3  The fiscal regime

51. Profits arising from the extraction of oil and gas in the UKCS potentially fall within two fiscal regimes: petroleum revenue tax (PRT) and ring-fenced corporation tax (RFCT), which also incorporates supplementary charge (SC or SCT). PRT is a field-based tax and can produce an assessable profit or an allowable loss; the latter may be taken forward and set against later profits from the same field. It does not apply to fields given development consent on or after 16 March 1993. Corporation tax on upstream oil and gas is levied at 30%. A supplementary charge of ten per cent on adjusted ring fence profits was introduced in 2002 and increased to 20% in 2006. Adjusted ring fence profits are the amount of profit or loss arising from any ring fenced activities, excluding any financing costs. Fields not paying PRT will thus be liable to a marginal tax rate of fifty per cent.

52. This fiscal regime has led to very significant tax receipts for the public purse. Oil & Gas UK's 2008 Economic Report estimated that, over the previous four decades, the industry had provided £248 billion in tax revenues to the UK Exchequer and that 2008's high prices would result in tax receipts of around £15 billion for the fiscal year (assuming an average price of $110 for 2008), with a further £5-6 billion in tax receipts added from UK supply chain activity, primarily from Corporation Tax and payroll contributions.[60] However, the regime is unpopular with those subject to it. Oil & Gas UK told us that "the current fiscal regime is no longer fit for purpose. It appears to be designed to maximise short-term revenues for the Treasury at the risk of long-term recovery of reserves and security of energy supply."[61]

53. Oil & Gas UK has argued - unsurprisingly perhaps - that the overall tax burden on the mature UKCS   must be reduced and that "difficulties in attracting and maintaining investment in the UKCS for projects of all kinds have been suddenly and materially increased." It goes on to argue:

    When the oil price was last in the $40-$45 per barrel range, new developments were subject to a tax rate of 40%, but are today liable to 50%. Certain mature fields are subject to a marginal tax rate of 75%. The mismatch of tax rate and current business environment is detracting from the value of investment and is contributing to the dampening of that investment.   Government help is urgently needed for both established companies and the new smaller businesses that have been explicitly encouraged into the basin by Government policy. Material improvements in the current tax regime are now required to stimulate additional capital investment both through the current downturn and in the longer term.[62]

54. BP told the Committee that while in recent years the UKCS fiscal regime had not been "draconian or uncompetitive in global terms", the difficulty was "that it has not adapted sufficiently to the needs of a mature basin. One of the characteristics of a mature basin is that geographically and commercially, every aspect of the operation becomes much more difficult. Many of these aspects are beyond human influence; but this means that those which are capable of adjustment (i.e. regulatory and fiscal) become even more significant."[63] Therefore, BP argues that one key factor for maximising the potential of remaining reserves is:

    A competitive and less complex fiscal regime which recognises the growing challenges facing the North Sea industry and the need to reduce the tax burden on a sustainable basis as the basin continues to mature.[64]

55. The complexity of the fiscal regime was also highlighted by the Independents' Association, which also argued for the regime to be predictable in order to inspire confidence in potential operators:

    The UK fiscal regime is extremely complex and a result of 40 years of constant tinkering. It was developed when fields containing hundreds if not billions of barrels were being found. It is now recognised as a fiscal environment with significant risk of (adverse) change. For investors to invest they will always make assumptions about the stability of the tax system prior to investing. The UK does not fare well in this regard, particularly as it requires very significant upfront investments over a number of years prior to cash flow. One actual example would be an exploration investment made on the basis of a 30% tax regime in 2001, which then changed to a 40% regime whilst the discovery was being evaluated for development, and finally became 50% when the bulk of the development capital (totalling $3bn) had already been committed. Is this an environment that encourages sustainable and long term investment? The industry understands that the UK needs a fair return on the development of its resources, however we need to consider a tax regime that is above all predictable, [and which] encourages new investment in maximising the development of remaining hydrocarbons from the basin…[65]

The concept of a Value Allowance and the introduction of the Field Allowance

56. The Government has recognised that the fiscal regime needed to adapt and, following a consultation launched at the 2008 pre-budget report, introduced measures in the 2009 Budget designed to support investment in the UKCS. DECC told us that

    Central to this package is the introduction of a new "Field Allowance" (described in the consultation document as a "value allowance"). This will give incentives to encourage investment in small or technically challenging fields, which could assist in unlocking around 2 billion barrels of the UK's remaining oil and gas reserves. It will be targeted at new small fields, with an allowance set at £75 million, and at challenging new High Pressure High Temperature or Heavy Oil fields, with the allowance set at £800 million. The introduction of the Field Allowance marks a significant change to the approach of the North Sea Fiscal Regime. The Government believes it has the potential to make an important contribution to the competitiveness and attractiveness of investments in the UKCS.[66]

In the Budget statement the Chancellor told the House that he was "bringing forward incentives to encourage smaller fields to be brought into production, which could lead to an extra 2 billion barrels of oil and gas that would otherwise remain under the North sea."[67]

57. The Government's Budget Note 10 further explains the operation of the Field Allowance:

    A new 'Field Allowance' is to be introduced which will provide certain categories of new field with a fixed allowance which can, over time be offset against the supplementary charge payable by the companies involved in the field. Once that allowance is exhausted the field will, in effect, pay the full North Sea rate of tax. The speed of exhaustion will depend on the profitability of the company - i.e. if oil prices rise then, all other things remaining equal, the allowance will be exhausted more quickly. The field allowance applies to small fields, ultra heavy oil fields and ultra high temperature/high pressure fields:

    ? the field allowance for small fields is £75 million for fields with oil reserves (or gas equivalent) of 2.75 million tonnes or less, reducing on a straight line basis to nil for fields over 3.5 million tonnes. In any one year the maximum field allowance (for a field with total allowance of £75 million) is £15 million;

    ? the field allowance for ultra heavy oil fields is £800 million for fields with an American Petroleum Institute gravity below 18 degrees and a viscosity of more than 50 centipoise at reservoir temperature and pressure. In any one year the maximum field allowance is £160 million; and

    ? the field allowance for ultra high temperature/pressure fields is £800 million for fields with a temperature of more than 176.67 degrees Celsius and pressure of more than 1034 bar in the reservoir formation. In any one year the maximum field allowance is £160 million. [68]

58. Before the detailed measures were announced in Budget 2009, the concept of a field allowance (known as a value allowance in its earlier iteration in the 2008 consultation document) was given a qualified welcome by some witnesses to our inquiry. The BG Group told us that the allowance "could lead to security of supply benefits with oil and gas volumes that would not otherwise have been produced becoming commercially viable… [and] that high pressure, high temperature (HPHT) fields that are expensive to drill and technically challenging and small field discoveries close to existing infrastructure could benefit in particular from a Value Allowance".[69] Oil & Gas UK's evidence said that it was "a welcome step in the right direction" but argued that "additional and bolder" steps were required.[70]

59. However, other witnesses were less convinced of the benefits of such an allowance. BP told us the "Value Allowance by itself cannot make the material difference required in the current economic and oil price environment. It will also further complicate the already excessively complex fiscal regime, counter to BP and industry advocacy of simplification and the desired move towards a level playing field for investment decisions."[71] Shell said that, while it saw "some merit" in the value allowance proposals, it thought that "Government is missing major opportunities in not targeting both new developments AND incremental investment in existing fields. Bringing on incremental production is a huge challenge in the current environment and we believe that Capital Uplift[72] is a more effective measure to bring incremental projects on-line. We believe the VA proposal benefits only a small portion of the UKCS portfolio, in addition to being complicated and prohibitively expensive for Government to make a real difference. Moreover, it does not address brownfield expenditure, where the largest opportunity sits".[73]

60. Other witnesses agreed that it was important to support further incremental production in fields already in production, and that the value allowance as proposed by the Government would not achieve this. Centrica told us:

    There is more to be gained from maximising recovery from existing fields than there is from developing new marginal sources of oil and gas. HM Treasury's proposals for a value allowance appear to incentivise the development of new marginal fields over the exploitation of existing opportunities, ignoring the advantages of existing infrastructure. Centrica supports a broader capital uplift allowance, which would incentivise both new and existing fields on a comparable basis.[74]

Oil & Gas UK - while, as we noted above, calling the value allowance a step in the right direction - said that "to have any effect, it must be material in scale for both new and incremental investment."[75] BP also emphasised the important of encouraging incremental investment: "incentives must be made available to encourage incremental investment options in existing fields through the provision of capital uplift".[76]

61. In its 2008 consultation document, the Government made it clear it did not support this proposal, for the following reasons:

    —an across the board uplift would represent a blunt instrument as it would apply to all capital expenditure, including already sanctioned expenditure. It would not therefore effectively target support on those fields facing the greatest challenges within the UKCS.

    —it would involve significant deadweight cost. Whilst it was argued in the course of the discussions that this deadweight cost could be offset by the resulting increased production, more detailed analysis has suggested that this is unlikely to be the case. This proposal would therefore also undermine the principle of maintaining a fair return to the UK taxpayer.

    —implementation of such an incentive would be neither simple to design or operate. Giving relief for 125 per cent of capital costs would require either a fundamental rewriting of large parts of the capital allowance rules (to take account of relieving more than 100 per cent of cost) or the introduction of a whole new relieving mechanism for the additional 25 per cent uplift. Either would require large amounts of additional legislation, and additional ongoing compliance obligations for both HMRC and companies. [77]

62. Another option put to us as a favourable alternative to a value allowance was a reduction in the supplementary charge (SC or SCT). Total E&P told us:

    There is a strong argument for the reduction of SCT rather than a complex Value Allowance determination which is proposed by HM Treasury. A simple reduction in SCT would be unambiguous, simple and give a direct signal to industry that Government is committed to helping sustain the UKCS. This is for us the major point. Taking into account the lack of visibility of future prices, decisions to proceed with new projects are difficult to take and such a signal from government would have a real impact.[78]

BP agreed, telling us "a more appropriate fiscal reform would be a straight forward and significant reduction of the rate of SCT, which would achieve more effectively and simply the objectives held out in the Value Allowance proposal."[79]

63. The Government considered the case for a reduction in the supplementary charge in its 2008 consultation document, but did not favour this option:

    The Government does not believe that an across the board reduction in the rate of SC would be desirable. This would act to give the greatest incentive to those projects with the greatest profitability, which by definition are those that least require support, and therefore would result in significant deadweight costs. Moreover, whilst the Government recognises that some new fields may require additional support…the Government believes that overall the fiscal regime is appropriately balanced and set at the correct level to ensure a fair return to both producers and consumers.[80]

64. Having set out its stall against a capital uplift and a reduction in the rate of supplementary charge, the Government announced in Budget 2009 that a field allowance was to be introduced. Following this announcement we received further evidence from some in the oil and gas industry setting out their reactions. BP said that "the provisions in the Budget will fail to have any significant effect upon BP's planned activity levels in the UKCS. We do not oppose the Value Allowance, now defined as Field Allowance, as formulated in the Budget; but it does not go nearly far enough to assist our own activities or indeed, we would argue, the wider interest of the Industry and the nation".[81] They criticised the field allowance because, they argued:

  • It does not provide any assistance for fields currently in production or for the area west of Shetland. Thus, they state that "the sharp fall in UKCS platform drilling activity already witnessed during the first quarter of 2009 will soon translate into accelerated production declines in those fields where infill drilling has been reduced or ceased".[82]
  • There are excessively high qualifying criteria for the allowance, especially regarding high pressure/high temperature (HPHT).

65. The latter point, regarding HPHT, led BP to a highly critical conclusion concerning the field allowance provisions:

    we expect that this measure will have a negligible impact on UKCS investment. Indeed, it seems that only one HPHT undeveloped discovery in the North Sea satisfies the stipulated temperature and pressure criteria, both of which must be met in order to qualify. It certainly won't affect BP's behaviour as none of our five HPHT discoveries meets this onerous criteria. The reality appears at odds with the Chancellor's statement that the Field Allowance would encourage the development of up to a further 2 billion barrels of oil equivalent. If the Government had accepted Industry's proposals in respect of the HPHT qualifying criteria, this measure could have made a significant medium term difference to industry investment. As it stands, this appears impossible.[83]

66. Oil & Gas UK welcomed the allowance as a recognition by government "that it needs to reduce the tax burden to stimulate investment in the mature UKCS".[84] They also said that the allowance was a "modest step forward and will offer some limited incentives for the development of marginal fields". However, their evidence stated that:

    our members tell us that it will do very little to improve the UK's competitiveness or attractiveness for investment when competing for capital on a global scale. Given the limited scope and extent of the allowance, it is only likely to accelerate the development of one or two marginal small fields over the next couple of years. We certainly do not see it reversing the decline in capital investment.[85]

In addition to the specific points below concerning HPHT and incentives for new fields, the organisation was concerned that the allowance:

  • Does not apply to existing fields and so will "do nothing to address the collapse in investment in brownfields, nor will it reactivate drilling campaigns which have currently halted";
  • Will have a negligible effect on exploration activity; and
  • Will not encourage production west of Shetland or tight gas development.[86]

The Oil and Gas Independents' Association have also told us that the Government should look at extending the allowance to assets west of Shetland and non-conventional gas.[87]

67. Oil & Gas UK agreed with BP that the qualifying threshold for HPHT - at 15,000psi and 350F - is too high and noted that the original thresholds proposed were pressures of 10,000psi and 300F. They were also concerned that the threshold for ultra heavy oil fields is prohibitive. They state that "in both heavy oil and even more so for HPHT, these are tighter technical limits than were proposed by Oil & Gas UK and many of our members have expressed strong reservations about the allowance's efficacy in light of their opinion that it is only likely to have very limited impact."[88] The Oil and Gas Independents' Association have also called for the HPHT criteria to be less stringent.[89]

68. Oil & Gas UK are also concerned that the allowance will have limited success in encouraging new fields. They estimate that the allowance will typically increase the economic value of new small field developments by around £8 million on a discounted post-tax basis, which they say should be compared to the scale of investment - typically between £100 - 200 million which the allowance is trying to encourage. They note Professor Kemp's estimate that the allowance for small fields could add around 400 million boe over the life of the UKCS.[90] To put that figure in context, it equates to approximately 2% of the 20 billion boe which is DECC's best estimate of remaining recoverable hydrocarbon resources from the UKCS. It is a fifth of the additional production which the Chancellor said his budget proposals could stimulate.

69. The general consensus amongst our witnesses - that the field allowance's beneficial effects will be limited - was shared by Shell UK. While, like others, they were pleased that the Government had recognised the difficulties faced by the industry, they were concerned that "the proposed scope, criteria and levels for the incentives set out in the 2009 Budget are not enough to reverse the projected decline in capital investment in the UK continental shelf (UKCS) and will not have adequate impact on the UK's competitiveness and attractiveness to win global investment. We believe the measures will result in only a relatively limited increase in activity in the UKCS."[91] Analysing the potential impact of the allowance on their entire UKCS portfolio, Shell found that:

  • Only one development prospect would potentially qualify for the Field Allowance for small fields, but that the allowance is too small for it to be a deciding factor in capital allocation
  • Only one field might qualify for the ultra Heavy Oil fields allowance, and again the impact on the project's economics would not move the project out of the marginal category
  • The ultra High Pressure High Temperature allowance will have a significant effect on only one block.

For these reasons, the company concluded that the allowance "will only potentially incentivise a very small portion of our portfolio and we believe it is unlikely that these measures will generate the additional two billion barrels of oil predicted by the Chancellor".[92]

70. Shell UK, like other witnesses, felt that the allowance's impact will be limited as it does not incentivise investment in brownfield sites. They made the case that "in the present economic climate bringing on incremental production on producing fields is hugely challenging. Efforts to extend field life and increase recovery of existing fields are more marginal than in past years due to lower oil price, smaller targets and high reservoir complexity" and therefore argued that it was a "critical priority" for government to align an incentive for brownfield developments alongside the Field Allowance as presently proposed.[93]

71. We welcome the introduction of the field allowance in so far as it acknowledges that the tax burden on companies operating in the UKCS needs to be altered in order to stimulate vital investment. However, we are very concerned that the allowance seems to be flawed in a number of fundamental ways. The main problem is that it does not incentivise incremental investment in existing sites. Furthermore, we are concerned that: it is likely to be ineffective in encouraging investment west of Shetland; the criteria for qualifying for the allowance are so stringent (especially with regard to HPHT) that its effect will be minimal; and its modest scale is such that it will not provide a significant incentive for investment even in new fields. We share the concerns of witnesses that the allowance will not stimulate the production of the 2 billion extra barrels of oil hoped for by the Chancellor.

72. The Government should review the operation of the allowance in its first year of operation and be prepared to extend its scope and widen the qualifying criteria in light of that review. In any event, we think there is a very strong case for widening the allowance so as to provide a meaningful incentive for investment west of Shetland and to encourage HPHT opportunities. Furthermore, much of the UKCS remaining reserves are in fields which are not new but which will not be further exploited unless the fiscal regime makes incremental investments more attractive. This is especially the case in PRT-paying fields where the overall tax rate is 75%.

73. We note the Government's reasons for pressing ahead with a value or field allowance, rather than options which appear to have the benefit of being less complex and of incentivising a wider range of production, such as an across-the board capital uplift or a reduction in (or the removal of) the supplementary charge. We recommend that in reviewing the operation of the field allowance and assessing its effectiveness in increasing investment the Government be prepared to reconsider the merits of these bolder moves. It should calculate and set out the predicted effects on production and tax revenues of a capital uplift or a reduction in supplementary charge alongside the effects on investment in the industry. We recognise that the nation should receive a return in the form of both economic production and tax revenues from the UKCS.

Other measures in the Budget

74. DECC told us that the budget provisions relating to the North Sea fiscal regime "also include measures to assist asset trades and give companies the certainty and stability they need to underpin investment. In brief, in addition to the new Field Allowance, the package of reforms announced at Budget comprises:

  • Changes to the chargeable gains regime within the North Sea ring-fence to remove chargeable gains entirely from licence swaps and making gains exempt where disposal proceeds from ring fence assets are reinvested within the UKCS.
  • Changes to the North Sea fiscal regime to remove potential barriers to projects that re-use North Sea infrastructure for non-ring-fenced purposes including gas storage, carbon capture and storage and wind energy.
  • Amending the petroleum revenue tax (PRT) regime to ensure that companies whose production licences have expired are still able to access PRT decommissioning relief where appropriate.
  • Changes to the PRT regime to reduce the administrative burden it imposes, simplify compliance and repeal obsolete legislation."[94]

75. Our witnesses generally welcomed such measures. Oil & Gas UK said that the change to the chargeable gains regime should "help encourage asset trading which has slowed down significantly in recent years."[95] Shell UK welcomed "the encouraging announcement with respect to North Sea asset transfers. All of the measures contained within the Budget to assist asset trades i.e. changes to the chargeable gains regime, amending PRT etc … provide very helpful certainty and stability. It was also encouraging that the Change of Use issues identified in the November 2008 PBR were included in the Budget papers with the additional good news that HMRC are now willing to accept that the cost of Cushion Gas in Change of Use projects will, as requested by Industry, be treated as plant for the purposes of Plant and Machinery Capital Allowances. Finally we were also encouraged that the PRT decommissioning concern from Industry (post licence expiry decommissioning cost) was also addressed in the Budget."[96] BP too welcomed these technical measures as "necessary improvements for which we are grateful. Unfortunately, however, they are not material in terms of encouraging additional investment."[97]

76. The Government was right to listen to the concerns of the industry regarding specific issues relating to the chargeable gains regime, the re-use of North Sea infrastructure for non-ring-fenced purposes and the operation of the Petroleum Revenue Tax. The changes announced in the Budget regarding these areas are modest but welcome.

77. A specific change to the fiscal regime sought by the industry was for smaller companies to be able to benefit from tax allowances at an earlier stage. Oil & Gas UK said it would welcome "accelerating the payment of accrued, but so far unrelieved, tax allowances to smaller companies. [This]…would release much needed capital to small companies for investment in the basin at minimal cost to the Government. The Government has pursued a laudable policy to attract these smaller companies into the basin. It should throw this inexpensive lifeline to them now and not simply abandon them".[98] Following the Budget, the organisation was disappointed that "the government… failed to act on our proposals to provide cash relief of unexpensed "Ring Fence Expenditure" which would have helped small companies and given a much needed boost to exploration".[99]

78. DECC's memorandum noted the operation of the "Ring Fence Expenditure Supplement (RFES) [which] assists companies that do not yet have any taxable income for corporation tax or the supplementary charge against which to set their exploration, appraisal and development costs and capital allowances. The RFES increases the value of unused expenditure carried forward from one period to the next by a compound 6 per cent a year for a maximum of six years. It applies to all unrelieved expenditure from 1 January 2006. This is intended to help support new entrants into the basin".[100]

79. We note the case presented to us by industry representatives for accelerating the payment of accrued but unrelieved tax allowances to smaller companies and their argument that the lack of equity and debt financing makes this particularly desirable. We urge the Government to estimate the costs and potential benefits of this proposal as a means of tackling the impact of the credit crisis on investment in the UKCS.

80. The Budget's provisions regarding the field allowance and the technical matters noted above are welcome as far as they go. Industry representatives were positive about the dialogue that has gone on with Government.[101] However the evidence we received from most industry representatives argued that the measures announced in the Budget do not go far enough:

    The government failed in the recent Budget statement to take the necessary strategic action that will encourage the maximum recovery of its indigenous oil and gas reserves and ensure that these precious resources can play a full role in helping to meet the UK's future energy needs. Time is running out and corrective action now needs to be taken. (Oil & Gas UK)[102]

    There is still a material risk that UKCS investment will fall sharply over the next couple of years. While this is not related exclusively to the Fiscal Regime, it is clear from BP's perspective that the Budget's fiscal package will make no difference to our own investment plans. We expect the same applies to the industry as a whole. (BP)[103]

    Overall Shell U.K. Limited welcomes the measures in the April 2009 Budget as a step in the right direction. However we believe it is not enough to reverse the projected decline in capital investment in the UKCS, will have little impact on the UK's competitiveness and attractiveness to attract global investment and ultimately result in a relatively limited increase in activity in the UKCS…. We are firmly of the belief that the proposed measures are not enough. The need to incentivise additional development has become even more pressing since discussions started, with the additional dimensions of an economic recession and associated challenges re access to capital and the collapse in the oil and gas prices. The effects of this are being seen by the rapid decline in the capital and exploration expenditure within the sector. We do not believe that the changes contained within the 2009 Budget are adequate to attract investment and stimulate activity at a sufficient level. (Shell UK) [104]

81. In their evidence to us the Government said that while "there is no stated "next step" for the discussions…. that should certainly not be taken as a sign that the Government considers that the process of engagement is at an end. The Government will continue to engage with stakeholders wherever necessary to ensure that the North Sea fiscal regime continues to help deliver the best possible future for the UKCS. In particular, officials from both DECC and HMT/HMRC have been asked to look further into the question of post tax decommissioning security and to discuss this complex area with Industry in the coming months."[105]

82. We would be surprised if industry representatives did not call for a more congenial tax regime. However, it does seem to us that concern that the Government's fiscal reforms do not go far enough are genuine and legitimate. The quadruple whammy faced by the industry - of high costs, low prices, lack of affordable credit and a global recession - make this a difficult time. We are not convinced that the field allowance and other measures announced in Budget 2009 - albeit welcome - are sufficient to create the competitive environment needed by the industry nor that they will provide a strong enough incentive to exploit fully remaining resources. We note and welcome the Government's commitment to further engagement and hope that, should the measures so far announced prove to be inadequate, more wide-ranging and generous reforms of the fiscal regime will be forthcoming. A key part of the UK's energy security strategy and the prospects of the 350,000 people who work in or with the UK oil and gas industry depend on it.
