 periodically reviewed to maintain homogeneity of the group and are adjusted if necessary. We use external benchmark information to supplement internal information for a particular portfolio that does not have sufficient internal data accumulated from the past experience. Credit Cards Prior to 2017, we established an allowance for the credit card portfolio using a roll-rate model. A roll-rate model is a statistical tool used to monitor the progression of loans based on aging of the balance and established loss rates. The actual loss rates derived from this model are used to project the percentage of losses within each aging category based on performance over a five-year look-back period. Basel II requires a minimum of nine years of data collection (consisting of a minimum five-year observation period for defaults and a minimum four-year observation period for post-default recoveries) as a necessary condition to using the internal model approach. After its merger with LG Card in 2007, Shinhan Card has worked to establish a risk management system and met the Basel II nine-year data collection requirement in October 2016. Through the operation of a credit review system and risk management system based on Basel II requirements, we have gained the necessary data to create internal models that can calculate PD/LGD and credit conversion factors for different groups of borrowers of financial assets. At the end of December 2016, the Financial Supervisory Service granted Shinhan Card final approval to use the internal model approach. During the first quarter of 2017, Shinhan Card completed the establishment of the IFRS loan loss calculation system, for example, by replacing Basel II risk components with risk components for financial reporting in accordance with IFRS 9, and Shinhan Card revised the calculation methodology of loan losses from a roll-rate model to an internal model approach. The internal model approach calculates separate default rates and loss given default for different groups of customers, differentiated based on the characteristics of both the customers and the products that they use. The internal model approach disaggregates customers into more than twice the number of groups than does the roll-rate model. Whereas the roll-rate model does not distinguish between customers with high and low risks of default when calculating roll rates, the internal model approach allows for a more sophisticated calculation of loan loss that reflects the customers’ credit ratings. Our general policy is to be proactive in our collection procedures, and we therefore emphasize collections at an early stage of delinquency, although we increase the level of collection efforts as the delinquency period increases with respect to the relevant account. Efforts to collect from cardholders whose account balances are up to
