English to French Other Law: Contract(s) memorandum of association - shares

Hello,

In a Memorandum of Association, under the "shares, authorized capital and capital" section comes this sentence:

Upon the issue by the Company of a share without par value, the consideration in respect of the share constitutes capital to the extent designated by the directors and the excess constitutes surplus, except that the directors must designate as capital an amount of the consideration that is at least equal to the amount that the share is entitled to as a preference, if any, in the assets of the Company upon liquidation of the Company.

What I don't get is the "the consideration that is at least equal to the amount that the share is entitled to as a preference, if any, in the assets of the Company" part.

What would be the preference for a share in this case ?

Thanks for your help!!
