HANDLER, J.

In this case, as in the companion case of Hunter v. Greenwood Trust Co., 143 N.J. 97 , 668 A.2d 1067, (1995) rev'g

272 N.J. Super. 526, 640 A.2d 855 (1994), also decided today, New Jersey credit-card customers contend that New Jersey's usury laws prohibit banks that issue those cards from charging late-payment fees to New Jersey customers.

The issues before us are more specifically framed by the claims and defenses of the respective parties. Plaintiff, as a named party in a class-action suit, challenges the legality of the late-payment fees that are charged to New Jersey holders of defendant Citibank (South Dakota) credit cards. Plaintiff argues that New Jersey's Retail Installment Sales Act of 1960, N.J.S.A. 17:16C-50, -54 (RISA), forbids national banks that issue credit-cards to New Jersey consumers from charging late-payment fees. Plaintiff also argues that defendant's failure to disclose in its cardmember agreements and advertising that late-payment fees are prohibited by New Jersey law violates New Jersey's Consumer Fraud Act (CFA), N.J.S.A. 56:8-2, -19. Finally, plaintiff contends that the imposition of late-payment fees constitutes a common-law breach of contract and conversion.

Defendant relies on section 85 of the National Bank Act (NBA), which provides that a national bank may charge borrowers "interest at a rate allowed by the laws of the State . . . where the bank is located." 12 U.S.C.A. § 85. Citibank is a national bank chartered in South Dakota, and South Dakota includes late-payment fees in its statutory definition of interest. 272 N.J. Super. at 435, 438, 640 A.2d 325 (1994). Citibank, therefore, contends that plaintiff's RISA claim, as well as plaintiff's other claims, conflict with, and are preempted by, section 85. See id. at 439, 640 A.2d 325. Thus, Citibank argues it is free to charge late-payment fees in New Jersey.

Following the commencement of this action, the Law Division granted the bank's motion to dismiss the complaint with prejudice. The Appellate Division affirmed. 272 N.J. Super. 435, 640 A.2d 325 (1994). We granted plaintiff's petition for certification, 138 N.J. 270, 649 A.2d 1289 (1994), and now reverse the dismissal of plaintiff's claims.

We determine that the understanding of "interest" as expressed and authorized in the NBA does not include distinctive and contingent loan terms or charges, such as late fees, that are unrelated to interest rates. We hold that late-payment fees are not "interest" within the intendment and purposes of the applicable federal statute. Rather, "interest at a rate allowed by the laws of the State . . . where the bank is located" refers only to the periodic percentage rate charged on outstanding balances. Therefore, plaintiff's state-law defenses to the bank's charges do not conflict with federal law, are not preempted, and the late-payment fees are illegal under New Jersey law.

I

Since the early years of the Republic, the states have generally resisted the development of national banks and favored their own state-chartered banks through regulatory legislation. William Oscar Scroggs, A Century of Banking Progress 50-51 (1924); John J. Knox, A History of Banking in the U.S. 12 (2d ed. 1969). The Supreme Court has, since M'Culloch v. Maryland, 17 U.S. (4 Wheat.) 316, 4 L.Ed. 579 (1819), generally limited federal statutory involvement by construing preemption narrowly and giving relatively free rein to state usury law regulations. See Anderson Nat'l Bank v. Luckett, 321 U.S. 233, 64 S.Ct. 599, 88 L.Ed. 692 (1944); McClellan v. Chipman, 164 U.S. 347, 17 S.Ct. 85, 41 L.Ed. 461 (1896).

This Court, in considering preemption claims, must be cautioned by the longstanding presumption that "Congress did not intend to displace state law." Maryland v. Louisiana, 451 U.S. 725, 746, 101 S.Ct. 2114, 2129, 68 L.Ed.2d 576, 595 (1981), and that it should not unnecessarily disturb "the federal-state balance." United States v. Bass, 404 U.S. 336, 349, 92 S.Ct. 515, 523, 30 L.Ed.2d 488, 497 (1971). Indeed, greater restraint ought apply to preemption of spheres traditionally occupied by the states. Where the field that Congress is said to have preempted has been traditionally occupied by the states, "we start with the assumption that the historic police powers of the States were not to be superseded by the Federal Act unless there was the clear and manifest purpose of Congress." Rice v. Santa Fe Elevator Corp., 331 U.S. 218, 230, 67 S.Ct. 1146, 1152, 91 L.Ed. 1447 (1947).

"It is well settled that state usury law restrictions on lending practices are so extensive and historically rooted as to form part of the consumer protection terrain `traditionally occupied' by the states." Greenwood Trust Co. v. Massachusetts, 776 F. Supp. 21, 27-28 (D.Mass. 1991), rev'd, 971 F.2d 818 (1st Cir. 1992), cert. denied, 506 U.S. 1052, 113 S.Ct. 974, 122 L.Ed.2d 129 (1993) (citing Lewis v. BT Inv. Managers, Inc., 447 U.S. 27, 38, 100 S.Ct. 2009, 2016, 64 L.Ed.2d 702, 713 (1980) ("We readily accept the submission that, both as a matter of history and as a matter of present commercial reality, banking and related financial activities are of profound local concern")); Smiley v. Citibank (South Dakota), N.A., 11 Cal.4th 138, 44 Cal.Rptr.2d 441, 465-66, 900 P.2d 690, 714-15 (1995) (Arabian, J., dissenting) (same); id. at 467-68, 900 P.2d at 716-17 (George, J., dissenting) (same). Accordingly, "[b]ecause consumer protection law is a field traditionally regulated by the states, compelling evidence of an intention to preempt is required in this area." General Motors Corp. v. Abrams, 897 F.2d 34, 41-42 (2d Cir. 1990) (upholding New York's "Lemon Law" against a claim that a Federal Trade Commission consent decree preempted major elements of the local law). Congress' failure to include an express preemption clause in section 85 necessitates a careful examination of whether the NBA conflicts with RISA's prohibition of late-payment fees.

Section 85 provides in pertinent part:

Any [national bank] association may take, receive, reserve, and charge on any loan or discount made, or upon any notes, bills of exchange, or other evidence of debt, interest at a rate allowed by the laws of the State, Territory or District where the bank is located, or at a rate of 1 per centum in excess of the discount rate on ninety-day commercial paper in effect at the Federal reserve bank in the Federal reserve district where the bank is located, whichever may be the greater . . .

[ 12 U.S.C.A. § 85 (emphasis added).]

On its face, section 85 immunizes national banks that lend money beyond their home-state's borders from local usury laws that might give local banks a competitive advantage. It also protects national banks during periods of inflation by overriding even the home-state's usury laws and permitting national banks to charge interest at a rate tied to the federal discount rate. E.g. Tiffany v. National Bank, 85 U.S. (18 Wall) 409, 412-13, 21 L.Ed. 862, 863-64 (1874) (holding that Congress, by enacting NBA, intended to protect national banks from hostile state usury laws); Roper v. Consurve, Inc., 578 F.2d 1106 (5th Cir. 1978), aff'd sub nom., Deposit Guaranty Nat'l Bank v. Roper, 445 U.S. 326, 100 S.Ct. 1166, 63 L.Ed.2d 427 (1980) (holding section 85 was designed by Congress to mandate parity between national banks and local lenders). However, neither the plain meaning of the terms "rate" and "interest" in section 85, nor the legislative history of that provision indicates that these terms carry the expansive meaning inferred by defendant. See Smiley, supra, 44 Cal.Rptr.2d at 469 , 900 P.2d at 718 (George, J., dissenting).

Since 1874, the Supreme Court has interpreted section 85 as entitling a national bank to charge the highest interest rate allowed to lenders by the laws of the state in which the bank is located. Tiffany, supra, 85 U.S. at 411-13, 21 L.Ed. at 863-64 ("The only mode of guarding against [state discrimination] was . . . to allow to national associations the rate allowed by the state to natural persons generally, and a higher rate"). Courts have recognized that Tiffany construed section 85 to place national banks in a position of limited advantage over state banks by allowing them to charge interest at the highest rate applicable under state law to lenders generally and not necessarily at a rate applicable to state banks, which might be lower. This ability to "borrow" an interest rate has come to be known as the "most-favored-lender" doctrine. See, e.g., Fisher v. First Nat'l Bank, 548 F.2d 255 (8th Cir. 1977) (recognizing that notwithstanding limitations on interest imposed on state banks by Nebraska law, national bank located in Nebraska could legally charge, with respect to credit-card transactions, rates allowed by Nebraska law to small loan companies).

In Marquette National Bank v. First of Omaha Service Corp., 439 U.S. 299, 99 S.Ct. 540, 58 L.Ed.2d 534 (1978), the Supreme Court relied on the NBA and its most-favored-lender doctrine to allow a national bank chartered in Nebraska to charge its credit-card customers in Minnesota a rate of interest authorized in Nebraska, but prohibited by usury law restrictions in Minnesota. Id. at 313-15, 99 S.Ct. at 548-49, 58 L.Ed.2d at 545-46. The Marquette Court recognized that the "exportation" of interest rates from a national bank's "home state" into a foreign state would "significantly impair the ability of the States to enact effective usury laws," but it found that such impairment "has always been implicit in the structure of the National Bank Act since citizens of one State were free to visit a neighboring State to receive credit at foreign interest rates." Id. at 318, 99 S.Ct. at 550, 58 L.Ed.2d at 548 (citation omitted) (footnote omitted).

The Court, nonetheless, suggested Congressional action would be necessary to check the preemptive effect of the NBA in a time of national bank deregulation, tightened credit availability, and an increasingly nationalized credit-card lending system:

This impairment may in fact be accentuated by the ease with which interstate credit is available by mail through the use of modern credit cards. But the protection of state usury laws is an issue of legislative policy, and any plea to alter § 85 to further that end is better addressed to the wisdom of Congress than to the judgment of this Court.

[ Id. at 318-19, 99 S.Ct. at 550, 58 L.Ed.2d at 548 .]

Marquette does not mandate or encourage an extension of the "most-favored-lender" status to expand the definition of "rates" to include other non-interest rate charges. The national bank's authorized exportation of lending terms in Marquette was limited to numerical percentage-rate interest terms. The Court made no mention of the exportation of other credit-card terms, such as late charges, nor did its reasoning or rationale imply that discrete and specialized charges affixed to credit-card loans could be imposed on customers in other states. See Smiley, supra, 44 Cal. Rptr.2d at 465, 900 P.2d at 714 (Arabian, J., dissenting).

In the years following Marquette, Congress embarked on a mission to deregulate the banking industry. Interest rates soared, and while national banks could charge interest at a rate tied to the federal discount rate, state banks were constrained by local usury laws. See Greenwood Trust, supra, 971 F.2d at 826. Congress sought to rectify that obvious inequity by enacting the Depository Institutions Deregulation and Monetary Control Act of 1980, 12 U.S.C.A. § 1831d (DIDA). Ibid. The language of section 521 of DIDA essentially mirrors that of section 85 of the NBA. Courts and federal agencies have interpreted section 521 as conferring on federally-insured state banks the same insulation from state usury laws that national banks have enjoyed under the NBA. Id. at 826-27 (concluding that Section 521 permits federally-insured state banks to "export" interest rates); VanderWeyst v. First State Bank, 425 N.W.2d 803, 806 (Minn.) (concluding that section 521 gives federally-insured state banks "most favored lender" status), cert. denied, 488 U.S. 943, 109 S.Ct. 369, 102 L.Ed.2d 359 (1988).

The legislative history of DIDA is instructive to our understanding of Congress' general understanding of interest and its intent with respect to the notion of interest contained in the NBA. E.g., Copeland v. MBNA America Bank, N.A., 907 P.2d 87, 93 (1995). Although the NBA was enacted 100 years earlier, the same tensions, namely parity between federal and state lenders and preservation of local usury laws, were present and these conflicting considerations generated substantial concerns surrounding the passage of the earlier banking statute.

The record of Congressional debate and deliberation concerning the enactment of DIDA strongly supports the understanding that preemption of credit-card regulation under DIDA is confined to traditional numerical interest rates. The central unifying purpose of DIDA was to provide for increased access to home mortgage loans. Section 501 of DIDA provided for preemption of state usury limits on mortgage loans in a manner virtually identical to the treatment of other loans (including credit-card agreements) in Title V of the Act, which contains section 521.

The Senate Report of deliberations over section 501 of DIDA restricts preemption and expressly reserves the regulation of "late charges" to the states.

In exempting mortgage loans from state usury limitations, the Committee intends to exempt only those limitations that are included in the annual percentage rate. The Committee does not intend to exempt limitations on prepayment charges, attorney fees, late charges or similar limitations designed to protect borrowers.

[S.Rep. No. 96-368, 96th Cong., 2d Sess. 19, reprinted in 1980 U.S. Code Cong. and Ad.News, Vol. 2, 236, 255.]

Subsequent legislative history links preemption concerns in section 501 both to the consideration of section 521, and to DIDA in its entirety as passed on March 27-28, 1980. Notably, Congress passed section 501 at the same time, and the same title (Title V) of the same act, as section 521.

During the discussion on the Senate floor of the various bills that figured in the development of DIDA, Senators Pryor and Bumpers proposed an amendment, S. 1988, to give state-chartered institutions "competitive equality" with national banks by allowing them to charge interest at one percent above the federal discount rate. 125 Cong.Rec. 30655 (1979). Senator Proxmire, floor manager of the Senate bills under discussion, and chairman of the Senate Banking Committee, understood the proposed amendment to override state usury laws and emphasized that there was "a sharp division and difference of opinion in the Senate." Id.

Separate hearings on the Pryor-Bumpers initiative, S. 1988, 96th Cong. 1st Sess, (1979) were held December 17, 1979, and though it was not reported out of committee, the bill's language was substantially incorporated into House Bill 4986, H.R. 4986, 96th Cong., 1st Sess. (1979), which was, in turn, enacted as DIDA. William M. Burke Alan S. Kaplinsky, Unraveling the New Federal Usury Law, 37 Bus.Law. 1079, 1096-97 and n. 102 (1982).

A fair reading of the legislative history indicates that Congressional concern was focused with particularity on numerical or percentage interest rates. In introducing S. 1988, Senator Pryor noted, "A national bank may charge one percent above the Federal discount rate, notwithstanding any State laws setting an interest-rate ceiling . . . [which] obviously discriminates in the strongest possible way against State banks." 125 Cong.Rec. 30655 (1979). The great bulk of the subsequent committee testimony and discussion indicates that the proposed preemption amendment was limited because, in Senator Pryor's words, it "would merely allow State chartered, federally insured banks . . . to charge the same interest rate as national banks." Id. In fact, there were only two references to wider displacement of state law though expansion of the "most-favored-lender doctrine." Senator Bumpers, co-sponsor of the preemption amendment, confined his remarks to numerical interest rate disparities and remarked pointedly, "I do not think it is particularly healthy to be overriding state law." Id.

Post-DIDA legislative history tends to confirm the conclusion that Congress in 1980 did not intend to bar states from prohibiting late fees by credit-card issuers. In 1981 and in 1983-84 the Senate (but not the House) passed amendments to DIDA which would have expanded preemption of state usury laws, but would have expressly exempted late charges from preemption. Greenwood Trust, supra, 776 F. Supp. at 31 (citing Hearings on S. 730 Before the Senate Committee on Banking, Housing and Urban Affairs, 98th Cong., 1st Sess. (April 12, 1983); Hearings on S. 1720, 1981. The failed S. 730 bill also expressly granted states the right to override preemption.

Thus, the fact that Congress was specifically concerned about effecting a preemption limited to numerical interest rates is significant. If we cannot attribute to legislative initiative of 15 years ago the intent to include discrete, specialized charges within a definition of interest, we cannot ascribe that expansive definition to a legislative initiative that occurred over 100 years earlier. That is especially so when the later statute substantially paralleled the language of the former, and it was passed in an effort to give federally-insured state banks status equal to national banks that had enjoyed a superior status since the enactment of the earlier act. Thus, it would be contrary to common sense to conclude that in enacting the NBA, Congress contemplated an open-ended and expansive concept of interest that was light years from the traditional understanding of a fixed, basic percentage rate applied to an unpaid loan balance. Or that, correlatively, it intended to prohibit states from regulating specific terms and conditions of loans and preventing lenders from charging late-payment fees.

II

Defendant relies on case law from other jurisdictions to support its expansive interpretation of "interest", specifically, Greenwood Trust, supra, 971 F.2d 818 and Tikkanen v. Citibank (South Dakota), N.A., 801 F. Supp. 270 (D.Minn. 1992). We find, however, that the reasoning expressed in the Greenwood Trust line of cases and the authorities cited by the Greenwood Trust court are unpersuasive and do not support the conclusion that Congress intended to include non-interest rate charges in its understanding of interest.

Greenwood Trust held that prior case law supported the notion that federal common law construes interest to encompass a variety of lender-imposed fees and financial requirements that are independent of a numerical percentage rate. 971 F.2d at 829 (citing American Timber Trading Co. v. First Nat'l Bank, 690 F.2d 781, 787-88 (9th Cir. 1982); Fisher v. First Nat'l Bank, 548 F.2d 255, 258-61 (8th Cir. 1977); Panos v. Smith, 116 F.2d 445, 446-46 (6th Cir. 1940); Cronkleton v. Hall, 66 F.2d 384, 387 (8th Cir.), cert. denied, 290 U.S. 685, 54 S.Ct. 121, 78 L.Ed. 590 (1933); Nelson v. Citibank (South Dakota) N.A., 794 F. Supp. 312 , 318 (D.Minn. 1992)). Inimical to the holding in Greenwood Trust, a careful examination of the cases cited does not establish that Congress intended to include late-payment fees within a federal definition of interest under either section 85 or section 521.

Contrary to the Greenwood Trust court's interpretation, American Timber Trading Co., supra, did not hold that a compensating-balance requirement was interest under section 85. Rather, the court held that a compensating-balance requirement reduces the principal amount of a loan for purposes of calculating effective interest. 690 F.2d at 787-88. In addition, Fisher, supra, did not expressly hold that cash-advance fees were interest under section 85. In that case, the plaintiff challenged the periodic interest and cash-advance fees charged by an out-of-state national bank. 548 F.2d at 256. The court applied the most favorable laws covering any class of lenders in the bank's home state, which permitted certain lenders to charge 30% interest on a balance under $300, and held that the charges were not usurious. Id. at 258-61. The court did not even discuss the distinction between periodic interest rates and the flat fees charged.

In Panos, supra, the court did not hold that mortgage taxes and recording fees were interest under section 85. Rather, the court held that such charges, which were deducted from the principal received by the borrower, reduced the principal amount of a loan for purposes of calculating effective interest. 116 F.2d at 446-47.

In Cronkleton, supra, the court did not conclude that a bonus or commission was interest under section 85. The Eighth Circuit's holding (in relevant part) was limited to a modification of the district court's award of damages for usury under the NBA. The court's opinion does not provide a detailed account of the facts. However, it appears that in February 1926, the defendant, a national bank, loaned $55,000 to the plaintiffs. 66 F.2d at 385. The contractual periodic rate of interest was not usurious. Ibid. But, in November 1930, plaintiffs paid to the bank an additional $1,000. Ibid. Although the district court "made no findings as to bonuses paid," the court characterized the additional payment as a bonus or commission. Id. at 386. The court then noted that "in determining the rate `reserved' or `charged' . . . the taking of a `bonus' or `commission' . . . may enter in to render an otherwise lawful rate unlawful and usurious." Id. at 387.

The Greenwood Trust court suggested that Nelson, supra, decided three months earlier, held that late-payment fees were interest under section 85. 971 F.2d at 829. However, Nelson expressly disclaimed that conclusion. 794 F. Supp. at 320 ("the question of whether national banks may export terms other than periodic interest charges goes to the merits of the case; deciding that question on a motion to remand is inappropriate"). The court held only that the defendant's claim that section 85 preempted plaintiffs' state law claims raised a substantial federal question. Id. at 315-16.

The court in Greenwood Trust also cited several cases to support the proposition that section 85 "adopts the entire case law of [a state bank's home] state interpreting the state's limitations on usury; it does not merely incorporate the numerical rate adopted by the state." 971 F.2d at 829 (citing First Nat'l Bank v. Nowlin, 509 F.2d 872, 876 (8th Cir. 1975); accord Roper v. Consurve, Inc., 777 F. Supp. 508 , 510-11 (S.D.Miss. 1990), aff'd, 932 F.2d 965 (5th Cir.) (table), cert. denied, 502 U.S. 861, 112 S.Ct. 181, 116 L.Ed.2d 142 (1991); Daggs v. Phoenix Nat'l Bank, 177 U.S. 549, 555, 20 S.Ct. 732, 735, 44 L.Ed. 882 (1900); Union Nat'l Bank v. Louisville, N.A. C. Ry., 163 U.S. 325, 331, 16 S.Ct. 1039, 1042, 41 L.Ed. 177 (1896); Bartholomew v. Northampton Nat'l Bank, 584 F.2d 1288, 1295 (3d Cir. 1978); McAdoo v. Union Nat'l Bank, 535 F.2d 1050, 1055-58 (8th Cir. 1976); Northway Lanes v. Hackley Union Nat'l Bank Trust Co., 464 F.2d 855, 861-64 (6th Cir. 1972)). Those cases, however, do not demonstrate that Congress intended to incorporate a state definition of interest that would authorize states unilaterally to incorporate non-percentage rate charges into an exportable definition under section 85. Moreover, none of those cases involve a definition of interest for exportation purposes where the definition varied between states.

Nowlin, supra, exemplifies the Greenwood Trust court's misplaced reliance on previous cases construing the NBA. In Nowlin, a national bank in Arkansas loaned money to the plaintiff, who agreed to repay the loan in installments. 509 F.2d at 874. Instead of amortizing the loan over the agreed term, the bank "discounted" the notes by 8%; that is, the bank gave the plaintiff the requested sum, but an additional 8% for every year of the notes' term was immediately added to the outstanding principal amount. Ibid. The plaintiff then had to repay the adjusted principal amount in equal payments over the term. Ibid. Because all interest was calculated up-front based on the initial loan amount, instead of being calculated periodically on a declining principal balance, the national bank achieved an effective yield of nearly 16%. Ibid.

The bank did not dispute that Arkansas considered usurious interest rates over 10%. Id. at 876. Furthermore, the bank did not dispute that a state bank could not "discount" notes in a like manner because Arkansas case law defined interest for purposes of its usury laws as "effective yield." Ibid. However, the bank argued that because it was a national bank, it was subject only to section 85, which defined interest narrowly to include only percentage rates charged, not effective yields. Ibid. Because its 8% discount rate was less than the 10% Arkansas-usury rate, the bank argued that it did not violate the NBA. Ibid.

The court rejected the bank's arguments. After discussing the objectives of section 85, the court held that such a narrow interpretation would be inconsistent with Congress' desire to foster competitive equality between state and national banks. Id. at 880. Thus, the court held, Arkansas' definition of interest was incorporated into section 85. Ibid.

Contrary to the Greenwood Trust Court's conclusion, Nowlin does not offer an expanded definition of the term "rate," but rather shows only that calculation of chargeable interest rates must take "the case law of the state" into account. The state law regarding discounting was given substantial weight because discounting, unlike late-fee charges, directly affects the numerical interest rate by altering the percentage rate over time. It is noteworthy that the Nowlin decision involved the intra-state, not inter-state, application of Arkansas' definition of interest. Thus, it said nothing about exporting that definition to a foreign state where state-usury laws are more restrictive. Moreover, the case should be read as a judicial attempt to protect state usury laws at the expense of the federal most-favored-lender doctrine.

Defendant also refers, as does the dissent, to Smiley v. Citibank, supra, 11 Cal.4th 138, 44 Cal.Rptr.2d 441, 900 P.2d 690 (1995), to support its position that "interest" under section 85 includes late charges. Post at 74, 668 A.2d at 1055. Similar use is made of Copeland v. MBNA America Bank, N.A., supra, 907 P.2d 87 (1995). The majority in Smiley bases that conclusion in large measure on its understanding of historical legal usage. Smiley, supra, 44 Cal.Rptr.2d at 449-51, 900 P.2d at 698-700. See also Copeland, supra, at 91-92 (same). In our view, however, interest in its historical setting is limited to a periodic charge expressed as a percentage of a principal balance due. See discussion, infra, at 60-62, 668 A.2d at 1048-1049. The majority in Smiley also concluded that if interest does not include late charges then a state could discriminate against a national bank to make it unprofitable for it to lend money in that state. Smiley, supra, 44 Cal.Rptr.2d at 451, 900 P.2d at 700. However, a state cannot discriminate against a national bank by permitting state banks to charge late fees or higher late fees while prohibiting a national bank from charging those fees. See discussion, infra at 68-71, 668 A.2d at 1052-1053. See Smiley, supra, 44 Cal. Rptr.2d at 470, 900 P.2d at 719 (George, J., dissenting) (noting that it has been established since the early 1800's that even in the absence of a specific federal statutory prohibition a state may not discriminate against a federal instrumentality either in the enactment or enforcement of state laws). Thus, the most-favored-lender doctrine serves to eliminate discrimination without distorting or extending the meaning of interest to include charges that Congress neither expressly nor implicitly incorporated in the definition of interest.

III

Defendant, as well as the dissent, cites a recently-promulgated proposed interpretive ruling by the Office of the Comptroller of the Currency (OCC), the agency charged with enforcement of the NBA, as evidence that late fees constitute interest for purposes of the NBA. Post at 82, 668 A.2d at 1059. The soundness of this ruling, and its value as authority, are greatly undermined when placed in the context of conflicting OCC rulings.

It is well settled that in general an agency's interpretation of a statute it is charged with enforcing is entitled to substantial deference, Chevron, U.S.A., Inc. v. Natural Resources Defense Council, Inc., 467 U.S. 837, 843-45, 104 S.Ct. 2778, 2781-83, 81 L.Ed.2d 694, 703-04 (1984); EPA v. National Crushed Stone Ass'n, 449 U.S. 64, 83, 101 S.Ct. 295, 307, 66 L.Ed.2d 268, 283 (1980) (citing Udall v. Tallman, 380 U.S. 1, 16, 85 S.Ct. 792, 801, 13 L.Ed.2d 616 (1965)), and must in general be upheld even if that interpretation is not the only permissible one or even the most reasonable. Grocery Town Market, Inc. v. United States, 848 F.2d 392, 396 (3d Cir. 1988). There are, however, exceptions to the general rule.

Far less than the usual amount of deference to an agency interpretation is appropriate when that agency has failed to adopt a consistent interpretation in administering the statute in question. INS v. Cardoza-Fonseca, 480 U.S. 421, 446 n. 30, 107 S.Ct. 1207, 1221 n. 30, 94 L.Ed.2d 434, 457 n. 30 (1987) (citing Watt v. Alaska, 451 U.S. 259, 273, 101 S.Ct. 1673, 1681, 68 L.Ed.2d 80 (1981); General Elec. Co. v. Gilbert, 429 U.S. 125, 143, 97 S.Ct. 401, 411-12, 50 L.Ed.2d 343 (1976)).

"It is emphatically the province and duty of the judicial department to say what the law is." Marbury v. Madison, 5 U.S. (1 Cranch) 137, 177, 2 L.Ed. 60 (1803). Statutory construction is ultimately a judicial function. See, e.g., SEC v. Sloan, 436 U.S. 103, 118, 98 S.Ct. 1702, 1712, 56 L.Ed.2d 148, 161 (1978); Federal Maritime Comm. v. Seatrain Lines, Inc., 411 U.S. 726, 745-46, 93 S.Ct. 1773, 1784-85, 36 L.Ed.2d 620, 633-34 (1973). Indeed, "one of the Judiciary's characteristic roles is to interpret statutes." Japan Whaling Ass'n v. American Cetacean Soc'y, 478 U.S. 221, 230, 106 S.Ct. 2860, 2866, 92 L.Ed.2d 166, 179 (1986). Accordingly, the Supreme Court in Chevron, supra, did not state that silence or ambiguity in a statute automatically requires a court to delegate its entire interpretive responsibility to an agency, especially when an agency's interpretation is contrary to the purpose of the statute or inconsistent. See West v. Bowen, 879 F.2d 1122, 1138 (3d Cir. 1989) (Mansmann, J., concurring and dissenting).

Courts have found consistency or lack thereof in an agency interpretation to be crucial in determining the degree of deference to be afforded that interpretation. See, e.g., INS v. Cardoza-Fonseca, supra (rejecting deference to Board of Immigration Appeals due to years of inconsistent positions); Director, Office of Workers' Compensation Programs v. Mangifest, 826 F.2d 1318, 1319-20 (3d Cir. 1987) (finding "ambiguities and inconsistencies in the Director's interpretation of . . . regulations . . . sufficiently great to preclude deference"); Revak v. National Mines Corp., 808 F.2d 996, 1002 (3d Cir. 1986) (rejecting deference arguments due to inconsistent agency interpretation of statute); Disabled in Action v. Sykes, 833 F.2d 1113, 1117-19 (3d Cir. 1987), cert. denied, 485 U.S. 989, 108 S.Ct. 1293, 99 L.Ed.2d 503 (1988). There is a great difference between flexibility and vacillation. Accordingly, judicial deference to administrative rulings should be cast on a sliding scale whereby the usual respect for agency determination diminishes as apparent inconsistencies surmount. West, supra, 879 F.2d at 1134 (Mansmann, J., dissenting and concurring).

The federal administrative understanding of the meaning of "interest" has wavered. Cf. Copeland, supra, 907 P.2d 87, 92 (asserting that "[t]he OCC consistently has taken the position that late payment fees are interest" under both section 85 of the NBA and section 521 of the DIDA) (emphasis added). An examination of OCC interpretive letters reveals significant inconsistent administrative treatment of interest with respect to the NBA. As early as 1964, the OCC, responding to an inquiry to define interest under the NBA, stated that "late payment fees . . . would not properly be characterized as interest." See Letter by James J. Saxon, Comptroller of the Currency (June 25, 1964), Brief of Petitioner-Defendant at Ex C. (No. 38,817). Then, in 1986, the OCC was asked specifically whether late fees were considered interest that could be exported under section 85. Letter by Charles F. Byrd, Assistant Director, Legal Advisory Service (May 5, 1986), 1986 WL 143937 (O.C.C.). The agency opined that section 85 looks to state law to determine the maximum permissible interest rate, but that federal law determines which charges are "material" to the rate determination. Id. at [*]1. Because courts had not determined whether late fees were material, the OCC refused to provide the answer. Ibid.

In 1988, however, the OCC issued Interpretive Letter No. 452, which addressed whether various fees charged by an out-of-state national bank to its credit cardholder in Iowa were material to the determination of the interest rate under Section 85. Letter by Robert B. Serino, Deputy Chief Counsel, Office of the Comptroller of Currency [1988-1989 Transfer Binder] Fed. Banking L.Rep. (CCH) ¶ 85,676 at 78,063 (Aug. 11, 1988). The agency concluded that whether particular fees are material to the interest rate determination under section 85 depends on the laws of a national bank's home state. Id. at 78,065-66 (citing Interpretive Ruling 7.7310, 12 C.F.R. § 7.7310(a)).

The OCC recently has affirmed that position. See Letter by Peter Liebsman, Assistant Director, Bank Operations and Asset Division (February 26, 1993), 1993 WL 501557 at [*]2 (the "1993 OCC Letter"). However, because the State failed to define "materiality", the 1993 OCC Letter stated that "characteristics of either the loan or the borrower . . . [that are] an integral part of a bank's decision to establish the rate of interest that will be charged" typically are material. Id. at [*]3. Notably, the OCC opined that charges such as "late fees, nonsufficient check charges, cash advance fees and attorney fees appear not to determine the numerical rate of interest to be charged." Id. at [*]4. Because such fees have only an "indirect effect on interest rates in that they may affect the ultimate return on loan proceeds," the agency suggested that absent their inclusion in the home-state's definition of interest, they would not be material, and thus, would not be exportable. See ibid.

The conflicting interpretations, coupled with the logic expressed in the "materiality" standard, convince us that this Court should not forsake its own considered reasoning by relying on an equivocation. It is the responsibility of Congress to depart from the traditional understanding of interest and to express an intent to include non-numerical interest rates in its definition of "interest" under the NBA.

IV

New Jersey's banking statutes also reflect the basic understanding that the notion of interest was conceived and continues to be defined as specific percentage rates, rather than discrete charges, such as late fees, which are not directly related to borrowing money. N.J.S.A. 17:13A, which governs installment loan rate advertising, defines interest as follows:

every charge paid to the lender or contracted for by the lender and the borrower in connection with or as an incident of a loan, whether designated as interest or as a financial charge or otherwise, except that the term does not include the following charges when made pursuant to law: late or delinquency charges; attorneys' and collection fees; insurance premiums, including premiums for credit life insurance; recording or filing fees, and all other charges which may lawfully be made on loans in addition to interest or finance charges.

[N.J.S.A. 17:13A-2(g) (emphasis added).]

Other statutes distinguish late fees from interest by either authorizing or prohibiting certain lending institutions from making such charges. N.J.S.A. 17:13-104b specifically authorizes New Jersey credit unions to charge late fees to its members.

Notwithstanding the provisions of R.S. 31:1-1 to the contrary, a credit union may charge, contract for, and receive interest on loans at a rate or rates agreed to by the credit union and the member. A credit union may charge late fees and lawful fees paid to any public officer for filing, recording, or releasing a document, and may charge collection fees, not to exceed 20% of the principle balance and interest outstanding, which may be added to the principal balance of any loan placed for collection after default thereon.

[N.J.S.A. 17:13-104b (emphasis added).]

N.J.S.A. 17:9A governs a banking institution's authority to make check loans and other loans, N.J.S.A. 17:9A-59.1 to -59.17, small business loans, N.J.S.A. 17:9A-59.25 to -59.39 and loans secured by a deposit, N.J.S.A. 17:9A-59.40-63. In defining the amount of interest permitted on each class of loans, the respective statutes specifically include only percentage rate interest, not other financial charges. Other charges are provided for in separate sections. For example, N.J.S.A. 17:9A-59.6, sets the rate of interest for advance loans. Later provisions provide for additional fees on advance loans, such as late charges, N.J.S.A. 17:9A-59.7, and service charges, N.J.S.A. 17:9A-59.8.

On the other hand, New Jersey's RISA prohibits lenders from charging late fees and other financial charges in addition to interest. The statute provides:

No retail seller, sales finance company, or holder shall charge, . . . directly or indirectly, any further or other amount for costs, charges, insurance premiums, examination, appraisal service, brokerage, commission, expense, interest, discount, fees, fines, penalties or other things of value in connection with . . . retail charge accounts other than the charges permitted by this act. . . .

[N.J.S.A. 17:16C-50.]

At the time this case was before the Court, the statute expressly authorized delinquency or late-payment charges on only retail installment contracts. N.J.S.A. 17:16C-42(a). On March 7, 1995, however, the statute was amended by L. 1995, c. 43, § 1, which specifically allows for late-payment charges on retail charge accounts. It provides in pertinent part that:

The holder of any retail charge account may collect a delinquency or collection charge in an amount not to exceed $10 if provided for in the retail charge account agreement, on any minimum payment which has not been paid in full for a period of 10 days after its due date, as originally scheduled.

[ L. 1995, c. 43, § 1.]

The effective date of the amendment was May 29, 1995, 90 days following its enactment. L. 1995, c. 43, § 2. Thus, for purposes of this appeal, defendant's late-fee charges were still illegal under RISA. This amendment to the statute indicates, however, that the legislature did not intend to include late-fee charges within its definition of interest; rather, it expressly specified when and under what conditions other non-percentage rate charges could be procured by lenders in addition to annual interest rate charges.

Moreover, the regulations governing banking specifically provide for the maximum rate of interest to be charged on the issuance of different types of loans. N.J.A.C. 3:1-1.1; N.J.A.C. 3:1-1.2. These regulations governing interest say nothing about other financial charges, such as late fees. Thus, the manner in which both the Legislature and the Department of Banking have chosen to regulate lender-authorized charges clearly supports the conclusion that late fees are distinct from interest and thus not contained within the accepted definition of interest. The dissent incorporates late fees, and presumably other similar charges, into the notion of traditional interest by homogenizing what the Legislature has meticulously separated. It does so only by obscuring the clear language and structure of the legislative treatment of interest and late fees. See Post at 87-90, 668 A.2d at 1062-1063.

The State Bank Parity Act, N.J.S.A. 17:13B-1 to -2, authorizes New Jersey banks to charge the same "rate of interest" charged by credit unions. N.J.S.A. 17:13B-2 provides:

Notwithstanding any provisions of R.S. 31:1-1 or any other statute to the contrary, any bank, savings bank, savings and loan association or credit union may charge a rate of interest on any class or type of loan at the rate of interest permitted to any other lender by the laws of this State on that class or type of loan.

[N.J.S.A. 17:13B-2 (emphasis added).]

The Assembly Banking and Insurance Committee Statement that accompanied this legislation indicates that the act was intended as a state-bank companion to section 85 of the NBA.

This legislation would give state chartered banks, savings banks, savings and loan associations, and credit unions the same "most-favored-lender" authority that national banks presently enjoy . . . In practice, a national bank may charge interest on any type of loan at the highest rate allowed to any lender in the state making any similar type of loan. Thus, in certain cases, national banks may now use the rate permitted to be charged by secondary mortgage loan licensees, small loan companies (this rate will now apply to bank credit cards because of legislation passed last year), or home repair contractors. This legislation, therefore, provides parity to state-chartered institutions.

[Assembly Banking Insurance Committee, Statement to Assembly Bill No. 1986 (1981).]

Thus, while the Act provides for parity between the rates of interest charged by both banks and credit unions, the act does not explicitly authorize banks to charge other types of fees. Furthermore, there is no indication that the Legislature implicitly intended these other fees in the State Bank Parity Act. Indeed, the fact that the Legislature has passed separate statutes that expressly authorize the imposition of discrete fees and charges, (see discussion, supra, at 59-62, 668 A.2d at 1047-1049), in contrast to interest, underscores the understanding that those types of charges are not contemplated by the State Bank Parity Act. The clearest indication of the Legislature's intent to distinguish between interest rates and late fees is in the language of its recent amendment to RISA, in which it expressly authorizes holders of retail charge accounts, as well as retail installment contracts, to charge late fees. The Legislature obviously enacted this law because it wanted to enable banks and other retail charge-account holders to charge late fees that credit unions were permitted to charge under N.J.S.A. 17:13-104b. Had the State Bank Parity Act provided parity between lenders as to specific non-interest rate charges, there would have been no need for the amendment because holders of retail charge accounts would have been entitled, pursuant to the parity act, to charge the late fees that credit unions were authorized to charge. Courts should avoid a construction that would render legislative enactments meaningless. State v. Reynolds, 124 N.J. 559 , 592 A.2d 194 (1991). Thus, by excluding discrete charges from the parity act, the Legislature retained flexibility with respect to the non-percentage rate fees different lenders were permitted to charge their customers. For example, retail charge account holders are limited to a $10 late-fee per default period, while credit unions have no such limitation.

The language of RISA itself indicates the legislative intent to leave room for subsequent legislative initiatives to allow different lenders to make discrete non-percentage rate charges; it states that a retail seller, sales finance company or holder cannot charge additional fees or charges "other than the charges permitted by this act." Thus, the Legislature, in reserving within the statute the ability to authorize certain charges, has correctly recognized that there may be specific reasons for treating different lenders differently. For example, there may be specific reasons for allowing a credit union, rather than a bank, to charge late fees. Credit unions are small, individualized lenders which do not cater to a large market. Furthermore, credit unions have a genuine social welfare purpose. In assisting their members they cannot spread costs like banks. Thus, they must be permitted to take actions, such as charging late fees, to help insure their solvency.

The dissent points to a letter from the Department of Banking to support its theory that the State Bank Parity Act includes late fees in its definition of interest. Post, at 89-90, 668 A.2d at 1063 (citing Letter from Francis P. Carr, Assistant Commissioner, Department of Banking (Oct. 14, 1994)). Relying on an informal and isolated expression of agency interpretation has limited authoritative weight and does little to buttress its argument. Here, we are not presented with duly promulgated regulations that express legislative intent. Metromedia, Inc. v. Director, Div. of Taxation, 97 N.J. 313 , 331, 478 A.2d 742 (1984) (emphasizing that procedural requirements for passage of rules, involving notice and public participation, are given authoritative weight). Nor are we confronted with even a course of regulatory conduct that reflects a clear and consistent administrative understanding as evidence of an underlying legislative intent. Body-Rite Repair Co., Inc. v. Director, Div. of Taxation, 89 N.J. 540 , 545-46, 446 A.2d 515 (1982) (holding that practical administrative construction of statute over period of years without interference by Legislature is evidence of conformity with legislative intent and should be given great weight by court). Clearly, a single letter from the Department of Banking does not constitute a settled or widespread course of administrative conduct that can be equated with the interpretive authority of a duly promulgated rule. Moreover, it cannot provide a meaning that is neither expressed in the statute, nor in the legislative scheme governing banking. Our deference does not go so far as to permit an administrative agency under the guise of an administrative interpretation to give a statute any greater effect than is permitted by statutory language. In re Adoption of N.J.A.C. 7:26B, 128 N.J. 442 , 450, 608 A.2d 288 (1992) (citation omitted).

This Court has found no legislative authority to support the contention that interest in the context of either the State Bank Parity Act or the NBA encompasses a variety of lender-imposed fees and financial requirements that are independent of a numerical percentage rate. Thus, we can conclude only that neither Congress, in passing the NBA, nor the New Jersey Legislature, through its own parity act, intended to include late fees in its definition of interest for the purpose of preventing discrimination against out-of-state lenders.

V

Defendant argues that although the new RISA amendment is inapplicable to the charges assessed in this case, the fact that New Jersey credit unions were permitted to charge late fees at the time defendant procured those fees, pursuant to the most-favored-lender doctrine, entitled out-of-state national banks, like defendant, to charge late fees. We disagree.

Although a national bank may "borrow" the interest rate from any lending institution in its home state, without regard to whether that institution is actually "competitive" with a national bank, a national bank is not authorized to charge late fees simply because a state credit union is so authorized in a state other than its home state. Inter-state parity, as established in Marquette, is commonly identified as the notion that a national bank is entitled to export the interest authorized by its home state to borrowers located in other states that authorize a lower interest rates. Marquette, supra, 439 U.S. at 313-14, 99 S.Ct. at 548, 58 L.Ed.2d at 545 . The defendant seeks to extend this inter-state parity notion by arguing that a foreign national bank lending to customers in New Jersey is entitled to charge the interest authorized by the state in which the bank is located or the interest authorized in New Jersey, whichever is higher, and that for purposes of determining what interest can be exported, all of the extra charges authorized by the borrower's state can be included as well. Thus, it argues a foreign national bank can charge late fees because New Jersey credit unions are permitted to charge them and, under the most-favored-lender doctrine, national banks can charge the same interest — in its most expansive form — as any state lender. The argument, we find, overreaches the federal statutory scheme.

Section 85 of the NBA provides in pertinent part:

Any [national bank] association may take, receive, reserve, and charge on any loan or discount made, or upon any notes, bills of exchange, or other evidence of debt, interest at a rate allowed by the laws of the State, Territory, or District where the bank is located, or at a rate of 1 per centum in excess of the discount rate on ninety-day commercial paper in effect at the Federal reserve bank in the Federal reserve district where the bank is located, whichever may be the greater, and no more, except where by the laws of any State a different rate is limited for banks organized under state laws, the rate so limited shall be allowed for associations organized or existing in any such state under this chapter.

[ 12 U.S.C.A. § 85 (emphasis added).]

Section 86 reads in pertinent part:

The taking, receiving, reserving or charging a rate of interest greater than is allowed by section 85 of this title, when knowingly done, shall be deemed a forfeiture of the entire interest . . . In case the greater rate of interest has been paid, the person by whom it has been paid, . . . may recover back, . . . twice the amount of the interest thus paid. . . .

[ 12 U.S.C.A. § 86.]

For purposes of section 85, a national bank is located either in the place designated in its organizational certificate or in the places in which it has established authorized branches. Marquette, supra, 439 U.S. at 309 n. 21, 99 S.Ct. at 546 n. 21, 58 L.Ed.2d at 542-43 n. 21. A plain reading of the statute and most cases interpreting it indicate that a national bank is permitted to charge the interest rate of the state in which it is located, not the interest rate of the state in which the out-of-state customer is located. Id. at 301, 99 S.Ct. at 542, 58 L.Ed.2d at 537-38 (ruling that section 85 authorizes a national bank based in one state to charge its out-of-state credit card customers an interest rate on unpaid balances allowed by its home state, when that rate is greater than that permitted by the state of the bank's nonresident customers); Cades v. H R Block, Inc., 43 F.3d 869, 874 (4th Cir. 1994) (determining that Delaware law applied to fix the interest rate when the bank located in Delaware, even though the loan occurred in South Carolina; "section 85, which looks to the interest rates allowed by the state where the bank is located — not where the borrower is located or where the loan transaction may be said to have occurred").

Moreover, there is some indication that it is illegal for a national bank to charge interest in excess of that amount permitted in its home state. In Panos v. Smith, supra, 116 F.2d at 446, the court read sections 85 and 86 together to find that the NBA forbids a national bank to collect a higher rate of interest than is permitted by the law of the state in which it is located. Although none of these cases specifically dealt with a situation where the interest in the state of the customer was higher or more permissive than the national bank's home state, the basic understanding that resort to the higher level of interest would not be allowed is readily inferable from their treatment of the subject.

The theory of the NBA, as applied by federal and state courts, is that the borrower's state usury laws can be discarded because the customer either taking out a loan or using her "lender credit card" partakes in a transaction in the national lender's home state. See Marquette, supra, 439 U.S. at 318-19, 99 S.Ct. at 550, 58 L.Ed.2d at 548 (recognizing that impairment of state usury laws "has always been implicit in the structure of the National Bank Act, since citizens of one state were free to visit a neighboring state to receive credit at foreign interest rates"); Schumacher v. Lawrence, 108 F.2d 576, 577 (6th Cir. 1940) (stating that the question whether the rate of interest charged by a national bank is usurious is decided according to the law of the state in which the transaction occurs); Haas v. Pittsburgh Nat'l Bank, 60 F.R.D. 604 , 608 n. 3 (W.D.Pa. 1973) (same); Fisher v. First Nat'l Bank, supra, 548 F.2d at 257 ("A[n] [Iowa] customer using this "lender credit card" . . . communicates or indicates his intention to establish the credit card arrangement with BankAmericard when the lender, through banking channels, receives in the State of Nebraska the draft of the customer."). It is clear that Congress intended that the NBA and DIDA immunize national banks and out-of-state federally insured banks that lend money beyond their home-state's borders from local usury laws that might give local banks a competitive advantage. E.g., Tiffany, supra, 85 U.S. at 412-13, 21 L.Ed. at 863-64 (holding that Congress, by enacting NBA, intended to protect national banks from hostile state usury laws); Sherman v. Citibank (South Dakota), N.A., 272 N.J. Super. at 440, 640 A.2d 325 (same); Hunter v. Greenwood Trust Company, 272 N.J. Super. at 530, 640 A.2d 855 (same); 12 U.S.C.A. 1831d(a) (permitting State-chartered insured depository institutions to charge interest rates permitted in their home state "[i]n order to prevent discrimination against State-chartered insured depository institutions"). Thus, the statutes were intended to prohibit states from forcing national banks to charge a lower rate of interest to customers located outside of the national bank's home state than they would be permitted to charge their customers located in the home state.

We do not believe prohibiting national lenders from charging the rate of interest permitted by the laws of a foreign state would be considered discrimination when the national bank was not organized in that state and would not be able to charge higher interest rates except by taking advantage of the laws of the foreign state. New Jersey's RISA does not conflict with the most-favored-lender doctrine in this case, and thus New Jersey should be permitted to prohibit out-of-state lenders from charging late-fees to New Jersey residents, because, at the outset of this case, New Jersey banks were also prohibited from charging those fees. This finding would enable state usury laws to remain vital and controlling over non-interest rate credit terms. Consumer credit protection is a fundamental local interest, long recognized by Congress, and it thus should not be displaced by the sweeping preemption urged by defendant.

Because at the time of this appeal, RISA prohibited both New Jersey and national retail charge account holders from charging late fees, we hold that defendant's late-fee charges violated this state's usury laws and are thus impermissible.

VI

Although the late-fee charges at issue in this case are impermissible under the RISA statute as it existed when those fees were assessed, we acknowledge, as suggested by the parties, that such charges assessed after May 29, 1995 do not appear to be illegal under that statute. As earlier discussed, supra at 61-62, 668 A.2d at 1048-1049, the Legislature amended the statute to permit "the holder of any retail charge account [to] collect a delinquency or collection charge" of no more than $10. L. 1995, c. 43, § 1. Pursuant to the statute, a "holder" is "any person, including a retail seller, who is entitled to the rights of a seller under a retail installment contract or retail charge account." N.J.S.A. 17:16C-1(m). A "retail charge account" is

any account . . . established by agreement which prescribes the terms under which a retail buyer may from time to time purchase or lease goods or services which are primarily for personal, family or household purposes, and under which the unpaid balance thereunder, whenever incurred is payable in one or more installments and under which a time price differential may be added in each billing period as provided herein. Retail charge account also includes all accounts arising out of the utilization by the holder of a credit card . . . issued by a sales finance company, giving the holder the privilege of using the credit card . . . to become a retail buyer in transactions out of which debt arises.

[N.J.S.A. 17:16C-1(r).]

Although the statute does not expressly include banks within these definitions, clearly banks have for years been performing the functions attributable to holders of retail charge accounts. See N.J.S.A. 17:3B-4 to -28 (Market Rate Consumer Loan Act) (authorizing New Jersey banks to offer revolving credit plans at an interest rate agreed to by lender and borrower); N.J.S.A. 17:9A-59.1 (permitting advance loans by banks). In fact, the statute expressly provides that "any banking institutions authorized to do business in this State, shall be authorized to transact business as a sales finance company." N.J.S.A. 17:16C-2. Thus, it appears that the Legislature intended to include banks that issue credit cards within those institutions authorized to assess late charges on overdue charge accounts. Therefore, a bank may contract to charge the delinquency fee on the same basis as any other "holder of any retail charge account" in New Jersey.

Nothing in the statute indicates a legislative intention to allow state banks to charge delinquency fees while prohibiting national banks and federally-insured state banks from assessing those fees. In fact, the statute defines banking institutions generally as "any bank, national banking association, savings bank or federally chartered savings bank authorized to do business in this State". N.J.S.A. 17:16C-1(n). There is no distinction between a national banking association and an association under state laws except where the distinction is specifically made by Congress. Anderson v. First Security Bank, 54 F. Supp. 937 (D. Idaho 1944). States may not discriminate against national banks with respect to general contract terms or charges. See Anderson Nat'l Bank v. Luckett, 321 U.S. 233, 64 S.Ct. 599, 88 L.Ed. 692 (1944) (national banks are subject to state laws unless those laws infringe upon national banking laws or impose undue burden on performance of bank's functions); National State Bank v. Long, 630 F.2d 981, 985 (3d Cir. 1980). Thus, national banks, as well as federally-insured state banks, are permitted to charge the late fees authorized by statute to the same extent as state banks.

However, New Jersey retains the authority to regulate on a non-discriminatory basis all non-interest rate contractual terms and conditions of a bank as a holder of a retail charge account. The Supreme Court has held that state law controls a bank's right to collect its debts.

[National banks] are governed in their daily course of business far more by the laws of the State than of a nation. All their contracts are governed and construed by State laws. Their acquisition and transfer of property, their right to collect their debts, and their liability to be sued for debts, are all based on State law. It is only when the State law incapacitates the banks from discharging their duties to the government that it becomes unconstitutional.

[ National Bank v. Commonwealth, 76 U.S. (9 Wall) 353, 362, 19 L.Ed. 701 (1870).]

Thus, it would appear that a national bank and a federally-insured state bank may, as of May 29, 1995, charge a delinquency fee in accordance with the authorization now given by the statute. See L. 1995, c. 43.
