is notes payable included in EV calculation?

According to a CFAI practice question (Metiu Metev Case Scenario) it is not part of the EV, but isn’t note payable a financial liability and needs to be included?

EV = (MV Equity + MV Long Term Debt + MV Preferred Stock + Non Controlling Interest) - (Cash & Cash Equivalents + Marketable Securites)

So only the long term debt?

Yes only debts. Debt is a subset of liabilities. You don’t add all kinds of liabilities
