 In addition to assisting clients with recurring activities, Temmes has substantial experience with cross-border acquisitions, mergers, divestitures, migrations and restructuring transactions.  We are also very familiar with global cash management and assist many of our clients with cash pooling, intercompany netting and related techniques.

Temmes serves clients in all major industry segments and they range from privately-held companies that are expanding internationally for the first time to portfolio companies of private equity firms to publicly-held companies, a number of which are included in the Fortune 500.
