Definition of Weighted average maturity

Weighted average maturity

The WAM of a MBS is the weighted average of the remaining terms to maturity
of the mortgages underlying the collateral pool at the date of issue, using as the weighting factor the balance
of each of the mortgages as of the issue date.

Weighted average remaining maturity

The average remaining term of the mortgages underlying a MBS.

Arithmetic average (mean) rate of return

Arithmetic mean return.

Average

An arithmetic mean of selected stocks intended to represent the behavior of the market or some
component of it. One good example is the widely quoted Dow Jones Industrial average, which adds the
current prices of the 30 DJIA's stocks, and divides the results by a predetermined number, the divisor.

Average accounting return

The average project earnings after taxes and depreciation divided by the average
book value of the investment during its life.

Average age of accounts receivable

The weighted-average age of all of the firm's outstanding invoices.

Average collection period, or days' receivables

The ratio of accounts receivables to sales, or the total
amount of credit extended per dollar of daily sales (average AR/sales * 365).

Average cost of capital

A firm's required payout to the bondholders and to the stockholders expressed as a
percentage of capital contributed to the firm. average cost of capital is computed by dividing the total
required cost of capital by the total amount of contributed capital.

Average life

Also referred to as the weighted-average life (WAL). The average number of years that each
dollar of unpaid principal due on the mortgage remains outstanding. average life is computed as the weighted average time to the receipt of all future cash flows, using as the weights the dollar amounts of the principal
paydowns.

Current time to maturity on an outstanding debt instrument.
Current / noncurrent method
Under this currency translation method, all of a foreign subsidiary's current
assets and liabilities are translated into home currency at the current exchange rate while noncurrent assets
and liabilities are translated at the historical exchange rate, that is, the rate in effect at the time the asset was
acquired or the liability incurred.

Dollar-weighted rate of return

Also called the internal rate of return, the interest rate that will make the
present value of the cash flows from all the subperiods in the evaluation period plus the terminal market value
of the portfolio equal to the initial market value of the portfolio.

Dow Jones industrial average

This is the best known U.S.index of stocks. It contains 30 stocks that trade on

Market value-weighted index

An index of a group of securities computed by calculating a weighted average
of the returns on each security in the index, with the weights proportional to outstanding market value.

For a bond, the date on which the principal is required to be repaid. In an interest rate swap, the
date that the swap stops accruing interest.

Maturity phase

A phase of company development in which earnings continue to grow at the rate of the
general economy. Related: Three-phase DDM.

The spread between any two maturity sectors of the bond market.

Maturity value

Related: par value.

Moving average

Used in charts and technical analysis, the average of security or commodity prices
constructed in a period as short as a few days or as Long as several years and showing trends for the latest
interval. As each new variable is included in calculating the average, the last variable of the series is deleted.

Original maturity

maturity at issue. For example, a five year note has an original maturity of 5 years; one
year later it has a maturity of 4 years.

With CMOs, final payment at the end of the estimated cash flow window.

Remaining maturity

The length of time remaining until a bond's maturity.

Return-to-maturity expectations

A variant of pure expectations theory which suggests that the return that an
investor will realize by rolling over short-term bonds to some investment horizon will be the same as holding
a zero-coupon bond with a maturity that is the same as that investment horizon.

Simple moving average

The mean, calculated at any time over a past period of fixed length.

Stated maturity

For the CMO tranche, the date the last payment would occur at zero CPR.

Term to maturity

The time remaining on a bond's life, or the date on which the debt will cease to exist and
the borrower will have completely paid off the amount borrowed. See: maturity.

Time to maturity

The time remaining until a financial contract expires. Also called time until expiration.

Time-weighted rate of return

Related: Geometric mean return.

Weighted average cost of capital

Expected return on a portfolio of all the firm's securities. Used as a hurdle
rate for capital investment.

Weighted average coupon

The weighted average of the gross interest rate of the mortgages underlying the
pool as of the pool issue date, with the balance of each mortgage used as the weighting factor.

Weighted average life

See:average life.

Weighted average portfolio yield

The weighted average of the yield of all the bonds in a portfolio.

Yield to maturity

The percentage rate of return paid on a bond, note or other fixed income security if you
buy and hold it to its maturity date. The calculation for YTM is based on the coupon rate, length of time to
maturity and market price. It assumes that coupon interest paid over the life of the bond will be reinvested at
the same rate.

WEIGHTED AVERAGE

An inventory valuation method that calculates a weighted average cost per unit for all the goods available for sale.
Multiplying that figure by the total units in ending inventory gives you the inventory’s value.

Weighted average cost of capital

See cost of capital.

Weighted average

A method of accounting for inventory.

weighted-average cost of capital

weighted means that the proportions of
debt capital and equity capital of a business are used to calculate its
average cost of capital. This key benchmark rate depends on the interest
rate(s) on its debt and the ROE goal established by a business. This is a
return-on-capital rate and can be applied either on a before-tax basis or
an after-tax basis. A business should earn at least its weighted-average
rate on the capital invested in its assets. The weighted-average cost-ofcapital
rate is used as the discount rate to calculate the present value
(PV) of specific investments.

Average Collection Period

average number of days necessary to receive cash for the sale of
a company's products. It is calculated by dividing the value of the
accounts receivable by the average daily sales for the period.

Maturity

The date or the number of days until a security is due to be paid or
a loan is to be repaid

a composite of the cost of the various sources of funds that comprise a firm’s capital structure; the minimum rate of return that must be earned on new investments so as not to dilute shareholder value

weighted average method (of process costing)

the method of cost assignment that computes an average cost per

the current period; it combines beginning inventory units
and costs with current production and costs, respectively,
to compute the average

Maturity date

The date when the issuer returns the final face value of a bond

Yield to maturity

A measure of the average rate of return that will be earned
on a bond if held to maturity.

Average inventory

The beginning inventory for a period, plus the amount at the end of
the period, divided by two. It is most commonly used in situations in which just
using the period-end inventory yields highly variable results, due to constant and
large changes in the inventory level.

Moving average inventory method

An inventory costing methodology that calls for the re-calculation of the average cost of all parts in stock after every purchase.
Therefore, the moving average is the cost of all units subsequent to the latest purchase,
divided by their total cost.

The weighted-average term to maturity of the cash flows from the bond, where the
weights are the present value of the cash flow divided by the price.

Duration

The weighted average of the time until maturity of each of the
expected cash flows of a debt security

Macaulay duration

A widely used measure of price sensitivity to yield
changes developed by Frederick Macaulay in 1938. It is measured in years and
is a weighted average-time-to-maturity of an instrument. The Macaulay
duration of an income stream, such as a coupon bond, measures how long, on
average, the owner waits before receiving a payment. It is the weighted
average of the times payments are made, with the weights at time T equal to
the present value of the money received at time T.
