14. Segment Information

We provide products and services and report results through our Annuities, Retirement Plan Services, Life Insurance and Group Protection segments. As discussed in Note 3, we completed the acquisition of Liberty Life during the second quarter of 2018. Related results are included within the Group Protection segment. We also have Other Operations, which includes the financial data for operations that are not directly related to the business segments. Our reporting segments reflect the manner by which our chief operating decision makers view and manage the business. A discussion of these segments and Other Operations is found in Note 21 of our 2018 Form 10-K.

Segment operating revenues and income (loss) from operations are internal measures used by our management and Board of Directors to evaluate and assess the results of our segments. Income (loss) from operations is GAAP net income excluding the after-tax effects of the following items, as applicable:

Realized gains and losses associated with the following (“excluded realized gain (loss)”):

Sales or disposals and impairments of securities;

Changes in the fair value of derivatives, embedded derivatives within certain reinsurance arrangements and trading securities (“gain (loss) on the mark-to-market on certain instruments”);

Changes in the fair value of the derivatives we own to hedge our GDB riders reflected within our variable annuities;

Changes in the fair value of the embedded derivatives of our GLB riders reflected within variable annuity net derivative results accounted for at fair value;

Changes in the fair value of the embedded derivative liabilities related to index call options we may purchase in the future to hedge contract holder index allocations applicable to future reset periods for our indexed annuity products accounted for at fair value (“indexed annuity forward-starting option”); and

Changes in the fair value of equity securities;

Changes in reserves resulting from benefit ratio unlocking on our GDB and GLB riders (“benefit ratio unlocking”);

Income (loss) from reserve changes, net of related amortization, on business sold through reinsurance;

Losses from the impairment of intangible assets;

Income (loss) from discontinued operations;

Acquisition and integration costs related to mergers and acquisitions; and

Operating revenues represent GAAP revenues excluding the pre-tax effects of the following items, as applicable:

Excluded realized gain (loss);

Revenue adjustments from the initial adoption of new accounting standards;

Amortization of DFEL arising from changes in GDB and GLB benefit ratio unlocking; and
