When used as a contextual type (section [4.19](#4.19)), a union type *U* has those members that are present in any of its constituent types, with types that are unions of the respective members in the constituent types. Specifically:

* Let *S* be the set of types in *U* that has a property *P*. If *S* is not empty, *U* has a property *P* of a union type of the types of *P* from each type in *S*.
* Let *S* be the set of types in *U* that have call signatures. If *S* is not empty and the sets of call signatures of the types in *S* are identical ignoring return types,* U* has the same set of call signatures, but with return types that are unions of the return types of the respective call signatures from each type in *S*.
* Let *S* be the set of types in *U* that have construct signatures. If *S* is not empty and the sets of construct signatures of the types in *S* are identical ignoring return types,* U* has the same set of construct signatures, but with return types that are unions of the return types of the respective construct signatures from each type in *S*.
* Let *S* be the set of types in *U* that have call signatures. If *S* is not empty and the sets of call signatures of the types in *S* are identical ignoring return types, *U* has the same set of call signatures, but with return types that are unions of the return types of the respective call signatures from each type in *S*.
* Let *S* be the set of types in *U* that have construct signatures. If *S* is not empty and the sets of construct signatures of the types in *S* are identical ignoring return types, *U* has the same set of construct signatures, but with return types that are unions of the return types of the respective construct signatures from each type in *S*.
* Let *S* be the set of types in *U* that has a string index signature. If *S* is not empty, *U* has a string index signature of a union type of the types of the string index signatures from each type in *S*.
* Let *S* be the set of types in *U* that has a numeric index signature. If *S* is not empty, *U* has a numeric index signature of a union type of the types of the numeric index signatures from each type in *S*.
