On Wednesday, Aug. 28, the National Energy Board (NEB) became the Canada Energy Regulator (CER). For further information please visit our Implementing the Canadian Energy Regulator Act information page
Pipeline Tolls and Tariffs: A Compendium of Terms
The following provides a general explanation of the terms and expressions commonly used in the course of hearings under Part IV of the National Energy Board Act concerning tolls and tariff matters and in Reasons for Decision documents. The objective is to promote a better understanding of the National Energy Board's proceedings by the public. Accordingly, certain explanations have been deliberately simplified. They neither replace nor interpret terms defined in the Act or regulations.
Terms Are Listed Alphabetically
Allowance for Funds Used During Construction (AFUDC)
The cost of funds used during the period of construction when a utility undertakes to construct its own facilities. The amount of the allowance is included in the total capitalized cost of the asset and is depreciated over the life of the asset after it is placed in service. AFUDC is similar to "Interest During Construction" for unregulated industries except that in determining AFUDC, the cost of equity capital is normally taken into account.
A systematic writing-off of an amount over a period of time.
After-Tax Weighted-Average Cost of Capital. The after-tax weighted average of the required returns for each source of capital (i.e. common equity, debt, preferred equity).
A method for determining the appropriate return, based on the premise that the overall return should be the key element in determining a fair rate of return and should be comparable to the overall after-tax return of other companies of similar risk.
Average Service Life (ASL) Depreciation
A group method of depreciation whereby the rate of annual depreciation is based on the average service life or average remaining service life of the group. This rate is applied to the surviving balances of the asset group's costs.
A "paper transport" of natural gas by displacement against the flow on a single pipeline so that the natural gas is notionally delivered upstream of the point at which it enters the system.
Base Year or Base Period
A historical period (usually 12 consecutive months), for which actual data is available. It is used as the starting point in determining tolls for the future test year. (See Test Year)
One-hundredth of a percentage point. It is used in reference to interest rates or rates of return on equity.
Beta or Beta Factor
A measure of the systematic risk of a security. It estimates the extent to which a stock's price fluctuates more or less than the market portfolio. A stock with a beta greater than one fluctuates more than the market average and is therefore considered to be of higher risk and may generate a higher return than the market average.
Calculated values used in toll design to allocate a pipeline company's revenue requirement between tollpayers. Billing determinants generally account for both volume and distance.
A debt security issued by a borrower that obligates the issuer to make specified payments to the holder over an established period.
A quality rating assigned by credit rating agencies as an indication of creditworthiness.
The amount at which an item appears in the books of account and financial statements.
The risk attributed to the nature of a particular business activity (as distinct from financial risk). For pipelines, it typically includes supply, market, regulatory, competitive and operating risks.
The total funds invested in a company by lenders (debt capital) and by owners (equity capital).
Capital Asset Pricing Model (CAPM)
A method used to estimate the cost of equity capital by comparing the return and risk characteristics of an individual company's shares to the average for all shares in the market. (See Comparable Earnings Test, Discounted Cash Flow Test and Equity Risk Premium)
Capital Attraction Standard
One of the Fair Return standards which requires that the return of a regulated utility permit incremental capital to be attracted to the enterprise on reasonable terms and conditions. (See Comparable Investment Standard, Fair Return Standard and Financial Integrity Standard)
Capital Cost Allowance (CCA)
An income tax deduction allowed for certain fixed assets used in operating a business. CCA is similar in nature to depreciation used for accounting purposes; however, the rates allowed are prescribed by income tax regulations and are not intended to reflect an asset's useful service life.
The way in which a business is financed. It is generally expressed as a percentage breakdown of the types of capital employed. For example, a utility could have a capital structure of 50% debt, 15% preferred shares and 35% common equity.
Capital structure expressed in dollar amounts.
Capitalized Overhead or Cost of Overhead During Construction
The amount of a company's overhead expenditures allocated to the cost of acquisition or construction of an asset. The total cost of the asset, including capitalized overhead and AFUDC, is depreciated over the asset's life.
Cash Working Capital
The amount of cash needed to allow for the time lag between the payment of ongoing operating expenses and the collection of corresponding revenues. (See Lead-Lag Study and Working Capital).
A charge applied only to quantities actually transported. Under a Straight Fixed Variable Toll Design it includes only the variable costs of a pipeline. (See Demand Charge and Straight Fixed Variable Toll Design)
A pipeline company that is obligated to ship all product offered to it for transmission, without contract and usually by monthly nominations. In the event that capacity is not available to meet all requests, services are prorated amongst users. (See Contract Carrier)
The book value of a company's common shares outstanding including retained earnings or net of accumulated deficits.
Common Equity Ratio
The ratio of the common equity to the total capital of a company.

A method used to estimate the cost of equity capital by comparing the returns earned by companies with similar investment risk to that of the regulated utility's operations. (See Capital Asset Pricing Model, Discounted Cash Flow Model, and Equity Risk Premium)
Comparable Investment Standard
One of the Fair Return standards which requires that the return of a regulated utility be comparable to the return available from the application of the invested capital to other enterprises of like risk. (See Capital Attraction Standard, Fair Return Standard and Financial Integrity Standard)
The business risk that results from competition for customers at both the supply and market ends of a pipeline system.
An audit undertaken to determine whether a company is complying with legal or contractual provisions relating to its accounts, or with rules, regulations, and prescribed procedures. In the case of a company regulated by the Board, a compliance audit would primarily include the examination of the company's accounts to ascertain whether the company is complying with the Uniform Accounting Regulations and any orders issued by the Board.
A pipeline company that provides transportation for remuneration to customers who have contracted for the service over a specific period. (See Common Carrier)
Quantity of natural gas specified in a firm service agreement that a pipeline is obligated to be able to deliver on any day at a delivery point or delivery area.
Cost of Preferred Equity Capital
The effective yield on a company's preferred shares.
Cost of Service
The total cost of providing service, including operating and maintenance expenses, depreciation, amortization, taxes, and return on rate base. Generally, the cost of service of a pipeline is the same as its revenue requirement. (See Revenue Requirement)

Daily Contract Quantity (DCQ)
The maximum amount of energy per day that a customer can move under its transportation contract with a pipeline.
A long-term corporate debt obligation that is not secured by any specific asset of the company, but rather is based on the company's general creditworthiness.
Deemed Capital Structure
A notional capital structure used for toll-making purposes that may differ from a company's actual capital structure.
For regulatory purposes, generally, a type of account used to record revenues and expenses held in abeyance for future disposition by a regulator.
Deferred Income Taxes
The amount by which income taxes determined on the basis of accounting income exceeds income taxes payable. In a utility, this amount results primarily when capital cost allowance used in calculating taxable income is larger than corresponding depreciation used in calculating accounting income. Deferred income taxes are carried on the balance sheet of a company as a non-current liability. (See Normalized Income Taxes, Flow-through Income Taxes, and Capital Cost Allowance)
A geographic area within a toll zone that is comprised of multiple delivery points where shippers receive delivery of their natural gas.
The point specified in a service agreement where a pipeline delivers gas to or for the account of a shipper.

Embedded Cost of Debt
The weighted-average historical cost of long-term debt outstanding.
The total of preferred and common equity. (See Common Equity and Preferred Equity)
Equity Risk Premium of Common Shares
The spread reflecting the difference in risk associated with holding common equity as opposed to debt or preferred shares. The cost of common equity capital is usually greater than the cost of debt or preferred shares.
Equity Risk Premium (ERP) Model
Family of methods used for estimating the cost of common equity which includes the Capital Asset Pricing Model. It is based on the premise that an investment in common equity carries greater risk than an investment in either debt or preferred shares and, therefore, requires a higher return, or premium, over that required for bonds or preferred shares. (See Capital Asset Pricing Model, Comparable Earnings Test and Discounted Cash Flow Test)
A retirement of a depreciable asset that results from circumstances not foreseen when determining the asset's service life for depreciation purposes.
Fair Return Standard

FFO Interest Coverage
Funds from Operations (FFO) over gross interest incurred before subtracting capitalized interest and interest income. (See Funds from Operationsand Interest Coverage Ratio)
FFO to Total Debt Ratio
Funds from Operations (FFO) over long-term debt (including amount for operating lease debt equivalent) plus current maturities, commercial paper and other short-term borrowings.
Financial Integrity Standard
One of the Fair Return standards that requires that the return of a regulated utility enable the financial integrity of the regulated enterprise to be maintained. (See Capital Attraction Standard, Comparable Investment Standard and Fair Return Standard)
The proportion of debt in relation to equity in a utility's capital structure. The higher the long-term debt, the greater the financial leverage. Shareholders benefit from financial leverage to the extent that return on the borrowed money exceeds the interest costs and that shares rise in market value. Leverage also means required interest and principal payments and thus, ultimately, the risk of default (higher financial risk).
The risk inherent in a company's capital structure. Financial risk increases as the proportion of debt increases in relation to shareholders' equity.
Firm Transportation (FT) Service
A firm (non-interruptible) gas transportation service which provides for the delivery of gas up to a specific maximum daily quantity. The shipper must pay a monthly demand charge regardless of the quantities transported and a commodity charge for the quantities actually transported. (See Demand Charge and Commodity Charge)

Costs that remain, at least in the short run, relatively constant and do not vary with throughput. Examples are interest expense, depreciation charges, and property taxes. (See Variable Costs)
A toll which does not vary with changes in throughput or expense variances. Fixed tolls are usually based on forecasts of costs and throughput for a test year. (See Variable Cost-of-Service Toll)
Flow-Through Income Tax Methodology
A method of estimating income taxes payable for a period based on taxable income as opposed to accounting income.
An audit restricted to a particular management function or operation. (See Management Audit)
Full-time Equivalent (FTE)
The equivalent of one full-time employee position in terms of the number of hours worked during a year. An FTE can be made up of allocations from different employee positions.
Funds From Operations (FFO)
Net income from continuing operations plus depreciation, amortization, deferred income taxes and non-cash items, and interest expense. (See FFO Interest Coverage)
The original cost of fixed assets before deducting accumulated depreciation. (See Net Plant)
Group 1 Company
In general, Group 1 companies are those with more extensive systems and as such are subject to a greater degree of regulatory oversight than Group 2 companies.
Group 2 Company
Group 2 companies tend to be smaller, have fewer shippers and are subject to a lighter degree of regulatory oversight since they are regulated on a complaints basis.
Alternatives or modification to cost of service regulation where a utility's profit is at least partly dependent on efficiency gains.
Tolls resulting from a toll design methodology that assigns capital and operating costs of new facilities to their own cost pool, separate from the costs of the existing facilities. Tolls are designed so existing shippers pay a toll reflecting the cost of service associated with existing facilities; "new" shippers pay a toll reflecting the cost of service associated with new facilities.
Incremental Transportation Cost
The variable cost of transporting an additional unit of throughput. (See Fixed Costs and Variable Costs)
Interest Coverage Ratio
The number of times that net income for a given year, before interest expense and income taxes, covers the annual interest expense. This ratio is one measure of the creditworthiness of a company.
Inequity occurring when a generation of customers does not pay, at the expense of another generation, its fair share of the costs incurred by the utility in providing service.
Interim Toll Order
An order authorizing a company to charge specified tolls until a final order is made. At the discretion of the Board, revised tolls may be made applicable from the date the interim tolls became effective. In such case, any difference between the final and interim tolls during that interim period are refunded to, or recovered from, shippers.
Regulatory approval of tolls resulting from arm's length negotiations, rather than calculated on a cost of service basis, and subject to challenge only under a complaint proceeding.

A toll design similar to Straight Fixed Variable with the exception that certain fixed costs, for example return on equity and associated income taxes, are shifted from the demand toll to the commodity toll. (See Straight Fixed Variable Toll Design)
Negative Salvage Value
The amount by which the cost of removing an asset from service exceeds the salvage proceeds.
An agreement between a pipeline company and interested persons concerning issues related to the company's revenue requirement, tolls, tariffs, and operational matters. In discussions leading to such an agreement, interested persons have a fair opportunity to participate and have their interests recognized and appropriately reflected. In situations where the parties are able to settle all outstanding issues and the Board is satisfied that there are no public interest considerations that extend beyond the immediate concerns of the negotiating parties and that the settlement results in just and reasonable tolls and does not contradict the National Energy Board Act, the need for a formal hearing process before the Board would normally be eliminated.
The effective price to the producer of natural gas, based on the downstream market price less any charges for delivering the gas to market.
Gross plant less associated accumulated depreciation. (See Gross Plant or Plant in Service)
Proceeds from the disposition of an asset or from the issue of securities after deducting the related expenses.
A precise listing of the quantities of energy to be transported under a contract during a specified time period which a shipper provides to the pipeline.
Normalized Income Taxes
An estimate of income taxes based on accounting income. The estimate may vary from the income taxes payable because certain revenues and expenses are recognized for account at different times than they are for tax purposes. (See Deferred Income Taxes, Flow-through Income Taxes, and Capital Cost Allowance)

ROE Formula or RH-2-94 Formula
Formula to establish the rate of return on common equity for certain NEB-regulated pipelines, established in the RH-2-94 Proceeding, as amended to eliminate rounding.
Tolls resulting from a toll design methodology in which the capital and operating costs of new facilities are added to those of the existing facilities; i.e. there is one cost pool for all facilities. Tolls are designed to recover the annual cost of providing service. All shippers who receive the same service pay the same toll. Tolls only vary according to such factors as volumes and distance.
The money that must be regularly set aside according to the terms of a long-term debt or preferred share issue, in order to redeem part of the issue prior to or at maturity.
Tolls that would be paid by only those shippers utilizing specific facilities or assets that are physically distinguishable from the existing facilities. They would be based on a revenue requirement independent of that calculated for the rest of the system. (See Incremental Tolls and Rolled-in Tolls)
Straight Fixed Variable (SFV) Toll Design
A toll design whereby all fixed costs are assigned to the demand toll and all variable costs are assigned to the commodity toll. (See Modified Fixed Variable Toll Design)
The risk that the physical availability of supply could affect a pipeline's income-earning capability.

The price charged by a pipeline company for transportation and other services.
Ratemaking techniques used to defer costs traditionally recovered through tolls in the early years of a pipeline's life, to later years in order to level out tolls over time. Can also refer to the shifting of tolls within a shorter time period, for example, to gradually phase in a significant toll increase. (See Intergenerational Inequity)
Tolls Task Force
A joint industry task force initiated by certain pipeline companies. It is generally comprised of representatives of the pipeline company and, potentially, a wide cross-section of the industry including representatives of the producing, marketing, brokering, provincial governments, local distribution, and industrial end-user sectors with an interest in the services provided on that pipeline. The objective is to foster lines of direct communication, possibly leading to negotiated settlements of some issues outside the Board's adjudicative process.

Costs that vary with throughput, such as compressor fuel costs for gas pipelines and power costs for oil pipelines. (See Fixed Costs)
Variable Cost-of-Service Toll
A toll which varies from month to month to reflect actual costs and throughput. Rules prescribed by the regulator specify which costs can be recovered, the accounting principles to be followed in determining the costs, the rate of return allowed on the investment in rate base, depreciation rates, and other parameters. (See Fixed Toll)
For regulatory purposes, capital employed by the utility to finance its ongoing operations, in addition to the investment in Plant in Service.
