Thank you. The only IOC I know of is the International Olympic Committee.

Or if you work in trading, IOC made it a very confusing title

I'm a programmer, designer and architect, so my mind immediately went to "Inversion of Control"

Or Input/Output Controller (scientific facility control layer tech)

It is delightful how acronyms close to you embed deeply and can cause little shocks vs the rest of the world.
