Powers grew impatient and established the reparation sum at 226 billion gold marks. The Germans countered with an offer of 30 billion. On 24 April 1921, the German Government wrote to the American Government expressing "her readiness to acknowledge for reparation purposes a total liability of 50 billion gold marks", but was also prepared "to pay the equivalent of this sum in annuities adapted to her economic capacity totalling 200 billion gold marks". In addition, the German Government stated that "to accelerate the redemption of the balance" and "to combat misery and hatred created by the war", Germany was willing to provide the resources needed and "to undertake herself the rebuilding of townships, villages, and hamlets". London Schedule of Payments The London Schedule of Payments of 5 May 1921 established "the full liability of all the Central Powers combined, not just Germany alone," at gold marks. This sum was a compromise promoted by Belgiumagainst higher figures demanded by the French and Italians and the lower figure the British supportedthat "represented an assessment of the lowest amount that public opinion ... would tolerate". This figure was divided into three series of bonds: "A" and "B" Bonds together had a nominal value of gold marks less than the sum Germany had previously offered to pay. "C" Bonds, comprising the remainder of the reparation figure, "were deliberately designed to be chimerical." They were "a political bargaining chip" that served the domestic policies of France and the United Kingdom. The figure was completely unreal; its primary function was to mislead public opinion "into believing that the 132-billion-mark figure was being maintained". Furthermore, "Allied experts knew that Germany could not pay 132 billion marks and that the other Central Powers could pay little. Thus, the A and B Bonds, which were genuine, represented the actual Allied assessment of German capacity to pay." Taking into account the sum already paid between 1919 and 1921, Germany's immediate obligation was 41 billion gold marks. To pay towards this sum, Germany could pay in kind or in cash. Commodities paid in kind included coal, timber, chemical dyes, pharmaceuticals, livestock, agricultural machines, construction materials, and factory machinery. The gold value of these would be deducted from what Germany was required to pay. Germany's assistance with the restoration of the university library of Louvain, which was destroyed by the Germans on 25 August 1914, was also credited towards the sum, as
