PLEASE

I have been tasked (For work) to take on a challenge with our CFO. I have googled and read just about everything I can, and I am still stumped.

In vivid and descriptive detail (Please think of it like explaining to a toddler) can you help me understand:

What is the:

1. Gross working capital
2. Net working capital
3. Net operating working capital
4. Cash conversion cycle

Then: Analyze the differences between gross working capital, net working capital, and net operating working capital AND their relationship to the cash conversion cycle.

And please, I can't figure out, is there such a thing as "Operating working capital" AND "Net operating working capital"? or are these the same thing?

Thank you SOOOO much
