Insurer Allianz reported a 5.2 percent fall in second-quarter net income Friday, highlighting a negative impact from the sale of its traditional life insurance portfolio in Taiwan. Net profit came in at 1.89 billion euros ($2.19 billion) from 1.99 billion euros a year ago. The company said the negativity surrounding the sale was partially offset by lower income taxes. "The outlook for the rest of the year is very good," Giulio Terzariol, the chief financial officer of Allianz, told CNBC's "Squawk Box Europe" following the results. "Our revenue growth at 6 percent was very good and this is not only asset management, where we are growing double digits, we have strong growth in Life (and health insurance) and especially we had very healthy growth in property-casualty (insurance)."
