[C]ourts interpret contracts with the goal of ascertaining the parties’ intent.
In the case of a written contract, the court determines the parties’ intent by looking first to the plain and ordinary meaning of the contract language.
- If the contract language is clear and unambiguous, the court interprets the document as a matter of law [that is, without the need for a jury — DCT] without looking to extrinsic evidence.
- If, however, the contract language is ambiguous, the trier of fact [that is, the jury, or the judge in a non-jury trial — DCT] must examine relevant extrinsic evidence in order to ascertain the parties’ intent.
