 ## Retrieve related entities by expanding collection-valued navigation properties
 
-If you expand on collection-valued navigation parameters to retrieve related entities for entity sets, an `@odata.nextLink` property will be returned for the related entities. You should use the value of the `@odata.nextLink` property with a new `GET` request to return the required data.  
+If you expand on collection-valued navigation parameters to retrieve related entities for entity sets, only one level of depth is returned if there is data. Otherwise the collection will return an empty array.
 
-The following example retrieves the tasks assigned to the top 2 account records.  
+In either case an `@odata.nextLink` property will be returned for the related entities. If you want to retrieve the collection separately, you can use the value of the `@odata.nextLink` property with a new `GET` request to return the required data.

 ## Retrieve related entities by expanding both single-valued and collection-valued navigation properties
 
-The following example demonstrates how you can expand related entities for entity sets using both single- and collection-valued navigation properties. As explained earlier, expanding on collection-valued navigation properties to retrieve related entities for entity sets returns an `@odata.nextLink` property for the related entities. You should use the value of the `@odata.nextLink` property with a new `GET` request to return the required data.

 In this example, we are retrieving the contact and tasks assigned to the top 2 accounts.
