Appropriate adjective and adverb

All applications are subject to the bank’s final decision, at its absolute discretion. The bank shall be entitled to reject any such application(s) at any time and from time to time without reason(s) assigning therefore and without liability to the Applicants.

The above two adjoining sentences have been picked up from a bank’s website. Anyone carefully reading them will find that the participle “assigning” and the adverb “therefore” do not appear to have been appropriately used in the second sentence. The former should have been “assigned” and the latter, “therefor”.

Hence, the second sentence should read, “The bank shall be entitled to reject any such application(s) at any time and from time to time without reason(s) assigned therefor and without liability to the Applicants.”
