Definition of First-pass regression

First-pass regression

A time series regression to estimate the betas of securities portfolios.

Agency pass-throughs

Mortgage pass-through securities whose principal and interest payments are
guaranteed by government agencies, such as the Government National Mortgage Association ("Ginnie Mae"), Federal Home Loan Mortgage Corporation ("Freddie Mac") and Federal National Mortgage Association ("Fannie Mae").

Conventional pass-throughs

Also called private-label pass-throughs, any mortgage pass-through security not
guaranteed by government agencies. Compare agency pass-throughs.

First notice day

The first day, varying by contracts and exchanges, on which notices of intent to deliver
actual financial instruments or physical commodities against futures are authorized.

First-call

With CMOs, the start of the cash flow cycle for the cash flow window.

First-In-First-Out (FIFO)

A method of valuing the cost of goods sold that uses the cost of the oldest item in
inventory first.

Fully modified pass-throughs

Agency pass-throughs that guarantee the timely payment of both interest and
principal. Related: modified pass-throughs
Functional currency As defined by FASB No. 52, an affiliate's functional currency is the currency of the
primary economic environment in which the affiliate generates and expends cash.

Last-In-First-Out (LIFO)

A method of valuing inventory that uses the cost of the most recent item in
inventory first.

LIFO (Last-in-first-out)

The last-in-first-out inventory valuation methodology. A method of valuing
inventory that uses the cost of the most recent item in inventory first.

Linear regression

A statistical technique for fitting a straight line to a set of data points.

Modified pass-throughs

Agency pass-throughs that guarantee (1) timely interest payments and (2) principal
payments as collected, but no later than a specified time after they are due. Related: fully modified passthroughs

Mortgage pass-through security

Also called a passthrough, a security created when one or more mortgage
holders form a collection (pool) of mortgages sells shares or participation certificates in the pool. The cash
flow from the collateral pool is "passed through" to the security holder as monthly payments of principal,
interest, and prepayments. This is the predominant type of MBS traded in the secondary market.

Multiple regression

The estimated relationship between a dependent variable and more than one explanatory variable.

Passive portfolio strategy

A strategy that involves minimal expectational input, and instead relies on
diversification to match the performance of some market index. A passive strategy assumes that the
marketplace will reflect all available information in the price paid for securities, and therefore, does not
attempt to find mispriced securities. Related: active portfolio strategy

Pass-through rate

The net interest rate passed through to investors after deducting servicing, management,
and guarantee fees from the gross mortgage coupon.

Pass-through securities

A pool of fixed-income securities backed by a package of assets (i.e. mortgages)
where the holder receives the principal and interest payments. Related: mortgage pass-through security

Pass-through coupon rate

The interest rate paid on a securitized pool of assets, which is less than the rate
paid on the underlying loans by an amount equal to the servicing and guaranteeing fees.

Passive investment strategy

See: passive management.

Passive investment management

Buying a well-diversified portfolio to represent a broad-based market
index without attempting to search out mispriced securities.

Passive portfolio

A market index portfolio.

Perfected first lien

A first lien that is duly recorded with the cognizant governmental body so that the lender
will be able to act on it should the borrower default.

Private-label pass-throughs

Related: Conventional pass-throughs.

Regression analysis

A statistical technique that can be used to estimate relationships between variables.

Regression equation

An equation that describes the average relationship between a dependent variable and a
set of explanatory variables.

Regression toward the mean

The tendency for subsequent observations of a random variable to be closer to its mean.

Second pass regression

A cross-sectional regression of portfolio returns on betas. The estimated slope is the
measurement of the reward for bearing systematic risk during the period analyzed.

Simple linear regression

A regression analysis between only two variables, one dependent and the other explanatory.

FIFO (First In, First Out)

An inventory valuation method that presumes that the first units received were the first ones
sold.

LIFO (Last In, First Out)

An inventory valuation method that presumes that the last units received were the first ones
sold.

First-in, first-out (FIFO)

A method of accounting for inventory.

Last-in, first-out (LILO)

A method of accounting for inventory.

least squares regression analysis

a statistical technique that investigates the association between dependent and independent variables; it determines the line of "best fit" for a set of observations by minimizing the sum of the squares
of the vertical deviations between actual points and the
regression line; it can be used to determine the fixed and
variable portions of a mixed cost

multiple regression

a statistical technique that uses two or
more independent variables to predict a dependent variable

regression line

any line that goes through the means (or averages) of the set of observations for an independent variable and its dependent variables; mathematically, there is a line of “best fit,” which is the least squares regression line

simple regression

a statistical technique that uses only one independent variable to predict a dependent variable

Odd first or last period

Fixed-income securities may be purchased on dates
that do not coincide with coupon or payment dates. The length of the first and
last periods may differ from the regular period between coupons, and thus the
bond owner is not entitled to the full value of the coupon for that period.
Instead, the coupon is pro-rated according to how long the bond is held during
that period.

Regression analysis

Statistical analysis techniques that quantify the
relationship between two or more variables. The intent is quantitative
prediction or forecasting, particularly using a small population to forecast the
behavior of a large population.

First in, first-out costing method (FIFO)

A process costing methodology that assigns the earliest
cost of production and materials to those units being sold, while the latest costs
of production and materials are assigned to those units still retained in inventory.

Last-in, first-out (LIFO)

An inventory costing methodology that bases the recognized cost of
sales on the most recent costs incurred, while the cost of ending inventory is based
on the earliest costs incurred. The underlying reasoning for this costing system is
the assumption that goods are sold in the reverse order of their manufacture.

First-In, First-Out (FIFO) Inventory Method

The inventory cost-flow assumption that
assigns the earliest inventory acquisition costs to cost of goods sold. The most recent inventory
acquisition costs are assumed to remain in ending inventory.

Last-In, First-Out (LIFO) Inventory Method

The inventory cost-flow assumption that assigns the most recent inventory acquisition costs to cost of goods sold. The earliest inventory
acquisition costs are assumed to remain in ending inventory.

First-in, first-out (FIFO)

An inventory valuation method under which one assumes that the
first inventory item to be stored in a bin is the first one to be used, irrespective of
actual usage.

Last-in, first-out (LIFO)

An inventory valuation method under which one assumes that the
last inventory item to be stored in a bin is the first one to be used, irrespective of
actual usage.

First To Die Coverage

This means that there are two or more life insured on the same policy but the death benefit is paid out on the first death only. If two or more persons at the same address are purchasing life insurance at the same time, it is wise to compare the cost of this kind of coverage with individual policies having a multiple policy discount.
