re-striking.

That definition allows to understand the restructured swap by replacing 3M Libor with SARON 3M1. In this case, the principal amount remains CHF 10 million; the agent in question pays a 2.5% fixed rate per year; in exchange, he receives a three months Swiss Average Rate Overnight, instead of Libor 3 months.

the floor is a strike because it allows the agent in question to pay back the annual, fixed interest rate (2.5%). So my translation is correct given the parenthesis (prix d'exercice, strike).

The text submitted by Asker does not mention a change in the fixed rate as the result of the restructured swap

As you say, a swap is a contract. Whether "the agent" decides to protect themselves with a cap, a floor, or Captain America' shield doesn't "restructure" (= modify) such contract, i.e. change the LIBOR for the SARON and "consequently re-strike the fix rate". If you need to "assume" anything, why wouldn't you assume that there might be an adjustment of the fix rate to cover any spread arising from the method/type of conversion? Take a look at this source, for example: http://assets.isda.org/media/04d213b6/db0b0fd7-pdf/

Par ailleurs, du seul point de vue de la traduction, vous voyez une proximité quelconque entre "re-strike the fix rate" et "acheter un second taux plancher" - which back-translates to "buy a second [rate] floor" ?

An interest rate swap is a forward contract in which one stream of future interest payments is exchanged for another based on a specified principal amount. Interest rate swaps usually involve the exchange of a fixed interest rate for a floating rate, or vice versa, to reduce or increase exposure to fluctuations in interest rates or to obtain a marginally lower interest rate than would have been possible without the swap.

That definition allows to understand the restructured swap by replacing 3M Libor with SARON 3M1. In this case, the principal amount remains CHF 10 million; the agent in question pays a 2.5% fixed rate per year; in exchange, he receives a three months Swiss Average Rate Overnight, instead of Libor 3 months.

As the agent's return rates are risky (based in both cases on a floating rate), the agent must protect him/herself. What does he do? He/she buys a floor rate on the OTC (over the counter). This fixed rate will protect the agent in question from the gyrations of floating rates (Libor and SARON).

This is the reason why my translation assumes that the agent buys a floor twice.

Je comprends que "Vous détenez un swap de 10 millions de francs suisses d’une [teneur][échéance] résiduelle de 10 ans pour lequel vous payez un taux fixe (2,50%) et recevez le LIBOR [à trois mois][3M]. Vous avez donc restructuré le swap en remplaçant le LIBOR [à 3 mois][3M] par le SARON [à 3 mois (bis)] [3M1] et en conséquence, vous [ré-établissez] [redéfinissez] [renégociez] [réviser] le taux fixe."
