| 1 | The Group did not conduct fair value estimation since the book amount is a reasonable approximation of the fair value.
| 2 | Equity instruments that do not have a quoted price in an active market are measured at cost because their fair value cannot be measured reliably and excluded from the fair value disclosures.
| 36.2 | Financial Instruments Measured at Cost
Available-for-sale financial assets measured at cost as of December 31, 2016 and 2017, are as follows:
(In millions of Korean won) |  | 2016 |  |  | 2017 |
K-Bank |  | ￦ | 36,500 |  |  | ￦ | — |
IBK-AUCTUS Green Growth Private Equity Fund |  |  | 9,506 |  |  |  | 8,518 |

|  | ￦ | 105,773 |  |  | ￦ | 61,551 |
The range of cash flow estimates is significant and the probabilities of the various estimates cannot be reasonably assessed and therefore, these instruments are measured at cost. The Group does not have any plans to dispose of the above-mentioned equities instruments in the near future. These instruments will be measured at fair value when the Group can develop a reliable estimate of the fair value.
| 36.3 | Fair Value Hierarchy
Assets measured at fair value or for which the fair value is disclosed are categorized within the fair value hierarchy, and the defined levels are as follows:
| • |  | Quoted prices (unadjusted) in active markets for identical assets or liabilities (Level 1).
| • |  | Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (that is, prices) or indirectly (that is, derived from prices) (Level 2).
| • |  | Inputs for the asset or liability that are not based on observable market data (that is, unobservable inputs) (Level 3).
Fair value hierarchy classifications of the financial assets and financial liabilities that are measured at fair value or its fair value is disclosed as of December 31, 2016 and 2017, are as follows:

| 36.6 | Valuation Processes for Fair Value Measurements Categorized Within Level 3
The Group uses external experts that perform the fair value measurements required for financial reporting purposes. External experts report directly to the chief financial officer (CFO), and discusses valuation processes and results with the CFO in line with the Group’s reporting dates.
| 36.7 | Gains and losses on valuation at the transaction date
In the case that the Group values derivative financial instruments using inputs not based on observable market data, and the fair value calculated by the said valuation technique differs from the transaction price, then the fair value of the financial instruments is recognized as the transaction price. The difference between the fair value at initial recognition and the transaction price is deferred and amortized using a straight-line method by maturity of the financial instruments. However, in the case that inputs of the valuation techniques become observable in markets, the remaining deferred difference is immediately recognized in full in profit for the year. In relation to this, details and changes of the total deferred difference for the years ended December 31, 2016 and 2017, are as follows:
