Cut-back (Anchor)

An anchor investor bids for ₹500 crore worth of an IPO but is allotted only ₹200 crore. What happened to the rest? Welcome to the cut-back, a routine but little-understood mechanic of how hot Indian IPOs are carved up.

Setting the stage: the anchor book

Before an IPO opens to the public, the company can allot shares to anchor investors, large institutions like mutual funds, FPIs and insurers, a day in advance. Their participation, at a fixed price, signals confidence and stabilises the issue. The anchor portion is itself carved out of the QIB slice of the offer, and SEBI caps how much can be reserved for anchors.

Because there is a hard limit on the anchor portion, demand and supply must be reconciled, and that is where the cut-back appears.

How a cut-back works

When the combined demand from anchor investors exceeds the available anchor portion, the merchant bankers cannot give everyone what they asked for. So they scale down, or cut back, each anchor's allotment to fit the size of the pie. An investor who applied for a large amount in a heavily sought-after issue may end up with a meaningfully smaller allocation.

The cut-back is, in effect, the anchor-segment version of oversubscription rationing. It is a sign of strong institutional appetite, exactly the kind of demand that often precedes a healthy listing.

Why it should be on your radar

As a retail investor you don't participate in the anchor round, but its outcome is public and informative. A fully subscribed anchor book that required cut-backs, populated by reputable long-only funds, tells you serious institutions wanted in and were willing to be rationed. Anchor allotments also carry lock-ins (a phased structure, with part locked for 30 days and part for 90 days), which discourages immediate post-listing exits and supports orderly trading.

Takeaway: when you study an upcoming IPO, read the anchor allotment disclosure closely. Heavy demand that forced cut-backs, especially among quality domestic mutual funds, is a useful, if imperfect, vote of institutional confidence, and the staggered anchor lock-ins give you a sense of when early institutional selling pressure might surface after listing.
