Glossary of Terms and Usage

The Glossary of Terms and Usage provides guidelines for proper word usage and style. Entries not followed by text merely indicate the correct U.S. spelling of the given term.

This glossary is organized into five segments. The General Terms section provides usage standards embraced by many journalists and other global communications professionals. Of course, some terminology is particular to Dana Incorporated, and the Dana-Specific Terms section provides related usage standards. Finally, this glossary contains terminology specific to the accounting, information technology, and legal disciplines.

General Terms

academic degrees
Academic degrees should only be used when necessary to establish a person’s credentials. When possible, avoid abbreviating degrees by integrating the degree into the sentence. The formal “Bachelor of Arts” is capitalized, whereas “bachelor’s degree” is lowercase. See also bachelor’s degree and master’s degree.

Abbreviate terms such as “Ave.” “Blvd.” and “St.” only with a numbered address: 1600 Reynard St. Spell these words out when used without a number: Reynard Street. These three terms are the only ones that can be abbreviated. Related terms such as “alley,” “drive,” “road” and “terrace” must always be spelled out. Always use numerical figures for an address number: 9 Foxlair Drive. Spell out and capitalize First through Ninth when referring to a street name. Dana’s Corporate Headquarters is located at 3939 Technology Drive.

affect, effect
Generally, “affect” is the verb. The interest-rate hike affected the stock price. “Effect” is the noun. The rate hike had a significant effect. Effect, as a verb, means to cause or bring about. He was the type of manager who could effect change.

Always use numerals. The policy was 20 years old. When preceding a noun, hyphenate. The 20-year-old policy was a good one.

all right
There is no such word as “alright.”

a.m., p.m.
Always lowercase with periods. There is a space between the numeral preceding a.m. or p.m. and the abbreviation. The office closed at 5 p.m.

annual, biannual, biennial, semiannual
Annual is every year. Don’t use “first” with it (if it’s the first time, it can’t be annual). Biannual and semiannual mean twice a year. Biennial means every two years.



bachelor’s degree

because, since
“Because” is used to denote a cause-and-effect relationship. He did it because he was told to do so. “Since” denotes a timeframe. He hadn’t eaten since 11:30 a.m.

brand names
Always capitalize. Be careful to note that many common terms are actually brand names, e.g., Band-Aid®, Kleenex®, Xerox®, etc. All Dana brands and sub-brands should be used as an adjective modifying a noun, e.g., Spicer® axle, Victor Reinz® gasket, etc. Dana is the company and Spicer is the brand. Do not refer to a brand as Dana Spicer, it should be Dana’s brand, Spicer.

capital, capitol
“Capital” typically refers to the city in which a seat of government is located. “Capitol” refers to a building. “Capitol” is capitalized when used in conjunction with the building in Washington, D.C., or a specific state capitol building, e.g., U.S. Capitol, Capitol Square, but “capital” is not generally capitalized.


For amounts less than a dollar, use numerals. He had only 5 cents in his pocket. For amounts greater than a dollar, use a dollar sign and decimals. The lunch cost $6.25.

cents per share
Rules from “cents” entry above apply. Exceptions are made in tabular formats, such as earnings releases and annual reports.

collective nouns
If the collective noun is considered a group, the verb and pronoun are singular. Dana has a tradition of valuing its people. If the collective noun is considered as individuals acting on their own, the verb and pronoun are plural. Dana people have been actively involved in their communities. Note: This entry is U.S. specific.

complement, compliment
“Complement” is synonymous with the word “supplement.”
“Compliment” refers to an expression of appreciation.

compose, comprise
“Compose” means to put together. Operations in more than 25 nations compose Dana’s international resources. To “comprise” is to include. Dana comprises several core businesses.

couple of
The preposition “of” is required. It’s never, “a couple axles.”

Always use arabic numerals. The big meeting was set for January 14. When expressing the year, dates should be set off by commas. Jan. 14, 1993, was a cold day. When no date appears, commas are not necessary. January 1993 was a cold month.

Use arabic numerals and spell out words such as “inches,” “feet,” “yards,” etc.

Use figures for units of 10 and above; spell out lesser units. Due to fatigue, he walked eight miles of the 26-mile run. Be conscientious of international material. Use metric conversions with parentheses as appropriate.

Use the arabic figure in conjunction with a dollar sign, unless referring to amounts without a specific figure or in very casual references. He wore $500 shoes, but refused to loan her a couple of dollars for lunch.

Use lowercase “e” with a hyphen to designate “electronic”, unless it is at beginning of sentence. E-commerce is an important topic. He led the e-business initiative. Download our e-book.

e.g., i.e.
These abbreviations are commonly confused. The abbreviation “e.g.” means “for example,” while “i.e.” means “in essence” or “that is.”

Acceptable for electronic mail. Do not use “email” as a verb.

engine, motor
These terms are not synonymous. An engine produces power, while a motor receives power.

ensure, insure
To ensure something is to guarantee it. To insure something is to cover it with insurance.

farther, further
“Farther” refers to distance. After being re-routed by the airline, she was farther from her destination than when she began. “Further” indicates that something is more distant in degree, time, or space. Nothing could be further from the truth.

fewer, less
If you can quantify the items being compared, use “fewer.” If not, use “less.” Michigan had fewer fans at the game than Ohio State. The Buckeyes had less experience than the Wolverines.

in, into
“In” refers to location. Jim was in his office. “Into” refers to motion. Jane walked into Jim’s office.

Generally abbreviated and capitalized when used as part of a formal corporate name. Mack Trucks, Inc., is a member of the Volvo Group. Defer to the guidelines of the legal entity. The formal name of the company is Dana Incorporated; however, referring to Dana Incorporated as simply “Dana” is acceptable and encouraged when used in a non-legal manner. References to “Dana Holding Corporation” should be discontinued. Dana Incorporated on first reference should always be spelled out. Review Dana Brand Standards Company Name.

it’s, its
“Its” is possessive. Dana values its people. “It’s” is the contraction for “it is” or “it has.”

job titles
Capitalize formal titles appearing prior to a name. Plant Manager John Smith delivered the keynote address. Lowercase such titles after the name. John Smith, plant manager of the Townsville facility, met with his team.

Never judgement.

lay, lie
To “lie” is to recline. To “lay” is to cause to recline or to place.

like, as
In general, use “like” to compare nouns and pronouns. She looked like a beauty queen. Use “as” when comparing to phrases or clauses that contain a verb. Ted walked as if his pants were on fire. “Like” and “such as” are also frequently misused. Dana makes products such as driveshafts and gaskets.

master’s degree
Master’s degree in Business Administration is preferred to MBA. Do not capitalize. Dana’s chairman earned his master’s degree from the Wharton School of the University of Pennsylvania.

mean, median
The “mean” designates the middle point between two extremes. It is not synonymous with an average, which is arrived at by totaling a series and dividing the sum by the number of items in the series. The “median” is the middle number of points in a series arranged in order of size.

In reference to communication outlets (newspapers, television, and radio stations, etc.), as well as forms of communication, the word is plural. The media are relentless in the pursuit of news.

miles per gallon
The abbreviation mpg (no periods) is acceptable on second reference.

miles per hour
The abbreviation mph (no periods) is acceptable in all references.

nationalities and races
In general, usage should be avoided, but if necessary, capitalize proper names, e.g., African American, French Canadian, etc.

Spell out numerals that begin a sentence. Spell out numerals between zero and nine. Use numerals to express values of 10 and above. Use numerals in percentages at all times.

In general, spell out first through ninth, and use figures for 10th and above. An exception to this rule is the use of figures when part of a formal name. He was proud to represent the 1st Ward.

over, more than
“Over” refers to a position. The jet flew over the mountain. “More than” refers to an amount. He had more than $10 in his wallet.

percent and percentage
One word. Spell out in text, use % in headlines and tables.

Use light truck when possible.

The following prepositions should appear in lowercase when used in headlines, even those employing initial caps (unless the preposition is the first word):


principal, principle
“Principal” means first, highest, or foremost in importance. “Principle” refers to a basic truth or standard.

publication names
Italicize the names of magazines, newspapers, and books. Enclose the titles of articles, speeches, etc., in quotations.

Use arabic numerals and hyphens. Dana outperformed its competitors by a ratio of 2-to-1.

registered marks
Use superscript TM, SM, or ® as appropriate in first reference. Spicer® driveshafts are well-known and respected. If you have questions regarding whether a term is a registered trademark, contact the Dana Law Department’s Intellectual Property Department.

state names
Spell out the names of U.S. states when they stand alone in text. Abbreviate, when appearing with a city name, as referred to in the next section.

state abbreviations
Most state names may be abbreviated in conjunction with the name of a city, county, town, or village. Eight states are never abbreviated. These are: Alaska, Hawaii, Idaho, Iowa, Maine, Ohio, Texas, and Utah. Also: District of Columbia

While Postal Service abbreviations are preferred when addressing letters or packages, they are not appropriate in other written materials. Associated Press state abbreviations are preferred and should appear as follows:


that, which
Use “that” to introduce restrictive clauses. The Dana product that shows the most profit potential will likely be the subject of great interest. Use “which” to introduce non-restrictive clauses (those that explain further). The Dana plant, which is producing 1,000 components a day, was established in 1988.

Tier I, Tier II, etc.

Use arabic numerals except for noon and midnight (not 12:00 a.m. or 12:00 p.m.). He was scheduled to attend the meeting from noon to 2:30 p.m. Do not use “00” for times at the top of the hour, e.g., 6 p.m.

Not “towards.”

Use trademarks as adjectives, not nouns. Note the first usage of a trademarked item within a document with the appropriate trademark symbol (also note first usage within headlines and captions if applicable). To learn more about Dana trademarks, please visit

The word “unique” indicates that something has no like or equal. Therefore, there are not degrees of uniqueness, and claims of uniqueness often do not correspond to the definition. As such, the word should be used with careful consideration.

United States
Spell out when used as a noun. Abbreviate (U.S.) only when used as an adjective.

Abbreviate as “vs.” in all uses. The words, “compared to” are preferred in most cases.

Washington, D.C.

Use arabic numerals. The baby weighed 7 pounds, 6 ounces.

who, whom
Generally, use “who” to refer to someone who has been the actor, and “whom” to refer to someone who has been the object of an action. He was a 20-year Dana veteran who had never missed a day of work. The plant manager, to whom the job was new, enjoyed the challenge.



Use arabic numerals without commas. 1964. Use an “s” without an apostrophe to indicate decades. The 1960s. When abbreviating a decade, an apostrophe should point back toward the missing numerals. Some believe the ’80s were a period of great excess.

ZIP code
ZIP is the acronym for Zoning Improvement Plan and should thus appear in all caps.

Dana-Specific Terms

Every company has its own terminology, as well as its own guidelines for usage with regard to selected industry terms. The following are several Dana-specific terms and related usage guidelines.

business units
Dana’s four market-focused global business units are the Light Vehicle Driveline Technologies, Commercial Vehicle Driveline Technologies, Power Technologies, Off-Highway Drive and Motion Technologies.

Dana defines a system as a set of components, interfaces, or software that works together to perform a key function of a vehicle. One or more of a vehicle’s modules may be contained in a system.

Webphonet is Dana’s web-based phone and facility search engine.

Accounting and Financial Terms

Numbers are vital to accurately expressing Dana’s performance both internally and to outside constituencies. The following are several key accounting and financial terms and measures used by Dana.

Cash and other physical items or rights that can be converted to cash or consumed in the production of goods and services.

balance sheet
A listing of assets, liabilities, and the resulting net worth of an organization.

basic earnings per share (EPS)
Net income divided by the weighted average number of basic common shares outstanding during the period.

basis point
One one-hundredth (0.01) of one percent. Basis points are typically used to express yield differences among fixed income securities.

bond ratings
Grades assigned by credit-rating agencies to corporate and municipal debt securities, based on the borrower’s expected ability to repay. Credit-rating firms assign grades to borrowers. Standard & Poor’s, for example, has 10 grades, ranging from its top grade, “AAA,” downward to “D,” signifying a security that is in payment default.

capital spend
The cost of property, plant, and equipment, with a useful life of more than one year, purchased during the period.

The reduction in the value of capital goods due to wear, age, and/or obsolescence.

diluted earnings per share
Net income (adjusted) divided by the weighted average number of basic common shares plus potentially dilutive shares outstanding during the period.

Earnings Before Interest, Taxes, Depreciation, and Amortization (EBITDA) is an approximate measure of a company’s operating cash flow based on data from the company’s income statement. Calculated by looking at earnings before the deduction of interest expenses, taxes, depreciation, and amortization. This earnings measure is of particular interest in cases where companies have large amounts of fixed assets which are subject to heavy depreciation charges (such as manufacturing companies). Since the income tax and financing effects on company earnings do not factor into EBITDA, it is a good way of comparing companies within and across industries.

effective tax rate
Effective tax rate is determined by dividing tax expense by income before income taxes in a given period. For example, if a taxpayer recorded tax expense of $25,000 on income before income taxes of $100,000, the effective tax rate would be 25 percent. The effective tax rate is a useful tool in tax planning and provides a quick measure of the effectiveness of a company’s tax strategy.

equity investments
Equity investments are generally those investments in other companies or entities in which we hold a 20 to 50 percent ownership interest. The accounting for these investments – the equity method – generally consists of a single line on the balance sheet and a single line in the income statement representing the proportionate share of the net assets and net income of the investee, respectively.

The euro is the official monetary unit of 19 member nations of the European Union, which includes Austria, Belgium, Cyprus, Estonia, Finland, France, Germany, Greece, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Portugal, Slovenia, Slovakia, and Spain.

net income
Net profit, or earnings.

net book value
The carrying value of an asset, reduced by valuation allowances or accumulated depreciation or amortization.

price-earnings ratio
The price of a share of stock divided by earnings per share for a 12-month period.

return on invested capital (ROIC)
Annualized profit after tax, plus the after-tax amount of interest, divided by total equity plus short- and long-term debt.

return on sales (ROS)
Financial return on sales (ROS) is calculated by dividing net income by net sales.

The revenue a company receives for the goods and services it sells.

Grammar and Punctuation

The Dana Communications Style Guide is not intended to serve as a grammar and punctuation primer. Instead, this section offers basic information regarding a few of the most common grammar and punctuation issues confronted by communicators. For items not addressed herein, please defer to the Associated Press Stylebook.

Always use the word “and” instead of an ampersand symbol (&).

To form a possessive with most words, simply add an apostrophe and the letter “s” to the end of the word. In words ending with “s” or “x,” simply add an apostrophe to the end of the word. Charles Dickens’ novels include many classics. When dealing with a pair of items, only the second one requires an apostrophe to form a possessive. John and Jane’s mother was recovering nicely from her illness. With regard to the pronoun “it,” the possessive case of the pronoun “it” is “its.” The word “it’s” is the contraction for “it is” or “it has.”

bulleted lists
For bulleted lists, a period should be used only if the information is presented as a complete sentence. If the information is not in the form of a complete sentence, no period is needed. To be consistent throughout the document, use the same format in a single document to avoid confusion.

A colon can be used after a grammatically complete lead-in sentence that announces a subsequent enumeration, explanation, illustration, or extended quotation. The markets Dana serves are as follows: automotive, commercial vehicle, and off-highway.

In addition to the basic rules regarding comma usage (which can be found in virtually any grammar textbook), please note that Dana’s Corporate Communications Department employs what is more commonly known as the serial comma (comma between the final two items in a series). Dana is focused on the automotive, commercial vehicle, and off-highway markets.

Dashes should be used to interrupt the flow of a sentence. There should be a space on both sides of the dash. The customer was happy – nearly giddy, in fact – about the new product.

ellipsis periods
Ellipsis periods indicate that a word or words have been eliminated from a passage. They should be treated like a three-letter word, preceded and followed by a space, except at the end of a sentence, where four periods are used consecutively. Abraham Lincoln said, “We here highly resolve that these dead shall not have died in vain … and that government of the people, by the people, for the people, shall not perish from the earth.”

Hyphens are used to connect words that form a compound adjective, which modifies another word.  There should not be a space on either side of a hyphen. Many of Dana’s products address the growing light-truck marketplace.

quotation marks and punctuation
Generally, when using quotation marks, periods and commas should be placed inside the quote mark, while colons and semi-colons should be placed outside. Placement for both question marks and exclamation points is dependent on the situation.

A semicolon is used to join two independent clauses. Dana people contribute hundreds of thousands of ideas annually; they are known for their innovations. Additionally, semicolons can be used to convey greater separation than a comma, but less than a period. For example, they may be employed to distinguish between items in a list containing multiple commas. Dana’s Off-Highway group has European facilities in Brugge, Belgium; Györ, Hungary; and Arco, Montano Lucino, and Rovereto, Italy.

spacing before and after /
When using a “/” in a sentence, there should be a space placed between each word and the “/”. Let me know if you have any questions / comments.

using www. in front of websites
It is not necessary to use “www.” at the beginning of a URL. Use camel-case capitalization for the URL, e.g.

Dana-Specific Guidelines

In most style matters, Corporate Communications defers to the Associated Press Stylebook, the industry standard for journalists and communication professionals. Of course, some style matters are not an issue of “right or wrong,” but instead involve choices. In these cases, our goal is consistency in usage. The following are several style choices employed and endorsed by Corporate Communications:

genderless language
Genderless language is the standard in today’s business environment. When using genderless language, use plurals or specific descriptions to avoid words such as he, she, and it.

Gender biased: The operator examines the part. He then sends it to the finishing area.

Genderless: The operator examines the part and then sends it to the finishing area.

honorifics (Mr., Ms., Miss, and Mrs.)
Dana news releases employ the honorifics “Mr.” and “Ms.” on second and subsequent references. Do not use “Miss” or “Mrs.,” unless the individual wishes to be specified as such.

two spaces after period
Periods ending a sentence should be followed by two spaces prior to the beginning of the next sentence. An exception to this rule occurs when writing copy specifically for the websites, social media, advertising and collateral. In which case there is only one space between the period and the beginning of the next sentence.

Product Glossary

A beam supporting a vehicle on which one or more wheels turn. Axles also house and support the differential, shafts, and wheels that propel the vehicle. Axles can be “driving,” conveying power to turn the wheels, or “dead,” merely supporting the vehicle’s weight and allowing the wheels to turn. Axles are designed to suit a variety of suspension systems. Beam axles are traditional, but many vehicles now utilize axle assemblies for independent suspension systems.

Automotive Acronyms

Avoiding “Alphabet Soup”
Acronyms are commonplace in automotive industry communications. While occasionally necessary to avoid lengthy or repetitive sentences, acronyms are best avoided when possible.

Plural and possessive Forms
To form the plural form of an acronym, simply add the letter “s” (there is no need for an apostrophe). Several OEMs took part in the trade show. To form the possessive form of an acronym, employ an apostrophe and the letter “s.”

The following is a brief list defining a number of automotive acronyms.
