Foreign dividends sometimes lag a few days, especially if there are fees and taxes. In this case, the last date I've seen is June 18 for US investors.
I think they only pay once a year, so this dividend refers to the financial results of 2012. The pundits keep saying it's all worth it and DT will demonstrate its greatness. The total return has not worked for me, since I came in at $17.76. Good dividend rate, especially at this level. I don't think I'll be with them another full year.
