12. Concentrations and Credit Risk	12. Concentrations and Credit Risk The Company operates principally in Hong Kong and grants credit to its customers in this geographic region. Hong Kong has a relatively stable economy. However, it is always possible that unanticipated events in foreign countries could disrupt the Company's operations. Financial instruments that potentially subject the Group to a concentration of credit risk consist of cash and accounts receivable. The Company does not require collateral to support financial instruments that are subject to credit risk.

The entire disclosure for any concentrations existing at the date of the financial statements that make an entity vulnerable to a reasonably possible, near-term, severe impact. This disclosure informs financial statement users about the general nature of the risk associated with the concentration, and may indicate the percentage of concentration risk as of the balance sheet date.
