From his Facebook page: Final note for tonight. Let me clarify the IBF situation. At weighin I was informed Id be stripped of my IBF if I didnt defend it within 90 days vs their Mandatory. In addition, they were charging me $42,000 for a belt I never received. Yep, u heard that right....I never got my IBF belt. The belt I walked in with was my 112lb belt from Darchinyan. So instead of getting stripped, I relinquished it.
So much for unifying the titles. Anyways, that's the problem with holding all the belts. If you want to keep them all, you have an obligation to defend meaningless mandatories.
