Opinion for the court filed by Circuit Judge PROST.
Concurring opinion filed by Senior Circuit Judge PLAGER.
PROST, Circuit Judge.Gayle J. Snyder petitions for review of the final order of the Merit Systems Protection Board (“Board”). The Board affirmed the decision of the Office of Personnel Management (“OPM”) denying the petitioner’s claim for survivor annuity benefits under the Civil Service Retirement System (“CSRS”) as the former spouse of Robert L. Ruff. Snyder v. Office of Pers. Mgmt., No. CH0842040399-I-1, 99 M.S.P.R. 215 (M.S.P.B. July 27, 2005). We vacate and remand.
BACKGROUND
Gayle Snyder and Robert Ruff divorced in 1993 after over thirty years of marriage. The Wisconsin divorce court entered an order entitled “Addendum to Marital Settlement Agreement for Qualified Domestic Relations Order-Federal (CSRS) Plan” (“Court Order”). The Court Order was submitted to OPM which notified Snyder that the order was suitable for processing and would provide her with (1) an apportionment benefit payable on Ruffs retirement, and (2) a survivor annuity payable upon his death.
Ruff was an employee of both federal and state governments during the entire marriage. Several years after the divorce, in July 2001, he retired from federal government service. Although OPM had previously notified Snyder that the Court Order was sufficient to provide her with a survivor annuity, it changed its determination. Between 2001 and 2004, Snyder and OPM exchanged several letters in which OPM made various determinations about the order’s suitability. Finally, in a letter she received March 15, 2004, OPM stated that the order did not comply with OPM’s regulations for the awarding of a former spouse survivor annuity. Snyder appealed OPM’s finding to the Board.
While Ruff lives, the Court Order provides no payments to Snyder prior to Ruffs retirement. After his retirement, the Court Order provides Snyder with 43.11% of the actuarial equivalent value of Ruffs pension benefit which accrued during the period of their marriage.
In providing for Snyder after Ruffs death, the Court Order contains the following provision:
VI. DEATH OF PARTICIPANT AND SURVIVOR BENEFITS — PROVISIONS FOR TREATMENT OF FORMER SPOUSE OF PARTICIPANT AS SURVIVING SPOUSE OF *1340PARTICIPANT FOR PURPOSES OF PRE-RETIREMENT SURVIVING SPOUSE PENSION BENEFIT, (AND/ OR) OTHER SURVIVOR BENEFITS. The assignment of benefits to the Alternate Payee shall not be reduced, abated or terminated as a result of the death of the participant. Pursuant to Section 414(p)(5) of the Code, the former spouse of the Participant, namely Gayle S. Ruff, shall be treated as the surviving spouse of the Participant for purposes of Pre-retirement Survivor benefits accrued during the period described in Section II C about [sic] 4 in accordance with Sections 401(a) (ii) and 417 of the Code.
Snyder argued to the Board that this provision provides her with a post-retirement survivor annuity.
The Board’s administrative judge found that “[t]he only permissible interpretation of the agreement is ... that Appellant is to be treated as surviving spouse only for Pre-retirement survivor benefits.” Snyder v. Office of Pers. Mgmt., No. CH0842040399-I-1, slip op. at 4 (M.S.P.B. Sept.7, 2004). The administrative judge rejected Snyder’s argument that the first sentence of Section VI must provide for post-retirement survivor benefits. Rather, he found that it meant that “any Pre-retirement lump sum payment shall not be reduced, abated or terminated as a result of the death of the Participant.” Id., slip op. at 5.
The administrative judge also noted that Snyder argued that it was the parties’ intent to provide her with a lifetime benefit, but held that because the Court Order is clear and unambiguous on its face, the use of parol evidence would be inappropriate. Id. Nevertheless, the administrative judge noted that Ruffs testimony was credible and consistent with his interpretation of the order. Id.
The administrative judge’s initial decision became the final decision of the Board after the Board denied the petition for review. This appeal followed. We have jurisdiction pursuant to 28 U.S.C. § 1295(a)(9).
DISCUSSION
Board decisions may be set of aside if they are “(1) arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with the law; (2) obtained without procedures required by law, rule, or regulation having been followed; or (3) unsupported by substantial evidence .... ” 5 U.S.C. § 7703(c) (2000).
Within the CSRS, a post-retirement survivor annuity provides the survivors of an employee with recurring payments. A former spouse may participate as a survivor to an employee’s survivor annuity pursuant to statute:
a former spouse of a deceased employee ... is entitled to a survivor annuity ... if and to the extent expressly provided for ... in terms of any decree of divorce or annulment or any court order or court-approved property settlement agreement incident to such decree.
5 U.S.C. § 8341(h)(1) (2000) (emphasis added). OPM’s regulations provide further guidance regarding how a survivor annuity must be described in a court order in order to properly provide the former spouse with a survivor annuity. 5 C.F.R. §§ 838.801-807.
On appeal, Snyder argues, as she did to the Board, that Section VI of the Court Order entered at her divorce provides her with a post-retirement survivor annuity. She asserts that the Board erred in its determination that the first sentence of the section provided only a pre-retirement benefit. Rather, she argues that the intent of the parties and the clear language of the agreement evince the meaning of the order — to provide her with a lifetime benefit. She argues that the administra-*1341five judge erred in permitting Ruffs testimony regarding the intent of the agreement while excluding hers. She also argues that because OPM waited until after her former spouse’s retirement to rescind its initial decision, it should be estopped from doing so.
A.
First, we address the administrative judge’s finding regarding the meaning of Section VI of the Court Order. Snyder concedes that the second sentence of Section VI means only that she will be treated as the survivor for purposes of a pre-retirement survivor benefit. However, she disagrees with the administrative judge’s finding that the first sentence of the section also refers to a pre-retirement surviv- or benefit. The first sentence states, “The assignment of benefits to the Alternate Payee shall not be reduced, abated or terminated as a result of the death of the participant.” Since the only benefits to which she was entitled under the agreement were a portion of Ruffs pension, Snyder argues that this was the benefit that should not be reduced as a result of his death. Snyder also states that the administrative judge may have reached an erroneous conclusion based on a finding that Snyder’s benefits would necessarily decrease if they were converted from being a portion of Ruffs pension to a post-retirement survivor annuity. She states that this was erroneous because a post-retirement survivor annuity is not necessarily less than her apportionment of Ruffs pension.
OPM agrees with Snyder that the administrative judge erred in finding that the first sentence of Section VI refers to a pre-retirement survivor benefit. Agreeing with Snyder’s contentions, OPM states, “[i]t would make no sense to state that survivor benefits cannot be reduced or terminated by the very event that would trigger entitlement to those benefits.” Therefore, OPM agrees with Snyder that “the first sentence of Section VI must address benefits that Snyder was already receiving at the time of Mr. Ruffs death.” That is, the first sentence must be referring to the “portion of Mr. Ruffs retirement benefits [Snyder would be receiving post-retirement] pursuant to Section II.C .... ”
OPM therefore repudiates the administrative judge’s analysis and both parties agree that the administrative judge erred in his rationale for finding that the first sentence of Section VI did not provide for a post-retirement survivor annuity. We therefore proceed to the alternative basis that OPM presents on appeal as to why the first sentence of Section VI is deficient to provide the benefit.
B.
OPM argues that Section VI of the Court Order is deficient for purposes of providing Snyder with a post-retirement survivor annuity because it does not satisfy 5 C.F.R. § 838.803(b). The regulation cited by OPM contains two requirements:
Any court order that provides [1] that the former spouse’s portion of the employee annuity shall continue after the death of the employee or retiree, by using language such as “will continue to receive benefits after the death of’ the employee, that the former spouse “will continue to receive benefits for his (or her) lifetime,” or “that benefits will continue after the death of’ the employee, but does not [2] use terms such as “survivor annuity,” “death benefits,” “former spouse annuity,” or similar terms is not a court order acceptable for processing.
5 C.F.R. § 838.803(b) (2006).
Here, Section VI of the Court Order includes the sentence, “The assignment of benefits to the Alternate Payee shall not be reduced, abated or terminated as a result of the death of the participant.” *1342OPM states that this language is “equivalent to the insufficient language described in the first part of [the OPM regulation],” so that the second condition must be met in order for the clause to be sufficient under the regulation. But, OPM argues, the second condition of its regulation is not met — that is, the court order does not “use terms such as ‘survivor annuity,’ ‘death benefits,’ ‘former spouse annuity,’ or similar terms.” 5 C.F.R. § 838.803(b) (2006).
Snyder responds that several sections of the Court Order refer to a survivor annuity. First, the title of Section VI states that the section covers “PRE-RETIREMENT SURVIVING SPOUSE PENSION BENEFIT, (AND/OR) OTHER SURVIVOR BENEFITS.” The regulation permits use of the term “death benefits” to satisfy its second requirement and the court order uses the term “survivor benefits” in the title to the very section which meets the first prong of the regulation’s test. The government does not argue that the language “other survivor benefits” is not sufficient to satisfy the regulation’s second condition. Rather, during oral argument, OPM argued solely that this section’s reference to “OTHER SURVIVOR BENEFITS” did not meet the requirements of the regulation because it is preceded by the conjunctive term “and/or.” It argued that if benefits other than pre-retirement benefits were expressly intended in the title, the title would not have used the term “and/or.” This court cannot agree that a reference to “survivor benefits” that would otherwise satisfy the OPM regulation becomes insufficient because it is preceded by the term “and/or.”1 We therefore turn to this court’s precedent as to the requirements for “expressly providing” for a survivor annuity.
c.
This court has previously discussed the requirements of how a court order must expressly provide for the award of a survivor annuity as required by 5 U.S.C. § 8341(h)(1). When words such as “CSRS survivor annuity” are used, obviously, a court order will provide for the benefit. However, such “ ‘magic words’ are not required to assign a CSRS survivor annuity in favor of a former spouse.” Fox v. Office of Pers. Mgmt., 100 F.3d 141, 146 (Fed.Cir.1996). When the magic words are not used, Fox provides the analysis a tribunal must undertake to determine whether a court order provides for the survivor benefit. Id.
Specifically, to determine that a court order without any magic words does provide the survivor annuity benefit, the tribunal must first determine whether the order contains a pertinent clause regarding a survivor annuity. Id. If so, then it must inquire whether the operative terms in that clause can “fairly be read as awarding” the annuity. Id. If so, then it must “examine any evidence introduced concerning the marriage parties’ intent and the circumstances surrounding the execution of the document” to interpret the clause. Id. If the evidence only dictates that the “clause refers to a CSRS survivor annuity — then it is legal error to conclude that the document has not ‘expressly provided for’ the award of a survivor annuity” as required by 5 U.S.C. § 8341(h)(1). Id.
Here, there is no dispute that Section VI of the Court Order is a pertinent clause which can fairly be read as providing for a post-retirement survivor annuity. Indeed, the government concedes that the first sentence can only be read to mean that Snyder’s post-retirement benefits would *1343not be reduced due to Ruffs death. This is clearly contemplated by resort to a post-retirement survivor annuity. Under Fox, the Board is thus required to examine evidence, to the extent such evidence exists, to determine whether it dictates another possible meaning for the clause.
CONCLUSION
Because the first sentence of Section VI of the Court Order can fairly be read to refer to a post-retirement survivor annuity, we vacate the Board’s decision and remand for a determination of the meaning of the clause.
VACATE AND REMAND.
. Furthermore, we see no problem with the "and/or” language. The title may provide for pre-retirement "and” post-retirement benefits. However, obviously, Snyder would only actually receive pre-retirement "or” post-retirement survivor benefits.
