Message on Fidelity NetBenefits website for TVA 401K participants:
Due to unforeseen circumstances, the Share Class changes scheduled for December 4, 2013, were delayed. The new date of the Share Class changes is scheduled for February 18, 2014. If you would like to review the upcoming changes, please reference the letter posted on NetBenefits® under Plan Information and Documents named, “Share Class Changes.”
The changes were expected to occur on February 5, 2014 after the first delay (see here), but they have been delayed again until February 18, 2014.
I apologize for the delays.
