         answer: |
-          If you’re an EA customer, `PAYGPrice` is populated only for first party Azure usage charges where `PricingModel` is `OnDemand`. `PAYGprice` isn't populated when `PricingModel = Reservations`, `Spot`, `Marketplace`, or `SavingsPlan`.

       - question: Does Usage Details have Reservation charges?
         answer: |
           Yes it does. You can see those charges according to when the actual charges occurred (Actual Cost) or you can see the charges spread across the resources that consumed the Reservation (Amortized Cost). For more information, see [Get amortized costs](costs/manage-automation.md#get-amortized-cost-details).
