Each month, we calculate the Administrative Services Fee by applying a Monthly Periodic Rate to the Average Daily Value of the precious metals in your account. Additionally, the Monthly Periodic Rate is 1/12th of the Annual Rate. Every day, we determine the value of your account by multiplying the number of ounces of precious metals by the Daily London PM Fix price of bullion per ounce. At the end of the month, we calculate the Average Daily Value by adding the Daily Values for each day of the period and dividing by the number of days in that period.
