Rating Rationale

Acuité has downgraded the long-term rating to 'ACUITE B‘ (read as ACUITE B) from ‘ACUITE B+’ (read as ACUITE B plus) on the Rs. 6.75 crore bank facilities of Microbiological Laboratory (ML) on account of information risk. The rating continues to be flagged as "Issuer Not-Cooperating" and is based on the best available information.

It provides a wide range of laboratory investigation services necessary for patient care in the discipline of biochemistry, clinical pathology, haematology, immunology and microbiology, among others.

Unsupported Rating

Not Applicable

Non-cooperation by the issuer/borrower:

Acuité has been requesting for data, information and undertakings from the rated entity for conducting surveillance & review of the rating. However, the issuer/borrower failed to submit such information before the due date. Acuité believes that information risk is a critical component in such ratings, and non-cooperation by the issuer along with unwillingness to provide information could be a sign of potential deterioration in its overall credit quality. This rating is, therefore, being flagged as “Issuer not-cooperating”, in line with prevailing SEBI regulations and Acuité’s policies.

Limitation regarding information availability

This rating is based on information available from sources other than the issuer / borrower (in the absence of information provided by the issuer / borrower) . Acuite endeavoured to gather information about the entity/industry from the public domain. Any rating with the suffix 'Issuer not cooperating' is assigned without any management interaction with the issuer entity or any data / information from the entity. Sometimes this non co-operation by a rated entity may be due to a result of deterioration in the credit risk profile of the entity. Therefore, Acuité cautions lenders and investors regarding the use of such information, on which the indicative credit rating is based.

Note on complexity levels of the rated instrument

In order to inform the investors about complexity of instruments, Acuité has categorized such instruments in three levels: Simple, Complex and Highly Complex. Acuite’s categorisation of the instruments across the three categories is based on factors like variability of the returns to the investors, uncertainty in cash flow patterns, number of counterparties and general understanding of the instrument by the market. It has to be understood that complexity is different from credit risk and even an instrument categorized as 'Simple' can carry high levels of risk. For more details, please refer Rating Criteria “Complexity Level Of Financial Instruments” on www.acuite.in.
