Ought we be worried?

[ramAnag]

its not exactly a clear expression! - and hardly likely to be anything you would do whilst thinking about your ex!

FYI RA (although I doubt you have the "I") cum ex schemes have been going on all over Europe in recent years costing various treasuries (not ours) billions. Its keyed off a legal loophole allowing multiple parties to claim ownership of a share, and so its dividend, and thus all of them claim a tax refund on the dividend, even though the tax was only paid to the exchequer once by the company.

Also known as dividend arbitrage

I wasn’t doubting you, GP...just seemed like a, faintly rude, foreign language. Accountancy speak and dividend fraud(?) is another world to me...and frankly one we’d all be better off without perhaps.
