During these meetings, topics concerning the activities and administrative affairs of the International Association of Geodesy were treated. Decisions or conclusions were drawn as follows.


1. Finances.

The Financial Report of the IAG for the period 1st January 1995 to 31st of December 1998 was presented by the Secretary General during the IAG opening session. In terms of IAG by-law 54 an ad-hoc Audit Committee must be appointed by the Council to "examine all expenditures and ensure that they were in accordance with the proposals previously approved". The Audit Committee appointed by the Council on 19th July 1999 consisted of:

    J. Adam, Hungary
    B.G. Harsson, Norway
    R.T. Wonnacott, South Africa

The Audit Committee met four times.

The Audit Committee performed the following:

  1. Examined an arbitrary selection of receipts and bank statements of both the IAG Account and the IAG Fund for the period of 1st of January 1995 to 31st of December 1998. The final quadrennial report and the interim annual reports for both the Account and the Fund have been audited by the firm of authorised public accountants Hans Borge Nielsen.

  2. Checked the balances appearing in the annual and quadrennial report of the IAG.

  3. Examined expenditures to ensure conformity with the budget for 1995-1999 as approved in Boulder in July 1995.

  4. Made enquiries which were clarified by the Secretary General C. C. Tscherning.


The Audit Committee makes the following comments on the IAG Account:

  1. The accounts are well presented and expenditure is supported by receipts and records.

  2. Multi-currency transfers have been clearly documented.

  3. During the review period the reserves held by the IAG rose by US$70.100,10 to US$ 93.693,23. This can be attributed to large savings on administrative items such as travel and communication. In addition, an unforeseen income from the AGU for a per capita attendance at the Boulder General Assembly and the Rio de Janerio Scientific Assembly increased the reserves.

  4. In spite of the surplus of US$ 70.100,10 the Audit Committee found that total spending on Grants, Symposia, Assemblies and Publications was in accordance with the approved 1995-1999 budget.


The Audit Committee makes the following comments on the IAG Fund:

  1. The accounts are well presented and expenditures supported by receipts and records.

  2. At the end of the reporting period, the IAG Fund showed a debt of US$ 7.273,46 which has been covered by the IAG Account. The loss has been incurred largely through travel grants and support provided to young scientists for symposia and scientific meetings.


The Audit committee makes the following recommendations

  1. It is recommended that the itemised allocation of expenditure and receipts be reviewed to give a truer reflection of these expenditures and receipts. Unspecified items such as "miscellaneous" and "others" should be kept to a minimum amount.

  2. It is recommended that the IAG Fund be incorporated into the IAG Account primarily to facilitate the efficient handling of multi-currency transactions and the administration of the accounts.

  3. The Audit Committee recommends that the IAG Council accepts the Financial report for the period 1995-1999 as presented to the Council at Birmingham in July 1999.


The Audit committee had the following acknowledgement

On behalf of the IAG Council, the Audit Committee would like to acknowledge the considerable time, effort and support provided by the Department of Geophysics of the University of Copenhagen. In particular the work of the secretariat staff of the Department must be acknowledged.


2. Elections

The elections were prepared by the Nominating committee chaired by W. Torge, which presented its list of candidates at the first meeting of the council on July, 19. The election took lace in the council on Wedensday, 21th. They resulted in the following structure of the IAG.
