Financial Risk Management	Note 5 - Financial Risk Management Risk management framework The Board of Directors has overall responsibility for the establishment and oversight of the Group’s financial risk management framework. The Board has established a sub-committee for financial exposures management, which is responsible for developing and monitoring the Group’s financial exposures management policies. The sub-committee recommends to the Board of Directors changes in the Group's financial exposures management policy. The Group’s risk management policies are established to identify and analyze the financial risks faced by the Group, to set appropriate risk limits and controls, and to monitor risks and adherence to limits. Risk management policies and systems are reviewed regularly to reflect changes in market conditions and the Group’s activities. The Financial Disclosures Committee oversees how management monitors compliance with the Group’s financial risk management policies and procedures, and reviews the adequacy of the financial risk management framework in relation to the risks faced by the Group. See also Note 24, regarding Financial Instruments. Credit risk Management has a credit policy in place and the exposure to credit risk is monitored on an ongoing basis. The Group's credit risk arises principally from the Group's receivables from customers and investments in debt instruments. The carrying amounts of financial assets and contract assets represent the Group's maximum credit risk exposure. Trade receivables, other receivables and contract assets The Group conducts credit evaluations on receivables over a certain amount, and requires financial guarantees against them, according to the risk level of each customer. Management monitors outstanding receivable balances and credits appropriate allowances for irrecoverable amounts included in the financial statements which adequately reflect the loss embodied in irrecoverable debts. The Group is exposed to credit risk arising mainly from its operation in Israel. Cash and cash equivalents Most of the Group’s cash and cash equivalents are maintained with major banking institutions in Israel. Investments in debt instruments The Group limits its exposure to credit risk by investing only in liquid debt instruments and only with counterparties that have a credit rating of at least "AA-" from S&P Maalot. Management actively monitors credit ratings and given these high credit ratings, management does not expect any counterparty to fail to meet its obligations. During the reporting period, the Company realized the investment portfolio in full. Derivatives The counterparties of the derivatives held by the Group are major banks in Israel. At the reporting date, there were no significant concentrations of credit risk. The maximum exposure to credit risk is represented by the carrying amount of each financial asset, including derivatives, in the consolidated statement of financial position. Financial instruments that could potentially subject the Group to credit risks consist primarily of trade receivables. Credit risk with respect to these receivables is limited due to the composition of the subscriber base, which includes a large number of individuals and businesses. Assessment of expected credit losses for corporate customers The Group allocates each exposure to a credit risk grade based on data that is determined to be predictive of the risk of loss and applying experienced credit judgement. Credit risk grades are defined using quantitative and qualitative factors that are indicative of the risk of default. Assessment of expected credit losses for individual customers The Group uses a provision matrix that is based on, inter alia, an aging of trade receivables, to measure the expected credit losses from individual customers, which comprise a very large number of small balances. Loss rates are calculated based on the probability of a receivable progressing through successive stages of delinquency to write-off. The loss rates are calculated separately for exposures in different segments based on the following common credit risk characteristics – age of debt and period of delinquency, geographic region, age of customer relationship and type of product purchased. Liquidity risk The Group's approach to managing liquidity is to ensure, as far as possible, that it will always have sufficient liquidity to meet its liabilities when due, under both normal and extreme conditions, without incurring unacceptable losses or risking damage to the Group's reputation. The cash surpluses held by Group that are not required for financing their current activity, were invested in interest-bearing investment channels such as: short-term deposits and debentures. These investment channels are chosen based on future forecasts of the cash Group will require in order to meet its liabilities. During the reporting period, the investment portfolio was implemented in full. The Group examines current forecasts of its liquidity requirements so as to make certain that there is sufficient cash for its operating needs. These forecasts take into consideration matters such as the Group’s plan to use debt for financing its activity, compliance with required financial covenants, and compliance with external requirements such as laws or regulation. The Group has contractual commitments to purchase inventories and fixed assets, to incur capital expenditure with regard to its investment in a jointly controlled entity and an obligation to pay lease payments. For further information about material commitments see Note 32, regarding Commitments. Market risk In the ordinary course of business, the Group buys and sells derivatives, and also incurs financial liabilities, in order to manage market risks. All such transactions are carried out according to the policy established by the Board of Directors. Interest rate and CPI risks The Group is exposed to fluctuations in the interest rate, including changes in the CPI, as part of its borrowings are linked to the CPI. As part of its risk management policy the Group from time to time enters into forward contracts that partially hedge the exposure to changes in the CPI. All such transactions are carried out within the policy established by the Board of Directors. Currency risk The Group's operating income and cash flows are exposed to currency risk (mostly USD), mainly due to handset and network related acquisitions, purchase of TV content, purchase of telecommunications capacity and its international roaming services activity. The Group also manages bank accounts that are denominated in a currency other than its respective functional currency, primarily USD. As part of its financial exposures hedging policy, the Group uses forward and option contracts to partially hedge the exposure to fluctuations in foreign exchange rates. Capital management The Group's capital management aim is to ensure a sound and efficient capital structure which takes into consideration, among others, the following factors: A gearing ratio that supports the Group's cash flow needs with respect to its potential cash flow generation and also supporting its dividend policy, considering the limitation imposed on dividend distribution as established in the indenture of the Group's Series H - L debentures and in the Company's loan agreements, while maintaining a Net Debt to Adjusted EBITDA ratio as established in such documents, and that meets the industry standards. The Group considers Net Debt to Adjusted EBITDA ratio to be an important measure for investors, debentures holders, analysts, and rating agencies. This ratio is a non-GAAP figure not governed by International Financial Reporting Standards and its definition and calculation may vary from one company to another. The Group's debt mainly consists of short and long-term debentures traded publicly in the Tel Aviv Stock Exchange and loans from financial institutions.
