delivered the opinion of the Court.
This case, brought under § 502(a) of the Employee Retirement Income Security Act of 1974 (ERISA), 88 Stat. 891, as amended, 29 U. S. C. § 1132(a), concerns ERISA’s preemption and saving clauses. The preemption clause, § 514(a), 29 U. S. C. § 1144(a), broadly states that ERISA provisions “shall supersede... State laws” to the extent that those laws “relate to any employee benefit plan.” The saving clause, § 514(b)(2)(A), 29 U. S. C. § 1144(b)(2)(A), phrased with similar breadth, exempts from preemption “any law of any State which regulates insurance.” The key words “regulates insurance” in § 514(b)(2)(A), and “relate to” in § 514(a), once again require interpretation, for their meaning is not “plain”; sensible construction of ERISA, our decisions indicate, requires that we measure these words in context. See
Pilot Life Ins. Co.
v.
Dedeaux,
The context here is a suit to recover disability benefits under an ERISA-governed insurance policy issued by defendant-petitioner UNUM Life Insurance Company of America (UNUM). Plaintiff-respondent John E. Ward submitted his proof of claim to UNUM outside the time limit set in the policy, and UNUM therefore denied Ward’s claim.
and reversing the District Court’s summary judgment for UNUM, the Court of Appeals for the Ninth Circuit relied on decisional law in California, the State in which Ward worked and in which his employer operated. The Ninth Circuit’s judgment rested on two grounds. That
*364
court relied first on California’s “notice-prejudice” rule, under which an insurer cannot avoid liability although the proof of claim is untimely, unless the insurer shows it was prejudiced by the delay. The notice-prejudice rule is saved from preemption, the Court of Appeals held, because it is “law ... which regulates insurance.” See
Ward
v.
Management Analysis Co. Employee Disability Benefit Plan,
The Court of Appeals announced a further reversing the District Court’s judgment for UNUM, one that would come into play if the insurer proved prejudice due to the delayed notice. Under California’s decisions, the Ninth Circuit said, the employer could be deemed an agent of the insurer in administering group insurance policies. Ward’s employer knew of his disability within the time the policy allowed for proof of claim. The Ninth Circuit held that the generally applicable agency law reflected in the California eases does not “relate to” employee benefit plans, and therefore is not preempted. See id., at 1281-1283, 1287-1288.
We granted the Court of Appeals’ first disposition, and reverse the second. California’s notice-prejudice rule, we agree, is a “law ... which regulates insurance,” and is therefore saved from preemption by ERISA. California’s agency law, we further hold, does “relate to” employee benefit plans, and therefore does not occupy ground outside ERISA’s preemption clause.
I
UNUM issued a long-term group disability policy to Management Analysis Company (MAC) as an insured welfare benefit plan governed by ERISA, effective November 1, 1983. The policy provides that proofs of claim must be furnished to UNUM, at the latest, one year and 180 days after the onset of disability.
Ward was employed by MAC from 1983 Throughout this period, premiums for the disability policy
*365
were deducted from Ward’s paycheck. Under the admitted facts of the case, Ward became permanently disabled with severe leg pain on the date of his resignation, May 5, 1992. See
Ward’s condition was diagnosed as diabetic neuropathy in December 1992. In late February or early March 1993, he qualified for state disability benefits and thereupon informed MAC of his disability and inquired about continuing health insurance benefits. In July 1993, Ward received a determination of eligibility for Social Security disability benefits and forwarded a copy of this determination to MAC’S human resources division. See id., at 1279. In April 1994, Ward discovered among his papers a booklet describing the long-term disability plan and asked MAG whether the plan covered his condition. When MAC told him he was covered, Ward completed an application for benefits and forwarded it to MAC. In turn, and after filling in the employer information section, MAC forwarded the application to UNUM. UNUM received proof of Ward’s claim on April 11, 1994. See ibid. This notice was late under the terms of the policy, which required submission of proof of claim by November 5, 1993. See id., at 1280. By letter dated April 13, 1994, UNUM advised Ward that his claim was denied as untimely. See id., at 1279.
In September 1994, Ward filed suit against the MAC plan under §502 of ERISA, 29 U. S. C. § 1132, to recover the disability benefits provided by the plan. UNUM appeared as a defendant and answered on behalf of itself and the plan. See
The Court of tifying two grounds on which Ward might prevail. First, following the Ninth Circuit’s recent decision in
Cisneros
v.
UNUM Life Ins. Co.,
HH
California’s notice-prejudice rule prescribes:
“[A] defense based on an insured’s failure to give timely notice [of a claim] requires the insurer to prove that it suffered substantial prejudice. Prejudice is not pre *367 sumed from delayed notice alone. The insurer must show actual prejudice, not the mere possibility of prejudice.” Shell Oil Co. v. Winterthur Swiss Ins. Co.,12 Cal. App. 4th 715 , 760-761,15 Cal. Rptr. 2d 815 , 845 (1st Dist. 1993) (citations omitted).
The parties agree that the notice-prejudice rule falls under ERISA’s preemption clause, § 514(a), as a state law that “relate[s] to” an employee benefit plan. 1 Their dispute hinges on this question: Does the rule “regulat[e] insurance” and thus escape preemption under the saving clause, § 514(b)(2)(A). 2
Our precedent provides a framework for resolving whether a state law “regulates insurance” within the meaning of the saving clause. First, we ask whether, from a “common-sense view of the matter,” the contested prescription regulates insurance.
Metropolitan Life Ins. Co.
v.
Massachusetts,
A
The Ninth Circuit concluded that California’s notice-prejudice rule “regulates insurance” as a matter of common sense. See
Cisneros,
134 E 3d, at 945. We do not normally disturb an appeals court’s judgment on an issue so heavily dependent on analysis of state law, see
Runyon
v.
McCrary,
UNUM and its urge cuit’s common-sense conclusion that the notice-prejudice rule is merely an industry-specific application of the general principle that “disproportionate forfeiture should be avoided in the enforcement of contracts.” See Brief for American Council of Life Insurance et al. as
Amici Curiae
13; Brief for Association of California Life and Health Insurance Companies as
Amicus Curiae
5 (“[Njotice-prejudice is merely a branch of the broad doctrine of harmless error.”). Given the tenet from which the notice-prejudice rule springs, UNUM
*369
maintains, the rule resembles the Mississippi law at issue in
Pilot Life;
under that law, punitive damages could be sought for “bad faith” in denying claims without any reasonably arguable basis for the refusal to pay. See
We do not find it fair to bracket California’s notice-prejudice rule for insurance contracts with Mississippi’s broad gauged “bad faith” claim for relief. Insurance policies like UNUM’s frame timely notice provisions as conditions precedent to be satisfied by the insured before an insurer’s contractual obligation arises. See 1 B. Witkin, Summary of California Law, Contracts § 726, p. 657 (9th ed. 1987);
Zurn Engineers
v.
Eagle Star Ins. Co.,
It is no doubt true that out the maxim that “law abhors a forfeiture”
3
and that the
*371
notice-prejudice rule is an application of that maxim. But it is an application of a special order, a rule mandatory for insurance contracts, not a principle a court may pliably employ when the circumstances so warrant. Tellingly, UNUM has identified no California authority outside the insurance-specific notice-prejudice context indicating that as a matter of law, failure to abide by a contractual time condition does not work a forfeiture absent prejudice. Outside the notice-prejudice context, the burden of justifying a departure from a contract’s written terms generally rests with the party seeking the departure. See,
e. g., American Bankers Mortgage Corp.
v.
Federal Home Loan Mortgage Corp.,
*372
California’s insistence that insurers show prejudice before they may deny coverage because of late notice is grounded in policy concerns specific to the insurance industry See Brief for Council of State Governments et al. as
Amici Curiae
10-14. That grounding is key to our decision. Announcing the notice-prejudice rule in
Campbell
v.
Allstate Ins. Co.,
In sum, the Ninth Circuit properly concluded that notice-prejudice is a rule of law governing the insurance relationship distinctively. We reject UNUM’s contention that the rule merely restates a general principle disfavoring forfeitures and conclude instead that notice-prejudice, as a matter of common sense, regulates insurance.

We next consider the criteria used to determine whether a state law regulates the “business of insurance” within the meaning of the McCarran-Ferguson Act. Preliminarily, we reject UNUM’s assertion that a state regulation must satisfy all three McCarran-Ferguson factors in order to “regulate insurance” under ERISA’s saving clause. Our precedent is more supple than UNUM conceives it to be. We have indicated that the McCarran-Ferguson factors are “considerations [to be] weighed” in determining whether a state law regulates insurance,
Pilot Life,
The first McCarran-Ferguson factor asks whether the at issue “has the effect of transferring or spreading a policyholder's risk.”
Metropolitan Life,
Meeting as “an integral part of the policy relationship between the insurer and the insured.”
Metropolitan Life,
The third McCarran-Ferguson factor — which asks whether the rule is limited to entities within the insurance industry— is also well met. As earlier explained, see
supra,
at 368-373, California’s notice-prejudice rule focuses on the insurance industry. The rule “does not merely have an impact on the insurance industry; it is aimed at it.”
FMC Corp.
v.
Holliday,
HH
UNUM and its amici assert that even if the notice-prejudice rule is saved under 29 U. S. C. § 1144(b)(2)(A), it is nonetheless preempted because it conflicts with substantive provisions of ERISA in three ways. UNUM first contends that the notice-prejudice rule, by altering the notice provisions of the insurance contract, conflicts with ERISA’s requirement that plan fiduciaries act “in accordance with the documents and instruments governing the plan.” § 1104(a)(1)(D). According to UNUM, § 1104(a)(1)(D) preempts any state law contrary to a written plan term. See Brief for Petitioner 32-33; Tr. of Oral Arg. 8.
UNUM’s “contra plan term” argument overlooks controlling precedent and makes scant sense. We have repeatedly held that state laws mandating insurance contract terms are saved from preemption under § 1144(b)(2)(A). See
Metropolitan Life,
UNUM next vision, § 502(a), 29 U. S. C. § 1132(a), preempts any action for plan benefits brought under state rules such as notice-prejudice. Whatever the merits of UNUM’s view of § 502(a)’s preemptive force, 7 the issue is not implicated here. *377 Ward sued under § 502(a)(1)(B) “to recover benefits due . . . under the terms of his plan.” The notice-prejudice rule supplied the relevant rule of decision for this § 502(a) suit. The case therefore does not raise the question whether § 502(a) provides the sole launching ground for an ERISA enforcement action.
Finally, we reject UNUM’s suggestion that the notice-prejudice rule conflicts with §503 of ERISA, 29 U. S. C. § 1133, which requires plans to provide notice and the opportunity for review of denied claims, or with Department of Labor regulations providing that “[a] claim is filed when the requirements of a reasonable claim filing procedure ... have been met,” 29 CFR §2560.503-1(d) (1998). By allowing a longer period to file than the minimum filing terms mandated by federal law, the notice-prejudice rule complements rather than contradicts ERISA and the regulations. See Brief for United States as Amicus Curiae 19, n. 9.
IV
Ward successfully maintained in the Ninth Circuit that MAG had timely notice of his disability and that his notice to MAG could be found to have served as notice to UNUM on the theory that MAC, as administrator of the group policy, acted as UNUM’s agent. The policy itself provides otherwise:
“For all purposes of this policy, the policyholder [MAC] acts on its own behalf or as agent of the employee. Under no circumstances will the policyholder be deemed the agent of the Company [UNUM] without a written authorization.” App. to Pet. for Cert. 44a.
*378
California law rendered that policy provision ineffective, the Ninth Circuit appeared to conclude, because under the rule stated in
Elfstrom
v.
New York Life Ins. Co.,
Ward does not argue in this Court as comprehended by the Ninth Circuit, is a law that “regulates insurance.” See Brief for Respondent 35 (the Ninth Circuit applied “general principles of agency law,” not a rule determining when “employers who administer insured plans are agents of the insurer as a
matter of law”).
Indeed, it is difficult to tell from the Court of Appeals opinion precisely what rule or principle that court derived from
Elfstrom.
See Brief for Respondent 35 (“[T]he court below did not actually apply the
Elfstrom
rule in this case.”);
In this determination, the Ninth Circuit was The Court of Appeals stated, without elaboration, that
Elf-strom
does not dictate “the manner in which the plan will be administered,” and therefore is consistent with this Court’s ERISA preemption precedent.
Ibid.;
see
New York State Conference of Blue Cross & Blue Shield Plans
v.
Travelers Ins. Co.,
As persuasively urged by the United States in its amicus curiae brief, deeming the policyholder-employer the agent of the insurer would have a marked effect on plan administration. It would “fore[e] the employer, as plan administrator, to assume a role, with attendant legal duties and consequences, that it has not undertaken voluntarily”; it would affect “not merely the plan’s bookkeeping obligations regarding to whom benefits checks must be sent, but [would] also regulat[e] the basic services that a plan may or must provide to its participants and beneficiaries.” Brief 27. Satisfied that the Elfstrom rule “relate[s] to” ERISA plans, we reject the Ninth Circuit’s contrary determination.
* * *
For the reasons stated, the judgment of the Court of Appeals is affirmed in part and reversed in part, and the case is remanded for further proceedings consistent with this opinion.
It is so ordered.
Notes
Common-law rules developed by decisions of state courts are “State law” under ERISA. See 29 U. S. C. § 1144(c)(1) (“The term ‘State law' includes all laws, decisions, rules, regulations, or other State action having the effect of law.”).
State laws that purport to regulate insurance by “deemfingF a plan to be an insurance company are outside the saving clause and remain subject to preemption. See § 1144(b)(2)(B). Self-insured ERISA plans, therefore, are generally sheltered from state insurance regulation. See
Metropolitan Life Ins. Co.
v.
Massachusetts,
UNUM cites a handful of California cases of this genre. They do not cast doubt on our disposition. In
Conservatorship of Rand,
The older decisions on which UNUM relies are no more instructive. The contract at issue in
Ballard
v.
MacCallum,
These decisions support the uncontested propositions that the law disfavors forfeitures and that in case-specific circumstances California courts will excuse the breach of a time or notice provision in order to avoid an inequitable forfeiture. None of the decisions even remotely suggests that failures to comply with contractual notice periods are excused as a matter of law absent prejudice; none, therefore, suggests that the notice-prejudice rule is merely a routine application of a general antiforfeiture principle. 4
§229 of the Restatement (Second) of Contracts (1979), and urges that the notice-prejudice rule fits within its compass. Section 229 provides that “[t]o the extent that the non-occurrence of a condition would cause disproportionate forfeiture, a court may excuse the nonoccurrence of that condition unless its occurrence was a material part of the agreed exchange.” The notice-prejudice rule, however, is mandatory rather than permissive; it requires California courts to excuse a failure to *372 provide timely notice whenever the insurer cannot carry the burden of showing actual prejudice, and it allows no argument over the materiality of the time prescription.
We reject UNUM’s suggestion that because the notice-prejudice rule regulates only the administration of insurance policies, not their substantive terms, it cannot be an integral part of the policy relationship. See Metropolitan Life, 471 U. S., at 728, n. 2 (including laws regulating claims practices and requiring grace periods in catalog of state laws that regulate insurance).
We recognize that applying the States’ varying insurance regulations creates disuniformities for “national plans that enter into local markets to purchase insurance.”
Metropolitan Life,
We discussed this issue in
Pilot Life Ins. Co.
v.
Dedeaux,
(1987). That ease concerned Mississippi common law creating a cause of action for bad-faith breach of contract, law not specifically directed to the insurance industry and therefore not saved from ERISA preemption. In that context, the Solicitor General, for the United States as
amicus curiae-,
urged the exclusivity of § 502(a), ERISA’s civil enforcement provision, and observed that § 502(a) was modeled on the exclusive remedy provided by §301 of the Labor Management Relations Act, 1947 (LMRA), 29 U. S. C. §185. The Court agreed with the Solicitor General’s submission.
In the instant case, the cus curiae, has endeavored to qualify the argument advanced in Pilot Life. See Brief20-25. Noting that “LMRA Section 301 does not contain any statutory exception analogous to ERISA’s insurance savings provision,” the Solicitor General now maintains that the discussion of § 502(a) in Pilot Life “does not in itself require that a state law that ‘regulates insurance,’ and so comes within the terms of the savings clause, is nevertheless preempted if it provides a state-law cause of action or remedy.” Brief 25; see also id., at 23 (“[T]he insurance savings clause, on its face, *377 saves state law conferring causes of action or affecting remedies that regulate insurance, just as it does state mandated-benefits laws.”)* We need not address the Solicitor General’s current argument, for Ward has sued under § 502(a)(1)(B) for benefits due, and seeks only the application of saved state insurance law as a relevant rule of decision in- his § 502(a) action.
