Effective January 1, 2013, Massachusetts Mutual Life Insurance Company (MassMutual) acquired The Hartford's Retirement Plans Group. During a transition period you will see branding of both The Hartford and MassMutual as well as legal notices of each company. And, as you use our online services, at times you will be on Hartford branded sites and at other times, you will be on MassMutual websites. Please continue to access your account through the same website you use today. While your retirement plan is now administered by MassMutual, all of your plan's features will remain the same unless specific changes are made by your plan sponsor.
