OREANDA-NEWS. Fitch Ratings has assigned an 'AA+' rating to Microsoft Corporation's (Microsoft) $13 billion senior notes offering. Pro forma for the senior notes issuance, Fitch's ratings affect $51.7 billion of total debt. A full list of current ratings follows at the end of this release.

KEY RATING DRIVERS

Microsoft issued $13 billion of senior notes with various maturities to be used for general corporate purposes. Fitch expects Microsoft will use net proceeds mainly for stock buy backs given the company's plan to complete the $17.9 billion remaining under the current $40 billion share repurchase authorization by Dec. 31, 2016.

Microsoft has $99.4 billion in cash and short-term investments but only $3.4 billion of cash and short-term investments were held in the U.S. as of Sept. 30, 2015. Fitch expects incremental debt to fund domestic cash requirements including aggressive shareholder returns, given the company's reluctance to repatriate foreign earnings, resulting in weak total leverage (total debt to operating EBITDA) for the rating.

Nonetheless, Fitch expects supplemental adjusted net leverage, which nets adjusted offshore cash and investments against debt balances, will remain below 1.5x. Fitch estimates supplemental adjusted net leverage was roughly 1x for the latest 12 months (LTM) ended Sept. 30, 2015, pro forma for the new senior notes.

KEY RATING DRIVERS

The ratings and Outlook are supported by:

--Fitch's expectations that Microsoft Windows will remain the primary operating system (OS) for servers and PCs, despite lackluster adoption of Windows 8 and 8.1 for PCs, supporting significant annual free cash flow (FCF).

--Microsoft's recurring revenue base related to long-term commercial licensing agreements, which represents more than half of total revenues.

--Fitch's expectations that increasing adoption of enterprise cloud services will further diversify Microsoft's revenue base and increase profitability, reducing the company's exposure to the less defensible and profitable consumer PC market.

Ratings concerns center on Fitch's expectations that:

--Microsoft will continue relying on the PC market for the vast majority of FCF, although Fitch expects faster growing cloud services could reduce this risk over the longer term.

--Competing free or lower cost operating systems may continue reducing Microsoft's share, primarily in consumer and education markets. Microsoft competes with Google in the tablet and smartphone markets (Android - roughly 80%) and in the notebook PC market (Chrome).

--Success in smartphone and tablet markets could remain modest (below 5% share), despite significant investments and resource allocation.

--Sustained consumer PC demand weakness, with the exception of Office 365 (SaaS), driven by extended PC replacement cycles from tablet and smartphone substitution.

--Significant dividend and share repurchase programs are likely to continue pressuring the company to issue debt to avoid repatriation of foreign earnings.

KEY ASSUMPTIONS

Fitch's key assumptions within the rating case for the issuer include:

--$17.9 billion of share buybacks by the end of December 2016.
--Microsoft does not repatriate overseas cash to the United States.
--Annual FCF of $12 billion - $15 billion.
--Capital spending will remain elevated to support cloud infrastructure development.
--Dividends between $10 billion and $12 billion over the ratings horizon.

RATING SENSITIVITIES

Negative: Future developments that may, individually or collectively, lead to negative rating action include:

--Fitch's expectations that supplemental adjusted net leverage (total debt netted against adjusted cash and investments held outside the U.S.) above 1.5x from significant debt issuance to support shareholder returns.

--Material profit margin erosion related competitive pressures, including strong commercial adoption of the public cloud and/or open-sourced software materially reduces demand for key Microsoft products; penetration of alternative operating systems in the PC market or market share gains by Apple; or greater acceptance of cheaper software applications that compete with Microsoft Office.

Positive rating actions are unlikely in the absence of material diversification, driven by solid organic growth in non-PC businesses.

LIQUIDITY

As of Sept. 30, 2015, Fitch believes liquidity is very strong and supported by:
--$99.4 billion of cash and short-term investments, of which $3.4 billion was in the U.S.;
--An undrawn $5 billion revolving credit facility (RCF) expiring Nov. 14, 2018 and an undrawn $5 billion RCF expiring Nov. 4, 2015, both of which backstop the company's commercial paper (CP) program;
--Fitch's expectation for $12 billion to $15 billion of annual FCF also supports liquidity.

Pro forma for the senior notes issuance, total debt was $28.6 billion at Sep. 30, 2015 and consisted of various tranches of senior notes with staggered debt maturities and $5 billion of CP borrowings. Microsoft's nearest debt maturity, aside from CP borrowings, is $750 million of senior notes due Feb. 8, 2016.
