Hard Call: Call Premium applies in case of early repayment in any situation. This is a typical structure for a high yield bond.
Soft Call: A typical construct for Broadly Syndicated Loans is a 101 soft call for the first 12-18 months of the life of the loan. This usually means that, in case a BSL is repriced (ie its margin is reduced) during this soft call period, a penalty/premium of 1% of the loan principal is payable to the lenders. However, there will be no penalty in case the loan is repaid during this period (ie the loan is always prepayable at Par).
