3 1. Natural Gas in India Gas forms 11% of India s primary energy consumption Relatively young but growing sector India s gas reserves 0.7% of world reserves Range of estimates Mostly offshore Consumption 60 Bcma (20-30% LNG) 70% used in power generation, fertiliser industry, household use, transportation Policy on gas Substitute for coal, naphtha, fuel oil Security of supply / mitigating energy shortages Environment

5 Pricing Prices for domestically produced gas are controlled To keep prices to consuming sectors low Prices are set according to the fiscal regime governing a producing field The fiscal regime has evolved over time; thus multiple pricing mechanisms India s 1999 liberalised upstream fiscal regime Prices based on an S curve formula with a cap and ceiling SP = $2.5 + (CP 25) C Five year reviews Formula rendered redundant by high oil price Ceiling of $60/bbl breached very early on Review of pricing currently underway; proposals to link it to Henry Hub, NBP and Japan LNG

7 Fiscal Regime for Gas Liberalised regime launched in 1999 New Exploration Licensing Policy Based on a Production Sharing Contract (PSC) Hybrid system (royalty + taxes on rent ) Main features 1. Royalty 10%, 5% for first 7 years 2. Cost recovery Opex, capex & royalty up to 100% pa 3. Profit Sharing Based on a R-factor, or the ratio of cumulative income to cumulative capital expenditure. Two tranches, 1.5 and 3.5. Shares in-between worked out using an extrapolation formula Z = a + [(b-a)*(x-1.5)/2] 4. Corporate Income Tax 30-40% 5. Minimum Alternate Tax 18.5% of book profits if IT payable is < 18.5% of book profits

9 Performance of India s Fiscal Regime Production Large initial increase (2009) followed by dramatic decline in production; currently a third of original targets Driven by private sector NOC production has remained stagnant No significant new discoveries since 2004 Investments Down from $4.7Bn in 2007 to $1.6 Bn in 2013 Arbitration & delays Companies accused of gold plating in the R Factor Alleged loss of revenues to exchequer Proposed Policy Solution Replace the PSC regime with a simple Revenue Sharing Contract (RSC) Regime Eliminate royalty, cost recovery and profit sharing (R Factor) Companies simply share a percentage of their revenues from day 1 of production Production slabs pre-specified by the government. Percentage revenue shares biddable by companies at the time of the auction rounds

11 2. Conceptual Literature on Resource Taxation What to Tax - The Base Net income / rent / liberal regimes Pure rent = surplus or financial return not required to motivate economic behaviour Supply price of investment = costs of capital and operation plus risk premium. Lower supply price, higher rent. Risk premium affected by policy Zero marginal fiscal take Requires information on production volumes, costs, prices, investments Gross income / proprietorial regimes Positive marginal rent, reservation ground rent, and excess profits Information on prices and volumes only Mommer (1999), Baunsgaard (2001), Hotelling (1931) How to Tax - The Instruments Net Income /rent Resource Rent Taxes (R Factor, Rateof-Return), Progressive Profits Taxes, Corporate Income Tax, VAT Gross Income Royalties, Bonuses, Fixed Fees, Minimum Work Programs Other Government equal partner Government/NOC equity participation, Brown Tax ( Most systems use a hybrid or combinations of both elements
12 Equivalencies in Fiscal System Design Production Sharing Royalties Corporate Income Tax Royalty rate = Tax rate = cost oil cap government profit share Resource Rent Tax Brown Tax Paid Equity Tax rate = equity share Carried Interest Tax rate = equity share Target real rate of return = interest rate Concessional Equity Source: Baunsgaard (2001) Tax rate = share of initial concessional investment Tax rate = equity share Target rate of return = interest rate
13 Desirable Features & Tradeoffs Desirable features of a fiscal system (Nakhle, 2008) Efficiency Neutrality Equity Sharing of fiscal risk Simplicity Stability of fiscal terms and of revenues Trade-offs between features Neutrality trades off with efficiency and with revenue generation Neutrality trades off with simplicity Equity trades off with simplicity and efficiency Stability trades off with fiscal risk sharing Selection of instruments is contingent upon the government s objectives in fiscal system design
14 Analogies with Price Cap versus RoR Regulation PSC regime analogous to rate-of-return system; RSC regime to price cap system PSC (RoR) necessitates information on volumes, costs, prices and investment RSC (Price Cap) necessitates information only on volumes and prices Under a price cap type system, the government will most likely need to accept a lower overall expected level of taxation and lower take but stable (yet lower) revenues Conversely, investors face greater risks in sinking investments into difficult (offshore) areas In utilities and resource taxation price cap systems almost always revert towards rate-of-return (Tapia, 2012; Helm, 2010; Liston, 1993) The setting of appropriate caps ultimately necessitates information on cost functions Governments may therefore be compelled to intervene ex post There is a case for incorporating RoR elements into fiscal design ex ante
15 3. Empirical Literature Static Models: Discounted cash flow models using data on production, costs & prices under a high, medium and low case scenario. Fiscal terms used to compute economic measures. One or more of these are held constant to observe the effect of changes in the others. Results anchored to initial conditions employed. Restrictions on graphical representation of multidimensional data. Key Studies: Goldworthy and Zakharova (2010) Johnston (2003) Dongkun and Yan (2010) Daniel and McPherson (2010) Nakhle (2008) Tordo (2007) Al-Attair and Alomair (2005) Dharmadji and Parlindungan (2002) Iledare (2001) System Measures: AETR, IRR, sensitivity analysis AGR/ERR, savings index, take stat Government take, front loading index METR, AETR, NPV NPV, IRR, take NPV, IRR, take E&P costs Contractor take, IRR, NPV Prices, production, NPV, take Meta Models: A cash flow model of the system constructed and parameters of the system are defined and bound through design intervals based on historical data or reasonable assumptions combined with the given parameters in the fiscal system. Parameters of the system sampled from the design space and evaluated in the cash flow model. The results of the model and system parameters are then analysed and a linear model is constructed from the generated data.

29 7. Observation & Conclusions Variables that have significant effects across all economic indicators: PSC Regime Price Share of profits to the government at the lower tranche of the R factor ( trigger tranche ) Coefficients larger than price Variables that have significant effects across all economic indicators: RSC Regime Share of revenues to the government at the first production slab ( trigger slab ) Corporate income tax Government discount rate Trigger tranche / trigger slab reflect rate-of-return characteristics
30 Observations & Conclusions (2) The results for trigger tranche/trigger slabs in the PSC/RSC system are indicative of rate-of-return influences on the fiscal system With a RSC, it could deter investment in difficult (offshore) areas as there is less traction in the system to offset investor risk The government s objective in fiscal design appears contrary in the RSC: it desires higher production and higher (and earlier) revenues, but there is not enough traction to offset the higher risks that come with it Alternatively, it could explicitly incorporate the rate-of-return element into fiscal system design This could be done through retaining the PSC, but adding an element of cost uplift, for instance It could also be done through designing a rate-of-return based tax combined with corporate income tax and/or royalties, instead of a RSC Areas for further work; RoR systems; testing functional relationships further
