The document discusses disinvestment and payback period. It defines disinvestment as a government or organization selling or liquidating an asset or subsidiary. The objectives of disinvestment include reducing financial burden, improving public finances, and introducing competition.

Payback period is used to measure risk, control the effects of uncertain future cash flows, and minimize the impact on liquidity.
