Pretty much as described by Fawcett. Congratulations letter, acceptance forms, information, administrative stuff.
From my quick glance through these materials: The fellowship consists of a one-time payment of about 40% of the total amount for travel and first three months' maintenance, with the rest to be disbursed every three months or so. I cannot figure out how they calculated the fellowship amount. It might be a combination of expenses plus maintenance allowance; it might be standard amount by region, number of dependents, whatever; or it might be a percentage (nearly 100%) of the maintenance allowance. Health insurance is paid separately directly to the insurer.
