Confirm the period and account

Check the account identifier, statement dates and currency. A calendar-month statement and a mid-month snapshot cover different periods. Keep the previous closing statement available, because its ending holdings and cash provide a starting point for the new reconciliation.

Use a copy for notes and retain the original unchanged. If the statement comes through an online account, access it through the provider's known website or application rather than following an unexpected message. The review should not require sending passwords or security codes to anyone.

Reconcile cash before judging performance

Imagine a fictional cash ledger beginning at $100. A $200 deposit arrives, a purchase uses $180, a dividend adds $6 and a fee removes $2. Ending cash should be $124: $100 plus $200 minus $180 plus $6 minus $2. This calculation checks the cash movements; it says nothing yet about the investment's market return.

If the statement shows $114, investigate the $10 difference. Look for a missing charge, another transaction, a pending item or a different date boundary. Do not immediately classify the difference as investment loss. Securities prices do not explain an unexplained subtraction from a cash ledger unless a transaction connects them.

Where multiple currencies are held, reconcile each currency separately before converting totals. An exchange-rate change can affect the reported combined value without changing the foreign-currency cash quantity. Mixing those two effects makes discrepancies harder to identify.

Reconcile holdings by quantity

Start with the previous number of units, add purchases or reinvestments and subtract sales. Account for documented corporate actions or transfers. A change in market value is not the same as a change in the number owned.

For example, ten units plus a purchase of four and a sale of three should leave eleven, absent another documented event. If eleven units are present but the value is lower, the next question concerns price or currency. If only ten units appear, the quantity difference needs a separate explanation. Keeping these checks separate narrows the enquiry.

Match trades to confirmations, including the security identifier and settlement status. A trade near the statement boundary can appear in one activity section while its cash settlement occurs in another period. Read the statement's convention before treating that timing as an error.

Identify charges and income

Compare visible charges with the fee schedule and any previous estimate. Check whether a minimum, tier or promotional condition explains a difference. Some fund expenses are reflected within fund values rather than appearing as separate account deductions, so an absence of a fee line does not establish that the investment has no costs.

For distributions, compare the amount received with the payment record and any deductions shown. Keep gross and net amounts distinct. Tax reporting depends on the jurisdiction and account, so a cash ledger should not be treated as a complete tax calculation.

Review the summary only after the parts

A higher closing balance may reflect new deposits rather than investment gains. A lower balance may include a planned withdrawal. Read any performance figure's methodology before comparing it with the raw change in value. Contributions made at different dates can require a more careful return calculation than dividing the balance difference by the opening amount.

Investor.gov's confirmation guidance recommends comparison with periodic account statements. If a discrepancy remains, contact the provider through a verified channel with the statement period, transaction reference and expected calculation. Keep a record of the response and follow-up. A precise explanation of the unmatched item is more useful than sending an unstructured list of concerns or assuming that the headline balance alone proves the account is correct.
