Terms Used in a Bond Public Issue (Bond IPO)

A bond public issue, commonly referred to as a Bond IPO, is a process through which eligible issuers offer bonds or non-convertible debentures (NCDs) to the public for subscription. The process involves multiple intermediaries, regulatory requirements, and instrument-specific terms that investors may encounter across offer documents and application forms. Understanding the terms associated with a bond public issue is crucial for an investor who wants to invest in bonds.

Key Terms Used in a Bond Public Issue

The following are some of the key terms used in a public issue of a bond.

Registrar

The Registrar to the Issue is a SEBI-registered entity that manages the application and allotment process for a bond public issue. Responsibilities typically include processing applications, maintaining investor records, handling allotment, and coordinating refunds where applicable. The Registrar acts as a link between the issuer and investors throughout the issue process.

Debenture Trustee

A Debenture Trustee is a SEBI-registered entity appointed to represent the interests of bondholders. The trustee monitors the issuer's compliance with the terms of the bond, including security creation and covenant adherence. In the event of a default, the Debenture Trustee may initiate action on behalf of bondholders. Appointment of a Debenture Trustee is mandatory for public issues of debt securities in India.

Lead Manager

A Lead Manager, also referred to as a Book Running Lead Manager (BRLM), is a SEBI-registered merchant banker responsible for managing the bond public issue process. Responsibilities include due diligence, preparation of offer documents, coordination with regulators and exchanges, and marketing the issue to potential investors. A single issue may have multiple lead managers depending on its size and structure.

Distributors/Broker

Distributors and brokers are intermediaries that facilitate investor participation in a bond public issue. They facilitate the distribution of the issue across investor segments. Distributors may include banks, non-banking financial companies, and registered brokers empanelled by the issuer or lead managers for the specific issue.

Rating Agencies

Credit rating agencies assess the creditworthiness of the bond issuer and assign a rating to the instrument. In India, SEBI-registered agencies such as CRISIL, ICRA, CARE, and India Ratings provide these assessments. The rating reflects the agency's opinion on the issuer's ability to meet debt obligations on time. A higher rating generally indicates lower perceived credit risk. Ratings are subject to review and may be revised during the tenure of the instrument.

Application Date

The application date refers to the period during which investors may submit subscription applications for a bond public issue. This window, also referred to as the issue period or subscription period, is specified in the offer document. Applications received outside this window are generally not considered for allotment.

Issue Details

Issue details refer to the key terms and parameters of the bond public issue as disclosed in the offer document. These typically include the issue size, face value, coupon rate, tenor, interest payment frequency, credit rating, objects of the issue, and allotment terms. Investors are generally advised to review issue details in the prospectus or information memorandum before applying.

ASBA

ASBA stands for Application Supported by Blocked Amount. It is a mechanism through which an applicant's subscription amount is blocked in their bank account at the time of application rather than transferred immediately to the issuer. The blocked amount is debited only upon allotment. In cases of partial or non-allotment, the remaining amount is automatically unblocked. ASBA is the standard application mode for public issues of securities in India.

Base Issue

The base issue refers to the minimum fundraising amount that an issuer intends to raise through a bond public issue. In many cases, issuers may retain the option to accept subscriptions beyond the base issue size up to a predefined limit, known as the oversubscription option or greenshoe option. The total amount raised may therefore exceed the base issue size, subject to the terms disclosed in the offer document.

Allotment

Allotment refers to the process of assigning bonds to applicants following the close of the subscription period. Allotment is carried out in accordance with the basis of allotment disclosed in the offer document. In cases of oversubscription, allotment may be proportionate or based on draw of lots, depending on the investor category and applicable regulations. Unallotted amounts are refunded or unblocked through the ASBA mechanism.

Tranche

A tranche is a part of a larger bond issue that is offered to investors separately. An issuer may divide a bond issue into multiple tranches, with each tranche having different features such as maturity period, interest rate, issue date, or investor category. Each tranche is treated as a separate offering for investors.

Investor Categories

Bond public issues in India typically define investor categories to allocate portions of the issue across different subscriber types. Reservations for each category are specified in the offer document.

Institutional Investors

Institutional investors are large organisations that invest money on behalf of their customers, members, or stakeholders. These may include banks, insurance companies, mutual funds, pension funds, and other regulated financial institutions. A specified portion of a bond public issue may be reserved for this category.

Non-Institutional Investors

Non-institutional investors are applicants who are not classified as institutional investors or retail individual investors. This category may include companies, trusts, partnership firms, associations, and similar entities, as specified in the offer document.

High Net-Worth Individuals (HNIs)

HNIs are individual investors applying for bond amounts above the threshold specified for the retail investor category. The minimum application amount defining the HNI category is disclosed in the offer document and may vary by issue.

Retail Investors

Retail investors are individual investors applying for bonds up to a specified monetary threshold as defined in the offer document. A portion of the issue is typically reserved for this category. The maximum application amount for retail classification is disclosed in the prospectus.

Tenor

Tenor refers to the period from the date of allotment to the date of maturity of the bond. It represents the length of time for which the investor's principal remains invested with the issuer. Bond public issues may offer multiple tenor options within the same issue, each potentially carrying a different coupon rate.

Face Value

Face value, also referred to as par value or nominal value, is the principal amount of a bond as stated in the offer document. It is the amount on which coupon payments are calculated and the amount repaid to the investor at maturity. In India, the face value of bonds in public issues is typically ₹1,000.

Coupon Rate

The coupon rate is the fixed rate of interest payable by the issuer on the face value of the bond. It is expressed as a percentage per annum and specified in the offer document. Coupon payments are made at the frequency defined in the issue terms. The coupon rate remains fixed for the tenure of the bond in fixed-rate instruments.

Yield

Yield refers to the return on a bond expressed as a percentage, accounting for the purchase price, coupon payments, and maturity value. In a bond public issue, where bonds are typically allotted at face value, the yield at the time of subscription is generally equal to the coupon rate. Yield may differ from the coupon rate if the bond is subsequently traded in the secondary market at a price above or below face value.

Interest Frequency

Interest frequency refers to how often coupon payments are made to bondholders during the investment period. Common frequencies include monthly, quarterly, semi-annual, and annual. The applicable frequency for each series or option within a bond public issue is specified in the offer document. Interest frequency may vary across different series offered within the same issue.

Product Note

A product note is a summary document prepared by the issuer or intermediary that outlines the key features of the bond being offered. It typically covers the issuer's profile, instrument features, credit rating, risk factors, and subscription details in a condensed format. However, a product note is not a substitute for the prospectus and investors are generally advised to refer to the full offer document before applying.

Information Memorandum

An Information Memorandum (IM) is a detailed document prepared by the issuer disclosing material information about the company, the instrument, and the terms of the issue. The IM along with the prospectus serves as the primary disclosure document on which investors may base their subscription decision. For public issues, the primary document is generally a prospectus / shelf prospectus / tranche prospectus, while “Information Memorandum” is more commonly associated with private placement or other disclosure formats.
