CRISIL has assigned its 'A1+' rating to the commercial paper of PTC India (PTC), while reaffirming its rating on the company's short-term bank facilities at 'A1+'.

The rating continues to reflect PTC's leadership position in the power-trading market in India, its strong relationship with customers and market linkages which emanate from its track record, audits strong financial risk profile.

These rating strengths are partially offset by PTC's exposure to counterparty risks and to risks related to open positions and threat of disintermediation.

Shares of the company gained Rs 0.25, or 0.29%, to trade at Rs 86.65. The total volume of shares traded was 122,608 at the BSE (1.33 p.m., Monday).
