1.    BASIS OF PRESENTATION
Basis of Presentation
Protective Life Insurance Company (the “Company”), a stock life insurance company, was founded in 1907. The Company is a wholly owned subsidiary of Protective Life Corporation (“PLC”), an insurance holding company. On February 1, 2015, PLC became a wholly owned subsidiary of The Dai-ichi Life Insurance Company, Limited, a kabushiki kaisha organized under the laws of Japan (now known as Dai-ichi Life Holdings, Inc., “Dai-ichi Life”), when DL Investment (Delaware), Inc., a wholly owned subsidiary of Dai-ichi Life, merged with and into PLC (the “Merger”). Prior to February 1, 2015, PLC’s stock was publicly traded on the New York Stock Exchange. Subsequent to the Merger, PLC remained an SEC registrant within the United States until January 23, 2020, when it suspended its reporting obligations with the SEC under the Securities Exchange Act of 1934. The Company has continued to be an SEC registrant for financial reporting purposes in the United States. The Company markets individual life insurance, credit life and disability insurance, guaranteed investment contracts, guaranteed funding agreements, fixed and variable annuities, and extended service contracts throughout the United States. The Company also maintains a separate segment devoted to the acquisition of insurance policies from other companies. PLC is a holding company with subsidiaries that provide financial services through the production, distribution, and administration of insurance and investment products.
