6b) Contract price: Lc 100,000; Costs to date: Lc 60,000; Work certified Lc 50,000; Cash receive Lc 40,000; i) Prepare the contract account ii) Compute the National profit iii) How much profit should be transferred to P&L? iv) Differentiate between escalation clause and retention money?

Since the contract currently shows a notional loss of Le 10,000, no profit is transferred to the Profit and Loss account. Instead, the entire notional loss of Le 10,000 would be transferred to the Profit and Loss account as an expense.
Therefore, the amount of profit to be transferred is $\boxed{\textbf{Le 0}}$.

• Escalation Clause: This is a provision in a contract that allows for an adjustment in the contract price. It is typically included to protect the contractor from unforeseen increases in the cost of materials, labor, or other specified expenses during the contract period. If costs rise beyond a certain threshold, the contract price can be increased accordingly.
• Retention Money: This refers to a portion of the payment that the client withholds from the contractor until the contract is fully completed and any defects or issues identified during a specified period (known as the defects liability period) have been rectified. It serves as a security for the client to ensure satisfactory completion of work and to cover potential costs of rectifying defects.
