Agere will sell the 25 shares for me at whatever the market rate is, and will charge me a mere $2.50 per share processing fee up to a maximum of $40. (Market price is about $12.00/share.) And they warn that your broker might also assess a fee for you to participate in this--last such charge I had was $50. So I can get rid of the 25 shares of Agere for $90 in fees, almost 1/3 of what the sale will generate.
On the other hand, I can just sell these myself for a flat fee of $9.95 at the discount broker.
(OK, OK, buyout offers are aimed at those who use full-service brokers, and the $90 might look like a bargain to them. I just read the terms for the amusement value, and discard.)
