The ETF Professor: FlexShares ETFs, the fund family recently introduced by Northern Trust (Nasdaq: NTRS), announced today that its lineup of four ETFs has surpassed a combined $500 million in assets under management.

“To exceed the half-billion-dollar watermark in less than four months is an exciting milestone,” said Shundrawn Thomas, head of Northern Trust’s Exchange Traded Funds Group. “The market has responded positively to our focus on distinctive products that address real investor needs.”

The FlexShares Morningstar Global Upstream Natural Resources Index ETF (NYSE: GUNR) has almost $182 million in AUM, according to the FlexShares Web sites and the ETF has already been profiled in some circles.

The FlexShares iBoxx 3-Year Target Duration TIPS (NYSE: TDTT) has almost $149.5 million in AUM while the FlexShares iBoxx 5-Year Target Duration TIPS Index Fund (NYSE: TDTF) has over $147 million in AUM.

The FlexShares Morningstar U.S. Market Factor Tilt Index ETF (NYSE: TILT) is by far the smallest of the FlexShares quartet with $31.7 million in AUM.

Despite being the smallest of the four FlexShares ETFs, TILT has easily been the best performer since inception, gaining 15% while GUNR is higher by 2.4%
