Availability is shown for the selected month. A dash means unavailable, never zero; funding or capital gaps can leave net yields pending even when gross yields are available.

How to read these figures
Borrowing costs apply to original Sky-funded principal, excluding retained and reinvested gains. Principal is assumed Sky-funded except Spark Savings. Unresolved funding splits have no borrowing-cost or net-yield estimate.
Gross yield uses investment revenue before SDE sharing. Net yield uses prime-retained venue revenue after SDE sharing, less allocation borrowing cost; it excludes prime-level adjustments and spread reimbursements. Net is therefore not simply gross minus borrowing cost.
APY annualizes the selected month’s return using average exposure. It is not a contracted or forecast rate. Monthly returns are available on each allocation page. Cash-recognized revenue can be lumpy.
These analytics do not replace settlement reports. Known-cost subtotals exclude unresolved rows and prime-level financing adjustments; they should not be read as total ilk borrowing costs.
