@mips_tux question is not something that necessarily Jolla should answer. Anyone that is a legal expert of the companies law in Finland can answer the question. That answer is going to apply also to Jolla Oy, no matter what they answer or not.
Therefore, the above question is seeking an answer but not necessarily by Jolla Oy and that answer by the Finnish law will be enough for us to know the next deadline.
Instead, the answer of @eson is not enough because it is based on a supposition that Finnish limited liability private companies undergo under the same law terms of the Germany or England companies
I can grant you that Germany law and English law about that kind of companies is pretty different, in fact. Occasionally, some similitude apply and some time terms can be similar but because every country considers the solar year as a fiscal year.
