BACKGROUND
We recite only those record facts essential to an understanding of the issues raised on appeal, drawing all reasonable inferences in favor of plaintiff-appellant URI. Richmond Steel, Inc. v. Puerto Rican American Ins. Co., 954 F.2d 19, 20 (1st Cir.1992). The R/V Endeavor is a vessel chartered by the National Science Foundation to URI's Graduate School of Oceanography (GSO) for research purposes. In the summer of 1985, John Metz, the GSO's port engineer, discovered serious rust corrosion on the inside of the Endeavor's steel ballast tanks, which are submerged in salt water during normal operation of the vessel. Responding to a Chesterton advertisement, Metz received test samples of "Rust Transformer," a Chesterton product which purportedly converts surface corrosion into a rust-inhibitor, which in turn serves as a base for further coats of paint. Satisfied with the test-sample results, Metz invited Chesterton sales representatives aboard the Endeavor. After inspecting the Endeavor's ballast tank corrosion, Chesterton's representatives recommended that Metz use Chesterton's 1-2-3 System (using Rust Transformer, a primer, and a final enamel coat) to rehabilitate the tanks. Metz ordered the 1-2-3 System on September 11, 1985. Six months after URI completed the 1-2-3 System application, the new coating on the ballast tanks began to loosen and flake off. URI allegedly expended $100,000 to correct the problem.
URI brought suit against Chesterton in Rhode Island state court on May 4, 1989, alleging negligence, strict liability, and breaches of an express warranty and implied warranties of merchantability and fitness for a particular purpose. Chesterton promptly removed the action to federal district court. URI moved for remand on the ground that URI, as an "alter ego, arm, or agent" of the State of Rhode Island, is not a "citizen" of Rhode Island for diversity purposes. The district court denied URI's remand motion without an evidentiary hearing, relying on an earlier district court decision, see Vanlaarhoven v. Newman, 564 F.Supp. 145 (D.R.I.1983) (Selya, J.), which determined that URI was not an "arm" of the State for sovereign immunity purposes.
This court declined to entertain URI's interlocutory appeal from the jurisdictional ruling but noted disagreement among the circuits as to the proper criteria for determining the citizenship of state universities for diversity purposes. We recommended that the district court conduct "limited factfind-ing" on remand relating to several factors pertinent to URI's citizenship, including (1) "the degree of URI's dependence on and functional integration with the state treasury," (2) "the percentage of URI's annual budget that derives from state appropriations," and (3) "whether the legislature bases levels of such appropriations in part on the amount of nonappropriated funds available to URI." On remand, the district court denied URI's motion for a pretrial evidentiary hearing relating to these jurisdictional matters. The jury trial began on December 3, 1991. After the district court excluded the testimony of URI's only expert witness on the issue of contract damages, URI abruptly rested its ease. Judgment was entered for Chesterton on all counts, as a matter of law, pursuant to Fed.R.Civ.P. 50(a), and URI appealed.
II
DISCUSSION
A. Subject Matter Jurisdiction
URI urges us to set aside the judgment and remand the case to state court on the ground that Chesterton, a Massachusetts corporation, has not established diversity. URI contends that it is not a Rhode Island "citizen," but a mere "arm" or "alter ego" of the State. See Gibbs v. Buck, 307 U.S. 66, 69, 59 S.Ct. 725, 727-28, 83 L.Ed. 1111 (1939) (holding that party invoking diversity jurisdiction must establish sufficient facts to warrant its exercise); Bank One, Texas, N.A. v. Montle, 964 F.2d 48, 50 (1st Cir.1992) (same); see also Shamrock Oil & Gas Corp. v. Sheets, 313 U.S. 100, 108-09, 61 S.Ct. 868, 872, 85 L.Ed. 1214 (1941) (removal statute should be strictly construed against removal); McNutt v. General Motors Acceptance Corp., 298 U.S. 178, 187, 56 S.Ct. 780, 784, 80 L.Ed. 1135 (1936); Wilson v. Republic Iron & Steel Co., 257 U.S. 92, 97, 42 S.Ct. 35, 37, 66 L.Ed. 144 (1921).
We begin with first principles. A State cannot be a "citizen" of itself for purposes of diversity jurisdiction. Moor v. County of Alameda, 411 U.S. 693, 717, 93 S.Ct. 1785, 1799, 36 L.Ed.2d 596 (1973); Postal Tel. Cable Co. v. Alabama, 155 U.S. 482, 487, 15 S.Ct. 192, 194, 39 L.Ed. 231 (1894). On the other hand, a political subdivision possessing the formal status of a "body politic and corporate," such as a county or municipality, is presumed a "citizen" for diversity purposes "unless it is simply 'the arm or alter ego of the State.' " Moor, 411 U.S. at 717, 721, 93 S.Ct. at 1799, 1801-02 (finding that Alameda County had a "sufficiently independent corporate character" to be a "citizen" of California for diversity purposes) (citation omitted) (emphasis in original); Illinois v. City of Milwaukee, 406 U.S. 91, 97, 92 S.Ct. 1385, 1389, 31 L.Ed.2d 712 (1972); Cowles v. Mercer County, 74 U.S. (7 Wall.) 118, 121-22, 19 L.Ed. 86 (1869). Thus, in principle at least, public and private corporations are accorded similar treatment as "citi zens" for diversity purposes. See 28 U.S.C. § 1332(c)(1) ("For purposes of this section . a corporation shall be deemed to be a citizen of any State by which it has been incorporated.... "); see also Media Duplication Servs., Ltd. v. HDG Software, Inc., 928 F.2d 1228, 1236 (1st Cir.1991).
The Rhode Island Board of Higher Education ("Board") is nominally constituted by the State of Rhode Island as the legal entity which acts in behalf of URI and other public postsecondary educational institutions in Rhode Island. The Board has been constituted a "public corporation," R.I.Gen.Laws § 16-59-1, see infra note 10, just as the County of Alameda is a "body corporate and politic" under California law. Moor, 411 U.S. at 719, 93 S.Ct. at 1801 (citing Cal.Gov't Code § 23003).
Several ancillary principles derive from Moor. The criteria are substantially similar for evaluating whether an entity is a citizen of the State for diversity purposes, or a State for Eleventh Amendment sovereign immunity purposes, see Northeast Fed. Credit Union v. Neves, 837 F.2d 531, 534 (1st Cir.1988) (tests "pretty much the same"); see supra note 4, and present the same ultimate question for decision: whether the State of Rhode Island remains the real party in interest, notwithstanding URI's designation as the nominal plaintiff. See id. at 533 ("For the purpose of diversity jurisdiction, the determinative factor is whether the state is the real party in interest.") (quoting Krisel v. Duran, 386 F.2d 179, 181 (2d Cir.1967), cert. denied, 390 U.S. 1042, 88 S.Ct. 1635, 20 L.Ed.2d 303 (1968)); see also Kovats v. Rutgers, 822 F.2d 1303, 1307 (3d Cir.1987) (immunity), cert. denied, 489 U.S. 1014, 109 S.Ct. 1126, 103 L.Ed.2d 188 (1989); Ronwin v. Shapiro, 657 F.2d 1071, 1073 (9th Cir.1981) (Board of Regents of Arizona) (immunity and diversity); Jagnandan v. Giles, 538 F.2d 1166, 1173 (5th Cir.1976) (Mississippi State University) (immunity), cert. denied, 432 U.S. 910, 97 S.Ct. 2959, 53 L.Ed.2d 1083 (1977); Krieger v. Trane Co., 765 F.Supp. 756, 757-58 (D.D.C.1991) (diversity). Thus, most unincorporated state agencies and departments are readily recognizable as mere "arms" or "alter egos" of the State.
On the other hand, though the State's formal incorporation of a State-related entity is not necessarily dispositive on the issue of its autonomy, either for immunity or diversity purposes, see, e.g., Jagnandan, 538 F.2d at 1174, 1176; Krieger, 765 F.Supp. at 760, 762, the legislative act of incorporation should prompt a thorough examination into the precise nature of the entity established under state law. See Moor, 411 U.S. at 719, 93 S.Ct. at 1800 (undertaking "a detailed examination of the relevant provisions of California law" in order to rule out Alameda County's "mere agency"); id. at 721 n. 54, 93 S.Ct. at 1801 n. 54 (generally repudiating resort to "conclusory" determinations as to entity's legal character); see also Lake Country Estates, Inc. v. Tahoe Regional Planning Agency, 440 U.S. 391, 401, 99 S.Ct. 1171, 1177, 59 L.Ed.2d 401 (1979); Mt. Healthy City Sch. Dist. Bd. of Educ. v. Doyle, 429 U.S. 274, 280, 97 S.Ct. 568, 572, 50 L.Ed.2d 471 (1977); Kovats, 822 F.2d at 1307; Goss v. San Jacinto Junior College, 588 F.2d 96, 98 (5th Cir.1979). Accordingly, comparing the incorporated public entity to the polar extremes (the State on the one hand, and political subdivisions on the other), we must determine whether the nominal public corporation possesses "a sufficiently independent corporate character to dictate that it be treated as a citizen of [the State of incorporation]." Moor, 411 U.S. at 721, 93 S.Ct. at 1802. See Mt. Healthy, 429 U.S. at 280, 97 S.Ct. at 572 (finding city board "more like a county or city than it is like an arm of the State") (emphasis added); see also Kashani v. Purdue Univ., 813 F.2d 843, 845 (7th Cir.), cert. denied, 484 U.S. 846, 108 S.Ct. 141, 98 L.Ed.2d 97 (1987); Goss, 588 F.2d at 98.
Often these comparative appraisals unavoidably lead to imprecise distinctions in degree, rarely amenable to ready resolution. Cf. Metcalf & Eddy, Inc. v. Puerto Rico Aqueduct & Sewer Auth., 991 F.2d 935, 939 (1st Cir.1993) (noting that agency's entitlement to immunity "poses an essentially functional inquiry, not easily amenable to bright-line answers or mechanical solutions") (emphasis added). Like their private counterparts, public corporations are hardly monolithic, having been vested with whatever powers, rights, and privileges state legislatures may bestow to suit the public purpose for which the particular corporation was commissioned. Although the vast majority of state universities, incorporated and unincorporated alike, have been found to be "arms" of the State for immunity and diversity purposes, each state university must be evaluated in light of its unique characteristics. See Kovats, 822 F.2d at 1303; Kashani, 813 F.2d at 845; Hall v. Medical College of Ohio, 742 F.2d 299, 302 (6th Cir.1984), cert. denied, 469 U.S. 1113, 105 S.Ct. 796, 83 L.Ed.2d 789 (1985); United Carolina Bank v. Board of Regents, 665 F.2d 553, 557 (5th Cir.1982) (Austin State University); Soni v. Board of Trustees of Univ. of Tennessee, 513 F.2d 347, 352 (6th Cir.1975), cert. denied, 426 U.S. 919, 96 S.Ct. 2623, 49 L.Ed.2d 372 (1976); University Sys. of New Hampshire v. United States Gypsum, 756 F.Supp. 640, 645 (D.N.H.1991).
We have propounded an illustrative list of criteria — by no means exhaustive— often germane to the Eleventh Amendment "arm" or "alter ego" determination, including whether the entity (1) performs an "essential" or "traditional" governmental function, as opposed to a nonessential or merely proprietary one; (2) exercises substantial autonomy over its internal operations; (3) enjoys meaningful access to, and control over, funds not appropriated from the State treasury; (4) possesses the status of a separate "public corporation"; (5) may sue and be sued in its own name; (6) can enter into contracts in its own name; (7) has been granted a state tax exemption on its property; or (8) has been expressly debarred from incurring debts in the State's name or behalf. See Metcalf & Eddy, 991 F.2d at 939-40; In re San Juan DuPont Plaza Hotel Fire Litigation, 888 F.2d 940, 942 (1st Cir.1989); Ainsworth Aristocrat Int'l Pty, Ltd. v. Tourism Co. of Puerto Rico, 818 F.2d 1034, 1038 (1st Cir.1987). These diverse considerations are designed to disclose the extent to which state law endows the incorporated State-related entity with the operational authority, discretion, and proprietary resources with which to function independently of the State. See George R. Whitten, Jr., Inc. v. State Univ. Constr. Fund, 493 F.2d 177, 180 (1st Cir.1974); cf. Metcalf & Eddy, 991 F.2d at 940 ("[T]he more tightly the agency and the state are entangled, the more probable it becomes that the agency shares the state's Eleventh Amendment immunity.").
1. The Board's Operational Autonomy
After reviewing many decisions relating to public postsecondary educational institutions, we are impressed, as was the district court in this case and in Vanlaarhoven, by the extraordinary measure of autonomy enjoyed by the Rhode Island Board of Higher Education. As with most "state" universities, the Board is charged with an essential and traditional governmental function— namely, the provision of postsecondary educational facilities to the citizens of Rhode Island. See R.I. Const. art. XII, § 1; Chang v. University of Rhode Island, 118 R.I. 631, 375 A.2d 925, 933-34 (1977); see also Kovats, 822 F.2d at 1310 (providing educational facilities is an essential or traditional governmental function, not a proprietary one); Hall, 742 F.2d at 305 (same); Rutledge v. Arizona Bd. of Regents, 660 F.2d 1345, 1349 (9th Cir.1981) (same); cf. also Kashani, 813 F.2d at 847-48 (if entity serves entire state, instead of one region, more likely an "arm" of State). As a general rule, therefore, it may well be that an entity established to conduct a core governmental function is less likely to be vested with meaningful freedom from governance by the State's elected officials. Nevertheless, this isolated factor is seldom dis-positive. An exception must he where the statutory scheme, as a whole, confutes any legislative intent to establish the entity as a mere "arm" of the State. See Kovats, 822 F.2d at 1312 (performance of governmental, nonproprietary function not necessarily indicative of lack of autonomy). Accordingly, we must examine the particular powers with which the Board is endowed under its statute of "incorporation."
From an operational standpoint, the Board is denominated a "public corporation," Moor, 411 U.S. at 719, 93 S.Ct. at 1800 (county's corporate status and powers "most notabl[e]" attributes of citizenship); cf. Hall, 742 F.2d at 305 (noting that school's lack of separate corporate status suggests mere agency), which may "sue and be sued in its own name." R.I.Gen.Laws § 16-59-1(a). The Rhode Island statutes elsewhere define the term "public corporation" as "a corporate entity which is considered a governmental agency but which has a distinct legal existence from the state or any municipality, [and] does not constitute a department of state or municipal government...." Id. § 16-62-4 (emphasis added). See Harden v. Adams, 760 F.2d 1158, 1163 (11th Cir.1985) (Troy State University) (holding that statutory definitions of "state" and "political subdivision" may be relevant factors); compare Kovats, 822 F.2d at 1310 (evidence that entity is "instrumentality," but otherwise excluded from some statutory definitions of "state," is probative of citizenship) with United Carolina Bank, 665 F.2d at 557 (noting that entity falls clearly within statutory definition of "state"). But cf. Lewis v. Midwestern State Univ., 837 F.2d 197, 198 (5th Cir.), cert. denied, 488 U.S. 849, 109 S.Ct. 129, 102 L.Ed.2d 102 (1988) (mere statutory definition as "agency" suggests "alter ego"); Kashani, 813 F.2d at 847 (holding that entity's designation as "separate" from State for some purposes is inconclusive of autonomy); Krieger, 765 F.Supp. at 759 (finding term "independent agency" inconclusive evidence of autonomy).
Ten of the thirteen Board members are appointed by the Governor, with the advice and consent of the senate, see R.I.Gen.Laws § 16-59-2(a), a legislative design most courts routinely view as evidence of an entity's lack of independence from State control. See, e.g., Lewis, 837 F.2d at 198; Kashani, 813 F.2d at 847 (7 of 10 members appointed); Harden, 760 F.2d at 1163; Hall, 742 F.2d at 306; Gay Students Servs. v. Texas A & M Univ., 737 F.2d 1317, 1333 n. 28 (5th Cir.1984), cert. denied, 471 U.S. 1001, 105 S.Ct. 1860, 85 L.Ed.2d 155 (1985); United Carolina Bank, 665 F.2d at 558; Rutledge, 660 F.2d at 1347 (all 8 appointed); Prebble v. Brodrick, 535 F.2d 605, 610 (10th Cir.1976) (University of Wyoming). But see Kovats, 822 F.2d at 1311 (concluding that, even if majority is appointed by governor, that fact is not conclusive of "alter ego" status). The power of appointment (and reappointment) is significant, and may entail risks of subtle or indirect manipulation of the entity's decision-making processes by elected officials.
On the other hand, the Rhode Island statutory scheme is somewhat unusual in the re spect that it attempts to protect the Board from "partisan or personal" pressures. R.I.Gen.Laws § 16-59-3 ("removal solely for partisan or personal reasons unrelated to capacity or fitness for the office shall be unlawful"). Although individual Board members might be vulnerable to pressure, the Board as a whole is insulated to some degree from sudden "reversal[s] of policy" by fixed (three-year) and staggered terms. Id. § 16-59-1. Cf. Jacintoport Corp. v. Greater Baton Rouge Port Comm'n, 762 F.2d 435, 442 (5th Cir.1985) (focusing on autonomy of Commission as an entity, not only on independence of the individual commissioners). Board members receive minimal compensation ($50 per day of actual service, not to exceed $3000 annually). Since it is highly unlikely that members would depend on their Board compensation as a primary source of income, the economic coercion attending the threat of removal would be minimal. R.I.Gen.Laws § 16-59-1(e). Aside from the power of appointment, the governor has no direct voice in Board decisionmaking. Cf. e.g., Fitchik v. New Jersey Transit Rail Operations, Inc., 873 F.2d 655, 663 (3d Cir.) (finding entity not "alter ego," despite gubernatorial veto power), cert. denied, 493 U.S. 850, 110 S.Ct. 148, 107 L.Ed.2d 107 (1989). Finally, and most significantly, individual Board members are provided with significant insulation from partisan or personal pressure, in that no Board member may be removed except for cause, after a full hearing and appellate review. R.I.Gen.Laws § 16-59-2, 3.
As a corporate entity, the Board's supervisory powers are pervasive. It unilaterally appoints, and may dismiss at its pleasure, the commissioner of higher education and the presidents of the individual educational institutions it oversees, see id. § 16-59-4(5), (6). It possesses plenary power over the post-secondary school organizational structure, accounting procedures, the creation and abolition of all postsecondary school departments and programs of study, as well as their affirmative action hiring practices. Id. § 16-59-4(10), (11). See Kovats, 822 F.2d at 1311-12 (finding that minimal state supervision over entity's operations suggests autonomy); cf. Hall, 742 F.2d at 306 (noting that state control through mandated programs of study suggests lack of independence); University of Tennessee v. United States Fidelity & Guar. Co., 670 F.Supp. 1379, 1384 (E.D.Tenn.1987) (observing that entity must comply with controller's regulations, and legislature controls physical plant operations). But see Kashani, 813 F.2d at 847 (finding entity's power to prescribe curricula not probative of its autonomy). The Board is expressly exempted from compliance with the Rhode Island Administrative Procedures Act, R.I.Gen. Laws § 16-59-12, see Kovats, 822 F.2d at 1312 (APA exemption suggests autonomy); cf. Fitchik, 873 F.2d at 663 (APA applicability suggests "arm"); Jackson v. Hayakawa, 682 F.2d 1344, 1350 (9th Cir.1982) (California State University) (same); Krieger, 765 F.Supp. at 760 (same), as well as from certain personnel employment and equipment requisition regulations, R.I.Gen.Laws § 16-59-21 (providing Board with exemption from R.I.Gen.Laws § 35-3-1(5), (6) in "the interest of educational efficiency"). See Kovats, 822 F.2d at 1313 (exemption from civil service rules suggests autonomy); cf. United Carolina Bank, 665 F.2d at 558 (applicability of employment regulations suggests dependence); Krieger, 765 F.Supp. at 759-60 (lack of exemption from general budget controls and procurement rules suggests "arm"); University of Tennessee, 670 F.Supp. at 1384 (legislature's control of employee compensation suggests "arm").
The Board holds full legal title to all URI real and personal property, with the attendant power to acquire, hold, and dispose of URI property and "other like property as deemed necessary for the execution of its corporate purposes." R.I.Gen.Laws § 16-59-1. See Moor, 411 U.S. at 719, 93 S.Ct. at 1800 (noting that county may "sell, hold, or otherwise deal in property"); see also Fitchik, 873 F.2d at 663 (power to purchase property suggests citizenship); cf. Hall, 742 F.2d at 306 (unlike community college which holds title to property, no independence where educational entity may sell property only with State's approval); University of Tennessee, 670 F.Supp. at 1384 (legislature's control over all physical plants and leases indicates lack of independence). Although URI's real and personal property is exempt from taxation, see R.I.Gen.Laws § 44-3-3(1); Powers v. Harvey, 81 R.I. 378, 103 A.2d 551, 552 (1954), in many eases this factor is considered minimally probative. Often, tax policy is used by States to encourage certain types of activity even though the target entities are otherwise entirely independent of state government. Rhode Island is no exception in this respect. See, e.g., R.I.Gen.Laws § 44-3-3(11) (cemeteries), (12) (incorporated or free libraries), (13) (veterans' organizations), (15) (volunteer fire departments), (21) (water treatment facilities). Moreover, nonpublic educational institutions in Rhode Island partake of a similar tax exemption, albeit narrower than that of the Board. R.I.Gen.Laws § 44-3-3(8) (private school property is tax exempt to the extent it is used "exclusively for educational purposes"). Arguably, of course, tax exemption may be attributable to the State's equitable title to the URI property. We think it at least as plausible, however, that the general assembly exempts Board property from taxation as a means of fostering performance of the Board's corporate functions. See Kovats, 822 F.2d at 1311 (autonomy not fatally undermined by tax exemption); Kashani, 813 F.2d at 846 (less probative where State grants tax exemption to political subdivisions); Hall, 742 F.2d at 307 (tax exemption relevant only if it is not accorded other entities which are not "alter egos"). But see University of Tennessee, 670 F.Supp. at 1384 (university is an "arm" because it is fully tax exempt, while private schools enjoy a partial exemption only).
As a natural corollary to its power to control URI property, the Board possesses, and freely exercises, its corporate power to enter into contracts in its own name. See State of Maryland Cent. Collection Unit v. Board of Regents, 529 A.2d 144, 145 (R.I.1987); cf. Hughes-Bechtol, 737 F.2d at 544 (lack of power to contract without invoking State as named party indicates entity is "arm"); Tradigrain, Inc. v. Mississippi State Port Auth., 701 F.2d 1131, 1133 (5th Cir.1983) (noting that authority's power to enter into contract was limited; any contract in excess of $2500 must be advertised and awarded to lowest bidder); University of Tennessee, 670 F.Supp. at 1384 (entity is "arm" where legislature exerts control over its personal services contracts). But cf. Kashani, 813 F.2d at 847 (power to enter into contracts not conclusive of independent status); Hall, 742 F.2d at 305 (same); Krieger, 765 F.Supp. at 760, 762 (same). The Board's capacity to contract for the maintenance and repair of a federally funded GSO research vessel likewise suggests operational autonomy. See Moor, 411 U.S. at 719, 93 S.Ct. at 1800 (county "may contract for the construction and repairs of structures") (emphasis added); cf. State Highway Comm'n of Wyoming v. Utah Constr. Co., 278 U.S. 194, 199, 49 S.Ct. 104, 106, 73 L.Ed. 262 (1929) (finding that entity is "arm" where "contract for the construction of the work was between the [defendant] and the State").
Thus, the Board's operational autonomy, approximating that of the political subdivision in Moor, sets it apart from most entities with similar educational missions and tips the balance in favor of the district court's finding that the Board is a "citizen" of Rhode Island for diversity purposes.

Like most other public universities, URI's operations are financed in part by State appropriations, approved annually by the general assembly ("appropriated" funds), R.I.Gen.Laws § 16-59-9 (such appropriations as the general assembly "deems necessary"), and in part by non-State sources, such as tuition charges, fees, and donations ("nonappropriated" funds). As with all state universities, the legislature has the final say as to the size of the annual appropriation. The Board, on the other hand, prepares the five-year funding plan and budget for submission to the general assembly, and the Board alone "determines priorities of expenditures." Id. § 16-59-4(4). Cf. United Carolina Bank, 665 F.2d at 558 (legislature's "comprehensive" control of appropriated funds suggests entity's financial dependence); Prebble, 535 F.2d at 610 ("No expenditure may be made in excess of an appropriation and no money appropriated may be used for any purpose other than for which it is appropriated."). Furthermore, the Board has plenary authority to reallocate appropriated funds among its various programs, facilities, and agencies. R.I.Gen.Laws § 16-59-9(c). Cf. Krieger, 765 F.Supp. at 760 (lack of power to rellocate appropriated funds suggests entity is "arm"). And, as noted, the Board has substantial income from sources other than State appropriations, see Kroll, 934 F.2d at 908 n. 3 (availability of substantial revenue from other sources may be very relevant to autonomy inquiry), including tuition charges, housing, dining and administrative fees, donations, bequests and devises, the income and proceeds from URI property, and federal grants.
URI's tuition and fees are set by the Board. URI's housing, dining, and auxiliary facilities are totally self-supporting, with no State appropriations slated for these purposes after 1987. R.I.Gen.Laws § 16-59-9(d). Thus, much of its nonappropriated funding is roughly analogous to revenues raised by means of a political subdivision's power to impose taxes upon its constituents to defray the costs of the public services it provides, a power delegated by the State to enable the political subdivision to finance its "corporate" public service mission. See Moor, 411 U.S. at 719-20, 93 S.Ct. at 1800-01 (county "authorized to levy taxes" and to "issue general obligation bonds payable from county taxes"); Metcalf & Eddy, 991 F.2d at 942 (in immunity context, "[t]he power and opportunity to generate a revenue stream [through user fees] and thereby finance an agency's operations is an important attribute of the agency's separate identity"); Fitchik, 873 F.2d at 663 (power to set and collect fares and fees tilts balance toward autonomy); see also supra note 9; cf. Kashani, 813 F.2d at 846 (lack of power to impose taxes is equivalent to ultimate financial dependence on the State); Hall, 742 F.2d at 304 (same); United Carolina Bank, 665 F.2d at 558 (same); University of Tennessee, 670 F.Supp. at 1384 (legislature's control of tuition fees suggests "arm").
There is no provision in Rhode Island law permitting State intervention in URI's income stream from inception to expenditure. The Board's nonappropriated funds are neither "covered into," nor merged with, the general fund, but are kept in segregated accounts pending discretionary disbursement by the Board "without the necessity of appropriation or reappropriation by the general assembly." R.I.Gen.Laws § 16-59-18. Compare Kovats, 822 F.2d at 1308-09 (financial accounts not "within" control of State treasury indicate autonomy), with Lewis, 837 F.2d at 197 (finding evidence of lack of au tonomy in the fact that funds must go back into State treasury, their expenditure extremely restricted); Hall, 742 F.2d at 304 (entity is an "arm" of the State if it has power to issue bonds, but disbursements of bond proceeds are restricted, and if State merely "permits" formal segregation as matter of convenience); United Carolina Bank, 665 F.2d at 558 (nonappropriated funds deposited into State treasury, then reappropriated for disbursement); Jagnandan, 538 F.2d at 1176 (nonappropriated funds go directly into commingled treasury account); Krieger, 765 F.Supp. at 760 (where entity does not "control" expenditure of funds, segregation not probative of autonomy); University of Tennessee, 670 F.Supp. at 1383-84 (all university funds commingled in one account, subject to state comptroller's regulations and "regular" audits). Unexpended balances in the Board's segregated nonap-propriated funds account are carried forward from year to year, awaiting discretionary disbursement by the Board for "nonrecurring" items, a practice which effectively allows the Board to exceed its annual appropriation and its annual budget if necessary. R.I.Gen. Laws § 16-59-9(b). Cf. Jagnandan, 538 F.2d at 1175 (lack of authority to "exceed" budgeted expenditures, even from nonappro-priated funds, without approval of executive or legislature, indicates dependency); Prebble, 535 F.2d at 610 (same).
Finally, the State of Rhode Island engages in but limited monitoring of Board revenues and expenditures, see Harden, 760 F.2d at 1163-64 (the more financial oversight, the more likely the university's debts are state's debts), though a few statutory provisions serve to keep the State generally apprised of the Board's financial decisions, enabling the type of financial monitoring usually considered indicative of a lack of meaningful fiscal autonomy. See, e.g., Lewis, 837 F.2d at 199 (regular auditing of both appropriated and nonappropriated funds suggests "arm"); Kashani 813 F.2d at 845-46 (entity is "arm" as it submits budget, and "Indiana examines [its] finances carefully"); Harden, 760 F.2d at 1163 (submission of annual financial reports suggests "arm"); United Carolina Bank, 665 F.2d at 558 ("extensive" reporting requirements suggest lack of autonomy); Rutledge, 660 F.2d at 1349-50 ("detailed" report to governor); Krieger, 765 F.Supp. at 756 (annual report to "general public" suggests "alter ego"); University of Tennessee, 670 F.Supp. at 1379 (submission of annual report to governor or legislature, with "detailed statement" of receipts and expenditures, indicates "arm"). On the other hand, the level of State fiscal monitoring of the Board is comparatively unintrusive. For example, though- URI's treasurer must submit financial reports to the state controller for "preaudit," the purely "ministerial" audit monitors Board expenditures only for possible illegality and availability of funds, not with a view to the prudence of the Board's financial decisions. R.I.Gen.Laws § 16-59-20. See Kovats, 822 F.2d at 1311 (mere "reporting" of spending decisions not indicative of lack of autonomy). URI makes a rather wan attempt to undermine Vanlaarhoven by citing a subsequently enacted "limitation" on the Board's purchasing power. See R.I.Gen.Laws § 37-2-1 and 37-2-7(11) (Board's purchases can be made only through State Purchasing agent's office). As the district court found, however, nothing in this statutory requirement portends quality review or rejection of purchase orders by the purchasing agent. R.I.Gen.Laws § 16-59-20 ("controller [shall not] interpose his or her judgment"). See supra note 7. Far from a meaningful limitation on the Board's power to disburse its funds, this measure appears to have been designed solely to enable the Board to-avail itself of the financial savings associated with pooled purchasing power.
With Moor as our benchmark, therefore, we conclude that the Rhode Island statutory scheme demonstrates that the Board, unlike more "typical" state educational entities, possesses the essential attributes of operational and financial autonomy needed to qualify as a Rhode Island "citizen" for diversity purposes.
b. "Functional Integration"
In a resourceful effort to avoid Vanlaarho-ven, URI urges its "functional integration" theory, whose genesis apparently lay in our earlier "recommendation" to the district court following dismissal of URI's interlocutory appeal. See supra p. 1202. URI ar gues, for example, that the Board's ostensible independence in financial matters would prove illusory if, in fact, (1) the Board's annual budget were funded by State-appropriated monies to such an extent that its nonappropriated revenues were rendered functionally insignificant, or (2) the Rhode Island general assembly were to employ its statutory pre-audit procedures to attune the Board's annual State appropriation so as to force the Board to expend its anticipated and accumulated nonappropriated revenues in lieu of a more ample annual State appropriation. See, e.g., Krieger, 765 F.Supp. at 761 (evidence of actual control by State would trump evidence of formal autonomy).
We emphasize that URI does not assert the existence of budgetary data which would demonstrate that the Board enjoys less financial autonomy than the enabling statute indicates. Moreover, notwithstanding its efforts to persuade the district court to conduct a separate evidentiary hearing on diversity jurisdiction, URI has taken no initiative to substantiate its "functional integration" theory, either by way of an evidentiary proffer below, or even by way of the barest allusion to supportive data in its brief or oral argument before this court. Instead, URI insists that Chesterton, as the party requesting removal, see supra Section II.A, was required to bear the entire burden of proof and production on every conceivable fact — even including "negative" facts — which might prove relevant to the Board's citizenship status. Thus, even after trial on the merits, URI speculates that there may be evidence which would preclude a reliable determination as to federal diversity jurisdiction. For the reasons hereinafter explained, we think URI inadvisably banked on a cramped view of the proper allocation of the burdens of proof and production relating to the jurisdictional issue, misapprehended the proper role of "functional integration" data, and exaggerated the import of our earlier "recommendation" to the district court for further factfinding on remand.
For some reason, our earlier invitation to engage in additional factfinding on remand went unheeded. URI intimates that it did all it could by requesting a separate evidentiary hearing, and that the district court simply discounted our recommendation as to the possible relevance of "functional integration" evidence. In our view, however, URI mis-characterizes the remand order. While we suggested the desirability of supplementary factfinding, the precise factfinding procedure to be employed always rests within the sound discretion of the trial court. See Foman v. Davis, 371 U.S. 178, 182, 83 S.Ct. 227, 230, 9 L.Ed.2d 222 (1962); O'Toole v. Arlington Trust Co., 681 F.2d 94, 98 (1st Cir.1982) (finding no abuse of discretion, as "the court was under no obligation to require an eviden-tiary hearing . [but] has the right to determine the procedures it will employ to decide a jurisdictional issue") (citation omitted). At no time did we require a separate evidentiary hearing on the jurisdictional issue. Indeed, given our alternative ground for dismissing URI's interlocutory appeal — namely, that it appeared unlikely that a trial on the merits would be prolonged — the district court's decision to defer its jurisdictional determination until trial was entirely consistent with the remand order.
Nor did the district court prevent URI from introducing any such statistical evidence at trial. Following an unrecorded pretrial conference with counsel, the district court did deny URI's motion for a separate evidentiary hearing. In that connection, URI has provided no indication of the legal contentions advanced by either party at the pretrial conference, nor of the grounds for the district court's decision to bypass a pretrial evidentiary hearing. Chesterton, on the other hand, asserts that the conference involved an extended discussion about the appropriateness of a separate pretrial hearing, but that the court opted to permit the presentation of evidence on the jurisdictional issue at trial.
Viewed in proper procedural context, therefore, the present claim hinges entirely on URI's unremitting allocation of the burdens of persuasion and production to Chesterton, and not on any lack of opportunity to raise or substantiate its "functional integration" claim. Significantly, our remand order took no position as to which party would be obliged to come forward with evidence of functional integration, nor did it suggest that proof of lack of functional integration was required in every case.
Of course, Chesterton, the party invoking diversity jurisdiction, bears the ultimate burden of proving diversity of citizenship. See Topp v. Compair, Inc., 814 F.2d 830, 839 (1st Cir.1987). Nevertheless, there is more to be said concerning the burden of production:
[T]he party who invoked diversity jurisdiction has the burden of proving all facts upon which jurisdiction could be sustained. If [the invoking party] does construct a prima facie showing of diversity, [the challenging party] must overcome or rebut this showing in order to dismiss the [removal petition]. Support for [the challenger's] position may be derived from affidavits, depositions, and sworn statements filed by the parties from which the Court can examine and evaluate all relevant factors and surrounding circumstances but the exact method of determining the jurisdictional issue lies within the sound discretion of the district court.
United States Fidelity & Guar. Co. v. Di Massa, 561 F.Supp. 348, 350 (E.D.Pa.1983) (citation omitted). Although neither Chesterton nor URI submitted affidavits, depositions, or sworn statements, the district court properly conducted inquiry into the controlling jurisdictional facts, pursuant to Moor, by examining the Rhode Island enabling statute. Under Moor, such an inquiry is designed primarily to provide the court with a competent basis for determining the legal framework within which the relationship between a State and a State-created entity are required to function. In the present case, the Rhode Island enabling statute constituted a sufficient proffer on the issue of the Board's financial autonomy. See, e.g., Tradigrain, 701 F.2d at 1132 ("the state's constitutional, statutory, and decisional law" comprise source material for the court's citizenship analysis); see also Indiana Port Comm'n v. Bethlehem Steel Corp., 702 F.2d 107, 109 (7th Cir.1983); cf. supra note 8.
As noted, see supra Section II.A.2.a, the enabling statute's broad grant of control to the Board over nonappropriated revenues weighs heavily in Chesterton's favor and satisfied its prima facie burden on the issue of financial autonomy. Furthermore, financial autonomy is but one component of the fact-intensive citizenship inquiry mandated by Moor, and Chesterton prevailed on most other relevant jurisdictional facts as well. See supra Section II.A.1. It was incumbent on URI, therefore, to mount an effective challenge to the prima facie showing of financial autonomy. See Ohio Nat'l. Life Ins. Co. v. United States, 922 F.2d 320, 327 n. 7 (6th Cir.1990) ("That the burden of proof is always on the [party asserting jurisdiction] does not mean that a [challenger], without any proof on his part, can put the [party asserting jurisdiction] to proof by affidavit of jurisdictional facts sufficiently alleged in the complaint. The [challenger] must at least submit some proof that the jurisdictional facts so alleged do not exist.") (citation omitted) (emphasis added). Absent evidence or a compelling argument that the fiscal autonomy permitted the Board under Rhode Island law, as determined by the district court, does not actually obtain, URI failed to overcome Chesterton's prima facie showing.
Furthermore, challenges to subject matter jurisdiction typically arise early in the litigation, and even though Eleventh Amendment immunity and diversity jurisdiction may require fact-intensive inquiries, see Kroll, 934 F.2d at 908 n. 2, we see no justification for requiring the removing party to resort to formal discovery before the opposing party— with readier access to the evidence — raises a specific dispute relating to a duly alleged jurisdictional fact. Such a requirement would invite needless waste of judicial resources on a threshold issue which must be resolved as expeditiously as practicable. See Tanzymore v. Bethlehem Steel Corp., 457 F.2d 1320, 1323 (3d Cir.1972) (no need for evidentiary hearing on jurisdictional question if no facts are in genuine dispute).
Without statistical evidence, URI's rebuttal was exceedingly thin. Nevertheless, because it is clear that the Board is "dependent" on the State for some unknown portion of its revenues, we will assume, arguendo, that certain provisions of the enabling statute cited by URI did give rise to a genuine dispute over an important jurisdictional fact — whether the Board actually enjoys financial autonomy from the State. See, e.g., R.I.Gen.Laws § 16-59-5 (Board must hold annual meeting to discuss budget and "invite" members of general assembly); id. § 16-59-9(c) (all proposals for tuition increases must be made before State appropriates funds for fiscal year).
As far as we can discern from the case law, in only three situations has the financial autonomy authorized by an enabling statute been considered illusory. First, "functional integration" may obtain if the State nonetheless bears the ultimate legal responsibility to answer for debts on which the state university defaults. Thus, the very financial independence accorded the Board under the Rhode Island enabling statute ultimately might expose the State treasury to liability for the Board's financial obligations. In Kovats, 822 F.2d at 1309, the Third Circuit flatly rejected such a functional integration claim where the legislature's decision to answer for the university's debts appeared to be purely discretionary and not legally binding. Cf. also Fitchik, 873 F.2d at 661 (the State's disclaimer of any obligation to "cover" is the primary consideration, not the relative size (50-70%) of the state appropriation); but cf. Hall, 742 F.2d at 304-05 (no statute prohibits university from incurring debt in state's name, and fact that state will have to "cover" debt by law is indicative of "alter ego" status); Krieger, 765 F.Supp. at 761 (where District of Columbia expressly committed itself to funding, agency not wholly "self-supporting" is "mere arm").
Even if a state's ultimate legal obligation to "cover" a university's financial obligations were the controlling consideration in the diversity context, however, but see Moor, 411 U.S. at 719, 93 S.Ct. at 1800 (noting that the county, "and from all that appears the county alone, is liable for the judgments against it") (emphasis added), the Rhode Island statutory scheme evinces no conclusive answer as to whether the State is so obligated. We have neither been cited to, cf. supra note 8, nor have we found, statutory language governing whether the State of Rhode Island ultimately is responsible for the Board's corporate financial obligations. Cf. Metcalf & Eddy, 991 F.2d at 940 (statute explicitly divested Puerto Rico Aqueduct and Sewer Authority of power "to pledge the credit or taxing power of the Commonwealth," thereby "erectfing] a wall between the agency's appetite and the public fisc.").
Second, the amount of the Board's nonap-propriated funding, either in absolute or relative terms, might be considered so insubstantial as to leave the Board financially dependent on the State. But even assuming, ar-guendo, that an entity receiving any State funding or subsidy is thereby inevitably rendered susceptible to State pressure, two principles remain constant. First, an incorporated entity dependent entirely on State appropriations rarely (if ever) would escape characterization as the State's "alter ego," since the hand that holds all the purse strings presumably controls the dependent entity. See, e.g., State Highway Comm'n, 278 U.S. at 199, 49 S.Ct. at 106 (finding no diversity where Highway Commission, de spite its power to sue and be sued, "had no funds or ability to respond in damages"); Neves, 837 F.2d at 584 (where monies "will inure exclusively to the benefit of the public fisc," the diversity inquiry is at an end); Culebras Enters. Corp. v. Rios, 813 F.2d 506, 517 (1st Cir.1987) (Puerto Rico conservation authority is "alter ego" notwithstanding its power to sue and be sued, where agency directors attested, and plaintiffs did not dispute, that "the agency would not have the funds to satisfy a judgment and that such would have to be satisfied from the general budget of [Puerto Rico]"); see also Kashani, 813 F.2d at 846 (lack of other funding "ensures ultimate fiscal reliance on state"); Gay Students Servs., 737 F.2d at 1333 n. 28 (same); Hughes-Bechtol, 737 F.2d at 543 ("board has no funds or ability to respond in damages"); Ronwin, 657 F.2d at 1073 (given State's comprehensive provisions for risk management, "no evidence that the Board, acting in its corporate capacity, could satisfy a libel judgment in any way other than by turning to the state of Arizona"). URI must concede that the Board does not . fall within this bright-line category.
On the other hand, mere receipt of state appropriations is not conclusive evidence of the recipient entity's "alter ego" status. Many (if not most) political subdivisions routinely receive significant state appropriations, but are characterized as autonomous entities for immunity and diversity purposes. See, e.g., Mount Healthy, 429 U.S. at 280-81, 97 S.Ct. at 572-73 (city board of education, which received "significant amount" of state funding, not entitled to immunity where State granted board the power to raise its own revenue); Gary A. v. New Trier High Sch. Dist., 796 F.2d 940, 945 (7th Cir.1986) (noting that the "fact that a local school district receives 'a significant amount of money from the state' does not mean that it is an arm of the state") (emphasis added) (citation omitted). In the Eleventh Amendment immunity context, we recently rejected just such a contention:
We think [that the Puerto .Rico Aqueduct and Sewer Authority's] situation is not unlike that of a typical political subdivision. Such an entity often receives part of its budget from the state and raises the rest independently. Despite this dual funding, such entities do not automatically (or even usually) come within the zone of protection demarcated by the Eleventh Amendment . despite the "significant amount of money" [they] received from the state.
Metcalf & Eddy, 991 F.2d at 941 (citations omitted).
Nevertheless, under Moor, the courts are expected to consider available statistical evidence in arriving at a more precise assessment of the relative "significance" of the appropriated and nonappropriated funding which goes into the university budget. See Kovats, 822 F.2d at 1308 (entity is "citizen" even though state appropriation is "large," or approximately 50 to 70% of budget). But see Kashani, 813 F.2d at 845 (33% appropriation suggests "arm"); Hall, 742 F.2d at 304 (average 64% state appropriation suggests "arm"); Jagnandan, 538 F.2d at 1175 (maximum 72% state appropriation suggests "alter ego"). In the present case, however, neither the amount nor the percentage of the Board's nonappropriated revenues can be ascertained from the record. Thus, argues URI, the district court was compelled to find that Chesterton did not sustain its burden of proof on the Board's financial autonomy.
In characterizing such statistical data as indispensable jurisdictional "facts," however, URI misconstrues our ease law, as well as Supreme Court precedent. We have never intimated that such statistical information is itself a jurisdictional fact, the absence of which would invariably defeat diversity jurisdiction. The core jurisdictional fact, after all, is financial autonomy. Under the seminal Supreme Court decisions dealing with both immunity and diversity, there is a noticeable lack of reliance on such statistical data, a fact which confutes its indispensability. See, e.g., Mount Healthy, 429 U.S. at 280-81, 97 S.Ct. at 572-73 (noting only "significant amount of money" received from State) (emphasis added); Moor, 411 U.S. at 719-20, 93 S.Ct. at 1800-01 (discussing county's ability to raise its own funds, not whether county received any funds from State); see also Metcalf & Eddy, 991 F.2d at 938. Unsurprisingly, as the divergent conclusions reached on essentially similar "statistical" evidence suggest, see supra p. 1215, a closely calibrated "statistical" approach in these cases entails its own impediments to reliable decisionmaking; namely, at what levels should the absolute or relative size of an entity's appropriated funding be considered so substantial, or its no-nappropriated funding so insubstantial, that "functional integration" is to be presumed, or a previous judicial determination of the entity's citizenship set aside? We believe a wide margin of variance would need to be demonstrated before it could be found to have effected a sea change in the entity's jurisdictional status. After all, while not immutable, the citizenship of a public corporation, like its domicile, should be accorded a reasonable measure of permanence; at the very least, ordinary fluctuations in the university's budget ought not occasion continual judicial reevaluation. Thus, trial court rulings on subject matter jurisdiction normally ought not await budgetary data and oscillations absent an evidentiary proffer of sufficient import to alter a determination based on an analysis of state statutory and decisional law. In our view, this approach best comports with the analysis contemplated in Moor.
In considering whether Chesterton carried its burden of persuasion on the issue of financial autonomy, we think it is inescapable that the Board's nonappropriated revenues represent a substantial budget component; tuition, housing, dining and administrative fees, donations, bequests, federal grants, and the proceeds from discretionary sales and leases of URI property are not insubstantial revenue sources. Thus, on its face, the enabling statute demonstrates Board access to, and control over, substantial amounts of no-nappropriated revenues. Following a trial on the merits, and absent any indication that URI did not have a fair opportunity to identify and produce statistical evidence which might rebut Chesterton's demonstration that the enabling statute confers the requisite financial autonomy to qualify the Board for citizenship under Moor, we conclude that URI's appellate challenge comes too late.
Finally, in a similar vein, URI suggests that it might be that the State routinely attunes its annual appropriation to the Board in response to the total amount of nonappro-priated funds available to the Board, including the nonappropriated funds accumulated from prior fiscal years and those anticipated in the current fiscal year. Under this "linkage" theory, the State could compel the Board to expend all accumulated and anticipated nonappropriated funds merely by limiting its annual appropriations to the difference between the Board's fiscal year revenue requirements and the total available nonap-propriated funds.
URI's contention that the State might link its appropriations to the availability of nonap-propriated Board funds is pure conjecture. Arrayed against URI's conjecture are the explicit provisions of the enabling statute, as amended in 1988, which expressly state that all nonappropriated funds, including accumulated nonappropriated funds, are to be deposited in a segregated account under the exclusive control of the Board. See Kovats, 822 F.2d at 1308-09 (mere possibility of offset by state appropriations not especially probative of "alter ego" status). Appropriated funds, on the other hand, are to be set apart in a separate account, and all unexpended balances in the appropriated, funds account are to be redeposited to the general fund. Unexpended nonappropriated funds, however, are carried over from year to year in the Board's nonappropriated funds account. This separate treatment of appropriated and nonappropriated funds, deliberately mandated by the general assembly, would have been both superfluous and contraindicated had routine "linkage" been intended. Cf. Allende v. Shultz, 845 F.2d 1111, 1117 (1st Cir.1988) (in general, courts should avoid interpretations which would render a statutory provision meaningless). In the absence of any countervailing showing, the Board's financial autonomy, as ordained by the general assembly in the enabling statute, was sufficient to sustain Chesterton's burden of proof on the central jurisdictional fact at issue under 28 U.S.C. § 1332.
Accordingly, having weighed the myriad factors contemplated by Moor, we conclude that the district court correctly determined that Chesterton met its ultimate burden of establishing that the Board enjoys "a sufficiently independent corporate character to dictate that it be treated as a citizen of [Rhode Island]." Moor, 411 U.S. at 721, 93 S.Ct. at 1802.
B. Evidence of Damages
In a ruling that proved fatal to URI's claims for damages for breach of warranties, the district court excluded the testimony of URI's longtime controller, Ronald Osborne, a certified public accountant in charge of all URI financial information and accounting practices. URI called Osborne as an expert witness to establish the amount of money it spent to correct the corrosion problem allegedly left unremedied by Chesterton's 1-2-3 System. URI proffered no other evidence on damages. Osborne testified on direct examination that he previously had performed cost assessments on various URI projects, and that his usual procedure was to consult URI financial records and conduct interviews with URI personnel involved in the particular project. He consulted GSO records to ascertain the overtime hours worked in 1985, and conducted several interviews with URI employees and various "private vendors" to ascertain which overtime hours were attributable to the correction of Endeavor's corrosion problem. To these figures he added the cost of fringe benefits (22%) for overtime employees, and "indirect costs," at an unspecified percentage rate, which included expenses for "accounting, purchasing, maintenance, [and] utilities." Before Osborne could state an opinion concerning the total monetary damages sustained by URI, Chesterton objected on the grounds that (1) Osborne was not a qualified expert on damages calculation, (2) the factual bases for his calculation included inadmissible hearsay, and (3) the damages calculation included inappropriate factors, such as "indirect costs."
URI relied on Federal Rules of Evidence 703 and 705 as grounds for the admission of Osborne's expert opinion. Rule 703 provides that "[t]he facts or data . upon which an expert bases an opinion or inference . [,] [i]f of a type reasonably relied upon by experts in the particular field in forming opinions or inferences upon the subject, . need not be admissible in evidence." Fed.R.Evid. 703. Rule 705 provides that "[t]he expert may testify in terms of opinion or inference and give reasons therefor without prior disclosure of the underlying facts or data, unless the court requires otherwise. The expert may in any event be required to disclose the underlying facts or data on cross-examination." Fed.R.Evid. 705 (emphasis added). The court sustained Chesterton's objection on the ground that URI had not demonstrated that the facts relied on by Osborne were of a type reasonably relied on by experts in damages assessment.
URI's central arguments on appeal are: (1) Rules 703 and 705 afford the right to present unsubstantiated expert testimony on direct examination without first disclosing its factual underpinnings, and (2) the district court abused its discretion by adhering to its self-imposed rule of exclusion, a per se rule which, according to URI, runs counter to the "burden shifting" implicit in Rule 705 and disregards the obligation to predicate its exclusionary ruling on the particular circumstances.
We have no doubt that Rules 703 and 705 permitted the district court to admit Osborne's opinion testimony, see International Adhesive Coating Co. v. Bolton Emerson Int'l, 851 F.2d 540, 545 (1st Cir.1988) (business and financial records are "obvious" sources relied on by accountants in ascertaining damages), subject of course to Chesterton's right to probe the premises of the opinion on cross-examination. But that is not the question presented. Rather, the issue on appeal is whether the district court abused its considerable discretion by excluding the evidence. We think not.
Rules 703 and 705 normally relieve the proponent of expert testimony from engaging in the awkward art of hypothetical questioning, which involves the somewhat meticulous, and often tedious, process of laying a full factual foundation prior to asking the expert to state an opinion. In the interests of efficiency, the Federal Rules of Evidence deliberately shift the burden to the cross-examiner to ferret out whatever empirical deficiencies may lurk in the expert opinion. Nevertheless, Rules 703 and 705 do not afford automatic entitlements to proponents of expert testimony. Rule 703 requires the trial court to give "careful consideration" to any inadmissible facts upon which the expert will rely, in order to determine whether reliance is "reasonable." Id. at 545. Similarly, under the broad exception to Rule 705 ("unless the court otherwise requires"), the trial court is given considerable latitude over the order in which evidence will be presented to the jury. See Fed.R.Evid. 705 advisory committee's note ("[Sjafeguards [to minimize 'unfair' burden on cross-examiner] are reinforced by the discretionary power of the judge to require preliminary disclosure in any event.") (emphasis added). While the trial court's discretion is not unfettered, at a minimum the rules suggest that the proponent must be prepared, if the court so requires, to make a limited offer of proof to aid the court in its assessment. Cf. Ambrosini v. Labarraque, 966 F.2d 1464, 1469 (D.C.Cir.1992) ("A court must know the basis for an expert's opinion before it can determine that the basis is not of a type reasonably relied on by experts in the field."); Head v. Lithonia Corp., 881 F.2d 941, 944 (10th Cir.1989) (despite the liberality of Rule 703, court must not abdicate its responsibility to assure "minimum standards" for admissibility as required by Rule 104(a)).
Even though URI's threshold burden was minimal, and may have been readily met, it made no attempt whatever to assuage the district court's legitimate concerns, but chose instead to rely on its perceived "right" to have Osborne's opinion admitted under Rule 703. Apparently, URI came to trial with no supporting documentation whatever to substantiate Osborne's assessment of damages. Based on what can be gleaned from Osborne's preliminary testimony, URI's apparent unpreparedness and recalcitrance may have given the district court real concerns as to Osborne's methodology. Unlike the expert witness in International Adhesive, Osborne's "damages" assessment was not based solely on the conventional examination and compilation of documents from which an expert objectively might ascertain the overtime labor costs incurred in repairing Endeavor's ballast tanks, as distinguished from various other projects at URI and the GSO. Rather, Osborne relied on "interviews" with undisclosed URI employees and "outside vendors," conducted either by himself or other URI officials who reported to him. The trial court quite reasonably expected URI to explain, out of the presence of the jury, the basic assumptions undergirding its witness's seemingly unorthodox method of reconstruction.
Rather than provide an explanation, however, URI simply accepted a directed verdict on the issue of damages. Moreover, when pressed by the district court, URI indicated no inclination to pursue a claim for nominal damages. Although we are given some pause by the district court's blanket statement that it "always requires" the proponent to disclose on direct examination the factual basis for an expert opinion, cf. e.g., Lis v. Robert Packer Hosp., 579 F.2d 819, 822, 822-23 (3d Cir.) (expressing disapproval of trial court's statement that it invariably exercises its discretion to invoke the Rule 611(b) exception), cert. denied, 439 U.S. 955, 99 S.Ct. 354, 58 L.Ed.2d 346 (1978), there was no abuse of the court's broad discretion in this case, as a sound basis existed for requiring disclosure.
III
CONCLUSION
We need proceed no further with this endeavor. Absent competent evidence of damages, the district court properly granted judgment as a matter of law in favor of Chesterton on URI's breach of warranty claims.
The judgment of the district court is affirmed.
. The original URI complaint alleged that Metz was reassured by Chesterton that the 1-2-3 System would work on Endeavor's ballast tanks. On the other hand, the product's written instructions advised that the system was not recommended for surfaces regularly immersed in sea water. In an amended complaint, URI alleged that Chesterton representatives observed the URI crew applying the 1-2-3 System to the ballast tanks, but said nothing to URI representatives about the unsuitability of the system or its improper application.
.As an alternate and independent reason for declining to entertain the interlocutory appeal, this court noted that the litigation was unlikely to be so protracted as to warrant appellate interruption, given the nature and scope of URI's contract claims.
. Section 1332(a) provides that "[t]he district courts shall have original jurisdiction of all civil actions . [involving over $50,000] . between . citizens of different States...." 28 U.S.C. § 1332(a)(1).
. A political subdivision's "detachment" from the State generally will deprive it of the right to partake of the State's sovereign immunity under the Eleventh Amendment. See U.S. Const. amend. XI ("The judicial power of the United States shall not be construed to extend to any suit in law or equity, commenced or prosecuted against one of the United States by citizens of another state...."). Although we have noted the essential similarity between the immunity and diversity tests, see George R. Whitten, Jr. Inc. v. State Univ. Constr. Fund, 493 F.2d 177, 179 n. 2 (1st Cir.1974) (tests "closely allied and yet not identical"); cf. Krieger v. Trane Co., 765 F.Supp. 756, 758 (D.D.C.1991) (rejecting any distinction between the two tests), we have not had occasion to identify the precise nature of any differences. In this case, however, we address, and reject, two proposed distinctions. First, Eleventh Amendment analysis normally would focus primary attention on any financial drain on the State treasury caused by a judgment adverse to URI, see Quern v. Jordan, 440 U.S. 332, 337, 99 S.Ct. 1139, 1143, 59 L.Ed.2d 358 (1979); Edelman v. Jordan, 415 U.S. 651, 663, 94 S.Ct. 1347, 1355-56, 39 L.Ed.2d 662 (1974), a concern which obviously does not arise in a diversity case where the State-related plaintiff seeks to recover a monetary judgment. Significantly, however, courts have not accepted the notion that sovereign immunity exists only if the State treasury is threatened. See Cory v. White, 457 U.S. 85, 90-91, 102 S.Ct. 2325, 2328-29, 72 L.Ed.2d 694 (1982); Kroll v. Board of Trustees of Univ. of Illinois, 934 F.2d 904, 908 (7th Cir.), cert. denied, - U.S. -, 112 S.Ct. 377, 116 L.Ed.2d 329 (1991); Harden v. Adams, 760 F.2d 1158, 1163 (11th Cir.) (Troy State University), cert. denied, 474 U.S. 1007, 106 S.Ct. 530, 88 L.Ed.2d 462 (1985). Whether in the diversity or the immunity context, the analysis must center on the State-related party's enduring legal identity as a juridical entity separate from the State.
The second possible distinction we must consider is that, unlike sovereign immunity, nondi-versity cannot be waived by the State. See State Highway Comm'n of Wyoming v. Utah Constr. Co., 278 U.S. 194, 199, 49 S.Ct 104, 105-06, 73 L.Ed. 262 (1929); George R. Whitten, Jr., Inc., 493 F.2d at 179. Generally, however, the "waiver of immunity" inquiry would follow the initial determination that the State-related entity was not sufficiently autonomous to escape characterization as an "alter ego" of the State. For example, in Vanlaarhoven, the court based its holding on the alternate ground that, even if URI were merely an "alter ego" of the State, the State had expressly waived URI's immunity under state law by granting it the authority to "sue or be sued " in its own name. Vanlaarhoven, 564 F.Supp. at 149; see also infra note 7. While such a bypass argument is impermissible where the sole issue is URI's citizenship for diversity purposes, sovereign immunity case law, and its identification of the relevant attributes of autonomy, is no less probative in diversity cases; hence, we cite to these cases as apposite.
. The complaint mistakenly designates URI as the plaintiff. Since URI is not a distinct legal entity under Rhode Island law, we treat the Board as the real party in interest, as did the district court.
. Section 16-59-1 (a) provides, in pertinent part: "There is hereby created a board of governors for higher education, sometimes hereinafter referred to as the 'board' or the 'board of governors,' which shall be and hereby is constituted a public corporation, empowered to sue and be sued in its own name, to have a corporate seal, and to exercise all the powers, in addition to those hereinafter specifically enumerated, usually appertaining to public corporations entrusted with control of postsecondary educational institutions and functions." R.I.Gen.Laws § 16-59-1(a) (1992). In all significant respects, this section, enacted in 1988, merely extended the extant powers possessed by the Board's immediate predecessor, the entity involved in Vanlaarhoven.
. Even if it were presumed that the immunity and diversity standards converge, see supra note 4, Vanlaarhoven was not conclusive as to URI's citizenship for diversity purposes. Chesterton argues that URI is barred, by Vanlaarhoven and collateral estoppel, from litigating the diversity jurisdiction issue. We do not agree. Chesterton did not raise the estoppel issue in the district court, nor did the court invoke collateral estop-pel by way of reference to Vanlaarhoven. Thus, Chesterton waived the issue. McCoy v. Massachusetts Inst. of Technology, 950 F.2d 13, 22 (1st Cir.1991), cert. denied, - U.S. -, 112 S.Ct. 1939, 118 L.Ed.2d 545 (1992) (issues not "squarely" raised before trial court cannot be raised on appeal). Moreover, the "alter ego" determination in Vanlaarhoven was not "essential" to the judgment, in at least two respects. See Restatement (Second) of Judgments § 27 ("When an issue of fact or law is actually litigated by a valid and final judgment, and the determination is essential to the judgment, the determination is conclusive....") (emphasis added). First, the Vanlaarhoven court, as an alternate holding, assumed arguendo that URI might be an "alter ego" of the State, but went on to hold that Rhode Island law had recognized similar grants of the power to sue and be sued as express waivers by the State of an alter ego's sovereign immunity from unconsented suit. Vanlaarhoven, 564 F.Supp. at 149; see supra note 4. Second, URI, the defendant in Vanlaarhoven, prevailed on the merits. Except in limited circumstances not present here, the party that prevails on the merits is not obligated to appeal from an adverse ruling on a collateral issue. Cf. Deposit Guar. Nat'l Bank v. Roper, 445 U.S. 326, 334-35, 100 S.Ct. 1166, 1172, 63 L.Ed.2d 427 (1980) (noting that adverse ruling presumably would have no effect in later litigation).
Although not binding, Vanlaarhoven nonetheless remains persuasive precedent in its own right. See Metcalf & Eddy, 991 F.2d at 940 n. 4 (noting that immunity of agency need not always be considered de novo; "[wjhere the agency's activity and its relation to the state remain essentially the same, prior circuit precedent will be controlling") (emphasis added); see also infra note 16. URI argues that much of Vanlaarho-ven 's precedential weight was eroded by the later repeal of R.I.Gen. Laws § 16-31-1 to 15 in 1988, and its replacement with the new statutory scheme. See R.I.Gen. Laws § 16-59-1. We agree with the district court that the legislative modifications in 1988 were largely inconsequential, see infra Section II.A.2.a" and that Vanlaar-hoven s "lengthy description of the fiscal relationship between the University and the State of Rhode Island is as accurate today as when it was written in 1983...." University of Rhode Island v. A.W. Chesterton Co., 721 F.Supp. 400, 402 (D.R.I.1989).
. URI argues that Rhode Island case law provides a definitive statement on the functional interdependence of the Board and the State. See, e.g., State of Maryland Cent. Collection Unit v. Board of Regents, 529 A.2d 144, 145 (R.I.1987); Opinion to the Governor, 94 R.I. 464, 181 A.2d 618 (1962). State court decisions are entitled to great deference in our diversity and sovereign immunity determination. See Ainsworth, 818 F.2d at 1037; see also Harden, 760 F.2d at 1163; Jackson v. Hayakawa, 682 F.2d 1344, 1350 (9th Cir.1982) (California State University); Jagnandan, 538 F.2d at 1175-76; Brennan v. University of Kansas, 451 F.2d 1287, 1290 (10th Cir.1971). But see Kovats, 822 F.2d at 1310 (state case law treating entity as "arm" does not undermine autonomy for diversity purposes). Nevertheless, the "real party in interest" analysis is ultimately a matter of federal law. See Moor, 411 U.S. at 720, 93 S.Ct. at 1801 (looking to California state court decisions merely to confirm Court's independent diversity determination, based on California statutes); Hughes-Bechtol, Inc. v. West Va. Bd. of Regents, 737 F.2d 540, 543 (6th Cir.) (diversity), cert. denied, 469 U.S. 1018, 105 S.Ct. 433, 83 L.Ed.2d 359 (1984); Long v. Richardson, 525 F.2d 74, 79 (6th Cir.1975) (Memphis State University); cf. Jacintoport Corp. v. Greater Baton Rouge Port Comm'n, 762 F.2d 435, 439 (5th Cir.1985).
In the instant case, we find the State of Maryland and its predecessor decisions inconclusive. First, State of Maryland involved the distinct question of the United States Supreme Court's original jurisdiction, not the issue of diversity jurisdiction. State of Maryland, 529 A.2d at 147. Second, the court's finding that URI and the State were the same "party" is dictum, the State of Maryland having conceded the point. Id. Finally, although State of Maryland cites to prior state case law, see Opinion to the Governor, 94 R.I. 464, 181 A.2d 618, 621 (1962), neither case engages in an extended analysis of the Board's corporate powers or characteristics. See Moor, 411 U.S. at 721 n. 54, 93 S.Ct. at 1801 n. 54 (expressing disfavor for "conclusory" determinations of entity's legal character); Jacintoport Corp., 762 F.2d at 438 (refusing to follow state case law on immunity question where cited cases "did not deal with the precise question before us, nor was their inquiry based on even analogous jurisprudential concerns"). Thus, unlike the situation in Moor, where the Court was able to find "the clearest indication possible from California's Supreme Court of the status of California's counties," Moor, 411 U.S. at 720, 93 S.Ct. at 1801 (emphasis added), neither the focus nor the nature of the analysis in State of Maryland enables us to derive a clear indication as to the Rhode Island Supreme Court's views on the critical factors controlling the "real party in interest" determination in the context of federal diversity jurisdiction.
. For example, in Moor the county's responsibility for many traditional and essential governmental functions, including the provision of water services, flood control, rubbish disposal, and harbor and airport facilities, appears to have been accepted by the Court as affirmative evidence of citizenship. See Moor, 411 U.S. at 720, 93 S.Ct. at 1801. These governmental responsibilities were noted by the Court in acknowledging the county's power to levy taxes to finance its functions. Similarly, URI is empowered to fix and collect tuitions and fees and enjoys plenary control over these nonappropriated funds, as well as its educational functions. Cf. University of Tennessee v. United States Fidelity & Guar., Co., 670 F.Supp. 1379, 1384 (E.D.Tenn.1987) (legislature's control of tuition rates suggests "arm"). We discern from Moor a general rule of thumb: the State's delegation of essential governmental functions, together with the power to generate and control the nonappropriated revenues with which to perform those governmental functions, normally will be viewed as supporting, rather than undermining, the entity's independent status for citizenship purposes. Cf. Metcalf & Eddy, 991 F.2d at 941 n. 6 (noting that, if all traditional government functions triggered immunity protection, local school boards would have been deemed "arms" of state, and that agencies which derive revenue through "user fees" for performance of "governmental" functions are unlikely to be characterized as "arms" merely by virtue of the traditional nature of their mission) (citing Royal Caribbean Corp. v. Puerto Rico Ports Auth., 973 F.2d 8 (1st Cir.1992)).
. Some courts have held that corporate status ought not be regarded as probative unless the legislature expresses its intent to confer perpetual corporate status upon the entity. See, e.g., Hall, 742 F.2d at 299. The rationale of these cases appears to be that the legislature reserves the right to revoke all delegated powers to such a nonperpetual entity, at any time. Id. See also Kashani, 813 F.2d at 847; Jackson, 682 F.2d at 1350; Brennan, 451 F.2d at 1290. As we are unable to accept the premise that legislative enactments can be immunized from amendment by succeeding legislatures, let alone be perpetuated, we respectfully decline to follow these decisions. We note also that these decisions conflict with Moor, insofar as they suggest that most political subdivisions cannot be "citizens" because succeeding legislatures retain the power to alter or rescind prior delegations of the State's police power.
. It is not always clear in the Eleventh Amendment context whether the court has already determined that the entity is an "arm" of the State, and is referring to this provision (power to sue and be sued) only as evidence of an explicit waiver of the dependent entity's sovereign immunity. See, e.g., Rozek v. Topolnicki, 865 F.2d 1154, 1158 (10th Cir.1989); Long, 525 F.2d at 77; Soni, 513 F.2d at 352; see also supra notes 4 & 7 (discussing Vanlaarhoven's alternative "waiver" holding). The bare power to sue is unlikely to hold complete sway in the threshold "alter ego" determination either in diversity or immunity cases. See Kashani, 813 F.2d at 847 (power to sue and be sued not conclusive of autonomy); Jagnandan, 538 F.2d at 1174, 1176; Krieger, 765 F.Supp. at 760, 762; cf. Hall, 742 F.2d at 305 (deliberate withholding of power to sue highly probative of lack of autonomy). But the power to sue in the entity's own name, when coupled with other powers of self-determination typically held by distinct juridical entities (power to contract, power to buy, hold, and sell property), undeniably affords the entity some additional independence from the State, since the entity need not seek the State's consent to bring, defend, or settle a lawsuit. In this case, we note in particular that (1) URI brought suit exclusively in its own name, and (2) its counsel of record is not a legal officer of the State of Rhode Island. See Jacintoport Corp., 762 F.2d at 442 (noting commission's right to "employ private attorneys to represent it" as evidence that it has separate legal identity from State); Tradigrain, Inc. v. Mississippi State Port Auth., 701 F.2d 1131, 1136 (5th Cir.1983) (Thornberiy, J., dissenting) (noting as evidence of citizenship that Authority "employs its own counsel, and is not represented by the State of Mississippi in this action"); cf. Hall, 742 F.2d at 305 (university's counsel is state attorney general).
. The Governor appoints the chairperson as well, and two ex officio positions on the Board are occupied by members of the legislative branch. Cf. Harden, 760 F.2d at 1163 (noting the fact that executive branch officials serve as ex officio members of Board as evidence of "alter ego" status).
. Since the Board's legal title to URI property is held "in trust" for the State, R.I.Gen. Laws § 16-59-1(a), URI argues that the Board's fiduciary duty to the State, the equitable owner of the property, inhibits its discretion to administer the property as record owner. The language of the statute nevertheless suggests that the Board's business decisions to purchase, administer, and dispose of URI property are largely unrestricted, and absent misfeasance would be impervious to challenge by the State. See Kovats, 822 F.2d at 1309 (legal title to property, though held in trust, coupled with discretionary power to dispose, and to control both proceeds and income therefrom, suggests independence); cf. Hall, 742 F.2d at 306 (entity is "arm" if property held in State's name).
. The Board's power to contract is not specifically enumerated in the statute, but is implicit in the grant of "all the [other] powers . usually pertaining to public corporations...." R.I.Gen. Laws § 16-59-1. Contrary to URI's contention, we see no reason to infer that this general grant of corporate power is contradicted by other statutory provisions which specifically authorize the Board to guarantee particular loans in the state's name, see, e.g., R.I.Gen. Laws § 16-32-11 (Board empowered to guarantee student loans), 16-32-12, 14 (Board empowered to guarantee, "in the name of the state," loans to "societies of students" up to a total of $1.2 million; at default, loans "shall become state obligations in like manner as any state bond"); Jacintoport Corp., 762 F.2d at 439, 441 (State's mere guarantee of agency's bonds is too "ancillary" an effect to subvert agency's independence from State); see also infra note 17.
. Although the multi-factor test is nonweighted, courts generally agree on the primacy of the financial autonomy factor in the overall balance. See Ainsworth, 818 F.2d at 1038 (financial accountability—who pays or gets paid—is the most important factor in test); see also Fitchik, 873 F.2d at 664; Kashani, 813 F.2d at 846 (same); Hall, 742 F.2d at 304; Rutledge, 660 F.2d at 1349.
. Moreover, in view of the presumptive deference due Vanlaarhoven in the present context, see supra note 7, URX's "functional integration" theory was not being written on a blank slate. See, e.g., Rollins v. Board of Governors for Higher Educ., 761 F.Supp. 930, 931 (D.R.I.1990) (citing Vanlaarhoven as precedent); cf. Cowan v. University of Louisville Sch. of Medicine, 900 F.2d 936, 940 (6th Cir.1990) (proper to rely on federal court precedent finding school not autonomous); Dube v. State Univ. of New York, 900 F.2d 587, 594 (2d Cir.1990) (SUNY) (same), cert. denied, - U.S. -, 111 S.Ct. 2814, 115 L.Ed.2d 986 (1991); Thompson v. City of Los Angeles, 885 F.2d 1439, 1443 (9th Cir.1989) (University of California) (same); Schuler v. University of Minnesota, 788 F.2d 510, 516 (8th Cir.1986) (same), cert. denied, 479 U.S. 1056, 107 S.Ct. 932, 93 L.Ed.2d 983 (1987); Goss, 588 F.2d at 98-99 (same).
. The only provision remotely on point empowers the general assembly to appropriate such funds to the Board as the general assembly "deems necessary," R.I.Gen. Laws § 16-59-9 (emphasis added), as distinguished from such amount as "is necessary." Furthermore, as we have noted, the general assembly purposively delineated narrow categories of Board "debts" {e.g., student loan guarantees) which would become "state obligations," a seemingly superfluous undertaking if the State implicitly underwrites all Board financial obligations. See supra noté 14.
. On occasion, we have adverted to this kind of statistical evidence in the appellate record, as confirmation that a party could not establish diversity. See Perez v. Rodriguez Bou, 575 F.2d 21, 25 (1st Cir.1978) (in dicta, noting that the "extent and nature" of the Commonwealth's support for the University of Puerto Rico suggested lack of autonomy, but without describing precise statistics, or stating whether University had other forms of substantial nonappropriated income). On other occasions, we have remanded for further factfinding where it appeared that the autonomy equation was so evenly balanced that the proponent on the jurisdictional issue could not meet its ultimate burden of proof without resort to such statistical information, see, e.g., Ainsworth, 818 F.2d at 1038-39 (noting various factors supporting and undermining autonomy, and remanding to district court for hearing on whether entity receives "significant funding" from the Commonwealth), and that the parties had not been afforded a full and fair opportunity to present evidence in the trial court. Id. at 1038 n. 23 (as an alternative reason for remand, noting fact that proponent had not raised the "alter ego" issue until its appellate reply brief, denying opponent "the opportunity to argue . or to rebut" the proponent's contentions). Thus, in our earlier denial of the interlocutory appeal in this case, we acted on the side of caution and judicial economy in recommending that the district court allow the parties an opportunity to present this kind of evidence, on the chance that it might be needed to tip the "alter ego" balance in the final analysis.
. The court also expressed a firm preference for requiring preliminary disclosure of the factual "background" for an expert's opinion on direct examination. The court considered this procedure preferable to the alternatives, which were (1) to allow the evidence in on direct, then exclude it later if it were found wholly unreliable, or (2) to permit Chesterton to shoulder the bur den of testing the reliability of Osborne's methods on cross-examination, leaving the ultimate weight of the evidence to the jury.
. URI raises two other arguments on appeal. First, it contends that the district court abused its discretion by denying its motion to file a second amended complaint in November 1991 — eighteen months after the filing of its original complaint, and following jury impanelment — since URI asserted valid reasons for its lack of diligence. See Quaker State Oil Refining Corp. v. Garrity Oil Co., 884 F.2d 1510, 1517 (1st Cir.1989) (due diligence required for amendments). As far as we can discern, the amendment's only significant factual supplementation to the original complaint would allege that Chesterton's representatives "came aboard the Research vessel Endeavor while the Chesterton 1-2-3 System was actually being applied and said nothing as to its not being equal to the task of painting the ballast tanks." The amended complaint generally shifted the focus of URI's allegations from Chesterton's defective manufacture of a product to Chesterton's negligence in recommending an ill-suited product, or its failure to give adequate or continuing instructions on its use. Chesterton suffered no prejudice, however, as most of these new factual matters were in fact "tried by express or implied consent of the parties," Fed.R.Civ.P. 15(b). In any event, as the substance of the proposed amendments was wholly unrelated to the issue of damages, amendment would have been futile. See Arzuaga-Collazo v. Oriental Fed. Sav. Bank, 913 F.2d 5, 7 (1st Cir.1990) (amendment futile if there is no "meaningful indication" that amendment would make a "dispositive difference") (citing The Dartmouth Review v. Dartmouth College, 889 F.2d 13, 22-23 (1st Cir.1989)).
Similarly, URI contends that the district court improperly directed a verdict for Chesterton on Count III of the complaint, which alleged Chesterton's breach of a warranty of fitness for a particular purpose. URI merely argues that it presented sufficient evidence to establish that Chesterton had reason to know that URI intended to use the product on salt water ballast tanks, and that URI specifically relied on Chesterton's assurances of suitability. Once again, however, absent proof of damages, URI's argument is to no avail.
