      1
      The Honorable Michael J. Davis, United States District Judge for the District
of Minnesota, sitting by designation.
       The district court2 entered summary judgment partially in favor of North Dakota
State University and partially in favor of the United States in this Federal Insurance
Contributions Act (FICA) tax case involving North Dakota State University's early
retirement program. The district court determined that payments to tenured faculty
under the program were not wages within the FICA definition of wages but that
payments to high-level administrators under the program were wages subject to FICA
taxation. The United States appeals the decision regarding the tenured faculty and
North Dakota State University cross-appeals the decision regarding the administrators,
to the extent it applies to those administrators who North Dakota State University
asserts also had tenure rights. We affirm.3

                                           I.

      The material facts are generally undisputed in this case disposed of on cross
motions for summary judgment. North Dakota State University (hereinafter "NDSU")
offered an Early Retirement Program to tenured faculty and to certain high-level
administrators whose age and years of service totaled 70 (or 65 during some periods
of time). Participation in the program was voluntary by both parties–neither the
employee nor NDSU could force the other to enter into an Early Retirement
Agreement. Once they agreed to enter into an Early Retirement Agreement, NDSU and
the employee negotiated the payment amount. The payment was capped at 100% of
the employee's most recent annual salary, but the prospective retiree was not
automatically entitled to the full amount. Various factors were considered in setting the

      North Dakota State University also sought refunds for FICA taxes based on
wages paid to teachers and trainees who were residents of other countries and were
working at the university on J-1 work Visas. The district court denied the refund.
North Dakota State University does not challenge that ruling on appeal.
                                           2
retirement payment, including past performance, current salary, curriculum needs, and
budget restraints. These were not the only factors considered during the negotiations;
in fact, there was no restriction on the factors that could be considered. Under the
Early Retirement Agreement, the employee agreed to give up any tenure, contract,
and/or other employment rights, agreed not to seek employment with a North Dakota
public university or college, and agreed to give up any claim against NDSU under the
Age Discrimination in Employment Act.

       The Early Retirement Program was available to faculty who had received tenure.
Tenure was granted to a faculty member upon recommendation by NDSU to the North
Dakota Board of Higher Education (the Board), which made the final tenure decision.
NDSU had a tenure track of six years, during which time faculty members were
evaluated annually. The six-year track was not set in stone, however, and occasionally
tenure was granted earlier, even upon hire. Under NDSU and Board policy, the six-
year probationary period could be waived for faculty having tenure at another university
or having a record of outstanding achievement. The Board considered various factors
in making tenure decisions, including scholarship in teaching, contribution to a
discipline or profession through research, other scholarly or professional activities, and
service to the institution and society.

       Tenure was not a right that could be demanded by a professor. Once tenure was
granted, however, tenure gave the professor the right to continuous academic year
employment in the specific program area for which the tenure was granted. The annual
tenure contracts were automatically renewed each year unless termination was
permitted under the policies. Under the terms of the tenure program, which were non-
negotiable, a tenured faculty member could be terminated based upon various fiscal
reasons, including a demonstrably bona fide financial exigency, loss of legislative
appropriations, loss of institutional or program enrollment, consolidation of academic
units or program areas, or elimination of courses. Additionally, tenured faculty could
be terminated for adequate cause, which was defined as demonstrated incompetence

                                            3
or dishonesty in teaching, research, or other professional activities; continued or
repeated unsatisfactory performance evaluations; substantial and manifest neglect of
duty; conduct which substantially impaired fulfillment of responsibilities; physical or
mental inabilities to perform duties; and continued violations of NDSU or Board
policies. Absent fiscal constraints or adequate cause, a tenured faculty member could
not be terminated. The tenure policies required that specific due process rights and
procedures be afforded a tenured faculty before any termination.

       Certain high-level administrators were also eligible to participate in the Early
Retirement Program, including "the president, vice presidents, deans and officers of the
institution who [we]re members of TIAA/CREF, TFFR and TIRF." (NDSU policy §
360, Appellant's App. at 14.) These administrators had certain employment rights
pursuant to NDSU and Board policy, including a right to extended notice before
dismissal, depending on the administrator's length of employment. Three months notice
was required during the administrator's first year, six months during the second year,
and twelve months notice thereafter. Upon compliance with the early notice
provisions, the administrators could be terminated without cause. (NDSU policy § 183,
Appellant's App. at 69-70).

      Prior to 1991, NDSU withheld the employee's portion of FICA taxes from Early
Retirement Program payments and paid its employer's share of FICA taxes. During
1991, some Early Retirement Program participants questioned NDSU's payroll
department about the applicability of FICA taxes to the payments. Both NDSU's
payroll director and general counsel researched the issue by reviewing privately
published tax law treatises and attempting to contact the Internal Revenue Service
(IRS) and the Social Security Administration (SSA).4 NDSU posed a question to the


      4
       The United States claims that NDSU never contacted the IRS. NDSU claims
its general counsel talked to someone in the local IRS office and was directed to the
SSA. Whether NDSU in fact contacted the IRS is immaterial to disposition of these
                                           4
SSA concerning whether NDSU's "Tenure Buy-Out Program," under which "an
employee is offered a sum of money to sell their Tenure back to the University," is
considered wages for FICA purposes. (Appellant's App. at 83.) The SSA responded
in a letter stating that, as described by NDSU, the program was "in effect, a payment
to secure the release of an unexpired contract of employment," and as such, under the
Social Security Procedure Operations Manuals, was not considered wages for purposes
of determining benefit amounts or for deduction of benefits purposes. (Id.) Based on
the SSA letter, and without seeking further outside advice or a private letter ruling from
the IRS, NDSU stopped both withholding and paying FICA taxes on the Early
Retirement Program payments.

       The IRS audited NDSU on June 22, 1995, and assessed deficiencies in FICA
taxes for the years 1991 through 1994 with respect to the Early Retirement Program
payments. NDSU paid the assessment and thereafter began withholding and paying
FICA taxes on the early retirement payments. NDSU later filed for a refund of the
FICA taxes for the periods of 1991 through 1997. Upon denial of the refund claim,
NDSU filed this suit.

        The district court determined that the payments to the administrators were wages
subject to FICA taxation because the administrators were at-will employees, subject
only to the extended notice provisions. Because the payments were based on factors
traditionally used to determine compensation, the district court found that the payments
were wages for FICA purposes. The district court treated the tenured faculty members
differently, however, because the faculty had a recognized property interest in their
tenure. The district court concluded that the payments to tenured faculty were made
in exchange for the relinquishment of a property or contract interest rather than for
compensation and as such were not subject to FICA taxation. The United States
appeals the ruling regarding the tenured faculty. Counsel for NDSU clarified at oral


cases.

argument that NDSU is appealing the ruling only to the extent that payments made to
administrators who NDSU alleges also had tenure rights were deemed wages for FICA
purposes. NDSU concedes that nontenured administrators were at-will employees and
subject to FICA taxation. We affirm.

                                          II.

       We review summary judgment dismissals de novo, applying the same standard
as the district court. See Melvin v. Yale Indus. Prods., Inc., 197 F.3d 944, 946-47 (8th
Cir. 1999). Tax assessments made by the IRS are presumed correct and the taxpayer
bears the burden of proving, by a preponderance of the evidence, that the assessment
is erroneous. See Boles Trucking, Inc. v. United States, 77 F.3d 236, 239 (8th Cir.
1996). The crux of this case is whether payments made to tenured faculty, in exchange
for which the tenured faculty gave up their tenure rights, are subject to FICA taxes as
defined by the Internal Revenue Code. This is, we believe, an issue of first impression
in the federal circuit courts.5

      The Internal Revenue Code imposes FICA taxes on "wages" received by an
employee "with respect to employment." Internal Revenue Code (I.R.C.) § 3101, 26
U.S.C. § 3101. The employer is required to withhold FICA taxes from the employee's
wages and is required to pay an equal amount itself as an employment tax. See I.R.C.
§§ 3102, 3111. The term "wages" is defined for FICA purposes as "all remuneration
for employment" with enumerated exceptions, none of which apply to this case. I.R.C.
§ 3121(a). "Employment" is defined as "any service, of whatever nature, performed
by an employee for the person employing him." I.R.C. § 3121(b). These terms "are
worded so as to 'import breadth of coverage,'" Mayberry v. United States, 151 F.3d

      5
       Indeed, the only federal district court case to address the issue of FICA taxes
on payments to tenured faculty for release of their tenure rights as far as we are aware
is an unpublished decision from the Southern District of Texas. See Slotta v. Texas
A&M Univ. Sys., 1994 US Dist LEXIS 21205 (S.D. Tex. Aug. 10, 1994).
                                           6
855, 860 (8th Cir. 1998) (quoting Soc. Sec. Bd. v. Nierotko, 327 U.S. 358, 365
(1946)), to further the policies behind the Social Security Act as originally codified in
1935. See Nierotko, 327 U.S. at 364-66 (holding that "any service . . . performed"
includes the whole employer-employee relationship and is not limited to only
productive activity).

       Although wages and employment are read broadly in the FICA context, clearly
not all payments by employers to employees constitute wages. "Wages usually are
income, but many items qualify as income and yet clearly are not wages." Cent. Ill.
Pub. Serv. Co. v. United States, 435 U.S. 21, 25 (1978). The payments must be
remuneration for services provided by the employee to his employer to be subject to
FICA taxes.

       Three closely related principles emerge from our review of the tax law relevant
to this dispute. In Revenue Ruling 58-301,6 an employee entered a five-year
employment contract. See Rev. Rul. 58-301, 1958-1 C.B. 23.7 The employer and the
employee agreed to cancel the contract in the second year. The employer paid the
employee a lump sum in exchange for the employee's relinquishment of his contract


      6
        "Although revenue rulings do not have the force of law, they are entitled to
respectful consideration, and are to be given weight as expressing the studied view of
the agency whose duty it is to carry out the statute." United States v. Howard, 855
F.2d 832, 836 (11th Cir. 1988) (internal quotations and citations omitted); see also
McMartin Indus., Inc. v. Vinal, 441 F.2d 1274, 1276 (8th Cir. 1971). Because there
is no case law directly on point, we find revenue rulings especially useful in analyzing
the issue before us.
      7
       Despite the government's argument that Revenue Ruling 58-301 is of
questionable authority, it concedes that the IRS has not withdrawn or otherwise
overruled it and continues to follow it. See Gen. Couns. Mem. 38,098 (Sept. 19,
1979), 1979 WL 52981(confirming the IRS's continued approval of Rev. Rul. 58-301).


                                           7
rights. The IRS determined that the lump sum payment was not FICA wages, or
remuneration for employment, but consideration for relinquishing rights under the
contract, i.e., the right to be employed for the full five years. Thus, in the view of the
IRS, payments to relinquish rights under a contract are not wages for FICA purposes.
See also Slotta, 1994 U.S. Dist. Lexis 21205, at *4-5 (holding that payment to a
professor for relinquishing tenure rights was not wages for FICA purposes). Cf.
Abrahamsen v. United States, 228 F.3d 1360, 1365 (Fed. Cir. 2000) (rejecting
argument that exit incentive payments to at-will employees were in exchange for
agreement to release all claims against employer where there was no evidence that
employees ever asserted claims against the employer), cert. denied, 121 S. Ct. 1484
(2001); Associated Elec. Coop., Inc. v. United States, 226 F.3d 1322, 1328 (Fed. Cir.
2000) (rejecting argument that early-out payments made to mine workers were in
exchange for agreement not to strike where payments were offered to all employees,
including nonunion employees).

       In Revenue Ruling 74-252 the IRS determined that payments made to an
employee after his employer terminated his three-year employment contract were FICA
wages. See Rev. Rul. 74-252, 1974-1 C.B. 287. The contract provided that the
employer could terminate the employee during the term of the contract as long as it paid
the employee an additional six months salary, which it did. The IRS distinguished
Revenue Ruling 58-301 by characterizing it as payment for “the relinquishment of
interests the employee had in his employment contract in the nature of property.”
Conversely, the case before the IRS in Revenue Ruling 74-252 involved payments
made under the contract. Thus, in the IRS's view, payments made pursuant to an
employment contract are wages for FICA purposes. See also Greenwald v. United
States, 2000 WL 16939, at *4 (S.D.N.Y. Jan. 10, 2000) (holding that a lump-sum
payment which essentially paid the employee for anticipated earnings pursuant to an
employment agreement were FICA wages).




                                            8
       In Revenue Ruling 75-44, a railroad employee received a lump-sum payment in
exchange for relinquishing seniority rights gained from his prior service under a general
contract of employment. See Rev. Rul. 75-44, 1975-1 C.B. 15. The employee was an
at-will employee who had acquired the rights to security in his employment and to
additional pay or other recognition based on longevity; however, the railroad had no
obligation to maintain the relationship. The railroad paid the employee a lump sum to
transfer to a different position and to forego his seniority rights. The IRS determined
that the lump sum payment constituted remuneration for services for purposes of the
Railroad Retirement Tax Act (RRTA), the equivalent of FICA for railroad employees,
because the rights given up were those earned by past service–or seniority. The
payment was similar to a severance package, which rewarded an employee for past
service. Thus, according to the IRS, payments for past services, or seniority rights, are
wages for FICA purposes. See also Abrahamsen, 228 F.3d at 1364 ("If the payments
at issue were merely severance payments that were not conditioned on a release of any
claims, they would constitute 'wages' because they would be compensation paid to the
employees by their employer for the employer-employee relationship.").

       Thus, we must determine whether the payments made under NDSU's Early
Retirement Program to tenured faculty in exchange for release of the faculty's tenure
rights are payments to relinquish contractual or property rights, payments pursuant to
a contractual agreement, payments for past services, or something else.

                                 A. Tenured Professors

      The parties agree that tenure is a protected property right. In this circuit, a
tenured professor at a state institution not only has a constitutional right to procedural
due process, but also has "a substantive due process right to be free from discharge for
reasons that are 'arbitrary and capricious,' or in other words, for reasons that are trivial,
unrelated to the education process, or wholly unsupported by a basis in fact." Morris
v. Clifford, 903 F.2d 574, 577 (8th Cir. 1990) (refusing to grant qualified immunity to

                                             9
university personnel for discharging a tenured professor at the University of North
Dakota because a tenured professor's right to substantive due process was clearly
established); see also Mueller v. Regents of the Univ. of Minn., 855 F.2d 555, 559-60
(8th Cir. 1988) (requiring substantial evidence to support the university's decision to
terminate a tenured professor protected by substantive due process). NDSU policy also
provided that tenured faculty could not be terminated absent fiscal restraints or
adequate cause. Thus, the faculty who gave up their tenure rights at NDSU in
exchange for early retirement gave up the right not only to invoke proper procedure
before tenure was lost, but a right not to lose tenure at all without justification.

       Despite the fact that tenure at a state institution is a constitutionally protected
property interest and that the tenured faculty had clear contractual rights not to be
terminated absent specific circumstances, the government argues that tenure rights are
not contract rights that can be relinquished because the tenure rights have no economic
value that can be bought and sold. We are unpersuaded by this argument. Rarely
would we expect to find an employment contract that would have recognizable
economic value to anyone other than the employee.8 Lack of a market in which to sell
tenure rights does not prevent those rights from having value to the faculty member to
whom tenure has been granted. Cf. Vail v. Bd. of Educ. of Paris Union Sch. Dist. No.
95, 706 F.2d 1435, 1451 (7th Cir. 1983) (Posner, J., dissenting) ("A contract that gives
a teacher the right to be employed till he retires is special, for unless he is old or rich
the present value of his tenure right is probably his biggest asset."), aff'd, 466 U.S. 813
(1984).

       The government next argues that tenure rights accrue over time, similar to
seniority, making this case analogous to Revenue Ruling 75-44. Although past service


      8
       Indeed, counsel for the United States agreed at oral argument that the
employment contract at issue in Revenue Ruling 58-301, payment for which the IRS
found not to be subject to FICA taxes, could not be bought and sold.
                                            10
plays a part in the decision to grant tenure, tenure is much more than a recognition for
past services. Importantly, tenure is not automatic upon completing service for a
specified time period, which is a hallmark of ordinary seniority rights. Prior to an
award of tenure, a professor is employed pursuant to one-year contracts for a period
of time, generally six years at NDSU. The six years during which a professor teaches
before being granted tenure is not consideration for the grant of tenure. Rather, it is
ordinarily a prerequisite for tenure and serves as a probationary period during which
the university may evaluate the professor to determine whether he or she has the
qualities necessary to be worthy of tenure. After serving the probationary period, the
professor must still qualify for tenure through his or her scholarship, research, and
service to the university and society. "The decision to award tenure rests on criteria
that reflect the potential long-term contribution of the faculty member to the purposes,
priorities, and resources of the institution, unit, and program." (NDSU policy § 352,
Appellant's App. at 74.) At the end of the probationary period, the professor's contract
is either not renewed and the professor discontinues teaching at the university, or the
professor is granted tenure and a lifetime appointment, as long as the grounds for
removal are not triggered. See generally Mayberry v. Dees, 663 F.2d 502, 514-16 (4th
Cir. 1981) (discussing the tenure process in-depth, including the value of the
probationary period as an evaluation tool), cert. denied, 459 U.S. 830 (1982).

       A tenured professor, therefore, experiences two successive relationships with the
university: the initial at-will relationship during the probationary period and the
subsequent tenured relationship. They are two distinct relationships. The tenured
position is "a significantly different status–effectively a new job." Mayberry, 663 F.2d
at 516 (discussing the distinct differences between the relationship a professor has with
the university during the probationary period and following the grant of tenure).

       Thus, contrary to the government's argument that tenure rights are earned by past
service to the university, tenure rights are established at the outset of the tenured
relationship. Tenure is a recognition of contributions to the academic world and is given

                                           11
in exchange for continuing contributions. Under NDSU and Board policy, tenure also
serves the purpose of protecting academic freedom. It provides a secure forum for the
germination, cultivation, and exchange of ideas without fear that expression of
viewpoints will result in retribution. It is this unique relationship and its accompanying
rights, formed only when and if tenure is granted, that give tenure its significance and
value. Because we reject the government's underlying premise that tenure accrues over
time and is similar to seniority, we reject its argument that Revenue Ruling 75-44
should control the outcome of this case.

       The government also argues that the retirement payments are FICA wages
because the amount of the payments was based in part on the employee's past
performance and current salary. Although we have previously relied on the method
used to calculate a payment to determine whether it is subject to FICA taxation,
particularly when the payment is measured by factors traditionally associated with
compensation, those cases involved at-will employees. See Mayberry, 151 F.3d at 860
(holding that payments in class action settlement of an ERISA claim to at-will
employees were FICA wages where each class member's award was based on the
member's length of service with the employer); The Lane Processing Trust v. United
States, 25 F.3d 662, 665-66 (8th Cir. 1994) (holding that payments to employees, from
a trust set up by their employer with the agreement that the trust funds would be
distributed to employees who agreed to stay on at reduced wages, were FICA wages
where the funds were allocated between the employees based on length of service and
position with the company). The tenured faculty in the case at hand clearly were not
at-will employees. They were protected by a contractual relationship with NDSU and
by constitutional principles of procedural and substantive due process. Additionally,
past performance and current salary were not the only factors considered in determining
the amount of the early retirement payments; in fact, there was no limit on what factors
could be considered. Thus, although the method used to calculate a payment is relevant
to whether the payment is wages for FICA purposes, it is not dispositive, see
Associated Elec., 226 F.3d at 1328, and we do not deem the inclusion of past

                                           12
performance and current salary as some of the factors in the decisional mix here to be
controlling in this case.

        We also find the government's reliance on cases involving dismissal payments
unavailing. Treasury regulations provide that “[a]ny payments made by an employer
to an employee on account of dismissal, that is, involuntary separation from the service
of the employer, constitute wages, regardless of whether the employer is legally bound”
to make the payments. Treas. Reg. § 31.3401(a)-1(b)(4). See also Rev. Rul. 74-252,
1974-1 C.B. 287 (defining dismissal payments for FICA purposes the same as defined
for withholding purposes in Treas. Reg. § 31.3401(a)-1(b)(4)). The terminations
involved here were totally voluntary by both parties; it is uncontroverted that neither
NDSU nor a tenured faculty member could enter an Early Retirement Program
agreement unless the other party freely consented. This case clearly does not involve
dismissal payments.

      Under the terms of the Early Retirement Program, the tenured faculty received
a negotiated amount of money in exchange for giving up their constitutional and
contractual rights to tenure. In other words, they relinquished their tenure rights. They
did not receive what they were entitled to under their contracts, which was continued
employment absent fiscal constraints or adequate cause for termination. Rather they
gave up those rights, making this case more analogous to Revenue Ruling 58-301 than
to Revenue Ruling 74-252.9 We hold that payments made to tenured faculty under


      9
        This point distinguishes the faculty at issue in this case from the administrators
who were entitled only to extended notice. Although we do not reach the issue of
whether administrators who did not have any tenure rights were subject to FICA taxes
because NDSU does not raise it on appeal, we were troubled by the fact that the
negotiations with faculty were apparently not different from those conducted with
administrators. However, the administrators were entitled to, at most, twelve months
notice before termination. The faculty were entitled not to be terminated at all, unless
certain circumstances were met.

NDSU's Early Retirement Program were made in exchange for the relinquishment of
their contractual and constitutionally-protected tenure rights rather than as remuneration
for services to NDSU. Thus, the payments are not subject to FICA taxation.

                                   B. Administrators

       NDSU contends that some administrators had tenure and should be treated the
same as the tenured faculty. The only evidence offered to support this factual
allegation are bald assertions made in depositions. Although affidavit or deposition
testimony is sufficient to create a fact issue for summary judgment purposes, NDSU
has never offered any documentary evidence of the administrators’ tenure rights.
"When written documents are relied on, they must be exhibited in full. The statement
of the substance of written instruments or of affiant's interpretation of them . . . are not
sufficient." Sprague v. Vogt, 150 F.2d 795, 800 (8th Cir. 1945). Statements in
deposition testimony that the administrators were protected by tenure rights via
contracts and/or policies are insufficient, without evidence of the contract or policy, to
establish those rights as a fact. See Washington Post Co. v. Keogh, 365 F.2d 965, 971
(D.C. Cir. 1966) (affirming grant of summary judgment where documentary evidence
relied on in affidavits was not produced), cert. denied, 385 U.S. 1011 (1967). As such,
NDSU has failed to raise an issue of fact for this summary judgment proceeding. See
Fed. R. Civ. P. 56(e) (“Sworn or certified copies of all papers or parts thereof referred
to in an affidavit shall be attached thereto or served therewith.”); Carmen v. San
Francisco Unified Sch. Dist., 237 F.3d 1026, 1028 n.4 (9th Cir. 2001) (noting that Rule
56(e) requirements for affidavit testimony apply equally to deposition testimony).

      Evidence to the contrary reveals that the administrators, who were non-classified
employees according to NDSU's brief (Appellee's Br. at 5) and subject to policy § 183
according to its deposition testimony (Thorsen Dep. at 30-32, Suppl. App. at 32), could
be terminated without cause pursuant to the requisite extended notice period. (NDSU
policy § 183(1), Appellant's App. at 69.) Tenure was limited to the academic unit or

                                            14
program area for which it was granted and did not extend to administrative positions.
(NDSU policy § 350.1(1)(c), Appellant's App. at 56.) "Tenured appointments
recognize a right . . . to continuous academic year employment in an academic unit or
program area . . .." (NDSU policy § 350.1(4)(b), Appellant's App. at 58.) NDSU has
failed to establish that the administrators who were not on the academic staff were
anything other than at-will employees entitled only to extended notice before
termination. On this record, the administrators are not entitled to be treated the same
as the tenured faculty.

                          C. Deputy Tax Collector Defense

        Finally, NDSU argues that to the extent any of the payments are subject to FICA
tax, it is protected by the "deputy tax collector" defense, which protects an employer
from liability for failing to withhold employment taxes from its employees when the
employer lacks "precise and not speculative" notice of its duty to withhold. See Cent.
Ill., 435 U.S. at 31 (noting that "the employer is in a secondary position as to liability
for any tax of the employee"). The defense applies only to that portion of the FICA tax
required to be withheld from the employee; it does not apply to the employer's primary
obligation to pay its portion of the FICA tax. See, e.g., H B & R, Inc. v. United States,
229 F.3d 688, 692 (8th Cir. 2000) (reversing district court's judgment against the
employer for taxes required to be withheld from the employee's wages, but not for
FICA taxes the employer was required to pay, based on Central Illinois).

       The district court found that payments to the administrators were subject to
FICA taxation because the administrators were at-will employees and the payments
were based on factors traditionally associated with compensation. (See Dist. Ct. Order,
Add. at 10-12). NDSU does not appeal this decision, other than to argue that some of
the administrators were additionally protected by tenure rights and thus should be
treated similarly to the tenured professors rather than the other at-will administrators.
Because we have rejected this argument as lacking any factual basis in the record, we

                                           15
treat all of the administrators as at-will employees subject to extended notice rights, as
did the district court.

       NDSU withheld FICA taxes from all payments under the Early Retirement
Program prior to 1991, when some participants questioned the practice. As discussed
previously, FICA withholding is required for all wages paid to employees, and is
broadly construed. The Supreme Court established in 1946 that the term "wages"
includes the whole employer-employee relationship and is not limited to work actually
performed. See Nierotko, 327 U.S. at 365-66. As discussed above, the IRS issued
Revenue Ruling 75-44 in 1975, requiring RRTA withholding for payments made to an
at-will railroad employee who received payments in exchange for his seniority rights.
See 1975-1 C.B. 15. NDSU's only basis for arguing that its duty to withhold was not
clear is that the administrators were paid under the same program as the tenured
faculty, who had clear contractual and constitutional rights not to be terminated at all.
This point establishes a significant distinction between the two groups of employees
and does not support NDSU's decision to stop withholding from payments to the
administrators. Additionally, NDSU's reliance on the letter received from the SSA does
not further its decision to stop withholding from payments made to the administrators.
NDSU requested information from SSA regarding its tenure buy-out program, not
regarding the administrators who also participated in the program. NDSU's obligation
to withhold FICA taxes from payments made to at-will administrators, subject only to
extended notice prior to termination, was clear in 1991. NDSU is liable for its failure
to withhold FICA taxes from payments made to the administrators for the periods
between 1991 and 1995, when it did not withhold the taxes.




                                           III.

      For the foregoing reasons, we affirm the district court's judgment.
