Title:
Economy_of_Greece

Context:
Most of the differences in the revised budget deficit numbers were due to a temporary change of accounting practices by the new government, i.e., recording expenses when military material was ordered rather than received. However, it was the retroactive application of ESA95 methodology (applied since 2000) by Eurostat, that finally raised the reference year (1999) budget deficit to 3.38% of GDP, thus exceeding the 3% limit. This led to claims that Greece (similar claims have been made about other European countries like Italy) had not actually met all five accession criteria, and the common perception that Greece entered the Eurozone through "falsified" deficit numbers.

Question:
What were the majority of the differences in the revised budget due to the temporary changing of?
