FINDINGS OF FACT AND CONCLUSIONS OF LAW
MARGARET M. MORROW, District Judge.
On July 11, 2008, the Office of Thrift Supervision (“OTS”) closed IndyMac Bank, F.S.B. (“IndyMac”) and appointed the Federal Deposit Insurance Corporation (“FDIC”) as the bank’s receiver pursuant to 12 U.S.C. § 1821(c)(2)(A). That same day, the FDIC formed IndyMac Federal Bank, a newly chartered depository institution, and transferred IndyMac’s insured deposits to it. The FDIC made deposit insurance determinations for accounts held at IndyMac and notified depositors of the determinations via letter. Some depositors, including plaintiffs, later filed actions challenging the FDIC’s deposit insurance determinations and/or alleging wrongful acts by IndyMac or its former employees prior to commencement of the receivership.
The parties filed opening briefs on September 14, 2009;1 the FDIC filed a re[853]*853sponsive brief on September 28, 2009.2 On July 31, 2009, the court granted plaintiffs’ request for oral argument and set a hearing for October 19, 2009.
I. FINDINGS OF FACT
A. The Accounts
1. Plaintiffs Philemon Tam, Kathy T-M Tam, Titus Tambunan, Christine Tam, and Victor Tam opened nine accounts with IndyMac prior to July 11, 2008.3
2. Prior to July 11, 2008, account XXXXXX7443 had a balance of $8,243.43 and was held in the name of Kathy T-M Tam. Account XXXXXX1808 had a balance of $14,088.64 and was also held in the name of Kathy T-M Tam. Account XXXXXX7442 had a balance of $18,313.30 and in the name Philemon Tam. Account XXXXXX8867 had a balance of $4,039.54 and was held in the name of Victor C. Tam, while account XXXXXX7347 had a balance of $561,762.46 and was held by Kathy T-M Tam in trust for (“ITF”) Christine Tam, Philemon Tam, Victor Tam, and Daphne Malatesta. Account XXXXXX0218 had a balance of $742,638.17 and was held by Philemon Tam and Kathy T-M Tam ITF Christine Tam, Victor Tam, and Daphne Malatesta. Account XXXXXX1399 had a balance of $10,063.23 and was held by Titus Tambunan ITF Christine and Victor Tam. Account XXXXXX8317 had a balance of $202,468.12 and was held by Titus Tambunan ITF Christine and Victor Tam, while account XXXXXX2173 had a balance of $540,729.07 and was held by Titus Tambunan ITF Christine and Victor Tam.4 The funds deposited in the nine accounts belonging to plaintiffs totaled $2,102,345.96.5
3. Accounts XXXXXX7347, XXXXXX0218, XXXXXX1399, XXXXXX8317, and XXXXXX2173 were informal revocable trust accounts.6 Accounts XXXXXX7443, XXXXXX1808, XXXXXX7442, and XXXXXX7442 were single ownership accounts.7
4. Account XXXXXX7347 was held by Kathy T-M Tam. The beneficiaries for this account were Philemon Tam, her husband, Christine and Victor Tam, her children, and Daphne Malatesta, her granddaughter. Account XXXXXX0218 was held by Philemon Tam and Kathy T-M Tam. The beneficiaries for this account were Chris[854]*854tine and Victor Tam, the depositors’ children, and Daphne Malatesta, their granddaughter. Accounts XXXXXX1399, XXXXXX8317, and XXXXXX2173 were held by Titus Tambunan. The beneficiaries for these accounts were Christine and Victor Tam, his niece and nephew respectively.8
B. The FDIC’s Insurance Determination
5. The FDIC as receiver for IndyMac assigned Michael Norton to review deposit insurance coverage and claims arising out of IndyMac’s failure. Norton reviewed the nine accounts at issue in this case.9
6. On July 12, 2008, Norton interviewed Philemon Tam and explained his preliminary determination regarding the amount of insured and uninsured funds in the accounts. Tam indicated that he would fill out and fax to Norton “Declarations of Testamentary Deposit” for each informal trust account. Tam requested that Norton provide a preliminary determination of insurance coverage, and Norton informed him that approximately $1,250,000.00 of the funds appeared to be uninsured.10 The declarations that Tam subsequently provided listed owners and beneficiaries for each of the revocable trust accounts that were not reflected in IndyMac’s records at the time it closed on July 11, 2008.11 As a result, the FDIC relied on the bank’s records in making its deposit insurance determination.12
7. Norton concluded that accounts XXXXXX7443, XXXXXX1808, XXXXXX7442, and XXXXXX7442 were single ownership accounts. Single ownership accounts owned by Kathy T-M Tam (XXXXXX7443 and XXXXXX1808) had a balance of $22,332.07. The single ownership account owned by Philemon Tam (XXXXXX7442) had a balance of $18,313.30. The single ownership account owned by Victor Tam (XXXXXX8867) had a balance of $4,039.54. Each of these single ownership accounts was fully insured, as each had a balance less than $100,000.13
8. Norton concluded that account XXXXXX7347 was held by Kathy T-M Tam. Norton concluded that XXXXXX0218 was held by Philemon and Kathy T-M Tam. The beneficiaries for both accounts were Christine and Victor Tam, the depositors’ children, and Daphne Malatesta, their granddaughter. In addition, Philemon Tam was a beneficiary on account XXXXXX7347. Norton concluded that under the deposit insurance rules then in effect, the two accounts had seven “beneficial relationships,” defined as a relationship between one trustee and one beneficiary.14 He found that all seven beneficial relationships involved qualifying beneficiaries (spouse, children, and grandchild).15
9. Norton determined that because account XXXXXX7347 had four beneficial relationships, each beneficial relationship was entitled to a one-quarter share of $140,440.62.16 Because account XXXXXX0218 had six beneficial relation[855]*855ships, he found that each beneficial relationship was entitled to a one-sixth share equal to $123,773.03.17 Three beneficial relationships—Kathy T-M Tam ITF Christine Tam, Kathy T-M Tam ITF- Victor Tam, and Kathy T-M Tam ITF Daphne Malatesta—had an interest in both accounts; consequently, Norton aggregated the shares for a total of $264,213.64.18
10. Norton concluded that Philemon Tam ITF Christine Tam; Philemon Tam ITF Victor Tam; and Philemon Tam ITF Daphne Malatesta each held $123,773.03 in the two accounts. He concluded that Kathy T-M Tam ITF Christine Tam, Kathy T-M Tam ITF Victor Tam, and Kathy TM Tam ITF Daphne Malatesta each held $264,213.64 in the two accounts. Finally, he concluded that Kathy T-M Tam ITF Philemon Tam held a $140,440.62 interest in the accounts.19
11. Because each trust relationship was insured for $100,000, each of Philemon Tam ITF Christine Tam; Philemon Tam ITF Victor Tam; and Philemon Tam ITF Daphne Malatesta was $23,733.03 over the deposit insurance limit. Kathy T-M Tam ITF Christine Tam; Kathy T-M Tam ITF Victor Tam; and Kathy T-M Tam ITF Daphne Malatesta were each $164,213.64 over the deposit insurance limit, while Kathy T-M Tam ITF Philemon Tam was $40,440.62 over the deposit insurance limit.20
12. Norton concluded that the Titus Tambunan’s two accounts were held in trust for his niece and nephew. Because neither a niece nor a nephew is a qualifying beneficiary, Norton treated these funds as if they had reverted to the single ownership of Tambunan. As a single owner, Tambunan was insured for $100,000. Consequently, Tambunan’s accounts were $653,260.42 over the deposit insurance limit.21
13. Howard calculated the total combined account balance for the five revocable trust accounts as $2,057,661.05. As the accounts were insured only to $800,000, they were $1,257,661.05 over the deposit insurance limits.22
14. On August 5, 2009, the FDIC sent plaintiffs a Notice of Allowance of Claim (“Notice”) and a Receivership Certificate in the amount of $1,257,661.05.23
15. Based on the FDIC’s calculation that the ultimate resolution of IndyMac’s assets would result in a recovery of approximately 50% of the uninsured deposits of Indy-Mac, FDIC sent the Tams a 50% advance dividend in the amount of $628,830.53.24
16. On September 23, 2009, the FDIC notified the court that it had reviewed the accounts held by Tambunan and determined that Tambunan was entitled to an additional $100,000 in insurance, bringing the total insurance for all of plaintiffs’ accounts to $900,000. The supplemental briefing does not indicate the reasoning for this revision.25
[856]*856II. CONCLUSIONS OF LAW
A. Standard of Review
17. The FDIC’s determination of insurance coverage is governed by the Federal Deposit Insurance Act (“FDIA”), as amended, 12 U.S.C. §§ 1811 et seq. 18. The FDIC’s final determination “regarding any claim for insurance coverage [is] a final agency action renewable in accordance with” the Administrative Procedure Act (“APA”). 12 U.S.C. § 1821(f)(4). Under the APA, the court examines whether the FDIC’s decision was “arbitrary, capricious, an abuse of discretion or otherwise not in accordance with law.” 5 U.S.C. § 706(2)(A). Accordingly, the parties agree that the relevant question the court must answer is whether the FDIC’s action was arbitrary or capricious.26
19. Final agency decision is arbitrary and capricious if the agency ‘“has relied on factors which Congress has not intended it to consider, entirely failed to consider an important aspect of the problem, offered an explanation for its decision that runs counter to the evidence before the agency, or is so implausible that it could not be ascribed to a difference in view or the product of agency expertise.’ ” O’Keeffe’s Inc. v. U.S. Consumer Product Safety Commission, 92 F.3d 940, 942 (9th Cir. 1996) (quoting Motor Vehicle Manufacturers Association v. State Farm Mutual Automobile Insurance Co., 463 U.S. 29, 43, 103 S.Ct. 2856, 77 L.Ed.2d 443 (1983)).
20. A district court is limited to a review of the reasoning on which the agency relied in making its decision. Safe Air for Everyone v. U.S. E.P.A., 488 F.3d 1088, 1091 (9th Cir.2007) (citing SEC v. Chenery Corp., 318 U.S. 80, 87, 63 S.Ct. 454, 87 L.Ed. 626 (1943)). It can “uphold a decision of less than ideal clarity if the agency’s path may reasonably be discerned.” Motor Vehicle Manufacturers Association, 463 U.S. at 43, 103 S.Ct. 2856. Where an agency offers an “interpretation of its own regulation [that] reflects its considered views,” even if those views are developed in response to litigation and communicated in a legal brief, the court should accept the interpretation if convinced it is not “merely a post hoc rationalization.” Long Island Care at Home, Ltd. v. Coke, 551 U.S. 158, 171, 127 S.Ct. 2339, 168 L.Ed.2d 54 (2007). [857]*857See also Alaska v. Federal Subsistence Board, 544 F.3d 1089, 1094 (9th Cir.2008) (“While we may not fabricate a rational basis for an agency’s action, we will ‘uphold a decision of less than ideal clarity if the agency’s path may reasonably be discerned,’ ” quoting Motor Vehicle Manufacturers Association, 463 U.S. at 43, 103 S.Ct. 2856). “ ‘Nevertheless, the agency must examine the relevant data and articulate a satisfactory explanation for its action including a rational connection between the facts found and the choice made.’ ” Northwest Coalition for Alternatives to Pesticides (NCAP) v. United States Environmental Protection Agency, 544 F.3d 1043, 1048 (9th Cir.2008) (quoting Motor Vehicle Manufacturers Association, 463 U.S. at 43, 103 S.Ct. 2856).
21. “[A]n agency’s interpretation of its own regulations is ‘controlling’ unless ‘plainly erroneous’ or inconsistent with ‘the regulations being interpreted.’ ” Public Citizen v. Nuclear Regulatory Commission, 573 F.3d 916, 923 (9th Cir.2009) (quoting Long Island Care at Home, 551 U.S. at 171, 127 S.Ct. 2339). See also Long Island Care at Home, 551 U.S. at 170-71, 127 S.Ct. 2339 (“[A]s long as interpretive changes create no unfair surprise ... change in interpretation alone presents no separate ground for disregarding the Department’s present interpretation”); River Runners for Wilderness v. Martin, 574 F.3d 723, 736 (9th Cir.2009) (“[F]ederal agencies are entitled to some leeway when interpreting their own policies and regulations,” citing Stinson v. United States, 508 U.S. 36, 45, 113 S.Ct. 1913, 123 L.Ed.2d 598 (1993)). “In other words, we must defer to the [agency’s] interpretation unless an ‘alternative reading is compelled by the regulation’s plain language or by other indications of the [agency’s] intent at the time of the regulation’s promulgation.’ ” Thomas Jefferson University v. Shalala, 512 U.S. 504, 512, 114 S.Ct. 2381, 129 L.Ed.2d 405 (1994) (quoting Gardebring v. Jenkins, 485 U.S. 415, 430, 108 S.Ct. 1306, 99 L.Ed.2d 515 (1988)). See also Oregon Paralyzed Veterans of America v. Regal Cinemas, Inc., 339 F.3d 1126, 1131 (9th Cir.2003) (“When the meaning of regulatory language is ambiguous, the agency’s interpretation of the regulation controls ‘so long as it is ‘reasonable,’ that is, so long as the interpretation sensibly conforms to the purpose and wording of the regulations,’ ” quoting Martin v. Occupational Safety & Health Review Commission, 499 U.S. 144, 150-51, 111 S.Ct. 1171, 113 L.Ed.2d 117 (1991)); Wards Cove Packing Corp. v. National Marine Fisheries Service, 307 F.3d 1214, 1218 (9th Cir. 2002) (“An agency’s interpretation of regulations it is charged with administering is entitled to a high degree of deference and will be upheld as long as it is not plainly erroneous or inconsistent with the regulation”).
B. Whether the FDIC Properly Determined the Amount of Deposit Insurance to Which Plaintiffs Were Entitled under the Regulations Applicable on August 9, 2008
22. The FDIC’s deposit insurance determinations are governed the regulations set forth in 12 C.F.R. Part 330. Regulations governing recognition of deposit ownership and fiduciary relationships note that, except in circumstances not relevant here, when “determining the amount of insurance available to each depositor, the FDIC shall presume that deposited funds are actually owned in the manner indicated on the deposit account records of the insured depository institution.” 12 C.F.R. § 330.5(a)(1).27 See also Villafane-Neriz [858]*858v. F.D.I.C., 75 F.3d 727, 731 (1st Cir.1996) (holding that the FDIC “is entitled to rely exclusively on the account records of the failed institution,” and that “while ownership under state law is one prerequisite for insurance coverage, the deposit account records are controlling”). “Deposit account records” include “account ledgers, signature cards, certificates of deposit, passbooks, corporate resolutions authorizing accounts in the possession of the insured depository institution and other books and records of the insured depository institution, including records maintained by computer, which relate to the insured depository institution’s deposit taking function.” 12 C.F.R. § 330.1(e).28 As noted, plaintiffs did not seek leave to conduct further discovery, and do not object to the contents of the administrative record.
23. At the time IndyMac closed, revocable trust accounts were insured up to $100,000 per owner if certain conditions were met. First, the title of the account had to reflect that the funds were held pursuant to a formal revocable trust set up by an owner or grantor. The owner or grantor was required to retain ownership during his or her life. 12 C.F.R. § 330.10(f)(1), (4) (2008), 69 Fed.Reg. 2829-30 (Jan. 21, 2004) (stating that “revocable trust accounts held in connection with a formal revocable trust created by an owner/grantor and over which the owner/grantor retains ownership during his or her lifetime,” qualify for coverage if “the title of the account ... reflects] that the funds in the account are held pursuant to a formal revocable trust”). Second, while the beneficiaries need not be identified by name in the deposit account records, they must be “qualifying” beneficiaries. The “owner’s spouse, child/children, grandchild/grandchildren, pareni/parents, brother/brothers or sister/sisters” are “qualifying beneficiaries.” 12 C.F.R. § 330.10(a) (2008), 64 Fed.Reg. 15657 (Apr. 1, 1999).29
24. When a revocable trust account was established by more than one owner and held for the benefit of others, some or all of whom were qualifying beneficiaries, the regulation provided that the respective interests of each owner held for the benefit of each qualifying beneficiary would be separately insured up to $100,000. 12 C.F.R. § 330.10(d) (2008), 63 Fed.Reg. 25760-61 (May 11, 1998). The owners were presumed to have equal interests in the account unless otherwise stated in the deposit account records. Id.
25. While the trust owner was the insured party, insurance coverage was provided for the interest of each qualifying beneficiary up to $100,000. 12 C.F.R. [859]*859§ 330.10(a) (2008), 64 Fed.Reg. 15657 (Apr. 1, 1999); 12 C.F.R. § 330.10(f)(1) (2008), 69 Fed.Reg. 2829 (Jan. 21, 2004). If a named beneficiary of a revocable trust account was not a qualifying beneficiary, the funds held for the benefit of that beneficiary were treated as individually owned by the grantor. 12 C.F.R. § 330.10(c) (2008), 63 Fed.Reg. 25760 (May 11, 1998).
26. Stated differently, the FDIC insured each grantor up to $100,000 for the interest of each qualifying beneficiary. If each grantor held an amount for the benefit of the same qualifying beneficiary, those amounts were separately insured. 12 C.F.R. § 330.10(d) (2008), 63 Fed.Reg. 25760-61 (May 11, 1998); Advisory Opinion FDIC-05-05, Question Regarding Deposit Insurance for a “Spousal Revocable Living Trust,” 2005 WL 2979649, *1-2 (Sept. 12, 2005) (“Under this rule, the FDIC would assume ... that the two grantors ... have contributed equal amounts.... The amount contributed by each grantor for each ‘qualifying beneficiary’ would be insured separately”). In making its insurance determination, therefore, the FDIC assumes that, unless otherwise stated, each grantor has contributed 50% of the funds in the account. Advisory Opinion FDIC-05-05, 2005 WL 2979649 at *2 (“[Where B and C are two grantors], with an account balance of $550,000, the FDIC would assume that B has contributed $275,000 and that C has contributed $275,000. The funds contributed by B would be insured separately from the funds contributed by C”). It then analyzes insurance coverage as if the revocable trust account were two accounts, each holding 50% of the funds, and there were separate trustee-beneficiary relationships between each grantor and each beneficiary. Id. at *2-4. As a result, in a situation where there are two grantors and a single qualifying beneficiary, insurance coverage of $200,000 is available. Id. (describing a hypothetical in which a daughter is a qualifying beneficiary of both grantors, and each grantor is therefore insured to $100,000). Conversely, where a person is a qualifying beneficiary of one grantor, but a non-qualifying beneficiary of the second, only the qualifying relationship is insured.30
27. In this case, with respect to accounts XXXXXX7347 and XXXXXX0218, there are seven beneficial relationships. Of the seven beneficial relationships, all were qualifying relationships.31 There were no non-qualifying relationships. Consequently, each qualifying relationship was insured up to $100,000 for a total of $700,000.
28. The funds held by Tambunan for the benefit of non-qualifying beneficiaries were treated as owned by Tambunan. The FDIC thus determined that Tambunan was entitled to receive $100,000 in insurance coverage.
29. The FDIC’s final deposit determination regarding plaintiffs’ accounts was in accordance with the law and supported by the evidence upon which FDIC was required to rely. Although plaintiffs dispute whether the regulation in effect at the time the deposit insurance determination was made applies, and also contend that the regulation was too vague and complex to understand or apply, they do not dispute that the FDIC correctly applied the regulation to their accounts.32
[860]*860C. Whether the Prior Regulation Was Arbitrary or Capricious
30. Plaintiffs do not explicitly challenge the prior regulation’s validity. Rather, they assert that it was “too ambiguous and complex for the public to understand,” and that it was so “flawed” that the FDIC took the unusual step of implementing an interim rule before the notice and comment period.33 Despite plaintiffs’ criticisms, the court concludes that the regulation was not an arbitrary or capricious interpretation of the governing statute.
31. Courts give broad deference to an agency interpretation so long as it meets the test set forth in Chevron, U.S.A., Inc. v. Natural Resources Defense Council, Inc., 467 U.S. 837, 104 S.Ct. 2778, 81 L.Ed.2d 694 (1984). First, if the court determines that “the intent of Congress is clear, that is the end of the matter; for the court, as well as the agency, must give effect to the unambiguously expressed intent of Congress.” Chevron, 467 U.S. at 842-43, 104 S.Ct. 2778; Satterfield v. Simon & Schuster, Inc., 569 F.3d 946, 952 (9th Cir.2009). “Second, if a statute is silent or ambiguous with respect to the issue at hand, we must defer to the agency so long as the agency’s answer is based on a permissible construction of the statute.’ ” Satterfield, 569 F.3d at 952 (quoting Chevron, 467 U.S. at 843, 104 S.Ct. 2778). “An agency’s interpretation is permissible, unless it is ‘arbitrary, capricious, or manifestly contrary to the statute.’ ” Id. (quoting Chevron, 467 U.S. at 844, 104 S.Ct. 2778).
32. While Chevron concerned formal notice-and-comment rulemaking by an agency, the Supreme Court clarified in United States v. Mead Corp., 533 U.S. 218, 121 S.Ct. 2164, 150 L.Ed.2d 292 (2001), that “administrative implementation of a particular statutory provision qualifies for Chevron deference when it appears that Congress delegated authority to the agency generally to make rules carrying the force of law, and that the agency interpretation claiming deference was promulgated in the exercise of that authority.” Wilderness Society v. U.S. Fish & Wildlife Service, 353 F.3d 1051, 1060 (9th Cir.2003) (quoting Mead, 533 U.S. at 226-27, 121 S.Ct. 2164). “Delegation of such authority may be shown in a variety of ways, as by an agency’s power to engage in adjudication or notice-and-comment rulemaking, or by some other indication of a comparable congressional intent.” Mead, 533 U.S. at 227, 121 S.Ct. 2164. “Those administrative decisions not meeting these standards may still be given deference under Skidmore v. Swift & Co., 323 U.S. 134, 65 S.Ct. 161, 89 L.Ed. 124[ ] (1944).” Satterfield, 569 F.3d at 952-53.
33. Applying this test, “[t]he first step under the Chevron analysis is to determine ‘whether Congress has directly spoken to the precise question at issue.’ ” Satterfield, 569 F.3d at 953 (quoting Chevron, 467 U.S. at 842, 104 S.Ct. 2778). “If a court, employing traditional tools of statutory construction, ascertains that Congress had an intention on the precise question at issue, that intention is the law and must be given effect.” Chevron, 467 U.S. at 843 n. 9, 104 S.Ct. 2778. “It is well settled that the starting point for interpreting a statute is the language of the statute itself.” Gwaltney of Smithfield, Ltd. v. Chesapeake Bay Foundation, Inc., 484 U.S. 49, 56, 108 S.Ct. 376, 98 L.Ed.2d 306 (1987) (internal citation and quotation marks omitted). “[Unless otherwise defined, words will be interpreted as taking their ordinary, contemporary, common meaning.” Perrin v. United States, 444 U.S. 37, 42, 100 S.Ct. 311, 62 L.Ed.2d 199 (1979).
34. Congress has delegated to the FDIC the authority to make rules and regula[861]*861tions to implement the FDIA. See 12 U.S.C. § 1821(d)(1). Section 1821(a) provides that deposits maintained by a depositor in the same capacity and the same right at an insured depository institution must be aggregated and insured up to the standard maximum deposit insurance amount (“SMDIA”). The Act does not define “depositor,” “capacity,” or “right.” See 63 Fed.Reg. 25750 (May 11, 1998). Although § 1817(i)(l) provides a special rule for insurance of irrevocable trust accounts, no section of the act specifically addresses insurance of revocable trust accounts. Section 1821(a)(1)(C) requires that the FDIC “aggregate the amounts of all deposits in the insured depository institution which are maintained by a depositor in the same capacity and the same right for the benefit of the depositor either in the name of the depositor or in the name of any other person.” The statute does not provide any further definition or guidance regarding the insurance to be provided for revocable trust accounts that have multiple grantors and beneficiaries such as the ones at issue here.
35. Although Congress has mandated that FDIC promulgate rules governing the insurance of deposit accounts, it has not spoken clearly on the insurance to be provided for revocable trust accounts. Indeed, it appears that the relevant statutory provisions were enacted before revocable trust accounts became popular in the late 1980s and early 1990s. See 69 Fed.Reg. 2825 (Jan. 21, 2004). Thus, “Congress could not have spoken clearly to this issue ... when the statute was enacted.” Satterfield, 569 F.3d at 954. For all of these reasons, the court concludes that the statute is silent as to the rules governing insurance of revocable trust accounts.
36. “ ‘When a statute is ambiguous or leaves key terms undefined, a court must defer to the federal agency’s interpretation of the statute, so long as such interpretation is reasonable.’” Peck v. Cingular Wireless, LLC, 535 F.3d 1053, 1056 (9th Cir.2008) (citing Metrophanes Telecommunications, Inc. v. Global Crossing Telecommunications, Inc., 423 F.3d 1056, 1067 (9th Cir.2005)). Because the FDIA “is silent to the issue at hand, we must defer to the agency so long as the agency’s interpretation ‘is based on a permissible construction of the statute.’ ” Satterfield, 569 F.3d at 954 (quoting Chevron, 467 U.S. at 843, 104 S.Ct. 2778). The FDIC’s interpretation is permissible unless “arbitrary, capricious, or manifestly contrary to the statute.” Chevron, 467 U.S. at 844, 104 S.Ct. 2778.
37. The FDIC promulgated a regulation providing that a revocable trust account “shall be insured up to $100,000 for the prospective interest of each of the owner’s designated beneficiaries.” 63 Fed.Reg. 25752 (May 11, 1998). See also 64 Fed. Reg. 15654 (Apr. 1, 1999) (“[T]he $100,000 insurance limit is not applied on a ‘per owner’ basis. Rather, the $100,000 insurance limit is applied on a ‘per beneficiary’ basis to all [ ] accounts owned by the same person at the same insured depository institution. For instance, a [revocable trust] account owned by one person would be insured up to $500,000 if the account names five qualifying beneficiaries”). The “per beneficiary” insurance was available only for “qualifying beneficiaries.” Originally, these were spouses, children, and grandchildren. In 1999, however, the FDIC added siblings and parents as qualifying beneficiaries. Id.34
38. Where a revocable trust account is established by more than one depositor, and held for the benefit of others, some or all of whom are qualifying beneficiaries, [862]*862“the respective interests of each owner (which shall be deemed equal unless otherwise stated in the insured depository institution’s deposit account records) held for the benefit of each qualifying beneficiary [are] separately insured up to $100,000.” 63 Fed.Reg. 25761 (May 11, 1998). In other words, “[t]he amount contributed by each grantor for each ‘qualifying beneficiary’ [is] insured separately.” Advisory Opinion FDIC-05-05 at *1.
39. When a beneficiary of an account is not a qualifying beneficiary, the funds held for that beneficiary are treated as individually owned by each of the grantors, and are aggregated with other accounts owned by the grantors at the institution. Each grantor is insured for all accounts he or she owns up to $100,000. 63 Fed.Reg. 25760 (May 11,1998).
40. The FDIC recognized that “the rules governing the insurance of [revocable] trust accounts are complex and confusing.” 69 Fed.Reg. 2826 (Jan. 21, 2004). “Consequently, in response to questions about coverage of [revocable] trust accounts, the FDIC ... advise[d] depositors and bankers that they should assume that such accounts will be insured for no more than $100,000 per grantor, assuming the grant- or has no single-ownership funds in the same depository institution. Otherwise, the FDIC suggested] that the owners of living trust accounts seek advice from the attorney who prepared the trust document. Depositors who contacted] the FDIC about their living trust insurance coverage [were] often troubled to learn that they [could not] definitively determine the amount of their coverage without a legal analysis of their trust document.” Id. To ameliorate this confusion, in 2005 the FDIC issued an advisory opinion that explained in detail how a revocable trust with two grantors and multiple qualifying and non-qualifying beneficiaries would be treated. Advisory Opinion FDIC-05-05. While application of the regulation is complex, plaintiffs cite no authority for the proposition that complexity alone compels a finding that a regulation is an arbitrary or capricious interpretation of the governing statute. Moreover, the FDIC has endeavored to prevent unfair surprise by recommending that depositors seek legal advice and assume that beneficiaries are not insured, 69 Fed.Reg. 2826 (Jan. 21, 2004), and by providing a detailed explanation of the insurance treatment of revocable trust accounts with accompanying examples, Advisory Opinion FDIC-05-05.
41. The FDIC’s regulation is consistent with the purpose of the statute—to insure the deposits of all insured depository institutions, 12 U.S.C. § 1821(a)(1)(A), while simultaneously setting limits on such insurance by establishing a maximum deposit insurance amount, 12 U.S.C. § 1821(a)(1)(B), and requiring the aggregation of deposits maintained by a depositor at a single institution, 12 U.S.C. § 1821(a)(1)(C). There is no evidence that the FDIC’s interpretation was “arbitrary, capricious, or manifestly contrary to the statute.” Consequently, the court concludes it is entitled to deference.
D. The New Regulation
42. On September 30, 2008, the FDIC promulgated a new interim rule that eliminated the concept of qualifying beneficiaries. It noted that “depositors, consumer groups and bankers have questioned the fairness of limiting the coverage on revocable trust accounts to the naming of certain beneficiaries,” 73 Fed.Reg. 56708 (Sept. 30, 2008), and that eliminating the concept of qualifying beneficiaries would make “the coverage rules easier to understand. Depositors and bankers no longer need to know who is a qualifying beneficiary and who is not.... Thus, under the interim rule, the FDIC anticipates being able to [863]*863make quicker deposit insurance determinations on revocable trust accounts at institution failures.” Id.
43. Under the interim rule, a revocable trust account with an aggregate balance exceeding $500,000 and naming more than five beneficiaries is insured for the greater of $500,000, or the “aggregate amount of the ownership interests of each different beneficiary named in the trusts.” 12 C.F.R. § 330.10(e) (interim rule), 73 Fed. Reg. 56711 (Sept. 30, 2008). Because plaintiffs’ trust had eight beneficiaries, it would be entitled to insurance of $800,000, an amount exceeding the actual deposits.
44. The interim rule is “effective as of September 26, 2008 for all existing and future revocable trust accounts.” 12 C.F.R. § 330.10(i) (interim rule), 73 Fed. Reg. 56712 (Sept. 30, 2008). See also 73 Fed.Reg. 56710 (Sept. 30, 2008) (“The interim rule is effective on September 26, 2008, the date on which the FDIC Board of Directors approved the interim rule”).
E. Whether Plaintiffs’ Account Was “Existing” on September 26, 2008
45. Plaintiffs argue that “there is no legitimate dispute that Plaintiffs’ accounts existed when the revised regulation was adopted.”35
46. In a related case—Henry et al. v. FDIC, Case Nol. CV 08-05631MMM (AJWx), the court requested that the parties submit supplemental briefs addressing whether the trust accounts were “existing” as of September 26, 2008.36 The FDIC contends that the trust accounts at Indy-Mac Federal Bank are not the same accounts that plaintiffs held at IndyMac.37 It asserts that deposit accounts are insured only through a particular insured depository institution, and that, when an account is transferred to a new bank, it is not considered the same account. See 12 U.S.C. § 1821(a)(1)(A) (“The [FDIC] shall insure the deposits of all insured depository institutions as provided in this chapter”).
47. The FDIC asserts that it implements the statutory requirement that insurance determinations and payments occur “as soon as possible,” 12 U.S.C. § 1821(f)(1), by fixing a depositor’s rights “as of the day of failure,” 73 Fed.Reg. 2364 (Jan. 14, 2008). The rule the FDIC cites, although proposed prior to IndyMac’s closure, was not adopted until six days after IndyMac’s failure. 73 Fed.Reg. 41170 (July 17, 2008). The FDIC thus concedes, as it must, that the rule was not in effect as of July 11, 2008. It contends, however, that the rule embodies “the FDIC’s long-standing practice of determining a depositor’s insurance as of the date of closure.”38 Moreover, although not final as of September 26, 2008, the rule was drafted prior to that date, and provides some insight regarding the agency’s intent with respect to the treatment of existing accounts.
48. The FDIC also cites Lambert v. Federal Deposit Insurance Corp., 847 F.2d 604 (9th Cir.1988), in support of its position. Although not directly on point, Lambert describes the date on which a bank closes as the “critical date” for purposes of the FDIC’s insurance determination. Lambert examined whether a trust was revocable or irrevocable, a question which turned on which the “surviving trustor” had died as of the date of the insurance [864]*864determination. Id. at 607. Lambert, therefore, addressed the critical date for purposes of factual determinations relevant to the amount of insurance available. Here, the issue is somewhat different, i.e., what date is critical for purposes of determining the applicable law. The remaining cases cited by the FDIC similarly concern factual determinations rather than the applicability of a change in the law. Villafane-Neriz, 75 F.3d at 730 (holding that the FDIC may rely on erroneous bank records to determine whether there was an insured deposit “at the time of [the bank’s] failure”); Federal Deposit Insurance Corp. v. Liberty National Bank & Trust Co., 806 F.2d 961, 964-65 (10th Cir. 1986) (holding that “no additional rights can be created after insolvency,” but that beneficiary’s claims under standby letters of credit were provable against the FDIC as receiver despite the fact that the beneficiaries made their demand after the bank’s insolvency because the claims were fixed as of the date of insolvency); Federal Deposit Insurance Corp. v. McKnight, 769 F.2d 658, 661 (10th Cir.1985) (reviewing whether the FDIC had mistakenly paid funds on a cashier’s check, and holding that a bank’s closure “not only triggered the liquidation process, but it also cast in stone the relationship of defendants to the bank”); American National Bank of Jacksonville v. Federal Deposit Insurance Corp., 710 F.2d 1528, 1540 (11th Cir.1983) (holding that a plaintiff cannot rely on factual events that take place subsequent to a bank’s closure to support its claimed ownership of escrow funds). Plaintiffs’ case authority similarly addresses the critical date for factual determinations relevant to the insurance determination.
49. The FDIC also argues that its interpretation of the regulation is entitled to deference. “When the meaning of regulatory language is ambiguous, the agency’s interpretation of the regulation controls ‘so long as it is ‘reasonable,’ that is, so long as the interpretation sensibly conforms to the purpose and wording of the regulations.’ ” Oregon Paralyzed Veterans of America, 339 F.3d at 1131 (quoting Martin, 499 U.S. at 150-51, 111 S.Ct. 1171). See also Wards Cove, 307 F.3d at 1218 (“An agency’s interpretation of regulations it is charged with administering is entitled to a high degree of deference and will be upheld as long as it is not plainly erroneous or inconsistent with the regulation”). The court concludes that the FDIC’s interpretation of the meaning of existing account as tied to a particular depository institution is reasonable, particularly in light of the statutory mandate that the FDIC insure the “deposits of all depository institutions.” 12 U.S.C. § 1821(a)(1)(A) (emphasis added). The court is mindful that the FDIC articulated this rationale only in a legal brief at a late stage of this litigation. Because plaintiffs adduce no evidence that the term “existing account” has been applied inconsistently in other cases, because the interpretation is consistent with the FDIC’s practice of determining insurance coverage as of the date of a bank’s closure, and because the interpretation is a reasonable construction of the interim rule, the court affords the FDIC’s interpretation deference and finds that plaintiffs’ trust accounts at IndyMac were not “existing” on September 26, 2008, as that term is used in the interim rule. See Long Island Care at Home, 551 U.S. at 171, 127 S.Ct. 2339 (where an agency’s “interpretation of its own regulation reflects its considered views,” even if those views were developed in response to litigation and set forth in a legal brief, the court should accept its interpretation so long as it is not “merely a post hoc rationalization”).
F. Whether the Court Must Apply the Interim Rule Under Bradley
50. That the FDIC correctly applied the old regulation does not end the [865]*865inquiry, however. Plaintiffs argue that, notwithstanding the FDIC’s regulatory interpretation, the rule in Bradley v. School Board of City of Richmond, 416 U.S. 696, 94 S.Ct. 2006, 40 L.Ed.2d 476 (1974), mandates that “a court ... apply the law in effect at the time it renders its decision, unless doing so would result in manifest injustice or there is statutory direction or legislative history to the contrary.” Id. at 711, 94 S.Ct. 2006. See also Thorpe v. Housing Authority of Durham, 893 U.S. 268, 281, 89 S.Ct. 518, 21 L.Ed.2d 474 (1969) (“[A]n appellate court must apply the law in effect at the time it renders the decision”); DeGurules v. I.N.S., 833 F.2d 861, 863 (9th Cir.1987) (“[I]n great national concerns ... the court must decide according to existing laws, and if it be necessary to set aside a judgment, rightful when rendered, but which cannot be affirmed but in violation of law, the judgment must be set aside,” quoting United States v. Schooner Peggy, 5 U.S. (1 Cranch) 103, 110, 2 L.Ed. 49 (1801) (omission original)). Bradley emphasized that “even where the intervening law does not explicitly recite that it is to be applied to pending cases, it is to be given recognition and effect.” Bradley, 416 U.S. at 715, 94 S.Ct. 2006.39
51. Retroactive application of a rule is disfavored. Bowen v. Georgetown University Hospital, 488 U.S. 204, 208-09, 109 S.Ct. 468, 102 L.Ed.2d 493 (1988) (“Thus, congressional enactments and administrative rules will not be construed to have retroactive effect unless their language requires this result”). “Fairness concerns dictate that courts must not lightly disrupt settled expectations or alter the legal consequences of past actions.” Covey v. Hollydale Mobilehome Estates, 116 F.3d 830, 835 (9th Cir.1997). The Supreme Court in Bowen did not cite Bradley and hence created an “ ‘apparent tension’ between ‘the rule articulated in Bradley’ and the ‘generally accepted axiom’ reaffirmed in Bowen.” Gersman v. Group Health Association, Inc., 975 F.2d 886, 894-95 (D.C.Cir.1992) (quoting Kaiser Aluminum [866]*866& Chemical Corp. v. Bonjorno, 494 U.S. 827, 837, 110 S.Ct. 1570, 108 L.Ed.2d 842 (1990)).40
52. The Supreme Court reconciled Bradley and Bowen in Landgraf v. USI Film Products, 511 U.S. 244, 114 S.Ct. 1483, 128 L.Ed.2d 229 (1994). The Landgraf Court affirmed the rule in Bowen that “congressional enactments and administrative rules will not be construed to have retroactive effect unless their language requires this result.” Id. at 272, 109 S.Ct. 468 (quoting Bowen, 488 U.S. at 208, 109 S.Ct. 468). The Court noted, however, the difficulty in determining whether a statute or rule is retroactive. It observed that it was necessary to “ask whether the new provision attaches new legal consequences to events completed before its enactment. The conclusion that a particular rule operates ‘retroactively’ comes at the end of a process of judgment concerning the nature and extent of the change in the law and the degree of connection between the operation of the new rule and a relevant past event.” Id. at 269-70, 109 S.Ct. 468.41
53. Affirming Bowen’s presumption against retroactivity, the Court interpreted Bradley as an exception to the general rule. The congressional enactment applied in Bradley was a provision governing awards of attorneys’ fees in civil rights cases. Prior to its passage, federal courts were permitted to award fees based on equitable principles, as the district court in Bradley had done. “In light of the prior availability of a fee award, and the likelihood that fees would be assessed under pre-existing theories, [the Court] concluded that the new fee statute simply ‘d[id] not impose an additional or unforeseeable obligation’ on the school board.” Landgraf, 511 U.S. at 278, 114 S.Ct. 1483 (quoting Bradley, 416 U.S. at 721, 94 S.Ct. 2006).
54. In Landgraf, the Supreme Court identified three exceptions to the presumption against retroactivity. It first cited Thorpe, which held that a new agency policy requiring a local housing authority to give notice and an opportunity to respond before evicting a tenant applied to an eviction proceeding commenced before it was enacted. Thorpe, 393 U.S. 268 at 279, 89 S.Ct. 518. The Landgraf Court characterized Thorpe as a case in which the “new hearing procedures did not affect either party’s obligations,” and held that “procedural rules may often be applied in suits arising before their enactment without raising concerns about retroactivity.” Landgraf, 511 U.S. at 275-76, 114 S.Ct. 1483.
[867]*86755. In addition to procedural rules, the Court also concluded cases seeking “prospective-relief’ were not subject to the presumption against retroactivity. “When the intervening statute authorizes or affects the propriety of prospective relief, application of the new provision is not retroactive.” Id. at 273, 94 S.Ct. 2006. The Court cited American Steel Foundries v. Tri-City Central Trades Council, 257 U.S. 184, 42 S.Ct. 72, 66 L.Ed. 189 (1921), as an example of this principle. Id. There, the Court held that a section of the Clayton Act, enacted while the case was pending on appeal, governed the propriety of injunctive relief against labor picketing. Id. at 201, 42 S.Ct. 72; Landgraf, 511 U.S. at 273, 114 S.Ct. 1483. “[Bjecause relief by injunction operates in futuro and the right to it must be determined as of the time of the hearing, [the amendment] relating to injunctions was controlling in so far that decrees entered after its passage should conform to its provisions.” American Steel Foundries, 257 U.S. at 201, 42 S.Ct. 72.
56. Finally, the Court created an exception for statutes “conferring or ousting jurisdiction, whether or not jurisdiction lay when the underlying conduct occurred or when the suit was filed.” Landgraf, 511 U.S. at 274, 114 S.Ct. 1483 (citing Bruner v. United States, 343 U.S. 112, 116-17, 72 S.Ct. 581, 96 L.Ed. 786 (1952)). The Court concluded such an exception was appropriate because “[a]pplication of a new jurisdictional rule usually ‘takes away no substantive right but simply changes the tribunal that is to hear the case.’ ” Id. (quoting Hallowell v. Commons, 239 U.S. 506, 508, 36 S.Ct. 202, 60 L.Ed. 409 (1916)).
57. The Landgraf Court summarized its holding as follows:
“When a case implicates a federal statute enacted after the events in suit, the court’s first task is to determine whether Congress has expressly prescribed the statute’s proper reach. If Congress has done so, of course, there is no need to resort to judicial default rules. When, however, the statute contains no such express command, the court must determine whether the new statute would have retroactive effect, i.e., whether it would impair rights a party possessed when he acted, increase a party’s liability for past conduct, or impose new duties with respect to transactions already completed. If the statute would operate retroactively, our traditional presumption teaches that it does not govern absent clear congressional intent favoring such a result.” Id. at 280, 114 S.Ct. 1483.
58. The Ninth Circuit applied Landgraf to administrative regulations in Covey. Covey concerned the applicability of Department of Housing and Urban Development (“HUD”) regulations that defined “housing for older persons” that was exempt from the Fair Housing Act’s prohibition on familial status discrimination. Covey, 116 F.3d at 832-33. Under a rule promulgated in 1988, the exemption applied if a party adduced evidence of “the existence of significant facilities and services specifically designed to meet the physical or social needs of older persons.” Id. at 832. Because “significant facilities and services” proved difficult to interpret and implement, HUD promulgated more specific guidelines in 1995. Id. at 833. Shortly after their implementation, a district court applied the 1995 regulations and granted summary judgment for defendants in a case that had been filed in 1993. Id. at 834. Plaintiffs did not seek prospective relief and all the events at issue had occurred [868]*868prior to the effective date of the 1995 HUD regulations. Id. at 835.
59. The Ninth Circuit held that “applying the 1995 regulations retroactively simply because [plaintiffs’] claim ha[d] not yet been reduced to a judicial determination of liability would gravely undermine the presumption against retroactivity.” Id. at 837. Citing Bradley, defendants argued that the new regulations simply clarified HUD’s prior definition of the “significant facilities and services” requirement. Id. The Ninth Circuit concluded, to the contrary, that the new regulations “substantially alter[ed] the standard” for determining whether a facility could gain an exemption and declined to apply it to the dispute at hand. Id.42
60. Applying Landgraf and its Ninth Circuit progeny to the interim rule at issue in this case, the court must “first determine whether the [FDIC] expressly stated its intent to apply the new [rule] retroactively or prospectively.” TwoRivers v. Lewis, 174 F.3d 987, 993 (9th Cir. 1999) (citing Landgraf, 511 U.S. at 280, 114 S.Ct. 1483). The court has concluded, as a matter of deference to the administrative agency that promulgated the regulation, that the FDIC did not expressly state its intent to apply the statute to accounts held at depository institutions that closed prior to September 26, 2008.
61. Given that there is no “clear language directing that [the court] apply the new statute retroactively, the court next [examines] whether the new statute would have retroactive effect.” Id. (citing Landgraf, 511 U.S. at 280, 114 S.Ct. 1483). Landgraf identifies three factors that inform the court’s decision in this regard: whether the regulation “would impair rights a party possessed when he acted, increase a party’s liability for past conduct, or impose new duties with respect to transactions already completed.” Covey, 116 F.3d at 835 (quoting Landgraf, 511 U.S. at 280, 114 S.Ct. 1483). See also Landgraf, 511 U.S. at 269, 114 S.Ct. 1483 (“ ‘[E]very statute, which takes away or impairs vested rights acquired under existing laws, or creates a new obligation, imposes a new duty, or attaches a new disability, in respect to transactions or considerations already past, must be deemed retrospective,’ ” quoting Society for Propagation of the Gospel v. Wheeler, 22 F.Cas. 756, 767 (No. 13,156) (C.C.N.H. 1814) (Story, J.)); Hughes Aircraft Co. v. U.S. ex rel. Schumer, 520 U.S. 939, 947, 117 S.Ct. 1871, 138 L.Ed.2d 135 (1997) (describing each factor outlined in Landgraf and Wheeler as “a sufficient, rather than a necessary, condition for invoking the presumption against retroactivity” (emphasis original)).
62. Application of the new regulation to this case would unquestionably have retroactive effect. It would increase the FDIC’s liability for past conduct, as the FDIC would [869]*869be required to make a higher insurance payment based on a July 11, 2008 bank failure due to regulations promulgated on September 26, 2008. Because it “attaches a new disability,” namely, a significantly increased level of insurance “in respect to transactions or considerations already past [it] must be deemed retrospective.” Wheeler, 22 F.Cas. at 767. See also Covey, 116 F.3d at 835 (“Cases involving settled contract and property rights, for example, require predictability and stability and are generally inappropriate candidates for retroactivity”).43
63. “[I]f the court determines that the [regulation] operates retroactively, the traditional presumption in favor of prospectivity precludes application of the new [regulation] ‘absent clear congressional [or regulatory] intent favoring such a result.’ ” TwoRivers, 174 F.3d at 993 (quoting Landgraf, 511 U.S. at 280, 114 S.Ct. 1483). As in Covey, the court finds that the new regulations “substantially alter the standard” for determining the insurance coverage or revocable trust accounts. Covey, 116 F.3d at 837. Applying the new regulation simply because plaintiffs’ claim “has not yet been reduced to a judicial determination ... would gravely undermine the presumption against retroactivity,” particularly given the lack of a clear regulatory intent to the contrary.44
[870]*870III. CONCLUSION
For the reasons stated, the court finds that plaintiffs are not entitled to recover further insurance for their revocable trust accounts from the FDIC.
