Sun Life Financial and Humana Join Together to Offer a Greater Choice of Dental Plans

The Employee Benefits Group division of Sun Life Financial Inc.* (NYSE: SLF, TSX: SLF) today announced that it has entered into an agreement with Humana (NYSE: HUM) to offer a greater choice of dental plans to employer groups in select markets. The marketing agreement allows employers to purchase Humana’s dental HMO ("DHMO”) as the low-cost option on a Dual Select Dental Plan, with a Sun Life plan* as the high-cost option. Plans will be available through Sun Life in Texas, Florida and Illinois.

"We’re excited to expand our dental plan offerings through this new relationship,” said Sue Schoch, Vice President of Dental Products at Sun Life Financial. "Adding DHMO to our Dual Select Plans allows us to offer customers another option when choosing a comprehensive dental plan for their employees.” Schoch went on to say, "Humana’s provider strength and tremendous reputation in these target markets made them a superior choice to round out our dental offerings.”

DHMO dental plans are offered by HumanaDental Insurance Company, and underwritten by CompBenefits Dental Inc., DentiCare Inc. and CompBenefits Company, all of which are Humana subsidiaries. With the DHMO, a member may see a primary care dentist, within the network, as often as necessary. There are no yearly maximums, no deductibles to meet and no waiting periods.

Plan administration will be seamless to employers, with both plans easily administered through Sun Life’s Plan Administrator Web portal. Employees have access to either Sun Life’s or Humana’s plan member sites, for user-friendly provider searches and online explanation of benefits.

"Sun Life shares our mission of providing customers with the plans and information they need to make the best decisions for themselves and their family members,” said Beth Bierbower, chief operating officer of Specialty Benefits at Humana. "That’s why we’re so excited that Sun Life’s network of brokers will now be able to offer Humana’s Dental HMO plan, along side their other options.”

Sun Life has more than 25 years experience providing group dental coverage with an average four-day turnaround on claims decisions. All of Sun Life’s dental plans are backed by a money-back service guarantee that covers claim service, customer service and overall satisfaction.

*Group Dental Insurance is underwritten by Sun Life and Health Insurance Co. U.S. (Wellesley Hills, MA.)
