ON PETITION FOR REHEARING
Capital Assurance Company’s Petition for Rehearing, which the United States has supported as amicus curiae, is GRANTED. We agree with the United States that the opinion published at
Capital Assurance Company, Inc. appeals the award of prejudgment interest in an insurance contract action based on a federally subsidized Standard Flood Insurance Policy it issued under Part B of the National Flood Insurance Act of 1968, 42 U.S.C. §§ 4001-4041, 4071-4129 (1994 & Supp. II 1996) (NFIA). We address, for the first time in this circuit, whether a district court violates sovereign immunity principles by awarding prejudgment interest against a so-called “Write-Your-Own” company empowered to issue flood insurance by the Federal Emergency Management Agency. We hold that it does.
*1308 I. Background
Alex W. Newton owns a vacation house on the Gulf of Mexico that is constructed on an artificially built-up point extending into the water and protected only by bulkheads. Capital Assurance Company, Inc. (Capital) sold Newton a federally subsidized Standard Flood Insurance Policy (SFIP) covering the property. The Federal Emergency Management Agency (FEMA) uses “Write-Your-Own” (WYO) companies like Capital to aid it in its statutory duty to administer the National Flood Insurance Program (NFIP). See 42 U.S.C. § 4081(a) (permitting FEMA’s Director to enter into arrangements with private insurance companies in order to make use of their “facilities and services”); 44 C.F.R. § 62.23(a)-(d) (establishing the WYO program to permit private insurers to sell and administer SFIPs). In 1995 Newton’s house and lot suffered predictable extensive flood damage from Hurricane Opal, and Newton filed a claim.
After Capital denied a portion of Newton’s claim, Newton sued in an Alabama state court. The defendants removed the case, asserting original jurisdiction under 28 U.S.C. § 1331 and 42 U.S.C. § 4053. Following a bench trial, the court awarded Newton compensatory damages, prejudgment interest, and costs. Capital appeals only the award of prejudgment interest. 1
II. Subject-Matter Jurisdiction
Although neither party has challenged the subject-matter jurisdiction of the federal courts over this suit, we are compelled to address the question sua sponte,
see, e.g., Univ. of S. Ala. v. Am. Tobacco Co.,
This leaves us only to question whether 42 U.S.C. § 4072, the provision for suits against FEMA under the NFIP as currently implemented, affects our jurisdiction. On its face, § 4072 provides only for suits against FEMA. It does not discuss the WYO program, and we therefore do not read it as addressing suits against WYO companies. It does not, therefore, abrogate § 1331 jurisdiction.

III. The No-Interest Rule
The issue Capital presents in this appeal is whether prejudgment interest awards in suits against WYO companies selling federally sponsored SFIP contracts violate the “no-interest rule,” the sovereign immunity principle that “[i]n the absence of express congressional consent to the award of interest separate from a general waiver of immunity to suit, the United States is immune from an interest award.”
Library of Congress v. Shaw,
We start our analysis by recognizing that those circuits considering the question have, for important reasons, found the no-interest rule to bar awards of interest in suits directly against FEMA.
See Sandia Oil Co. v. Beckton,
Capital urges us to accept a dictum from the Fifth Circuit that any award of prejudgment interest against a flood insurer is “a direct charge on the public treasury” indistinguishable from identical awards in suits against FEMA itself and is thus precluded by the no-interest rule.
Lee,
Even under this narrow view, however, Capital contends that the no-interest rule protects it from the award in this case because the regulations detailing the financial relationship between FEMA and WYO companies establish that interest charges against WYO companies are direct charges against FEMA. We agree. Capital begins by noting that although WYO companies initially collect premiums from which they must pay claims (including those ordered paid only as a result of litigation), and refunds, see 44 C.F.R. pt. 62, app. A, arts. 11(E), III(D)(1)-(2), 111(E), the amount of the collected premiums actually controlled by and immediately available to the WYO companies is severely curtailed by the regulations. Premiums received must be kept in separate accounts, id. app. A, art. 11(E), and all funds not required to meet current expenditures must be remitted to FEMA, id. app. A, art. VII(B). When the scant funds retained by the WYO company are not enough to satisfy outstanding claims and refunds, the WYO companies must draw upon letters of credit from FEMA. Id. app. A, art. IV(A). Because premiums collected on the policies do not belong to the WYO insurers, see id. app. A, art. VII(B), claim payments come out of FEMA’s pocket regardless of how they are paid.
Capital also points out the functionary status of the WYO companies in relation to FEMA. Under the statute, WYO companies act as the “fiscal agents of the United States,” 42 U.S.C. § 4071(a)(1); see also 44 C.F.R. § 62.23(f) (characterizing the relationship between the federal government and WYO companies as “one of a fiduciary nature” and intended to “assure that any taxpayer funds are accounted for and appropriately expended”). WYO companies may not alter the terms of SFIPs, or insert flood coverage into other policies. 44 C.F.R. § 62.23(c), (h)(6). Finally, they must adjust claims under NFIP guidelines. Id. § 62.23(i)(1).
Capital persuades us with these points— FEMA’s inevitable liability for claims and its substantial administrative oversight — to join our fellow circuits in concluding that the line between a WYO company and FEMA is too thin to matter for the purposes of federal immunities such as the no-interest rule.
See Flick v. Liberty Mut. Fire Ins. Co.,
Newton does point to countervailing considerations that might suggest that payment of claims is not a direct charge on federal funds. First, the regulations amply demonstrate that the role accorded WYO companies is in minor respects more than that of mere functionary. WYO companies may issue policies in theft own names (as Capital issued Newton’s) rather than in that of FEMA or the United States, see 44 C.F.R. § 61.13(f), and they may use theft own, individual “customary business practices”, id. § 62.23(a); see also id. § 62.23(e). For example, a WYO company may accept an application previously rejected by another WYO company. See id. § 62.23(h)(5). Similarly, WYO companies adjust claims in accordance with theft own “general [cjompany standards,” although they must seek guidance from “NFIP [c]laims manuals.” Id. § 62.23(i)(l). Finally, the regulations expressly deny that WYO companies are general agents of the government; the companies are thus “responsible for theft obligations to theft insureds under any flood insurance policies issued.” Id. § 62.23(g). WYO companies, rather than FEMA, are thus initially responsible for the “adjustment, settlement, payment and defense” of claims on the policies they sell. Id. § 62.23(d) (emphasis added). A WYO company choosing to defend against a claim must therefore seek reimbursement for its costs rather than merely handing the case over to FEMA. See id. § 62.23(f)(6) (“[D]efense costs will be part of the ... claim expense allowance.... ”). Reimbursement may be limited, moreover, if a WYO company fails to meet certain documentation requirements. See id. pt. 62, app. A, art. 111(D)(2).
But the reality lying behind these observations robs them of their strength. A WYO company may write a policy in its name, but FEMA dictates the terms. And preliminary responsibility is a mirage when the federal government, through FEMA, will always foot the full bill in the end. Giving these factors controlling weight would elevate the form of the insurance system over its substance. We thus conclude that prejudgment interest awards against WYO companies are direct charges on the public treasury forbidden by the no-interest rule and reverse the part of the judgment awarding such interest. The remainder of the judgment is unchallenged, and it is accordingly affirmed.
AFFIRMED IN PART; REVERSED IN PART.
Notes
. Capital noticed appeal of the award of costs as well, but at oral argument the parties stipulated to settlement of the costs issue.

West v. Harris,
. On this point, the Tenth Circuit has found an exception to the no-interest rule for engagement in profitable " 'commercial enterprise' ” inapplicable.
