Item 8.01 Other Events.

On May 27, 2011, AMERIGROUP Corporation ("the Company") entered into a trading plan in accordance with Rule 10b5-1 of the Securities Exchange Act of 1934, as amended (the "Act"), to facilitate repurchases of its common stock (the "Rule 10b5-1 plan"). The Rule 10b5-1 plan will effectively terminate the previous Rule 10b5-1 plan and become effective on August 2, 2011 and expire on August 2, 2013, unless terminated earlier in accordance with its terms. Repurchases may occur pursuant to the Rule 10b5-1 plan until the Company has repurchased shares of its common stock equal to $140 million. The Company may also repurchase shares authorized under its stock repurchase program, if at all, through open market purchases in accordance with Rule 10b-18 of the Act or pursuant to additional Rule 10b5-1 plans. The number of shares to be repurchased and the timing of the repurchases will be based on the level of available cash and other factors, including market conditions, the terms of any applicable 10b5-1 plans and self-imposed blackout periods.

The Rule 10b5-1 plan allows the Company to execute trades during periods when it would ordinarily not be permitted to do so because it may be in possession of material non-public information, because of insider trading laws or due to self-imposed trading blackout periods. A broker chosen by the Company will have the authority, under the prices, terms and limitations set forth in the Rule 10b5-1 plan, including compliance with Rule 10b-18 of the Act, to repurchase shares on the Company's behalf. Because the repurchases under the Rule 10b5-1 plan will be triggered by certain share prices, there is no guarantee as to the exact number of shares that will be repurchased under the Rule 10b5-1 plan, or that there will be any repurchases at all pursuant to the Rule 10b5-1 plan.


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.
