Production volume grew y-o-y significantly from 2013 to 2014 mainly driven by border mining at IM and production ramp-up at TMU

24.6 Production

Volume mt Production Summary mt: million tons • 2014 quarterly production run rate averaged around 2.0 mn tons • Lower production in 4Q14 compared to previous quarters resulted mainly from relatively strong seasonal wet conditions • In anticipation of continued weak coal prices in 2015, the relatively higher SR in 4Q14 stemmed from higher pre-stripping activities to allow for better coal extraction in subsequent periods 1,298 2,799 4,601 6,551 1,911 4,071 6,401 8,054 15.1x 14.3x 13.7x 13.4x 13.5x 13.6x 13.2x 13.3x 0.0x 5.0x 10.0x 15.0x 20.0x 2000 4000 6000 8000 1Q13 1H13 9M13 2013 1Q14 1H14 9M14 2014 Production Volume 000 Stripping Ratio 925 1,920 3,108 4,209 1,003 2,216 3,516 4,446 16.6x 15.5x 14.4x 14.0x 14.1x 14.6x 13.8x 13.9x 0.0x 5.0x 10.0x 15.0x 20.0x 1000 2000 3000 4000 5000 1Q13 1H13 9M13 2013 1Q14 1H14 9M14 2014 Production Volume 000 Stripping Ratio ABN TMU IM PT Kutai Energi Cumulative Production Stripping Ratio Production in thousand tons Key Highlights Dump Dist. m 1,719 1,789 1,808 1,806 1,894 1,860 1,858 1,913  Yearly production rose from 4.2 mt in 2013 to 4.4 mt in 2014, while lower 4Q14 production was due to relatively strong seasonal wet conditions  2014 SR stabilized at ~13.9x  4Q14 SR rose from previous quarters due to relatively high pre-stripping to anticipate better coal extraction during continued weak coal prices in 2015 TMU ABN PT Kutai Energi Cumulative Production Stripping Ratio Production in thousand tons Key Highlights  Quarterly production run-rate stabilized at ~550K level throughout 2014, up from quarterly run-rate of ~350K throughout 2013  2014 production volume rose ~64.0 y-o-y from 1.4 mt to 2.3 mt  4Q14 production was affected by strong seasonal wet conditions  2014 SR normalized at 13.3x 278 637 976 1,401 547 1,117 1,817 2,310 11.2x 11.7x 12.8x 12.8x 13.7x 13.1x 13.2x 13.2x 0.0x 5.0x 10.0x 15.0x 20.0x 500 1000 1500 2000 2500 1Q13 1H13 9M13 2013 1Q14 1H14 9M14 2014 Production Volume 000 Stripping Ratio Dump Dist. m 1,703 1,678 1,698 1,651 1,900 1,899 1,920 1,901 ABN IM PT Kutai Energi Note: - - - Hauling road Key Highlights Cumulative Production Stripping Ratio Production in thousand tons  Post completion of hauling road at TMU to ABN in 2Q13, production run-rate significantly rose from low of 80-90K per quarter up to average ~340K throughout 2014  2014 SR stabilized at 11.8x  Strong seasonal wet weather affected 4Q14 production 84 230 505 925 362 741 1,141 1,372 11.2x 12.1x 11.2x 11.1x 11.4x 11.6x 11.6x 11.8x 0.0x 5.0x 10.0x 15.0x 20.0x 200 400 600 800 1000 1200 1400 1600 1Q13 1H13 9M13 2013 1Q14 1H14 9M14 2014 Production Volume 000 Stripping Ratio 16 2014 Financial Highlights 3 Quarterly FOB Cash Cost in USton Notes: 1 FOB Cash Cost = COGS including royalty and selling marketing expense – depreciation and amortization 2 Adj.
