The article 'Ultimatum on Mui Wo ferries' on page C1 yesterday, incorrectly said that Peng Chau Kaito, which runs the ferry service between Discovery Bay and Mui Wo, will see its licence expire by August 9, 2012. The correct date is August 9, 2013. Until then, any plans to reduce or stop the service must be approved by the government. However, if the Transport Department approves Peng Chau Kaito's proposal to cut the number of trips, it will take effect on September 3 at the earliest.
