A company's past year Annual Loss Expectancy (ALE) for a particular vulnerability was $50,000. New security measures were put in place which brought the current year's ALE down to $30,000.

RTO and RPO are different name for the same thing - the time until an operation is made available after a disaster. RPO is not critical to the restoration of business functions while RTO is critical in that it affects the amount of data and transactions lost during a disaster.
