Penultimate Prize Winners

On Who Wants to Be a Millionaire?, if a Top Prize Winner is a contestant who wins the top prize by answering all 15 questions correctly (usually 1 million units of the local currency), then a penultimate prize winner is a contestant who wins the second-biggest prize (usually 500,000 units of the local currency), by answering the first 14 questions correctly, and then walking away from the 15th and final question.
