Tangible non-current asset assertions

Dear Tutor,

I’m currently going through questions in BPP’s Practice & Revision Kit and questions 118 has left me confused.

“Which of the following assertions are relevant to the audit of tangible non-current assets.

(1) Existence
(2) Occurrence
(3) Classification
(4) Presentation

A. 1 only
B. 1,3 and 4
C. 2,3 and 4
D. 1,2,3 and 4”

I thought the assertions relating to assets were completeness,obligation and rights, valuation and allocation, existence and presentation. I am stumped as there was no option for 1 and 4. However, the answer says that option B is correct, but doesn’t classification relate to transactions and events.

Would you be able to explain why classification is also a correct assertion?
