904 million of capital to shareholders in the second quarter. Last month, property and casualty insurer Travelers also swept past Wall Street estimates for second–quarter profit thanks to lower catastrophe losses and robust investment income.
