Yearly Payout Threshold

Does the payout threshold have to be met by the end of the calendar year? We only started publishing maps in September and assumed that the payout threshold was calculated from when we signed up or published our first map.

Now that we see our first payout information for September it says we have 60 days remaining to reach the payout threshold. Does this mean that we will forfeit what we have made in September and October at the end of this year since November and December earnings will only apply from next year?

If anyone can help, it would be greatly appreciated.
