(Adds details; background on hurricanes)
Dec 5 (Reuters) - Bank of Montreal, Canada's fourth-biggest lender, on Tuesday reported a decline in quarterly earnings due to higher reinsurance claims following hurricanes that hit parts of the United States and Puerto Rico.
Insurers were clobbered by storms in August and September, when Hurricanes Harvey and Irma struck within less than two weeks of each other causing billions of dollars in destruction in Texas and Florida. Hurricane Maria followed weeks later, devastating Puerto Rico.
The company said it recorded reinsurance claims of C$112 million ($88.58 million) due to the hurricanes in the fourth quarter ended Oct. 31.
Net income attributable to shareholders fell to C$1.23 billion ($973.18 million), or C$1.81 per share, from C$1.34 billion, or C$2.02 per share, a year earlier.
However, net income from BMO's Canadian personal and commercial banking unit rose 6 percent.
Overall, revenue rose 7.1 percent to C$5.66 billion.
