Jane Donaho appeals a district court order granting summary judgment in favor of her employer, FMC Corporation (FMC), in this suit to enforce her rights under an ERISA health benefits plan. See 29 U.S.C. § 1132(a)(1)(B). Under a deferential standard of review, the district court upheld FMC’s decision to deny Donaho’s application for long-term disability benefits under FMC’s employee-funded disability plan. Donaho contends that the denial of benefits is unreasonable and not supported by substantial evidence. Because we conclude that FMC’s denial of benefits to Donaho, at least until October 1993, was an abuse of discretion, we reverse and remand.
I. FACTUAL AND PROCEDURAL BACKGROUND
Jane Donaho was hired as a full-time employee of FMC Corporation in 1990. She held the position of senior software engineer at FMC’s Naval Systems Division, where her duties included planning, designing and writing computer software with military applications. Donaho’s position at FMC was demanding, requiring that she possess a very high level of analytical ability and communication skills to enable her to design complex *896 software, solve difficult technical problems and provide assistance to project leaders.
Donaho continued working full time at FMC until July 14, 1992, when she collapsed at work. Recurrent depression caused her collapse and subsequent inability to work. Donaho underwent psychological treatment with her psychotherapist, Dr. Patricia Al-etky, and saw a psychiatrist, Dr. Deanna Bass, who prescribed Prozac for the illness. In November 1992, Dr. Aletky approved Do-naho for part-time work at FMC; however, Donaho’s condition worsened after two weeks and she could not continue working.
FMC maintains an employee-funded benefits plan which includes both short-term and long-term disability benefits. During the initial period of her illness, Donaho collected short-term disability benefits. 1 On January 12, 1993, when these benefits expired, Dona-ho applied for long-term disability (LTD) benefits. Under FMC’s LTD plan, employees are entitled to LTD benefits if they are totally disabled, providing that they have satisfied a six-month qualifying period. For the first two years of disability, an employee is considered totally disabled when she is “wholly and continuously unable to perform every duty of [her] own job with FMC.” Appellant’s App. at A-150.
To evaluate Donaho’s initial application for LTD benefits, and pursuant to standard policy, the plan administrator retrieved Donaho’s personal, vocational and medical records. Dr. Richard Zaloudek, the plan administrator’s medical director and consulting psychiatrist, reviewed Donaho’s entire record and determined that she was not totally disabled. Specifically, Dr. Zaloudek reviewed Dr. Aletky’s patient notes and determined that Donaho had shown overall improvement since February 1993 and that her depression had improved in late 1992. Further, Dr. Zalou-dek found no evidence of “cognitive deficits or psychomotor abnormalities.” Dr. Zalou-dek approved of this “not totally disabled” evaluation prior to April 2,1993.
In addition to the medical review, FMC director of employee benefits Kenneth J. Morrissey discovered that Donaho had been assisting in the preparation of, and actively participating in, professional meetings and volunteer projects since late 1992 (although Donaho spent only a few hours per month on these activities). On the basis of this information, plus the medical review, Morrissey rejected Donaho’s application for LTD benefits on April 2,1993.
On May 27, 1993, Donaho filed an appeal with the plan administrator. In support of her appeal, Donaho included a letter from Dr. Aletky (dated May 25, 1993) that stated that Donaho was not currently able to perform every duty of her own job and that a return to full-time employment would create a “serious likelihood of relapse.” 2 Appellant’s App. at A-111. Donaho later sent to the plan administrator a letter from Dr. Bass (dated June 23, 1993) which stated that Donaho’s symptoms of impaired concentration and fatigue would “make it extremely difficult to attend consistently to the details that are involved in [Donaho’s] work.” Appellant’s App. at A-104. Bass further noted that Donaho’s depression would “most certainly interfere” with her ability to perform every duty of her job on a regular, sustained basis. Id. Finally, Donaho submitted an evaluation performed by Dr. Bass on April 26, 1993. In this evaluation, Dr. Bass concluded that “the patient has not returned to normal baseline mood and in fact would not be considered in partial remission since mood would plummet ... if stress increased_” 3 Appellant’s App. at A-123.
*897 Dr. Zaloudek, having reviewed the letters of Drs. Bass and Aletky, concluded on July 1, 1993 that “[s]ince the new evidence from Dr. Bass and Dr. Aletky are in close agreement, I would accept their conclusions. It appears now that the client did not have sufficient improvement to function appropriately as a computer software engineer.” Appellant’s App. at A-106.
However, after Dr. Zaloudek was contacted by the plan administrator, he reversed course and stated that Dr. Bass and Dr. Aletky did not provide “sufficient objective measurement of attention span, memory and concentration ...” (Appellant’s App. at A-101), and he recommended that a complete independent medical examination (IME) be performed.
Donaho’s IME was conducted on September 1, 1993 by Dr. Abuzzahab. He determined that Donaho suffered from a mild but recurrent depression that would be amenable to drug treatment. Dr. Abuzzahab concluded that, while Donaho had only a limited ability to complete assigned tasks and to function independently, she “should respond to the suggested pharmacologic approaches, and thus she will be able to resume working” (emphasis added). Appellant’s App. at A-51. Dr. Abuzzahab did not state that Donaho had already recovered; rather, his conclusions indicate that Donaho was still disabled but could recover in the future. His report was forwarded to the plan administrator on October 1,1993.
Dr. Zaloudek reviewed Dr. Abuzzahab’s findings. Dr. Zaloudek noted that “Dr. Abuzzahab did not find any significant cognitive problems. [Donaho’s] memory was fine.” He concluded that “while [Donaho] has not completely recovered, there is no objective evidence to show marked impairment in attention, memory, and concentration .... [She is] not totally prevented] from carrying out her software engineer duties as routinely expected.” (Emphasis added). Appellant’s App. at A-49. This report was dated October 20,1993.
In addition to these medical reports, Dona-ho was requested to execute a release of information permitting FMC to obtain and review her application files from the Social Security disability program. While Donaho’s file revealed that she had been denied Social Security benefits, 4 one finding is instructive: Donaho was able to “understand, remember, and follow through with moderately difficult instructions.” Appellant’s App. at A-96.
Morrissey reviewed all of the materials received and prepared a report for the Employee Benefits Welfare Committee. The Committee met on January 6, 1994, and it determined that Donaho was not “totally disabled” within the meaning of the plan. Specifically, the Committee found that “by late 1992 Ms. Donaho could perform all of the duties of her job as a senior software engineer on a full-time basis.” Appellant’s App. at A-118. Accordingly, Donaho was denied all LTD benefits.
After the Committee rejected Donaho’s application for LTD benefits, Donaho filed suit under the Employee Retirement Income Security Act (ERISA), 29 U.S.C. § 1132(a)(1)(B), claiming that LTD benefits were wrongfully denied her. The district court granted summary judgment in favor of the defendants, determining that the Committee’s decision to withhold LTD benefits was neither “extraordinarily imprudent” nor “extremely unreasonable.” This appeal followed.
II. STANDARD OF REVIEW
We review a grant of summary judgment
de novo. LeBus v. Northwestern Mut. Life Ins. Co.,
While ERISA itself does not specify the standard of review,
see
29 U.S.C. § 1132(a)(1)(B), the Supreme Court has held that a reviewing court should apply a
de novo
standard of review unless the plan gives the “administrator or fiduciary discretionary authority to determine eligibility for benefits or to construe the terms of the plan.”
Firestone Tire and Rubber Co. v. Bruch,
FMC’s employee health benefits plan grants explicit discretionary interpretive authority to the plan administrator:
FMC, as Plan Administrator, has discretionary authority to construe and interpret the terms of the Plan, including, but not limited to, deciding all questions of eligibility. ...
Appellant’s App. at A-162. We agree with the district court that this plan language requires that courts apply a deferential standard of review to the Committee’s plan interpretation and fact-based disability determinations. We review
de novo
a district court’s application of the deferential standard of review.
Bolling v. Eli Lilly and Co.,
This deferential standard “does not permit a reviewing court to reject a discretionary trustee decision with which the court simply disagrees[.]”
Cox I,
The “extraordinarily imprudent or extremely unreasonable” language, first stated in
Cox I,
The starting point for our analysis is the Supreme Court opinion in
Bruch.
As the Court noted, “ERISA abounds with the language and terminology of trust law.... In determining the appropriate standard of review for actions under § 1132(a)(1)(B), we are guided by principles of trust law.”
Bruch,
In defining an abuse of discretion, the Restatement (Second) of Trusts notes that “the court will not interfere unless the trustee in exercising or failing to exercise the power ... acts beyond the bounds of a reasonable judgment.” Restatement (Second) of Trusts § 187, cmt. e (1959). This reasonableness standard has generally been followed by commentators.
See, e.g.,
3 W. Fratcher Scott on Trusts § 187, at 14-15 (4th ed. 1988) (trustee abuses her discretion when she “acts outside the bounds of a reasonable judgment”); Bogert & Bogert,
supra,
§ 559 at 169-71 (where trustee given power to construe disputed terms, her decision will not be disturbed if reasonable),
quoted in Bruch,
We are aware that the word “reasonable” possesses different connotations.
8
As in
Cox I,
we reject any definition of reasonableness that would “permit a reviewing court to reject a discretionary trustee decision with which the court simply disagrees[.]”
Cox I,
*900
In evaluating whether a plan administrator’s fact-based disability determinations are reasonable, courts should look to whether the decision is supported by substantial evidence.
10
Thus, under the abuse of discretion standard of review, the district court, in the absence of bad faith or conflict of interest, may overturn a decision of the plan administrator only if it is “ “without reason, unsupported by substantial evidence or erroneous as a matter of law.’ ”
Abnathya v. Hoffmann-La Roche, Inc.,
Our conclusion that “substantial evidence” is only a quantified reformulation of reasonableness has support in the case law. Under the substantial evidence standard of review, as under the reasonableness standard, “so long as the [plan committee’s] findings are
reasonable,
they may not be displaced on review even if the court might have reached a different result had the matter been before it
de novo.” Laro Maintenance Corp. v. NLRB,
III. ABUSE OF DISCRETION
We apply the foregoing standard to the issues here. Under FMC’s LTD plan, an eligible participant is entitled to LTD benefits after a six-month qualifying period of total disability. Because Donaho first became disabled in July 1992, her qualifying period did not end until January 1993. The benefits committee, however, concluded that “by late 1992 Ms. Donaho could perform all of the duties of her job as a senior software engineer on a full-time basis,” (Appellant’s App. at A-118), and it thus denied Donaho’s application for LTD benefits. This determination lacks support in the record.
Certain facts are central to our holding that the plan administrator acted unreasonably. On July 1, 1993 Dr. Zaloudek accepted the conclusions of Dr.'Bass and Dr. Aletky that Donaho had not completely recovered. Then, after talking with the plan administrator, Dr. Zaloudek reversed course and ordered a complete IME for Donaho. The IME, performed by Dr. Abuzzahab, indicated that Donaho suffered from a continuing disability which could be overcome by medication. Dr. Zaloudek, who was not a treating physician, then misconstrued Dr. Abuzzahab’s findings. In his October 20, 1993 report, Dr. Zaloudek first stated that Donaho had not completely recovered and then, without more, he leapt to the conclusion that Donaho was “not totally prevented] from carrying out her software engineer duties-” Appellant’s App. at A-49.
The unreasonableness of a plan administrator’s decision can be determined by both the quantity and quality of the evidence supporting it. We find the evidence support *901 ing the decision lacking on both counts. First, the evidence indicating continuing disability was overwhelming. 12
Second, the only evidence supporting the committee’s decision,
13
Dr. Zaloudek’s October 20, 1993 evaluation, is not as determinative as the committee would have us believe. Dr. Zaloudek was a reviewing physician; he never examined Donaho. While this fact alone is not dispositive, it lessens the weight which the committee should have accorded Dr. Zaloudek’s opinion. We have held, in Social Security cases, that a reviewing physician’s opinion is generally accorded less deference than that of a treating physician,
Thompson v. Bowen,
Further, while Dr. Zaloudek’s opinions have been largely supportive of the committee’s findings, they have not always been consistent. As we have already observed, on July 1, 1993, Dr. Zaloudek agreed with Dr. Bass and Dr. Aletky that “[i]t appears now that the client did not have sufficient improvement to function appropriately as a computer software engineer.” Appellant’s App. at A-106. Only after being contacted by the plan administrator did he reverse course and order an IME. This change of opinion should also lessen the weight that the committee gave to Dr. Zaloudek’s opinion.
In prior cases, we have held that where there is a conflict of opinion, the plan administrator does not abuse his discretion in finding that the employee is not disabled.
See Cox II,
IV. CONCLUSION
Having determined that the committee’s denial of disability benefits was an abuse of discretion, we vacate the grant of summary judgment and remand to the district court. The district court should in turn remand this case to the plan administrator and require the plan administrator to acknowledge liability at least until October 1,1993, and for such additional time as the record may show that Donaho’s condition remained the same or worsened after October 1993. The adminis *902 trator of the plan should permit additional evidence to determine the duration of the disability, if any, following October 1, 1993.
Notes
. To be eligible for short-term benefits, an employee must have an illness so severe that she is unable to "perform the necessary duties of [her] job or another job for which [she was] or could be qualified by virtue of experience, training or education." Appellant’s App. atA-184.
. Dr. Aletky’s May 25 letter further noted that Donaho “has had no remission of her depression since its onset" and that she “was not able to perform every duty of her job at FMC on a sustained, regular basis at any point [between July 1992 and May 1993]." Appellant's App. at A-110.
.In this evaluation, Dr. Bass also noted that, while Donaho did not exhibit “abnormalities of speech or psychomotor behavior,” (Appellant's App. at 122), her fatigue increased during the months of January, February and March 1993. Further, while Donaho did not seem "severely *897 depressed” during this time period, her depression worsened near the end of March 1993.
. To be eligible for benefits under Social Security, "you must have a severe impairment, which makes you unable to do your previous work or any other substantial gainful activity which exists in the national economy." 20 C.F.R. § 404.1505(a) (1992). This standard is much more restrictive than FMC's LTD benefits standard, which requires for eligibility that a person be unable to perform “every duty of [her] own job with FMC.”
. Some courts continue to use the
pre-Bruch
formulation of "arbitrary and capricious,”
see, e.g., Perry v. United Food & Com. Workers Dist. Unions,
. The
Cox I
court noted that " ‘if the action of the trustee is extraordinarily imprudent or extremely unreasonable, the court is likely to find that there has been an abuse of discretion.’ ”
Cox I,
.
See, e.g., Crosby v. Crosby,
. Reasonableness can mean either "fair, proper, just, moderate” or "not immoderate or excessive." Black’s Law Dictionary (6th ed. 1991).
. While
Krawczyk
deals with plan interpretation rather than plan application, its reasoning applies in both situations.
See, e.g., Block v. Pitney Bowes Inc.,
When determining whether an administrator's plan interpretation is reasonable, this circuit uses the five-factor test enunciated in Finley, 957 F.2d *900 at 621. Where, however, an administrator evaluates facts to determine the plan’s application in a particular case, such as here, the substantial evidence test governs our review.
. Substantial evidence “means such relevant evidence as a reasonable mind might accept as adequate to support a conclusion.”
Consolidated Edison Co. v. NLRB,
. That reasonableness and substantial evidence are really two formulations of the same standard is made more evident by comparing the pre-
Bruch
"arbitrary and capricious” standard to the
post-Bruch
"abuse of discretion” standard. Under the deferential arbitrary and capricious standard, courts would uphold a plan administrator's decision if it was supported by substantial evidence.
See Short v. Central States, S.E. &
S.W.
Areas Pen. Fund,
. All three examining physicians determined that Donaho was totally disabled. Dr. Abuzza-hab determined that Donaho had only a limited ability to complete assigned tasks and function independently and he clearly indicated that Do-naho was still disabled as of October 1, 1993. Dr. Aletky, a treating physician, stated that Dona-ho "has had no remission of her depression since its onset” and that she "was not able to perform every duty of her job at FMC on a sustained, regular basis at any point [between July 1992 and May 1993].” Appellant's App. at A-110. Dr. Bass, also a treating physician, stated that Donaho’s symptoms of impaired concentration and fatigue would “make it extremely difficult to attend consistently to the details that are involved in [Donaho's] work,” (Appellant's App. at A-104), and she concluded in her April evaluation that “the patient has not returned to normal baseline mood and in fact would not be considered in partial remission since mood would plummet ... if stress increased....” Appellant's App. at A-123.
. The committee erroneously relied on the Social Security Administration's rejection of Dona-ho's application for Social Security disability benefits. The Social Security Administration concluded that Donaho could "understand, remember, and follow through with moderately difficult instructions” (Appellant's App. at A-96), and thus she could function as a “data entry operator.” This does not support the committee’s decision that Donaho could function as a computer software engineer, a very demanding occupation.
The committee also erroneously relied on evidence of Donaho’s personal life, including social activities. That she can get out of bed, take care of herself, interact with others, and spend a few hours per month on professional activities (most often only attending functions and perhaps making a few phone calls) does not demonstrate that she can resume working at a stressful and demanding job.
