1

The second quarter of the year was marked by the completion of the second review of the economic programme, restoring business and consumer confidence, improving liquidity conditions and setting the stage for economic recovery. The Bank completed the divestment of UBB & Interlease to KBC Bank NV, in fulfillment of our commitments to DG Comp and our shareholders. The transaction generated liquidity of €0.8 billion that was utilized towards the reduction of ELA funding, currently amounting to just €2.6 billion, underscoring NBG’s comparative strength in terms of liquidity ahead of the domestic economic recovery. The completion of the recently agreed divestments of South African Bank of Athens, Ethniki Insurance, Banca Romaneasca and Vojvodjanska Banka, coupled with other initiatives, will boost our capital ratios further, while placing ELA elimination well within reach.

Asset quality developments remain encouraging; the Bank managed to reduce the stock of NPEs for a fifth consecutive quarter, adding up to a total reduction of €3.3 billion since YE’15, maintaining a €0.7 billion outperformance buffer vs its FY.17 SSM target.

Regarding operational performance, NBG managed to increase PPI by almost 20% yoy, displaying NII resilience, fee income recovery and solid cost reduction trends.

As regards capital, NBG CET1 stands at 16.5% and is set to benefit further by the completion of already agreed capital actions.

Profitability

Greece:

Q2.17 domestic core pre-provision income (PPI) reached €220m from €228m the previous quarter, reflecting a slight drop in NII (-1.3% qoq) due to deleveraging and a seasonal pick-up in OpEx (+1.1% qoq).

NII amounted to €379m from €384m in Q1.17, with the envisaged narrowing of the front-back book time deposit gap, as well as the reduction of ELA balances expected to support NII in H2.17. The additional EFSF/ESM bond disposals under the ESM bond exchange scheme resulted in NIM improving by 9bps qoq to 309bps.

Net fee and commission income remained relatively stable qoq at €53m in Q2.17, however H1.17 fees reached €107m, up by 81% yoy. Net fee growth reflects significant improvements in the Bank’s liquidity profile, including the elimination of Pillar funding costs, which resulted into a fee expense saving of €39m relative to H1.16.

Q2.17 OpEx amounted to €213m compared with €210m in Q1.17. On a H1.17 basis, operating expenses settled at €423m or 8.8% lower yoy. Cost-to-core income recovered to 49% in H1.17 from 55% in H1.16. Personnel expenses dropped by 12.6% yoy, incorporating the benefit from the Dec’16 Voluntary Exit Scheme (VES) that involved c10% of the domestic workforce. G&As declined by 2.3% yoy mainly on the back of lower expenses related to taxes and third party services.

H1.17 domestic losses after tax from continued operations amounted to €73m from €63m in H1.16, reflecting mainly increased loan impairments (+34% yoy to €431m), only partially offset by core income recovery (+19% yoy). Including on a pro-forma basis the capital gain from the sale of National Insurance Company of €144m, would have resulted in net profit amounting to €90m in Greece in H1.17.

SE Europe (1) :

In SE Europe(1), the Group recorded PAT from continued operations of €13m in H1.17 from €21m in H1.16, incorporating trading and other losses of €3m against gains of €4m a year ago.

NPEs stock declines for a 5 th  consecutive quarter

The stock of domestic NPEs contracted for a 5 th  consecutive quarter (-€0.3bn qoq), reflecting negative NPE formation despite uncertainly in Q2.17 and fully provided write-offs. The Bank has already reduced NPEs by €3.3bn since end-Q4.15, overshooting the NPE operational target by €0.7bn. Even after adjusting for write offs, NPE reduction stands at €1.5bn over the same period. The NPE ratio in Greece settled at 45.2% in Q2.17, combined with an NPE coverage of 56.2%.

Domestic 90dpd formation turned negative (-€52m), aided by a late pick-up in restructuring flows.

Q2.17 domestic provisioning run rate decreased to 257bps from 294bps in Q1.17. 90dpd coverage stood at 75.4% in Greece (74.2% at the Group level).

In SE Europe(1), the 90dpd ratio settled at 34.7% on coverage of 54.9%.

Superior liquidity position(2)

Group deposits amounted to €38.3bn in Q2.17 (+0.5% qoq), reflecting mainly the 0.4% or €0.2bn qoq increase of domestic deposits, after dropping by €0.8bn qoq in Q1.17 due to adverse seasonality. Notably, since the imposition of capital controls the Bank’s deposit base in Greece has increased by €0.9bn. In SE Europe(1) deposits increased by 1.5% qoq to €2.1bn.

Following the completion of the sale of UBB & Interlease in mid-June that generated liquidity of €0.8bn, Eurosystem funding has declined significantly to €6.8bn in August(3) from €10.2bn at end-Q1.17, with ELA down by €3.0bn over the same period to just €2.6bn. This constitutes by far the lowest exposure in the sector(2), with ELA over assets (excluding EFSF & ESM bonds) standing at just 4%. The cash value of excess collateral amounts to €10.1bn(3). Liquidity stands to improve further with the completion of the recently agreed transactions of National Insurance Company, Banca Romaneasca and Vojvodjanska Banka to the tune of c€1.7bn, reducing ELA exposure by the same amount. The execution of the remaining capital actions, as well as other initiatives, place the ELA elimination well within reach.

With ELA exposure at €2.6bn and the lowest L:D ratio among the core Greek banks(2) (85% in Greece and 86% at the Group level), NBG maintains a unique funding advantage and is well positioned to tap domestic economic recovery potential.

Capital position

CET1 ratio stood at 16.5% (4) and at 16.3%(4) on a CRD IV FL basis. The UBB & Interlease sale CET1 positive impact was partially offset by impairments on Romania and Serbia reflecting agreements to sell below book (-38bps). In H2.17, apart from the National Insurance positive capital impact, the RWA deconsolidation impact of South African Bank of Athens (S.A.B.A.), Banca Romaneasca and Vojvodjanska Banka (-€1.8bn) is expected to boost capital further.

Excluding completed and agreed transactions, equity of remaining SEE assets to be divested stands at €0.5bn on RWAs of €2.4bn.

(1)  Includes (a) the impairments on Romania and Serbia reflecting agreements to sell below book in H1.17 (€151m) and (b) a loss of €3,095m in H1.16, which reflects the recycling of losses recognized in other comprehensive income in previous periods and relates mainly to foreign currency translation differences from the translation of Finansbank’s assets and liabilities in Euro, in accordance with IFRS. This loss has already been recognized in the Group’s equity and CET1 capital in prior periods, therefore has no impact on the Group’s equity and CET1 capital
