Understanding clean-up call options

These days, plenty of corporate bonds already come with a call option, which gives the issuer the right, but not the obligation, to buy back its bonds at a fixed price on a specified date before maturity.

But did you know that there is a type of call option that allows an issuer to buy back all of its bonds at any time, subject to a certain condition?

Just when you thought bond redemptions could not get any more unpredictable, here comes the clean-up call. 

Cleaning up the leftovers

Picture yourself dining at a fancy restaurant. The main course is steak and mashed potatoes. Thirty minutes into the meal, you’re only halfway through. The waiter asks how you’re doing and you reassure him that you can keep eating.

Fifteen minutes pass, and there’s less than a quarter of the food left. Before you know it, the waiter busses your plate without even asking, to make way for dessert.

That’s exactly how a clean-up call works in bond investing. When the amount of outstanding bonds in the market falls below a specified threshold or percentage, the issuer may choose to “clean it all up” and retire the remaining bonds.

Next, you may be wondering – how can outstanding bonds decrease just like that? 

Any volunteers?

Sometimes, in the middle of a bond’s life, its issuer will ask existing bondholders whether they are willing to sell their bonds back. This is known as a tender offer.

A tender offer is made for a variety of reasons. Maybe the issuer is awash in cash and wants to retire some of the bonds to save on interest expense. Another reason could be to strengthen its balance sheet and improve credit metrics to attract new investors.

A key characteristic of a tender offer is that investors can choose whether to sell. The issuer cannot force them to participate. To sweeten the deal, the issuer might offer to pay a price higher than the prevailing market price.

When investors participate in the tender offer and sell their bonds to the issuer, the number of outstanding bonds decreases. With enough successful tender offers, the issuer may reach a point where it can exercise its clean-up call option.

 A real bond with a clean-up call

Let’s consider an example. PLNIJ 4.75 31 is a popular quasi-sovereign bond issued by Perusahaan Listrik Negara (PLN), Indonesia’s state-owned electricity company. The bond was issued on February 2, 2026, and drew in USD 500 million. It pays a coupon interest rate of 4.75% per annum until its maturity date on February 3, 2031.

For its bond redemption features, PLNIJ 4.75 31 has a call option at a price of 100.00, exercisable one month before maturity on January 3, 2031. More importantly, there is a clean-up call, also at a price of 100.00, should the outstanding amount fall below 10% of the original issuance.

This means that if the outstanding amount of PLNIJ 4.75 31 bonds in the market falls below USD 50 million, PLN can choose to buy back all of them at the clean-up call price of 100.00.

As of this writing, PLN has not announced any tender offers for this bond, so the outstanding amount remains at USD 500 million. After all, the bond was just issued, and market yields have risen since then, giving PLN no incentive to refinance. But if tender offers become more frequent, expect investors to bid more defensively for this bond.

The clean-up call also exposes investors to reinvestment risk. Imagine holding PLNIJ 4.75 31 and choosing not to participate in any tender offer because you still enjoy the regular coupons.

Suddenly, PLN exercises the clean-up call option on its bond. As an investor, your only options are to sell in the secondary market or to PLN, whichever offers the better price.

You will no longer receive the remaining unpaid coupon payments. Although you will get your bond proceeds back, your investment options might be limited. There’s a chance that other bonds in the market won’t be able to offer a yield equal to or greater than PLNIJ 4.75 31. 

Ask and you shall receive

Like other callable bonds, a bond with a clean-up call typically offers a higher yield than a plain vanilla bond. Before investing in any bond with a clean-up call, an investor should review the issuer’s history of tender offers and ask the following questions.

How much of the bond is still outstanding compared with the amount originally issued? What is the bond’s prevailing selling price, and what is the estimated yield if the clean-up call is exercised in the near future?
