Natural Oil Companies and Value Creation : Volume 2. Case Studies
(World Bank, Washington, DC, 2011-03)Approximately two billion dollars a day of petroleum are traded worldwide, which makes petroleum the largest single item in the balance of payments and exchanges between nations. Petroleum represents the larger share in total energy use for most net exporters and net importers. While petroleum taxes are a major source of income for more than 90 countries in the world, poor countries net importers are more vulnerable to price increases than most industrialized economies. This paper has five chapters. Chapter one describes the key features of upstream, midstream, and downstream petroleum operations and how these may impact value creation and policy options. Chapter two draws on ample literature and discusses how changes in the geopolitical and global economic environment and in the host governments' political and economic priorities have affected the rationale for and behavior of National Oil Companies' (NOCs). Rather than providing an in-depth analysis of the philosophical reasons for creating aNOC, this chapter seeks to highlight the special nature of NOCs and how it may affect their existence, objectives, regulation, and behavior. Chapter three proposes a value creation index to measure the contribution of NOCs to social value creation. A conceptual model is also proposed to identify the factors that affect value creation. Chapter four presents the result of an exploratory statistical analysis aimed to determine the relative importance of the drivers of value creation. In addition, the experience of a selected sample of NOCs is analyzed in detail, and lessons of general applicability are derived. Finally, Chapter five summarizes the conclusions. -

Sovereign Wealth Funds and Long-Term Development Finance : Risks and Opportunities
(World Bank, Washington, DC, 2014-02)Sovereign wealth funds represent a large and growing pool of savings. An increasing number of these funds are owned by natural resource exporting countries and have a variety of objectives, including intergenerational equity and macroeconomic stabilization. Traditionally, these funds have invested in external assets, especially securities traded in major markets. But the persistent infrastructure financing gap in developing countries has motivated some governments to encourage their sovereign wealth funds to invest domestically. This paper proposes some basic elements of a conceptual framework to create a system of checks and balances to help ensure that the sovereign wealth funds do not undermine macroeconomic management or become a vehicle for politically driven "investments." First, the risks and opportunities of domestic investment by sovereign wealth funds are analyzed. Central issues are the relationship of sovereign wealth fund financing to the budget process and to the procurement systems of sector ministries, as well as the establishment of appropriate benchmarks and safeguards to ensure the integrity of investment decisions. The paper argues that a well-governed sovereign wealth fund, with a sound mandate and professional management and staffing, can possibly improve the quality of the public investment program. But its mandate should not duplicate that of other government institutions with investment mandates, such as the budget, the national development bank, the investment authority, and state-owned enterprises. Establishing rules on the type of investment (for example, commercial and/or quasi-commercial) and its modalities (for example, no controlling stakes, leveraging private investment) is one way to ensure separation between the activities of the sovereign wealth fund and those of other institutions. The critical issue remains that of limiting the sovereign wealth fund's investment scope to that appropriate for a wealth fund. If investments that generate quasi-market returns are permitted, the size of the home bias should be clearly stipulated and these investments should be reported separately. -

Experiences with Oil Funds : Institutional and Financial Aspects
(World Bank, Washington, DC, 2006-06)This study brings together detailed information on the creation, operation, and financial performance of 12 oil funds and 3 other resource funds. The report looks at various funds in Alaska, Alberta, Azerbaijan, Norway, Chad, Sao Tome Principe, Timor, Chile, Nauru, Papua New Guinea, Kazakhstan, Kuwait, Oman, Venezuela, and Russia. The purpose of the study is to provide comparative information on the backgrounds of the creation of these funds, the legislation used to do so, the details of the organization and management of the funds, and of their financial performance. The report opens with a brief review of the reasons for establishing an oil fund and the principal issues involved. The report then provides detailed coverage of four oil funds where there is substantial public information about the operation and performance of the funds. The final chapter provides some comparative material on the different funds and explores the construction of a set of indicators for good practice in the design of the funds. The appendixes contain the legislation which created the governing funds. -

Crude Oil Prices : Predicting Price Differentials Based on Quality
(World Bank, Washington, DC, 2004-10)Many developing countries are becoming oil exporters, producing crude oils that often differ markedly in quality from those principally traded. Governments must predict the prices of such crudes, to forecast revenue and evaluate the fairness of the price they receive from companies selling on their behalf. Oil companies, and industry consultants, have models for analyzing price differentials with well-known "marker" crudes, but these models have not been widely known, or adapted to account for increasingly important quality characteristics, such as acidity. This note explains a methodology for price analysis, and a new extension for incorporating acidity, which can have a big effect on the price differential. -

Managing Resource Rents : The Special Challenges in Postconflict Countries
(World Bank, Washington, DC, 2006-02)Resource flows from extractive industries can be a lifeline for postconflict countries, helping to fund critical reconstruction needs. But these resources present issues not found elsewhere in the economy and need to be well managed. Sector governance principles that apply to oil-producing countries in general are even more important in postconflict countries. This note discusses these principles and shows how they apply in two cases, Timor-Leste and Sudan. -

Fiscal Systems for Hydrocarbons : Design Issues
(Washington, DC: World Bank, 2007)Although host governments and the investors may share one common objective-the desire for the project to generate high levels of revenue-their other goals are not entirely aligned. Host governments aim to maximize the rent for their country over time, while achieving other development and socioeconomic objectives. Investors' aim is to ensure that the return on investment is consistent with the risk associated with the project, and with their corporations' strategic objectives. To reconcile these often conflicting objectives, more and more countries rely on transparent institutional arrangements and flexible, neutral fiscal regimes. This paper examines the key elements of the legal and fiscal frameworks utilized in the petroleum sector and aims to outline desirable features that should be considered in the design of fiscal policy with the objective of optimizing the host government's benefits, taking into account the effect that this would have on the private sector's investment. Chapters 2 and 3 provide background material on, respectively, the stages of an oil and gas project and the type of legal arrangements normally used in the petroleum sector. The relative advantages and disadvantages of the tax and non-tax instruments used in petroleum fiscal regimes are discussed in Chapter 4. Chapter 5 outlines the features of successful fiscal regimes, while system measures and economic indicators are described in Chapter 6. Finally, in Chapter 7, a sensitivity analysis is used to illustrate some typical fiscal systems' design issues. -
