China Life says profit rises over 50 percent in H1

China Life Insurance Co, the nation's largest insurer, said its first-half profit probably rose more than 50 percent from a year earlier.

The figure was lifted by an increase in investment income combined with a decline in impairment losses, the Beijing-based insurer said in a statement to Hong Kong's stock exchange.

The preliminary estimate is based on unaudited numbers. China Life booked profit of 9.6 billion yuan ($1.6 billion), or 0.34 yuan per share, in the first half of last year.
