The Pimco Income Fund (PIMIX), widely seen by investors and analysts as Pacific Investment Management’s new flagship fund, surpassed $100 billion in assets under management this week, even as fees were hiked on Oct. 2, two sources familiar with the matter said Friday.

The Pimco Income fund, overseen by Dan Ivascyn and Alfred Murata, raised its fees by 5 cents per $100 at the beginning of this month for most share classes, bringing expenses for the institutional-class shares to 50 cents per $100.

The increase in fees did not deter investors from Pimco Income, whose assets under management were $70.33 billion at the end of 2016 and $99.02 billion at the end of September.
