"CIBC said net income climbed to $794-million, or $1.90 a share, from $500-million, or $1.17 a share.
Revenue was little changed from the year-ago period but the bank said that its income-tax expense plunged to $249-million from $742-million."

Can someone please explain what would cause the income tax expense to drop so dramatically?
