My amateur 2c - Yes brackets are negatives, so liabilities on balance sheet, typically creditors. Problem with micro accounts is you don't get an income statement - all you see is the shareholder deficit/surplus which is the amount retained in the business. In this case it's dropping, to me that's not a good sign, I forget the rule's on dividends but it's unlikely to be running a big profit and pulling out a load of dividends.
The (13,088) means the liabilities outweigh the assets.
It's may not entirely a bad, if say it doubled and doubled it's sales again growing it's brand. But a company lives and dies on its cash flow an this sound like it has little.
I stand ready to be corrected. ;-)
