Supporting governments to negotiate complex contracts for investment projects

Our services

Negotiation support

We support governments to negotiate complex contracts in the extractive industries, energy, and infrastructure sectors. Our advice facilitates commercially viable investment projects that maximise economic, social, and financial benefits for host governments and their citizens.

Financial modelling

We develop financial models of investment projects that are simple, transparent, and accessible, no matter how complex the project. All our models are built to the FAST Standard and we train our clients to use, update, and develop models.

Tax policy and audit

We help governments to design tax policies that are efficient, fair, and generate revenues to fund public services and investment. We also assist revenue authorities to audit taxpayers in the extractive industries with a focus on transfer pricing and mineral valuation.

Case studies and insight

Getting more durable deals in extractives: knowledge is a power best shared

Investors in extractives projects frequently ask for tax incentives that they claim are necessary for financial viability. But how are governments to judge these claims when investors don't share the underlying data?

Negotiating a royalty pricing agreement in Liberia

Countries often collect royalties on the sale of their natural resources, but how can they be sure the price is right when a mining company sells iron ore to its own steel mills?
