# Updating ownerships
Override Tactyc's calculated ownership
## **Ownership Update**
By default, Tactyc calculates the ownership at the end of each round automatically. However your actual ownership may be slightly different if there are competing SAFEs, warrants, ESOP pool or other complications involved.
To update an investment's ownership% after a specific round
1. Open the investment
2. Under **Performance Cases,** click on **+ Add** for the round you want to update and select **Ownership Update**
3. An Ownership Update event will be created. Click on **Edit** for the Ownership Update event
4. Enter the latest ownership for the company and click on **Close**

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.tactyc.io/portfolio-management/managing-rounds/updating-ownerships.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
