From June 20, 1960, until his death from pancreatic cancer on June 14, 1991, David Swaback was an employee of Illinois Bell and was a participant in the Ameritech Management Pension Plan (“AMPP”). The AMPP provides a procedure by which a participant who has a vested pension with a present value of greater than $3,500 can elect a lump sum payout of that pension upon retirement. The plan requires participants to elect this option, in writing, at least thirty days in advance of retiring. The district court found that Mr. Swaback had failed to elect the lump sum payment because he had not given Illinois Bell the requisite notice. Gail Swabaek, Mr. Swaback’s widow and administratrix for his estate, appeals this decision. For the reasons that follow, we reverse, in part, the judgment of the district court and remand the case with direction to enter judgment for Mrs. Swaback on her section 502(a)(1)(b) ERISA claim.

BACKGROUND
A. Facts
David Swaback, deceased, had been employed by Illinois Bell (“Bell”), a subsidiary of Ameritech Information Technologies Corporation (“Ameritech”), as a management level employee from June 20, 1960 until his death on June 14, 1991. Bell was a participating company in the AMPP,
Mr. Swaback was diagnosed with pancreatic cancer in June 1990. By September, he was no longer able to work for the company and began receiving benefits under Ameritech’s Sickness and Accident Disability Benefits Plan (“SADP”).
In late Aрril or early May, Annette Goetz, the Bell staff manager for benefits, called Mr. Swaback to discuss his retirement options with him. During this conversation, Mr. Swaback said that he wanted to retire and was interested in the lump sum option. He also indicated that he would prefer that Ms. Goetz bring the pension papers to him for his signature rather than his traveling into Bell’s offices. She agreed, and they arranged an appointment for May 8, 1991, at which she would bring the necessary paperwork to his home. The day before the meeting was to take placé, however, Ms. Goetz received a note from her supervisor, Don Hattendorf, explaining that the appointment would likely be canceled. It was.
. The following month, Mrs. Swaback filed a claim with the Bell Committee for Mr. Swaback’s service pension in the form of a lump sum. On August 20, 1991, the Bell Committеe denied Mrs. Swabaek’s claim because her husband had been on SADP status and had not been medically approved to return to work. According to the Bell Committee, Mr. Swaback, as someone receiving SADP benefits, was in the class of people excluded by section 4, para. 12(b) of the AMPP from choosing the lump sum pension option. Mrs. Swaback appealed this determination to the Ameriteeh Committee, which similarly denied her 'claim for the lump sum. The Ameritech Committee reiterated that to choose the lump sum, Mr. Swaback would have needed to return to work, requiring approval from Bell physicians, and tо make the lump sum election thirty days prior to his retirement. Mrs. Swaback then filed suit in district court, challenging this interpretation of the AMPP. Her complaint alleged violations of various provisions of ERISA, federal common law violations, and a pendent state law claim.
B. District Court Proceedings
1. Magistrate Judge’s Report and Recommendation
On March 24, 1995, the parties filed cross-motions for summary judgment. On June 15, 1995, the magistrate judge issued his Report and Recommendation on these motions. In reviewing the Ameriteeh and Bell Committees’ decisions, he found the AMPP proviso dealing with the lump sum option to be ambiguous. The magistrate judge also determined that the committees reasonably looked to the Summary Plan Description (“SPD”)
2. District Court Order
The district court disagreed with much of the magistrate judge’s analysis. It agreed with Mrs. Swaback that Ameritech should not have relied upon thе SPD. The court noted that, in instances in which the SPD and AMPP differ, the SPD explicitly provides that the AMPP is controlling. The district court, in reading the AMPP, viewed the plan as clear and unambiguous. The AMPP, according to the district court, sets out five prerequisites to an employee’s election of a lump sum in lieu of a service pension: (1) The present value of the pension is greater than $3,500; (2) the service pension is not one converted from a disability pension; (3) the pension is not payable to someone who could elect a disability pension; (4) the election of the lump sum payment must be in writing; and (5) the written election must be made mоre than thirty days prior to the retirement date. In the district court’s view, the AMPP simply does not contain any requirements that an employee be medically approved before electing the lump sum or that he be on the “active payroll.” Further, the district court determined that the magistrate judge was mistaken in concluding that Mr. Swaback was not an employee for purposes of the-lump sum proviso. Because he received regular and stated payments — compensation—from Ameritech due to his having worked for Bell, Mr. Swaback was a Bell employee. However, the district court held that Mrs. Swaback was not entitled to the lump sum payment because her late husband had not elected the lump sum payment in writing at least thirty days before his retirement; in fact, he had never made the election before his death. Mrs. Swaback appeals.

DISCUSSION
We focus primarily on Mrs. Swaback’s section 502(a)(1)(B) ERISA claim.
A. Standard of Review
We review a district court’s decision to grant summary judgment de novo. Buck
In reviewing a denial of benefits under ERISA section 502(a)(1)(B), 29 U.S.C. § 1132(a)(1)(B), we look to the principles laid down in Firestone Tire & Rubber Co. v. Bruch,
B. Section 502(a)(1)(B) Claim
1. District Court’s Grant of Summary Judgment
ERISA plans must be in writing. 29 U.S.C. § 1102(a)(1) (“Every employee benefit plan is to be established and maintained pursuant to a written instrument.”). ERISA further provides that a fiduciary is to discharge his duties with respect to the plan “in accordance with the documents and instruments governing the plan.” 29 U.S.C. § 1104(a)(1)(D). Although we review the committees’ actions in a deferential light, we shall not rubber stamp their decisions. See Donato v. Metro. Life Ins. Co.,
In addition, we note that, because the case was brought pursuant to ERISA, federal common law principles of contract interpretation govern.
With these principles firmly in mind, we turn to the Ameriteeh and Bell Committees’ interpretation оf the AMPP. After reviewing the AMPP, we conclude that the district court was correct in concluding that the AMPP did not contain Ameritech’s phantom requirements — that Mr. Swaback had to return to work and had to be medically “OK’d” to return to work. Section 4 of the AMPP deals with employee pensions. Paragraph 1(a) sets out the eligibility requirements for employee service pensions: “Subject to the provisions set forth elsewhere in this plan, ... all employees regardless of age whose terms of employment have been at least thirty years shall, if they leave the service of [Bell] for any reason ..., be retired from active service and, upon such retirement, shall be granted service pensions.” R. 17 at 65. Paragraph 12(b) allows those employees whose service pension’s present value exceeds $3,500 to elect a lump sum distribution for their service pensions in lieu of the monthly payments. That proviso states:
If the present value of the monthly service pension ... payable under paragraph 1 of this section 4 (excluding any service pension either converted from a disability pension or payable to someone who could elect to receive a disability pension) exceeds $3,500 as of the date on which the employee retires, ... the employee may elect to receive a lump sum distribution of such present value, subject to ... the following:
(i) Any election under this Paragraph 12(b) by an employee who is entitled to a service pension must be in writing filed with the Committee no later than 30 days prior to the date as of which he voluntarily retires____
Id. at 109-10: Our reading of this language is in accord with that of the district court. We agree that the AMPP’s only service pen- ■ sion eligibility requirements are the term-ofserviee and age requirements and that the AMPP imposes only five conditions on the election of the lump stun option: (1) The present value of the pеnsion must be greater than $3,500; (2) the service pension must not be one converted from a disability pension; (3) the pension must not be payable to someone who could elect a disability pension; (4) the election of the lump sum payment must have been in writing; and (5) the written election must have been made more than thirty days prior to the retirement date. We, like the district court, find these clear and unambiguous requirements dictated by the language of the AMPP.
Unlike the legal issue of the AMPP’s interpretation, the material facts are not in dispute: Mr. Swaback was eligible for a service pension; it had a present value greater than $3,500; and it was not a service pension converted from а disability pension. The district court also noted that the parties agreed that Mr. Swaback, at the time he wanted to retire, could not elect a disability pension.
We previously held that, if employees havе been deterred, by an employer’s- misrepresentation, from electing retirement benefits to which they were entitled, they can maintain an ERISA action for those benefits. To prevail in such an action, we said, they must “present the court with a factual record detailing their attempt to retire and the company’s action in misinforming them.” Meredith v. Allsteel, Inc.,
Turning to the facts here, Mr. .Swaback made clear to Ameritech that he wanted to retire and that he was interested in selecting the lump sum payment rather than his monthly service pension. Annette Goetz testified in her depositiоn that Mr. Swaback told her that he wanted to retire and to take the lump sum, but she explained to him that he would be unable to do so unless he would come back to work for at least thirty days.
2. District Court’s Denial of Partial Summary Judgment
Mrs. Swaback also appeals the district court’s denial of her motion for partial summary judgment. Ordinarily, denials of summary judgment are not appealable because we are authorized to review only final judgments.
Because we believe that this case presents no genuine issue of material fact, and both parties have briefed and responded to the cross-motions for summary judgment,
III
CONCLUSION
For the foregoing reasons, we affirm in part and reverse and remand in part this cause for proceedings not inconsistent with this opinion. Mrs. Swaback may recover her costs in this court.
AFFIRMED IN PART; REVERSED AND REMANDED IN PART.
Notes
. The relevant provision of the AMPP at the heart of this lawsuit is section 4, para. 12(b), Elective Lump Sum Distribution:
If the present value of the monthly service pension ... payable under paragraph 1 of this section 4 (excluding any service pension either converted from a disability pension or payable to someone who could elect to receive' a disability pension) exceeds $3,500 as of the date оn which the employee retires, resigns or is dismissed, the employee may elect to receive a lump sum distribution of such present value, subject to .., the following:
(i) Any election under this Paragraph 12(b) by an employee who is entitled to a service pension must be in writing filed with the Committee no later than 30 days prior to the date ás of which he voluntarily retires____ Such 30 day period shall, in the case of a retirement by an active employee for reasons other than health, be reduced by the number of the employee's current year's vacation and personal days as of his date of retirement.
R.17 at 109-10. Paragraph 1 of section 4 establishes the eligibility requirements for service pensions under the plan: pertinent here, 30 years of service, regardless of age.
. Under the SADP, Mr. Swaback qualified to receive payments due to his inability to work by reason of sickness. Because he had worked for the company for at least 25 years, he could receive "full pay” benefits for up to 52 weeks.
. The record does not make clear whether Mr. Swaback or Bell canceled the May 8 meeting.
. There is no dispute that, at the time of this appointment, Mr. Swaback was not medically capable of returning to work full time.
.The SPD provides: "Employees who retire or terminate immediately ... after the termination of disability benefits may not elect a lump sum.” R.17 at 210.
. Section 502(a)(1)(B) of ERISA provides in pertinent part: "A civil action may be brought by a participant or beneficiary to recover benefits due to him under the terms of his plan____” 29 U.S.C. § 1132(a)(1)(B).
. The AMPP, section 3, para. 4, provides: "The Committee shall determine conclusively for all parties all questions arising in the administration of the [AMPP]...." R.17 at 61.
. Relying on cases in which we found the plans under review to confer upon administrators sufficient discretionary authority to warrant deferential review, the magistrate judge concluded that the AMPP grants the Ameritech administrators significant discretion and that a deferential standard should apply. The district court accepted this finding because Mrs. Swaback did not object specifically to it.

.GCIU Employer Retirement Fund v. Chicago Tribune Co.,
. Meredith,
. Ameriteeh contends that this language is ambiguous as to whether an employee must retire from the active payroll to elect the lump sum. Given this ambiguity, Ameriteeh maintains, it was not arbitrary and capricious for the committees to look at extrinsic evidence, such as the SPD (which explicitly states that an employee in Mr. Swaback’s situation cannot elеct the lump sum), and to determine that Mr. Swaback, although meeting the requirements for a monthly service pension, did not meet the requirements to receive the present value of that service pension. Because we find that the AMPP is unambiguous in not imposing the additional requirements on the lump sum option, we cannot agree that Ameritech could have gone outside the plan to the SPD for interpretive guidance. See GCIU,
.Ameritech's reading of para. 12(b) is strained. Ameriteeh asks us to accept that para. 12(b)’s brief parenthetical is a shorthand reference to a group of people excluded from being able to elect the lump sum. Ameriteeh reads the parentheti
. See Filipowicz,
. Employees are entitled to a disability pension only after they have exhausted all 52 weeks of SADP benefits. Mr. Swaback had not exhausted these benefits and therefore, at the time of his death, was not someone who could have elected a disability pension.
. See Restatement (Second)-of Contracts § 225, cmt. b (1981) ("The non-occurrence of a duty ... may be excused by prevention or hindrance of its oсcurrence through a breach of the duty of good faith and fair dealing....”); Arthur L. Corbin, Corbin on Contracts § 767 (1960) (“One who unjustly prevents the performance or the happening of a condition of his own promissory duty thereby eliminates it as such a condition. He will not be permitted to take advantage of his own wrong____").
. We note the congruity of this analysis with our ERISA estoppel jurisprudence. We held in Thomason v. Aetna Life Ins. Co., that the doctrine of estoppel has not been preempted by ERISA. See
. Because Ameritech must use operating funds to ensure the actuarial soundness of the AMPP and to make up any shortfalls in the AMPP, see AMPP, section 4, para. 8, its refusal to pay the lump sum redounds to its benefit.
. In Ms. Goetz’s deposition, when responding to the question of whether Mr. Swaback had told her that “he wanted to retire and take a lump sum,” she responded, "He did, yes, but he would have had to have been back on the active payroll for at least 30 days.” R. 120, Tab 9 at 22.
. In this note, Mr. Swaback manifеsts his intention to "retire" and to "care for [his] family w[ith the] lump sum [pension].” R. 127 at 398.
. In addition to these individuals' oral communication of the additional requirements to Mr. Swaback, Ameritech, well before Mr. Swaback became ill, distributed to him a copy of the SPD, which explicitly informs employees that they cannot take the lump sum pension after receiving SAD.P benefits unless they first returned to work for thirty days.
. 28 U.S.C. § 1291; see Whitford v. Boglino,
. See UAW v. Randall Div. of Textron, Inc.,
.See Glass v. Dachel,
. There is no disagreement between the parties on the crucial factual elements for disposing of this case: Mr. Swaback qualified for a service pension; he expressed his desire to retire from Bell with a lump sum; Ameritech repeatedly, in . writing and orally, told him that he could not do so unless he first returned to work; and Mr. Swaback, repeatedly confronted with these statements, did not meet the written election requirement. The case, throughout this litigation, has turned on the interpretation of the AMPP, a legal issue. We recognize that there is a genuine issue of fact over who canceled the May 8 meeting, but this fact is not material. Through its repeated misrepresentations, Ameritech prevented Mr. Swaback from electing the lump sum.
. We need not reach her other federal claims that request duplicative relief. The judgment of the district court with respect to the pendent state claim is affirmed because Mrs. Swaback failed to make a specific objection to the Report and Recommendation of the magistrate judge. See Fed.R.Civ.P. 72(b).
