  1. Results of the survey on sub-soil assets in OECD countries Working Party on National Accounts 14-16 October 2008 Young-Hwan Kim, OECD

  2. Introduction • After land, sub-soil assets are the second most important non-produced assets • Like land, the lack of estimates of the stock of sub-soil assets is a major impediment for productivity studies and measuring national wealth • The OECD Secretariat conducted the survey on sub-soil assets in the (northern) summer of 2008

  3. Questionnaires • Type of sub-soil assets estimated • Institutional breakdown • Methods used to derive estimates • Reasons for not deriving estimates • Volume estimates

  4. Results of the survey • 15 countries responded, of which 7 countries reported that they derive estimates of the stock of sub-soil assets • Canada, Czech Republic, Korea, Mexico, the Netherlands, Norway, and the United Kingdom

  5. Types of sub-soil assets estimated

  6. Institutional breakdown • Canada, Norway and the UK : Total value only • Korea, Mexico : General government (S.13)   • The Netherlands : Non-financial institutions, General government

  7. Methods used • Three methods are used to derive estimates of the stock of sub-soil assets • Net present value method • Net price method • User cost method

  8. Net present value method • In the case of assets for which the returns are spread over a lengthy period, the 1993 SNA recommends the use of the net present value approach • Canada, Korea, the Netherlands, Norway and the United Kingdom

  9. Net present value method • The net present value of sub-soil asset resources are usually determined by the present value of the expected net returns resulting from the commercial exploitation of those assets, although such valuations are subject to uncertainty and revision (1993 SNA 13.59-13.60)

  10. Net present value method • 4 % discount rate is currently used in Canada and UK • 8% rate of return on capital is used in the UK, based on Eurostat recommendations

  11. Net price method • Canada, Mexico • Resource rent per unit of the asset* extracted in the current period multiplied by the quantity of the proven reserves of the sub-soil asset that are exploitable under present economic conditions * price minus marginal cost of extraction, development and exploration including a normal rate of return on invested produced capital

  12. Net price method • Canada uses the net price method as well as net present value method • Two different estimates of the stock of sub-soil assets using the net price method: one with no return to capital and another with a 4.25% rate of return to capital

  13. User cost method • Known as the El Serafy method • El Serafy argued that the resource rent should be divided into two elements: • one is a true income (X) that can be consumed, and one is a depletion cost or user cost (RR-X),which is invested to create a perpetual stream of income that would provide the same level of true income

  14. User cost method • Three assumptions: • The current level of resource rent: Constant • The rate of extraction: Constant • The discount rate: Constant • Simplified version of the net present value method

  15. Volume estimates • Statistics concerning volume estimates are mainly available from the official government data sources • No volume estimates : Korea, Czech Republic

  16. Summary • 7 countries estimate the stock of sub-soil assets: Canada, Czech Republic, Korea, Mexico, Netherlands, Norway, and United Kingdom • The estimates are published as part of the national balance sheet (Canada), national wealth survey (Korea), a set of indicators of sustainable development (Norway), and environmental accounts (Mexico, UK, the Netherlands).

  17. Summary • Those countries mainly derive estimates of the stock of oil and gas • Canada and Korea also derive estimates of the stock of metallic mineral reserves and non-metallic mineral reserves

  18. Summary • Five countries use the net present value method: Canada, Korea, the Netherlands, Norway, and the United Kingdom • Mexico uses the net price method because of its advantage of simplicity • Canada derives three different estimates (Net present value, Net priceⅠandⅡ) because it believes that there is no consensus on what the best method is
