Recently, a anonymous person emailed me a written spreadsheet which indicated how profits from seminars are compensated. I am guessing that this would apply for major functions, where tens of thousands may attend, and millions of dollars collected to more regional types of meetings where thousand of dollars are up for grabs.
Basically, the income is derived by adding up the collections for IBOs and guests, and subtracting the expenses. That becomes the net income. The LOS then takes 10% off the top of the net profit. After that, it appears that the remaining profit is distributed to the host couple and speakers. The spreadsheet says in bold "Speaker is paid last".
Thus if a function had 10,000 IBOs and guests, and they all paid $100 to attend. The gross is 1,000,000. Say the expenses to run such a function were $100,000, then net is $900,000.
The LOS gets $90,000 and the rest is spread amongst the host couple and the speakers (I presume). So if a function has 5 speakers, they would all get $162,000 for a speaking engagement. (Average diamond income reported by Amway = $146,900)
So we can conclude, based on this evidence, that an "average" diamond could conceivably make more money from one (1) major function han this Amway business makes in a year.
Some of this of course, is my speculation, but you can observe a function and massage the numbers based on the formula given here.
