Investors have pulled some $42 billion from Pimco's flagship Total Return Bond Fund alone in the first six months of this year, according to Morningstar data, this follows the $103 billion redeemed from the fund in 2014 following Gross's departure. The fund's currents assets under management sit at around $102 billion, from a high of $293 billion in April 2013.
Gross, known as the 'Bond King' for his long tenure delivering stellar returns, shocked investors last September when he quit Pimco, the firm he co-founded for smaller rival Janus Capital.
"I think the Bill Gross discussion has really subsided and it is now much more the discussion about how to allocate the money best in the current financial market environment," Wemmer said.
"I think the overarching topic which also us as one of the largest investors in the world, with our own money is our main topic in all of our management discussions."
The insurer posted a 15 percent increase in profits attributable to shareholders, and said it expected strong operating profits for the year at the top of its target range of 10.8 billion euro, up around 5 percent from the year before.
