accreted value

The current value of your zero-coupon municipal bond, taking into account interest that has been accumulating and automatically reinvested in the bond.

accretion bond

Often the last tranche in a CMO, the accretion bond, or Z-tranche, receives no cash payments for an extended period of time until the previous tranches are retired. While the other tranches are outstanding, the Z-tranche receives credit for periodic interest payments that increase its face value but are not paid out. When the other tranches are retired, the Z-tranche begins to receive cash payments that include both principal and continuing interest.

accrual bond

Often the last tranche in a CMO, the accrual bond or Z-tranche receives no cash payments for an extended period of time until the previous tranches are retired. While the other tranches are outstanding, the Z-tranche receives credit for periodic interest payments that increase its face value but are not paid out. When the other tranches are retired, the Z-tranche begins to receive cash payments that include both principal and continuing interest.

accrued interest

(1) The dollar amount of interest accrued on an issue, based on the stated interest rate on that issue, from its date to the date of delivery to the original purchaser. This is usually paid by the original purchaser to the issuer as part of the purchase price of the issue; (2) Interest deemed to be earned on a security but not yet paid to the investor.

active tranche

A CMO tranche that is currently paying principal payments to investors.

ad valorem tax

[Latin: to the value added] A tax based on the value (or assessed value) of real property.

adjustable-rate mortgage (ARM)

A mortgage loan on which interest rates are adjusted at regular intervals according to predetermined criteria. An ARM’s interest rate is tied to an objective, published interest rate index.

advance refunding

A financing structure under which new bonds are issued to repay an outstanding bond issue prior to its first call date. Generally, the proceeds of the new issue are invested in government securities, which are placed in escrow. The interest and principal repayments on these securities are then used to repay the old issue, usually on the first call date.

agency bond

A bond issued by two types of entities—1) Government Sponsored Enterprises (GSEs), usually federally-chartered but privately-owned corporations; and 2) Federal Government agencies which may issue or guarantee these bonds—to finance activities related to public purposes, such as increasing home ownership or providing agricultural assistance. Agency bonds are issued in a variety of structures, coupon rates and maturities. Each GSE and Federal agency issues its own bonds, with sizes and terms appropriate to the needs and purposes of the financing.

agency transaction

A sale and purchase of bonds in which the dealer places bonds with the buyer on a commission basis rather than selling bonds that the dealer owns.

Agreement Among Underwriters (AAU)

amortization

Liquidation of a debt through installment payments.

arbitrage

In the municipal market, the difference in interest earned on funds borrowed at a lower tax-exempt rate and interest on funds that are invested at a higher-yielding taxable rate. Under the 1986 Tax Act, with very few exceptions, arbitrage earnings must be rebated back to the federal government.

ask yield

The return an investor would receive on a Treasury security if he or she paid the ask price.

assessed valuation

The value of property against which an ad valorem tax is levied, usually a percentage of “true” or “market” value.

asset-backed bonds or securities (ABS)

Asset-backed securities, called ABS, are bonds or notes backed by financial assets other than residential or commercial mortgages—an investor is purchasing an interest in pools of loans or other financial assets. Typically these assets consist of receivables other than mortgage loans, such as credit card receivables, auto loans and consumer loans. As the underlying loans are paid off by the borrowers, the investors in ABS receive payments of interest and principal over time. The ABS market is for institutional investors and is not suitable for individual investors.

auction rate bonds

Floating-rate tax-exempt bonds where the rate is periodically reset by a dutch auction.

average life

On a mortgage security, the average time to receipt of each dollar of principal, weighted by the amount of each principal prepayment, based on prepayment assumptions.

basis point

Smallest measure used in quoting yields on bonds and notes. One basis point is 0.01% of yield. For example, a bond’s yield that changed from 6.52% to 7.19% would be said to have moved 67 basis points.

basis price

The price of a security expressed in yield, or percentage of return on the investment. Price differentials in municipal bonds are usually expressed in multiples of 5/100 of 1%, or “05."

bearer security

A security that has no identification as to owner. It is presumed to be owned by the bearer or the person who holds it. Bearer securities are freely and easily negotiable since ownership can quickly be transferred from seller to buyer. Tax-exempt municipal bonds are no longer being issued in bearer form.

benchmark

blue-sky memorandum

A memorandum for use by the account specifying the way a specific issue will be treated under state securities laws, frequently of all 50 states, Puerto Rico, and the District of Columbia. This memorandum is prepared first in preliminary form, which may note that certain steps need to be taken in various jurisdictions in order to qualify the issue for sale within these jurisdictions. The memorandum is then issued in supplemental form and generally the supplemental form reports that the required actions in the various jurisdictions have been taken.

bond

(1) The written evidence of debt, bearing a stated rate or stated rates of interest, or stating a formula for determining that rate, and maturing on a date certain, on which date and upon presentation a fixed sum of money plus interest (usually represented by interest coupons attached to the bond) is payable to the holder or owner. A municipal bond issue is usually comprised of many bonds that mature over a period of years; (2) For purposes of computations tied in to “per bond,” a $1,000 increment of an issue (no matter what the actual denominations are); (3) Bonds are long-term securities with a maturity of greater than one year.

bond anticipation note (BAN)

A note issued in anticipation of later issuance of bonds, usually payable from the proceeds of the sale of the bonds or of renewal notes. BANs can also be general obligations of the issuer.

bond bank

Agencies created by a few states to buy entire issues of bonds of municipalities. The purchases are financed by the issuance of bonds by the bond bank. The purpose is to provide better market access for small, lesser-known issuers.

The Bond Buyer™

bond purchase agreement (BPA)

The contract between the issuer and the underwriter setting forth the terms of the sale, including the price of the bonds, the interest rate or rates which the bonds are to bear and the conditions to closing. It is also called the purchase contract.

bond resolution

Issuer legal document which details the mechanics of the bond issuer, security features, covenants, events of default and other key features of the issue’s legal structure. Indentures and trust agreements are functionally similar types of documents, and the use of each depends on the individual issue and issuer.

bond swap

The sale of a bond and the purchase of another bond of similar market value. Swaps may be made to establish a tax loss, upgrade credit quality, extend or shorten maturity, etc.

bond year

An element in calculating average life of an issue and in calculating net interest cost and net interest rate on an issue. A bond year is the number of 12-month intervals between the dated date of the bond and its maturity date, measured in $1,000 increments. For example, the “bond years” allocable to a $5,000 bond dated April 1, 1980, and maturing June 1, 1981, is 5.830 [1.166 (14 months divided by 12 months) x 5 (number of $1,000 increments in $5,000 bond)].

Build America Bonds (BABs)

Build America Bonds (BABs) are new taxable municipal bonds that were authorized under the American Recovery and Reinvestment Act of 2009. Unlike municipal bonds, most of which are tax exempt, BABs are taxable bonds, which means that the interest is subject to taxation. Proceeds of these bonds can be used for the most of the same purposes as proceeds of regular tax-exempt government bonds. The two types of BABs are: Direct Payment bonds on which the United States Treasury Department pays state or local government issuers a payment equal to 35 percent of the coupon interest payments on such bonds, and Tax Credit bonds on which the bond holders receive a tax credit equal to the 35 percent of interest on such bonds.

bullet bond

call

Actions taken to pay the principal amount prior to the stated maturity date, in accordance with the provisions for “call” stated in the proceedings and the securities. Another term for call provisions is redemption provisions.

callable bonds

Bonds that are subject to payment of the principal amount (and accrued interest) prior to the stated maturity date, with or without payment of a call premium. Bonds can be callable under a number of different circumstances, including at the option of the issuer, or on a mandatory or extraordinary basis.

call date

The date at which some bonds are redeemable by the issuer prior to the maturity date. In the event of a refunded security, a prerefunded date will appear in place of any call date and will be indicated by an R = prerefunded; or an E = escrowed to maturity.

call premium

A dollar amount, usually stated as a percentage of the principal amount called, paid as a “penalty” or a “premium” for the exercise of a call provision.

call price

The specified price at which a bond will be redeemed or called prior to maturity, typically either at a premium (above par value) or at par.

call protection

Bonds that are not callable for a certain number of years before their call date.

call risk

The risk that declining interest rates may accelerate the redemption of a callable security, causing an investor’s principal to be returned sooner than expected. As a consequence, investors may have to reinvest their principal at a lower rate of interest.

cap

certificates of participation (COPs)

COPs are a structure where investors buy certificates that entitle them to receive a participation, or share, in the lease payments from a particular project The lease payments are passed through the lessor to the certificate holders with the tax advantages intact. The lessor typically assigns the lease and lease payments to a trustee, which then distributes the lease payments to the certificate holders.

clean CMO

Also known as "sequential-pay CMO," the most basic type of CMO, in which all tranches receive regular interest payments, but principal payments are directed initially only to the first tranche until it is completely retired. Once the first tranche is retired, the principal payments are applied to the second tranche until it is fully retired, and so on.

collateral

Securities or property pledged by a borrower to secure payment of a loan. If the borrower fails to repay the loan, the lender may take ownership of the collateral. Collateral for CMOs consists primarily of mortgage pass-through securities or mortgage loans, but may also encompass letters of credit, insurance policies, or other credit enhancements.

collateralize

competitive underwriting or sale

A sale of municipal securities by an issuer in which underwriters or syndicates of underwriters submit sealed bids (or oral auction bids) to purchase the securities. The securities are won and purchased by the underwriter or syndicate of underwriters which submits the best bid according to guidelines in the notice of sale. This is contrasted with a negotiated underwriting.

compound accreted value

convertible bond

A corporate bond that may be converted into shares of another security under stated terms, often into the issuing company's common stock.

convexity

Cost of Funds Index (COFI)

A bank index reflecting the weighted average interest rate paid by savings institutions on their sources of funds. There are national and regional COFI indexes.

counterparty

One of two entities in a traditional interest rate swap. In the municipal market a counterparty and a party can be a state or local government, a broker-dealer or a corporation.

coupon

This is the amount of interest due and the date on which payment is to be made. Where the coupon is blank, it can indicate that the bond can be a “ zero-coupon,” a new issue, or that it is a variable-rate bond. In the case of registered coupons (see "Registered Bond"), the interest payment is mailed directly to the registered holder. Bearer coupons are presented to the issuer's designated paying agent or deposited in a commerical bank for collection. Coupons are generally payable semiannually.

coupon payment

The actual dollar amount of interest paid to an investor. The amount is calculated by multiplying the interest of the bond by its face value.

coupon rate

covered bond

Covered bonds are debt issued by banks that are fully collateralized by residential or commercial mortgage loans or by loans to public sector institutions. The dedicated group of loans backing the covered bond is called a “cover pool.” Interest on the covered bond is paid to investors from the issuer's cash flows, while the cover pool serves as secured collateral. Covered bonds typically have high credit ratings, with most, but not all having double or triple-A ratings. Covered bonds offer an additional protection to bondholders than asset-backed debt because in addition to the collateral pool as an ultimate source of repayment, the issuing bank is also liable for repayment, although in some cases the rating of the covered bonds is based more on the collateral than on the rating of the bank. If the issuing bank is downgraded, then the covered bond may also be downgraded but this depends on the specific situation. Unlike mortgage-backed securities (MBS), covered bonds remain on an issuer's balance sheet. Another difference from MBS is that the collateral—the pool of loans—for covered bonds is dynamic, so non-performing or prepaying loans are replaced with performing assets. And, if a covered bond repays investors at an amount less than the principal and interest owed, investors retain an unsecured claim on the issuer. Covered bonds are popular in Europe, making up the second largest segment of the European bond market after government bonds. Covered bonds were first associated with Germany and Denmark and then spread throughout Europe. U.S. issuance in covered bonds started in September 2006. After the subprime crisis, the U.S. Treasury began promoting covered bonds as a safe investment for institutional investors and financing option for the housing market. The U.S. covered bond market is not a market of investments suitable for individuals.

CP Index

Most CP-based floating-rate notes are reset according to the 30- and 90-day CP composites.

CPI-U

The index for measuring the inflation rate is the non-seasonally adjusted U.S. City Average All Items Consumer Price Index for All Urban Consumers (CPI-U), published monthly by the Bureau of Labor Statistics (BLS). The CPI-U was selected by the Treasury because it is the best known and most widely accepted measure of inflation.

credit enhancement

The use of the credit of a stronger entity to strengthen the credit of a weaker entity in bond or note financing. This term is used in the context of bond insurance, bank facilities and government programs.

credit rating agency

A company that analyzes the credit worthiness of a company or security, and indicates that credit quality by means of a grade, or credit rating.

credit ratings

Designations used by ratings services to give relative indications of credit quality.

credit risk

The risk for bond investors that the issuer will default on its obligation (default risk) or that the bond value will decline and/or that the bond price performance will compare unfavorably to other bonds against which the investment is compared due either to perceived increase in the risk that an issuer will default (credit spread risk) or that a company's credit rating will be lowered (downgrade risk).

credit spread

A yield difference, typically in relation to a comparable U.S. Treasury security, that reflects the issuer’s credit quality. Credit spread also refers to the difference between the value of two securities with similar interest rates and maturities when one is sold at a higher price than the other is purchased.

current face

The current remaining monthly principal on a mortgage security. Current face is computed by multiplying the original face value of the security by the current principal balance factor.

current refunding

A financing structure under which the old bonds are called or mature within 90 days of the issuance of the new refunding bonds.

current yield

When issued, each bond is assigned a unique CUSIP number consisting of nine alphanumeric characters. 

dated date (or issue date)

The date of a bond issue from which the bondholder is entitled to receive interest, even though the bonds may actually be sold or delivered at some other date.

daycount

jump Z-tranche

A Z-tranche that may start receiving principal payments before prior tranches are retired if market forces create a "triggering" event, such as a drop in Treasury yields to a defined level, or a prepayment experience that differs from assumptions by a specific margin. "Sticky" jump Z-tranches maintain their changed payment priority until they are retired. "Non sticky" jump Z-tranches maintain their priority only temporarily, for as long as the triggering event is present. Although jump Z-tranches are no longer issued, some still trade in the secondary market.

The underwriter that serves as the lead underwriter for an account. The “manager” generally negotiates the interest rate and purchase price in a negotiated transaction or serves as the generator of the consensus for the interest rate and purchase price to be bid in a competitive bidding situation. The “manager” signs the contracts on behalf of the account and generally receives either a fee or a slightly larger spread for its services in this capacity. See also “joint managers."

mandatory sinking-fund redemption

A requirement to redeem a fixed portion of term bonds, which may comprise the entire issue, in accordance with a fixed schedule.

order period

Specific length of time when orders for new issues are placed by investors.

original delivery

The delivery of a new issue by the issuer to the original purchaser, upon payment of the purchase price. Also called “initial delivery."

pollution control bond

A debt security issued by a state, certain agencies or authorities, a local government, or development corporation to finance the construction of air- or water-pollution control facilities or sewage or solid waste disposal facilities pursuant to federal law. The bonds are backed by the credit of the beneficiary of the financing rather than the credit of the issuer. New issues of these bonds are prohibited under the 1986 Tax Law.

remarketing

A formal re-underwriting of a bond for which the form or structure is being changed.

REMIC (Real Estate Mortgage Investment Conduit)

Because of changes in the 1986 Tax Reform Act, most CMOs are now issued in REMIC form to create certain tax advantages for the issuer. The terms REMIC and CMO are now used interchangeably.

repurchase agreements (repos)

Repurchase agreements (repos) are widely used as a source of financing by primary dealers, other securities firms, banking firms, and institutional investors, among others. A repo involves an agreement between a seller and a buyer, typically of U.S. government securities but increasingly involving other types of securities and financial assets as well, whereby the seller "sells" the securities to the buyer, with a simultaneous agreement to repurchase the securities at an agreed upon price at a future point in time.

revenue anticipation note (RAN)

RANs are issued in anticipation of sources of future revenue other than taxes. This may include intergovernmental aid.

revenue bond

A bond on which the debt service is payable solely from the revenue generated from the operation of the project being financed or a category of facilities, or from other non-tax sources.

revolving trust

A securitization structure frequently used for assets with high turnover rates, such as credit card, trade and dealer floor-plan receivables. It is characterized by having a revolving period and an accumulation (or controlled-amortization) period.

risk

A measure of the degree of uncertainty and/or of financial loss inherent in an investment or decision. There are many different risks, including:

  • call risk—The risk that declining interest rates may accelerate the redemption of a callable security, causing an investor’s principal to be returned sooner than expected. As a consequence, investors may have to reinvest their principal at a lower rate of interest.
  • credit risk—The risk that the obligor on the bonds will be unable to make debt service payments due to a weakening of their credit.
  • event risk—The risk that an issuer’s ability to make debt service payments will change because of unanticipated changes, such as a corporate restructuring, a regulatory change or an accident, in their environment.
  • market risk—Potential price fluctuations in a bond due to changes in the general level of interest rates.
  • underwriting risk—The risk of pricing and underwriting securities and then ultimately not being able to sell them to the investor. </ul>

    securitization

    Securitization may be broadly defined as the process of issuing new securities backed by a pool of existing assets such as loans, residential or commercial mortgages, credit card debt, or other assets. These securities, which are generally referred to as “mortgage or asset-backed securities” are issued and sold to investors (principally institutions) and the cash flows or economic values following the assets are redirected to them. Securitization includes a diverse array of assets, such as residential and commercial mortgage loans, trade receivables, credit card balances, consumer loans, lease receivables, automobile loans, insurance receivables, commercial bank loans, health care receivables, obligations of purchasers to natural gas producers, future rights to entertainment royalty payments and other consumer and business receivables.

    security

    Specific revenue sources or assets pledged by an issuer to the bondholder to secure repayment of the bond.

    selling group

    A selling group includes dealers or brokers who have been asked to join in the offering of a new issue of securities, but are neither liable for any unsold syndicate balance, nor share in the profits of the overall syndicate. They obtain securities for sale less the take-down.

    senior manager

    The underwriter who coordinates the sale of a bond or note issue and manages a syndicate or selling group. A senior manager is usually used only with regard to a negotiated financing. The senior manager will “run the books.” If other securities firms share in the management responsibilities, they may be called co-senior managers, or, to a lesser extent, co-managers.

    senior securities

    Bonds and other debt obligations, fixed-rate capital securities and preferred stock that are considered senior to common stock within an entity’s capitalization structure.

    sequential-pay CMO

    The most basic type of CMO, in which all tranches receive regular interest payments, but principal payments are directed initially only to the first tranche until it is completely retired. Once the first tranche is retired, the principal payments are applied to the second tranche until it is fully retired, and so on.

    serial bonds

    All or a portion of an issue with stated maturities in consecutive years (as opposed to mandatory sinking fund redemption amounts).

    servicing

    Collection and pooling of principal, interest and escrow payments on mortgage loans and mortgage pools, as well as certain operational procedures such as accounting, bookkeeping, insurance, tax records, loan payment follow-up, delinquency loan follow-up and loan analysis. The party providing the servicing receives a servicing fee.

    servicing fee

    The amount retained by the mortgage servicer from monthly interest payments made on a mortgage loan.

    settlement date

    The date for the delivery of securities and payment of funds.

    short

    Borrowing and then selling securities that one does not own, in anticipation of a price decline. When prices fall, the short is “covered” by buying the securities back and returning them to the lender.

    short-term debt

    Generally, debt which matures in one year or less. However, certain securities that mature in up to three years may be considered short-term debt.

    single monthly mortality (SMM)

Usually used in connection with term bonds.

    special-purpose vehicle (SPV)

    A bankruptcy-remote entity set up to insulate the issuer of ABS (the trust) from the sponsor, or originator, of the assets. Also called special-purpose corporation (SPC).

    special tax bond

    A bond secured by a special tax, such as a gasoline tax or a sales tax.

    sponsor

    An investment firm that organizes a unit investment trust and offers the units for sale.

    spread

    When buying or selling a bond through a brokerage firm, an individual investor will be charged a commission or spread, which is the difference between the market price and cost of purchase, and sometimes a service fee. Spreads differ based on several factors including liquidity.

    spread to Treasury
    The difference between between the yield on a fixed-income security and the yield on a Treasury security of comparable maturity. For example, the spread between a 10-year Treasury yielding 4.75% and a 10-year corporate yielding 5.25% is 50 basis points.

    Standard Prepayment Model of The Securities Industry and Financial Markets Association

    A model based on historical mortgage prepayment rates that is used to estimate prepayment rates on mortgage securities. The Association’s model is based on the Constant Prepayment Rate (CPR), which annualizes the Single Monthly Mortality (SMM), or the amount of outstanding principal that is prepaid in a month. Projected and historical prepayment rates are often expressed as "percentage of PSA" (Prepayment Speed Assumptions). A prepayment rate of 100% PSA implies annualized prepayment rates of 0.2% CPR in the first month, 0.4% CPR in the second month, 0.6% CPR in the third month and 0.2% increases in every month thereafter until the 30th month, when the rate reaches 6%. From the 30th month until the mortgage loan reaches maturity, 100% PSA equals 6% CPR.

    stated maturity

    The last possible date on which the last payment of the longest loan may be paid.

    STRIPS

    Separate Trading of Registered Interest and Principal of Securities. The Treasury Department’s program under which eligible securities are authorized to be separated into principal and interest components, and transferred separately. These components are maintained in book-entry accounts and transferred in TRADES (Treasury/Reserve Automated Debt Entry System).

    subordinated debt

    A type of debt that places the investor in a lien position behind or subordinated to a company’s primary creditors. Securities issued as subordinated debt will pay interest and principal but only after all interest that is due and payable has been paid on any and all senior debt.

    super PO

    A principal-only security structured as a companion bond.

    superfloater

    A floating-rate CMO tranche whose rate is based on a formulaic relationship to a representative interest rate index.

    support tranche

    A CMO tranche that absorbs a higher level of the impact of collateral prepayment variability in order to stabilize the principal payment schedule for a PAC or TAC tranche in the same offering. Also known as a "companion tranche."

    surety bond

    A bond that backs the performance of another. In the ABS market, a surety bond is an insurance policy typically provided by a rated and regulated monoline insurance company to guarantee securities holders against default.

    swap

    A transaction in which an investor sells one security and simultaneously buys another with the proceeds, usually for about the same price and frequently for tax purposes.

    syndicate

    A group of underwriters formed for the purpose of participating jointly in the initial public offering of a new issue of municipal securities. The terms under which a “syndicate” is formed and operates are typically set forth in an “agreement among underwriters.” One or more underwriters will act as manager of the “syndicate” and one of the managers will act as lead manager and “run the books.” A “syndicate” is also often referred to as an “account” or “underwriting account."

    TAC (targeted amortization class) tranche

    A TAC tranche uses a mechanism similar to that of a sinking fund to determine a fixed principal payment schedule based on an assumed prepayment rate. The effect of prepayment variability that is removed from the TAC tranche is transferred to a companion tranche.

    take-down

    The discount from the list price allowed to a member of an underwriting account on any bonds purchased from the account.

    Tax Anticipation Note (TAN)

    TANs are issued by states or local governmental units to finance current operations in anticipation of future tax receipts. TRANS are notes that are issued in anticipation of both taxes and revenues.

    taxable municipal bond

    A municipal bond whose interest is not excluded from the gross income of its owners for federal income tax purposes. Certain municipal bonds are taxable because they are issued for purposes which the federal government deems not to provide a significant benefit to the public at large.

    tax-backed bond

    A broad category of bonds that are secured by taxes levied by the obligor. The taxes are not necessarily unlimited as to rate or amount, so while all general obligation bonds are tax backed, not all tax-backed bonds are general obligations. Examples of tax-backed bonds include moral obligations and appropriation-backed bonds. This category is also known as tax-supported.

    tax base

    The total property and resources subject to taxation. (See “assessed valuation.”)

    tax-exempt bond

    A common term for municipal bonds. The interest on the bond is excluded from the gross income of its owners for federal income tax purposes under Section 103 of the Internal Revenue Code of 1954, as amended. Municipal bonds that are also exempt from state and local as well as federal income taxes are said to have double or triple tax exemption.

    tax-exempt commercial paper

    A short-term promissory note issued for periods up to 270 days, often used in lieu of fixed-rate BANs, TANs and RANs because of the greater flexibility offered in setting both maturities and determining rates. The purpose for issuing TECP or TXCP can be the same as that for BANs, TANs and RANs.

    tax-exempt/taxable yield equivalent formula

    A formula which converts the lower yield of a tax-exempt security into the higher yield of a taxable security. The tax-exempt yield is divided by 100% less the investor’s marginal tax rate, and the resulting quotient is expressed as a percentage. This allows investors to compare equivalent yields on the two securities.

    T-bill rate

    The weekly average auction rate of the three-month Treasury bill stated as the bond equivalent yield.

    technical default

    A default under the bond indenture terms, other than nonpayment of interest or principal. Examples of technical default are failure to maintain required reserves, or to maintain adequate fees and charges for service.

    term bonds

    Bonds of an issue that have a single stated maturity date. Mandatory redemption provisions require the issuer to call or purchase a certain amount of the term bonds using money set aside in a sinking fund at regular intervals before the stated maturity date.

    term funding

    A financing done to meet specific cash-flow needs for a specific period of time.

    toggle tranche

    A Z-tranche that may start receiving principal payments before prior tranches are retired if market forces create a "triggering" event, such as a drop in Treasury yields to a defined level, or a prepayment experience that differs from assumptions by a specific margin. "Sticky" jump Z-tranches maintain their changed payment priority until they are retired. "Non sticky" jump Z-tranches maintain their priority only temporarily, for as long as the triggering event is present. Although jump Z-tranches are no longer issued, some still trade in the secondary market.

    total bonded debt

    Total general obligation bond debt outstanding of a municipality, regardless of the purpose.

    total direct debt

    The sum of the total bond debt and any unfunded debt (typically, short-term notes) of a municipality.

    The concept of disseminating price, volume and other information to the public about transactions in the municipal market.

    Treasury Inflation-Indexed Securities (TIIS)

    Securities designed to protect investors and the future value of their fixed-income investments from the adverse effects of inflation. Using the Consumer Price Index as a guide, the value of the securities' principal is adjusted to reflect the effects of inflation. Also known as Treasury Inflation Protected Securities (TIPS).

    trigger

    The market interest rate at which the terms of a security might change. Triggers are common on index amortization notes and range securities.

    triple-A claims-paying rating

    true interest cost

    A method of calculating bids for new issues of municipal securities that takes into consideration the time value of money (see “net interest cost”).

    true sale

    An actual sale, as distinct from a secured borrowing, which means that assets transferred to an SPV are not expected to be consolidated with those of the sponsor in the event of the sponsor’s bankruptcy. Rating agencies usually require what is called a true-sale opinion from a law firm before the securities can receive a rating higher than that of the sponsor.

    true yield

    The rate of return to the investor taking into account the payment of capital gains at maturity on a bond bought at a discount.

    trust agreement

    Agreement between the issuer and the trustee (1) authorizing and securing the bonds; (2) containing the issuer’s covenants and obligations with respect to the project and payment of debt service; (3) specifying the events of default; and (4) outlining the trustee’s fiduciary responsibilities and bondholders' rights. Generally does not include an assignment to the trustee of collateral to secure the payment of debt service.

    The purchase of a bond or note issue from an issuer to resell it to investors.

    underwriter

    The securities dealer who purchases a bond or note issue from an issuer and resells it to investors. If a syndicate or selling group is formed, the underwriter who coordinates the financing and runs the group is called the senior or lead manager.

    The difference between the offering price to the public by the underwriter and the purchase price the underwriter pays to the issuer. The underwriter’s expenses and selling costs are usually paid from this amount.

    undivided account

    Syndicate account structure that is undivided as to sales and liability. Also called “Eastern” account.

    unit

    A fractional, undivided interest in a unit investment trust.

    unit investment trust

It contains a put option permitting the bondholder to tender the bond for purchase when a new interest rate is established. VRDOs are also referred to as VRDNs (N=Notes), VRDBs (B=Bonds) or low floaters.

    volatility

    A statistical measure of the variance of price or yield over time. Volatility is low if the price does not change very much over a short period of time, and high if there is a greater change.

    volume cap

    Dollar limitation of private-activity bonds that are allowed to be issued, by state, each year. Legislation enacted by Congress sets the volume cap.

    yield burning

    In a refunding, the practice of a dealer marking up the price of the securities to be put in an escrow, in order to "burn the yield down" to levels that do not violate federal arbitrage regulations. Yield burning has a negative connotation.

    yield curve

    The graphical relationship between yield and maturity among bonds of different maturities and the same credit quality. This line shows the term structure of interest rates.

    yield spread

    The difference in yield between two bonds or bond indexes.

    yield to call

    A yield on a security calculated by assuming that interest payments will be paid until the call date, when the security will be redeemed at the call price.

    yield to maturity

    A yield on a security calculated by assuming that interest payments will be made until the final maturity date, at which point the principal will be repaid by the issuer. Yield to maturity is essentially the discount rate at which the present value of future payments (investment income and return of principal) equals the price of the security.

    yield to worst

    This is the lowest yield generated, given the potential stated calls prior to maturity.

    zero-coupon bond

    A bond for which no periodic interest payments are made. The investor receives one payment at maturity equal to the principal invested plus interest earned compounded semiannually at the original interest rate to maturity.

    Z-tranche

    Often the last tranche in a CMO, the Z-tranche receives no cash payments for an extended period of time until the previous tranches are retired. While the other tranches are outstanding, the Z-tranche receives credit for periodic interest payments that increase its face value but are not paid out. When the other tranches are retired, the Z-tranche begins to receive cash payments that include both principal and continuing interest.
