Agree with Svejk - Once a company Acquires another company, it is tied in to ALL costs associated with the company - including owed monies pending payment.
Your contract will have been 'Tupe'd' across so the contract remains exactly the same, but the new company is responsible for it.
Have a read through your contract and see what it says about redundancy - it should be mentioned in there.
If not, have a look at this for advice on the 'transfer job' offered and how it may affect your redundancy offer - I take it that you have not been offered voluntary redundancy? Is it compulsory?
Please note that the new company can't make you redundant just because they have taken over your old company:

wishing you all the best (MY OH has recently been made redundant and I am expecting the same soon to come my way, so I really do wish you good luck) x
