base yield spread of an MBS without an operative call produces the option-adjusted spread.

Options contract

price by a certain time in order to protect, or hedge, an existing investment.

Put-call parity relationship

The relationship between the price of a put and the price of a call on the same
underlying security with the same expiration date, which prevents arbitrage opportunities. Holding the stock

exercise price. The call value equals C=S+P-PV(k).

Quality option

Also called the swap option, the seller's choice of deliverables in Treasury Bond and Treasury
note futures contract. Related: cheapest to deliver issue

Also called the binomial option pricing model.

Uncovered call

A short call option position in which the writer does not own shares of underlying stock
represented by his option contracts. Also called a "naked" call, it is much riskier for the writer than a covered
call, where the writer owns the underlying stock. If the buyer of a call exercises the option to call, the writer
would be forced to buy the stock at market price.

Yield curve option-pricing models

Models that can incorporate different volatility assumptions along the
yield curve, such as the Black-Derman-Toy model. Also called arbitrage-free option-pricing models.

Yield to call

The percentage rate of a bond or note, if you were to buy and hold the security until the call date.
This yield is valid only if the security is called prior to maturity. Generally bonds are callable over several
years and normally are called at a slight premium. The calculation of yield to call is based on the coupon rate,
length of time to the call and the market price.

acid test ratio (also called the quick ratio)

The sum of cash, accounts receivable, and short-term marketable
investments (if any) is divided by
total current liabilities to compute this ratio. Suppose that the short-term
creditors were to pounce on a business and not agree to roll over the
debts owed to them by the business. In this rather extreme scenario, the
acid test ratio reveals whether its cash and near-cash assets are enough
to pay its short-term current liabilities. This ratio is an extreme test that
is not likely to be imposed on a business unless it is in financial straits.
This ratio is quite relevant when a business is in a liquidation situation
or bankruptcy proceedings.

net income (also called the bottom line, earnings, net earnings, and net

operating earnings)
This key figure equals sales revenue for a period
less all expenses for the period; also, any extraordinary gains and losses
for the period are included in this final profit figure. Everything is taken
into account to arrive at net income, which is popularly called the bottom
line. Net income is clearly the single most important number in business
financial reports.
