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 any time 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 (INDEX: ^FTSE) 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 BT Group (LSE: BT-A.L) (NYSE: BT), whose infrastructure remains at the heart of the UK's telecoms network but has struggled to deliver the growth expected by investors in recent years.

Dialing a wrong number?
These numbers show how BT has performed against the FTSE 100 over the last 10 years:

Total Return

2007

2008

2009

2010

2011

Trailing-10-Year Average

BT (4.4%) (44.6%) 2.4% 39.1% 9.8% 5.5%
FTSE 100 7.4% (28.3%) 27.3% 12.6% (2.2%) 7.6%

Source: Morningstar. Total return includes both changes to the share price and reinvested dividends. These two ingredients combined are what make it possible for equity portfolios to regularly outperform cash and bonds over the long term.

After suffering very badly in 2007-2008, BT was slower to recover than the wider market in 2009 but since appears to have turned a corner. BT's 10-year average trailing return still lags that of the FTSE 100, however.

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 BT shapes up:

Basics:

Year Founded 1981*
Market Cap 19 billion pounds
Net Debt 10.2 billion pounds
Dividend Yield 3.5%

Sources: Morningstar, Digital Look, and BT Group. *1981 was the year when the British Telecommunications Act led to the creation of the telecoms function from the Post Office. In 1982, BT was privatized. Prior to this, the Post Office had been the monopoly supplier of U.K. telecoms services since 1912.

Five-Year Average Financials:

Operating Margin 11.6%
Interest Cover 3.2 times
EPS Growth 2.8% (adj.)
Dividend Growth 12%
Dividend Cover 2.2 times

Sources: Morningstar, Digital Look, and BT Group.

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

Criteria

Comment

Score

Longevity As a commercial organization, it's not that old. 3/5
Performance vs. FTSE Pretty mediocre. 3/5
Financial strength A whopping pension deficit and net gearing of 782% aren't great. 2/5
EPS growth Lackluster growth is one of BT's problems. 3/5
Dividend growth Dividends are growing again but are only just over half 2008 levels. 3/5

Total: 14/25

BT's score of 14/25 may seem a little harsh, but I don't find BT particularly attractive when compared to fellow FTSE 100 member Vodafone, which trades on a slightly higher valuation but offers a much greater dividend yield, stronger finances, and a better track record of growth.

BT is still paying the price for its debt-fueled expansion in the 1990s, which resulted in it flogging its Yell and O2 businesses in order to stay afloat. It has struggled to deliver significant growth over the last decade, although there are now signs of a possible turnaround, as its triple-play offering (telephone, broadband, and television) is becoming increasingly strong. However, BT has already spent 890 million pounds this year on the broadcasting rights to soccer and rugby matches, so it is banking on continued subscriber growth for BT Vision, its television service.

Expert selections

Doing your own research is important, but another good way of identifying great dividend-paying shares is to study the choices of successful professional investors. Interestingly, BT is currently one of the largest shareholdings of Neil Woodford, who manages more money for private investors than any other City manager -- he had 20 billion pounds under management at the end of January 2012.

Woodford's dividend stock picks outperformed the wider index by a staggering 305% in the 15 years ending Dec. 31, 2011, and you can learn about his top holdings and how he generates such fantastic profits in this free Motley Fool report.
