German insurance giant Allianz reported first quarter results on Wednesday that were hit by hefty outflows from its Pimco asset management subsidiary.

Pimco—one of the world's largest bond houses—recorded net outflows of 21.7 billion euros ($30.0 billion) between January and March 2014. This contributed to an 18.9 percent decline in operating revenues for Allianz's asset management business, although its overall assets under management grew 1.6 percent to 1,765 billion euros.
