1. A natural or legal person may enter into a short sale of a share admitted to trading on a trading venue only where one of the following conditions is fulfilled:

(a) the natural or legal person has borrowed the share or has made alternative provisions resulting in a similar legal effect;

(b) the natural or legal person has entered into an agreement to borrow the share or has another absolutely enforceable claim under contract or property law to be transferred ownership of a corresponding number of securities of the same class so that settlement can be effected when it is due;

(c) the natural or legal person has an arrangement with a third party under which that third party has confirmed that the share has been located and has taken measures vis-à-vis third parties necessary for the natural or legal person to have a reasonable expectation that settlement can be effected when it is due.

2. For the purposes of paragraph 1, the FCA may make implementing technical standards to determine the types of agreements, arrangements and measures that adequately ensure that the share will be available for settlement. In determining what measures are necessary to have a reasonable expectation that settlement can be effected when it is due, the FCA shall take into account, inter alia, the intraday trading and the liquidity of the shares.
