|  | Balance as of December 31, 2018 |  |  | Balance as of December 31, 2017 |
|  | Assets |  |  | Liabilities |  |  | Assets |  |  | Liabilities |
Derivatives - cash flow hedge |  |  | 11,571 |  |  |  | 279,152 |  |  |  | 8,230 |  |  |  | 329,731 |
The derivatives are primarily interest rate cash-flow hedges. All are classified as non-current assets or non-current liabilities, as they hedge long-term financing agreements. Additionally, the Company owns currency options with leading international financial institutions, which guarantee minimum Euro-U.S. dollar exchange rates. The strategy of the Company is to hedge the exchange rate for the distributions from its Spanish assets after deducting euro-denominated interest payments and euro-denominated general and administrative expenses. Through currency options, the strategy of the Company is to hedge 100% of its euro-denominated net exposure for the next 12 months and 75% of its euro denominated net exposure for the following 12 months, on a rolling basis. As stated in Note 3 to these consolidated financial statements, the general policy is to hedge variable interest rates of financing agreements purchasing call options (caps) in exchange of a premium to fix the maximum interest rate cost and contracting floating to fixed interest rate swaps. As a result, the notional amounts hedged, strikes contracted and maturities, depending on the characteristics of the debt on which the interest rate risk is being hedged, can be diverse:
· | Project debt in Euros: the Company hedges between 81% and 100% of the notional amount, maturities until 2030 and average guaranteed interest rates of between 0.60% and 4.87%.
· | Project debt in U.S. dollars: the Company hedges between 70% and 100% of the notional amount, including maturities until 2034 and average guaranteed interest rates of between 2.32% and 5.27%.
The table below shows a breakdown of the maturities of notional amounts of derivatives designated as cash flow hedges as of December 31, 2018 and 2017.

The table below shows a breakdown of the maturity of the fair values of derivatives designated as cash flow hedges as of December 31, 2018 and 2017. The net position of the fair value of caps and swaps for each year end reconciles with the net position of derivative assets and derivative liabilities in the consolidated statement of financial position:
Fair value |  | Balance as of December 31, 2018 |  |  | Balance as of December 31, 2017 |
|  | Cap |  |  | Swap |  |  | Cap |  |  | Swap |
Up to 1 year |  |  | 493 |  |  |  | (11,848 | ) |  |  | 347 |  |  |  | (13,224 | )
Between 1 and 2 years |  |  | 2,172 |  |  |  | (13,231 | ) |  |  | 978 |  |  |  | (14,378 | )

Subsequent years |  |  | 8,344 |  |  |  | (238,922 | ) |  |  | 6,509 |  |  |  | (286,206 | )
Total |  | $ | 11,571 |  |  |  | (279,152 | ) |  | $ | 8,230 |  |  |  | (329,731 | )
During 2018, fair value of derivatives increased mainly due to an increase in the fair value of interest rate cash-flow hedges resulting from the increase in future interest rates. The net amount of the fair value of interest rate derivatives designated as cash flow hedges transferred to the consolidated income statement in 2018 is a loss of $67,519 thousand (loss of $70,953 thousand in 2017 and a loss of $72,774 thousand in 2016). Additionally, the net amount of the time value component of the cash flow derivatives fair value recognized in the consolidated income statement for the year 2018, 2017 and 2016 has been a loss of $560 thousand, a loss of $860 thousand and a gain of $1,694 thousand respectively. The after-tax result accumulated in equity in connection with derivatives designated as cash flow hedges at the years ended December 31, 2018 and 2017, amount to a $95,011 thousand gain and a $80,968 thousand gain respectively.
