Sanli Environmental's (SGX:1E3) subsidiary, Sanli M&E Engineering, received a letter from a customer, in connection with damages due to delays in the completion of certain phases of a project, according to a Monday filing with the Singapore Exchange.

The subsidiary had previously submitted applications for extension of time for the project, to which it is yet to receive a response.

To date, the parties have not agreed on any liquidated damages, with the company currently not in a position to determine the financial implications of the delays.
