This article talks about a financial fraud which didn’t receive much coverage in the main stream media. Some more coverage can be found here. I have covered the functioning of an RTA in my other article here. However RTA can in general also provide service to companies instead of just mutual funds discussed in the article.
Shares/dividends can remain unclaimed because the initial owner might have died and his family might not have been aware of this; or forgotten; or the ownership documents might have been lost and the owner didn’t want to perceive it because of cost benefit analysis. At times the owner might decide against putting effort to en cash a small dividend.
When a fraudster becomes aware (usually with the help of employees of RTA) of any unclaimed shares/dividends lying around for a long period of time he produces fake documents and claims himself to be the rightful owner. As long as the rightful owners are not aware of this and don’t approach the company there is very little chance of catching these rightful owners. The only way is to put stricter norms for claiming the shares.
