 ## Minimum balance
 
-Stellar accounts must maintain a minimum balance to exist, which is calculated using the base reserve. An account must always maintain a minimum balance of two base reserves (currently 1 XLM). Every subentry after that requires an additional base reserve (currently 0.5 XLM) and increases the account’s minimum balance. Subentries include trustlines (for both traditional assets and pool shares), offers, signers, and data entries. An account cannot have more than 1,000 subentries.

Every subentry after that requires an additional base reserve (currently 0.5 XLM) and increases the account’s minimum balance. Subentries include trustlines (for both traditional assets and pool shares), offers, signers, and data entries. A pool share trustline is the one exception: it counts as two subentries, so it requires two base reserves (currently 1 XLM) instead of one. Learn more in the [Liquidity Pools section](./liquidity-on-stellar-sdex-liquidity-pools.mdx#trustlines). An account cannot have more than 1,000 subentries.
 
 Data also lives on the ledger as ledger entries. Ledger entries include claimable balances (which require a base reserve per claimant) and liquidity pool deposits and withdrawals.
 
 For example, an account with one trustline, two offers, and a claimable balance with one claimant has a minimum balance of:
 
-2 base reserves (1 XLM) + 3 subentries/base reserves (1.5 XLM) + 1 ledger entry/base reserve (1 XLM) = 3.5 XLM
+2 base reserves (1 XLM) + 3 subentries/base reserves (1.5 XLM) + 1 claimant/base reserve (0.5 XLM) = 3 XLM
 
 Minimum balance is not the same as the balance an account can spend. Selling liabilities (the amount an account has committed to open sell offers) are not part of the minimum balance. They reduce the balance available above it: `available balance` = `balance` - `minimum balance` - `liabilities.selling`.

 Account data is stored in subentries, each of which increases an account’s minimum balance by one base reserve (0.5 XLM). An account cannot have more than 1,000 subentries. Possible subentries are:
 
-- Trustlines (includes traditional assets and pool shares)
+- Trustlines for traditional assets (one subentry each)
+- Trustlines for pool shares (two subentries each)
 - Offers
 - Additional signers
 - Data entries (includes data made with the `manageData` operation, not smart contract ledger entries)
 
+A pool share trustline is the one exception to the rule above: it counts as two subentries, so it requires two base reserves (currently 1 XLM) and it counts twice toward the 1,000 subentry limit.

 ## Trustlines
 
 Trustlines are an explicit opt-in for an account to hold a particular asset. To hold a specific asset, an account must establish a trustline with the issuing account using the [`change_trust` operation](../transactions/list-of-operations.mdx#change-trust). Trustlines track the balance of an asset and can also limit the amount of an asset that an account can hold.
