Opinion for the Court filed by Circuit Judge TATEL.
In this case, we review a district court order enforcing two subpoenas duces tecum seeking personal financial documents issued by the Office of Thrift Supervision. We affirm the district court’s order enforcing the subpoenas with respect to two of their stated purposes: determining personal benefit and assessing ability to pay a civil penalty. Because we hold that the subpoena’s third purpose, to investigate “other wrongdoing, as yet unknown,” is invalid, we vacate the order of the district court to the extent that it enforces this purpose and remand for a revised determination of relevance.
I.
As part of its effort to stem the savings and loan crisis, Congress created the Office of Thrift Supervision (“OTS”) within the Treasury Department in the Financial Institutions Reform, Recovery and Enforcement Act of 1989, Pub.L. No. 101-73,103 Stat. 183 (codified as amended at 12 U.S.C. §§ 1441a, 1811 et seq. (1988 & Supp. V 1993)). The OTS is responsible “for the examination, safe and sound operation, and regulation of savings associations.” 12 U.S.C. § 1463(a)(1) (Supp. V 1993). Its supervisory and enforcement powers derive from the Home Owners’ Loan Act, 12 U.S.C. § 1461 et seq. (1988 & Supp. V 1993), and section 8 of the Federal Deposit Insurance Act. 12 U.S.C. § 1811 et seq. (1988 & Supp. V 1993). Authorized to conduct examinations and investigations of federally-insured savings associations, the OTS may subpoena information relevant “to any matter in respect to the affairs or ownership of any [insured depository] bank or institution or affiliate.” 12 U.S.C. § 1820(c) (Supp. V 1993); see also 12 U.S.C. §§ 1464(d)(l)(B)(v), 1818(n) (Supp. V 1993). The statutory definition of “institution-affiliated parties” in the Federal Deposit Insurance Act includes directors, officers and controlling shareholders. 12 U.S.C. § 1813(u) (Supp. V 1993). Upon discovering an insolvent thrift, the OTS may appoint the Resolution Trust Corporation (“RTC”) as receiver or conservator of the failed institution. See 12 U.S.C. § 1821(c)(6)(A) (Supp. V 1993).
In 1986, one of the appellants acquired a controlling interest in a federally-insured, state-chartered savings association (“bank”). He served as an officer and director of the bank and the other appellant served as Chairman of the Board of Directors. At the time of the acquisition of the bank, a mortgage banking business wholly owned by appellants, and the law firm of one of the appellants, made large deposits into accounts at the bank. Appellants’ control and operation of both the bank and mortgage company aroused the concern of state and federal regulators. As a result, in 1988, appellants shifted control over the daily management of the bank to a newly appointed president and Chairman of the Board of Directors. Appellants maintained their involvement as directors.
The OTS commenced a routine examination of the bank in October 1990. Discovering that the bank was nearly insolvent, it appointed the RTC as receiver in February 1991. The RTC subsequently sold the bank to another institution, effectively ending appellants’ participation in the management of the bank. The OTS investigation also included the mortgage company, which was considered an “affiliate” of the bank because one of the appellants had common control of both institutions at the time the investigation commenced.
See
12 U.S.C. § 1462(9) (Supp. Y 1993). As a mortgage servicer, the mortgage
The OTS investigation revealed an unusual practice: large overdrafts in the law firm deposit accounts were covered by overnight transfers from the mortgage company accounts and reversed the following day. According to the OTS, this practice suggested possible violations by appellants of fiduciary duties to the bank and the mortgage company and various violations of OTS regulations regarding loans to a single borrower, restrictions on loans to affiliated parties, and restrictions on overdrafts on accounts maintained by directors. See 12 C.F.R. § 563.93(d)(1) (1991); 12 C.F.R. § 563.43(b)(5) (1989); 12 U.S.C. § 375b (1988).
To pursue this irregularity, the OTS authorized a formal investigation into the affairs of the bank. On June 25, 1993, it issued an identical subpoena duces tecum to each appellant, seeking production of personal financial documents belonging to appellants, their spouses or “any entity owned or controlled by you or your spouse, or through which you or your spouse do business,” including all financial statements, tax returns, all documents relating to bank accounts or other financial investments, and any other documents relating to assets, liabilities, income and expenditures for “the period June 30, 1990, to the present date.” Joint Appendix (J.A.) at 21-22 & 33-34. It also required appellants to disclose any documents relating to transfer of assets over $1000 from “January 1, 1989, to the present date.” Id. at 22-23 & 34-35.
Appellants refused to comply with the subpoena. After several fruitless exchanges, the OTS sought enforcement in district court. The OTS claimed three purposes for the subpoena: (1) “to determine whether either of [appellants] benefitted from the use of the escrow funds to cover the overdrafts ... at the Bank,” (2) “to determine the extent of [appellants’] ability to pay civil money penalties,” and (3) to determine whether “the information may reveal other wrongdoing, as yet unknown, in the transactions [appellants] and/or their affiliated businesses had with the Bank during their tenure as owner and directors of the Bank.” Petition for Summary Enforcement of Administrative Subpoenas, Nov. 9,1993, J.A. at 55. The district court found the information sought was reasonably relevant, not unduly burdensome and within the statutory authority of the OTS. See Order to Enforce Administrative Subpoenas, Dec. 21, 1993, J.A. at 119-20.
On appeal, appellants challenge the enforcement of the subpoenas, arguing that the OTS has not yet made a determination of liability, the documents sought are not reasonably relevant to the purposes of the subpoena, and the OTS’s purpose of uncovering unknown wrongdoing is invalid. Underlying these arguments is the claim that privacy interests protected by the Fourth Amendment limit the ability of the OTS to obtain personal financial documents. On January 25, 1994, we stayed the enforcement of the subpoenas pending hearing and disposition.
II.
Our role in a subpoena enforcement proceeding is limited to determining whether “the inquiry is within the authority of the agency, the demand is not too indefinite and the information sought is reasonably relevant.”
United States v. Morton Salt Co.,
Appellants urge us to require the OTS to make a preliminary determination of liability before issuing a subpoena for personal financial information. However, nothing in
Morton Salt
or in the agency’s authorizing statutes imposes such a requirement. Indeed, the agency could not fulfill its investigative responsibilities, if, as appellants argue, it first had to make a finding of liability. If, as we have consistently stated, “an investigating agency is under no obligation to propound a narrowly focused theory of a
possible
future ease” when seeking to enforce an administrative subpoena, it certainly cannot be that the agency must make a preliminary finding of liability before it can even initiate an investigation.
Federal Trade Comm’n v. Texaco, Inc.,
While appellants insist that the personal financial nature of the subpoenaed information requires the court to alter its approach, previously we have only done so when an agency subpoenas personal information to determine cost-effectiveness. In
Walde,
we required the agency to demonstrate an “ar-ticulable suspicion” of liability before we would enforce a subpoena for personal financial information to further the agency’s stated purpose of determining cost-effectiveness.
See
The request for information relating to ability to pay civil penalties is likewise grounded in statutory authority. The OTS may assess a civil money penalty against appellants if it determines that the overnight monetary transfers resulted in a violation of banking laws or regulations or a breach of fiduciary duty. See 12 U.S.C. § 1818(i)(2)(A)-(C) (Supp. V 1993). In assessing money penalties, Congress requires the agency to consider several mitigating factors, including “the size of financial resources” of the subpoenaed party. 12 U.S.C. § 1818(i)(2)(G)(i). It is for this reason, namely, to assess the ability of appellants to pay civil money penalties, that the agency is authorized to subpoena personal financial information.
Echoing their argument regarding personal gain, appellants contend that the OTS should be required to make a preliminary determination of liability before the court enforces a subpoena for personal financial information in order to protect their Fourth Amendment privacy interests. Appellants liken the wealth-based investigation into ability to pay a civil penalty to an investigation into cost-effectiveness, but argue that the “articulable suspicion” requirement of
Walde
is not adequate to protect them. They contend that, unlike in an investigation to assess cost-effectiveness, the agency needs to know nothing at all about their wealth in
We agree that the assessment of ability to pay civil penalties is not the same as evaluating cost-effectiveness. Each arises from different statutory authority. In
Walde,
the RTC based its authority to determine cost-effectiveness on its statutory mandate to “minimize[ j the amount of any loss.realized in the resolution of eases,” 12 U.S.C. § 1441a(b)(3)(C)(iv) (Supp. V 1993), and to “conserve the assets and 'property of [the failed] institution.” 12 U.S.C. § 1821(d)(2)(B)(iv) (Supp. V 1993).
Although the investigatory purposes — cost-effectiveness and ability to pay a civil penalty — differ, an agency has no legitimate interest in seeking- personal .financial information for either purpose until it has some suspicion that the individual may be liable. Both purposes are predicated on an underlying source of liability which would call for the initiation of civil proceedings or give rise to the assessment of civil penalties. Accordingly, we hold that the
Walde
standard applies here in addition to cost-effectiveness investigations. We require the OTS to have an “articulable suspicion” that “the target [of the subpoena] engaged in wrongdoing” before it may subpoena personal financial information for the purpose of determining an individual’s ability to pay a civil penalty.
Walde,
We reject, however, appellants’ argument that we should go beyond
Walde
and require the OTS to make a preliminary determination of liability before it enforces the subpoenas in order to protect their privacy interests in personal financial documents. The constitutional concerns that arise here, which are identical to those in
Walde,
are satisfied by the application of the “articulable suspicion” standard.
See Walde,
We have no doubt that the OTS did offer sufficient information to establish an articulable suspicion of wrongdoing in this case. Its investigation was triggered by appellants’ involvement in the unusual monetary transfers between two companies that they owned within a bank that they controlled.
See
Declaration of Michael P. Moriarty, Oct. 27, 1993, J.A. at 37-42. We suggested, in
Walde,
that “records of the failed institution showing a suspicious asset transfer” would satisfy the requirement of an “articulable suspicion.”
Appellants’ final challenge to the civil penalties prong of the subpoena is that the RTC seized sufficient assets belonging to them to cover the likely amount of any penalty, and that the OTS’s investigation into their ability to pay is thus a pretext to obtain personal financial information that the agency does not need. We sought and received additional briefing regarding this allegation. In their supplemental brief, appellants estimate that the RTC is holding between $500,-000 and $1,500,000 in confiscated accounts of appellants and they assert that any potential fine would not exceed this amount. The OTS explains that the amount of the fine could be much greater: if it discovers that the violation was “knowing,” the maximum civil monetary penalty would be $1,000,000 for each day in which the conduct occurred. See 12 U.S.C. § 1818(0C2)(C), (D).
We are satisfied that the OTS will not and cannot know the appropriate amount of penalties for any statutory violations until it has completed its investigation. See 12 U.S.C. § 1818(i)(2) (requiring determination of underlying offense and accompanying mental state as well as specified mitigating factors). At this point, it is impossible to know if the funds held by the RTC would cover the entire penalty that the OTS may assess. Moreover, because the RTC may apply the monies it seized first to satisfy any claims that the RTC may bring against appellants, the funds ultimately may be unavailable to satisfy an OTS penalty.
With regard to the final purpose of the subpoenas — to uncover “other wrongdoing, as yet unknown” — we agree with appellants that the OTS offered no statutory authority to support this unlimited claim of investigatory power, nor have we discovered one. Furthermore, the broad language used to describe this purpose makes it impossible to apply the other prongs of the Morton Salt test. A reviewing court will be unable to determine whether the information demanded is “reasonably relevant” and “not too indefinite” when the agency describes its purpose as the investigation of “other wrongdoing, as yet unknown.” We thus reject this purpose as a basis for enforcing the subpoenas.
While the OTS correctly states that its investigation need not be limited to identified allegations nor a “narrowly focused theory of a
possible
future case,”
Federal Trade Comm’n v. Texaco, Inc.,
The OTS’s contention that appellants have only a limited expectation of privacy because they engaged in the highly regulated banking industry does not help it. It relies on
United States v. Miller,
in which the Supreme Court ruled that the government may subpoena a bank’s business records even when they contain information regarding an individual’s accounts without violating any constitutionally protected privacy interests.
See
III.
Having determined that the subpoenas were proper with respect to two of their stated purposes — determining personal benefit and assessing ability to pay a civil penalty — we ’ turn to appellants’ claim that the information the subpoena seeks is not relevant. We reiterated the standard for relevance in
Linde Thomson Langworthy Kohn & Van Dyke, P.C. v. Resolution Trust Corp.
to be valid, an administrative subpoena must seek information that is “reasonably relevant” to the “general purposes of the agency’s investigation.”
Given this deferential approach to the agency’s determination of relevance, we require the party challenging the investigation to bear the burden of demonstrating that the information sought is irrelevant.
See Walde,
The OTS contends that all of the information covered by the subpoenas, including both personal account information and asset transfers for the period from June 30,1990, through October 1990, is relevant to determining whether appellants received any personal benefit from the unusual pattern of overdrafts. The OTS investigation of the bank revealed suspicious monetary transfers in August, September and October of 1990. All the information requested for these three months (we deal with July below) is thus clearly relevant, as it may disclose personal benefit accruing to appellants. We affirm the district court’s enforcement of the subpoenas for these three months.
Appellants seek to cut off the investigation into their personal financial documents after February 1991 when the OTS placed the bank in receivership and effectively removed them from control of the bank. The OTS argues that its investigation must extend beyond February 1991 because it needs to determine if appellants transferred assets to hide them from an enforcement action and to assess their ability to pay a civil penalty. The district court found the information to be reasonably relevant to the agency’s investigation. Finding its decision was not clearly erroneous, we affirm.
We are unable to resolve appellants’ relevancy challenge with respect to the personal account information subpoenaed for July
IV.
For the foregoing reasons, we affirm two of the OTS’s three avowed purposes for these subpoenas. It may subpoena information to discover whether appellants benefited from the pattern of monetary transfers within the bank in order to determine whether to issue an order of prohibition. It also may seek information regarding appellants’ financial resources in order to assist in the assessment of a civil penalty because it has an “articula-ble suspicion” of wrongdoing. However, the OTS is without statutory authority to subpoena information for the general purpose of uncovering “other wrongdoing, as yet unknown.” Thus, we affirm in part and reverse in part, and remand to the district court with instructions to proceed in accordance with this opinion.
So ordered.
