S&P Global Ratings —A brief description of the applicable S&P Global Ratings, a subsidiary of S&P Global Inc. previously McGraw Hill Financial, Inc. (“Standard & Poor’s” or “S&P”), rating symbols and their meanings (as published by S&P) follows:

An S&P Global Ratings issue credit rating is a forward-looking opinion about the creditworthiness of an obligor with respect to a specific financial obligation, a specific class of financial obligations, or a specific financial program (including ratings on medium-term note programs and commercial paper programs). It takes into consideration the creditworthiness of guarantors, insurers, or other forms of credit enhancement on the obligation and takes into account the currency in which the obligation is denominated. The opinion reflects Standard & Poor’s view of the obligor’s capacity and willingness to meet its financial commitments as they come due, and this opinion may assess terms, such as collateral security and subordination, which could affect ultimate payment in the event of default. NR indicates that a rating has not been assigned
