If competitors agree to adjust prices or charge the same or similar prices, they are guilty of cartel action.

Companies competing on the same tender should not collude to decide who should 'win' the tender.

Competitors must not carve up the market among themselves.

The penalty for companies or organisations found guilty of anti-competitive practices could be a fine of up to 10 per cent of their annual turnover in Singapore for each year of infringement, for up to three years.
