Increasingly, it is the board of directors and CEO that are held accountable by the shareholders and the public in the event of an information security incident. So they deserve to be opportunity to make the key security decisions after being briefed on the company’s security posture and threat landscape directly from the most senior security expert in the company and having the opportunity to question this expert.
This reporting structure gives the CISO access to the business leaders so that they can better ensure that the security strategies are aligned with business strategies.

Also, this takes him/her out of the "business is all that matters" approach that often happens at companies. I've seen it on multiple occasions where marketing or another business unit wants a new piece of tech or access to data asap (controls be darned) and if the ISO is reporting to the CEO or CIO they get trumped.
