National Pension System's (NPS) scheme C, or corporate debt, takes care of the fixed income exposure for subscribers. You can either choose the active or the auto-choice mode. Under active choice, you can allocate 100 percent of your contribution towards scheme C. If you choose auto-choice, your asset allocation will be linked to your age and risk appetite. Auto mode offers three life-cycle funds based on risk profile - conservative, moderate and aggressive life-cycle funds. You can invest a maximum of up to 45 percent in scheme C under the conservative option, up to 35 years of age. Lowest exposure allowed to corporate bonds is 5 percent under the conservative option, at the age of 55.
