Calculating FCF/NI Conversion Ratio

Hello,

Thanks in advance for the help! Im calculating FCF/NI conversion ratios for several companies. Some companies have minority interest while others do not. When I calculate my ratio, do I want to use NI from continuing operations or NI attributable to common? The NI attributable to common will be after the minority interest deduction. So as to evolve from my minion status, any explanation would be helpful.

I was looking at Honeywell's quarterly slide and they calculate their FCF/NI conversion ration on NI to attributable to common. Since the P&L is consolidated, this makes logically sense to me.

Thanks,
