Contribution to the loss

How do you know your contribution figures are right?

• They each come out below 100 points
• They add up to the book's total return
• The biggest sleeve has the biggest contribution

A carry sleeve earned interest during a quarter in which the book lost money. What sign is its share of the loss?

• Negative, because it offset part of the loss
• Positive, like every other sleeve
• Zero, because carry isn't part of the loss
