-- or --
Pronunciation: 'in-t&r-"kOrs, -"kors

2 : exchange especially of thoughts or feelings : COMMUNION
The word has also been defined as "..business.."; which may be most correct in this instance, considering who is giving what to whom - and the myriad of possible reasons why.
Good luck with your T-A system's prognostications on ENGY speculation.
