The “act as one” clause is found in reinsurance contracts, a clause that is included to avoid the situation where several reinsurers are parties to the same dispute and each wants to appoint their own arbitrator. The “act as one” clause obliges reinsurers to act in concert in selecting an arbitration panel, as well as in all major communications and decisions relating to the dispute. It leaves reinsurers free to assert their own claims or objections, and this does not detract from several obligations that normally exist under most reinsurance contracts. This allows the arbitration process to move forward without confusion about how many arbitrators the parties to the dispute will appoint. In effect, it treats the reinsurer as one party (which it is) and the reinsurers as one party when more than one reinsurer is involved in a dispute. Thus, each of the two “parties” or parties may appoint one arbitrator, and the arbitrators appointed by the parties may appoint a judge, fulfilling the contractual requirement for a panel of three arbitrators.
