Before his death, William David Strong participated in the Omaha Construction Industry Pension Plan (Plan), an employee benefit plan subject to the federal Employee Retirement Income Security Act of 1974, 29 U.S.C. § 1001 et seq. (1994) (ERISA). When William joined the Plan, he designated his wife, Melissa Strong, as his beneficiary for the Plan’s pension death benefit. Although Melissa and William divorced in 1998, William did not remove Melissa as his beneficiary before his death. The district court determined that under the divorce decree, Melissa waived her interest and granted summary judgment to William’s estate (Estate).
We must decide whether under federal law Melissa waived her beneficiary interest in the death benefit by agreeing to the terms of the divorce decree. We conclude that under the federal common law, a divorce decree can waive a beneficiary interest in the death benefit of an ERISA-governed pension plan. Because the unambiguous language of the divorce decree shows that Melissa intended to waive her interest in the death benefit, we affirm the district court’s grant of summary judgment.
*3I. BACKGROUND
Employees eligible for the Plan are provided with a summary plan description that includes a section entitled “How Can I Designate a Beneficiary?” It provides:
Your spouse is your automatic beneficiary but if you do not have a spouse, your beneficiary will be the person or persons you so designate in your latest written notice to the Fund Office. You may change your beneficiary at any time you so desire prior to your death by written notice to the Fund Office.
In the event that you fail to name a beneficiary, the Trustees will pay the Death Benefits to your dependent children, if any, in equal shares. If neither your legal spouse [n]or dependent children survive you, then the Death Benefits will be computed and shall be paid in a one-time lump sum amount to the executor or administrator of your estate.
(Emphasis in original.)
During William and Melissa’s marriage, William signed a beneficiary designation card for the pension, naming Melissa as his beneficiary. William and Melissa divorced in 1998, but before his death in 2000, William did not change the beneficiary designation card. So, the only beneficiary designation provided to the Plan named Melissa. Melissa argues the beneficiary designation card controls to whom the pension death benefit must be paid.
The personal representative, however, argues that Melissa waived any interest she had in the pension death benefit by entering into the divorce decree. The decree provides:
Each of the parties is awarded the ownership of the . . . personal property of every kind and description now in each party’s possession, including bank accounts, automobiles, 40 IK plans, retirement plans, insurance policies, and other intangible property now possessed by each or owned by each in their separate names ....
. . . All property and money received and retained by the parties pursuant hereto, except as specifically provided to the contrary, shall be the separate property of the respective parties, free and clear of any right, interest or claim of the other party and each party shall have the right to deal with *4and dispose of his or her separate property, both real and personal as fully and effectively as if the parties had never been married....
(Emphasis supplied.)
We note that ERISA contains anti-alienation provisions that prevent plan participants from unwisely alienating their interests in ERISA-regulated pension plans. 29 U.S.C. § 1056(d). A qualified domestic relations order (QDRO) is an exception to the anti-alienation rule. Under this exception, persons may alienate their benefits for things such as child support and alimony. 29 U.S.C. § 1056(d)(3). To fall within the QDRO exception, the state domestic relations order must comply with specific requirements set out in 29 U.S.C. § 1056(d)(3). It is undisputed that the divorce decree failed to comply with these requirements and therefore was not a QDRO.
After William’s death, Melissa claimed the pension death benefit. Initially, the Plan agreed to pay her. But William’s personal representative then claimed the death benefit on behalf of the Estate. After receiving the Estate’s claim, the Plan refused to pay the death benefit to either party until it had an order from an appropriate court.
After the Plan refused to pay the pension death benefit, Melissa brought this action. The Estate intervened and moved for summary judgment. After the court denied the motion, Melissa moved for summary judgment. In addition to opposing Melissa’s motion, the Estate moved the court to reconsider the denial of its earlier motion for summary judgment. The court determined that its earlier order was incorrect and granted the Estate summary judgment. Melissa then filed a motion for new trial, which the court overruled.
II. ASSIGNMENTS OF ERROR
Melissa assigns that the court erred in (1) granting the Estate’s motion for summary judgment, (2) failing to grant her motion for summary judgment, and (3) overruling her motion for new trial.
III. STANDARD OF REVIEW
Summary judgment is proper when the pleadings and evidence admitted at the hearing disclose no genuine issue as to any material fact or as to the ultimate inferences that may be *5drawn from those facts and that the moving party is entitled to judgment as a matter of law. Richards v. Meeske, 268 Neb. 901, 689 N.W.2d 337 (2004).
IV. ANALYSIS
1. Jurisdiction
The Estate argues we lack jurisdiction because Melissa failed to file a timely notice of appeal. The trial court entered summary judgment for the personal representative on September 17, 2003. A party must file a notice of appeal within 30 days of the judgment, decree, or final order from which the party is appealing. Neb. Rev. Stat. § 25-1912(1) (Cum. Supp. 2004). A motion for a new trial, however, terminates the time in which a notice of appeal must be filed. § 25-1912(3). And, if the court denies the motion, the party has 30 days from the entry of the order denying the motion to file a notice of appeal.
Here, Melissa filed a motion for new trial on September 24, 2003. The court overruled the motion on November 17, and Melissa filed her notice of appeal on December 15. The Estate, however, argues that a motion for new trial cannot follow a grant of summary judgment and thus that Melissa’s motion for new trial did not terminate the time for filing a notice of appeal. If so, Melissa’s notice of appeal was untimely because she filed it more than 30 days after September 17, the day the court granted summary judgment to the Estate.
A new trial is a reexamination in the same court of an issue of fact after a verdict by a jury, report of a referee, or a trial and decision by the court. Woodhouse Ford v. Laflan, 268 Neb. 722, 687 N.W.2d 672 (2004). Summary judgment proceedings do not resolve factual issues, but instead determine whether there is a material issue of fact in dispute. Id. So, Melissa’s motion following the entry of summary judgment was not a proper motion for a new trial under Neb. Rev. Stat. § 25-1142 (Cum. Supp. 2004).
That, however, does not mean Melissa’s motion failed to terminate the time for an appeal. Neb. Rev. Stat. § 25-1329 (Cum. Supp. 2002) authorizes a motion to alter or amend a judgment. If filed no later than 10 days after the entry of judgment, a motion to alter or amend a judgment, like a motion for a new *6trial, terminates the period in which a party must file a notice of appeal. § 25-1912(3). Thus, if Melissa’s motion qualified as a motion to alter or amend a judgment, she timely filed her notice of appeal.
In determining what qualifies as a motion to alter or amend a judgment, the key is not the motion’s title. If the motion seeks substantive alteration of the judgment — as opposed to the correction of clerical errors or relief wholly collateral to the judgment — a court may treat the motion as one to alter or amend the judgment. See Woodhouse Ford v. Laflan, supra. In her motion, Melissa claimed that there were irregularities in the proceedings and that the court erred on questions of law. For her relief, she sought “an Order granting a new trial” and any other “relief deemed equitable and just.” In effect, she requested that the court reconsider its grant of summary judgment. A motion for reconsideration is the functional equivalent of a motion to alter or amend a judgment. Woodhouse Ford v. Laflan, supra. So, we treat Melissa’s motion as one to alter or amend the judgment. We have jurisdiction.
2. Pension Death Benefit
In brief, the dispute over the death benefit centers on three factors. First, the documents governing the Plan provide: “Your spouse is your automatic beneficiary but if you do not have a spouse, your beneficiary will be the person or persons you so designate in your latest written notice to the Fund Office.” (Emphasis omitted.) Second, the last written notice William had given to the fund office before his death designated Melissa as his beneficiary. Third, between the time William sent the notice and his death, he and Melissa divorced, and, according to the Estate, Melissa waived her beneficiary interest in the pension death benefit by agreeing to the terms of the divorce decree. Who is entitled to the death benefit depends on whether the beneficiary designation or the purported waiver in the non-QDRO divorce decree controls.
(a) Issue Preempted by Federal Law
This case involves an ERISA-governed employee benefit plan. ERISA supersedes “any and all State laws insofar as they may now or hereafter relate to any employee benefit plan” *7covered by the statutory scheme. 29 U.S.C. § 1144(a). This preemption provision is “ ‘deliberately expansive’ and [is] consistently construed to accomplish the congressional purpose of [e]nsuring certain minimum standards in the administration of employee benefit plans.” Manning v. Hayes, 212 F.3d 866, 870 (5th Cir. 2000) (quoting Pilot Life Ins. Co. v. Dedeaux, 481 U.S. 41, 107 S. Ct. 1549, 95 L. Ed. 2d 39 (1987)). Determination of beneficiary status is an area of core ERISA concern. Egelhoff v. Egelhoff, 532 U.S. 141, 121 S. Ct. 1322, 149 L. Ed. 2d 264 (2001) (holding that ERISA expressly preempted state statute providing that designation of spouse as beneficiary on nonprobate asset was automatically revoked upon divorce). Therefore, federal law controls. See, McMillan v. Parrott, 913 F.2d 310 (6th Cir. 1990); Fox Valley & Vic. Const. Wkrs. Pension F. v. Brown, 897 F.2d 275 (7th Cir. 1990) (en banc); Lyman Lumber Co. v. Hill, 877 F.2d 692 (8th Cir. 1989).
(b) Ascertaining Federal Rule
Having concluded that federal law preempts state law, we turn to the more difficult task of ascertaining what the federal rule is. To do this, we “look to either the statutory language or, finding no answer there, to federal common law which, if not clear, may draw guidance from analogous state law.” See McMillan v. Parrott, 913 F.3d at 311. Courts that have considered the same issue presented by this case have split on whether the issue is controlled by the language of ERISA or the federal common law.
Some courts hold that 29 U.S.C. § 1104(a)(1)(D) controls. It provides that plan fiduciaries are to conduct their duties “in accordance with the documents and instruments governing the plan insofar as such documents and instruments are consistent with the provisions of this subchapter and subchapter III of this chapter.” Id. According to these courts, 29 U.S.C. § 1104(a)(1)(D) requires plan administrators to determine a plan’s beneficiary by examining the plan documents. If, as here, the plan documents state that the employee’s beneficiary will be determined by the last written beneficiary designation on file, an attempt to waive a beneficiary interest with language in an extraneous divorce decree is ineffective. See, McMillan v. Parrott, supra; Estate of Zienowicz v. Metropolitan Life Ins. Co., 205 F. Supp. 2d 339 (D.N.J. 2002). *8See, also, Estate of Altobelli v. Intern. Bus. Machines Corp., 77 F.3d 78 (4th Cir. 1996) (Wilkinson, J., dissenting); Fox Valley & Vic. Const. Wkrs. Pension F. v. Brown, supra (Easterbrook, J., dissenting; Ripple, J., dissenting); Keen v. Weaver, 121 S.W.3d 721 (Tex. 2003) (Hecht, J., dissenting). We will call this approach the plan-documents rule.
The plan-documents rule, however, is the minority rule. A majority of courts have concluded that 29 U.S.C. § 1104(a)(1)(D) does not govern the issue, and so one must look to the federal common law. These courts generally hold that when an employee’s spouse waives a beneficiary interest in the employee’s benefit plan under a divorce decree, the waiver is effective despite the employee’s failure to change the beneficiary designation after the divorce. See, e.g., National Auto. Dealers v. Arbeitman, 89 F.3d 496 (8th Cir. 1996); Estate of Altobelli v. Intern. Bus. Machines Corp., supra; Brandon v. Travelers Ins. Co., 18 F.3d 1321 (5th Cir. 1994); Fox Valley & Vic. Const. Wkrs. Pension F. v. Brown, supra (en banc); Keen v. Weaver, supra. Cf. Metropolitan Life Ins. Co. v. Hanslip, 939 F.2d 904 (10th Cir. 1991). We will call this the waiver rule.
(i) Precedential Weight of Federal Court Decisions When Construing Federal Rule
Before determining whether to follow the plan-documents rule or the waiver rule, we need to resolve conflicting statements in our case law on what weight we will give lower federal court decisions when Nebraska courts must construe federal law. Some of our decisions in older cases treat lower federal court decisions as binding precedent. For example, in Anderson v. Wagner, 207 Neb. 87, 296 N.W.2d 455 (1980), we relied on decisions from lower federal courts in interpreting the federal Truth in Lending Act. We stated that “we are obligated to examine any existing federal court cases because, in the administration and interpretation of federal legislative acts, pertinent opinions of the federal courts are binding upon the state courts.” (Emphasis supplied.) 207 Neb. at 91, 296 N.W.2d at 458. See, also, First Data Corp. v. State, 263 Neb. 344, 639 N.W.2d 898 (2002) (stating rule in dicta); Darr v. Long, 210 Neb. 57, 313 N.W.2d 215 (1981); Hadley v. Union P. R. Co., 99 Neb. 349, 156 N.W. 765 (1916).
*9Of course, in cases like this, when federal courts disagree on what is the correct rule, it is impossible for us to apply the rule that federal court decisions are binding. If we treat one group of opinions as binding, we necessarily disregard the other group as nonbinding.
Our decisions in the older cases present a broader problem: They conflict with our more recent cases that have treated lower federal court decisions as persuasive rather than binding. See, In re Application of Lincoln Electric System, 265 Neb. 70, 655 N.W.2d 363 (2003); In re Search Warrant for 3628 V St., 262 Neb. 77, 628 N.W.2d 272 (2001). Accord Whipps Land & Cattle Co. v. Level 3 Communications, 265 Neb. 472, 481, 658 N.W.2d 258, 267 (2003) (“[o]n matters of federal law, the decisions of federal courts are highly persuasive, particularly where federal legislative history and the interpretation of federal statutes are at issue”). For example, in In re Application of Lincoln Electric System, supra, we were required to interpret 47 U.S.C. § 253 (2000) of the federal Telecommunications Act to determine if it preempted a Nebraska statute. After noting that federal courts disagreed on the issue, we stated that “the Supreme Court has not addressed the specific preemption issue before us, and in the absence of an interpretation of § 253(a) by the Court, we are not bound by any circuit court’s interpretation.” 265 Neb. at 79, 655 N.W.2d at 371.
Similarly, in In re Search Warrant for 3628 V St., supra, we were confronted with a split in federal authority over whether the First Amendment guarantees access to a sealed affidavit used to support a search warrant. We rejected the argument that we were bound to follow the position adopted by the Eighth Circuit. In reaching that conclusion, we relied on Justice Thomas’ concurring opinion in Lockhart v. Fretwell, 506 U.S. 364, 113 S. Ct. 838, 122 L. Ed. 2d 180 (1993). He wrote:
The Supremacy Clause demands that state law yield to federal law, but neither federal supremacy nor any other principle of federal law requires that a state court’s interpretation of federal law give way to a (lower) federal court’s interpretation. In our federal system, a state trial court’s interpretation of federal law is no less authoritative than that of the federal court of appeals in whose circuit the trial court is *10located.... An Arkansas trial court is bound by this Court’s (and by the Arkansas Supreme Court’s and Arkansas Court of Appeals’) interpretation of federal law, but if it follows the Eighth Circuit’s interpretation of federal law, it does so only because it chooses to and not because it must.
(Citations omitted.) 506 U.S. at 376.
To the extent that First Data Corp. v. State, supra; Darr v. Long, supra; Anderson v. Wagner, 207 Neb. 87, 296 N.W.2d 455 (1980); Hadley v. Union P. R. Co., supra, and any other case suggest that lower federal court decisions are binding, they are overruled. So, while Nebraska courts must treat U.S. Supreme Court decisions as binding authority, lower federal court decisions are only persuasive authority.
(ii) Adoption of Waiver Rule
Having concluded that we are not required to treat lower federal court decisions as binding precedent, we must now decide whether Nebraska will follow the waiver rule or the plan-documents rule. We determine the waiver rule is the better rule.
Courts are to develop a federal common law of rights and obligations under ERISA-regulated plans. Anderson v. HMO Nebraska, 244 Neb. 237, 505 N.W.2d 700 (1993). But the “authority of courts to develop a ‘federal common law’ under ERISA ... is not the authority to revise the text of the statute.” Mertens v. Hewitt Associates, 508 U.S. 248, 259, 113 S. Ct. 2063, 124 L. Ed. 2d 161 (1993). So, a court may resort to the federal common law to answer a question only when ERISA is silent on the issue. See Mers v. Marriott Intern., 144 F.3d 1014 (7th Cir. 1998).
Courts adopting the minority plan-documents rule have concluded that ERISA is not silent on whether a non-QDRO divorce decree can waive a beneficiary interest in an ERISAgoverned benefit plan. As noted, these courts rely on 29 U.S.C. 1104(a)(1)(D), which requires that fiduciaries, including plan administrators, must discharge their duties “in accordance with the documents and instruments governing the plan.” They reason that determining who is entitled to the death benefits under an ERISA-governed plan is one of the plan administrator’s duties and that therefore, plan administrators should examine the plan *11documents rather than turning to rules supplied by the federal common law.
We, however, are not persuaded by the statutory construction used by the court’s adopting the plan-documents rule. Instead, we agree with the majority of courts that have recognized that 29 U.S.C. § 1104(a)(1)(D) only attempts to set out a plan administrator’s duties. It is, therefore, “a very thin reed” upon which to conclude that ERISA expressly establishes a methodology for determining the beneficiary of an ERISA-governed benefits plan. Manning v. Hayes, 212 F.3d 866, 872 (5th Cir. 2000).
Nor are we persuaded by the dissent’s argument that Egelhoff v. Egelhoff, 532 U.S. 141, 121 S. Ct. 1322, 149 L. Ed. 2d 264 (2001), undermines the waiver rule. In Egelhoff, the court held that ERISA preempted a Washington statute that provided that a spouse’s designation of a beneficiary of a nonprobate asset is revoked automatically upon divorce. But it did not answer the issue presented in this case: whether under federal law an extraneous divorce decree can waive a beneficiary interest in an ERISA-governed benefits plan. In fact, by our count, every court to consider this issue has rejected the argument that Egelhoff undermines the waiver rule. See, Guardian Life Ins. Co. of America v. Finch, 395 F.3d 238 (5th Cir. 2004); Keen v. Weaver, 121 S.W.3d 721 (Tex. 2003); MacInnes v. MacInnes, 260 Mich. App. 280, 677 N.W.2d 889 (2004).
Because ERISA does not expressly control the issue whether an extraneous divorce decree can waive a beneficiary interest in an ERISA-governed benefits plan, the issue is controlled by the federal common law. In developing a federal common law to govern ERISA issues, it is appropriate to look to both the statute itself as well as analogous state law. See, Manning v. Hayes, supra; Fox Valley & Vic. Const. Wkrs. Pension F. v. Brown, 897 F. 2d 275 (7th Cir. 1990).
Under Nebraska law, the general rule is that divorce, per se, does not affect a beneficiary designation in a non-ERISA life insurance policy, IRA, annuity, or similar financial investment. Pinkard v. Confederation Life Ins. Co., 264 Neb. 312, 647 N.W.2d 85 (2002). But a spouse may waive such a beneficiary interest in a divorce decree. See id. For example, in Pinkard, we held that when a former wife waived her beneficiary interest in an annuity *12by entering into a property settlement agreement, the waiver was effective even though her former husband had not changed the beneficiary designation after the divorce. In determining whether a divorce decree waives a beneficiary interest,
the inquiry should be upon the language of the dissolution decree and any agreement which sets forth the intentions of the parties concerning property rights. If the dissolution decree and any property settlement agreement incorporated therein manifest the parties’ intent to relinquish all property rights, then such agreement should be given that effect.
Pinkard v. Confederation Life Ins. Co., 264 Neb. at 318, 647 N.W.2d at 89.
The rule we adopted in Pinkard for addressing beneficiary interests in non-ERISA financial investments and insurance policies is consistent with the federal common law developed by courts following the waiver rule. See, e.g., Melton v. Melton, 324 F.3d 941, 945-46 (7th Cir. 2003) (holding test is “whether a reasonable person would have understood that she was waiving her interest in the proceeds or benefits in question than with any magic language contained in the waiver itself”); Manning v. Hayes, 212 F.3d 866, 871 (5th Cir. 2000) (holding waiver is effective if “explicit, voluntary and made in good faith”). We see no problem then in using the same standard we announced in Pinkard to determine whether a person waived a beneficiary interest in an ERISA-governed benefit plan.
So, the issue in this case is whether the dissolution decree and any property settlement agreement incorporated therein manifested Melissa’s intent to relinquish all property rights in the pension death benefit. If so, the agreement will be given effect.
Melissa and William’s divorce decree provided:
Each of the parties is awarded the ownership of the . . . personal property of every kind and description now in each party’s possession, including bank accounts, automobiles, 401K plans, retirement plans, insurance policies, and other intangible property now possessed by each or owned by each in their separate names ....
. . . All property and money received and retained by the parties pursuant hereto, except as specifically provided to *13the contrary, shall be the separate property of the respective parties, free and clear of any right, interest or claim of the other party and each party shall have the right to deal with and dispose of his or her separate property, both real and personal as fully and effectively as if the parties had never been married ....
Thus, the decree expressly stated not only that the retirement plan belonged to William, but that he would take it “free and clear of any right, interest or claim” of Melissa. We agree with the trial court that this unambiguously shows that Melissa, by entering into the divorce decree, intended to waive whatever interest she had in William’s retirement plan, including her beneficiary interest in the plan’s death benefit. Because there are no disputed fact questions regarding Melissa’s intent, the court correctly entered summary judgment for the Estate.
V. CONCLUSION
We hold that under the federal common law, a party waives his or her beneficiary interest in an ERISA-governed benefits plan by entering into a divorce decree if the decree and any property settlement agreement incorporated therein manifest the parties’ intent to relinquish all property rights in the plan. Because it is undisputed that the divorce decree shows that Melissa intended to waive her beneficiary interest in the death benefit of the Plan, the Estate was entitled to summary judgment.
