offhand attack damage bonus question

[SirKillalot]

Making an attack with an offhand weapon grants a damage bonus equal to 1/2 strength modifier.

But say I get ánd strength mod bonus, ánd dex mod bonus ánd int mod bonus on damage on every hit. Do they all get halved for the offhand attack? Or just the strength mod bonus?

The way I read it I only need to halve the strength mod bonus...

Thanks!

Just the Strength mod. The rest are other bonuses that have nothing to do with off-hand or not off-hand.
