[WIP]Story: Warehouse lending

A liquidity provides a line of credit to originator, with optional
- interest charge for cash drawn
- premium fee charge for the un-used balance
originator will use the fund to buy assets ( during SPV ramp up period )
Once certain condition met, the SPV will end ramp up period and enter amortizing or revolving period
- the SPV will issue bonds and get proceeds
- the proceeds will pay off outstanding balance of liquidity provider
- The SPV will "own" the new assets on cutoff date

asset ramping up
- the availability of assets ? -> revolving asset curve in the assumption
- quality of asset bought ? -> revolving asset perf assumption
ramping waterfall
- waterfall can be run different frequency -> separated defined in ramp status
- how much to draw ? defined in waterfall draw action, with a formula
Financing cost
- interest on balance drawn and un-drawn -> already modeled by liquidity facility
when ramping is ended ?
- ended by a Pre ?( modeled as trigger ? or supply with an run assumption separately )
How to sell the assets to SPV ?
- using Pricing Method ?
- how to handle accrued interest ?
How to determine the size of issuance ?
- user can model bonds & cap structure in the deal object, but if the size of bond depends pool size ?

Deal Object
- Date for ramping period : (Begin Date , , , )
- Waterfall : a new waterfall for ramping up period
- Trigger : a Pre which will trigger the Closing event
Pool Flow
- There should be a optional change in the pool collection rule which targets to different collection account
In Deal Run
- populate new action dates and insert to deal run context
- build issuance balance
- sell notes with proceeds and buy assets
- repay balance of warehouse lenders
