Chao Yuen Ren (1892–1982)
No full textY. R. Chao is easily the most famous linguist to have come out of China. Born before the end of the last dynasty in China, he received a traditional Confucian education, but was also one of the first Chinese people to be sent to the West for training in modern Western science (under the Boxer Indemnity Fund). The remarkable breadth and scope of his studies included physics, mathematics, linguistics, musical and literary composition, and translation, and he was a pioneer in many of these fields

Equity valuation: REN - Redes Energéticas Nacionais, SGPS, S.A.
No full textO presente trabalho de projeto de mestrado tem por objetivo determinar o valor mais realista e
rigoroso possível das Redes Energéticas Nacionais, SGPS, S.A. (REN), definindo um price
target das ações do grupo para a data de 31 de Dezembro de 2015. A REN é a entidade
detentora das concessões de serviço público para o transporte de eletricidade e gás natural no
território português.
Com vista a atingir o objetivo determinado, foi realizada uma apresentação das diferentes
metodologias de avaliação de empresas com base nas melhores práticas e nos estudos levados
a cabo pelos autores mais prestigiados da área. Dadas as características da REN e o propósito
da avaliação, foi definido que a metodologia mais apropriada seria o método Discounted Cash
Flow to the Firm (DCFF).
O estudo da REN e do contexto macroeconómico, energético e regulamentar, levou à projeção
da atividade do grupo num periodo de 10 anos. As alterações no modelo regulatório
introduzidas em 2009 e a recente reprivatização do grupo proporcionaram melhores condições
para o investimento e perspetivas de crescimento. Na atividade de transporte de gás natural, a
REN encontra-se ainda numa fase inicial, estando previstos investimentos consideráveis nos
próximos anos. Devido ao contexto macroeconómico, entre outros diversos fatores, o grupo
tem vindo a reduzir as suas necessidades de Fundo de Maneio, sendo contudo esperado para
os próximos anos uma inversão desta tendência, requerendo investimentos que terão um
impacto negativo nos Free Cash Flows (FCF), especialmente no segmento da eletricidade.
Os resultados alcançados através do método DCF apontam para que as ações da REN a 31 de
Dezembro de 2015 (2,78 €) se encontrem cotadas abaixo do seu valor, que foi calculado em
2,86 € por ação.This project aims to achieve a realistic and rigorous valuation of Redes Energéticas
Nacionais, SGPS, S.A. (REN), setting a price target for the group’s shares on December 31,
2015. REN is the holder of the public service concessions for electricity and natural gas
transmission in the Portuguese territory.
In order to perform the most possible accurate valuation, different valuation methodologies
were presented based on the best business practices and studies undertaken by the most
prestigious authors of the area. Given the characteristics of REN and the purpose of the
evaluation, it was decided that the most appropriate methodology was Discounted Cash Flow
to the Firm (DCFF), discounting cash flows separately for each of the segments of the group.
The study of REN and the macroeconomic, regulatory and energy contexts led to the
projection of the group’s activity. Changes in the regulatory model introduced in 2009 and the
recent privatization of the group provided better conditions for investment and growth
prospects. In the natural gas transmission activity, REN is still at an early stage, whereby
considerable investments are foreseen in the coming years. Over the last years, the group has
reduced its working capital needs due to the macroeconomic context and other factors,
however it is expected for the coming years a reversal of this trend, requiring investments that
will have a negative impact on the Free Cash Flows (FCF), mainly in the electricity sector.
The results achieved through the application of the DCF method indicate that REN shares in
31 December 2015 (2,78€) are being traded below their value, which has been calculated in
2,86 € per share
