What Does Current Face Mean?
Current face refers to the currentpar valueof amortgage-backed security(MBS).It reveals the remaining monthly principal on a group of home mortgages, providing investors with a snapshot of how an MBS, the vehicle collecting on these loans,is doing compared to whenit started out.
Current face is also referred to as current face value.
Key Takeaways
- Current face is the total outstanding balance of a mortgage-backed security (MBS).
- As payments come in and the principal of the underlying mortgages in the pool ispaid down, the current face declines compared to the original face.
- MBSs with the same issue date, coupon,and original face value can have greatly different current faces because they pay down at different rates.
Understanding Current Face
Mortgage-backed securities (MBSs) are home loans that are sold by the banks that issued them to a government-sponsored enterprise (GSE) or financial company. The buyers then bundle these mortgages together into a single investable security, paying out the principal and interest that they generate to the holder, usually on a monthly basis.
When an MBS is initially structured, the par value given to the pool is called theoriginal face. Simply put, the original face is the total outstanding principal balance at issue, while the current face is the total outstanding principal value at any point thereafter. Naturally, as payments come in and the principal of the underlying mortgages in the pool ispaid down, the current face declines compared to the original face.
MBSs with the same issue date, coupon,and original face value can have greatly different current faces because they pay down at different rates based on the characteristics of the underlying loans.
For example, the pool may be made up of borrowers of high creditworthiness who can refinance easily if interest rates drop. Moreover, even if the borrowers are roughly equivalent in terms of credit rating, differencesin the prepayment speed of underlying mortgages will impact the current face.
Calculating Current Face
Current face is calculated by multiplying the currentpool factor, a measure of how much of the original loan principal remains,by the MBS's original face value. A newly issued MBS will have a pool factor of one at inception. This will change over time, moving downward as the mortgages are steadily paid off.
Special Considerations
Holders of MBSs want to see the underlying mortgages repaid, as that is where they get their principal and interest on the investment from. At the same time, for the MBS to live up to its potential, it is important that the current face doesn't fall faster than planned.
When the pool factor drops quicker than expected, it results in investors generating a lower overall return than they had previously hoped for. That's because part of the income that MBSs generate comes from interest payments on the underlying mortgages. In short, the more the homeowners still owe, the more interest they must fork out to the lender—in this case, the holder of the MBS.
If prepayment increases more than projected,the current face will drop rapidly, indicating that investors aren't getting the returns that they were initiallyexpected.
Prepayment is one of the biggest risks that MBS holders face. Borrowers tend to refinance when interest rates fall and the cost to borrow money is cheaper. This is undesirable for investors. Aside from not collecting all the income they expected to receive, it also means that capital is returned to them in a low-interest environment where yields are hard to come by.
Benefits of Current Face
By looking at the current face, an investor can check the valuation assumptions that were made when the MBS was created. This leads to questions such as whether or not the assumedprepayment ratewas accurate andwhether the valuation is higher or lower than it should be inlight of the actualprepayment riskto date.
