Notes to the Consolidated Financial Statements (Continued)<br />

4 Critical accounting estimates and judgements (Continued)<br />

(f) Fair value of derivatives, financial assets/<br />

liabilities at fair value through profit or loss<br />

and other financial instruments<br />

The fair value of financial instruments that are not traded in an<br />

active market is determined by using valuation techniques. The<br />

Group uses its judgement to select a variety of methods and<br />

make assumptions that are mainly based on market conditions<br />

existing at each balance sheet date. The Group uses discounted<br />

cash flow analysis for various available-for-sale financial assets<br />

that were not traded in active markets.<br />

(g) Construction work<br />

(i) Revenue recognition<br />

The Group uses the percentage-of-completion method<br />

in accounting for its fixed-price contracts to deliver<br />

construction services. The use of the percentage-ofcompletion<br />

method requires the Group to estimate the<br />

services performed to date as a proportion of the total<br />

services to be performed.<br />

Estimate over the cost provision<br />

(ii)<br />

<br />

A considerable amount of judgement is required in<br />

<br />

estimating the cost provision which may have impact on<br />

<br />

profit or loss.<br />

During the year, certain cost provision has been reversed<br />

<br />

and reflected in other income.<br />

<br />

(h) Determination of fair value of share-based<br />

compensation<br />

The Group uses the Binomial Model to determine the fair value of<br />

share options issued during the year. Under this model, the value<br />

of the share options is subject to a number of assumptions such<br />

as the risk-free interest rate, the expected life of the options and<br />

historical volatility based on annualised volatility of the closing<br />

price of the share. Therefore the value may be subjective and<br />

would change should any of the assumptions change.<br />
