Italian to English Bus/Financial Finance (general)

I never touch financial texts but my best client has begged me to do a short letter as a last resort. My only problem is this word "closing", as in:
“closing con le banche finanziatrici”
“closing dell’operazione di finanziamento”
"finanziamento delle Banche in project financing (closing) di XXX"

Although there are quite a few web hits for “closing with the banks” and “closing the funding” (some of which may be translations), these are not terms I have ever heard and should be most grateful for some expert advice.
