Redeemable preference shares promise a fixed date or trigger when the company must buy them back at a pre-agreed price.

PPM is “parts per million,” a mass or volume ratio of one substance in a million parts of another.

Personal Ethics: the private compass of values that guides an individual’s choices, regardless of where they work.
