# Updating the NAV
## How to update the NAV manually
1\) Consolidate the underlying [**Portfolio Value**](/onyx-user-documentation/enzyme-vault/accounting/portfolio-value.md), with the method of your choice\
2\) Under **Update Portfolio Value**, insert the proper amount. You can also fetch this amount automatically if you have set up a [Portfolio Value Provider](/onyx-user-documentation/administration-app/vault/markdown/portfolio-value-providers.md).
{% hint style="warning" %}
As you are looking at [updating your NAV](/onyx-user-documentation/administration-app/vault/markdown/updating-the-nav.md), you should only be looking at reporting the value of your investments. As such, the Portfolio Value is not supposed to include:\
\- Any accrued fees (Onyx accrues this for you and takes it into account for the NAV Calculation)\
\- Any liquidity held in the Vault smart contract that hasn't been allocated yet - the [Liquidity Buffer](/onyx-user-documentation/enzyme-vault/accounting/liquidity-buffer.md)\
\- Any accounting positions which are to be recorded separately - see [Expenses and Income](/onyx-user-documentation/enzyme-vault/accounting/expenses-and-income.md)\
\
The App will show you the "Automatically Tracked Value" that correspond to the Liquidity Buffer and the recorded Expenses and Income.
{% endhint %}
3\) Update the exchange rate if need be
4\) Execute the on-chain transaction
## Managing Asset Exchange Rate
Exchange Rates ensure that the total value of your Vault’s underlying holdings is accurately reflected when tracked assets are denominated in different currencies.
When updating Holdings Valuation, you can apply the current exchange rate to calculate the most precise NAV and Vault Share Price.
\
Vault Valuation allows you to define an exchange rate that never expires (useful when the rate is fixed or always equivalent).\
\
If the exchange rate is subject to change, Vault Valuation also lets you set an expiry date for the rate you apply.
