MEMORANDUM OPINION AND ORDER
Plaintiff Laura Swanson filed a Second Amended Complaint, on behalf of herself and all other similarly situated residents of the State of Illinois, alleging that Defendants Bank of America, N.A.’s (“the Bank”) and FIA Card Services, N.A.’s (“FIA”) retroactive application of interest rate increases violated the Truth in Lending Act (“TILA”), the Illinois Consumer Fraud & Deceptive Business Practices Act (“ICFA”), and unjustly enriched Defendants. Before the Court is Defendants’ motion to dismiss Plaintiff Swanson’s claims pursuant to Federal Rule of Civil Procedure 12(b)(6). For the following reasons, the Court grants Defendants’ motion.
BACKGROUND
I. Relevant Facts
Plaintiff opened a credit card account with the Bank. 1 In connection with this account, Plaintiff received term agreements which indicated that Plaintiff had a $5,000 credit limit available on the account. (R. 41-6, at p. 2.) The agreements also noted that if Plaintiff twice exceeded the credit limit during a 12-month billing cycle, the Bank could increase the interest rate on the account. Id. Defendants’ revised credit card term agreements state that each interest rate increase “will be effective as of the first date of the billing cycle in which the Default Rate is applied.” (R. 41-6, at p. 2.) Plaintiff exceeded the credit limit in August 2007 and again in November 2007. (R. 41-7, at p. 2, 9.) As a result, Defendants increased the interest rate- of Plaintiffs account from 18.24 percent to 32.24 percent, and applied the higher rate to the beginning of the November billing cycle that had just ended. (R. 34-1, at ¶¶ 12-13.) Due to the increase, Defendants added approximately sixty dollars in interest charges to Plaintiffs November bill. (Id. at ¶ 15.)
*823 In her SAC, Plaintiff Swanson makes three claims against Defendants. She first alleges that Defendants violated TILA, specifically 15 U.S.C. § 1601(a), by failing to provide her with written notice of the specific rate increase before the increase became effective. (R. 34-1, at ¶ 25.) Second, Swanson alleges that Defendants were unjustly enriched by the retroactive rate increase, which Plaintiff Swanson argues was an illegal penalty. (Id. at ¶ 29.) Third, she alleges that Defendants violated the ICFA, specifically 815 ILCS 505/1, et seq., by engaging in unfair and deceptive practices. (Id. at ¶ 35.) Defendants have moved to dismiss the SAC, arguing that Plaintiff has failed to state a claim upon which relief may be granted, and that the state law claims are preempted by federal law.
ANALYSIS
I. Legal Standard on a Rule 12(b)(6) Motion
“A motion under Rule 12(b)(6) challenges the sufficiency of the complaint.”
Christensen v. County of Boone, Ill.,
II. Exhibits
Defendants have asked the Court to consider various exhibits in connection with their motion. In a typical 12(b)(6) motion, the Court does not consider documents extrinsic to the complaint.
See
Fed. R.Civ.P. 12(d);
ABN AMRO, Inc. v. Capital Int’l Ltd.,
No. 04 C 3123,
First, Defendants have asked the Court to consider statements reflecting Plaintiffs account balances. (R. 41-4; R. 41-7.) These statements are referenced in the SAC, and the facts contained within these statements, particularly the change in interest rates and the number of defaults, are important to Plaintiffs claims. (R. 34-1, at ¶ 11.) Moreover, the authenticity of *824 these documents is not questioned. (R. 34-1, at ¶ 11.) As such, the Court will consider the account statements.
Defendants next ask the Court to consider a credit card term agreement entered into by Plaintiff and the Bank. (R. 41-2; R. 41-3.) Although the SAC is silent as to Swanson’s receipt of the agreement, the Court may consider extrinsic documents in a 12(b)(6) motion where the documents are implicitly referenced within the complaint.
Tierney,
Defendants have also asked the Court to consider a supplemental agreement reiterating many of the same terms as the initial agreement. (R. 41-5; R. 41-6.) Although the supplemental agreement is not explicitly referenced in the SAC, receipt of the documents is implicitly acknowledged. (R. 45-1; PL’s Resp. to Def.’s Mot. for Dismissal 4-5.) These documents too are central to Plaintiffs claims regarding notice of the interest rate increase, and Plaintiff does not question the authenticity of the revised agreement. The Court will consider the supplemental credit card term agreement.
III. Plaintiffs Truth In Lending Act (“TILA”) Claim
A. Subject Matter Jurisdiction
Although Plaintiffs SAC seeks to invoke only the Court’s diversity jurisdiction pursuant to 28 U.S.C. § 1332(d), the Court has federal question jurisdiction over Plaintiffs federal TILA claim. 28 U.S.C. § 1331 (“The district courts shall have original jurisdiction of all civil actions arising under the Constitution, laws, or treaties of the United States.”);
see, e.g., Cunningham v. Nationscredit Fin. Servs. Corp.,
B. TILA Requirements
TILA was designed to, among other things, protect consumers in credit transactions by requiring strict disclosures from lenders. 15 U.S.C. § 1601(a),
et seq; Household Credit Servs. v. Pfennig,
TILA and Regulation Z govern open-end credit plans, like Plaintiff Swanson’s credit card account.
See Pfennig,
In addition to initial disclosure requirements, TILA also requires creditors to notify consumers of subsequent changes to the initially disclosed terms. See 12 C.F.R. § 226.9(c)(1) (“Whenever any term required to be disclosed under § 226.6 is changed or the required minimum periodic payment is increased, the creditor shall mail or deliver written notice of the change to each consumer who may be affected.”). The Official Commentary, however, explains that a creditor is not required to make a subsequent disclosure if the “specific change” is set forth in the initial disclosure. 12 C.F.R pt. 226, Supp. 1, § 226.9(c), cmt. 1. Specifically, Comment 1 states that:
No notice of a change in terms need be given if the specific change is set forth initially, such as Rate increases under a properly disclosed variable-rate plan, a rate increase that occurs when an employee has been under a preferential rate agreement and terminates employment, or an increase that occurs when the consumer has been under an agreement to maintain a certain balance in a savings account in order to keep a particular rate and the account balance falls below the specified minimum. In contrast, notice must be given if the contract allows the creditor to increase the rate at its discretion but does not include specific terms for an increase (for example, when an increase may occur under the creditor’s contract reservation right to increase the periodic rate) ...
Id.
The resolution of Plaintiffs TILA claim hinges on whether the first or second sentence of Comment 1 applies to Defendants’ actions. Defendants argue that their initial disclosures (in the credit card agreements) set forth the “specific change” of which Plaintiff complains, and therefore they did not need to provide subsequent notice pursuant to the first sentence of Comment 1. Plaintiff, on the other hand, argues that Defendants’ practice of increasing interest rates upon a consumer’s delinquency falls under the second sentence of Comment 1 both because it fails to satisfy the “specific change” requirement and because Defendants maintained discretion to increase the rate.
C. Specific Change
To determine whether Defendants’ initial disclosures set forth a “specific change” in terms, the Court first looks to the agreements themselves. In addition to listing the specific act which triggers the interest rate increase, namely twice exceeding the credit limit, the agreements set forth the method Defendants used to calculate the default interest rate, as well as maximum default interest rate. (R. 41-3.) Moreover, the term agreements specify the time at which the interest rate change will become effective upon default — the first day of the billing cycle. (R. 41-6.) Together, these terms disclose a “specific change” under the first sentence of 12 C.F.R. pt. 226, Supp. I, § 226.9(c), cmt. 1. Given the specificity of the terms of the rate increase in the agree
*826
ments, Defendants’ practice does not constitute a “change of terms” under 12 C.F.R. 226.9(c)(1).
See Williams v. Washington Mutual Bank,
The Board’s comments support that a rate increase such as the one at issue here could constitute a “specific change.” In proposing language to amend the current law in June 2007, the Board explained the current state of the law:
Advance notice is not required in all cases. For example, if an interest rate or other finance charge increases due to a consumer’s default or delinquency, notice is required, but need not be given in advance. See current § 226.9(c)(1); comment 9(c)(l)-3. Furthermore, no change-in-terms notice is required if the specific change is set forth initial-Ig bg the creditor in the account-opening disclosures. See current comment 9(c)-l. For example, some account agreements permit the card issuer to increase the periodic rate if the consumer makes a late payment. Because the circumstances of the increase are specified in advance in the account agreement, the creditor currently need not provide a change-in-terms notice; under current § 226.7(d) the new rate will appear on the periodic statement for the cycle in which the increase occurs.
72 Fed.Reg. 33009 (June 14, 2007) (emphasis added). The Board’s late payment example is directly analogous to the Plaintiffs default. As a Board staff opinion of TILA, this interpretation is dispositive unless “demonstrably irrational.”
Milhollin,
D. Defendants’ Discretion
In the face of this authority, Plaintiff argues that the notice given by Defendants does not satisfy TILA requirements because Defendants retained discretion to decide whether to increase the interest rate in the event Plaintiff defaulted. (R. 45-1; Pl.’s Resp. to Def.’s Mot. for Dismissal 4.) This argument fails. Relying on language in the credit card agreement stating that Defendants “may increase” Plaintiffs rate in the event Plaintiff fails to follow the terms of the agreement, Plaintiff argues that Defendants’ conduct is of the discretionary type governed by the second sentence of Comment 1. The Official Commentary, however, explains that subsequent notice is required only where a creditor has discretion to
increase
a consumer’s interest rate. 12 C.F.R pt. 226, Supp. 1, § 226.9(c), cmt. 1. (“notice must be given if the contract allows the creditor to increase the rate at its discretion”). Thus, while it is true that Defendants maintain discretion to
not increase
a consumer’s ■ interest rate once the specific change occurs, Defendants’ ability to increase the rate is tied to triggering events solely within the consumer’s control.
See, e.g., Williams,
E. Comment 3
Plaintiff also argues that Comment 3 to Section 226.9(c)(1) supports her position that Defendants’ practice violates TILA’s disclosure requirements. Comment 3 dispenses with a creditor’s general obligation to provide fifteen days advance notice of a change in terms in the event that “there is an increased periodic rate or any other *827 finance charge attributable to the consumer’s delinquency or default.” See 12 C.F.R pt. 226, Supp. 1, § 226.9(c)(1), cmt. 3. In place of the fifteen day advance notice requirement, Comment 3 clarifies that a creditor may deliver notice “as late as the effective date of the change.” Id. Plaintiff argues that Comment 3 requires a consumer to provide notice of all interest rate increases attributable to a consumer’s delinquency of default, prior to the effective date of this change. The Comment, however, does not go so far. Comment 3 applies only to the timing of a notice of “change of terms.” As discussed above, Defendants’ practice at issue here does not involve a “change of terms” as contemplated by Section 226.9(c)(1).
Based on the language of the regulations, the Official Commentary, and the Federal Reserve Board’s comments about the current state of the law, as well as the reasoning of the other district court cases deciding this exact issue, Defendants did not violate TILA by notifying Plaintiff of default rate increases only in their initial disclosures.
See Williams,
III. State Law Claims
In Counts II and III of the SAC, Plaintiff alleges that Defendants’ practice of retroactively increasing the interest rates violates state law.
A. Subject Matter Jurisdiction
Before turning to the substance of Defendants’ motion, the Court must first determine whether it has subject matter jurisdiction over Plaintiffs remaining state law claims. While Plaintiff and Defendants (in their removal papers) have asserted diversity jurisdiction under 28 U.S.C. § 1332(d), they have not properly alleged facts to support diversity jurisdiction. “It is axiomatic that a federal court must assure itself that it possesses jurisdiction over the subject matter of an action before it can proceed to take any action respecting the merits of the action.”
Cook v. Winfrey,
As an additional ground for jurisdiction, Defendants have raised in the removal papers — but not adequately briefed — the argument that federal question jurisdiction exists because Defendants contend that the state law claims are preempted by federal law. (R. 1-1, at ¶¶ 32-34.) Without a more developed argument, the Court cannot rely on this purported basis for jurisdiction. Nonetheless, the Court has discretion to retain jurisdiction over the supplemental state law claims because they are closely related to Plaintiffs TILA claim, over which the Court has original jurisdiction under 28 U.S.C. § 1331.
See
28 U.S.C. 1367(a). This is true even
*828
though the Court dismissed the TILA claim.
See
28 U.S.C. § 1367(c)(3);
Dargis v. Sheahan,
B. Count III — The Illinois Consumer Fraud Act
Plaintiff argues in Count III of the SAC that Defendants violated the ICFA by imposing retroactive rate increases without advance notice. (R. 34-1, at ¶¶ 33-38.) For the first time in their Reply Brief, Defendants squarely argue that compliance with TILA establishes compliance with the ICFA. (R. 46-1, at p. 12-13.) Although arguments raised for the first time in a reply brief generally are waived,
Nelson v. La Crosse County Dist. Atty.,
The ICFA does not apply “to Actions or transactions specifically authorized by laws administered by any regulatory body or officer acting under statutory authority of this State or the United States,” or to “conduct in compliance with the orders or rules of or a statute administered by a Federal, state or local governmental agency.” 815 ILCS 510/4(1); 815 ILCS 505/10b(1); see
Allen v. Aronson Furniture Co.,
C. Illegal Penalties and Unjust Enrichment Claim(s)
In Count II, Plaintiff purports to bring a cause of action for “collection of illegal penalties” and for “unjust enrichment.” (R. 34-1, at ¶¶ 27-32.) Despite the heading “unjust enrichment” (R. 34-1, at ¶ 26), Count II of the SAC appears to allege that Defendants’ practice of retroactively increasing rates violates a Delaware banking law requirement that interest rates on credit cards must be changed “in accordance with a schedule or formula.” 5 Del.Code § 944. It is unclear from the *829 SAC whether Plaintiff attempts to bring a claim for unjust enrichment under Illinois (or perhaps Delaware) law, 2 an illegal penalties claim under 5 DeLCode § 944, or perhaps some combination of the three.
To the extent Plaintiff seeks to bring an “illegal penalties” claim under Delaware law, that claim fails. As a starting point, the supplemental credit card agreement contains a choice of law provision maintaining that it “is governed by the laws of the State of Delaware.” (R. 41-5.) Plaintiff alleges that Defendants’ “retroactive rate increase violates Delaware banking law, 5 DehCode § 944, because it is not made pursuant to a schedule or formula stated in the credit card agreement.” Defendants point out, however, that Section 944 of the Delaware code specifically authorizes Defendants’ conduct, and thus forecloses this avenue to Plaintiff. (R. 40-1, at p. 16 n. 7.) Section 944 states:
If the agreement governing the revolving credit plan so provides, the periodic percentage rate or rates of interest under such plan may vary in accordance with a schedule or formula ... Without limitation, a permissible schedule or formula hereunder may include provision in the agreement governing the plan for a change in the periodic percentage rate ... contingent upon the happening of any event or circumstances specified in the plan, which event or circumstance may include the failure of the borrower to perform in accordance with the terms of the plan.
Del.Code § 944 (emphasis added). Here, Defendants applied the interest rate increase in accordance with the agreements, which permitted an interest rate increase in the event Plaintiff failed to comply with the terms of the plan (by twice exceeding her credit limit). By describing the events which cause the rate increase to occur, Defendant has complied with Section 944.
See, e.g., Evans,
A state law claim for unjust enrichment also fails.
See Dawson,
V. Preemption
Because Plaintiffs state law claims fail to state a cause of action, the Court does not reach the issue of whether those claims are preempted by federal law.
CONCLUSION
For the foregoing reasons, the Court dismisses Counts I with prejudice and dismisses Counts II and III without prejudice.
Notes
. The Bank and FIA are corporate affiliates. (R. 34-1, at ¶ 4.)
. Plaintiff failed to address the choice of law issue with regard to the unjust enrichment claim. Defendants, for their part, have asserted that Plaintiff brought an unjust enrichment claim under Illinois common law. (R. 1-1, at ¶ 2; R. 40-1, at p. 9) Although the Court does not definitively resolve the issue, it is clear that in applying Illinois choice of law rules,
