Not sure I understand the question, but worth a shot:
Values to your organisation, just three for starters ...
1. Increased customer confidence in your ability to securely manage/process/handle/store their valuable data. Protecting your valuable data from competitors, hackers, terrorists, journalists etc.
2. Effective controls against data leaks or breaches, many of which carry company-damaging and reputation-shattering huge fines and negative publicity
3. Helping your organisation win business in competitive situations. I do not waste time on companies who have not implemented an ISMS.
