RECEIVABLES FINANCE GLOSSARY

Yield and servicing reserve

DEFINITION

The yield and servicing reserve is a borrowing base deduction that covers the interest, program fees, and servicing costs that would accrue while a receivables pool winds down after a termination event or servicer replacement. Most agreements size it as the financing rate plus an assumed servicing fee, stressed, applied over a liquidation period tied to DSO.

Why a performing pool still needs this reserve

The loss and dilution reserves cover receivables that never pay. The yield and servicing reserve covers something different: the cost of time. If the facility terminates and the pool goes into run off, interest keeps accruing on the funded amount and someone must be paid to keep collecting, possibly a replacement servicer charging a market fee. Collections arrive over weeks or months, and this reserve makes sure they are enough to cover those carrying costs.

It is usually the smallest of the three main reserves, commonly 1 to 4 percent of the pool, but it moves with two things treasurers watch anyway: interest rates and DSO. A rate spike or a collections slowdown pushes it up.

How the calculation typically works

A common formulation applies a stressed rate over an assumed liquidation period, often set at 2.0x DSO to be conservative about how long run off collections would take. The yield piece uses the facility's financing rate and the servicing piece uses an assumed backup servicer fee, frequently 1.0 percent per annum for trade receivables.

YIELD AND SERVICING RESERVE CALCULATION
Input	Value
Financing rate (benchmark plus margin)	6.5%
Assumed servicing fee	1.0% per annum
Days sales outstanding (DSO)	45 days
Assumed liquidation period (2.0 x DSO)	90 days
Stress factor	1.5x
Yield reserve: 1.5 x 6.5% x 90/360	2.44%
Servicing reserve: 1.5 x 1.0% x 90/360	0.38%
Combined reserve	2.81%

On a $40,000,000 net receivables balance that is $1,124,000 held back. Formulas differ across programs: some use 1.5x DSO, some fix the liquidation period, and some carry separate reserves for fees and hedging costs. Your agreement's definitions govern.

Inputs to get right, and how Olycor handles them

DSO measured the way the agreement defines it, commonly ending receivables divided by sales in the period times days in the period, not the ERP's default formula.
The current benchmark rate as of the calculation date, since a floating rate facility reprices the reserve every period.
Consistent day count conventions: mixing 360 and 365 day bases quietly misstates the reserve.
The stress multiplier and liquidation period from the agreement, not a carried forward spreadsheet cell nobody has checked since closing.

Olycor calculates DSO from the same invoice level data that drives the rest of the certificate, pulls the configured rate and conventions for the facility, and recomputes the reserve deterministically each period. Every figure on the certificate traces back to source records, so a question about the reserve takes minutes to answer, not a day of spreadsheet archaeology.

Frequently asked questions

Why is the liquidation period a multiple of DSO?+

DSO approximates how long the pool takes to turn into cash in normal times. Run off after a termination event is assumed to be slower, because obligors pay less promptly once the relationship is winding down and a new servicer is learning the book. Multiplying DSO by 1.5x or 2.0x builds in that slowdown. The multiple is negotiated and varies by program.

Does the yield and servicing reserve count toward required credit enhancement?+

Usually not. In most trade receivables securitizations, required credit enhancement is the greater of the dynamic loss plus dilution calculation and a floor. The yield and servicing reserve sits on top of that as an additional deduction, so total reserves are enhancement plus yield and servicing.

What moves this reserve month to month?+

Three things: interest rates, DSO, and any change to the servicing fee assumption. If your DSO drifts from 45 to 55 days and the benchmark rises 100 basis points, the reserve in the example above grows from 2.81 percent to about 3.9 percent, which on a $40 million pool is roughly $430,000 of lost availability.
