What is Mark To Market?

How does it work?

What are the essential elements you should know!

Keep reading as I have gathered exactly the information that you need!

Let’s define what “mark to market” means and why it’s important!

Are you ready?

Let’s get started!

What Is Mark To Market

A mark to market refers to an accounting system intended to evaluate the fair market value of certain assets, liabilities, or accounts whose value change over time.


The objective of performing a mark to market adjustment on an asset or liability is to better assess the market value of the assets or liabilities.

For example, if you do a mark to market real estate, you’ll appraise the value of the real estate property based on its market value as opposed to its purchase value or other evaluations.

The process of marking to the market is an accounting operation as the company does not sell the asset or security being marked.

If an asset’s value has gone up since it was initially acquired, there will be a “paper gain”.

Similarly, if the asset value has gone down over time, the company will record “paper losses” (or mark to market losses) when doing the mark to the market.

Mark To Market Definition

According to Investopedia, they define mark to market as follows:

Mark to market (MTM) is a method of measuring the fair value of accounts that can fluctuate over time, such as assets and liabilities.

In other words, “mark to market” or “MTM” is:

  • An accounting method 
  • Used to evaluate the fair market value of an asset or liability 
  • At its current market value 

Why Perform Mark To Market Operations

There are many reasons why various parties may need to get a mark to market report or perform such operations.

Companies operating in the financial services industry granting loans to borrowers may regularly adjust their accounts to reflect the market value of their loan portfolios taking into account the borrowers who are in default of making their payment.

In essence, the financial service company will reduce the value of its loans (assets on its books) by the value of its bad debt allowance.

Similarly, companies selling goods and services may want to adjust the value of their account receivables to reflect the amount they actually would expect to get.

In other words, some companies may offer a discount to customers paying early or some of their clients fail to make payments.

For the company to properly evaluate the true value of its accounts receivable, it will perform an accounting operation to determine its “realizable” value.

In addition, in the securities markets, it’s very common for financial institutions and brokerage houses to record the current market value of a trader’s securities held in a long or short position.

The market value of the securities will provide a better estimate of the value of the trader’s portfolio than the securities book value.

There may be more reasons why companies may want to record the actual value of an account on their books and what I present here is just a few use cases.

Mark to Market Accounting

What does mark to market mean in accounting?

The mark to market accounting definition is pretty simple.

In essence, a mark to market accounting method is an accounting practice where you adjust the value of an asset or liability to properly reflect its current market value.

In accounting terms, the mark to market value is the amount that you can get in the market if you were to sell the asset today or at a specific point in time.

Let’s look at a mark to market accounting example to clarify this further.

For example, companies that are traded publicly are required to publish their financial statements on a regular basis.

As such, for an investor to properly appreciate the value of a company’s assets on its balance sheet, the company will use a mark to market method to adjust the value of its assets to reflect the market value as of the end of its accounting period.

For instance, if a company had purchased a real estate property for $1,000,000 many years ago worth $10,000,000 today, it will report its current market price at $10,000,000 on its balance sheet.

If the company were to report $1,000,000 as the purchase price value or historical value, it would not properly reflect the company’s asset value or financial position.

Historical Costs

In many cases, the mark to market or MTM is contrasted with an asset’s historical value or book value.

When a company purchases an asset or acquires one, it will record the original cost as the value of the asset.

For example, an asset purchased at $500,000 will be recorded as having a historical cost of the same amount.

However, over time, the value of the asset may go down.

For the company to assess the asset’s actual market value, it can do an MTM to record the asset’s current value (that may be $25,000 today).

Market Conditions

When the market conditions are stable, marking to market provides a good perspective of a company’s asset value and financial position.

However, if the markets are unstable or there’s a crisis of some sort, the marking to market process may not properly reflect the company’s asset “sales” value.

In other words, in unfavorable markets or in low liquidity conditions, a company may not realize the value that it considered when marking its asset to market (the actual value may be lower than the market value).

Now that we’ve looked at what mark to market means, let’s look at its definition.

Financial Accounting Standards Board Guidelines

The formal process for marking an asset to market is defined by the Financial Accounting Standards Board (FASB) where proper guidelines are published for companies to follow.

Under the FASB guidelines, the notion of fair value is defined and the manner companies are required to measure the value of their asset is by adopting the generally accepted accounting principles (or GAAP).

When a company performs mark to market operations, it must not only follow the FASB and GAAP rules but must also keep its mark to market reporting up to date.

Mark To Market Investing

In the investing world, the process of evaluating the market value of securities on a daily basis is crucial.

In essence, when an investor or trader buys and sells shares, securities, derivatives, futures, or other financial instruments, the brokerage firm will mark the current market value of the securities in the trader’s account.

This is important as the brokerage firm must keep proper tab on traders using margin accounts to trade.

By marking the securities’ current value, the brokerage firm could adequately evaluate whether or not the trader is meeting its margin account requirements.

If a margin call is necessary, the trader will receive a notice to deposit the necessary funds to cover the shortfall in his or her investment portfolio.

For example, if two traders get into a futures contract where one has a short position (bearish position) and the other has a long position (bullish position), with the daily mark to market settlement, the contracting parties will need to settle their positions for so long as their futures contract position is open.

Mark To Market Example

Let’s look at a few examples of when a company may perform a mark to market calculation.

Example 1: Mark To Market Loss

An example of when a company may use a mark to market rule to adjust the price of its assets is in the financial industry sector.

A bank or financial institution granting loans and mortgages may perform a mark to market operation to properly evaluate the value of its loans by taking into consideration its bad debt.

In other words, the financial institution will evaluate its portfolio of loans and deduct the value of its bad debt to get a more accurate perspective of the realizable value of its loans.

Example 2: Accounts Receivable 

Another example where a mark to market may be used is to adjust a company’s accounts receivables based on the value of discounts, rebates, and bad debt.

If a company has $500,000 in accounts receivables on its books, will it be able to collect the full value of its accounts receivable?

To establish the “market value” of its accounts receivable, the company accountants or finance team may perform a mark to market valuation to reduce the value of the accounts receivables by deducting what it considers as bad debt or other financial incentives given to clients to pay faster.

Example 3: Securities Value

In the trading world, there are certain types of securities that could be marked to market such as futures (mark to market futures), swaps (mark to market swap), mutual funds, or other derivatives (mark to market derivatives).

For example, when dealing with futures, the contracts traded are marked to market on a daily basis to calculate a trader’s profits or losses.

With a daily mark to market, the value of the securities traded is updated every day to reflect the market value of the securities.

When the current market value is updated on an account, depending on the trader’s trading positions, the brokerage firm can make a margin call or not.

Example 4: Real Estate Replacement Value

On a more personal level, an insurance company can use the mark to the market approach to evaluate the replacement cost of an insured home or real estate property.

For example, if you purchased your home 15 years ago at $250,000 and it is now worth $600,000, it’s important for the insurance provider to know that the replacement cost of this home may be closer to $600,000 than $250,000.

To mitigate its risk and to have a better understanding of its financial exposure, the insurance company will use the mark to market rules to determine the insured property’s current value for insurance coverage purposes.

Mark To Market Meaning Takeaways 

So there you have it folks!

What is the definition of mark to market?

What is mark to market accounting?

Mark-to-market is a term used to refer to the process of using a reasonable market value of an account, asset, or liability, at a specific point in time or during an accounting period.

The main objective of using a mark to market formula to calculate the value of an asset or debt is to record the current market value of the asset or liability.

For example, a real estate property may have a historical value of $100,000 but may be worth $1,000,000 (by marking the value to market, the books will show $1,000,000 today as opposed to $100,000).

In investing and finance, the process of adjusting the value of the securities to reflect current market value is also done quite regularly particularly with futures mark to market, mutual funds, swaps, derivatives, and other securities.

Brokerage houses allowing traders to trade securities on margin accounts will want to ensure to perform a daily adjustment of the securities traded to ensure a margin call is made as needed.

In general, it’s is generally agreed that the mark-to-market allows companies to reflect the true value of their financial positions on their books.

However, when market conditions are bad like in an economic crisis or recession or when there’s a lack of liquidity for a particular asset, marking to market may become more problematic if you’re using a market-based measurement system.

I hope I was able to explain to you the meaning of MTM (Mark to Market), why it is done, how it works, how it can be problematic, and why it’s important.
