restate or read parts of a contract as a back-
ground or foundation for the question whether
the corporation performed under the contract,
such testimony is permissible, because it does
not interpret the contract, but relates to the
corporation’s performance under the contract
(i.e. whether a breach occurred), which is an
ultimate issue for the jury and to which a wit-
ness can testify under rule 704(a), provided he
does not phrase his opinion in inadequately
explored legal terms.23

                        V.
    Ionics contends nonetheless that the judg-
ment based on the verdict should be affirmed
because the statute of limitations expired on
BRA’s warranty claims. The district court had
denied summary judgment for Ionics on this
issue based on a factual dispute about the date
of the delivery of the goods, and sent the issue
to the jury, which never reached the issue
because it found that Ionics did not breach any
warranty. Given the disputed factual issue, we
cannot affirm the verdict on the limitations
ground.

   We also reject Cajun’s claim that the ver-
dict should be affirmed as to it. The district
court’s holding that Cajun would be vicari-
ously liable for Ionics’s warranty breaches is
supported bythe contractual language at issue.



   23
      Given that the combined rule 404(b) and rule
407 errors are not harmless and require a remand,
we need not decide whether the errors with respect
to Grisby’s testimony are harmless. And because
we remand, we do not discuss BRA’s additional
claim that the district court erroneously excluded
evidence relating to Ionics’s failure to disclose cer-
tain information.
