The huge election funds provided by the corporates and big business for BJP is being repaid by the NDA government many fold to the donors. The PSUs, the assets of the country are being handed over to them one after another.

The method is simple. Make the PSUs in to  loss making by any method, just like purchasing more air crafts than required (Air India) or not purchasing equipment for development and expansion (BSNL). There are many other methods. After the profitable company becomes loss making,  it can be handed over the private sharks to make profit for themselves.
