A Yale University Law School Professor (with too much time on his hands) recently sent letters to 6,000 plan sponsors claiming that their 401(k) plans were “high cost,” that the plan sponsor may be violating its fiduciary duties by paying such high fees, and that he would soon be sharing these results with major media outlets. The letters aren’t sitting well with industry professionals. Some claim that the professor’s data is old, flawed and shouldn’t be published. This controversy will likely heat up in the coming months. If you received one of these letters, please contact us for steps you should take to protect yourself. And if you did not receive a letter, this is a good reminder to continue to monitor the reasonableness of your service provider’s fees.
