IMPORTANT INFORMATION REGARDING THE COMPANY
Information about the ING Life Insurance and Annuity Company found in your prospectus and/or Statement of
Additional Information is deleted and replaced with the following:
ING Life Insurance and Annuity Company (the “Company,” “we,” “us,” “our”) issues the contracts described in this
prospectus and is responsible for providing each contract’s insurance and annuity benefits. All guarantees and benefits
provided under the contracts that are not related to the separate account are subject to the claims paying ability of the
Company and our general account.
We are a stock life insurance company organized under the insurance laws of the State of Connecticut in 1976. Until May
7, 2013, we were a wholly owned indirect subsidiary of ING Groep N.V. (“ING”), a global financial institution active in
the fields of insurance, banking and asset management. Through a merger, our operations include the business of Aetna
Variable Annuity Life Insurance Company (formerly known as Participating Annuity Life Insurance Company, an
Arkansas life insurance company organized in 1954). Prior to January 1, 2002, the Company was known as Aetna Life
Insurance and Annuity Company.
Pursuant to an agreement with the European Commission (“EC”), ING has agreed to divest itself of ING U.S., Inc. and its
subsidiaries, including the Company (collectively “ING U.S.”), which constitutes ING’s U.S.-based retirement, investment
management and insurance operations. To effect this divestment, on May 7, 2013 ING completed an initial public offering
(“IPO”) of the common stock of ING U.S. While ING is currently the majority shareholder of the common stock of ING
U.S., pursuant to the agreement with the EC mentioned above ING is required to divest itself of at least 25% of ING U.S.
by the end of 2013, more than 50% by the end of 2014 and 100% by the end of 2016.
