What is "escheatment" and when does it take place?

Escheatment is the process by which abandoned or unclaimed property is transferred to a state, making the state the legal owner of the property. A stock account can be deemed abandoned by inactivity due to an incorrect mailing address, uncashed dividend checks, or no direct contact by the stockholder for a specified period of time. Each state has its own escheatment laws, with inactivity or dormancy periods ranging from three to five years. The laws apply to all inactive stock accounts – whether owned by U.S. or foreign stockholders, including those enrolled in dividend reinvestment plans or direct deposit of dividend payments or holding paper stock certificates. Before any property is transferred to a state, all companies are required to perform a due diligence search for owners of property at risk of escheatment.

How can I prevent my stock account from being escheated to the state?

You must keep your stock account active. Do this by: keeping your address current and correct, voting your proxy, cashing or depositing all dividend checks, and responding to any due diligence mailings from our transfer agent. For more tips, click here.

I am enrolled in the dividend reinvestment plan, so why was my stock escheated?

Several states confirmed that dividend reinvestment may not constitute "direct" contact by a stockholder. So even if there is a good address on the account, if there has been no other account activity (for example, sale or purchase of shares — but not dividend reinvestment — or an address change or response to a due diligence mailing) during the dormancy period governed by the state, the stock account may be considered to be inactive or dormant by the state. As such, the property is then escheated to the state according to its specific laws.

How can I find out if I have any escheated property? How can I recover any escheated property?

Go to to start your search. Foreign stockholders should search in the State of Delaware. To make a claim, follow the instructions provided by each state.
