In January 2013, we acquired UnitedHealth Group Incorporated's Medicaid business in South Carolina. As of December 31, 2013, WellCare of South Carolina, Inc., formerly known as UnitedHealthcare of South Carolina, Inc.,
PDP - membership decreased approximately 72,000 compared to December 31, 2012 as a result of our 2013 PDP bids, which resulted in the reassignment to other plans, effective January 1, 2013, of certain members who were auto-assigned to us in 2012 or prior years.
PDP - membership decreased by approximately 107,000 compared to December 31, 2011 as a result of our 2012 PDP bids, which resulted in the reassignment to other plans, effective January 1, 2012, of members who were auto-assigned to us in 2011 or prior years.
The health insurance industry fee imposed by the Affordable Care Act beginning in 2014 is not deductible for income tax purposes. Due principally to the impact of the fee, we anticipate that our 2014 effective income tax rate will be in the range of 50.5% to 51.5%.
Excluding Medicaid premium taxes, Medicaid premium revenue for the year ended December 31, 2012 increased 25% when compared to the same period in 2011. The increase was driven mainly by the Kentucky Medicaid program operating for a full year in 2012, compared to two months in 2011, as well as membership growth in that program, both the managed long-term care program and the carve-in of the pharmacy benefit in our New York Medicaid program, membership growth in Florida, and rate increases implemented in most markets in late 2011. The increase in Kentucky Medicaid premiums also reflects the open enrollment in November 2012. Partially offsetting these increases was a $21.4 million reduction of premium revenue recorded during the second half of 2012 related to a reconciliation of duplicate member records in Georgia dating back to the beginning of the program in 2006.
The following table sets forth the summarized results of operations and other relevant performance measures for our MA segment for the years ended December 31, 2013, 2012 and 2011:
For the MA segment, we currently expect the MBR in 2014 to be in the range of approximately 85% and 86%, compared to 86.6% in 2013.
Based on the outcome of our 2013 PDP bids, our plans were below the benchmarks in 14 of the 34 CMS regions and within the de minimis range of the benchmark in five other CMS regions. As a result of the 2013 bids, in 2013 we were auto-assigned newly-eligible members into our plans for the 14 regions that were below the benchmark. We retained our previously auto-assigned members in the five regions in which we bid within the de minimis range; however, we were not auto-assigned new members in those regions during 2013. Membership declined 72,000, or 8%, at December 31, 2013 compared to December 31, 2012, due primarily to the reassignment in January 2013 to other plans of members who were previously auto-assigned to us (primarily California), offset in part by additional auto-assignments to us in other regions and an increase in the members who actively chose our PDP plans.
In addition to the foregoing requirements, our regulated subsidiaries are subject to restrictions on their ability to make dividend payments, loans and other transfers of cash. Dividend restrictions vary by state, but the maximum amount of dividends which can be paid without prior approval from the applicable state is subject to restrictions relating to statutory capital, surplus and net income for the previous year. Some states require prior approval of all dividends, regardless of amount. States may disapprove any dividend that, together with other dividends paid by a subsidiary in the prior 12 months, exceeds the regulatory maximum as computed for the subsidiary based on its statutory surplus and net income. For the years ended December 31, 2013, 2012 and 2011, we received $147.0 million, $192.0 million and $92.0 million respectively, in cash dividends from our regulated subsidiaries.
In some instances, our fixed Medicaid premiums are subject to risk score adjustments based on the acuity of our membership. Generally, the risk score is determined by the state agency's analysis of encounter submissions of processed claims data to determine the acuity of our membership relative to the entire state's Medicaid membership.
