Management discussion and analysis

General

The unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“USGAAP”). The preparation of financial statements in conformity with USGAAP requires management to make estimates and assumptions that reported amounts of assets and liabilities at the date of the financial statements and the amount of expenses reported during the period. Actual results could differ from those estimates. Unless otherwise indicated, all financial information presented in HK$ may be converted to US$ using the exchange rate of 7.8 HK$ for every 1 US$.

Results of Operations

Operating results for the first quarter ended March 31, 2015 compared to the first quarter ended March 31, 2015

We recorded an approximately 6.8% increase in revenue for the first quarter ended March 31, 2015 to HK$292.9 million compared to the corresponding period in the prior year. The increase in revenue was primarily a result of our continued focus on soliciting new orders from existing customers as well as new customers.

Our gross profit increased by approximately 12.6% to HK$74.0 million compared to the corresponding period in the prior year. The increase in gross profit was attributable to better margins on our products compared to the corresponding period in the prior year, and also our on-going efforts in streamlining our manufacturing operation and process. Gross profit margin improved to 25.3% from 24.0% compared to the corresponding period in the prior year.

We recorded an approximately 37.9% decrease in income before income tax expenses for the first quarter ended March 31, 2015 to HK$41.9 million compared to the corresponding period in the prior year. The decrease was mainly attributable to a one-off gain on disposal of a subsidiary for HK$32.2 million recorded in the corresponding period in the prior year. Excluding the effect of this prior corresponding period one-off transaction, our normal operating income before income tax actually increased by approximately 18.5% instead.

Income tax expense was HK$6.9 million compared to HK$6.0 million in the corresponding period in the prior year, arising from an increased normal operating income. Excluding the effect of the aforesaid prior corresponding period one-off transaction, our effective income tax rate was 16.6% compared to 17.0% in the corresponding prior year period and our net income after tax was HK$35.0 million, an increase by approximately 19.0% compared to the corresponding period in the prior year.

Balance sheet positions as at March 31, 2015 compared to December 31, 2014

Total assets increased by HK$29.4 million or approximately 2.3% to HK$1,300.6 million as of March 31, 2015 compared to HK$1,271.2 million as of December 31, 2014. This increase was mainly attributed to a HK$21.8 million increase in cash and cash equivalent and a HK$15.4 million increase in deposits, prepayment and other receivables, against a HK$7.9 million decrease in inventories.

Total liabilities increased by HK$9.8 million or approximately 2.9% to HK$348.0 million as of March 31, 2015 compared to HK$338.2 million as of December 31, 2014. This increase was mainly attributable to a HK$20.2 million dividend payable and a HK$3.4 million increase in tax payable, against a HK$15.3 million decrease in trade payables.

Cashflow analysis

We have relied primarily upon internally generated funds and bank borrowings to finance our operations and expansion.

For the three months ended March 31, 2015, we recorded HK$17.0 million cash inflow as compared to HK$98.9 million cash inflow in the same corresponding period in the prior year, which included HK$46.1 million proceeds from the disposal of a subsidiary in that prior period.

We generated HK$43.6 million cash inflow from operating activities as compared to HK$68.3 million cash inflow in the same corresponding period in the prior year. Net cash used in investing activities was HK$26.6 million compared to net cash inflow of HK$34.8 million in the corresponding period in the prior year which included HK$46.1 million proceeds from the disposal of a subsidiary.

Cash and cash equivalent amounted to HK$550.3 million as of March 31, 2015, which we utilized to settle the dividend payables of HK$20.2 million, as declared in April 2015, in May 2015.

Off-Balance Sheet Arrangements

The Company has not entered into any financial guarantees or other commitments to guarantee the payment obligations of third parties. The Company has not entered into any derivative contracts that are indexed to its shares and classified as shareholder’s equity or that are not reflected in its combined financial statements. Furthermore, the Company does not have any retained or contingent interest in assets transferred to an unconsolidated entity that serves as credit, liquidity or market risk support to such entity. The Company does not have any variable interest in any unconsolidated entity that provides financing, liquidity, market risk or credit support to it or that engages in leasing, hedging or research and development services with the Company. There are no off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on the Company’s financial condition, net sales or expenses, results of operations, liquidity, capital expenditures or capital resources that are material to an investor.
