I have a small quantity of shares in Aviva PLC. I have no clear idea why I have them, I believe they evolved from an ancient school prize for reading a book or something else. In about 1973, I was given perhaps 50p in a building society account. Multiple unfathonable take-overs later, and by 2009 I end up with a bunch of shares in Aviva which pay me about £10 a year in dividends. Big deal you say.
Now they want to know if I want to enrol in a "scrip dividend" which is they give me more shares, instead of a few pounds annual dividend.
This is a toy quantity of money, and I have utterly no opinion good or bad about Aviva, I'm prepared to consider any viewpoint. So is it sign up for a scrip dividend, or let then continue to send me a very small cheque now and then?
