Coles Group (ASX:COL) is required to pay the Australian Competition and Consumer Commission's (ACCC) phase two review fee for the proposed leasehold interest acquisition of a Western Australia supermarket and liquor site in Somerville by Feb. 9 if it wishes to continue with the review, according to a notification from the regulator.

In November last year, the supermarket giant lodged a notification with the ACCC regarding Coles Supermarkets Australia's proposed acquisition. The ACCC decided late last month that the acquisition be subject to a phase two review after determining that the deal could lead to a substantial lessening of competition in a market.

If the fee is not paid by Feb. 9, the ACCC will cease considering the notification. The determination period will end on June 12.

Coles' shares fell nearly 1% in recent trading on Friday.
