Social Responsibilities

No debt management

In order to run a sustainable  business, a corporation requires continuous profit funds instead of bank loan as turnover funds. Bank loans as turnover funds have risks that highly depend on the current world economy, which can then  determine a company’s fate. High financial leverage, blind investment, and poor decision making may cause the company to go bankrupt. Hence, “No debt management” is a company’s only viable motto, and also the company’s obligation towards their shareholders, employees, and society. Our motto was adopted from Toyota, Japan.
