Below is a portion of the summary report on the hostage crisis in Iran.

The revised US response was given to the Algerians on December 30. In this formulation we offered a detailed proposal for settling claims through arbitration and the establishment of an escrow account in an agreed central bank for the deposit of presently frozen Iranian assets. Part of the proposal called for establishment by Iran of a Security Account with the same central bank to provide a means of making payment of claims under the proposed Claims Settlement Agreement. The proposals were worked out as a Declaration of the Government of Algeria which both sides would accept. When these arrangements were all in place and when Algeria certified that the 52 hostages had been safely released, the monies in the escrow account could be released to Iran but the Security Account would be maintained by Iran with a large balance during the settlement of claims. With the assurance of an acceptable agreement on arbitration of claims, the US would seek to have the courts lift attachment orders affecting frozen assets so that those funds could also be placed in the escrow account. We explained that it would take time beyond the release of the hostages for these legal actions to be accomplished.
