ORDER
The Memorandum disposition filed January 6, 1997, is redesignated as an authored Opinion by Judge Wright.
OPINION
Plaintiff Fireman’s Fund (“Insurer”) insured defendant Alaskan Pride Partnership’s fishing vessel, the Alaskan Pride. The vessel sank in the Bering Sea in February 1993, after inexplicably taking on water. Insurer denied coverage for the loss and sued for a declaratory judgment that the loss was not covered, and the Partnership counterclaimed for coverage and for bad faith. The jury found for the Partnership on both claims, but neither party was able to establish a cause for the sinking.
On appeal, Insurer challenges several evi-dentiary rulings and jury instructions, and it argues that the jury could not have found bad faith because the cause of the sinking was unknown. The Partnership cross-appeals the court’s denial of prejudgment interest at the contract rate. We have jurisdiction under 28 U.S.C. § 1291 and we affirm.
I. Evidentiary Rulings
We review evidentiary rulings for abuse of discretion. Masson v. New Yorker Magazine, Inc.,
A. Testimony of David Holden
At trial, the Partnership presented testimony from David Holden, a claims manager for one of the subscribing underwriters on the policy. He testified that, in his opinion, the claim was “a legitimate loss” and that he “was very upset” about the denial of coverage. Insurer argues that this testimony: constituted improper lay opinion; lacked relevance; and was unduly prejudicial.
Lay opinion is admissible only if it is (1) rationally based on the perception of the witness and (2) helpful to a clear understanding of the testimony or a fact in issue. Fed. R.Evid. 701. Insurer has failed to show that Holden’s testimony was not based on his own perception. There is no evidence that he relied on a report from “the Insurers.”
Insurer also fails to show that Holden’s opinion was not “helpful.” Lay opinion is appropriate when a witness cannot explain through factual testimony the combination of circumstances that led him to formulate that opinion. United States v. Sheet,
Holden’s testimony meets this standard. His reasons for treating the Partnership’s claim as he did may well have been based on factors too numerous and complex to develop in trial testimony. In arguing that the opinion was not helpful, Insurer relies primarily on cases dealing with expert witnesses, which apply a different standard.
2. Relevance and Prejudice
Holden’s opinion tended to make more probable the Partnership’s allegation that Insurer denied its claim too hastily. It therefore was relevant under Rule 401. Rule 403 permits a court to exclude evidence “if its probative value is substantially outweighed by the danger of unfair prejudice.” District courts enjoy “wide latitude” in applying this rule. United States v. Joetzki,
That Holden’s testimony embraced the ultimate issues of coverage and bad faith does not make it unduly prejudicial. Kostelecky v. NL Acme Tool/NL Indus., Inc.,
B. Admission of Fax, Exhibit A-53
The Partnership also introduced a fax that Holden sent to Insurer’s claims supervisor, Ed Thiemann, in which he called the denial of coverage “precipitous” and said that he doubted American courts would agree with Insurer’s reasons for the denial. Like Holden’s testimony, the fax represented information that Insurer might have considered before it decided to deny coverage and
II. Jury Instructions
We review de novo whether the instructions misstated the law, Masson v. New Yorker Magazine, Inc.,
A.Proposed Instruction No. 14
Instruction No. 14 provided that, under § 45 of the Norwegian Insurance Plan, Insurer bore the initial burden of proving that the vessel sprang a leak while afloat. If that was proven, the vessel would be presumed unseaworthy and the burden would shift to the Partnership to establish coverage. Insurer argues that these shifting burdens apply to the bad faith claim. It reasons that, once the burden of proving coverage had shifted to the Partnership, its duty to investigate the claim ended. It proposed language for Instruction No. 14 incorporating this theory, which the court rejected. Insurer’s objection goes to the legal requirements of the bad faith claim, so review is de novo.
Norwegian law governs the policy and establishes the shifting burdens described in Instruction No. 14. Insurer’s proposed language improperly attempted to apply Norwegian law to the bad faith claim by using the policy to define its duty to investigate. Washington law, however, governs bad faith. That is a tort, and its elements are defined by law, not by contract. Safeco Ins. Co. v. Butler,
Even if the policy could define the duty to investigate, the proposed instruction would be improper. The policy incorporates Washington Administrative Code § 289-30-330. See Keller v. Allstate Ins. Co.,
B. Instruction No. 25
Court’s Instruction No. 25 provided that insurers “must conduct a reasonable investigation of a claim before denying coverage, and must have a reasonable basis for denying coverage.... An insurer does not have a reasonable basis for denying coverage when its denial is based on suspicion and conjecture.” (Emphasis added). Insurer’s argument that the instruction should have defined “reasonable basis” has been waived.' Fed.R.Civ.P. 51. It did not object to Instruction No. 25 on this basis, -nor did it propose a jury instruction defining this term. In fact, its proposed instructions 18 and 20 used the term “reasonable justification” without defining it.
C. Proposed Instruction No. 27
Instruction No. 27 defined the elements of bad faith under Washington law as requiring, among other things, that “the injury to Alaskan Pride Partnership was proximately caused by the breach of plaintiffs’ duty of good faith and fair dealing.” The court elsewhere defined “proximate cause” as “that cause, which in a natural and continuous sequence, unbroken by any new, independent cause, causes the event, and without which that event would not have occurred.” Court’s Instruction No. 19.
Insurer argues that the court should have required the jury to find “that a more complete investigation would have uncovered facts which would have led the plaintiffs to
III. Bad Faith
Insurer unsuccessfully moved for judgment as a matter of law on the ground that the jury could not have found bad faith because neither party was able to prove what caused the sinking.
The finding of bad faith does not conflict with the failure to find a cause for the sinking. “We are ■ bound to find the special verdicts consistent if we can do so under a fair reading of them.” Toner v. Lederle Laboratories,
Washington law permits a jury to find denial of coverage to be in bad faith even when the cause of loss is unclear. Kallevig establishes that a jury may find bad faith even if, at the time of the denial, the question of coverage appears debatable or even doubtful. While denial of coverage based on a debatable issue does not alone constitute bad faith, Gould v. Mut. Life Ins. Co. of New York,
Insurer’s reliance on Pace v. Ins. Co. of North America,
IV. Prejudgment Interest
The Partnership argues that the court erred by denying its motions to amend the judgment to add contractual interest and for reconsideration.
The court denied prejudgment interest for two reasons: the jury award for bad faith took into account the Partnership’s loss of use of the money, so prejudgment interest would constitute double recovery; and a policy exception applied, barring interest when the insured fails to provide documents and particulars. We affirm on the first ground, and need not reach the second.
The court instructed the jury that damages for bad faith must take into account all “[f]inancial losses” and “[d]amages to a going business” that result from the denial of coverage. Instruction No. 29. These damages would include loss of use of funds the Partnership would have received if the Insurer honored the claim. This is the same loss that prejudgment interest would have remedied.
That the prejudgment interest award was mandatory under the policy does not bear upon the problem of double recovery. Farm Credit Bank v. Tucker,
The Partnership argues that we must assume that the jury expected the court to award interest separately—in other words, that the jury discounted its award to present value. See United States v. Doyle,
Y. Attorneys’ Fees
We deny the Partnership’s request for attorneys’ fees on appeal. Olympic Steamship v. Centennial Ins.,
We affirm the court’s judgment in all respects and deny the Partnership’s request for attorneys’ fees.
AFFIRMED.
Notes
. Insurer’s pretrial motion preserved its objections to Holden’s testimony. Although it assumed that Holden would be called as an expert witness, it raised substantially the same issues that are raised here. Insurer did not waive the objection when it insisted that Holden be called only if the court admitted the fax, discussed infra. We will not penalize a party for its neces-
. Insurer made a similar argument at trial, when counsel stated that Holden based his opinion on a legal memorandum. Holden denied this.
. Testimony that simply tells the juiy bow to decide is not considered "helpM" as lay opinion. As discussed infra, Holden’s testimony was helpful for other reasons.
. Insurer's general objection to the court's failure to accept its proposed jury instructions preserved this issue for appeal. A generalized objection suffices when the specific objections are framed by a proposed instruction. See Katch v. Speidel Div. of Textron, Inc.,
. Insurer does not challenge the sufficiency of the evidence. We therefore need not consider arguments relating to the sufficiency of the investigation or alleged delay by the Partnership in providing documents.
. Rhode Island requires: "1) the absence of an objectively reasonable basis to deny, and 2) the insurer's subjective knowledge or its reckless disregard of the absence of such basis."
.The court initially awarded prejudgment interest at the federal rate, but then vacated its award and denied the Partnership’s motion for interest at the contractual rate.
. We apply state law to this issue, as the parties have not cited a preemptive federal rule on contractual prejudgment interest. See Morrow Crane Co. v. Affiliated. FM Ins. Co.,
. The jury heard testimony from Daniel Leston, a CPA, who described the financial losses associated with the denial of coverage. He took into account the costs and delays associated with purchasing a new vessel, the projected earnings dining the fishing season, and the profits of investing proceeds at applicable interest rates.
