Therefore, traditional prudence always suggests that a company must have enough cash to cover its immediate obligations. However, there is a growing breed of FMCG companies that claim otherwise. Unlike most other industries, the turnover of a consumer goods business is not limited by its ability to produce, but by its sales capacity. They can generate cash so quickly that they actually have negative working capital. This happens because customers pay in advance and so quickly, the business has no problem raising cash (like Nestlé, Britannia). In these companies the products are delivered and sold to the customer before the company even pays them. Negative working capital is a sign of management efficiency in a business with low inventory and accounts receivable (which means it operates on a nearly strictly cash basis). In another situation, it is a sign that a company may be facing bankruptcy or serious financial problems.
