Item 8.01 Other Events.

On September 14, 2016, David M. Cordani, President and Chief Executive Officer of Cigna Corporation ("Cigna" or the "Company"), adopted a stock trading plan designed to comply with Rule 10b5-1 of the Securities Exchange Act of 1934, as amended. Under Rule 10b5-1, officers, directors and other individuals who are not in possession of material non-public information may adopt a pre-arranged plan or contract for transactions in company securities under specified conditions and at specified times. Using these 10b5-1 plans, individuals can diversify their investment portfolios for financial planning purposes, plan for charitable giving, spread stock trades over an extended period of time to reduce market impact and avoid concerns about transactions occurring at a time when they might possess material non-public information. In accordance with Rule 10b5-1, Mr. Cordani will not have subsequent discretion over the transactions under his plan.

Mr. Cordani's plan provides for transactions to occur during specified periods between November 2016 and March 2017. The plan provides for the sale of shares he may receive pursuant to Cigna's strategic performance share program following the completion of the 2014–2016 performance period and the gift of wholly-owned shares to a charitable foundation. Transactions under Mr. Cordani's plan may occur on the open market at prevailing market prices or subject to minimum price thresholds specified in the plan.

Mr. Cordani continues to be subject to the Company's executive stock ownership guidelines, under which he is required to hold Cigna stock and stock equivalents valued at least six-times his base salary. Mr. Cordani does not expect the plan to materially change his ownership position.

Transactions under Mr. Cordani's plan will be reported to the Securities and Exchange Commission in accordance with applicable securities laws, rules and regulations. The Company does not undertake to report 10b5-1 plans that may be adopted by any officers or directors in the future, or to report any modification or termination of any trading plan, whether or not the plan was publicly announced, except to the extent required by law.


Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
