"The board of directors of the company (CIL)...has approved to convert the loan and Current Account Balance granted to BCCL, its 100 per cent subsidiary, aggregating to Rs 2,539 crore into 5 per cent non-convertible, redeemable cumulative preference shares," Coal India (CIL) said in a filing to the BSE.
The decision was taken at the company's board meeting held on Monday.
CIL further said in order to facilitate this, the board has approved to amend the Memorandum of Association & Articles of Association of BCCL.
"This is however subject to the approval of shareholders of BCCL," the statement added.
Dhanbad-based BCCL had earlier said that it has come out of the Board for Industrial and Financial Reconstruction (BIFR). The coal firm was loss-making and eventually referred to the BIFR.
BCCL, the only producer of prime coking coal in the country, was previously referred as a perennially sick undertaking. The company was de-listed from the lit of sick industries, after turning net worth positive.
BCCL meets almost 50 per cent of the total prime coking coal requirement of the integrated steel sector. It was incorporated to operate coking coal mines operating in the Jharia and Raniganj coalfields.
