Principal Financial Group / Do not invest in them
In the 3rd Quarter 2008, Principal arbitrarily decided to block any transfers out of its Real Estate fund, which was losing money, and has consistently lost money ever since. And there's no light at the end of the tunnel when they will allow investors to transfer their savings. Principal advised investors of the block at approximately 9:00pm on the night they implemented it at midnight -- 3 hours notice under cover of darkness, obviously to not allow investors enough time to protect themselves.
Principal continues its advertisements that it works in the best interest of investors -- that certainly couldn't be further from the truth with my experience.
