1. | STATUTORY INFORMATION

| Mainframe Computer Services Group Limited is a private company, limited by shares , registered in England and Wales. The company's registered number and registered office address can be found on the Company Information page.

2. | ACCOUNTING POLICIES

| Basis of preparing the financial statements

| These financial statements have been prepared in accordance with Financial Reporting Standard 102 "The Financial Reporting Standard applicable in the UK and Republic of Ireland" including the provisions of Section 1A "Small Entities" and the Companies Act 2006. The financial statements have been prepared under the historical cost convention.

| Turnover

| Turnover is measured at the fair value of the consideration received or receivable, excluding discounts, rebates, value added tax and other sales taxes.

| Intangible assets

| Intangible assets are initially measured at cost. After initial recognition, intangible assets are measured at cost less any accumulated amortisation and any accumulated impairment losses.

| Patents and licences are being amortised evenly over their estimated useful life of nil years.

| Tangible fixed assets

| Depreciation is provided at the following annual rates in order to write off each asset over its estimated useful life.

| Plant and machinery etc | - | 25% on reducing balance and 15% on reducing balance

| Taxation

| Taxation for the year comprises current and deferred tax. Tax is recognised in the Statement of Income and Retained Earnings, except to the extent that it relates to items recognised in other comprehensive income or directly in equity.

| Current or deferred taxation assets and liabilities are not discounted.

| Current tax is recognised at the amount of tax payable using the tax rates and laws that have been enacted or substantively enacted by the statement of financial position date.

| Deferred tax

| Deferred tax is recognised in respect of all timing differences that have originated but not reversed at the statement of financial position date.

| Timing differences arise from the inclusion of income and expenses in tax assessments in periods different from those in which they are recognised in financial statements. Deferred tax is measured using tax rates and laws that have been enacted or substantively enacted by the year end and that are expected to apply to the reversal of the timing difference.

| Unrelieved tax losses and other deferred tax assets are recognised only to the extent that it is probable that they will be recovered against the reversal of deferred tax liabilities or other future taxable profits.

| Hire purchase and leasing commitments

| Rentals paid under operating leases are charged to profit or loss on a straight line basis over the period of the lease.

| Pension costs and other post-retirement benefits

| The company operates a defined contribution pension scheme. Contributions payable to the company's pension scheme are charged to profit or loss in the period to which they relate.
