CREDITORS HIERARCHY

Hello sir,

Please correct me if i am wrong, can we say that in company’s point of view from high risk to low risk it can be classified as below:

1- equity
2- preference share (equity)
3- unsecure debts
4- secure debts

And in investors point of view it is:
high risk to low risk
1- equity
2- preference share (equity)
3- unsecure debts
4- secure debts

Thanks
