The OTC market is often overlooked by investors. Some of the large foreign companies are listed in the OTC markets.

When I ran my screen with the conditions:
Market Cap >= $25B
Dividend yield >=5%

the following five stocks stocks appeared in the result.

E.On AG (EONGY)
Market Cap = $63.4 B
Dividend Yield = 5.84%

RWE AG (RWEOY)
Market Cap = $40.7 B
Dividend Yield = 7.20%

BASF SE (BASFY)
Market Cap = $37.7 B
Dividend Yield = 6.03%

Telstra Corporation (TLSYY)
Market Cap = $33.0 B
Dividend Yield = 7.48%

National Australia Bank (NABZY)
Market Cap = $32.4 B
Dividend Yield = 6.17%

It is interesting to see that the top 3 companies the above list are German companies and the other two are Australian.EON and RWE are two of the largest utilities there. Of course BASF is one of the largest and well-known global chemical giant. Australia-based Telstra is a telecom services provider. National Australia Bank is one of the largest banking groups in Australia.
