CRISIL has reaffirmed 'AAA/Stable/A1+' on the debt programmes and bank facilities of ABB. The ratings continue to reflect ABB's established market position in the power and automation technology segments, strong support from its ultimate holding company, ABB (ABB Zurich; rated 'A/Stable/A-1' by Standard & Poor's) and its robust capital structure.

These rating strengths are partially offset by the susceptibility of the company's operating margin to intense competition and its exposure to structural issues in execution of power projects.

CRISIL believes that ABB will maintain its strong market position over the medium term, supported by its technological superiority. The company will also maintain its robust financial risk profile given it strong capital structure, prudent funding of capex plans, and support from its ultimate parent ABB Zurich.

The outlook may be revised to 'Negative' if ABB's order inflow is adversely affected, if it faces sustained erosion in its operating margin, or if there is a diminution in support from ABB Zurich.

Shares of the company gained Rs 5.10, or 0.44%, to settle at Rs 1,152.95. The total volume of shares traded was 9,851 at the BSE (Wednesday).
