Detailed Rationale

CRISIL Ratings has reaffirmed its ‘CRISIL AAA/Stable/CRISIL A1+’ ratings on the bank loan facilities and debt instruments of Chennai Petroleum Corporation Ltd (CPCL).

 

The ratings continue to derive comfort from the strong operational, managerial, and financial support CPCL receives from its parent Indian Oil Corporation Limited (IOCL, rated ‘CRISIL AAA/Stable/CRISIL A1+’), wherein the company continues to be strategically important to its parent.

 

Operating performance has remained healthy in fiscal 2023 and during the first nine months of fiscal 2024, mainly benefited by healthy GRMs and a comfortable physical performance. Overall GRMs improved to $11.91/bbl. in fiscal 2023 as compared to $8.85/bbl. in the year previous and remained healthy at $8.98/bbl. in the first nine months of fiscal 2024. The moderation in GRMs in this fiscal is mainly led by moderation in the realised product crack spreads. Over the medium term, company’s GRMs are expected to be healthy, albeit moderated from the FY2023 levels and in-line with moderation in the product crack spread in the international markets.

 

Healthy operating performance has led the marked improvement in overall financial risk profile, with total debt reducing to Rs 3,402 crore as of September 30, 2023 from Rs 9,223 crore as on March 31, 2022. Gearing is expected to remain at less than 0.5-0.7 times as on March 31, 2024, improving from 0.68 times as on March 31, 2023 and 3.36 times seen as on March 31, 2022. Over the medium term, healthy operating performance and cash accruals should be sufficient to fund the capex needs as well as planned investments with successive moderation in debt levels keeping financial risk profile healthy.

Analytical Approach

CRISIL Ratings has centrally factored in the strong business and financial linkages with its parent, IOCL. IOCL had infused Rs 1,000 crore in fiscal 2016 through subscription of non-convertible, cumulative and redeemable preference shares to support the capital requirement of CPCL; these shares have been treated as debt. CPCL redeemed Rs 500 crore of these shares in June 2018.

Key Rating Drivers & Detailed Description

Strengths:

  • Strong operational, managerial, and financial support from the parent: CPCL is of strategic importance to IOCL as the latter has, and will continue to hold a majority stake (51.89% as on December 31, 2023) in the former. The parent has strong representation on CPCL’s board, including a common chairman. The company derives operational synergies as IOCL is also in the same business; the synergies include pooled sourcing of crude oil through IOCL, and benefits from the parent’s bulk purchase. Furthermore, IOCL buys over 90% of CPCL’s output; the company caters to the parent’s product requirement in South India. CPCL’s sales volumes are therefore not expected to be affected by the presence of any new refinery in the southern region. The company’s association with IOCL enhances financial flexibility as it is viewed at par with its parent; CPCL thus enjoys benefits related to pricing of debt facilities and favourable credit terms.

 

  • Improvement in the financial risk profile: Improved operating performance has significantly benefited the balance sheet position of the company. Adjusted gearing has improved to 0.68 times as on March 31, 2023 against 3.36 times as on March 31, 2021 while interest coverage has improved to 17.3 times in fiscal 2023 from 6.7 times in fiscal 2022. Aggregate debt had increased in fiscal 2022 to Rs 9,223 crore primarily to fund the working capital requirement, due to heightened volatility in the crude oil prices, however, strong operating performance and cash accruals has since been used to reduce borrowings to Rs. 3,402 crore as on September 30, 2023.

 

For the planned refinery expansion of 9 million metric tonne per annum (mmtpa) to be set up, CPCL has budgeted an investment of around Rs 2,570 crore, for a 25% equity stake in the joint venture, given the project cost of Rs 31,580 crore envisaged few years ago; which may increase by Rs 400-500 crore owing to inflation. For the said investment, the company has already invested Rs 868 crore as on March 31, 2023. Even on factoring in the remaining investment, the financial risk profile should remain comfortable, with adjusted gearing at below 0.5-0.7 times.

 

Weaknesses:

  • Vulnerability to volatility in crude oil prices and forex movements: Crude oil prices have been volatile over the past few years. Prices fell sharply to around $ 20 per bbl towards the end of March 2020, but subsequently recovered to pre-pandemic levels, averaging $ 64 per bbl. by the end of fiscal 2021. The geopolitical tensions once again, drove crude oil prices to above $ 100/bbl. during first quarter of fiscal 2023 which has normalized now to ~$ 75-85/bbl.  Average inventory of crude oil and finished goods of around 40 days makes CPCL's operating performance vulnerable to fluctuations in valuations of inventory stock. CPCL currently imports most of its crude oil requirement from the Middle East. Also, given sale-purchase differential in currency, margins and operating performance to remain volatile to adverse movement in foreign currency mainly USD/INR pair.

 

  • Moderate business risk profile: Being a standalone refinery, CPCL’s operating performance has a high earnings sensitivity to GRMs. CPCL’s overall GRMs was impacted in fiscal 2020 falling to (-)$1.18/bbl but recovered strongly since then and has remained healthy at $7-12/bbl. over the past years with healthy crack spreads and support from inventory gains. The improvement in operating performance in fiscal 2023 was mainly driven by the spike seen in core GRMs given the impact of the geopolitical event; which has moderated this fiscal with moderation in the realized product crack spreads. Over the medium term, company’s GRMs are expected to be healthy, albeit moderated from the FY2023 levels.

 

ESG Profile

 CRISIL Ratings believes that CPCL’s Environment, Social, and Governance (ESG) profile supports its strong credit risk profile.

 

The Oil and Gas sector has a moderate environmental and social impact, primarily driven by its raw material sourcing strategies, waste intensive process, and its direct impact on the health of the environment. CPCL has continuously focused on mitigating its environmental and social risks.

 

Key ESG highlights:

  • CPCL’s key air quality initiatives include investments it undertook to deliver BS-VI compliant fuels through its refinery, high usage of Regasified Liquefied Natural Gas (RLNG) to reduce emissions, and installing 18.85 MW of renewable energy plants, among others.
  • Its endeavour to focus on environmental factors includes many firsts in the industry in India including Asia’s first sewage reclamation plant, first public sector refinery to install windmill farm to power refinery operations and also to sell and transact through Indian Energy Exchange (IEX), first to produce rocket propellant fuel & missile fuel, convert semi-regenerative to continuous catalytic reformer etc.
  • In water management, the company was the first to adopt sea water desalination technology for refinery operations and does not consume freshwater for the production process.
  • The company has a good track record in social factors with 100% redressal of customer grievances and sexual harassment cases and ‘nil’ Lost Time Injury Frequency Rate (LTIFR). Gender diversity too has improved on-year with ~5.19% of total workforce in fiscal 2023 comprising of women employees with aggregate employee attrition of only 0.34%.
  • Its governance structure is characterized by ~23% of its board comprising independent directors, healthy investor grievance redressal and extensive disclosures.

There is growing importance of ESG among investors and lenders. CPCL’s commitment to ESG principles will play a key role in enhancing stakeholder confidence, given its high share of market borrowings in its overall debt and access to both domestic and foreign capital markets.

Liquidity: Superior

Financial flexibility remains healthy, backed by the strong funding support received from IOCL. CPCL is expected to earn strong annual cash accruals for the second consecutive year this fiscal, of Rs 2500-3000 crore; which may moderate over the medium term but still remain in Rs 1,000-1,500 crore. Debt repayments of around Rs 900 crore in fiscals 2025, comprising mainly of Rs 775 crore NCDs is expected to be repaid using internal accruals. Company has about Rs 860 crore repayments in fiscal 2026. Furthermore, on an average there has been a minimal utilisation of the fund-based limits, over the past one year.

Outlook: Stable

The ‘Stable’ outlook reflects CRISIL Rating’s outlook on CPCL’s parent. The company’s status as a subsidiary of IOCL enhances its competitive position in the domestic market. IOCL extends financial and management support to CPCL and provides assured offtake for around 90% of the latter’s finished products

Rating Sensitivity factors

Downward factors:

  • Downgrade in the credit ratings of IOCL by at least one notch or reduction in its shareholding or support philosophy towards CPCL
  • Higher-than-expected and sustained deterioration in CPCL’s standalone performance

About the Company

CPCL was incorporated as Madras Refineries Ltd in 1965, a JV between the Government of India, National Iranian Oil Co (NIOC) and American Oil Co (a wholly owned subsidiary of USA-based Standard Oil Co). In March 2001, IOCL acquired the government’s equity stake for Rs 510 crore, and NIOC transferred its stake to its affiliate, Naftiran Intertrade Co Ltd (NICL), in July 2003. Currently, IOCL holds 51.89% stake in CPCL while NICL holds 15.40%; the remainder is held by financial institutions, corporate bodies, the general public and others.

 

Currently, CPCL has a refining capacity of 10.5 mmtpa at Manali. The company produces petroleum products, lubricants, and additives. CPCL also provides high-quality feedstock such as propylene, superior kerosene, butylenes, naphtha, paraffin wax, and sulphur to other industries.

 

CPCL, through a JV, is setting up a 9-mmtpa refinery at Cauvery Basin, Nagapattinam, at an estimated project cost of Rs 31,580 crores. Both CPCL and IOCL’s board have approved the expansion plans. JV is being formed, wherein IOCL and CPCL will together hold a 50% stake (i.e. 25% each in the JV), while the remaining 50% is to be held by other seed investors. CPCL’s investment in this project would be limited to its equity investment of around Rs. 2570 crore.

 

CPCL has a high nelson complexity index (NCI) of 10.03 (refineries with high NCI have the necessary flexibility to process a variety of crude oils and can record high value addition).

 

For the nine months ended December 31, 2023, CPCL reported profit after tax (PAT) of Rs 2,099 crore on revenues of Rs 48,665 crore as against PAT of Rs 2,530 crore on revenues of Rs 58,726 crore for the corresponding period of the previous fiscal.
