STATEMENT REGARDING COMPUTATION OF RATIO OF EARNINGS TO COMBINED FIXED CHARGES AND PREFERENCE DIVIDENDS

The following table reflects the computation of the ratio of earnings to combined fixed charges and preference dividends for the periods presented (in thousands, except for ratios):

				Year Ended June 30,
	9 months ended March 31, 2016			2015			2014		2013		2012		2011
Computation of earnings:
Earnings before taxes		218,791			266,044			276,535		178,210		137,345		136,134
Add:
(Income) losses attributable to non-controlling interests		(75	)		(79	)		51		—		—		—
Fixed charges (see below)		54,461			54,620			27,934		16,982		15,564		8,452
		273,177			320,585			304,520		195,192		152,909		144,586
Computation of combined fixed charges and preference dividends:
Fixed charges:
Interest expense		54,461			54,620			27,934		16,982		15,564		8,452
Preference dividends		—			—			—		—		—		—
Total combined fixed charges and preference dividends		54,461			54,620			27,934		16,982		15,564		8,452
Ratio of earnings to fixed charges (1)		5.02			5.87			10.90		11.49		9.82		17.11
Ratio of earnings to combined fixed charges and preference dividends (1) (2)		5.02			5.87			10.90		11.49		9.82		17.11

(1) For the purpose of these calculations, “earnings” is the amount resulting from adding together earnings before taxes, fixed charges, and losses attributable to non-controlling interests. “Fixed charges” includes interest expensed, capitalized and the amortization of capitalized expenses related to indebtedness.

(2) There were no preference shares outstanding for the indicated periods. Accordingly, the ratio of earnings to combined fixed charges and preference dividends was identical to the ratio of earnings to fixed charges for each period.
