Debt Component in Nifty

Hi,

I am trying to value a stock using CAPM. The company is debt free and profit making but the Beta w.r.t. Nifty is 1.09 (per reuters) To make sense of the market premium on Nifty and use it to calculate the cost of capital of company, I need the amount of debt that the components of nifty i.e. Nifty 50 companies hold. I mean to say, what is the leverage in Nifty? This will help me reduce the market premium required on the subject company to that extent.

Please direct me to your source.

Thanks
