Do i have to send a royalty report even if i am not making enough profit?

According to EULA :

“no royalty is owed on the following forms of revenue:
The first $3,000.00 in gross revenue for each Product per calendar quarter;”

so lets say we informed epic about our game and in the first quarter of a year we made a profit of 2800$, do we then have to send a report indicating that we didn’t make an earning ? or that the royalty fee is zero ?
What if the game is for free do i have to send each quarter a year for the rest of my life indicating that gross revenue is zero and thus royalty fee is zero ?

why isn’t this situations described in EULA ?

Thanks and best regards.

Per the EULA:

Within 45 days after the end of each calendar quarter in which a Product earns revenue outside of the above-listed royalty exclusions, you will pay to Epic the full amount of the royalty due for such quarter and send Epic a royalty report on a per Product basis.

Therefore, if the game earns $2800 in a quarter, then the Product does not earn revenue outside of the royalty exclusions. If that is the case, there is no obligation to send a royalty report.
