Under Section 27(3), subject to limits laid down by the Central Government, the Authority may borrow TEMPORARILY by way of overdraft or otherwise for:

Section 27(3) allows short-term/temporary borrowing (overdraft or other similar temporary facility) strictly for the purpose of discharging the Authority's FUNCTIONS under the Act, and even this limited borrowing power is capped by limits the Central Government lays down from time to time - it cannot be used for speculative market investment, unsecured personal loans to staff, political financing (which would in any case be entirely outside the Authority's statutory functions and likely violate Section 11's business-principles mandate), or unrelated foreign share purchases without Government approval. This distinguishes the more restrictive, function-linked temporary overdraft power under sub-section (3) from the broader, longer-term borrowing power (bonds/debentures) under sub-section (1).
