LONDON -- The last five years have been tough for those in retirement. Portfolio valuations have been hammered and annuity rates have plunged. There's no sign of things improving anytime soon, either, as the eurozone and the U.K. economy look set to muddle through at best for some years to come.

A great way of protecting yourself from the downturn, however, is by building your retirement fund with shares of large, well-run companies that should grow their earnings steadily over the coming decades. Over time, such investments ought to result in rising dividends and inflation-beating capital growth.

In this series, I'm tracking down the U.K. large caps that have the potential to beat the FTSE 100 over the long term and support a lower-risk income-generating retirement fund (you can see the companies I've covered so far on this page).

Today, I'm going to take a look at Imperial Tobacco Group (LSE: IMT.L), the U.K.'s second-largest tobacco company.

Does Imperial beat the index?
To start with, let's take a look at how Imperial Tobacco has performed against the FTSE 100 over the last 10 years, on a total return basis:

Imperial Tobacco has outperformed the FTSE 100 over the last 10 years, delivering an average of 3% extra total return each year. However, Imperial's larger U.K. peer, British American Tobaccohas delivered much greater returns, highlighting the benefits of its greater focus on emerging markets.

What's the score?
To help me pinpoint suitable investments, I like to score companies on key financial metrics that highlight the characteristics I look for in a retirement share. Let's see how Imperial Tobacco shapes up:

Here's how I've scored Imperial Tobacco on each of these criteria:

A genuine blue chip.

Performance vs. FTSE

It's beaten the index over the last 10 years.

OK, but quite a lot of debt and falling margins.

Slowing, but remaining ahead of inflation.

Robust and attractive.

Total: 20/25

Imperial Tobacco's score of 20 out of 25 suggests that it could be a strong candidate for a retirement fund portfolio. However, Imperial is playing catch-up with British American Tobacco in emerging markets and is struggling to maintain its margins in mature and more heavily-regulated Western markets.

My choice of tobacco share would be BAT, which I feel offers better growth prospects and a more reliable income than Imperial. On the other hand, Imperial currently trades on a fairly attractive P/E ratio of 12.2, making it significantly cheaper than BAT's P/E of 16.4.

Both shares are attractive investments, and you may be interested to learn that both Imperial and BAT account for a big portion of City legend Neil Woodford's funds -- the man many see as the U.K.'s answer to Warren Buffett.

Woodford's other shares
Neil Woodford's dividend stock picks outperformed the wider index by a staggering 305% in the 15 years to Dec. 31, 2011, and he now manages more money for private investors than any other City manager.
