Bonds Rating Methodology



  1.       Purpose and Technique

The credit worthiness rating and bond rating is a process in which the firms’ ability to repay the loan made available to them, their risk exposures, their ability to pay are determined or the risk that the principal, interest and similar liabilities of capital market instruments representing the indebtedness are not met is assessed and classified impartially and justly.

Rating is an important instrument guiding the market players. The investors direct their investments by risk categories established by rating firms. Since the classification of rating results is expressed in result symbols with international recognition in general, there exists uniformity in practice across the countries. The Kobirate rating result symbols are developed according to this principle.

The credit Worthiness Rating and Bond Rating Methodologies of Kobirate International Credit Rating and Corporate Governance Services Inc. consist of qualitative and quantitative factors.

Grades assigned by Kobirate not only reflect the company’s present financial strength but also foresee the future direction of such ability.

The bond rating is an assessment measuring firm’s ability to discharge its liabilities and to repay its debts in time and in full.

By rating, it is designed to determine how a borrower (for example issuer of bond) or a borrowing instrument (for example a debenture) is credible in general.

Firm’s ability to repay the principle and interest underwritten under a certain agreement depends on continuity of firm’s production of goods or services in stability and maintenance of a stable financial structure generating the necessary cash flows.

Accordingly, one of the most important elements in rating of bond issued is that the volume of cash inflows and cash movements are regular, and to what extent they are corresponding to the payments of principal and interest due and payable.

  1.       Rating the Issues and the Issuers

In order to initiate the bond rating service, the Bond Rating Service Agreement must be signed.

The concept of Issuer means the joint stock companies, state owned enterprises including those under privatisation under the regulations, local governments and establishments operating under special regulations relating to such administrations.

The term issue means the issue and sale of bonds by the issuers with or without public offer.

On international context, the bond rating system must contain two obviously diversified separate operational dimensions.

Firstly, corporate credit rating in which the risk that the firm that issues bond may be in default is determined. Secondly, special risk factors that might result in loss to be incurred by investors due to issuing conditions of securities issued are found out and assessed.

Kobirate’s methodology is designed systematically to consider all the basic risk factors of such two dimensions.

Borrower’s risk is measured by using the corporate credit rating methodology. In case of a bond without any feature other than maturity and interest, normally, it must bear the issuer’s rating grade.
