Although the new fee disclosures that now come with 401(k) defined-contribution plans and IRAs aren’t light reading, the financials services research firm LIMRA recently found that less than two-thirds of Americans are spending much time pouring over the material.

That means they’re most likely missing data on how much fees will eat into their retirement savings.

You can review the key findings of LIMRA’s report here, while SmartMoney magazine also takes a look at the report.

So, do you know how much your 401(k) is charging you in fees? Have you received or read the new disclosure statements required by law? What's your take on the new regulations? Let us know your thoughts!
