The plaintiff-appellant, Barrett Computer Services, Inc. (“BCS”), appeals from the district court’s grant of summary judgment to the defendant-appellee, PDA, Inc. (“PDA”). The district court found that BCS failed to demonstrate that a genuine issue of material fact existed as to whether BCS had standing to bring suit against PDA in the instant case. We now reverse the district court’s grant of summary judgment to PDA and remand for an evidentia-ry hearing on BCS’ standing to bring suit.
I. FACTS AND PROCEDURAL BACKGROUND
In April or May 1983, PDA entered into a contract with American Excel Corporation (“American Excel”) providing for the design, creation, and implementation of certain computer software programs by PDA for American Excel. At that time, American Excel was a closely held corporation, owned and operated by Gene M. Barrett (“Barrett”). In October 1983, to gain tax advantages related to PDA’s programming services, Barrett created BCS. Subsequently, Barrett informed PDA of BCS’ formation and made the following two requests: (1) that in the future PDA send all bills for its programming services to BCS and (2) that PDA resubmit all past invoices addressed to American Excel to BCS. PDA substantially complied with both requests. PDA claims, however, that its invoices continued to be paid out of an American Excel account. PDA also continued to *215 have contact with American Excel employees.
Approximately ten months later, in August 1984, Barrett sold most, or all, of his interest in American Excel to Frontier Insurance Holding Corporation (“Frontier”). The stock purchase agreement controlling this sale specified that, at the closing of the sale of American Excel, Barrett would repurchase certain items from Frontier, including the computer programs written by PDA. In his affidavit opposing PDA’s summary judgment motion, Barrett claims that at the time he purchased the programs, he also received all rights related to them — including all causes of action. Barrett’s affidavit also states that he subsequently “conveyed” the computer programs to BCS.
On February 3, 1987, BCS filed the complaint in the instant case, in the United States District Court for the Northern District of Texas, asserting diversity as the ground for federal jurisdiction. BCS’ complaint alleged the following four causes of action against PDA: (1) breach of contract, (2) Texas Deceptive Trade Practices Act violations, (3) fraud, and (4) common law negligence.
PDA denied BCS’ claims and filed a summary judgment motion in relation to BCS’ claims against it. 1 PDA based this motion on the grounds that BCS did not have standing to bring the instant suit because it lacked privity to the contract, negotiations, and services upon which its complaints were based. In the alternative, PDA claimed that even if BCS were found to have standing, PDA was entitled to a partial summary judgment because the two year statute of limitations had run on BCS’ Deceptive Trade Practices Act, fraud, and negligence claims.
The district court granted PDA’s summary judgment motion, holding that even after an opportunity for discovery, BCS did not present adequate evidence to create a genuine issue of material fact about whether it possessed the privity of contract necessary for standing. The district court found that BCS relied on an affidavit by Barrett to establish that the contractual rights, necessary for standing to bring the suit, were assigned to BCS. The district court found Barrett’s affidavit inadequate for this purpose, however, because it determined that the affidavit made a “concluso-ry” assertion that all claims related to the computer programs had been transferred to him at the time he sold American Excel. The district court held that this assertion constituted a “legal conclusion” not clearly supported by other documents presented. In addition, the district court noted the failure of BCS to produce evidence — beyond the “conclusory” statement in Barrett’s affidavit — that Barrett had, subsequent to the sale of American Excel, conveyed the computer programs to BCS. Thus, the district court found that BCS lacked the privity of contract requisite to establish standing to bring its suit against PDA. Because the district court found that BCS failed to provide sufficient proof at the summary judgment stage as to its standing to bring any of its claims, the district court did not reach PDA’s alternative grounds for partial summary judgment — the statute of limitations issue.
BCS appeals the district court’s grant of PDA’s motion for summary judgment. It alleges that a genuine issue of material fact exists as to whether BCS has standing to bring suit against PDA in relation to the PDA-American Excel contract.
II. STANDARD OF REVIEW
On appeal, we assess a district court’s decision to grant summary judgment by
*216
reviewing the record under the same standards as the district court.

III. DISCUSSION
We now turn to the specifics of the instant case. As we noted above, after considering the evidence before it, the district court found that BCS failed to provide evidence sufficient to create a genuine issue of material fact about whether BCS had standing to bring claims relating to the PDA-American Excel contract regarding the design, creation, and implementation of certain computer programs. BCS appeals the district court’s finding against it, arguing that the evidence presented against summary judgment in the affidavit of Barrett and deposition testimony of PDA demonstrate the existence of fact issues as to the following: (1) whether BCS had been assigned the rights to causes of action arising from the PDA-American Excel contract and (2) whether BCS was a donee beneficiary of the PDA-American Excel contract with the right to bring such suit. We consider these claims in turn.
A. BCS’ Claim to Standing Based on an Assignment of Rights in Relation to the PDA-American Excel Contract.
At the summary judgment proceedings, BCS claimed standing to bring the causes of action alleged in its original complaint by virtue of having been conveyed the computer programs resulting from the PDA-American Excel contract. In deciding whether or not BCS succeeded in establishing that a fact issue exists in relation to its standing to bring the claims, BCS’ evidence of assignment of claims must be considered in relation to the well-established standards for summary judgment.
Though the purpose of this inquiry is solely to determine whether a genuine fact issue exists, “the judge must view the evidence presented through the prism of the substantive evidentiary burden.”
Anderson v. Liberty Lobby, Inc.,
BCS claims that a fact issue exists as to whether such privity arose through an assignment to BCS of all rights related to the programs. To support its claim, BCS presented evidence showing that American Excel was aware of the existence of BCS and also submitted an affidavit by Barrett. In his affidavit, Barrett stated:
In August, [sic] 1984, I, as sole shareholder of American Excel Corp., sold all of the outstanding stock of American Excel Corp. to Frontier Insurance Holding Corporation. In connection with such sale I was conveyed the rights to all the programs developed by PDA, Inc. which included any causes of action related thereto or arising therefrom. I subsequently conveyed the programs to Barrett Computer Services, Inc.
From Barrett’s affidavit, it is clear that he claims to have been conveyed all the rights associated with the computer programs, as well as the programs themselves, at the sale of American Excel. In addition, although the affidavit includes a somewhat ambiguous reference, it appears that Barrett uses the term “computer programs” broadly to include not only the programs, but all the rights associated with them as well. “Reviewing] the facts drawing all inferences most favorable to the party opposing the motion[],”
Reid,
In its holding, the district court discredited Barrett’s affidavit as evidence of BCS’ right to bring suit against PDA because it found Barrett’s comments on the alleged conveyances “conclusory and his statements about the transfer of the programs from American Excel to himself to reach a “legal conclusion.” While it is true that affidavits “setting forth ‘ultimate or con-clusory facts and conclusions of law’ are insufficient to either support or defeat a motion for summary judgment,”
Galindo v. Precision Am. Corp.,
In connection with the transfer of the computer programs from American Excel to Barrett, the stock purchase agreement relatir g to the sale of American Excel confirms that Barrett bought the programs back from Frontier and shows that Barrett and Frontier reached an agreement whereby Barrett would allow American Excel to continue to use the computer programs in question. Hence, though the stock purchase agreement makes no specific reference to the assignment of any causes of action relating to the programs, it does demonstrate that Barrett received some rights in relation to the programs. In opposition, PDA offered the deposition testimony of an American Excel employee, asserting that American Excel had not assigned any possible claims to Barrett or BCS. However, as BCS is the nonmovant in this summary judgment proceeding, its evidence must be viewed drawing all reasonable factual inferences in its favor.
See Reid,
*218 In relation to the next step in establishing standing for BCS — the transfer of the causes of action from Barrett to BCS — BCS offers only Barrett’s affidavit as evidence of the assignment. As quoted, supra, his affidavit states that he conveyed the computer programs to BCS. While this is not detailed information, BCS’ offer of Barrett’s affidavit meets all of the requirements set by Fed.R.Civ.P. 56(e) for affidavits opposing summary judgment motions. That is, Barrett has personal knowledge of the alleged transaction, offers facts that would be admissible in evidence, and is competent to offer evidence on the alleged assignment of rights relating to the computer software. Moreover, because of Barrett’s instrumental positions on both sides of the alleged transaction, as both the conveyor of the computer programs and the president and owner of the corporation receiving the programs, Barrett is in a position to know whether the computer programs were actually transferred. Again, giving BCS, as nonmovant, the benefit of all reasonable factual inferences, we must assume — for the purposes of summary judgment — that the alleged conveyance of the computer programs from Barrett to BCS took place.
Based on all of the above, we find that BCS succeeded in putting forth evidence supporting its claim of privity — and, thereby, standing — in relation to the PDA-American Excel contract. As BCS is only required, at the summary judgment stage, to bring forth sufficient evidence of the essential elements on which it bears the burden of proof, we find that the district court erred in granting summary judgment to PDA and dismissing BCS’ claims on the merits. Although more concrete evidence of the conveyances of the computer programs would have been preferable, the evidence presented suffices to establish the existence of a genuine fact issue regarding BCS’ standing to bring the claims alleged in its original complaint. After all, in summary judgment proceedings, “[t]he judge’s function is not himself to weigh the evidence and determine the truth of the matter-”
Anderson,
Reaching this conclusion would normally end our consideration of the case. However, because this case came to us as an appeal from a summary judgment based on the preliminary issue of standing, we write to clarify the impact of our findings and our reasons for remanding to the district court for an evidentiary hearing. We wish to stress that our reversal of the district court does not indicate that we find BCS to have standing or a right to a trial on the merits of the claims — as is usually the case where a summary judgment motion is denied.
See, e.g., Switzerland Ass’n v. Horne’s Market,
By definition, standing goes to “the ‘case or controversy’ limitation on federal court jurisdiction, and [an inquiry into a party’s standing] focuses primarily ‘on the party seeking to get his complaint before a federal court.’ ”
Hill v. City of Houston,
Challenges to standing are disposed of in a number of ways, and it is difficult to extract a rule from the cases that clearly identifies the proper method for resolving a particular standing problem. Some are disposed of on the pleadings. See, e.g., McNair, supra. Alternatively, in cases in which the merits of the claims asserted are intertwined with the jurisdictional issue of standing, challenges to standing are frequently resolved in summary judgment proceedings — where the nonmovant is granted all reasonable factual inferences and the movant cannot succeed unless the court finds that no genuine issue of material fact exists — or at a trial on the merits. In such cases, to compel a preliminary factual inquiry into the plaintiffs standing would force the party bringing the suit tb prove merit issues in order to establish jurisdiction.
The Supreme Court’s opinions in
Gwaltney of Smithfield, v. Chesapeake Bay Foundation,
Relying on its earlier opinion in SCRAP, 4 however, the Court went on to comment on the appropriate way in which to challenge allegations going to the jurisdictional issue of standing in such cases. The Court stated:
In United States v. SCRAP, we noted that if the plaintiffs’ ‘allegations [of standing] were in fact untrue, then the [defendants] should have moved for summary judgment on the standing issue and demonstrated to the District Court that the allegations were sham and raised no genuine issue of fact.’ If the defendant fails to make such a showing after the plaintiff offers evidence to support the allegations the case proceeds to trial on the merits, where the plaintiff must prove the allegations in order to prevail. But the Constitution does not require that the plaintiff offer this proof as a *220 threshold matter in order to invoke the District Court’s jurisdiction.
Id. at 385-86. In Gwaltney and SCRAP, because it would be impossible to prove the injuries alleged for the purposes of establishing standing without also addressing the merits, a preliminary hearing of the type available in disposing of a motion to dismiss would not offer an appropriate forum for evaluating the issues. In fact, this type of intertwining of the merits and the jurisdictional issues has led some commentators to “conclude that there is little to be gained by preliminary factual inquiry into some issues of standing.” 13A Wright, Miller & Cooper, supra, § 3531.15, at 100 (citing SCRAP).
By contrast, in a case in which considerations of standing can be severed from a resolution of the merits, a preliminary hearing — to resolve disputed factual issues determining standing — is an appropriate course. Such a hearing could result from a motion to dismiss for lack of subject matter jurisdiction.
Cf. Lewis v. Knutson,
In the case at hand, the issue of BCS’ right to bring suit — whether it is a party to the PDA-American Excel contract — is sev-erable from consideration of the merits of BCS’ allegations against PDA. Because of the ease with which the two issues can be separated and because of the breadth generally allowed to courts in exploring issues that go to their own jurisdiction, we believe that the issue of BCS’ standing would be most effectively and appropriately resolved in an evidentiary hearing. Furthermore, holding such a hearing — rather than calendaring the case for trial on the basis of BCS having brought forward some disputed evidence on the preliminary issue of standing — is in the interest of conserving judicial resources. Thus, we remand to the district court for a hearing to consider BCS’ standing, in accordance with this circuit’s dictates on inquiries relating to subject matter jurisdiction.
B. BCS’ Claim to Standing as a Donee Beneficiary to the PDA-American Excel Contract.
BCS failed to raise the issue of whether it qualified as a donee beneficiary to the *221 PDA-American Excel contract in the district court. Therefore, we are constrained from addressing this issue on appeal.
IV. ORDER
For the foregoing reasons, we REVERSE the judgment of the district court granting summary judgment to the defendant-appellee PDA and dismissing the plaintiff-appellant BCS’ claims against PDA on the merits. We REMAND to the district court and instruct it to hold an evidentiary hearing on the issue of BCS’ standing.
REVERSED and REMANDED.
Notes
. PDA also filed counterclaims against BCS. In its counterclaims, PDA alleged that BCS’ pleadings in relation to PDA’s alleged violations of the Texas Deceptive Trade Practices Act were made in bad faith and that BCS made excessive demands on PDA. In relation to both of these claims, PDA requested attorneys' fees. In addition, PDA claimed that BCS tortiously interfered with the contractual relationship between PDA and its then employee Don Densmore. PDA asserted that BCS — knowing that it would violate Densmore’s employment contract with PDA — lured Densmore into "moonlighting.” As a consequence, PDA claimed that it lost revenue and, ultimately, Densmore as an employee. At the request of PDA and BCS, on January 27, 1989, the district court dismissed PDA’s counterclaims without prejudice.
. In one claim, BCS alleged breach of contract by PDA. Its other claims — Texas Deceptive Trade Practices Act violations, fraud, and negligence — are based upon alleged representations by PDA leading up to and in relation to the alleged contract.
. While Rule 56 of the Federal Rules of Civil Procedure determines the outcome of the summary judgment motion made in this case, Texas substantive law governs this suit — which is in the federal court system by virtue of diversity jurisdiction.
See Erie R.R. v. Tompkins,

SCRAP
presented a situation similar to
Gwalt-ney.
In
SCRAP,
the plaintiffs, various citizens’ groups, sought an injunction to restrain enforcement of certain orders by the Interstate Commerce Commission ("ICC") concerning a proposed 2.5% surcharge on freight rates. The plaintiffs argued that the ICC's orders were unlawful because they failed to include an environmental impact statement assessing the alleged effects of the proposed surcharge. Plaintiff SCRAP based standing on allegations that "a general rate increase would ... cause increased use of nonrecyclable commodities as compared to recyclable goods, thus resulting in the need to use more natural resources to produce such goods, some of which resources might be taken from the [plaintiffs’ area of residence], and resulting in more refuse that might be discarded in national parks in the [plaintiffs’ residence] area."

Lewis
is particularly helpful on this subject. In
Lewis,
the district court "converted” a motion to dismiss for lack of standing into a summary judgment motion on the same grounds.
Lewis,
. Fed.R.Civ.P. 12(h)(3) reads as follows: "Whenever it appears by suggestion of the parties or otherwise that the court lacks jurisdiction of the subject matter, the court shall dismiss the action.”
