The Agreement between the Allied and Associated Powers with Regard to the Contribution to the Cost of Liberation of the Territories of the Former Austro-Hungarian Monarchy was concluded on 10 September 1919 and complemented the Saint-Germain peace treaty with Austria. The treaty was registered in the League of Nations Treaty Series on 21 October 1920. The agreement was modified by a declaration issued by the signatory parties on 8 December 1919, which allowed the Italian government to issue bonds over a longer period of time to pay off its debts.
