- The output should be in the form "Company - Value, Quarter - Value, Year - Value".
- The output should be in the form "Company - None, Quarter - None, Year - None", if no entities are found.
- Only use entities that exist in the final sentence.
- If Company cannot be found in the sentence, return "none" for that entity.
- If Quarter cannot be found in the sentence, return "none" for that entity.
- If Year cannot be found in the sentence, return "none" for that entity.
- If there is ambiguity finding the entity, return "none" for that entity.
