What is meant by Portfolio accounting?
The book of record for what a portfolio owns, what it cost and what it is worth. It maintains positions, tax lots and cash, applies corporate actions and accruals, and produces the valuations everything downstream depends on.
Who uses Portfolio accounting?
Operations and finance.
What gets confused with Portfolio accounting?
Fund accounting, which produces the fund's net asset value and financial statements at the fund level. Portfolio accounting answers what a portfolio holds; fund accounting answers what an investor's share of the fund is worth. Many firms need both, sometimes from the same vendor.
What should you ask a vendor about Portfolio accounting?
Ask how a restatement is handled — a correction to a trade booked three weeks ago, after reports have gone out.
