American Megatrends has a strict OEM business model for AMIBIOS: it sells source code to motherboard manufacturers or customizes AMIBIOS for each OEM individually, whichever business model they require. AMI does not sell to end users, and itself produces no end-user documentation or technical support for its BIOS firmware, leaving that to licensees.

Make the check payable to: Washington State Department of Revenue. The estate has nine months from the date of death to pay tax due. If the estate tax liability is unknown at the nine month due date an estimated tax payment should be made. An extension to file does not give an estate an extension to pay. Interest accrues on any unpaid tax outstanding after the nine month due date.
