Qualitative Risk (2) Flashcards
what do banks understand by supply risk
Ensuring a reliable supply of raw materials, necessary fuels and other inputs is naturally a major element in the securing of steady and dependable cashflow for the servicing of debt by any project.
minerals projects
upstream oil & gas, mining of metal ores, quarrying) have a special type of supply risk. This is because they generally have a limited reserve of material to exploit. Such deposits are “wasting” assets and once they are exhausted, no cashflow will be generated1.
renewables projects
ome renewable-energy projects also exploit naturally-occurring reserves – of wind or solar energy for example – which will not be exhausted. How much wind or solar irradiation will be available over a given period, however, is a matter of estimation. Project lenders have had to develop suitable methods for the assessment and mitigation of these risks.
transactions which require steady supplies of a fuel (such as a gas-fired power station) or feedstock (crude-oil refinery)
In such cases the risk is that the project will not be able to secure sufficient volumes of what it needs to operate at a price which will allow the generation of steady-state debt-servicing cashflow. There is thus a volume and a price risk.
volume risk
Of the two risks, project lenders will probably be more concerned by the existence of a significant volume risk
price risk
Prices can of course be volatile, but project lenders tend to be much more comfortable to accept a risk which they can assess through cashflow modelling and which may be capable of being managed (e.g., through price hedging).
quality issue
Certain projects may not be able to tolerate inputs whose quality lies outside a fairly narrow band. Combined-cycle gas-fired power stations, for example, are normally designed to run on gaseous fuel within a given “envelope” of calorific value and gas content (methane, nitrogen, other hydrocarbons etc.).
Fuel outside this envelope may be unacceptable for use and needs to be rejected. At the very least its use may cause significant performance shortfalls. Many biomass-based renewable power projects are very sensitive to the water content of their fuel (woodchips, straw, chicken-litter) and higher-than-expected moisture content will affect power output and therefore cashflow. The quality range of feedstocks which an oil refinery is able to accept is a critical factor in determining its refining margin and therefore its cashflow.
What do banks understand by reserve risk?
The factor which connects all reserve/resource-based projects is that the values we use for reserves or resources are generally estimates rather than precisely calculated quantities.
The calculation of these values is based on limited information, some extrapolation and the making of certain (hopefully clearly stated) assumptions. It is almost impossible to take away all trace of subjectivity from the calculations. Lenders recognise this and handle reserve and resource estimates with caution
estimating oil and gas reserves
Oil and gas reserve estimates are based on a limited number of physical penetrations of the underground petroleum reservoir. A discovery well will perhaps have been supplemented by a number of “appraisal” wells designed (among other things) to build up a better idea of the reservoir, to establish its upper and lower limits and to collect fluid samples.
offshore wells balance
such wells are enormously expensive, and a balance must be struck between:
- drilling further to build up additional data and reduce risk; and
- moving forward to field development on the limited information already available.
Furthermore, although the wells already drilled will give information on issues like the permeability and porosity of the rocks encountered, the ratio of oil/gas-bearing rock to non-reservoir rock and the amount of water saturation in the reservoir, this information is truly accurate only for a limited space around the well-bore. It will be necessary to extrapolate from this data to the wider field, where conditions could be (in fact are very likely to be) somewhat different.
Extra dimension of risk in mining and reservoirs
mining reserves add an extra dimension of risk in that they may not be homogenous in composition across a single deposit. There is potential for major variations in quality (e.g. in terms of grams of ore per tonne of rock) from one part of the ore body to another. The completeness of the owner’s understanding of the ore body will often therefore depend to a significant extent on the closeness of the drill holes which have been drilled to appraise the deposit.
front-loaded cash generation profiles
Projects based on oil and gas deposits and mining reserves frequently also have a front- loaded cashflow generation profile
In the case of a single oil or gas field this is frequently because pressure in the reservoir declines over time, making extraction more and more difficult/expensive. Therefore, production is highest in the earliest part of the reservoir’s life. A “plateau” production level may be maintained for a period, but inevitably production will begin to fall off until the economic cut-off point – the point where production costs exceed production revenues.
Factors of oil and gas and mining projects
a. a limited overall store of value, because they are wasting assets;
b. a front-ended cashflow profile;
c. significant scope for a difference between projected and actual reserve recovery.
Power projects from renewables
Should not suffer from:
a. a limited overall store of value, because they are wasting assets;
b. a front-ended cashflow profile;
Potential for variation between actual and projected amounts of energy turned into electrical power
verage wind-speeds vary significantly from season to season and from year to year. They will even vary very significantly within a particular wind-farm site, especially where the individual wind-turbines are at different heights. Close observations over an extended period of time (a number of years rather than one full operating season) will allow a skilled analyst to build a detailed model of a particular site’s wind resource. This model can then be tested against actual experience with real turbines once they are in place and generating. If the actual experience matches closely with predicted performance, the accuracy of the model will be progressively confirmed. Otherwise, the model will need to be revisited. This is of course very useful – but by this stage the project lender has already lent!
Mitigating and allocating supply volume risk
In some projects there is little or no volume risk to be considered on the supply side. Lenders to a newbuild gas-fired power station in the UK or the USA, for example, can have a high degree of confidence that it will be able to source its supplies of gas from a deep and well-supplied spot gas market, subject of course to being able to pay the prevailing price.
The situation for lenders to a newbuild power station in an emerging market may be very different.
Spot gas markets of any size are very unusual in such countries. In these markets prospective project lenders would be very likely to highlight a major volume risk in the area of fuel supply and seek to have it mitigated
Mitigating this volume risk
The most usual way of doing this is to seek a long-term fuel supply agreement (e.g. with the state gas company) which provides for:
* certainty of fuel supply over at least the life of the project loans – ideally with a “tail” of a few years after the loans are scheduled to be repaid;
* penalties in the event of:
o non-supply;
o supply of fuel of an inferior quality.
supply or pay contracts
penalties in the event of: o non-supply; o supply of fuel of an inferior quality.
can be very helpful in mitigating supply risk, but (as ever) their value is heavily dependent on the quality of the counterparty and the terms of the supply agreement itself. Once again, the “devil is in the detail”.
If does not supply the contracted volumes it will be obliged to pay pre-agreed penalties designed to cover the project’s fixed costs during the period of non-supply - including debt service.
Looking into the company behind supply or pay contracts
Need to look into:
Ability to supply
Creditworthiness
If company is in fact a substantial and well-established agricultural supply company with other sources of revenues and assets, and a creditworthy balance sheet, then its commitments under a supply agreement with substantial penalties for non-supply will have real value.
In cases where banks might accept weak supply contracts with weak penalties, the supplier normally:
- was a nationally owned entity with close commercial ties to the project company (perhaps as one of the sponsors in a joint venture project with an international company);
- had undoubted access to the gas or feedstocks required;
- had a strong track-record of meeting commitments to the letter or supplying an acceptable alternative.
Although banks may accept an apparently weak supply arrangement in such cases, a detailed review of the supply contract is still of course absolutely necessary.
termination clauses
Given the importance of eliminating volume risk, lenders will pay particular attention to the termination clauses and will want to keep the circumstances under which the supplier may terminate the contract down to a very short list. Clearly termination for non-payment by the SPV must be possible, but even here the lenders may seek some form of direct agreement with the supplier so that:
a) they are notified of any looming default by the SPV; and
b) have the right to step in and “cure” the default by making payments.
c) Another key area of documentary due diligence for the lenders will be the area of force majeure . A particular concern will be that the supplier might be able to claim FM – and thereby be relieved of some or all of his obligations under the supply contract – while the SPV will not be able to claim FM under its other contractual obligations.
Force Majeure
. These are, in general, happenings which are defined as being unforeseeable and beyond the control of the parties concerned.
Natural catastrophes or acts of god
Government actions - failure for a government to perform after its given a particular commitment
Political events such as war, strikes etc may also apply
Lenders trying to mitigate FM
The project SPV sits at the centre of a carefully-balanced risk allocation structure and – being a thinly- capitalised and highly-leveraged animal – it cannot afford to accept much in the way of new liabilities or costs. For this reason, lenders seek to be protected from the impact of FM events as far as possible, which is best achieved by protecting the SPV itself from FM events.
When undertaking FM contractual due diligence, lenders will try to ensure that:
- FM events in the project’s contracts are “symmetrical” wherever possible – thus if a power generation project’s construction contractor invokes FM, e.g., because of a strike at a supplier, the SPV should have the ability to call FM under any power sales agreement for the same cause, so that it does not incur penalties for non-performance under other contracts (such as O&M and fuel supply contracts);
- insurable FM events are properly insured;
- the impact of FM events which cannot be insured or where the cost of insurance would be excessive is tested by means of cashflow sensitivities – e.g. by running an interruption of operation sensitivity to model the impact of a prolonged strike.
When lenders accept reserve risk on a single asset (oil, gas, windfarm etc) they will insist that the reserves to which they give value are:
a. economically recoverable – resources which are present physically but whose cost of extraction would exceed the revenue they would generate do not qualify as reserves;
b. based on the highest probability level in terms of the level of ultimate production, which equates to the lowest predicted production volume.
European lenders calculation of bankable reserves:
Will be on a “probabilistic” analysis of likely production outcomes
the estimation of mineral reserves in particular requires values to be given to a large number of variables (rock permeability and porosity, water saturation in the reservoir, viscosity of the reservoir fluids etc.)
