The performance represents a landmark for Manulife, which initially set a goal in 2012 to achieve annual earnings of C$4 billion ($3.1 billion) by 2015 but later pushed back its expectation to 2016, citing tougher economic conditions.

The company then warned last February it would be difficult to achieve the target in 2016, partly because weak oil prices had hit the value of its investments in the energy sector. However, a partial recovery in the price of oil and a better performance from its fixed income investments helped it achieve the milestone.

"Earlier in the year I was not sure that we would achieve that and that's a real landmark for the company. I think it bodes very well for us as an organization," Chief Financial Officer Steve Roder said in an interview on Thursday.

The company's core earnings, excluding one-off items and market movements, totaled C$4.02 billion ($3.06 billion), or C$1.96 Canadian cents per share in the full year, compared with C$3.43 million, or C$1.68 Canadian cents per share, a year earlier. Analysts on average had expected earnings of C$1.85 per share, according to Thomson Reuters I/B/E/S.

That growth was driven by investment gains of C$197 million and benefited from improved results in Asia, where insurance sales surged by a record 27 percent compared to 2015.

"Underlying earnings growth remained impressive, particularly in Asia, which should continue to fuel a positive outlook," said analyst John Aiken of Barclays Capital in Toronto.

Manulife reported an 11 percent increase in its quarterly dividend to C$0.205 per share.

Manulife is expanding in Asia as the region's burgeoning middle class looks to save and invest. It has benefited from a partnership with Singapore's DBS Group, agreed in 2015, in which Manulife sells its products through the lender’s Asian branch network.

Shares in Manulife have risen by more than a quarter since Donald Trump's election as U.S. president in November, driven by expectations Trump's plans to spend billions on infrastructure and other initiatives to boost growth in the U.S. economy will lead to inflation and higher interest rates.
