What is Mark-to-Market Accounting?
Mark-to-market accounting is an important financial practice that involves updating the value of an asset or portfolio to reflect its current market value rather than its book value. This method provides a realistic assessment of an investment’s value and ensures that both asset or liability accounts are accurately represented on the financial statements.
Balancing Margin Accounts
One critical application of mark-to-market accounting is for margin accounts. In a margin account, investors borrow money from a broker to purchase securities. To ensure the account remains in compliance with maintenance requirements, brokers will regularly assess the value of the securities in the portfolio using mark-to-market accounting. If the account’s equity falls below a certain level (typically called the maintenance margin), the investor is required to either deposit additional funds or sell off some assets to meet the maintenance requirement.
Example: Imagine you purchase $10,000 worth of stock on margin, meaning you borrowed $5,000 from your broker and put up $5,000 of your own money. If the stock’s value decreases to $8,000, your equity in the margin account drops to $3,000 ($8,000 - $5,000) and your broker could issue a margin call, requiring you to add more funds to avoid selling off your positions.
Valuing Mutual Fund Portfolios
Mutual funds employ mark-to-market accounting to determine the daily net asset value (NAV) of the fund. The NAV is essential for maintaining transparency for shareholders and ensuring that the fund’s value reflects accurate, up-to-date market prices. By valuing securities in the portfolio at their current market prices, funds provide an accurate representation of the value of each shareholder’s investment.
Example: Consider a mutual fund with a diverse portfolio of stocks and bonds that must publish its NAV daily. When market conditions are volatile, the fund’s management uses mark-to-market accounting to update the prices of its assets. If a particular stock’s market price falls, the NAV of the mutual fund will simultaneously decrease, reflecting the change in market value.
