Before RIGGS, P.J., and LANDAU and LEESON, JJ.
LEESON, Judge.
State Farm Fire and Casualty Company (State Farm) brought this declaratory judgment action to establish that it had no obligation to defend or to indemnify its insured, Sallak, in a personal injury action commenced by appellant, Sherburn. The trial court granted State Farm's motion for summary judgment and entered a declaratory judgment. Because there is no dispute about the facts, we review to determine whether summary judgment is appropriate as a matter of law, ORCP 47 C, and affirm.
*699 On July 8, 1990, Marion County Sheriff's Officer Sherburn went to the scene of a domestic disturbance at the home of Sallak and his wife. Sherburn was injured in an altercation with Sallak while Sherburn was attempting to arrest Sallak. On July 31, 1990, Sallak pleaded guilty to resisting arrest and assaulting a public safety officer. ORS 162.315; ORS 163.208.
Sherburn subsequently filed an action in negligence against Sallak, seeking to recover damages for the injuries he suffered while arresting Sallak on July 8. Sallak tendered defense of that lawsuit to State Farm, which had issued his homeowner's policy. State Farm then brought this proceeding, seeking a declaration that it has no duty to defend or to indemnify Sallak, because of a policy exclusion for bodily injury or property damage "which is either expected or intended by an insured[.]" The trial court granted State Farm's motion in limine to prohibit Sherburn or Sallak from arguing or offering evidence that Sherburn's injuries were caused by other than the criminal assault committed by Sallak. On its own motion, the court then granted summary judgment for State Farm, on the ground that Sallak's criminal conviction "precludes any decision other than the act was intentional and that the results were intended or anticipated."
Sherburn assigns error to the granting of summary judgment. He contends that a judgment based on a guilty plea is not the equivalent of an adjudication on the merits of the case. State Farm responds that, as a matter of law, issue preclusion should apply to guilty pleas.
An insured may be precluded from contending that insurance coverage is available if, in an earlier proceeding, the facts establishing that coverage is not available have necessarily and conclusively been determined. State Farm Fire & Cas. v. Reuter, 299 Or. 155, 160, 700 P.2d 236 (1985); Casey v. N.W. Security Ins. Co., 260 Or. 485, 492, 491 P.2d 208 (1971).
It is already established in Oregon that a criminal conviction following a full adjudication can have preclusive effect in a later civil proceeding. Casey, 260 Or. at 492, 491 P.2d 208. The question in this case is whether a criminal conviction following a guilty plea can also have preclusive effect in a subsequent civil proceeding.
Issue preclusion prevents relitigation in a later proceeding of an issue of ultimate fact that has been finally determined by a valid prior proceeding. Nelson v. Emerald People's Utility Dist., 318 Or. 99, 103, 862 P.2d 1293 (1993). Issue preclusion can be based on constitutional principles, the common law or a statute. Id.; ORS 43.130.[1]
In Nelson, the Supreme Court held that:
"If one tribunal has decided an issue, the decision on that issue may preclude relitigation of the issue in another proceeding if five requirements are met:
"1. The issue in the two proceedings is identical.
"2. The issue was actually litigated and was essential to a final decision on the merits in the prior proceeding.
"3. The party sought to be precluded has had a full and fair opportunity to be heard on that issue.
"4. The party sought to be precluded was a party or was in privity with a party to the prior proceeding.
"5. The prior proceeding was the type of proceeding to which this court will give preclusive effect." 318 Or. at 104, 862 P.2d 1293. (Citations and footnote omitted.)
Here, there is no dispute that the first, third and fourth requirements of issue preclusion have been met. The issue in the criminal case and in this declaratory judgment proceeding are identical: Whether Sallak *700 knowingly or intentionally caused Sherburn's injuries.[2] Sallak had a full and fair opportunity to be heard in the criminal proceeding. He knowingly and voluntarily waived his right to a trial by jury, the right to present evidence and the right to confront witnesses, ORS 135.385, and established to a judge's satisfaction that his plea was voluntarily and intelligently made, ORS 135.390. It is true that Sherburn did not participate in the criminal proceeding. Nonetheless, he was in privity with Sallak. Reuter, 299 Or. at 167, 700 P.2d 236. Sherburn argues that the second and fifth requirements of issue preclusion have not been met, because a judgment based on a guilty plea is not the equivalent of an adjudication on the merits and because a guilty plea is not the type of proceeding to which courts will give preclusive effect.
Entry of a guilty plea does not satisfy the "actually litigated" requirement of issue preclusion, Sherburn contends, because no adversarial litigation takes place and no findings of fact are made. State Farm responds that, because Oregon "requires a multitude of procedural protections" before a guilty plea is accepted, a guilty plea should satisfy the "actually litigated" requirement for purposes of issue preclusion. Based on the undisputed facts in this case, we agree with State Farm.
A guilty plea is an admission of the ultimate facts that are the material elements of the crime charged in the indictment. State v. Hetland, 31 Or.App. 529, 534, 570 P.2d 1201, rev. den., 280 Or. 683 (1977), cert. den., 436 U.S. 909, 98 S.Ct. 2244, 56 L.Ed.2d 408 (1978). In the criminal case, Sallak pleaded guilty to "knowingly caus[ing] physical injury" to Sherburn. (Emphasis supplied.) As explained above, the trial court accepted Sherburn's guilty plea only after engaging in a colloquy with him to satisfy the court that the plea was voluntarily and intelligently made. ORS 135.390. More significantly, Oregon law also requires that
"After accepting a plea of guilty or no contest, the court shall not enter a judgment without making such inquiry as may satisfy the court that there is a factual basis for the plea." ORS 135.395. (Emphasis supplied.)
There is no dispute that the multiple safeguards surrounding the entry of a guilty plea were satisfied in this case. Because the factual basis rule requires that the trial court be convinced that the plea is founded on fact, we conclude that acceptance of Sallak's plea is the equivalent of a judicial determination of each of the material elements of Sallak's crime and satisfies the "actually litigated" requirement of issue preclusion.
The final requirement of issue preclusionwhether the prior proceeding was the type to which the courts will give preclusive effectrefers to whether an administrative forum maintains procedures that are sufficiently formal and comprehensive to be like a judicial proceeding. Fisher Broadcasting, Inc. v. Dept. of Rev., 321 Or. 341, 347 n. 6, 898 P.2d 1333 (1995); Nelson, 318 Or. at 104 n. 4, 862 P.2d 1293. A proceeding that concludes in a judicial judgment unquestionably satisfies the final requirement of issue preclusion. ORS 43.130. Cf. Tiano v. Elsensohn, 268 Or. 166, 170-71, 520 P.2d 358 (1974) (defendant's stipulation in prior proceeding was a judicial admission of a specific fact that is binding on him in a subsequent proceeding).
Our conclusion is consistent with the Ninth Circuit, which has held that, as a general rule, "the doctrine of [issue preclusion] applies equally whether the previous criminal conviction was based on a jury verdict or a guilty plea." United States v. Bejar-Matrecios, 618 F.2d 81, 83 (9th Cir.1980); see also State ex rel. Leach v. Schlaegel, 191 W.Va. 538, 447 S.E.2d 1 (1994) (guilty plea to battery estops defendant from denying that very action in subsequent civil action); Drexel Burnham Lambert Group, Inc. v. Vigilant Ins. Co., 157 Misc.2d 198, 595 N.Y.S.2d 999 (Sup.Ct.1993) (guilty plea, for purposes of collateral estoppel, is equivalent to conviction); State Mut. Ins. Co. v. Bragg, 589 A.2d *701 35, 38 (Me.1991) (argument that unilateral action in pleading guilty should not preclude victims from pursuing negligence remedy is "unpersuasive"); State Farm Fire and Cas. Co. v. Johnson, 187 Mich.App. 264, 466 N.W.2d 287, 289 (1990) (plea of guilty dispels any triable factual issue regarding defendant's intent or expectation to cause injury); Ideal Mut. Ins. Co. v. Winker, 319 N.W.2d 289, 296-97 (Iowa 1982) (guilty plea entered in criminal prosecution precludes convicted party from relitigating issue of criminality in subsequent declaratory action brought against him by insurer to construe exclusionary provision of policy). Several jurisdictions have codified the principle, see, e.g., Ariz.Rev. Stat.Ann. § 13-807 (1995) (issue preclusion extends to judgments of guilty resulting from no contest pleas), and at least one has declared that even an Alford plea[3] does not make a criminal conviction immune from application of issue preclusion. Merchants Mutual Insurance Company v. Arzillo, 98 A.D.2d 495, 472 N.Y.S.2d 97 (1984); but see Safeco Insurance Company of America v. McGrath, 42 Wash.App. 58, 708 P.2d 657 (1985) (criminal conviction based on Alford-type guilty plea not entitled to preclusive effect); Prudential Property and Casualty Insurance Company v. Kollar, 243 N.J.Super. 150, 578 A.2d 1238 (App.Div.1990) (plea of guilty to aggravated arson does not establish that defendant intended specific property damage that resulted); Aetna Casualty and Surety Company v. Niziolek, 395 Mass. 737, 481 N.E.2d 1356 (1985) (no issue preclusion because taking of guilty plea is not equivalent to an adjudication on the merits after full trial where judge must find factual basis for charge rather than plea).
The trial court did not err in granting summary judgment to State Farm.
Affirmed.
NOTES
[1]  ORS 43.130 provides, in part:

"The effect of a judgment, decree or final order in an action, suit or proceeding before a court or judge of this state or of the United States, having jurisdiction is as follows:
"* * * * *
"(2) In other cases, the judgment, decree or order is, in respect to the matter directly determined, conclusive between the parties, their representatives and their successors in interest by title subsequent to the commencement of the action, suit or proceeding, litigating the same thing, under the same title and same capacity."
[2]  The parties do not argue whether an injury that was knowingly inflicted falls within the policy exclusion for expected or intended injuries.
[3]  An Alford plea is a guilty plea in which the defendant refuses to admit commission of the criminal act or which contains a protestation of innocence. In such a situation, the trial court must determine that there is a factual basis for the plea. North Carolina v. Alford, 400 U.S. 25, 91 S.Ct. 160, 27 L.Ed.2d 162 (1970).
