such that ??

such that 在題中句子確是有點不尋常，最常見 such that 有兩種用法。

1. 指出後果 (consequence)
Examples:
The layout of the building is such that all the facilities are easily accessible.
The party must be well organized such that every guest will feel at home.

such that 中文意思是「這般 ... 就...」
such that 可與 in such a way that 互通。

2. 指出條件 (condition)
You can withdraw more money than you have in your account such that you do not exceed your credit limit.

such that 可解為 to the extent that, subject to the condition that

such that 不是指示代名詞。

講番題目，為方便解釋，原句可讀成
The lessee has the option to purchase the asset ... such that ... it is reasonably certain that the option will be exercised

such that 後的分句不是後果也不是條件，而是假設。因此 such that 在句中意思是 under the assumption that，such that 用作指出原因是較罕見，所以我說是不尋常。

原句本來就是個「捉字虱」的句子，中文翻譯如下：

貸借人有權在期權可行使日以預計會低於公平價值的價格購買資產，基於貸借人在租約確立的初期合理地確信該期權會被行使。

在可行使日資產是甚麼價格，期權會否被行使，句中都沒有確認。
