• ReconciliationReconciliation is the regular comparison of two sets of records that should agree, such as a firm's securities positions and the custodian's statement, cash ledgers and bank statements, or trade details with a counterparty, followed by investigation of differences (breaks). It is a key control in operations and finance.
• Security masterA security master is the central database of reference data on financial instruments: identifiers (such as the International Securities Identification Number, ISIN), issuer, currency, coupon, maturity, asset class and corporate action terms. Downstream systems for trading, settlement, accounting and reporting take their instrument data from it, so errors spread widely.
• Fund accountingFund accounting is the daily or periodic bookkeeping of an investment fund: recording trades, income, expenses and capital activity, pricing the portfolio and calculating the net asset value per unit. It also covers financial statements, fee calculations and reconciliations with the custodian and the transfer agent.
• NAV (Net asset value)Net asset value (NAV) is the value of a fund's assets minus its liabilities. NAV per share, or per unit, is the NAV of a share class divided by the number of shares in issue, and it is the price at which investors subscribe to and redeem from an open-ended fund.
