Funding based on solidarity

OIMAP is funded essentially by the annual contributions of its 67 Member States. Each State pays an amount set by a scale that takes account of its national wealth and the size of its art market. This mechanism guarantees the Organization's independence and the predictability of its budget.
This section presents the scale, the payment arrangements and the financial report published each year.
Candidate States will find the rules applying to their first contribution on the accession contributions page.

The principle of contributions
Contributions are due from all Member States, without exception. They fund the running of the Secretariat, the offices in Paris, Geneva, New York, Singapore and Nairobi, the Desk services, training programmes and technical cooperation.
The amount is set by the General Assembly, which adopts the budget and the scale. Each State has one vote, whatever the level of its contribution: financial participation confers no additional right.
A scale in five bands
The scale combines two criteria: the State's gross domestic product and the weight of its art market. It divides States into five bands, from the most modest to the highest. The minimum contribution is €12,000 per year and the maximum €2.4 million (indicative amounts).
This progressive structure allows smaller States to participate fully while ensuring that the largest markets bear a proportionate share.
The annual calendar
The budget cycle follows the calendar year. Contribution notices are sent in January. Payment is expected before 31 March, by transfer or direct debit. A reminder is sent in April to States that have not paid.
The accounts for the financial year are closed the following spring, submitted to an external audit and then presented to the General Assembly. The financial report is then published.
Transparency and oversight
Each year the Organization publishes a detailed financial report: revenue, expenditure by programme, status of arrears. The accounts are audited by an independent firm, appointed by the General Assembly for a limited term to guarantee its impartiality.
States may question the Member States Relations Directorate about the use of their contribution, and focal points receive an individual statement of their position.

Payment difficulties
A State facing a temporary difficulty may request an instalment plan. The request is examined sympathetically by the Directorate, which proposes a settlement plan over several months. The Organization always prefers dialogue to sanction.
However, a delay of more than twenty-four months results in the loss of voting rights, as explained in the rules on suspension.
