How the uplift is calculated. Uplift = volume × (ARP rate − Barq's sourcing cost) ÷ mid-market. ARP rate = mid + the selected premium; Barq's sourcing cost = mid − the assumed spread. SAR is pegged to USD at 3.75, so ARP prices the USD/INR leg and expresses it as SAR/INR. Rates are point-in-time (13 Aug 2026); refresh at quote time.
The assumption, stated plainly: Barq's observed customer rate is 25.1876 (≈101 bps below mid). We assume ~80 bps of that is Barq's own FX revenue, which it keeps unchanged, implying a sourcing cost of ~30 bps below mid. This simulator compares ARP only against that sourcing cost — so the uplift shown is incremental margin, not a claim on revenue Barq already earns.
