Ann: Investor Presentation, page-6

Hey Delta - thanks. I tried Google like you suggested. Here's a great example (not mine, on google):

"Bookings are not a GAAP defined term, and thus, the definition might vary by company. Typically, bookings correspond to the value of a contract signed during a certain period. Where this gets tricky is making sure that whatever data you are reporting for bookings is apples to apples. It’s not a good idea, and it is also very misleading, to combine the value of a 12-month contract with a 24 month contract booked in the same period and report the sum of the two contracts as your company’s bookings for that period. Even if you have booked a multi-year deal, the amount that your company reports for bookings in that period should typically be limited to the value of the first 12 months of the contract."
