The Court of Appeal then considered whether the retroactivity of this transaction, assuming that the FDIC/Weatherford transaction was retroactive (which it was not), had a legal effect on the transaction between FDIC and FH Partners. FH Partners could not “rely on the thesis that a retroactive effective date in a contract can be interpreted in such a way as to have an automatic retroactive effect on a separate contract”, which would probably have been fatal in its case. However, the language of the FDIC/FH Partners agreements continued to scuttle FH Partners` arguments, because the documents (1) stated that they could only be amended or cancelled in a letter signed by the parties; (2) did not expect FDIC to be able to change what it communicated to FH Partners after the conclusion (3) transferred FDIC`s interests “from the closing date of the loan sale”, (4) entrusted FDIC`s participation in the loan “as planned”, provided that FDIC “is not required to secure or obtain a missing interim contract or assignment to [FDIC] that is not included in the loan file”, (6) provides for a procedure where FH Partners could request FDIC to redeem a loan if it was found that FDIC was not the owner at the time of closing and (7) transferred FDIC`s rights “at the time of closing”. The “effective date” clause sounds pretty simple, but you need to be careful not to just pass it through your agreement. Read the full confidentiality agreement and think about what logically cannot be applied on the retroactive effectiveness date. But retrodating (or adding a retroactive date) of a contract can be a difficult affair, perhaps even more so for NDA agreements because of their nature and content. As Ken Adams indicated, if you want a contract to cover activities before it is signed, you can simply say it: this agreement applies to transactions between the parties on or after xxxx. Do not put yourself according to the effective date of the contract. A possible catch in signing a demoted agreement is the potential for breach of the signing. While adding a retroactive date to a legal agreement isn`t unusual, you need to make sure that after weeks of cooperative negotiations, discussions, or partnerships, you won`t walk out of the left pack with a retroactive NDA in hand. .
