(c) Computation of MLR under section 833(c)(5)—(1) In general. Starting with the first taxable year beginning after December 31, 2015, and for all succeeding taxable years, an organization's MLR with respect to a taxable year is the ratio, expressed as a percentage, of the MLR numerator, as described in paragraph (c)(1)(i) of this section, to the MLR denominator, as described in paragraph (c)(1)(ii) of this section.

(i) MLR numerator. The numerator of an organization's MLR is the total premium revenue expended on reimbursement for clinical services and activities that improve health care quality provided to enrollees under its policies for the taxable year, computed using a three-year period in the same manner as those expenses are computed for the plan year for purposes of section 300gg-18(b) of title 42, United States Code and regulations issued under that section (see 45 CFR part 158).

(ii) MLR denominator. The denominator of an organization's MLR is the organization's total premium revenue for the taxable year, computed using a three-year period in the same manner as the total premium revenue is computed for the plan year for purposes of section 300gg-18(b) of title 42, United States Code and regulations issued under that section (see 45 CFR part 158).

(2) Transition rules. The transition rules in paragraphs (c)(2)(i) and (ii) of this section apply solely for the first taxable year beginning after December 31, 2013, and the first taxable year beginning after December 31, 2014.

(i) First taxable year beginning after December 31, 2013.

(ii) First taxable year beginning after December 31, 2014. For the first taxable year beginning after December 31, 2014, the numerator of an organization's MLR is the sum of the total premium revenue expended on reimbursement for clinical services and activities that improve health care quality provided to enrollees under its policies for the first taxable year beginning after December 31, 2013, and for the first taxable year beginning after December 31, 2014, and the denominator of an organization's MLR is the sum of the organization's total premium revenue for the first taxable year beginning after December 31, 2013, and for the first taxable year beginning after December 31, 2014.

If, for any taxable year, an organization's MLR is less than 85 percent, then beginning in that taxable year and for each subsequent taxable year for which the organization's MLR remains less than 85 percent, paragraphs (d)(1)(i) and (ii) of this section apply.
