The Twenty-fifth Meeting of the Executive
Committee decided that contributing parties which issued promissory notes in currencies other than the United States dollar should be responsible for
the upward or downward movement of the value of their promissory notes due to
exchange rate fluctuations. The variance between the value of the note when it
was deposited and the value of the note when it was cashed should be credited
or debited to the account of the note-issuing party and reflected
in the contribution due from the party in the following year.
