The volatility smile tells us that the market is feeling good about the economy and prices are expected to go higher. The different volatilities for the two call options tell us that the lognormal Black model cannot capture the true underlying price behavior with a single volatility measure. A call option with the same contract specifications as the two options in the problem but with a strike of USD 7.00 must therefore be trading at a Black-implied volatility of 55%. The two options should have exactly the same volatility, and therefore this is a case of market arbitrage: the USD 6.00 option is under-priced relative to the USD 6.50 option.

Devon is interested in creating a synthetic commodity by combining a forward contract with a zero-coupon bond. What is the payoff required on the zero-coupon bond if the annual risk-free interest rate on a continuous basis is 2% and the price of the commodity forward contract at time 0 is F0,T = USD 150 (where T = 1 year)? a. b. c. d.

USD USD USD USD

147 150 153 156

Correct answer: b Reading reference: Fundamentals of Derivatives Markets, McDonald, Chapter 6, p.171. Explanation: Answer b is correct because, in creating a synthetic, we enter into a commodity forward contract and purchase a zero coupon bond equaling e-rt* F0,T, this value is USD 147. The payoff is USD 150. The total payoff in formula form is: ST — F0,T + F0,T, or the payoff on the forward + the payoff of the zero bond. Answer a is incorrect because it is the investment, at time 0, in the zero bond.

The Senior Management of Cristal Crude Refinery is planning to build a new refinery complex in Indonesia that includes a coker. Which of the following is true about the new refinery? a. b. c. d.

The The The The

refinery refinery refinery refinery

is a hydroskimming refinery. is classified as a simple refinery. is best suited for processing heavy crude oil. will produce nearly as much residual fuel as gasoline.

Correct answer: c Reading reference: Petroleum Refining in Nontechnical Language, 3rd Edition, Leffler: Chapter 20. Explanation: The presence of a coker defines this as a “very complex” refinery; very complex refineries usually make their best margins in processing heavy crude, which the coker allows them to break down into more desirable light petroleum products. Very complex refineries produce little or no residual fuel oil. By comparison, hydroskimming refineries are classified as “simple refineries” that do not include cokers and usually cannot profitably refine heavy crude. Since you know your refinery includes a coker, this means that answer b is correct.

4.

Which of the following statements regarding the transportation of petroleum products is correct? a. b. c. d.

Natural gas liquids like ethane, ethane-propane mixtures and LPGs are commonly transported by dedicated pipeline. Contamination is usually an issue when butane is transported via the same pipeline as gasoline and diesel. Ethane-propane mixtures are seldom transported via pipeline. Natural gasoline is typically transported through its own dedicated pipeline.

Correct answer: a Reading reference: Fundamentals of Natural Gas Processing, Kidnay and Parish, Chapter 12, p. 261. Explanation: Answer a is correct; LPGs are typically transported through their own product-specific pipelines.

Which of the following best describes a royalty payment? a. b. c. d.

An amount equal to a percentage of the value of production paid by the holder to the State in cash or in kind. An amount paid by the contract holder to an independent agent for the right to exploit an asset. The money collected by the site inspector. A tax on production volume, independent of profits.

Correct answer: a Reading reference: Oil, Gas Exploration and Production, Institut Francais: Chapter 3, p. 198-200. Explanation: A royalty is an amount equal to a percentage of the value of production, paid by the holder to the State in cash or in kind. It is effectively a tax directly proportional to the value of production, that is, a tax on turnover, and independent of profits. The amount of the royalty depends not only on the percentage applying, but also on a number of other parameters which must be carefully specified.

6.

Which of the following energy forward contracts will have the greatest mark-to-market sensitivity to a singleday price spike created by an unplanned outage at a large generation plant during the delivery period? a. b. c. d.

5 x 16 contract for a week On-peak contract for delivery over the entire month Round-the-clock contract for delivery over a two-month period A 5 x 8, 2 x 2 4 calendar year contract

Correct answer: a Reading reference: Energy Risk, Pilipovic: Chapter 7, p. 173-179. Explanation: A forward contract for delivery over a number of days is valued as a weighted average of the daily forward prices, be it the on-peak, off-peak, or round-the-clock prices given the contract specifications. Hence, a price spike expected to occur for just one of the days in the period will have the greatest impact on the shorter time period of delivery. That would make answer a the best answer above. Additionally, on-peak markets (5 x 16) tend to be more volatile than the round-the-clock markets (7 x 24), which further tend to be more volatile than the off-peak markets (5 x 8,2 x 24). Hence, in this regard, a is also the best answer.

Heinz provides risk management 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 Reading reference: Energy Markets: Price Risk Management and Trading, Tom James; Chapter 10, p. 183-84. 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.

A power plant enters into a natural gas contract that has a take-or-pay value of 85% and a swing value of 20%. If the contract specifies delivery of 120 MWh of natural gas equivalent, what is the minimum amount of gas that must be purchased under the of the contract? a. b. c. d.

24 MWh 96 MWh 102 MWh 120 MWh

Correct answer: c Reading reference: Managing Energy Risk: An Integrated View on Power and Other Energy Markets, Burger, Graeber, and Schindlmayer, Chapter 4, p. 166-177. Explanation: The take-or-pay percentage refers to the percentage of the contract that must be paid for whether the importer wants to take delivery of the gas or not. For this contract, the minimum that must be paid for is 85% x 120 MWh = 102 MWh.

10.

Consider the delta profile for at-the-money European call forward options on NYMEX crude oil. What is the approximate delta value when the strike price is close to the forward price? a. b. c. d.

0.00 0.25 0.50 1.00

Correct answer: c Reading reference: Energy Derivatives: Pricing and Risk Management, Clewlow and Strickland; Chapter 9, p. 166. Explanation: Answer c is correct. For at-the-money options, where the strike price is close to the forward price the delta is approximately 0.5.

11.

Which of the following is NOT a method for managing credit-risk exposure within energy markets? a. b. c. d.

Clearing OTC energy derivatives Obtaining credit risk insurance Purchasing commodity forward contracts Securing a financial guarantee via an Irrevocable Standby Letter of Credit

Correct answer: c Reading reference: Energy Markets: Price Risk Management and Trading, James: Chapter 16, p. 319-21. Explanation: Methods for managing credit-risk exposure include: master netting; collateralization; financial guarantees; credit insurance; credit derivatives; assignment; and clearing OTC energy derivatives. The purchase of commodity futures is a hedging strategy.

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 Reading reference: Norman J. Hyne. Nontechnical Guide to Petroleum Geology, Exploration, Drilling, and Production, 2nd Edition (Tulsa, OK: PennWell, 2001): Chapter 1, p. 11. 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.

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 Reading reference: Energy and Emissions Markets: Collision or Convergence?, James and Fusaro; Chapter 3, p. 31-32. 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).

You have been asked by your supervisor to hedge a daily power option. Which is the most appropriate contract to use to hedge the daily option? a. b. c. d.

Daily forward contract Daily futures contract OTC swap contract Balance-of-the-month contract

Correct answer: d Reading reference: Fundamentals of Electricity Derivatives, Kaminski: Chapter 2, p. 60, 70. Explanation: Most power markets, except perhaps the Nord Pool, do not have liquid markets for daily forward or futures contracts, so it is best to use a balance-of-the-month contract as a surrogate for daily forward/futures contracts to hedge daily options. The balance-of-the-month price is the price of power delivered every day from today until end of current month.

Which of the following is NOT a disputable point in the performance of an energy commodity contract? a. b. c. d.

Credit ratings Missed deliveries or deadlines Poor commodity quality Default on a debt

Correct answer: a Reading reference: Fundamentals of Electricity Derivatives, Kaminski; Chapter 12, p. 348-9. Explanation: Answer a is correct. Events and disputes that may come up with a physical contract include force majeure, the quality of the commodity being delivered, default on a debt, missed payments, or missed deliveries. Credit ratings are not created in a contract but rather via third parties.

Which of the following statements is/are true about the impact of a “Smart Grid”? I. II.

a. b. c. d.

A smart grid is a more flexible control system that maximizes the utility of existing transmission assets and delays the need for creating new ones. A smart grid provides better control of the transmission system allowing peaker plants to run during periods of congestion I only II only Both I and II are correct Neither I or II are correct

Correct answer: a Reading references: US Department of Energy, “The Smart Grid: An Introduction”. Explanation: Answer a is correct: statement I is true because newer technology will allow better rerouting of excess power in constrained zones through underutilized transmission assets, while statement II is false because through better utilization of transmission lines during congestion, peaker plants within congested areas will not have to run just to meet the demand.

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 Reading reference: Petroleum Refining in Nontechnical Language, 3rd Edition, Leffler: Chapter 20, p. 196. Explanation: 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).

Which facility type is usually considered the least desirable option for underground storage of natural gas because of expense and operational constraints? a. b. c. d.

Depleted oil and gas fields Aquifers Salt caverns Storage tanks

Correct answer: b Reading reference: Fundamentals of Natural Gas Processing, Kidnay and Parrish: Chapter 12, p. 257. Explanation: 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.

22.

Consider a power grid where the average heat rate for combined cycle gas turbine plants using natural gas is 8,500 Btu/kWh. The price of natural gas is USD 5.00/MMBtu, and the price of electricity is USD 30.00/MWh. What is the spark spread for this particular power grid? a. b. c. d.

USD USD USD USD

0.0125/kWh 0.1250/kWh -0.0125/kWh -0.1250/kWh

Correct answer: c Reading reference: Vincent Kaminski (ed). Managing Energy Price Risk, Chapter 3, p.120. Explanation: Answer c is correct, the calculation 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

Simone is interested in capturing large price swings in her energy portfolio and decides to use the delta-normal approach to compute portfolio VaR. The delta-normal approach will be least likely to capture large price changes in which of the following instruments? a. b. c. d.

Futures Forwards Swaps Options

Correct answer: d Reading reference: Energy Risk Management: A Non-technical Introduction to Energy Derivatives, Leppard; Chapter 4, p. 200-205. Explanation: d is correct. Since the delta-VaR method is a linear approximation, it works well only if a given portfolio is linear or close to linear. The term linear portfolio means that it consists of products that depend linearly on the risk factor changes. For example, a portfolio consisting of futures, forward and swaps is a linear portfolio. On the other hand, if there are many options in the portfolio it may be far from being linear. In fact, an energy portfolio is expected to be very nonlinear, especially if there are many asset-type deals (e.g. storage, generation, load service, and so on). In this case, linear approximation may be missing big changes in the portfolio values due to nonlinearity. Hence, delta-VaR method may yield inaccurate results for an energy portfolio consisting of options, since they are not linear instruments.

Which of the following statements regarding LNG project costs is correct? a. b. c. d.

The construction of liquefaction plant facilities typically represents the LNG chain’s most significant capital investment. LNG storage tank costs are independent of liquefaction plant location. The cost of a liquefaction plant is considered part of the upstream costs. One unusual aspect of LNG upstream and downstream development is that future additions to achieve economies of scale are not planned due to the high cost of building LNG facilities.

Correct answer: a Reading reference: LNG: A Nontechnical Guide, Tusiani: Chapter 11, p. 301. Explanation: Answer a is correct; it is generally the most significant capital item. Answer b is incorrect, since storage tank costs are dependent on location, as well as, total production, distance from market and tank system design. The cost of a liquefaction plant are downstream, therefore, answer c is incorrect. Answer d is incorrect, since future additions are anticipated and undertaken if sufficient reserves are present.

A major hurricane has shut down drilling activity on hundreds of oil rigs across the Gulf of Mexico. The resulting supply disruption has caused the cash (spot) price of WTI crude to spike above the price of longer dated futures contracts. As a result the WTI contract is said to be trading in _____________. a. b. c. d.

backwardation contango short-term disequilibrium extreme volatility

Correct answer: a Reading reference: Risk Management in Commodity Markets, Geman: Chapter 2, p. 11. Explanation: Answer a is correct. A market in backwardation (inverted market) is characterized by cash (spot) prices that are higher than longer dated futures contracts. In contrast, a market in contango is characterized by an upward sloping forward price curve.

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 Free gas

Correct answer: c Reading reference: Nontechnical Guide to Petroleum Geology, Exploration, Drilling, and Production, Hyne: Chapter 1, p. 11. Explanation: b 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 gas is gas that is not in with oil in the subsurface. A non-associated gas well produces almost pure methane. Associated natural gas occurs in 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.

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 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 USD USD USD

160,000 240,000 320,000 480,000

Correct answer: c Reading reference: Managing Energy Price Risk, Kaminski: Chapter 2, p. 46. Explanation: The correct answer is c: the payoff does not include the amount of (32,000 MWH x USD 85 - USD 75). Payout is max (St — k,0) x Q, wherein Q = quantity. a is incorrect, because it includes the cost of USD 160,000 (i.e. 32,000 MWH x USD 5). b is incorrect, because it assumes all-hours of 48,000 MWH and cost (48,000 MWH x USD 85 - USD 75-USD 5). d is incorrect, because it assume all-hours of 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.

Which of the following is an example of basis risk? a. b. c. d.

The The The The

risk of a natural gas price spike during peak electricity demand for a gas fired power generation plant. risk of failure to comply with FERC financial reporting regulations. risk that a megawatt of electricity will cost USD 75 in Pennsylvania and USD 82.50 in New York. risk of the inability of a power generation plant to meet demand in a given market.

Correct answer: c Reading reference: Energy Risk, Pilipovic: Chapter 2, p. 32. Explanation: Answer c is correct. Decentralization introduces geographic “basis risk,” which is unique to energies. In financial markets,today’s dollar is worth a dollar anywhere in the country. In energy markets, price depends on location. A megawatt of electricity is priced according to delivery point; the same holds true for natural gas. Location is a fundamental driver of price. Pilipovic defines “basis risk” as the difference in prices between identical products but in two different markets.

Makati and Sons Heating Oil Company expects customer demand to average 2,200 gallons of heating oil during the 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 Reading reference: Surviving Energy Prices, Beutel, Chapter 3, p. 29-30. 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 Reading reference: Energy Markets: Price Risk Management, James: Chapter 13, p. 263. 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.

Correct answer: a Reading reference: Oil, Gas Exploration, and Production, Institut Francais; Chapter 3, p. 91. Explanation: In 1997 the Society of Petroleum Engineers (SPE) and the World Petroleum Council formulated and adopted standards of reserve definitions. Px is defined as a number such that there is an x% likelihood that the true reserves exceed Px. For example, if the P10 of a field is 100 Mbbl, there is a 10% probability that the actual size of the field exceeds 100 Mbbl. Thus, in this case, P90 indicates a 90% probability the oil field will actually produce more than 50 Mbbl of oil. Other relevant classifications include P95, P50, P10 and P5.

You have a portfolio of gas calls and puts that is gamma neutral. Which of the following trading strategies would you implement to make your portfolio delta neutral? a. b. c. d.

Purchase a call option Purchase a forward contract Purchase either a call or a put option By definition a gamma neutral portfolio is also delta neutral so no action is necessary

Correct answer: b Reading reference: Clewlow and Strickland: Chapter 9.3, p. 170. Explanation: Answer b is correct. Call and put options have delta and gamma values. So the initial portfolio would be constructed with calls and puts such that the gamma of the portfolio was zero. There is no guarantee that the portfolio would also have zero Delta. Since forward contracts are linear, they only have delta and no gamma. Consequently to ensure that a gamma neutral portfolio was also delta neutral, you would buy or sell the right number of forward contracts to make it delta neutral.

Given the following information, how much power capacity (in MWs) would load serving entities in a capacity market be required to purchase to make the building of additional capacity economically viable? Expected end- peak load: Average end- load: Percentage reserve margin: a. b. c. d.

100 MW 90 MW 10%

10 MW 110 MW 100 MW 99 MW

Correct answer: b Reading reference: Making Competition Work in Electricity, Hunt: Chapter 8, p. 166. Explanation: Answer b is correct. Under the capacity obligation system, load serving entities are required to purchase capacity tickets which require them to be able to cover a peak load, plus a reserve. The number of tickets is determined by the formula of peak load, multiplied by (1+x) or the reserve margin percentage. In the scenario above, this gives an answer of 110 MW.

Which of the following tests can be used to demonstrate that model errors are unbiased and normally distributed? I. QQ plot II. R-squared III. Autocorrelation test a. b. c. d.

I and II I and III II and III I, II and III

Correct answer: b Reading reference: Energy Risk, Pilipovic; Chapter 4, p. 81-84. Explanation: QQ plot and the autocorrelation test are used for testing that errors are normally distributed and that there is no bias from error to error. R-squared measure, on the other hand, measures how well the model fits the data. Hence, it tells us nothing about the distribution of the errors, but gives us general information about model performance. Hence, the correct answer is b.

Patel is managing a portfolio with 100 long puts on March peak forward power contracts. If the delta of the put contracts is -0.4, what position in March peak forward power contracts does Patel need to create for the combined portfolio to be delta neutral? a. b. c. d.

Short 40 March Peak Forward contracts Long 40 March Peak Forward contracts Short 60 March Peak Forward contracts Long 60 March Peak Forward contracts

Correct answer: b Reading reference: Energy Derivatives: Pricing and Risk Management, Clewlow and Strickland: Chapter 9.2, p. 164-7. Explanation: Answer b is correct. A Long Put is really a short position in the underlying, in this case March Peak Power. In order to make the delta of the complete portfolio neutral or equal to zero, the position in March Peak Forward power contracts needs to be long an enough to offset the -0.4*100 = -40 of the March Peak Forward. Consequently, one needs to be long 40 March Peak Forward power contracts.

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%. Another call option with the same contract specifications, with a strike 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 tells us that the market is feeling good about the economy and prices are expected to go higher. The different volatilities for the two call options tell us that the lognormal Black model cannot capture the true underlying price behavior with a single volatility measure. A call option with the same contract specifications as the two options in the problem but with a strike of USD 7.00 must therefore be trading at a Black-implied volatility of 55%. The two options should have exactly the same volatility, and therefore this is a case of market arbitrage: the USD 6.00 option is under-priced relative to the USD 6.50 option.

Correct answer: b Reading reference: Energy Risk, Pilipovic: Chapter 8, p. 232. 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. Therefore, the correct answer is b.

Consider global proven recoverable coal reserves. Which of the following correctly lists the countries in order of largest to smallest recoverable coal reserves? a. b. c. d.

United States, China, Russia, Australia, India Russia, United States, India, China, Australia United States, Russia, China, India, Australia China, United States, Australia, Russia, India

Correct answer: c Reading reference: “Producing Liquid Fuels from Coal: Prospects and Policy Issues” Bartis, Chapter 2, p. 5. Explanation: Answer b is correct. As compared to oil and gas resources, coal reserves are often characterized as widely dispersed. On one hand this is an accurate characterization, because major portions of the global reserve base are spread among the continents. On the other hand, the eight nations listed in Table 1.1 hold 88 percent of reported prove recoverable reserves. Leading the list is the United States, with proven recoverable coal reserves of about 270 billion tons.

A call option has a of USD 5 and a strike price of USD 28. What is the time value of the call option if the current price of the underlying is USD 31? a. b. c. d.

USD USD USD USD

5 3 2 0

Correct answer: c Reading reference: Energy Markets: Price Risk Management and Trading, James: Chapter 6, p. 137-8. Explanation: Answer a is incorrect, this is the . b is incorrect, this is the intrinsic value. c is correct. It is the less the intrinsic value: intrinsic value = USD 31 - USD 28 = 3, so USD 5 - USD 3 = USD 2, therefore time value = USD 2. d is incorrect.

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 Reading reference: Energy Derivatives: Pricing and Risk Management, Clewlow and Strickland: Chapter 3.2.2, p. 41. Explanation: Answer a is correct. Volatility has to be estimated in the context of the stochastic process assumption. The volatility for an Ornstein-Uhlenbeck process has different units to that which is used in the 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.
