Aqua America Beta Estimation Fundamental Analysis Technical Analysis March 25, 2009

Since Aqua America (WTR) is a member of the S&P 400 Midcap Index and not the S&P 500 Index, I strongly
considered that each might be an appropriate independent variable against which I could regress Aqua’s returns and
determine beta. Firstly, however, the results of testing: Weekly and monthly return series regressions over one-, three-,
and five-years, and against both indices, produced low R2 and t-statistics, and negative raw betas.
1 When compared to
daily regressions, which were quite robust in terms of relevance, these data were easily discarded. Daily regressions over
each testing period produced significant results and sensible betas. Further, one-year betas produced the highest R2
statistics (and therefore the most relevant dats), so I used that series to determine beta.2
The question of “which beta” to use, then, becomes philosophical. Though the S&P 500 is traditionally used for
American companies, one may argue that WTR is better represented by a basket of more similarly sized firms. After all,
smaller companies historically have enjoyed a different risk and payoff profile than their large counterparts. Yet, WTR is
a leader in a heavily regulated, capital intensive industry, so it may compare better versus other leading firms. Ultimately,
I decided to split the difference: 50% S&P 500, 50% S&P 400 Midcap. As I noted, the data over one year proffered good
results – beta of 0.60 and R2 of 41% against the Midcap index, and 0.66 and 44%, respectively, versus the S&P 500
3 – but
my inquiry did not end there. Published betas were significantly lower than my estimate – Yahoo! Financial opined a
measly 0.07, and Thomsen-Reuters 0.29 – so I took heart in knowing that inclusion of the S&P 400 Midcap beta would
reduce my average beta. Also, with an understanding of how weekly and monthly data might vary so drastically, I felt
more confident that my beta – ultimately “smoothed” towards βM for a final estimate of 0.75 – best represents a growing,
likely-to-be-regressing (more on this later) firm whose outlook is mixed.4
True to the reputation of regulated utilities, Aqua America historically has displayed low variation of sales and
earnings.5 More importantly, it also scores low relative to other water suppliers. Sales variability is best represented by
the constant growth model (VM-est. = 0.049) while the linear model fits EBITDA variability best (VM-est. = 0.025).
Since 1999, sales have exhibited 48.8% of the variability of industry sales, and EBITDA only 9%. Perhaps not
unsurprisingly, WTR’s capital structure has not changed substantially over the test period; meanwhile, other water utilities
American States Water (AWR) and California Water Service (CWT) experienced earnings hiccups over the decade prior.
Another result of low variability has been low absolute (but not relative) business risk. This decade, Cal Water
has achieved lowest relative sales volatility and business risk, but Aqua continues to lead in marginal profitability by a
wide margin. While Cal Water sported average operating margins of 12% and American States Water 18%, Aqua set
pace at 40%. CWT and AWR also experienced negative growth in three years since 1999 versus Aqua’s unscathed
earnings record. To differentiate, then, I investigated operating leverage amongst the firms. WTR earned a group low,
1.003, implying that changes in sales and operating earnings follow a nearly one-to-one relationship. CWT scored
highest, 4.67, likely due to negative growth of operating income in 2001, 2004, and 2008; likewise, American States
scored 2.575, likely due to similarly volatile operating income.6

Aqua America’s operating performance leans heavily on its ability to produce return on fixed assets. While
capital asset turnover has slipped slightly, Aqua America has managed annual turnover variance relatively well. Next-of-
kin metric fixed asset turnover, a key figure for Aqua due to high levels of fixed plant, has also fallen, though not
significantly. The one-to-one operating leverage relationship has carried over to fixed plant and its turnover, and Aqua
appears to have managed the relationship between its assets and earnings better than AWR and CWT. Declining
turnovers, then, should not be worrisome.7
WTR and the water utilities are simultaneously improving as cash managers. On a relative basis, Aqua America
monetizes its current assets (customer billing) and pays suppliers in about 48 days – nearly twice as fast as Cal Water and
over 5 times faster than American States. Annually, Aqua has reduced its cash cycle by 2.75% since 2004, and while the
industry has tended towards faster collections – a trend expected to slow during the recession – Aqua America has
managed to extend supplier payments by 2.5%.
While solvency and liquidity are closely related, Aqua America is justifiably not as concerned about keeping a
liquid book. Since the company grows inorganically, invests heavily in infrastructure, and is so heavily regulated (and
subsidized), it does not keep much cash on hand. Accounts receivable, particularly unbilled customer accounts, have risen
5.5% on an absolute basis but have dropped nearly 4% relative to capital growth. Since inventory, consisting primarily of
materials and supplies, has de minimus operational impact, billing activities are responsible for most of Aqua’s liquid
assets. These results are fair given Aqua’s customer base growth since 1999. Besides the recession, which likely will hurt
collection activities, Aqua faces risk in regulatory lag. Regulatory lags may hamper a utility’s ability to raise cash through
operations on a timely basis, making administration of rate cases one of the most critical aspects of utility financial
management.8
On the other side of the balance sheet, Aqua America has reduced short-term debt by nearly 3% annually since
1999, shifting its debt load out on the curve to more closely match asset lives. (Long-term debt rose 11.7% and subsidies,
or “contributions in aid of construction”, rose 14.3% over the period.) Aqua’s working capital position, then, is rosier
prima facie but perhaps less so when one considers the strategic shift. By the same token, debt and leverage ratios have
remained stable, if not slightly sloped upwards since 2004. Increases in debt have not outpaced those of equity, and Aqua
has experienced low relative capital base variation. The latter two seem to be playing catch-up, as their times interest
earned have spiked and caught Aqua’s downward trend.
Unfortunately, Aqua America’s enviable fundamental positions have not translated into higher returns on
investment. In fact, ROE is trending downward. WTR currently returns less investment than do AWR and CWT; WTR,
though, began the millennium from a point of significant marginal advantage. In fact, Aqua’s net and operating margins
still outpace AWR’s and CWT’s by nearly 6% and 19%, respectively. Clearly, time has conspired to allow agile aspirants
to become more productive, while Aqua seems either to have entered a maturity stage, has been mismanaged, or has
grown too fast (affecting integration of new assets ). At the same time, Aqua America has increased its customer base by
5% annually since 2004 (adjusted for divestures).9 So, despite significant market power, Aqua America has struggled to
increase returns on capital and, as a result, equity investment. By nearly every functional element of ROE – ROC, net

profit margin, and capital turnover – Aqua fared worse in 2008 than it did in 2004. Only financial leverage rose, and
while that may have been at management’s behest, that factor alone proved not to be enough to prevent ROE from sinking
3.3% over the period. Categorical results are flatter over the 10-year period, during which ROE “only” fell 0.3%, but
signs point to a company at a crossroads. In the past, WTR has divested under- or non-performing assets, including water
systems, activity I expect to see in the coming periods as the firm prepares to refocus in this stimulus era.10
In the nearer term, just as systems integration bogs down capital returns, technical factors should weigh on share
price and prevent significant breakout. For months, analysts, commentators, and pundits alike have repeatedly touted
Aqua America as a “can’t miss” in this economy. Indeed, Aqua has outperformed major benchmarks over five-, three-,
and one-year periods, yet fundamentals tell a somewhat different story going forward. Technical indicators do, too. The
Relative Strength measurement (RSI) and Williams %R each tell a story – albeit differently – of an overbought stock.
RSI compares stock returns to benchmark returns, and WTR easily outran the S&P 500 from 2004-2009. I see signs of
fatigue, or mean regression. WTR stock actually had positive returns in October 2008, so a major (2x) swing over the last
quarter, on high volume, may confine WTR to the Yogism “That restaurant’s so popular, no one goes there anymore.”11
Williams %R gives explicit under/overbought signals to investors, generally over 14 days. The WTR stock price has
bounced a great deal lately, and as recently as early March was thought to be oversold. It has since moved into
overbought, bearish territory (> -20).12
Similarly, the Commodity Channel Index (CCI) tells investors when a stock has
moved significantly enough away from its 20-day, adjusted moving average. CCI only indicates directionality 20-30% of
the time, and currently it indicates that investors should, in fact, sell WTR (or to continue not to own it at all).13
MACD, standard SMA, and Fibonacci Extension functions proved helpful in assigning momentum and shape to
WTR’s chart. Since October, WTR looks to have taken on a head-and-shoulders shape, a leading indicator of reversion.
The MACD path suggests that a downward trend began to develop when WTR touched near the resistance level of $20 on
March 23rd
. The 50-day SMA passed the 200-day SMA in October, and while it remains above, the two look to be
converging. Consequently, MACD diverged from its relative gravity and indicates current downward momentum.
Finally, Fibonacci Extensions helps explain curve resistance, support, and shape. Fibonacci draws conclusions
from boundaries, expressed as percentage, derived from retracement levels between two “swing points.” Since reaching
the 100% line (near $20) late on March 23rd
, WTR has retraced back through the 76.4% line, bounced off of the 61.8%
line (a support level), advanced back to 76.4% but turned back and blew through the 61.8% resistance – a decidedly
negative trend. Going through a level is supposed to predict further surge or recession to the next Fibonacci level, at
which point investors should buy or sell.14
This will remain a stock of great interest as long as the government’s economic stimulus concentrates on
infrastructure. Integration will continue to be challenging but do not expect it to stop soon. Said CEO Nick Benedictis on
March 23rd
, when asked about the company’s direction: “Investing in the future of the country by improving infrastructure
and buying up all these small, undercapitalized water companies.” For his sake, Aqua America will hopefully have turned
around operations before investors will have ever noticed anything was amiss.

Figure 1. Since weekly and monthly data were so significantly different and nonsensical, frankly, those data were tossed. The R2 statistic
was the primary determinant of which beta to use: 1-, 3-, or 5-year regressions. The adjustment is the standard Bloomberg adjustment:
𝜷𝒂𝒅𝒋 = 𝟐

Then, I merely weighed the S&P 500 and S&P 400 Midcap indices at 50% and summed the beta factors.

Classical Technical Analyses
Figure 3 Even though the shorter (50-day) SMA moved above the
200-day SM A during WTR's October rally, the averages seem to
be re-converging - a fact amplified when looking at the MACD.
Figure 4 October's tremendous rally against the market has
created an aura of invincibility around WTR. That may be short-
lived; however, as business integration and technical trends
weigh heavily on the share price back down.
EXHIBIT K
Williams %R Explained
Definition: A technical analysis oscillator showing the current closing price in relation to the high and low of the past N
days (for a given N). It was developed by trader and author Larry Williams.
The oscillator is on a negative scale, from -100 (lowest) up to 0 (highest). A value of -100 is the close today at the lowest
low of the past N days, and 0 is a close today at the highest high of the past N days.
Williams used a 10 trading day period and considered values below -80 as oversold and above -20 as overbought. But
they were not to be traded directly, instead his rule to buy an oversold was
%R reaches -100%.
Five trading days pass since -100% was last reached
%R rises above -95% or -85%.
or conversely to sell an overbought condition
%R reaches 0%.
Five trading days pass since 0% was last reached
%R falls below -5% or -15%.
Equations
Assumptions: Generally run over a 7- to 14-day period.
Example
Figure 5. These Williams %R data were run on 3/24/2009 using WTR pricing data from Bloomberg.
3-day Williams %R
1-year Williams %R
Figure 6. The 1-year chart indicates recent movement above the -20 threshold; therefore, SELL
EXHIBIT L
Commodity Channel Index (CCI) Explained
Definition: The Commodity Channel Index is often used for detecting divergences from price trends as an
overbought/oversold indicator, and to draw patterns on it and trade according to those patterns. In this respect, it
is similar to Bollinger bands, but is presented as an indicator rather than as overbought/oversold levels.
The CCI typically oscillates above and below a zero line. Normal oscillations will occur within the range of
+100 and -100. Readings above +100 imply an overbought condition, while readings below -100 imply an
oversold condition. As with other overbought/oversold indicators, this means that there is a large probability
that the price will correct to more representative levels.
Methodology
1) Calculate Typical Price ("TP"):
2) Calculate TPMA, a 20-day simple moving average of TP.
3) Subtract TPMA from TP.
4) Apply the TP, TPSMA, the Mean Deviation & a Constant (0.015) to the following formula:
Example
Figure 7. An investor would want to be long WTR in the red areas (> +100), and short in the green (< -100) areas. The most recent data, at
the far right, appears to be in the green - a bearish sentiment.
EXHIBIT M
Fibonacci Extensions Explained
Definition: Fibonacci levels are a standard measure for support and resistance levels within the market. These levels are
calculated by analyzing the retracement levels between two swing points.
Mechanics
What happens when price exceeds the very swing points we use to calculate our Fibonacci levels?
At what point do we look to exit our position?
The key to these questions are Fibonacci extensions. Fibonacci extensions provide price targets that go beyond a 100%
retracement of a prior move. The levels for Fibonacci extensions are calculated by taking the standard Fibonacci levels
and adding them to 100%. Therefore, the standard Fibonacci extension levels are as follows: 138.2%, 150%, 161.8%,
231.8%, 261.8%, 361.8% and 423.6%.
The first step in drawing Fibonacci extension levels is to identify two clear swing points. These points should be in
relation to both your current timeframe and length of trend.
The last part of the Fibonacci extension equation, is what to do when the asset hits the respective target. The first
inclination is to immediately close your position at the next Fibonacci level. Traders will have to fight this urge and wait
to see how the stock reacts at these Fibonacci extensions. Remember, the stock has exceeded previous swing highs and
could very well start an impulsive move.
Example
Figure 8. Retracement through a level indicates a downward trend to the next Fibonacci level (50.0%); therefore, SELL on downtrend.
