A deterministic variable that converges toward zero as the spot price moves closer to the forward price. A deterministic variable that is highly correlated to the spread between the spot and forward price as the spot price moves closer to the forward price. A stochastic variable that is highly correlated to the spread between the spot and forward price as the spot price moves closer to the long-term equilibrium price. A stochastic variable that converges towards zero as the spot price moves closer to the long-term equilibrium price.

Risk appetite is a willingness to embrace risk, while risk tolerance is an aversion to enduring risk. Risk appetite expresses a range of risk levels an organization is willing to endure, while risk tolerance is a single definitive figure. Risk appetite is a measure of how much risk an organization is willing to take on, while risk tolerance is used to communicate a level of acceptable risk. Risk appetite cannot be derived empirically, while risk tolerance can.

Energy Risk ® Professional(ERP ) Examination Practice Exam 1 Explanations

Energy Risk Professional Examination (ERP®) Practice Exam 1

1.

The market risk manager for a refinery is considering the purchase of a collar for margin protection and uses the following price data for options on NYMEX RBOB futures contracts to assess the economics of the transaction: RBOB Strike Price (USD/bbl) 3.03 3.07

Call Premium (USD)

Put Premium (USD)

0.1461 0.1305

0.1209 0.1407

Assuming the NYMEX RBOB futures contract is trading at USD 3.05, how would the risk manager structure a collar to best manage earnings volatility in the refiner’s operations? a. b. c. d.

Buy put options @ USD 3.03 strike and sell call options @ USD 3.07 strike Sell put options @ USD 3.03 strike and buy call options @ USD 3.07 strike Buy put options @ USD 3.07 strike and sell call options @ USD 3.03 strike Sell put options @ USD 3.07 strike and buy call options @ USD 3.03 strike

Correct answer: a Explanation: The correct answer is a. The collar will help the refiner to hedge price risk and, by extension, margins on its refining operation for the month of October. In this case, the refiner will lock in a range of selling prices between 3.03 and 3.07 (less any cost of implementing the trade). If the RBOB price rallies over 3.07, the sold call will be assigned to the refiner so the refiner will realize an effective price of 3.07. If the price falls below 3.03, the refiner can exercise the put option to lock in the price at that level. Reading reference: Vincent Kaminski, Energy Markets, Chapter 18.

Correct answer: d Explanation: Wrong-way risk arises in cases when the credit risk of the counterparty increases as your exposure to that counterparty increases. In other words, there is a positive correlation between your exposure to a counterparty and the credit risk (or default probability) of that counterparty. Because the counterparty is an oil producer, when oil prices fall and the put option becomes more valuable, the credit risk of the oil producer is increasing. This wrong-way risk is exacerbated by the fact that the put option is out-of-the-money, since it will take a larger decrease in the price of oil, and therefore a greater increase in the oil producer’s credit risk, to make the option in-the-money. In comparison, a shipping company uses oil as an input, so when oil prices decrease (all else being equal), the shipping company is much better off. Therefore, an out of the money put option on oil with a shipping company as a counterparty will generally have right-way risk. Reading reference: Jon Gregory.

Markus Frackus has purchased a daily on-peak call option quote for 100 MW to protect against on-peak electricity price spikes in the PJM market during the month of July. The option has a strike price of USD 100/MWh with a premium of USD 10/MWh per day. Markus forecasts there will be two days when on-peak prices will spike to USD 500/MWh and USD 700/MWh respectively (the on-peak price is usually less than USD 100/MWh). What will be the profit on the option strategy assuming there are 20 business days in the month and 16 on-peak hours per day? a. b. c. d.

USD USD USD USD

320,000 960,000 1,280,000 1,600,000

Correct answer: c Explanation: Answer c is correct, using the following formula: Premium = USD 320,000 or (USD 10 x 100 MW x 16 x 20) Option Payoff = USD 1,600,000 or ((500-100+700-100) x16 x100) Option Profit = USD 1,280,000 or (USD 1,600,000-USD 320,000) Reading reference: IEA, “The Mechanics of the Derivatives Markets: What They Are and How They Function.” (Special Supplement to the Oil Market Report, April 2011).

Central counterparties (CCPs) offer many risk management benefits, but they also have the potential to increase systemic risk. What action taken by a CCP could increase the potential for a systemic risk event? a. b. c. d.

Invoking netting agreements on trades that are in default. Reducing margin requirements on a commodity with low volatility and high liquidity. Conducting an auction to replace positions that are in default. Increasing margin requirements on a commodity with large, highly concentrated positions.

Correct answer: d Explanation: An increase in margin requirements by a CCP could create destabilizing market impacts and therefore add systemic risk. An example of this is a security where large concentrated positions are held. If the CCP were to increase the margin requirement, firms holding these positions might be placed into margin calls which could force them to sell the target security, creating even greater market impact and imposing strains on the funding system and market liquidity.

LNG LNG LNG LNG

exports to fixed-for-floating swaps that allow for future price adjustments. exports to an index based on a basket of Asian crude oils. exports to average long-term bilateral natural gas contracts in the region. export prices to the NYMEX Henry Hub contract.

Correct answer: b Explanation: To improve the ability to hedge and to more accurately reflect market prices, gas contracts have in the past been indexed to a basket of oil prices, making b the correct answer. The other answers are incorrect: answer a is not the proper application of a Fixed-for-Floating swap; long bilateral contracts would not be an accurate source for pricing information; and Henry Hub serves the US domestic market so it too would not be an accurate measure of market forces at play in the Pacific.

Zephyr Energy is evaluating the economics of a pumped hydro storage facility that it will use to store excess power during off-peak hours for distribution later during on-peak periods. Calculate the facility’s projected operating margin using the following historical price data and assuming that the plant’s round trip efficiency is 70% (i.e., 30% of the input fuel is consumed by the storage facility): • •

Average off-peak electricity price for past 5 years: USD 41.20/MWh Average on-peak electricity price for past 5 years: USD 54.50/MWh

a. b. c. d.

USD 11.62/MWh USD 4.09/MWh -USD 4.36/MWh -USD 13.37/MWh

Correct answer: c Explanation: The correct answer is c. Since the plant has a 70% operating efficiency, to determine its operating cost we multiply the off-peak electricity price by 1.4285 (or 1/0.7) to account for the 70% efficiency of the fill cycle (41.20 x 1.4285 = 58.86). USD 58.86 represents the production cost for their electricity, but when this is subtracted from the average on-peak price of USD 54.50, the result is a margin of - USD 4.36. The pumped hydro plant would thus not be profitable.

Using the Quick Ratio as a guideline, which company has the highest relative short-term liquidity risk? a. b. c. d.

Company Company Company Company

A B C D

Correct answer: d Explanation: The Quick Ratio is a more conservative form of the Current Ratio which assumes that a firm will not be able to easily liquidate its inventory, and in a crisis that a firm will not get full market value for its inventory. Hence it is a measure of the liquid assets a firm has available to pay back its current obligations. The formula for the Quick Ratio is as follows: Current assets−Inventory Current Liabilities In this case, Company D has the lowest Quick Ratio, at (72,994 – 45,832) / 48,659, or 0.52. This is because most of Company D’s current assets are held as inventory, which is not easily liquidated. The Quick Ratios for companies A, B and C are 0.86, 1.18, and 4.13 respectively.

Total Liabilities Total Shareholder Equity Long Term Debt Total Current Assets

c.

Long Term Assets Total Current Liabilities

d.

Total Liabilities−Long Term Debt Total Assets

Correct answer: a Explanation: One of the most important debt management ratios is the debt/equity ratio, which assesses the financial leverage of the firm by comparing its level of debt financing to its total net worth. This is expressed as Total liabilities/Total net worth, where total net worth is equal to the firm’s total shareholder equity. Reading reference: Betty Simkins and Russell Simkins, eds.

Coastal Petroleum (CP) operates refineries at strategic locations along the east and west coasts of Canada. After consulting with the finance team, the risk management group implements a strategy to hedge market risk using crack spreads. Use the following NYMEX futures data to price the November RBOB futures contract based on a 3:2:1 crack spread valued at USD 24.30/bbl. • •

November WTI futures price: USD 103.60/bbl November Heating Oil futures price: USD 3.43/gal

a. b. c. d.

USD USD USD USD

1.96/gal 2.85/gal 3.21/gal 3.70/gal

Correct answer: b Explanation: The correct answer is b. A 3:2:1 crack spread is three barrels of crude oil to two barrels of gasoline and one barrel of heating oil. Here the per barrel crack spread of USD 24.30 is given. Multiplying this by three equals USD 72.90. The cost of crude oil is also multiplied by 3 (for the 3 barrels used to calculate the spread): 103.60 x 3 = 310.80, when the refining margin (72.90) is added, the result is 383.70. The price of the heating oil is given as 3.43/gal, multiplying this by 42 (gallons in a barrel) gives an amount of USD 144.06. Subtracting this from USD 383.70 gives a result of USD 239.40, the cost of two barrels of gasoline. Dividing this by 42 (number of gallons in a barrel) and the 2 (the factor for gasoline in a crack spread) gives a per gallon RBOB futures cost of USD 2.85/gal.

should be should be should be and Brent

priced at a discount to the Brent crude oil contract. priced at parity to the Brent crude oil contract. priced at a premium to the Brent crude oil contract. crude have little correlation making the Brent futures contract

Correct answer: a Explanation: Benchmark crudes serve as a pricing standard against which the value of other crude oils can be set. This crude oil would be classified as intermediate crude with a sulfur level slightly higher than Brent, making it likely to sell at a small discount to Brent.

P [Brent Crude Oil price increases more than 2%]: 40% P [Newcastle Coal price increases more than 2%]: 15%

a. b. c. d.

6% 9% 11% 55%

Correct answer: a Explanation: Correct answer is a. The joint probability of two independent events represents the product of the probabilities for each independent outcome. In this case the joint probability is represented by P[B] * P[D] or 6% B is incorrect: 9% = (P[B] + P[D])/P[B] * P[D]) C is incorrect: 11% = (P[B] * P[D])/P[B] + P[D] D in incorrect: 55% = P[B] + P[D] Reading reference: Michael Miller.

A hydroskimming refinery in South America uses the daily Brent crude oil spot price as a benchmark reference for its crude oil feedstock. Assuming the spot Brent price is USD 113.29/bbl, the refinery would most likely purchase which of the following crudes? a. b. c. d.

Canadian Oil Sands (bitumen) at USD 78.06/bbl Mexico Mayan Heavy at USD 101.30/bbl West Texas Sour at USD 114.88/bbl Nigerian Bonny Light at USD 121.87/bbl

Correct answer: d Explanation: The correct answer is d. The refinery is described as a hydroskimming facility making it a “simple” refinery. Therefore it will yield the most gasoline by refining a light, sweet crude, which is choice d, even though Bonny Light is being offered at a premium to Brent (which it typically is). West Texas Sour is a medium weight oil that will require additional processing to remove the sulfur impurities, while the yield from the heavy Mayan crude will seriously reduce the amount of gasoline produced, both of which will negate the discount offered for these crudes. It is unlikely the refinery would even be able to process the raw Canadian bitumen. Reading reference: William L. Leffler. Petroleum Refining in Nontechnical Language, 3rd Edition, Chapter 20.

Why is the time required for physical settlement of energy commodities typically longer than financially settled transactions? a. b. c. d.

Higher SDR reporting requirements Longer re-margining periods Lower liquidity More frequent reconciliations

Correct answer: d Explanation: There are longer settlement times for physically settled commodities because of a greater amount of potential reconciliations. Reconciliation has to wait until the transportation statements come in, and in cases where the actual delivery volume is different than the contracted volume (due to losses during transportation), a “true up” or “actualization” might have to be made. Physical futures typically settle on the 20th or 25th day, while financial derivatives settle on the 5th or 10th day.

What is meant by the term “stranded gas”? a. b. c. d.

A gas deposit that cannot be commercially developed due to an ownership dispute. A gas deposit located in a region with low demand and no access to transport or export facilities. The volume of gas required after extraction to maintain operating pressure at an underground storage facility. The volume of gas related to a default in a take-or-pay contract.

Correct answer: b Explanation: The correct answer is b. Stranded gas is a term used to refer to any deposits of natural gas located in areas of low demand and/or without access to an export facility, such as a pipeline or LNG terminal. The gas is said to be “stranded” since it cannot be brought to market, or no local market exists for it. Since pipelines and LNG terminals are capital intensive, much care must be used in evaluating the economic potential of a “stranded” gas field. Note: choice “c” is the correct definition of “cushion gas”. Reading reference: PriceWaterhouseCoopers. Today’s LNG Market Dynamics.

Wind Speed (m/s)

Correct answer: b Explanation: Correct answer is b. At low levels of wind speed the turbine has not reached its “cut-in” speed so does not produce any power at all. Once it reaches the cut in speed, the energy produced by the turbine increases slowly at first and then more and more quickly. Finally, at a certain wind speed (typically between 11 and 15 meters per second) the turbine reaches 100% of its rated power and continues to operate at that level until it reaches its “cut off point” at very fast wind speeds (typically 25 m/s or higher).

A risk manager at Krakov Airlines is analyzing changes in the EU Emissions Trading Scheme (ETS) program leading up to Phase III of the ETS. What action will Krakov be required to take to comply with the revised terms of the ETS? a. b. c. d.

No changes are required for Krakov to comply with the revised terms of the ETS. Acquire allowances to cover its carbon emissions under the new terms of the ETS. Install fuel-efficient engines in all its planes to comply with the new terms of the ETS. Acquire LULUCF credits to comply with the new terms of the ETS.

Correct answer: b Explanation: As part of the changes leading up to the implementation of Phase III of the EU ETS, the aviation industry was included for the first time in the ETS in 2012, the last year of Phase II. Therefore Krakov should acquire carbon allowances to cover its carbon emissions. LULUCF (land use, land-use change and forestry) credits are not acceptable to cover allowance requirements in the EU ETS program.

How can Key Performance Indicators (KPIs) and Key Risk Indicators (KRIs) be applied to best achieve an organization’s risk management objectives? a. b. c. d.

Use KPIs exclusively to develop an effective forward looking assessment of trends in operational risk factors. Integrate KPI objectives and KRI limits to create a single comprehensive risk-weighted metric. Monitor KRIs to assess shifts in risk exposure and adjust business strategy and operational procedures to better meet return on risk objectives identified by KPIs. Replace KPIs with KRIs and adjust company-wide risk capital allocations to account for the change in risk monitoring procedures.

Correct answer: c Explanation: The correct answer is c. One problem with the use of KPIs for risk management is that they are backward-looking: they will only show how well the portfolio has met pre-determined goals. KRIs are an ongoing process of monitoring the portfolio performance to ensure that it stays within pre-determined risk measurements. Using them together as described in answer c is an effective risk-management strategy. Adjustments to the portfolio can be made in accordance to the KRIs that can ultimately help the portfolio reach the KPIs.

Consider a European country that relies on the following mix of power generation sources to meet its domestic electricity requirements: • • • • •

Wind - 35% Gas - 30% Coal - 10% Nuclear - 20% Hydro - 5%

The national energy policy dictates that the country will actively expand its wind generation capacity. What best describes the economics of wind generation as it accounts for a larger portion of the country’s total domestic capacity? a. b. c. d.

High marginal costs and higher incremental balancing costs High marginal costs and lower incremental balancing costs Low marginal costs and higher incremental balancing costs Low marginal costs and lower incremental balancing costs

Correct answer: c Explanation: The correct answer is c. Wind power has very low marginal cost given its high capital intensity and enters the merit order curve at a low level. However, given the intermittency of wind power production this will lead to higher balancing costs as more wind power enters the system.

a. b. c. d.

71,000 79,000 107,000 187,000

Correct answer: b Explanation: The correct answer is b. The 99% VaR will use a confidence factor of 2.33 while the 95% VaR will use a confidence factor of 1.64. Therefore the 99% VaR is: 118.55 * 50 contracts * 0.0192 * 1000 barrels / contract * 2.33 = 265,172, while the 95% VaR is: 118.55 * 50 * 0.0192 * 1000 * 1.64 = 186,645. Hence the difference is 78,500. . Reading reference: Allan Malz, Financial Risk Management: Models, History, and Institutions (Hoboken, NJ: John Wiley and Sons, 2011), Chapter 3.

Calculate the spark spread for a combined cycle natural gas turbine plant based on the following assumptions: • • •

Average plant heat rate: 8,500 Btu/kWh Current price of natural gas: USD 5.00/MMBtu Current price of electricity: USD 30.00/MWh

a. b. c. d.

USD USD USD USD

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

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.

What best describes the drift term in a single-factor, mean reverting model? a. b. c. d.

A deterministic variable that converges toward zero as the spot price moves closer to the forward price. A deterministic variable that is highly correlated to the spread between the spot and forward price as the spot price moves closer to the forward price. A stochastic variable that is highly correlated to the spread between the spot and forward price as the spot price moves closer to the long-term equilibrium price. A stochastic variable that converges towards zero as the spot price moves closer to the long-term equilibrium price.

Correct answer: d Explanation: The correct answer is d. In a single factor model the drift term is stochastic. As St approaches L, the drift term approaches zero and the time it takes for St to reach L tends to infinity (alternatively, St approaches L asymptotically).

What best explains the differentiation between risk appetite and risk tolerance? a. b. c. d.

Risk appetite is a willingness to embrace risk, while risk tolerance is an aversion to enduring risk. Risk appetite expresses a range of risk levels an organization is willing to endure, while risk tolerance is a single definitive figure. Risk appetite is a measure of how much risk an organization is willing to take on, while risk tolerance is used to communicate a level of acceptable risk. Risk appetite cannot be derived empirically, while risk tolerance can.

Correct answer: c Explanation: The correct answer is c; this is the correct definition of risk appetite and risk tolerance.

A credit risk analyst notices that data is missing from the following credit report: Bond Name Exposure Recovery rate Loss given default Expected loss

Koryo Energy ? 27% USD 4,506,700 USD 3,372,800

What is the original exposure on the Koryo Energy bond position? a. b. c. d.

USD USD USD USD

4,620,270 6,173,500 12,491,800 16,691,500

Correct answer: b Explanation: The correct answer is b. Since Loss Given Default = Exposure * (1-recovery rate), then the exposure is equal to the LGD divided by (1-recovery rate). Therefore the original exposure on the position is 4,506,700 / (1-0.27) or approximately USD 6,173,500. Reading reference: Allan Malz.
