(a) General rule. A separate line of business is a line of business (as determined under § 1.414(r)-2) that is organized and operated separately from the remainder of the employer. Paragraph (b) of this section sets forth the rules for determining whether a line of business is organized and operated separately from the remainder of the employer. Paragraph (c) of this section provides certain supplementary rules necessary to apply the requirements of paragraph (b) of this section, as well as examples illustrating the application of those requirements. Paragraph (d) of this section provides an optional rule for lines of business that are vertically integrated.

(b) Separate organization and operation—(1) In general. A line of business is organized and operated separately from the remainder of the employer for a testing year only if it satisfies all the requirements of paragraphs (b)(2) through (b)(5) of this section for the testing year.

(2) Separate organizational unit. The line of business must be formally organized as a separate organizational unit or group of separate organizational units within the employer. For this purpose, an organizational unit is a corporation, partnership, division, or other unit having a similar degree of organizational formality. This requirement must be satisfied on every day of the testing year.

(3) Separate financial accountability. The line of business must be a separate profit center or group of separate profit centers within the employer. This requirement must be satisfied on every day of the testing year. In addition, the employer must maintain books and records that provide separate revenue and expense information that is used for internal planning and control with respect to each profit center comprising the line of business.

(4) Separate employee workforce. The line of business must have its own separate employee workforce. A line of business has its own separate workforce only if at least 90 percent of the employees who provide services to the line of business, and who are not substantial-service employees with respect to any other line of business, are substantial-service employees with respect to the line of business. See paragraph (c)(2) of this section to determine how the percentage in the preceding sentence is calculated for the testing year.

(5) Separate management. The line of business must have its own separate management. A line of business has its own separate management only if at least 80 percent of the employees who are top-paid employees with respect to the line of business are substantial-service employees with respect to the line of business. See paragraph (c)(3) of this section to determine how the percentage in the preceding sentence is calculated for the testing year.

(c) Supplementary rules—(1) In general. This paragraph (c) provides certain supplementary rules necessary to apply the requirements of paragraph (b) of this section, as well as examples illustrating the application of those requirements.

(2) Determination of separate employee workforce. The percentage in paragraph (b)(4) of this section is the fraction (expressed as a percentage)—

(i) The numerator of which is the number of substantial-service employees with respect to the line of business within the meaning of § 1.414(r)-11(b)(2); and

(ii) The denominator of which is the total number of employees who provide services to the line of business within the meaning of paragraph (c)(5) of this section and who are not substantial-service employees with respect to any other line of business.

(3) Determination of separate management. The percentage in paragraph (b)(5) of this section is the fraction (expressed as a percentage)—

(i) The numerator of which is the number of employees who are both top-paid employees and substantial-service employees with respect to the line of business within the meaning of § 1.414(r)-11(b)(3) and (2), respectively; and

(ii) The denominator of which is the total number of top-paid employees with respect to the line of business within the meaning of § 1.414(r)-11(b)(3).

(4) Employees taken into account. For purposes of applying this paragraph (c), only employees who are employees on the first testing day are taken into account. For this purpose, there are no excludable employees except nonresident aliens described in section 410(b)(3)(C). Consequently, all other employees who are employees on the first testing day are taken into account, including collectively bargained employees. For the definition of first testing day, see § 1.414(r)-11(b)(7).

(5) Services taken into account—(i) Provision of services to a line of business. An employee provides services to a line of business if more than a negligible portion of the employee's services contributes to providing the property or services provided by the line of business to customers of the employer. All of the services of each employee who provides services to the employer contribute, whether directly or indirectly, to the provision of property or services to customers of the employer, and therefore each employee who provides services to the employer must be treated as providing more than a negligible portion of the employee's services to one or more lines of business operated by the employer.

(ii) Period for which services are provided. Only services performed by an employee during the testing year that contribute to providing the property or services provided by a line of business to customers are taken into account. An employee's services during the testing year are considered to contribute to providing the property or services provided by a line of business to customers of the employer if—

(A) The employee's services during the testing year contribute to providing such property or services to customers of the employer during the testing year; or

(B) It is reasonably anticipated that the employee's services during the testing year will contribute to providing such property and services to customers of the employer after the close of the testing year.

(iii) Optional rule for employees who change status—(A) In general. Solely for purposes of the separateness rules of this section and the assignment rules of § 1.414(r)-7, if an employee changes status as described in paragraph (c)(5)(iii)(B) of this section, an employer may, for up to three consecutive testing years after the base year (within the meaning of paragraph (c)(5)(iii)(B) (1) or (2) of this section), treat the employee as providing the same level of service to its lines of business as the employee provided in the base year.

(B) Change in employee's status. An employee changes status as described in this paragraph (c)(5)(iii)(B) if—

(1) For a testing year (the base year), the employee was a substantial-service employee with respect to a qualified separate line of business of the employer (prior line of business) and, for the immediately succeeding testing year, the employee is not a substantial-service employee with respect to that prior line of business; or

(2) For a testing year (the base year), the employee was a residual shared employee and, for the immediately succeeding testing year, the employee is a substantial-service employee with respect to a qualified separate line of business.

(6) Examples of the separate employee workforce requirement. The following examples illustrate the application of the separate employee workforce requirement in paragraph (b)(4) of this section and the supplementary rules of this paragraph (c). Unless otherwise specified, it is assumed that the employees and their services described in these examples are taken into account under paragraphs (c) (4) and (5) of this section for the testing year and that the employer does not use the option under § 1.414(r)-11(b)(2) to treat employees who provide less than 75 percent of their services to a line of business as substantial-service employees with respect to the line of business.

Example 1.Employer A operates three lines of business as determined under § 1.414(r)-2. One of Employer A's lines of business manufactures and sells tires and other automotive products. Employee M is a tire press operator in Employer A's tire factory. Employee N is the manager of the tire factory. Under these facts, the services of Employees M and N contribute to providing tires to customers of Employer A. Both employees therefore provide services to Employer A's tire and automotive products line of business within the meaning of paragraph (c)(5) of this section. Example 2.The facts are the same as in Example 1. In addition, none of the services of Employees M and N that contribute to providing property or services to customers contribute to providing any property or service other than tires to customers of Employer A. Under these facts, Employees M and N provide at least 75 percent of their respective services to Employer A's tire and automotive products line of business. Therefore Employees M and N are substantial-service employees with respect to Employer A's tire and automotive products line of business within the meaning of § 1.414(r)-11(b)(2), and do not provide any services within the meaning of paragraph (c)(5) of this section to any of Employer A's other lines of business. Moreover, because Employees M and N provide at least 75 percent of their services to Employer A's tire and automotive products line of business and are substantial-service employees with respect to that line, they are disregarded in applying paragraph (b)(4) of this section to any other line of business, even if they provide services to the other line. Example 3.The facts are the same as in Example 2. Employer A's second line of business manufactures and sells construction machinery, and Employer A's third line of business manufactures and sells agricultural equipment. As part of these lines of business, Employer A operates a construction machinery factory and an agricultural equipment factory on the same site as the tire factory described in Example 2. Employer A's facilities at the site include a health clinic and a fitness center that serve the employees of the construction machinery factory, the agricultural equipment factory, and the tire factory. Employee O is a nurse in the health clinic, and Employee P is a fitness instructor in the fitness center. Both employees therefore provide services within the meaning of paragraph (c)(5) of this section to Employer A's tire and automotive products line of business, construction machinery line of business, and agricultural equipment line of business. In addition, under these facts, Employer A determines that approximately 33 percent of the services of Employees O and P are provided to each of Employer A's three lines of business. As a result, neither Employee O or P provide at least 75 percent of their respective services to any of Employer A's lines of business. Therefore, Employees O and P are not substantial-service employees with respect to any of Employer A's three lines of business within the meaning of § 1.414(r)-11(b)(2). Example 4.The facts are the same as in Example 3. Employee Q is the president and chief executive officer of Employer A and is responsible for reviewing the performance of all Employer A's lines of business. Under these facts, the services of Employee Q contributes to providing property and services to customers of each of Employer A's three lines of business. Employee Q therefore provides services to each of these three lines of business. Employer A determines that Employee Q provides the following percentages of his services to Employer A's three lines of business: tire and automotive products—40 percent; construction machinery—40 percent, and agricultural equipment—20 percent. Employee Q does not provide at least 75 percent of his services to any of Employer A's lines of business. Therefore, Employee Q is not a substantial-service employee with respect to any of Employer A's three lines of business within the meaning of § 1.414(r)-11(b)(2). Example 5.The facts are the same as in Example 4, except that Employer A also owns 75 percent of Corporation X. Corporation X is not treated as part of Employer A within the meaning of § 1.410(b)-9. Employee R is an accountant in the accounting department of Employer A. Employee R devotes all of his time to maintaining the accounting books and records of the tire and automotive products line of business of Employer A and the accounting books and records of Corporation X. Employer A determines that Employee R provides 40 percent of his services directly to the tire and automotive products line of business. Employer A also determines that Employee R provides the following percentages of the remainder of Employee R's services (i.e., his provision of services of maintaining the accounting books and records of Corporation X) indirectly to Employer A's three lines of business by virtue of the services he provides to Corporation X: tire and automotive products—25 percent; construction machinery—20 percent, and agricultural equipment—15 percent. Therefore, Employee R provides 65 percent of his services to the tire and automotive products line of business of Employer A (i.e., 40 percent directly and 25 percent indirectly). Under the definition of substantial-service employee in § 1.414(r)-11(b)(2), Employer A may treat Employee R as a substantial-service employee with respect to the tire and automotive products line of business because Employee R provides at least 50 percent of his services to that line. In that case, Employee R would be disregarded in applying paragraph (b)(4) of this section to the construction machinery and agricultural equipment lines of business. Example 6.The facts are the same as in Example 5. Employee S is a lawyer in the legal department located at the headquarters who devotes all her time to product liability suits filed against the construction machinery line of business. Under these facts, the services of Employee S contribute to providing property and services to customers of Employer A in the construction machinery line of business, and therefore Employee S provides services to that line of business. Because Employee S's services do not contribute to providing property or services in any other of Employer A's lines of business within the meaning of paragraph (c)(5) of this section, Employee S provides more than 75 percent of her services to the construction machinery line of business and therefore is a substantial-service employee with respect to Employer A's construction machinery line of business within the meaning of § 1.414(r)-11(b)(2). Example 7.The facts are the same as in Example 6. Employer A also maintains a separate facility that houses a centralized procurement, marketing, and billing operation for all of its lines of business. None of the procurement, marketing, or billing employees specializes in any particular line of business. Under these facts, the services of the procurement, marketing, and billing employees contribute to providing property and services to customers of Employer A in each of Employer A's three lines of business. Employer A determines that each of the procurement, marketing, and billing employees provides approximately an equal proportion of their services to each of Employer A's three lines of business. These employees therefore provide services to all of Employer A's lines of business within the meaning of paragraph (c)(5) of this section. However, none of them provides at least 75 percent of his services to any line of business. Therefore, these employees are not substantial-service employees with respect to any of Employer A's three lines of business within the meaning of § 1.414(r)-11(b)(2). Example 8.The facts are the same as in Example 7. Employee T works for the construction machinery line of business. During the testing year, he is temporarily detailed to the agricultural equipment line of business. His temporary detail lasts for one week, after which he returns to his regular duties with the construction machinery line of business. Under these facts, Employee T does not provide more than a negligible portion of his services during the testing year to the agricultural equipment line of business. Accordingly, Employee T does not provide services to the agricultural equipment line of business within the meaning of paragraph (c)(5) of this section. In addition, because Employee T provides at least 75 percent of his services to the construction machinery line of business, Employee T is a substantial-service employee with respect to Employer A's agricultural equipment line of business within the meaning of § 1.414(r)-11(b)(2). Example 9.The facts are the same as in Example 8, except that, during the testing year but before the first testing day, Employee T retires from employment with Employer A. Under paragraph (c)(5)(ii) of this section, Employee T is not taken into account in determining whether Employer A's construction machinery line of business has its own separate employee workforce within the meaning of paragraph (b)(4) of this section. Example 10.Employer B is a multinational controlled group of corporations that engages in the exploration, production, refining, and marketing of petrochemical products. Employer B operates two lines of business as determined under § 1.414(r)-2. The first line of business (the “exploration, production, and refining line of business”) provides lubricating oil, gasoline, and other petrochemical products to wholesale customers of Employer B as well as to the second line of business. The wholesale customers of Employer B include independent jobbers, independent franchisees that operate retail filling stations under Employer B's trademark and tradename, as well as chemical and plastics manufacturers. The second line of business (the “retail marketing line of business”) provides lubricating oil and gasoline products to retail customers of Employer B through filling stations owned and operated by Employer B. Employee U is an attendant at a filling station owned and operated by Employer B. Employee U performs no other services for Employer B, Under these facts, Employee U provides at least 75 percent of his services to Employer B's retail marketing line of business and therefore is a substantial-service employee with respect to that line of business within the meaning of § 1.414(r)-11(b)(2), and does not provide any services within the meaning of paragraph (c)(5) of this section to any of Employer B's other lines of business. Example 11.The facts are the same as in Example 10. Employer B operates a refinery that produces lubricating oil, gasoline, and other petrochemical products. Employee V is an operating engineer at the refinery who is involved at a stage in the refining process before lubricating oil and gasoline products have been separated from other types of petrochemical products. Employee V performs no other services for Employer B. Under these facts, Employee V's services contribute to providing property and services to customers of Employer B in both the exploration, production, and refining line of business and the retail marketing line of business. Employee V therefore provides services to both lines of business within the meaning of paragraph (c)(5) of this section. See paragraph (d) of this section, however, for an optional rule for vertically integrated lines of business. Example 12.The facts are the same as in Example 11. Employee W is a petroleum engineer who conducts geological studies of potential future drilling sites. Although Employee W's services during the testing year will not contribute to providing lubricating oil, gasoline, and other petrochemical products to customers of Employer B during the testing year, it is reasonably anticipated (in accordance with paragraph (c)(5)(ii)(B) of this section) that her services during the testing year will contribute to providing such products to customers of Employer B after the close of the testing year. Under these facts, Employee W provides her services to both of Employer B's lines of business within the meaning of paragraph (c)(5) of this section.

(7) Examples of the separate management requirement. The following examples illustrate the application of the separate management requirement in paragraph (b)(5) of this section and the supplementary rules of this paragraph (c). Unless otherwise specified, it is assumed that employees who provide services to a line of business are not substantial-service employees with respect to any other line of business and that, in determining the top-paid employees with respect to a line of business, the employer is using the option under § 1.414(r)-11(b)(3) to disregard all employees who provide less than 25 percent of their services to that line of business.

Example 1.(a) Employer C operates three lines of business as determined under § 1.414(r)-2. One of its lines of business is the operation of a chain of athletic equipment and apparel stores. Of Employer C's total workforce, 12,000 employees provide more than a negligible amount of the services they provide to Employer C to the athletic equipment and apparel stores line of business, within the meaning of paragraph (c)(5) of this section. Of the 1,200 employees who constitute the top ten percent by compensation of those 12,000 employees, 930 are substantial-service employees with respect to that line of business. Because 930 is 77.5 percent of 1,200, less than 80 percent of the top-paid employees with respect to the line of business are substantial-service employees with respect to that line of business. Therefore, Employer C's athletic equipment and apparel stores line of business does not have its own separate management under paragraph (b)(5) of this section.

(b) Assume that, in determining the top-paid employees with respect to the athletic equipment and apparel stores line of business, Employer C chooses to disregard all employees who provide less than 25 percent of their services to the line of business as permitted under the definition in § 1.414(r)-11(b)(3). Of the 12,000 employees who provide more than a negligible amount of their services to the athletic equipment and apparel stores line of business, 10,000 provide at least 25 percent of their services to that line. Of the 1,000 employees who constitute the top ten percent by compensation of those 10,000 employees, 930 are substantial-service employees with respect to the athletic equipment and apparel stores line of business. Because 930 is 93 percent of 1,000, at least 80 percent of the top-paid employees with respect to the line of business are substantial-service employees with respect to that line of business. Therefore, Employer C's athletic equipment and apparel stores line of business has its own separate management and satisfies the requirement of paragraph (b)(5) of this section.

Example 2.The facts are the same as in Example 1. Employee X is a vice president of the accounting department located at the headquarters, who devotes all of his time supervising the staff of Employer C's accounting department. Employer C determines that 10 percent of Employee X's services contribute to providing property and services to customers of Employer C's athletic equipment and apparel stores line of business and 45 percent of Employee X's services contribute to providing property and services to customers to each of Employer C's other two lines of business. Because Employee X does not provide at least 25 percent of his services to Employer C's athletic equipment and apparel stores line of business, Employee X is not one of the 10,000 employees described in Example 1 and therefore cannot be a top-paid employee within the meaning of § 1.414(r)-11(b)(3) with respect to the athletic equipment and apparel stores line of business. Therefore, Employee X is not taken into account in determining whether the athletic equipment and apparel stores line of business satisfies the separate management requirement of paragraph (b)(5) of this section. Example 3.The facts are the same as in Example 2 except that Employee X provides 60 percent of his services to Employer C's second line of business, an athletic equipment factory, and 30 percent of his service to Employer C's third line of business, a fast-food chain. Because Employee X provides at least 50 percent of his services to the athletic equipment factory line of business, Employer C chooses to treat him as a substantial- service employee with respect to that line of business, as permitted under § 1.414(r)-11(b)(2). Thus, Employee X is taken into account as a substantial-service employee with respect to the athletic equipment factory line of business and is disregarded in applying the separate workforce and separate management requirements under paragraphs (b) (4) and (5) to the fast-food chain line of business. Example 4.Employer D operates four lines of business as determined under § 1.414(r)-2. One of its lines of business is a machine tool shop. Sixty of Employer D's employees provide at least 25 percent of their services to the machine tool shop line of business. Of the six employees who constitute the top 10 percent by compensation of those 60 employees, four are substantial-service employees with respect to the line of business. Because four is 67 percent of six, 80 percent of the top-paid employees with respect to the machine tool shop line of business are not substantial-service employees with respect to that line of business. Therefore the machine tool shop line of business does not satisfy the separate management requirement of paragraph (b)(5) of this section. Example 5.The facts are the same as in Example 4, except that, in addition, another of Employer D's lines of business is an automotive repair shop, and 80 of Employer D's employees provide at least 25 percent of their services to that line of business. Employer D combines the machine shop line of business with the automotive repair shop line of business and treats them as a single line of business. As a result, Employer D has three lines of business as determined under § 1.414(r)-2. Assume that 150 of Employer D's employees provide more than 25 percent of their services to the machine tool shop/automotive repair shop line of business within the meaning of paragraph (c)(5) of this section. Of the 15 employees who constitute the top 10 percent by compensation of these 150 employees, 12 are substantial-service employees with respect to that line of business. Because 12 is 80 percent of 15, at least 80 percent of the top-paid employees with respect to the machine tool shop/automotive repair shop line of business are substantial-service employees with respect to that line of business. Therefore, the machine tool shop/automotive repair shop line of business satisfies the separate management requirement of paragraph (b)(5) of this section.

(d) Optional rule for vertically integrated lines of business—(1) In general. If two lines of business satisfy the requirements of this paragraph (d) with respect to a type of property or service for a testing year, the employer is permitted to apply the optional rule in this paragraph (d) for the testing year.

(2) Requirements. Two lines of business satisfy the requirements of this paragraph (d) with respect to a type of property or service only if—

(i) One of the lines of business (the upstream line of business) provides a type of property or service to the other line of business (the downstream line of business);

(ii) The downstream line of business either—

(A) Uses, consumes, or substantially modifies the property or service in the course of itself providing property or services to customers of the employer; or

(B) Provides the same property or service to customers of the employer at a different level in the chain of commercial distribution from the upstream line of business (e.g., retail versus wholesale); and

(iii) The upstream line of business either—

(A) Provides the same type of property or service to customers of the employer, and at least 25 percent of the total number of units of the same type of property or service provided by the upstream line of business to all persons (including customers of the employer, the downstream line of business, and all other lines of business of the employer) are provided to customers of the employer by the upstream line of business, when measured on a uniform basis; or

(B) Provides to the downstream line of business property consisting primarily of a type of tangible property (i.e., goods, not services) that it produces or manufactures, and some entities outside the employer's controlled group that are engaged in a similar business as the upstream line of business provide the same type of tangible property to unrelated customers (i.e., customers outside those entities' respective controlled groups).

(3) Optional rule—(i) Treatment of employees. For purposes of determining the lines of business to which an employee provides services under paragraph (c)(5) of this section, an employee is not treated as providing services to the downstream line of business if—

(A) The employee is considered to provide services to the downstream line of business under paragraph (c)(5) of this section (applied without regard to the optional rule in this paragraph (d)); and

(B) The employee is so considered solely because the employee's services contribute to providing the property or service from the upstream line of business to the downstream line of business.

(ii) Purposes for which optional rule applies. If an employee applies the optional rule in this paragraph (d), the treatment specified in paragraphs (d)(3)(i) (A) and (B) of this section applies for all the following purposes and only for the following purposes—

(A) The separate employee workforce and separate management requirements of paragraphs (b)(4) and (b)(5) of this section;

(B) The 50-employee requirement of § 1.414(r)-4(b); and

(C) The determination of the employees of a qualified separate line of business under § 1.414(r)-7.

(4) Examples. The following examples illustrate the application of the optional rule in this paragraph (d).

Example 1.Employer E operates two lines of business as determined under § 1.414(r)-2, one engaged in upholstery textile manufacturing and the other in furniture manufacturing. During the testing year, the upholstery textile line of business provides its entire output of upholstery textiles to the furniture line of business. The furniture line of business uses the upholstery textiles in the manufacture of upholstered furniture for sale to customers of Employer E. The furniture line of business thus substantially modifies the upholstery textiles provided to it by the upholstery textile line of business in providing upholstered furniture products to customers of Employer E. In addition, although the upholstery textile line of business does not provide upholstery textiles to customers of Employer E, some entities engaged in upholstery textile manufacturing provide upholstery textiles to customers outside their controlled groups. Under these facts, Employer E's two lines of business satisfy the requirements of this paragraph (d) with respect to upholstery textiles for the testing year. Example 2.Employer B is a multinational controlled group of corporations that engages in the exploration, production, refining, and marketing of petrochemical products. See Example 10 under paragraph (c)(7) of this section. Employer B operates two lines of business as determined under § 1.414(r)-(2). The first line of business (“the exploration, production, and refining line of business”) provides lubricating oil, gasoline, and other petrochemical products to wholesale customers of Employee B as well as the second line of business. The wholesale customers of Employee B include independent jobbers, independent franchisees that operate retail filling stations under Employee B's trademark and tradename, as well as chemical and plastics manufacturers. The second line of business (the “retail marketing line of business”) provides lubricating oil and gasoline products to retail customers of Employee B through filing stations owned and operated by Employee B. During the testing year, the exploration, production and refining line of business provides 25,000 gallons of lubricating oil, 100,000 gallons of unleaded and 150,000 gallons of leaded gasoline to the retail marketing line of business, and 75,000 gallons of lubricating oil, 500,000 gallons of unleaded gasoline and 15,000 gallons of leaded gasoline to wholesale customers of Employer B. Thus, the exploration, production, and refining line of business provides 75 percent of its output of lubricating oil during the testing year to wholesale customers of Employer B. In addition, because unleaded and leaded gasoline is the same type of property (i.e., gasoline), the exploration, production, and refining line of business provides 67 percent of its output of gasoline products during the testing year to wholesale customers of Employer B. Furthermore, the retail line of business provides lubricating oil and gasoline products to customers of Employer B at different levels in the chain of commercial distribution than the exploration, production, and refining line of business. Under these facts, Employer B's two lines of business satisfy the requirements of this paragraph (d) with respect to both lubricating oil and gasoline products for the testing year. Example 3.The facts are the same as in Example 2. Employer B operates a refinery that produces lubricating oil, gasoline, and other petrochemical products. Employee V is an operating engineer at the refinery who is involved at a stage in the refining process before lubricating oil and gasoline products have been separated from other types of petrochemical products. Employee V performs no other services for Employer B. Absent application of the optional rule in this paragraph (d), Employee V would be considered to provide services to both of Employer B's lines of business. See Example 11 under paragraph (c)(7) of this section. However, because Employee V's services to the retail marketing line of business contribute solely to providing lubricating oil and gasoline products from the exploration, production, and refining line of business to the retail marketing line of business, under the optional rule in paragraph (d)(3)(i) of this section Employee V is not treated as providing services to the retail marketing line of business. Example 4.The facts are the same as in Example 3. Employee W is a petroleum engineer who conducts geological studies of potential future drilling sites. Employee W performs no other services for Employer B. Absent application of the optional rule in this paragraph (d), Employee W would be considered to provide services to both of Employer B's lines of business. See Example 12 under paragraph (c)(7) of this Section. However, because Employee W's services to the retail marketing line of business contribute solely to providing lubricating oil and gasoline products from the exploration, production, and refining line of business to the retail marketing line of business, under the optional rule in paragraph (d)(3)(i) of this section Employee W is not treated as providing services to the retail marketing line of business. Example 5.The facts are the same as in Example 4. Employee Y is a vice president in Employer B's home office. As part of his senior management responsibilities, Employee Y helps to set the rate of production at Employer B's refineries in the United States and also helps to set the price charged at the pump at the retail filling stations owned and operated by Employer B in this country. Absent application of the optional rule in this paragraph (d), Employee X would be considered to provide services to both of Employer B's lines of business within the meaning of paragraph (c)(5) of this section for purposes of satisfying the separate workforce requirement of paragraph (b)(4) of this section. Because Employee X helps to set the price charged at the pump by Employer B's retail marketing line of business, Employee X's services to the retail marketing line of business are not limited to contributing solely to providing lubricating oil and gasoline products from the exploration, production, and refining line of business to the retail marketing line of business, as required under paragraph (d)(3)(i)(B) of this section. Accordingly, even though Employer B's two lines of business satisfy the requirements of this paragraph (d) with respect to both lubricating oil and gasoline products for the testing year, and even though Employer B applies the optional rule in this paragraph (d), Employee X is still considered to provide services to both of Employer B's lines of business. [T.D. 8376, 56 FR 63442, Dec. 4, 1991, as amended by T.D. 8548, 59 FR 32917, June 27, 1994]
