Bordeaux Electrique is a utility company in southwest France that is required to meet local clean air emissions standards. In the past, Bordeaux Electrique has purchased emissions credits through bilateral, over-thecounter (OTC) trades. This year, Bordeaux Electrique has decided to buy credits through the European Climate Exchange (ECX). What is the main advantage of buying emission credits through an allowance exchange instead of through OTC deals? a. b. c. d.
Exchanges avoid the heavy taxation levied against OTC profits. There are more arbitrage opportunities available on allowance exchanges. Allowance exchanges eliminate counterparty risk. The European Union is mandating the shift from OTC to exchange-based systems for allowance trading.

The system operator ensures that all electric generating units on the transmission grid are maintained in accordance with system specifications. The system operator coordinates all activity on the distribution grid. The system operator coordinates the dispatch of generating units within the transmission pool. There is no need for a system operator in this case, since each member company independently plans and implements its own transmission network strategy.

A 3-month natural gas option with a strike of USD 6.00 on an August contract is trading at a Black-implied volatility of 45%. A call option with the same contract specifications, but a strike price of USD 6.50, is trading at a Black-implied volatility of 50%, producing a volatility smile. Which of the following conclusions can be made given the market information above? a. b. c. d.
The volatility smile indicates that the market is feeling good about the economy and prices are expected to go higher. The different volatilities for the call option positions indicate that the lognormal Black model cannot capture the true underlying price behavior with a single volatility measure. A third call option with the same contract specifications, but a strike price of USD 7.00 must therefore be trading at a Black-implied volatility of 55%. The two options should have exactly the same volatility, creating a market arbitrage opportunity: the USD 6.00 option is under-priced relative to the USD 6.50 option.

Akiko, an ERP, is pricing a daily transportation deal between Henry Hub and Houston Ship Channel using the mean-reverting Ornstein-Uhlenbeck process to model gas prices. In order to calculate the at-the-money (ATM) implied volatilities for Henry Hub and Houston Ship Channel Akiko will need to do which of the following? a. b. c. d.

Hydroelectric projects are not being pursued in many developed nations despite the fact they are an emissions-free source of power. What is the primary reason most developed countries are not building hydroelectric plants? a. b. c. d.
35.
Calculate the correct volatilities since the implied volatilities from a Black-Scholes calculation are not the same volatilities used in the Ornstein-Uhlenbeck process. Scale the implied volatilities by 365250 since it is a daily deal. Roughly estimate implied volatilities. Nothing else needs to be done. Scale the implied volatilities by 250365 since it is a daily deal.
National environmental regulations make the construction of new hydro projects extremely difficult. Without a global cap-and-trade emissions scheme, it is less-expensive to build fossil fuel-powered generation plants. Government incentives favor renewable projects like wind and solar over hydroelectric plants. Most developed nations have already largely exploited their hydroelectric potential.
Which of the following statements is true about extra heavy crude oils that typically have an ˚API below 15? a. b. c. d.
Extra-heavy oil is not considered genuine petroleum. Extra-heavy oils are not commercially viable. Reserves of extra-heavy oil are concentrated in North America. The total global resources of extra-heavy oils may be four times as large as the world’s proven reserves of conventional oils.

Electricity generation using wind power has experienced rapid growth during the past three decades. Which of the following statements regarding the use of wind energy is correct? a. b. c. d.
37.
Which of the following is a weakness in applying single-factor mean-reverting models in option valuation? a. b. c. d.
38.
The commercial wind energy industry in the United States grew rapidly in the 1980s, despite high production costs due to legislation and federal regulation. As wind velocity increases, the amount of electricity generated by a wind turbine also increases without limit. Thanks to their persistent on-shore wind flows, the states of the U.S. West Coast (California, Oregon, Washington) have dubbed themselves the “Saudi Arabia of Wind”. The average output of a wind turbine is usually only 25-40% of its rated output.
Black-equivalent volatility goes to zero with increasing time to expiration. Black-equivalent volatility increases with increasing time to expiration. The Black-equivalent volatility decreases with increasing time to expiration. Black-equivalent volatility is proportional to spot price volatility.

The relationship between cash and futures prices can vary due to systematic and unsystematic changes in basis. Which of the following is synonymous with characteristics of systematic changes in basis, leading to convergence between cash and futures price? a. b. c. d.
Delta Gamma Theta Vega
Correct answer: c Explanation: Answer c is correct because, both systematic basis and Theta have values that degrade with time. Since answer c is correct, all other answers are incorrect. We note that the Greeks are not discussed in the chapter, but from other readings the candidate should be able to understand that Theta degrades as time
to expiration diminishes and, likewise, so does systematic basis. Reading reference: Fundamentals of Trading Energy Futures & Options, 2nd Edition , Errera and Brown, Chapter 3, p.50.

Victor is a natural gas trader based in Chicago. He has just learned that a large coal-fired electricity generating plant in Pennsylvania will be shutting down for unplanned maintenance in a few days, increasing demand for natural gas to fuel backup plants. Victor plans to take advantage of this speculative opportunity by purchasing gas on the spot market, storing it briefly and then selling it when demand rises as the natural gas power plants come on line. This is an example of what kind of natural gas spread trade? a. b. c. d.
Location Heat Rate Time Swing
Correct answer: d Explanation: Swing trades rely on a trader’s ability to store gas for short periods of time, allowing them to “buy low and sell high” by delivering the gas on the spot market when demand is high. Time spreads are simultaneous buy/sells of future, forward, or swap contracts with differing maturity dates; winter vs. spring,
for example. Similarly, a locational spread is a simultaneous buy/sell at different locations with the same maturity while a heat rate is a simultaneous buy/sell of power and gas matching either the spread trading in the market or the underlying heat rate of a physical plant.

Heinz provides risk management support to a multinational energy trading desk. His primary responsibility is to inform the Chief Risk Officer about derivatives trades executed each day along with all trader risk limit exceptions. Which of the following risk control categories best describes Heinz’s primary responsibility? a. b. c. d.
Risk Risk Risk Risk
Reporting Review Assessment Control
Correct answer: a Explanation: Reporting derivatives positions to upper management is a duty that falls under the reporting (communications) category of risk control; it is an important aspect of risk management because if upper management is not informed of derivative usage the effects on the company can be devastating. Daily
reporting of derivative positions is not the same as an in-depth internal review of a company's finances or an audit, thus b is not the correct answer; nor do the reporting duties fall under the risk assessment or management control categories.

Andrew Willingham, ERP, is modeling the volatility of WTI forward contract prices using a single-factor log-of-price mean reverting model. What will the output from the model indicate about the correlation between spot and forward price returns assuming the initial price level in the spot and forward market are equal? a. b. c. d.
Correlation will remain perfect across all points between the front and back-end of the forward price curve. Correlation will decrease between the front and back-end of the forward price curve. Correlation will increase between the front and back-end of the forward price curve. Correlation will fluctuate due to seasonality.
Correct answer: a Explanation: Single factor models assume all factors move in tandem. Assuming the initial price level for spot
and forward prices are equal, the correlation between spot and forward price returns will remain perfect between the front and back-end of the forward price curve. Reading reference: Energy Risk: Valuing and Managing Energy Derivatives, Pilipovic, Chapter 8, page 234-236.

Karachaganak, Kazakhstan is one of the largest gas condensate fields in the world, with proven reserves of 1.9 billion barrels of oil and 13 trillion cubic feet of gas. In 2004, the field produced about 220,000 barrels of oil and 1.3 billion cubic feet of gas per day. What is the producing gas-oil ratio? a. b. c. d.
4,300 5,909 6,842 7,523
Correct answer: b Explanation: Answer b is correct. The definition of producing gas-oil ratio requires gas production (in cubic feet) to be divided by oil production (in barrels). Thus, GOR = (1,300,000,000 cf)/(220,000 bbl) = 5,909. Note that the gas-oil ratio of the proved reserves is computed as (13 Tcf)/(1.9 Bbbl) = 6,842 which denotes a
field with oil (condensate) and gas production. Reading reference: Nontechnical Guide to Petroleum Geology, Exploration, Drilling, and Production, 2nd Edition , Hyne, Chapter 1, page 11.

Two manufacturing plants — Factory Alpha and Factory Bravo — are told by the government they each need to reduce their greenhouse gas emissions. The target reductions and expenses required to meet this goal for each factory are shown in the table below.
Required emissions reductions Cost of emissions reductions Total cost of reductions
Alpha
Bravo
10 tons USD 120 per ton USD 1,200
10 tons USD 40 per ton USD 400
Under an emissions trading scheme, Factory Alpha can pay Factory Bravo to reduce its emissions by an additional 10 tons, in effect, buying the needed emissions credit from Bravo. What will Bravo’s final emission reduction cost be if it charges Alpha USD 600 for the emissions credit? a. b. c. d.
USD USD USD USD
200 600 800 1,000
Correct answer: a Explanation: By making the deal with Factory Alpha, Factory Bravo’s total cost of reductions will be USD 200 (answer a). Bravo will now have to reduce their emissions by 20 tons, at USD 40 per ton; this will cost Bravo USD 800. Bravo will receive a payment from Alpha of USD 600, making their final costs USD 200 (800 — 600 = 200). Reading reference: The Handbook of Commodity Investing , Fabozzi, Chapter 37.

Although the industry has known about shale gas resources for decades, the resources have only recently become the focus of serious commercial exploration and production activities. What characteristic of shale gas has historically made exploration and production uneconomical? a. b. c. d.
Shale Shale Shale Shale
has low natural permeability. is an extremely dense rock that is difficult to drill through. gas is typically “wet,” requiring extensive processing. reserves tend to be in remote, hard-to-access locations.
Correct answer: a Explanation: The correct answer is a. Shale naturally has low permeability, meaning only a small amount of a reservoir is able to flow towards a drilled hole. Improvements in hydraulic fracturing technology and techniques, which open fissures within the shale allowing for the free flow of gas, have made shale reserves commercially
viable, making a the correct answer. Many shale reserves in the United States are near population and natural gas consumption centers, while shale gas is not “typically” wet, but in the cases of wet gas, these hydrocarbons can form an important revenue stream.

simple, Y = complex, Z = very complex simple, Y = very complex, Z = complex complex, Y = simple, Z = very complex very complex, Y = complex, Z = simple
Correct answer: d Explanation: Answer d is correct. Refinery complexity refers to the capacity and type of processing units that comprise a refinery. Refinery complexity will increase when “complex” units with large capacity are added since they have greater ability to convert (heavy) crude input into gasoline. For a given grade of crude oil (in
this case, medium sour, heavy), as the complexity of the refinery increases the gasoline yield increases and the residual fuel yield decreases (the residual fuel stream is being converted to gasoline).

High operating costs and operational constraints make which of the following types of facility the least desirable option for underground natural gas storage? a. b. c. d.
Depleted oil and gas fields Aquifers Salt caverns Storage tanks
Correct answer: b Explanation: Answer b is correct. Aquifers are considered the least desirable underground storage facility for several reasons — the geology of the aquifer is usually not well understood, infrastructure (wells, pumps, compressors, etc.) is unavailable at the site, greater injection pressures mean higher operating cost, gas will need to be dehydrated, and more stringent environmental regulations will be in place.

a.
USD 0.0125/kWh USD 0.1250/kWh USD -0.0125/kWh USD -0.1250/kWh
b. c. d.
Correct answer: c Explanation: Answer c is correct, the calculation for determining the spark spread in this scenario is as follows:
Spark Spread = Output Price — Input Price Output Price = USD 30/MWh x 1MWh/1000kWh = USD 0.03/kWh Input Price = 8500 Btu/kWh x USD 5/1,000,000Btu = USD 0.0425/kWh Therefore, the Spark Spread = -0.0125 Reading reference: Managing Energy Price Risk , Kaminski, Chapter 3, page 120.

High pressure in subsurface reservoirs can cause a significant volume of natural gas to be dissolved in underground crude oil reserves. Which of the following is the correct term for this build-up of gas? a. b. c. d.
Non-associated gas Crude oil gas Associated gas Working gas
Correct answer: c Explanation: Answer c is correct. Because of high pressure in the subsurface reservoir, a considerable volume of natural gas can be dissolved in crude oil. The formation, dissolved or solution gas/oil ratiois the cubic feet of natural gas dissolved in one barrel of oil in that reservoir under subsurface conditions. The volume measurements are reported under surface conditions. In general, as the pressure of the reservoir increases
with depth, the amount of natural gas that can be dissolved in crude oil increases. When crude oil is lifted up a well to the surface, the pressure is relieved, and the natural gas, called solution gas, bubbles out of the oil. The producing gas-oil ratio (GOR) of a well is the number of cubic feet of gas the well produces per barrel of oil. Non-associated natural gasis gas that is not in contact with oil in the subsurface. A non-associated gas well produces almost pure methane. Associated natural gas occurs in contact with crude oil in the subsurface. It occurs both as gas in the free gas cap above the oil and gas dissolved in the crude oil.

Claudio has been put in charge of developing a site for a new nuclear power plant. Because of the disaster in Fukushima, Japan, public sentiment has turned against nuclear power at this location. For this reason, Claudio is recommending the construction of a pebble-bed modular reactor (PBMR). What is the main advantage of the PBMR? a. b. c. d.
The PBMR does not use uranium as fuel. PMBRs are considered safe because they cannot “melt down” like other designs. PBMRs produce more electricity than other similarly-sized reactor designs. Unlike other reactor designs, PBMRs do not generate high levels of heat.
Correct answer: b Explanation: Thanks to their design, PBMRs will shut down if operating temperatures get too high, meaning
that a core meltdown, as nearly happened in the Three Mile Island incident, is impossible, thus b is the correct answer. PBMRs still use uranium as fuel, generate high temperatures to produce steam to drive a turbine to generate electricity, and a PBMR does not produce more electricity than other designs, in fact PBMRs are typically smaller (per unit) than PWRs and BWRs.

Andreas purchased a monthly 100 MW on-peak power call option for a month that has 20 business days. The strike price is USD 75/MWh and the premium is USD 5/MWh. What would the gross settlement amount be if Andreas exercised the call option in a month when the average on-peak power price was USD 85/MWh? a. b. c. d.
USD 160,000 USD 240,000 USD 320,000 USD 480,000
Correct answer: c Explanation: The correct answer is c; the payoff does not include the amount of premium (32,000 MWh x USD 85 –USD 75). Payout is max(St — k,0) x Q, wherein Q = quantity. Answer a is incorrect, because it includes the premium cost of USD 160,000 (i.e. 32,000 MWh x USD 5). Answer b is incorrect, because it
assumes an all-day usage of 48,000 MWh and thus a premium cost (48,000 MWh x USD 85 — USD 75-USD 5); while answer d is incorrect, because it assumes 48,000 MWh (48,000 MWh x USD 85 –USD 75). Assumes candidates will know on-peak power call option means for 16 hours per day.

Makati and Sons Heating Oil Company expects customer demand to average 2,200 gallons of heating oil during the upcoming heating season. The company sells oil to customers using fixed price contracts and has decided to store enough oil to meet average customer demand of 2,300 gallons. They have also purchased call options to protect against the risk of a much colder than expected winter. What risk is the company primarily seeking to hedge? a. b. c. d.
Volume Risk Supply Risk Credit Risk Location Basis Risk
Correct answer: a Explanation: Answer a is correct, the heating oil company is concerned about a colder than expected winter,
but does not want to be stuck with an excess of inventory. Call options allow the company to purchase additional inventory at a set price should temperatures drop below normal, the options can expire unused if the winter temperatures are at a normal level.

On June 20, Caufield Refining estimates it will need to purchase 40,000 barrels of crude on October 12. Caufield decides to hedge price risk using a November NYMEX futures contract. The November futures price on June 20 is USD 67.00/bbl. On October 12, Caufield is ready to purchase its required crude oil and closes out the futures contract on that day; at this time the spot price is USD 70.10/bbl and the futures price is USD 68.50/bbl. In this scenario, what is the effective price paid per barrel? a. b. c. d.
USD USD USD USD
68.50 68.60 70.10 70.40
Correct answer: b Explanation: The effective price paid (in dollars per barrel) is the final spot price less the gain on the futures, or
70.10 — 1.50 = 68.60. This can also be calculated as the initial futures price plus the final basis, 67.00 + 1.60 = 68.60. Reading reference: Fundamentals of Trading Energy Futures & Options, Errera and Brown, Chapter 3, page 43-44.

Steve Dolan is a power manager at Upstate Electric. He is negotiating a one-day contract to sell 100 MW of electricity at USD 55/MWh for a 24-hour period and has been asked to calculate the Value-at-Risk (VaR) for the contract. If the daily volatility of electricity prices is 2%, what is the daily VaR on the contract assuming a 95% confidence interval? a. b. c. d.
USD USD USD USD
180 3,447 4,330 5,412
Correct answer: c Explanation: Answer c is correct. The correct application of the VaR calculation in this case is the lot size multiplied by the hourly rate multiplied by the time period of the contract multiplied by the daily volatility
measurement multiplied by the confidence level factor, which in this case is: 100 x 55 x 24 x .02 x 1.64 = USD 4,330. Since the contract is for one day, no time adjustment is needed. Reading reference: Price Risk Management in the Energy Industry: The Value at Risk Approach, Mauro, Section 6.

Neptune Gas Exporters receives natural gas streams from several fields, each with a different heating content. Prior to distributing the gas through pipelines, Neptune blends the gases to ensure the exported gas is within a consistent heating range (expressed in Btu content per cubic foot). Neptune’s blended gas should fall into what heating range? a. b. c. d.
500 to 800 Btu/cf 900 to 1,200 Btu/cf 1,200 to 1,500 Btu/cf 1,500 to 1,800 Btu/cf
Correct answer: b Explanation: Answer b is correct. Almost all gas produced in the world has a heat content that ranges between 900 and 1200 Btu per cubic foot. Natural gases produced in association with crude oil will typically
have a higher Btu content, because the gas is in contact with crude oil and “absorbs” some of the heavier components in the crude oil. Non-associated natural gas and gases with a high CO 2 content and related impurities will have a lower Btu content due to the dominance of methane and because most impurities do not burn, thus reducing the heat content.

Bordeaux Electrique is a utility company in southwest France that is required to meet local clean air emissions standards. In the past, Bordeaux Electrique has purchased emissions credits through bilateral, over-thecounter (OTC) trades. This year, Bordeaux Electrique has decided to buy credits through the European Climate Exchange (ECX). What is the main advantage of buying emission credits through an allowance exchange instead of through OTC deals? a. b. c. d.
Exchanges avoid the heavy taxation levied against OTC profits. There are more arbitrage opportunities available on allowance exchanges. Allowance exchanges eliminate counterparty risk. The European Union is mandating the shift from OTC to exchange-based systems for allowance trading.
Correct answer: c Explanation: In the newly-developing emissions allowance market, often buyers and sellers have no previous knowledge of one another, making credit, or counterparty, risk a major concern in their transactions; trades
executed through an exchange eliminate this risk, making c the correct answer. Reading reference: Handbook of Commodity Investing, Fabozzi (ed.), Chapter 37, page 849.

Which of the following statements correctly defines the role of a system operator in an electric transmission network? a. b. c. d.
The system operator ensures that all electric generating units on the transmission grid are maintained in accordance with system specifications. The system operator coordinates all activity on the distribution grid. The system operator coordinates the dispatch of generating units within the transmission pool. There is no need for a system operator in this case, since each member company independently plans and implements its own transmission network strategy.
Correct answer: c Explanation: While the system operator has many responsibilities, the one listed in answer c is the only correct one of the alternatives listed. Answer a is incorrect, since the system operator does not play a role in maintaining the condition of generation units. Answer b is incorrect since the system operator manages the
transmission network, not the distribution network. Answer d is incorrect, since PJM and other pools have a system operator. Doing otherwise could result in “gaming”, due to a lack of an independent party. Reading reference: Making Competition Work , Hunt, Chapter 2, pages 20-21.

A 3-month natural gas option with a strike of USD 6.00 on an August contract is trading at a Black-implied volatility of 45%. A call option with the same contract specifications, but a strike price of USD 6.50, is trading at a Black-implied volatility of 50%, producing a volatility smile. Which of the following conclusions can be made given the market information above? a. b. c. d.
The volatility smile indicates that the market is feeling good about the economy and prices are expected to go higher. The different volatilities for the call option positions indicate that the lognormal Black model cannot capture the true underlying price behavior with a single volatility measure. A third call option with the same contract specifications, but a strike price of USD 7.00 must therefore be trading at a Black-implied volatility of 55%. The two options should have exactly the same volatility, creating a market arbitrage opportunity: the USD 6.00 option is under-priced relative to the USD 6.50 option.
Correct answer: b Explanation: Answer b is correct. Black-implied volatilities for options with the same contract specifications but different strikes are necessary to capture the true underlying price behavior and therefore traded option
prices. Black option pricing model assumes log-normal price behavior for the underlying forward prices, which generally does not capture the full spectrum of behavior of energy prices given a single volatility measure. Reading reference: Energy Risk , Pilipovic: Chapter 8, page 232.

Colin is the procurement manager for a regional heating oil distributor in Alberta, Canada. In September, Colin notices the 3-month forward price for heating oil is trading at CAD 4.65 per gallon — a price that appears too high relative to current market economics. Given a spot price of CAD 4.00 per gallon, a monthly storage cost of CAD .05 per gallon and annual risk-free interest rate of 4.25%?
28.
What would the net realized profit/loss per gallon be in 3 months if Colin executed a transaction to take a dvantage of a perceived mispricing between the spot and forward markets? a. b. c. d.
CAD CAD CAD CAD
-0.03 per gallon 0.12 per gallon 0.46 per gallon 0.61 per gallon
Correct answer: c Explanation: Answer c is correct because, it properly accounts for cash and carry — the forward is too high,
so Colin should buy the spot and short the forward. All other answers are incorrect. FV of Spot = CAD 4.00 *(1.0107) = 4.0428 FV of Storage = .05 + .05 * (1.0035)^1 + .05 * (1.0035)^2 = .1506Total FV = 4.19 Forward Price of CAD 4.65> FV of Spot (including storage) CAD 4.19 Arbitrage profit by buying spot, storing, and selling forward short = .46 Reading reference: Fundamentals of Derivatives Markets , McDonald, Chapter 6, pages 181-183.

Roger has constructed a portfolio of crude oil option contracts that he has delta hedged. Over a one month period, Roger observes that his portfolio is not performing as expected and he is concerned that the change in portfolio delta, relative to the change in the underlying price of oil, is too high. Which of the following port folio risk characteristics should Roger neutralize so that his hedge strategy more effectively responds to changes in the underlying price of oil? a. b. c. d.
Beta Gamma Theta Vega
Correct answer: b Explanation: The correct answer is b. Roger’s delta hedge will not perform as well as expected as price of the
underlying assets diverge from the prices of the options in his portfolio. The way to counteract this trend is to attempt to neutralize the sensitivity of the portfolio to the change in price between the option and the underlying. This sensitivity is known as gamma, answer b. Reading reference: Energy Derivatives, Clewlow and Strickland, Chapter 9, pages 169-173.

Akiko, an ERP, is pricing a daily transportation deal between Henry Hub and Houston Ship Channel using the mean-reverting Ornstein-Uhlenbeck process to model gas prices. In order to calculate the at-the-money (ATM) implied volatilities for Henry Hub and Houston Ship Channel Akiko will need to do which of the following? a. b. c. d.
Calculate the correct volatilities since the implied volatilities from a Black-Scholes calculation are not the same volatilities used in the Ornstein-Uhlenbeck process. Scale the implied volatilities by 365250 since it is a daily deal. Roughly estimate implied volatilities. Nothing else needs to be done. Scale the implied volatilities by 250365 since it is a daily deal.
Correct answer: a Explanation: Answer a is correct. Volatility has to be estimated in the context of the stochastic process Black-Scholes model. The volatility for the Ornstein-Uhlenbeck process has units of dollars. The volatilities in
Black-Scholes and Ornstein-Uhlenbeck are not interchangeable. Reading reference: Energy Derivatives: Pricing and Risk Management , Clewlow and Strickland, Chapter 3.2.2, page 41.

Hydroelectric projects are not being pursued in many developed nations despite the fact they are an emissions-free source of power. What is the primary reason most developed countries are not building hydroelectric plants? a. b. c. d.
National environmental regulations make the construction of new hydro projects extremely difficult. Without a global cap-and-trade emissions scheme, it is less-expensive to build fossil fuel-powered generation plants. Government incentives favor renewable projects like wind and solar over hydroelectric plants. Most developed nations have already largely exploited their hydroelectric potential.
Correct answer: d Explanation: While all are factors, d is the major reason. With the exception of Canada, most developed nations have already constructed hydroelectric plants at suitable sites within their national borders. Much of
the future growth in hydropower will come from developing nations like China, Indonesia and Brazil. Reading reference: Renewable Energy in Nontechnical Language, Chambers, Chapter 6, pages 150-152.

Which of the following statements is true about extra heavy crude oils that typically have an ˚API below 15? a. b. c. d.
Extra-heavy oil is not considered genuine petroleum. Extra-heavy oils are not commercially viable. Reserves of extra-heavy oil are concentrated in North America. The total global resources of extra-heavy oils may be four times as large as the world’s proven reserves of conventional oils.
Correct answer: d Explanation: According to the text, extra-heavy resources are four times the proven reserves of conventional oil, making d the correct answer. Answer a is incorrect as per the text, extra-heavy oil is genuine petroleum;
extra-heavy oils are currently produced commercially in Canada and Venezuela, making b incorrect; and while North America has large extra-heavy reserves, so too do Russia, Venezuela and Indonesia, making c incorrect as well.

Electricity generation using wind power has experienced rapid growth during the past three decades. Which of the following statements regarding the use of wind energy is correct? a. b. c. d.
The commercial wind energy industry in the United States grew rapidly in the 1980s, despite high production costs due to legislation and federal regulation. As wind velocity increases, the amount of electricity generated by a wind turbine also increases without limit. Thanks to their persistent on-shore wind flows, the states of the U.S. West Coast (California, Oregon, Washington) have dubbed themselves the “Saudi Arabia of Wind”. The average output of a wind turbine is usually only 25-40% of its rated output.
Correct answer: d Explanation: Answer d is correct; when times of insufficient wind flow, downtime for maintenance, etc., are factored in, a turbine usually only produces 25-40% of its rated capacity. Answer a is incorrect, the Public
Utilities Regulatory Policies Act (PURPA) actually spurred a major investment in wind production in California that led to nationwide expansion; answer b is incorrect, wind turbines must shut down during times of high wind speed to avoid causing damage to the turbine structure or to the turbine itself; answer c is also incorrect, the states of the U.S. Great Plains, not the West Coast, have dubbed themselves the “Saudi Arabia of Wind”.

Which of the following is a weakness in applying single-factor mean-reverting models in option valuation? a. b. c. d.
Black-equivalent volatility goes to zero with increasing time to expiration. Black-equivalent volatility increases with increasing time to expiration. The Black-equivalent volatility decreases with increasing time to expiration. Black-equivalent volatility is proportional to spot price volatility.
Correct answer: a Explanation: Implementing single factor mean-reverting models for option valuation can be very dangerous if
pricing long-term options. Single factor mean-reversion forces price distributions to stop growing in width as time to expiration gets large, resulting in effective volatility of the option to move toward zero over its life time. Hence the correct answer is a. Reading reference: Energy Risk , Pilipovic, Chapter 5, pages 105-09.

Assume that a call option on natural gas with a strike price of USD 5.60/MMBtu has a vega of 1.0893. What would be the vega of a put option with the same strike price assuming the current price of natural gas is USD 5.80/MMBtu and the current risk-free interest rate is 2.5%. -1.0893 b. 0.0893 c. 1.0893 d. There is not enough information to compute vega. a.
Correct answer: c Explanation: Answer c, 1.0893, is correct. Vegas for puts and calls with the same strike price will be the same. This answer follows from the put/call parity relationship. Reading reference: Energy Derivatives: Pricing and Risk Management , Clewlow and Strickland, Chapter 9,

Consider the following two option contracts: • •
Option 1: January 2012 daily call, strike price of USD 30, call value of USD 5.45 Option 2: January 2012 monthly call, strike price of USD 33, call value of USD 6.00
What is the biggest challenge in estimating the implied volatility for these two contracts assuming the following parameters? • • •
Valuation date: 11/10/2011 Risk free rate: 4% Underlying value: USD 28
a.
The options are based on different time intervals (daily vs. monthly). The option quotes have different strike prices. The option quotes are both for call options. Winter power options are highly volatile due to seasonality factors.
b. c. d.
Correct answer: a Explanation: Reconciling the daily volatility of Option 1 with the monthly volatility of Option 2 can make it
very difficult to select the right parameters in the modeling process. The volatilities will tend to be correlated but different. Reading reference: Energy Risk , Pilipovic, Chapter 8, pages 226-228.

An August natural gas futures contract is currently priced at USD 5.60. You have been asked to structure a costless collar for a client who consumes natural gas and expects natural gas prices to rise. The following option quotes for calls and puts on August natural gas futures are currently available: Strike (USD)
Call Price (USD)
Put Price (USD)
5.650 5.625 5.600 5.575 5.525
0.31 0.32 0.34 0.35 0.37
0.36 0.35 0.34 0.32 0.30
Considering the information above, which one of the following portfolios would you suggest for your client? I. II.
A short call with a strike of 5.575 and a long put with a strike of 5.625 A long call with a strike of 5.625 and a short put with a strike of 5.575
a.
Portfolio I only Portfolio II only Either portfolio Neither portfolio
b. c. d.
Correct answer: b Explanation: A costless collar is formed with a long out of the money call and a short out of the money put
so that the premium paid for the call and the premium received for selling the put equal to zero. In this case only portfolio II qualifies as a costless collar. Reading reference: Managing Energy Price Risk , Kaminski, Chapter 2, pages 68-72.
