To run on the latest to occur of...

[xReindeer]

Please help me figure out what this sentence means.

The delivery time shall start to run on the latest to occur of
(a) the date of execution of the Agreement by Seller;
(b) the date of receipt by Seller of the agreed down payment as set forth in the Agreement; or;
(c) the date of receipt by Seller of all agreed information and approval by Buyer of the general arrangement drawings


The problem is what the meaning 'The delivery time shall start to run on the latest to occur of' should have?
Does it mean .. whichever is later ?
How is this sentence structured?

Thank you in advance

Yes, it appears to mean that the "delivery time" only begins when the last of those three events occurs. In that case, the delivery time must be in the form of a time period (eg. four weeks) rather than a date.
It's badly expressed.
