Restrictions on transferability of shares

Luxembourg
Private limited liability company (Société à responsabilité limitée or S.à r.l.)
A transfer or issuance of shares to a non-shareholder must be approved by the shareholders representing at least 3/4 of the share capital given at a shareholders’ meeting. The articles of incorporation/association may lower this threshold up to the favorable votes of the shareholders representing at least half of the share capital.
Further to the reform, in the absence of consent from the shareholders, the shares can be acquired, with the transferring shareholder's consent, by (i) the other shareholders, (ii) a third party approved by them or (iii) the company itself, within a period of 3 months, which may be extended to 6 months under certain conditions. The applicable conditions to determine the transfer price of the shares should be set out in the articles of incorporation/association, failing which if the parties cannot reach an agreement, the price will be determined by the competent Luxembourg court.
If the shares are not acquired in accordance with the aforementioned provisions, the shareholder may proceed with the initially proposed transfer. This represents a significant change to the previous rules under which shareholders of a S.à r.l. that wished to transfer their shares were unable to do so if they failed to obtain the requisite consent. It is however, still possible to provide for transfer restrictions in eg, a shareholders' agreement.
Public limited liability company (Société anonyme or S.A.)
The shares issued by an S.A. are freely transferable. The articles of incorporation/association of the company, or a shareholders’ agreement, may provide for certain restrictions, within the limits of the Luxembourg law of 10 August 1915 on commercial companies, as amended from time to time.
Special limited partnership (Société en commandite spéciale or SCSp)
The limited partnership agreement should provide for the conditions at which the limited partnership interests or units issued by an SCSp may be transferred, dismembered (démembrées) or pledged. Unless otherwise provided in the limited partnership agreement, any transfer other than because of death, dismemberment of ownership (démembrement) or pledge of limited partnership interests requires the unanimous consent of the general partner(s).
The limited partnership agreement should provide for the conditions at which the general partnership interests or units issued by an SCSp may be transferred, dismembered (démembrées) or pledged. Unless otherwise provided in the limited partnership agreement, any transfer other than because of death, dismemberment of ownership (démembrement) or pledge of general partnership interests requires the consent of the partners deciding in the same manner as for the amendment of the limited partnership agreement.
