Market Reactions to Quarterly Earnings Surprises: The Impact of Financial Statements’ Data Disclosed with Earnings
Abstract
This study focuses on market reactions to earnings and other financial statement information that is concurrently disclosed in preliminary earnings press releases. We use a large sample of heterogeneous companies and investigate whether market reactions to earnings surprises vary systematically with the amount of financial statement detail that is included in earnings press releases, after controlling for the timing of announcements and factors related to firms’ information environments. We observe a dramatic increase in the amount of detail disclosed concurrently with quarterly earnings in the years following Regulation Fair Disclosure. We find that level of financial statement detail is positively associated with the magnitude of the earnings surprise (and more so for negative surprises), firm size, volume of trade, likelihood of raising new capital and analysts' coverage. Conversely, it is negatively associated with the timing of press releases. Turning to the market-based analysis, we find that absolute abnormal returns are higher the more detail is disclosed in the preliminary earnings release, and that the level of detail is more strongly associated with unexpected returns when earnings surprises are extreme. We also find that market reactions to earnings surprises decline over time, but increase with the level of financial statement detail in preliminary earnings releases. However, the importance of detail to the interpretation of extreme earnings surprises has declined over time.
Market Reactions to Quarterly Earnings Surprises: The Impact of Financial Statements’ Data Disclosed with Earnings
1. Introduction
Since Ball and Brown (1968), Beaver (1968) and as reviewed by Lev (1989) and Kothari
(2001), numerous studies have consistently documented a positive and statistically significant
association between excess stock returns and unexpected earnings during the short windows
around preliminary earnings press releases.1 These findings imply that market participants
obtain, process, and react to new earnings information, setting security prices according to the
earnings news. Still, there has been some concern about the role of earnings news in explaining
the total variability of stock prices around preliminary earnings announcements (Lev, 1989), and
the potential deterioration over the years in the association between earnings news and short-
window returns around them (Collins et al., 1997; Francis and Schipper, 1999; Lev and Zarowin,
1999).
Preliminary earnings press releases often convey additional information beyond earnings,
including other financial statements’ data that may be value-relevant for market participants
(Chen et al., 2002). Because preliminary earnings press releases are not mandatory, companies
select the level of detail they wish to disclose concurrently with preliminary earnings. There
exists considerable variation in level of detail across preliminary earnings press releases. Some
of these voluntary additional data are in fact used by market participants to set prices,
incrementally to the effects of the earnings news. For example, Ertimur et al. (2003) provide
evidence that investors react and properly utilize revenue data that are contained in preliminary
1 Most studies used excess stock return and signed unexpected earnings as dependent and independent variables, respectively. Beaver (1968), on the other hand, was the first study to include absolute excess returns and volume of trade as dependent variables and absolute unexpected earnings as independent variables.

earnings announcements. Many companies now include detailed income statements, some
include condensed balance sheets (or balance sheet line items), and far fewer include any cash
flow line items in their earnings press releases2.
In a recent study, Francis et al. (2002) randomly selected 30 companies and examined
2,190 earnings press releases over the period 1980-1999. They provide evidence that the amount
of information in press releases (including additional financial statement data) has increased
significantly over time and show that the increased market reaction to earnings press releases
over time is associated with the increase in the amount of information in these disclosures. Lo
and Lys (2001) argue that the disclosure of concurrent information in earnings press releases
may explain the disparity between an increased information content of earnings announcements
and the decrease in the value-relevance of earnings per se; while the increase in concurrent
information causes stronger market reactions around the preliminary earnings press releases over
time. The reaction to the earnings signal alone in fact declines over time.
Until recently it was prohibitively costly to examine the effect of concurrent disclosures on
the market reactions to preliminary earnings press releases using large samples, because data
from press releases had to be manually collected, read and coded. This is why the results in
Francis et al. (2002) are obtained using a small sample of 30 companies randomly selected from
their sample of large and stable 426 companies with complete quarterly financial data over 20
years. In contrast, our study employs the preliminary earnings database available from
Compustat and Charter Oak through WRDS, together with the SEC filing dates supplied to us by
Compustat. These databases allow an investigation of earnings and concurrent information
2 At the time of this draft, IBM preliminary earnings releases contain income statement and balance sheet information, but not cash flow data. See, e.g., IBM’s 2007 Q1’s release on April 17, 2007 at: http://www.ibm.com/investor/1q07/1q07earnings.phtml

disclosed during preliminary press releases using a very large sample of heterogeneous
companies with substantially different information environments.
The purpose of our study is to examine (i) whether market reactions to earnings are
affected by other financial statements information concurrently disclosed in preliminary earnings
announcements; (ii) whether the trend of stronger market reactions to earnings information over
time is associated with the increasing level of other financial statement detail in preliminary
earnings announcements; and (iii) whether the information environment plays a role in the level
of detail provided in preliminary earnings releases, and if so, whether market reactions to
preliminary earnings announcements are affected by the level of other financial statement detail
in preliminary earnings announcements after controlling for the differential effects of the
information environment.
As we explore the association between earnings news, level of detail in preliminary
earnings announcements and market reactions, we also control for the timing of the earnings
press release relative to the quarter-end, a factor omitted by Francis et al. (2002), likely because
of their small sample. As Chambers and Penman (1984) and Kross and Schroeder (1984) show,
firms with good (unfavorable) earnings news tend to report earlier (later) than their expected
reporting dates, with market reactions that are in the same direction as the prompt (delayed)
reporting. As we show below, large companies tend to issue preliminary earnings
announcements earlier than small companies, and their announcements usually contain more
financial statement detail than those of small companies. Thus, with the large sample available to
us, we can adequately control for the timing of the earnings release as well as for cross sectional
differences in firms’ information environment and their effects on the association between detail
level and market reactions.

The contribution of this study to the literature is along several dimensions. First, it sheds
additional light on the voluntary activity of preliminary earnings announcements, and more
specifically on the level of financial statement detail firms choose to include along earnings in
these announcements. Second, it explains the cross-sectional variation in the amount of financial
statement detail concurrently disclosed with quarterly earnings. Third, it examines whether
market reactions to the preliminary earnings releases are sensitive to the level of detail for a large
sample of firms and for different sub-samples depending on the information environment of
firms. Fourth, it controls for the interaction between the timing of the preliminary earnings
announcements and the level of financial statement detail in measuring market reactions to the
announcements. Finally, it provides additional evidence about the role that financial statement
detail in preliminary earnings announcements plays in explaining the trend of increasing market
reactions to earnings announcements over time.
To facilitate the empirical testing, we design and implement three scoring mechanisms that
measure the amount of financial detail in earnings press releases. The first is based on a simple
tally of the items included in our analysis from the income statement, balance sheet and the
statement of cash flows. The second subjectively assigns weights to each financial statement
item based on the relative importance of the item as depicted by prior studies. The third is based
on “market” weights, which are obtained by regressing the market reaction to earnings on
earnings surprises and an indicator variable that represents whether the financial statement data
item was included in the preliminary earnings announcement. We show that the amount of
financial detail in press releases has increased dramatically following Regulation Fair Disclosure
in late 2000.
5
We find that the level of detail score is positively associated with positive earnings
surprises, but significantly more so with negative earnings surprises. This result suggests that the
likelihood of more disclosure is higher when earnings news is bad, consistent with the argument
that companies increase disclosure to reduce litigation costs.3 We also find that the level of
financial statement detail is positively associated with firm size, earnings volatility, volume of
trade, the likelihood of raising new capital and analysts' coverage, and negatively associated with
the timing of the press release.
Turning to the market-based analysis, we show that, consistent with Francis et al. (2002),
market reactions are stronger the more information is disclosed in preliminary earnings releases.
However, we also show that these additional financial statement details are used more strongly
by market participants when earnings are extreme, i.e., that the absolute unexpected earnings are
more strongly associated with absolute unexpected returns the larger the amount of financial
statement detail concurrently disclosed with earnings. This result generalizes that of Francis et al.
(2002), who apparently due to their small sample size did not investigate this interaction effects.
We also find that while the coefficient on absolute unexpected earnings in explaining absolute
unexpected returns declines over time, the coefficient on the association between detail score and
absolute unexpected returns actually increases over time, even after controlling for variables that
affected by the firm’s information environment. We also find that the coefficient that measures
the interaction between absolute unexpected earnings and level of detail and its association with
absolute abnormal returns has decreased over time. This result explains the disparity between the
decline in the value relevance of earnings and the increasing overall reaction to press releases, as
suggested by Lo and Lys (2001).
3 This argument is consistent with the findings in Skinner (1994) and Kasznik and Lev (1995).

Our study continues as follows: Section 2 discusses the research design. Sample selection
and data requirements are discussed in Section 3. The results of our analyses are provided in
section 4, and section 5 provides concluding remarks.
2. Research Design
2.1 Institutional Setting
The majority of companies voluntarily announce their operating results for the preceding
quarter before filing the required 10-Q or 10-K Form with the SEC. The median company
announces preliminary earnings about 27 days after quarter-end, as shown by Easton and
Zmijewski (1993). Most companies actually file their 10-Q or 10-K Form with the SEC on the
last day or two of the allowed period, as is shown by Griffin (2003). Since the preliminary
earnings release is a voluntary activity, each company can choose the level of financial statement
detail it wishes to disclose in the preliminary earnings release. About 95% of companies include
sales along with earnings (Jegadeesh and Livnat, 2006). About 40% of the companies in the
sample of Chen et al. (2002) provide balance sheet data that can be used to estimate current
accruals. As we show below (Table 2), fewer than 10% of our sample observations have line
items from the statement of cash flows.
When a company issues a preliminary earnings report, Compustat extracts as many line
items as it can from the preliminary earnings release and incorporates it in its quarterly database
with an update code of "2". After the company files its 10-Q (or 10-K) Form with the SEC,
Compustat extracts the line items again from the official filing and overwrites the preliminary
figures, denoting them with an update code of "3". The process of extracting data from the
preliminary earnings releases is quite fast, and is usually completed within 48 hours from the
7
press release. The process of extracting the information from the 10-Q and 10-K Forms is much
longer, and in some cases of smaller companies it can take more than a month or two after the
SEC filing for the final data to be included in the Compustat database.
The initial research design problem that we need to tackle is the identification of those
observations where a preliminary earnings release is issued prior to the SEC filing, as some
companies may issue an earnings press release together or after the SEC filing.4 Compustat
includes the preliminary earnings release date in its quarterly database, and I/B/E/S includes it
for firms covered by analysts. However, the preliminary earnings release date in Compustat may
actually be the SEC filing date subsequent to 1999. Until some time in year 2000, Compustat
used to insert a missing value code if a firm had not issued a preliminary earnings release.
Afterwards, Compustat revised its methodology and began including the SEC filing date for the
earnings report date. Furthermore, to ascertain what market participants obtained in the
preliminary earnings releases rather than the subsequent SEC filings, we require that the
preliminary earnings release date be at least three days prior to the SEC filing date. This requires
us to be able to identify the SEC filing dates for each firm; information that is typically
unavailable in Compustat. However, Compustat provided us with the SEC filing dates for 10-Q
and 10-K Forms for many firms in its database beginning in 1991. Thus, we are able to
determine which companies issued preliminary earnings announcements at least three days prior
to their SEC filings.
To identify the line items that were included in the preliminary earnings release, we use
another database provided to us by Charter Oak, which is also available for purchase through
Compustat in WRDS. Charter Oak has collected the weekly CD-ROMs that were sent to
4 See Stice (2001). After 2002, less than 0.1% of our sample companies issue press release subsequent to the SEC filing.
8
Compustat clients over the years, where some data are designated with an update code of "2" and
others with an update code of "3". Using the update codes of "2", Charter Oak is capable of
constructing a database that includes the preliminary line items reported by companies in their
preliminary earnings press releases. Thus, we can identify which financial statement line items
were included by each company in its preliminary earnings press release. This enables us to use a
very large sample in our study without the need to read and code actual earnings press releases,
as in Francis et al. (2002).
We should, however, point out two potential shortcomings of our research design. Because
the Charter Oak database includes only financial statement data, we limit our study to the effects
of financial statement line items rather than the other potentially useful non-financial and
forward-looking information contained in the preliminary earnings releases, as do Francis et al
(2002). On the other hand, coding such information in preliminary earnings releases may suffer
from subjective assignments and classifications of information.
The second shortcoming of our design relates to conference calls and the potential
disclosure of information to selected parties prior to the issuance of Regulation Fair disclosure in
October 2000 (REG FD). It is commonly assumed that prior to REG FD some companies
disclosed financial statement line items to a select group of analysts and investors in conference
calls and closed meetings. After REG FD, these items are broadcasted to all investors in the open
conference calls. Kohlbeck and Magilke (2002) argue that additional information provided by
conference calls combined with an increased conference call activity is the source of the increase
in information content of earnings. They find that after controlling for conference calls, the
information content of earnings has not increased during 1995-2000, and for small companies
9
has even decreased. This is consistent with additional information beyond earnings being
released in conference calls.
Kimbrough (2005) finds that the initiation of conference calls is associated with a
significant reduction in the serial correlation in analyst forecast errors and post-earnings
announcement drift. He also finds that the reduction in post-earnings announcement drift
surrounding conference call initiation is concentrated in companies with the most significant
drift, particularly small and least heavily traded companies, indicating the potential importance
of controlling for the firm’s information environment.
Bushee et al. (2004) examine the effect of REG FD on managers' decisions regarding the
timing and content of conference calls. Their results suggest that the new rule had a negative
impact on managers' decisions to continue hosting conference calls. Contrary to views expressed
by critics of REG FD, they do not find evidence that the new rule decreased the amount of
information disclosed during the call period. They also find that REG FD increased price
volatility for firms that previously restricted access to their conference calls relative to
companies that prior to the new rule held open conference calls, indicating that additional new
information beyond earnings is likely disclosed in the conference calls.
To the extent that limited-access conference calls and closed meetings are actually the
instrument that is used by investors to learn new value-relevant information that is unavailable in
the preliminary earnings announcements, and to the extent that conference calls are conducted
within the three-day window centered on the preliminary earnings release date, our study will be
biased against finding any effects of the additional disclosures in preliminary earnings releases
beyond earnings on market reactions to earnings surprises prior to 2001. This bias is unlikely to
exist subsequent to REG FD when all investors are supposed to obtain the same material
10
information simultaneously, so we include separate results for the periods prior and after REG
FD. Our study is the first to examine the effects of concurrent disclosures in preliminary press
releases before and after REG FD.
2.2 Detail Scoring Mechanism and its Determinants
To measure the amount of information in the preliminary press release we design and
implement three scoring mechanisms based on the number and relative importance of financial
elements included in each quarterly press release. Initially, we identify 10 income statement
items, 13 balance sheet items and 4 cash flow items to be included in the scoring mechanism.
Second, we assign weights based on three distinct methods – "Equal", "Subjective" and "Market"
Scoring. The Equal Scoring method is the simplest: the score is based on the number of items
included in the quarterly press release. The “Subjective” scoring method is based on assigning
subjective weights of "1", "2" or "3", where "3" denotes higher importance than "2", which, in
turn, is assumed to be more important than "1". We assign the weights based on prior studies.
For example, given the importance of revenues in prior studies (Ertimur et al., 2003) we assign a
weight of "3" to "Sales." We assign a weight of "2" to "Inventory", which can be used to estimate
current accruals, and a weight of "1" to "Depreciation Expense", which typically does not change
much from one quarter to another. Weights for the “Market” scoring methods are based on the
relative coefficients obtained by regressing absolute excess return around earnings
announcements on absolute unexpected earnings, control variables (described below) and an
indicator variable that is equal to "1" if the line item is available in the press release. We explain
and demonstrate the use of the three scoring methods in the Appendix. We report results based
on the Equal Scoring method and conduct sensitivity analysis using the other two methods.
11
The amount of detail in an earnings press release should depend on benefits accruing to the
company from supplying additional information (voluntarily), on disclosure costs, and on capital
market participants' demand for information. Companies may disclose more information in
preliminary earnings press releases to support and interpret good earnings news or to provide
mitigating explanations in cases of bad earnings news. As the propensity to disclose more
information may be different in good and bad news, we examine the association between the
detail score and positive and negative unexpected earnings. Similarly, companies with more
volatile earnings are more likely to increase the amount of detail in earnings press releases to
mitigate the effects of earnings variability on share prices.
Investors' demand for additional financial information may also drive companies to include
more detail in their quarterly earnings press releases. For example, it is expected that larger firms
will disclose additional detail due to their more complex structure of operations than smaller
companies, and also because shares of larger companies are likely to be held by professional
investors with higher demand for more timely financial information. Similarly, the demand for
additional financial information is likely to be higher for firms with larger trading volume, for
firms that seek to raise new capital and for firms that are followed by analysts as these
companies are more visible in the market. Also, more visible companies are more likely to
reduce the cost of capital through supplying more information in a timely manner (Botosan
1997).5
The company also faces direct costs of providing more detail in preliminary earnings
releases. These costs include more timely review of the press release by the company's auditor
before it is disclosed, the firm’s ability to produce other financial statement data with sufficient
5 Regarding trading volume and analysts' coverage, the arguments could be reversed: Companies have higher trading volume and are followed more closely by analysts because they provide more information. As these variables are not the focus of our study, we consider them as control variables in our study and ignore the direction of causality.
12
reliability before finalizing the data for SEC filings, and the potential that some items will have
to be revised by the SEC filing if errors are subsequently discovered (Hollie et al, 2005). A
reasonable proxy for disclosure costs is the timing of earnings announcement. Controlling for the
information itself, companies that release information relatively early are likely to have lower
direct disclosure costs. We therefore include a variable that captures the relative timing of
earnings announcements and expect that, ceteris paribus, early press releases include more
financial detail than late press releases.
We therefore estimate the following model to explain the level of detail score:
The dependent variable – ABSRETPit – is the absolute value of excess stock returns in the
three-day window centered on firm i's preliminary earnings announcement for quarter t, minus
14
the absolute value of excess returns in the three-day window around day -7, where day 0 is the
preliminary earnings announcement date. ABSUEit is the absolute value of quarterly earnings
changes between earnings in quarter t and earnings in quarter t-4, scaled by market value of
equity at quarter-end. All other variables are as defined for Equation (1).
3. Sample and Descriptive Statistics
The initial sample contains all companies covered by Compustat with a market value in
excess of $10 million at quarter-end, beginning with the fourth quarter of 1990 and ending in the
third quarter of 2005, or 514,435 firm/quarter observations. We then delete the following
observations: (i) net income before extraordinary items (item 8 on quarterly Compustat) is
missing, (ii) total assets is equal to zero, (iii) total sales for the quarter is below $1 million, and
(iv) foreign-incorporated firms. This yields 334,573 observations.
At this point, we rank all firm/quarters by the preliminary unexpected earnings (preliminary
earnings minus earnings four quarters before, scaled by market value of equity at quarter-end)
and match to CRSP using the WRDS CRSP-Compustat Merged file, leaving 323,107
observations. We delete all observations where the preliminary report date is not at least three
days prior to the SEC filing date, or where the preliminary announcement date is in excess of 120
days after quarter-end, which are either very late announcers or data entry errors, leaving us with
223,272 observations. For the remaining observations, we compute Buy-and-hold excess returns
around preliminary earnings announcements using CRSP and the Fama-French size and book-to-
market 6-group portfolios, ending in a sample with 216,029 observations. This becomes our
sample, although for some tests additional variables will cause elimination of observations with
missing data on these variables.
15
Excess returns are measured in the three-day period (-1,+1) centered on the release of
preliminary earnings (day 0) or day -7. Excess Buy-and-hold returns are calculated as the Buy-
and-hold return from CRSP minus the Buy-and-hold return on the equally-weighted portfolio of
firms with the same size (market value of equity) and book-to-market (B/M) ratio. Daily returns
and cut-off points on the size and B/M portfolios are obtained from Prof. Kenneth French’s data
library, based on classification of the population into six (two size and three B/M) portfolios.
Observations in the top and bottom 0.5% of excess return are deleted from the sample to ensure
that our results are not driven by outlying returns. Portfolio returns are computed each quarter.
Table 1 presents the number of firm/quarter observations per year, median firm size
(market value of equity), percentage of loss-reporting companies and median annual detail score.
Consistent with prior studies, the percentage of loss-reporting companies reached its highest
level in 2001 (34.1%) and decreased afterwards. Median detail score increased over the study
period, reaching 0.69 in 2005, with a dramatic shift in 2000.
(Table 1 about here)
Figure 1 presents mean and median detail score for each quarter during the sample period
(Q4 1990 – Q3 2005). The pattern of detail score has changed considerably during the sample
period. From 1990 to 1996, mean and median detail scores were stable (mean around 0.25 and
median around 0.15). From 1997 to 1999, mean and median scores vary significantly.6 Since
2000, we observe a monotonic increase in scores, primarily because of the disclosure of balance
sheet and cash flow information in press releases. This may be related to Regulation Fair
disclosure (REG FD) in October of 2000, which required firms to disclose material financial
6 Discussions with Compustat executives indicated that there were fewer employees to collect and enter data during the dot.com period, which may have resulted in a smaller number of preliminary line items that entered the Compustat database with the update code of “2”, although those items might in fact have been available in the preliminary earnings releases. Instead, Compustat may have entered the final data with an update code of “3” for these line items. In sensitivity analysis, we repeat the tests without the affected quarters.
16
information to all investors simultaneously. Thus, firms that had previously disclosed balance
sheet and cash flow information to analysts in closed conference calls may have begun including
these additional details in preliminary earnings press releases. Currently, detail scores are close
to 0.70.7
(Figure 1 about here)
Table 2 presents the percentage of companies that include each financial statement item in
their preliminary earnings press releases for selected years. The table demonstrates a significant
increase in reporting detail following REG FD, mostly with respect to balance sheet and cash
flow information. Sales and summary figures such as Income from Continuing Operations, Total
Assets and Total Liabilities have been traditionally the most frequently disclosed items. An
interesting pattern is observed for cash flow items. In 1991, about 6% of companies included
cash flow items in press releases. This percentage decreased during the 1990s (potentially due to
inclusion of many additional smaller firms in the Compustat database), but started to increase
following REG FD. In 2005, about 20% of companies included cash flow items in their press
releases.
(Table 2 about here)
In untabulated analysis, we examine whether firms choose the level of financial statement
disclosure and maintain it across adjacent quarters. Out of 183,374 observations (firm-quarters
where adjacent quarter’s data are available), our Score variable (measured between 0 and 1, with
a mean of 0.456 for this sub-sample) has changed by less than 0.01 in 106,391 cases, by less than
0.05 in 140,106 cases and by less than 0.10 in less than 157,663 cases. Thus, firms that choose a
7 We also observe a change in the skewness of the detail score. Prior to 2000, median score was below the mean suggesting that a small subset of observation exhibits high scores pulling the mean upwards. After 2000, median score is generally above the mean suggesting that a relatively small subset of companies exhibits low scores pulling the mean down. This phenomenon demonstrates a fundamental shift in disclosure policy and may be attributed to an external shock such as REG FD.
17
disclosure level tend to maintain it consistently, and seldom make changes in that chosen level of
disclosure.
4. Results
4.1 The Determinants of Detail Score
Table 3 presents median annual detail scores by size levels, timing of earnings
announcements and analysts' coverage. We form three size levels based on market value of
equity at quarter-end, where the group of 'small' and 'large' firms contains the lower and upper
quartiles, respectively, and the 'medium' group contains the middle two quartiles. We also assign
observations into three groups according to earnings announcement timing (25%, 50%, and 25%)
as explained above. Regarding analysts coverage, a firm/quarter observation is considered
covered by analysts if at least one analyst had an earnings forecast for that quarter.
The table shows that detail scores were higher for large firms than for medium firms
between 1990 and 1996. Since 2000, detail scores for medium and large firms are similar and
even slightly larger in some cases for medium size companies. Also, in all quarters, detail scores
for medium size companies are larger than those of small companies, although the difference in
scores decreases after 2001. For example, in 1990 the median score was 0.115 for small firms,
0.148 for medium size companies and 0.269 for large firms. In contrast, in 2005, small firms had
a median score of 0.731, below the score for medium size firms, 0.800, which, in turn, is almost
equal to that of large firms, 0.808.
The timing of earnings announcements (the number of days between quarter-end and the
preliminary earnings announcement date) is also associated with detail score. The table shows
that firms that announce early have a higher score than firms that disclose in the middle 50%,
18
which, in turn, have higher scores than 'late' firms. This behavior is consistent over the entire
sample period. Detail scores also vary significantly by analyst coverage. Companies that are
followed by analysts have higher detail scores than companies that are not followed by analysts.
The difference in scores is attributed in part to differences in firm size as small firms are more
likely not followed by analysts, and firms “neglected” by sophisticated investors may not find it
in their best interest to provide additional detail in preliminary earnings announcements due to
less investors’ pressure or the lower likelihood of accessing the capital markets.
(Table 3 about here)
Table 4 provides the results of estimating Equation (1). We estimate this equation
separately for each quarter and report average coefficients and standard errors similar to Fama
and MacBeth (1973). First, we estimate Equation (1) using the entire sample. The coefficient on
unexpected earnings is 0.293 (significant at the 0.01 level, t = 13.02) when unexpected earnings
are positive. This coefficient is 0.026 higher when unexpected earnings are negative and the
difference between the coefficients is significant at the 0.01 level (t = 12.35). This result is
consistent with the argument that the propensity to disclose more information in preliminary
earnings announcements is higher when the earnings news is negative than when it is positive.
Possible explanations for this behavior are the desire to reduce litigation costs by providing
additional explanatory information when earnings changes are negative, or the desire to provide
supplementary information that will help investors react less negatively to the earnings news.
The volatility of earnings over the last eight quarters is also positively associated with
detail score, as reflected by the positive coefficient on EARNVOL (0.007, t = 14.06, significant at
the 0.01 level). This result suggests that companies with more volatile earnings provide more
detailed earnings press releases, as this information is useful for investors in interpreting the
19
earnings changes.
As expected, the coefficient on LOGMKT (firm size) is positive and significant at the 0.01
level, suggesting that, on average, large companies provide more information in earnings press
releases than small companies, likely in response to higher demand for information by
professional investors that tend to be more concentrated in large companies. Furthermore,
companies with higher volume of trade disclose more information in their press releases, as
reflected by the positive and significant coefficient on VOLUME. However, in this case it is
difficult to say whether higher volume translates to more demand for information or that more
information induces higher trading volume.
Companies that are more likely to raise capital in the market have, on average, higher detail
score, as reflected by the positive coefficient on FINA (0.031, t = 8.99). This result supports the
argument that companies that need access to the capital markets respond to a higher demand for
financial information by providing more detailed earnings press releases, attempting to reduce
their cost of capital. Furthermore, as demand for financial information increases with analysts'
coverage, companies that are followed by analysts respond to this higher demand by providing
more detailed earnings press releases. This is reflected in the positive coefficient on ANALYST
(0.003, t = 10.38). Finally, the coefficient on TIMING is negative, as expected, and highly
significant suggesting that, ceteris paribus, early earnings announcements are more detailed than
late announcements due to lower direct disclosure costs.8
We also estimate Equation (1) for three size levels and three levels of timing. Specifically,
we report results for the lower size quartile (denoted as "small"), the middle two quartiles
8 This result may seem counter-intuitive because to have more financial statement detail available for the earnings announcement may require more time after quarter-end. However, as reported in Table 3, larger companies tend to both announce their preliminary earnings earlier than smaller companies, and also tend to have more details in their announcements.
20
("medium") and for the upper size quartile ("large"). Several points are worth noting:
(i) The intercept increases with size, consistent with the results reported in Table 3 that larger
companies provide more information in their earnings press releases.
(ii) The association between positive earnings changes and detail score is stronger in large
companies than in small companies. However, the tendency to disclose more information
when earnings changes are negative is stronger in small companies than in large
companies, although this phenomenon exists in all three size levels. A possible explanation
for this result is that the probability of negative earnings is lower for larger companies and
consequently the propensity to disclose more information when earnings are negative is
diminished.
(iii) The strength of the association between Detail score and earnings volatility decreases with
size. This is expected as earnings volatility decreases with firm size as well.
(iv) The association between analysts' coverage and detail score is strongest for small
companies. This is because the number of "neglected" companies is relatively large in
small companies.
(v) The coefficient on TIMINGit becomes more negative with firm size. This is primarily
because there is much less variation in earnings announcement timing of small companies,
as many of them announce earnings late.
To complete the analysis in Table 3, we estimate Equation (1) separately for three levels of
announcement timing. Consistent with our prior findings, late earnings announcements include
less detail than early announcements, as reflected by the lower intercept for the 'late' group
relative to the 'early' group. The association between earnings changes and detail score is
consistent across different levels of announcement timing. In particular, detail score is higher in
21
negative earnings changes than in positive earnings changes in all three timing levels, and the
difference in detail score between positive and negative earnings changes is significant at the
0.01 level in all cases. All other variables exhibit similar behavior and are not sensitive to
different timing levels.9
(Table 4 about here)
4.2 Detail Score and the Market Reactions to Earnings Announcements
Before we turn to analyzing the effect of detail score on absolute excess stock returns, we
estimate the earnings response coefficients using the following model:
RETPit =γ0t + γ1tUEit + ηit (3)
RETPit is excess Buy-and-hold stock return in the three days centered on the preliminary
earnings announcements of firm i in quarter t; and UEit is the change in quarterly earnings from
quarter t-4 to quarter t scaled by market value of equity at quarter-end. The model is estimated
cross-sectionally each quarter for 60 quarters. The regression coefficients as well as standard
errors are obtained using the Fama and MacBeth (1973) approach. The results, which are
reported in Table 5, are consistent with prior studies. The earnings response coefficient is
positive and statistically significant, 0.022 (t = 10.72), and the average quarterly R2 is very low
(0.003). We also estimate the model for the three size groups (small, medium and large
companies), and obtain results consistent with prior studies; the earnings response coefficients
decrease with size. Thus, we feel that our sample is not different from samples used in previous
9 We regressed each of the quarterly coefficients in Equation (1) on a time counter. The results (not tabulated) indicate that most coefficients are quite stable over time. An exception is the coefficient on unexpected earnings, which increases steadily and significantly over time, suggesting that firms increasingly tend to provide additional detail when earnings surprises are larger. We also repeated the analysis with Subjective and Market Scoring obtaining similar results.
22
market reactions studies so the influence of detail on the association between market reactions
and earnings surprises is not due to a unique sample peculiarities.
(Table 5 about here)
Table 6 presents the results of estimating Equation (2). We also present results for two
distinct time periods – Pre REG FD (40 quarters from Q4 1990 to Q3 2000) and Post REG FD
(20 quarters from Q4 2000 to Q3 2005).
Consider first the results for all quarters. The coefficient on absolute unexpected earnings
(ABSUEit) is positive, as expected from prior studies, and significant at the 0.05 level (0.004, t =
2.17) for the entire sample period. This coefficient is larger in the Post REG FD period than in
the Pre REG FD period, where the latter is insignificantly different from zero. The coefficient on
SCOREit is positive and significant (0.003, t = 3.63), in line with Francis et al (2000), suggesting
that absolute excess stock returns around preliminary earnings announcements increase with the
amount of financial statement information disclosed concurrently with earnings. Moreover, the
coefficient on the interaction variable between detail score and absolute unexpected earnings
(ABSUEit x SCOREit) is also positive and significant at the 0.01 level (0.030, t = 4.48),
suggesting that additional financial statement detail is used more strongly by investors when
earnings surprises are extreme.
The coefficient on the detail score is significant and larger in the Post REG FD period than
in the Pre REG FD period, where the latter is insignificantly different from zero. In contrast, the
interaction between score and absolute unexpected earnings is significantly different from zero
for the Pre REG FD period, but insignificantly different from zero in the Post REG FD period.
These results are new to the literature and provide further contribution beyond Francis et al.
(2002), using a much larger and heterogeneous sample and controlling for the information and
23
regulatory environment of companies as well as the timing of the preliminary earnings
announcements.
Turning to the control variables in the model, the coefficient on TIMING is insignificantly
different from zero, once we control for other dimensions such as size and analyst following. As
expected, the coefficient on firm size (LOGMKTit) is negative (-0.003, t = -15.33) suggesting that
absolute excess returns around earnings announcements decrease with firm size, likely because
larger firms have more informative environments, so earnings affect prices less strongly. Also,
the positive coefficient on earnings volatility (0.001, t = 9.09) suggests that firms with more
volatile earnings are likely to have stronger market reactions when their earnings are announced.
Similarly, the coefficient on VOLUMEit is positive, as expected (0.010, t = 10.88), suggesting
that firms with higher share turnover are likely to also have stronger market reactions around
earnings announcements, likely because they are followed more closely by market participants.
Finally, the coefficients on FINAit and ANALYSTit are both positive, although the first is
insignificantly different from zero, suggesting that companies that are more likely to raise new
capital and companies that are followed by analysts are paid greater attention by market
participants when their earnings are announced, hence their larger absolute excess returns around
earnings press releases. These coefficients are not materially different before and after REG FD.
(Table 6 about here)
Since the timing of the preliminary earnings announcement is correlated with the level of
detail in the press announcements and firms’ size, we estimate Equation (2) separately for three
timing groups (early, middle, and late) and three size levels (small, medium, and large). The
results are reported in Table 7. Referring to the timing groups, the regression intercepts increase
with timing suggesting that excess stock returns are more volatile as earnings are released
24
relatively late, although this may also be related to the smaller size of late firms. Also, the
coefficients on absolute unexpected earnings (ABSUEit) are positive, but significant at the 0.05
level or better just for the early group. The coefficient on SCOREit is significantly different from
zero only for the early and middle group. Lastly, the coefficient on the interaction variable
ABSUEit x SCOREit is significant only for the 'middle' group – the 50% of the observations that
are neither early nor late. These results suggest that detail score provides more explanatory
power for extreme earnings when the timing of the press release is not extreme. In early or late
announcements, the timing of information release likely reveals additional information to the
market as well as information transfer between companies in the same industry, reducing the
explanatory power of SCOREit.
Turning to the size levels, several results are worth noting:
(i) The regression intercepts indicate that earnings news are more informative for smaller
companies with weaker information environments. Also, the coefficient on absolute
unexpected earnings is larger for small companies than for large companies, indicating the
larger role earnings news play for smaller firms.
(ii) The coefficient on SCOREit is significant only for medium size companies, suggesting that
the richer information environment of larger firms makes the additional level of detail in
the preliminary earnings announcement less relevant for investors, who may have obtained
that information from other sources.
(iii) The coefficient on ABSUEit x SCOREit is significant only for small companies. This result
suggests that absolute stock returns depend much less on the release of concurrent
information with earnings for large firms with richer information environments.
25
Overall, the results in Table 7 suggest that both timing of press releases and firm size are
major factors in explaining the association between absolute unexpected earnings and absolute
excess stock returns. The Table identifies sub-samples in which the detail score is a significant
contributor to the explanatory power of the association between earnings news and absolute
excess returns incrementally to timing and size. In particular, detail score is incrementally
significant in companies that are neither late in releasing preliminary earnings nor large. Recall
that large companies typically announce early and for those that provide more detail in their
preliminary announcements we expect a stronger market reaction. Small companies that report
late should have weaker market reactions.
(Table 7 about here)
As Francis et al. (2002) and Lo and Lys (2001) point out, there have been significant
changes over time in the association between absolute excess returns and absolute unexpected
earnings. These findings motivate us to examine the time series behavior of the coefficients
obtained from Equation (2). We estimate the following models using the 60 coefficients from the
quarterly cross-sectional regressions:
β1t = δ0 + δ1COUNTERt +λt (4a)
β2t = δ0 + δ1COUNTERt +λt (4b)
β3t = δ0 + δ1COUNTERt +λt (4c)
The dependent variables in Equation (4) are the regression coefficients obtained from Equation
(2) and COUNTER is a time variable from 1 (the first quarter in our data, Q4 1990) to 60 (the
26
last quarter of our data, Q3 2005). Recall that the cross-sectional regressions control for the other
variables (earnings volatility, analyst following, etc.
The results, which are reported in Table 8, show that the association between absolute
excess returns and absolute unexpected earnings has changed significantly over time, and also
that this association has changed significantly over time according to the level of financial
statement detail disclosed in the preliminary earnings announcements. Specifically, the
coefficient on unexpected earnings, ABSUE, has decreased during the sample period (-0.006, t =
-2.85) suggesting that the contribution of absolute unexpected earnings alone to the explanation
of absolute returns has deteriorated over time. In contrast, the role of information provided
concurrently with earnings has increased over time, as reflected by the increase in the coefficient
on SCORE (0.005, t = 2.81). However, the interaction between concurrent information and
earnings news has also decreased over time (-0.028, t = -2.21), suggesting that the additional
effects of financial statement detail on stock returns is for extreme earnings is decreasing over
time. Overall, the results in Table 8 highlight the increasing importance of concurrent
information in press releases over time and its effects on market reactions. These results also
support the argument in Lo and Lys (2001) that the value relevance of earnings has decreased
over time, but that the quantity and relevance of concurrent information in preliminary earnings
announcements have increased over time.
(Table 8 about here)
Our final analysis, provided in Table 9, focuses on matched samples rather than on linear
regressions. We identify companies with detail score in the upper quartile of the distribution and
match them with similar companies whose detail scores are in the bottom quartile during the
27
same quarter. We then compute average excess returns and average absolute excess returns
around the preliminary earnings announcements for the high and low detail samples.
In the first matching, we identify companies with high detail score and companies with low
detail score that are similar in size (where the absolute size difference is capped at 10% of the
high detail score company). The average excess return is larger for companies with high detail
score than for companies with low detail score (at the 0.05 level). Furthermore, the average
absolute excess returns are larger for companies with high detail score by 0.88% (t = 22.69). This
result is consistent with our prior analysis and with Francis et al. (2002). The second match is
performed by firm size and the decile of unexpected earnings. The difference in average excess
returns is close to zero, but the difference in average absolute excess returns increases to 1.12%
(t = 29.14). The third matching adds the number of analysts as another factor while the fourth
matching takes into account all of the above and the timing of press releases. The results remain
consistent – no difference in average excess returns but significant differences in absolute excess
returns. The results in Table 9 clearly show that increasing the amount of financial statement
detail disclosed concurrently with earnings is associated with stronger market reactions around
the earnings press release dates.
(Table 9 about here)
4.3 Sensitivity Analysis
All our analyses are performed using the subjective and market weighting to determine the
detail score. The results are insensitive to the alternative scoring method.
We estimated Equation (2) separately for negative and positive unexpected earnings. The
results about the effects of detail on the association between absolute excess returns and absolute
28
unexpected earnings are stronger for negative unexpected earnings changes than for positive
ones, indicating that market participants incorporate more of the non-earnings information when
earnings decline.
To assess the effect of survivorship on our analysis and to facilitate better comparison with
the results obtained by Francis et al. (2002), we estimated Equation (2) using companies with at
least 55 quarters of data. We find that the coefficients on detail score (SCOREit) and the
interaction between detail score and absolute unexpected earnings (ABSUEit x SCOREit) are
larger and statistically more significant than those reported in Table 6.
We repeated the market reaction tests with an additional dummy variable indicating
whether the firm reported a loss during the quarter or not. The results on the detail score
coefficients were qualitatively the same. We also repeated the analysis without the first two
quarters of 1999, when Compustat may have been unable to record all the preliminary
information in a timely manner due to staff shortages. The market reactions results are a bit
stronger than those reported in Table 6 with respect to the effects of the detail score, and we
obtain the same conclusions as those in Table 8 about the evolution of the coefficients on
earnings, detail score and the interaction between the two over time.
5. Summary and Conclusions
This study investigates the effects of additional financial statement disclosure in
preliminary earnings announcements on the association between absolute unexpected earnings
and absolute excess returns in the three-day window centered on the preliminary earnings
announcements. It shows that market reactions to unexpected earnings increases with the amount
29
of financial statement detail concurrently disclosed with earnings, after controlling for variables
that affect the firm's information environment.
The study is based on a very large sample of firms and uses a unique database to study the
effects of additional financial statement disclosure in preliminary earnings announcements. This
extensive sample allows us to investigate the determinants of the level of detail in preliminary
earnings announcements, their evolution over time, and control for the effects of the information
environment on the relationship between earnings surprises, excess returns and the level of
additional financial statement detail in preliminary earnings announcements.
We find that the level of financial statement detail in preliminary earnings releases has
increased over time and in particular after the enactment of Regulation Fair Disclosure in 2000.
Typically, there is a positive relationship between the level of additional financial statement
detail in preliminary announcements and size, investors’ interest in the company, the company’s
earning volatility and firms’ likelihood to access the capital markets. There is an inverse
relationship between the announcement timing and the level of detail in the announcement;
larger firms tend to announce early and to have more financial statement detail in their
preliminary earnings announcements than smaller firms.
We also find that the association between market reactions and unexpected earnings is
affected positively and significantly by the level of additional financial statement detail in
preliminary earnings announcements. These effects are stronger for smaller firms and for firms
that announce early. Extending Francis et al. (2000), we find significant explanation for the
interaction between the level of financial statement detail and earnings surprises as it relates to
market reactions; this indicates that more extreme earnings surprises which are accompanied by
greater detail tend to be more strongly associated with greater market reactions. This implies that
30
investors likely seek and utilize other than earnings information when earnings surprises are
extreme, probably attempting to better assess the persistence of the earnings surprises.
The results of this study have implications for academics, managers and investors. They
highlight the determinants and effects of additional (to earnings) voluntary disclosures, and how
they are utilized by market participants. The results can be used by management to assess the
likely effects of a decision to increase or decrease the level of additional financial statement
detail in preliminary earnings announcements. Finally, investors should pay close attention to
firms that decide to increase or decrease the level of financial statement detail in their
preliminary earnings announcements. Such decisions are likely driven by the firms’ intention to
attract more active and sophisticated investors in cases of increasing the level of detail, or to “fly
under the radar screen” in cases of decreasing the level of detail. These actions have implications
beyond the additional information that is provided or withheld.

Notes: 1. Equation (2) is estimated separately for 60 quarters and regression coefficients and standard
errors are obtained using the Fama and MacBeth (1973) approach. The Table presents mean
44
coefficients and corresponding t-statistics. The dependent variable is absolute excess stock returns around preliminary earnings press releases minus the absolute excess return seven days prior to the preliminary earnings release date. Estimation is done separately for three timing groups and three size levels. The model is:
2. Timing Groups - Initially, we measure the number of days between quarter-end and the
preliminary earnings announcement date. We assign each observation into one of three Timing groups according to lag from quarter-end: lowest 25% into early group, middle 50% into the middle group and largest 25% into the late group. We conduct this analysis separately for quarters 1-3 and quarter 4.
3. Size levels - Size is measured as market value of equity. Small and large portfolios contain
the lower and upper quartiles of the sample, respectively, and the medium size portfolio contains the middle two quartiles.
4. See Table 6 for variable definitions. 5. Coefficients and standard errors in bold faces are significant at the 0.05 level (2-tailed test).

The Table presents excess stock returns and absolute value of excess stock returns for a sample of companies with high detail
score (score in the upper quartile) and a matched sample of companies with low detail score (score in the lower quartile). The table also presents the differences in excess returns and absolute value of excess returns and their significance levels.
2. Matching techniques: (i) Matching by Size (size difference is capped at 10%); (ii) Matching by Size and Earnings Surprise decile; (iii) Matching by Size, Earnings Surprise decile and the number of analysts following the firm, (iv) matching by Size, Earnings Surprise decile, number of analysts following the firm and the announcement timing (early, medium, late).
3. Excess returns are measured in the 3-day period (-1,+1) around the release of preliminary earnings. Excess Buy-and-hold returns are calculated as the Buy-and-hold return from CRSP minus the Buy-and-hold return on the portfolio of firms with the same size (market value of equity) and book-to-market (B/M) ratio. Daily returns and cut-off points on the size and B/M portfolios are obtained from Prof. Kenneth French’s data library, based on classification of the population into six (two size and three B/M) portfolios. Observations in the top and bottom 0.5% of excess return are deleted from the sample to ensure that our results are not driven by outlying returns. Portfolio returns are computed each quarter. The table presents average quarterly returns and t-statistics based on a Fama and MacBeth (1973) approach.

Appendix Scoring Methods
To measure disclosure detail, we initially identify 10 income statement items, 13 balance
sheet items and 4 cash flow items that form the basis for our scoring mechanism. We then assign
weights to each item based on the following methods - Equal Scoring, Subjective Scoring and
Market Scoring. For Equal Scoring, we assign equal weights of "1" to each item found on the
quarterly press release, but only if the item also appears in the subsequent SEC filing. If the item
does not appear in the subsequent SEC filing, we do not assign the item any weight, and ignore it
in our scoring. Under Subjective Scoring, we assign each item a relative weight of “1”, “2”, or
“3”, where a weight of “3” indicates high relative importance. For example, the item “Sales” is
assigned a weight of “3” whereas the item “Income Tax Expense” is assigned a weight of “1”.
Another example relates to the balance sheet: The items “Current Assets” and “Current
Liabilities” are assigned weights of “3” because they facilitate the estimation of operating cash
flows, while the items “Accounts Payable” and “Account Receivable” are assigned a weight of
“2” because they facilitate estimation of operating cash flows with greater accuracy and facilitate
estimation of current accruals. Under the Market Scoring mechanism we initially estimate the
Where ITEMjit is an indicator variable that obtains the value of "1" if item j (27 items)
appears in company i's press release for quarter t, and "0" otherwise. All the other variables are
48
as defined above. We obtain average coefficients and corresponding standard errors using the
Fama and MacBeth, 1973 approach for 60 quarters.
We compute market weights for each item as:∑
jj
j
ββ
. Table A1 lists the financial elements
and weights for each scoring mechanism.
(Table A1 about here)
To obtain a score for each quarterly observation, we initially examine the 10-Q filing of the
company in order to determine the maximum score possible. For instance, the item “inventory”
is included in computing the maximum score only if the item was separately disclosed in the 10-
Q filing. So technically, it is possible for each firm/quarter to have a different maximum score.
Only then, we compute the actual score for the preliminary press release and divide it by the
maximum score. We demonstrate the scoring mechanisms for the quarterly press release of AAR
Corp. The actual score is 0.500, 0.509 and 0.770 using the Equal, Subjective and Market scoring
mechanisms, respectively.

An example of an application of the scoring mechanism to a press release AAR REPORTS FISCAL YEAR 2006 FIRST QUARTER RESULTS • 22% sales growth; 109% income growth • 25% commercial sales growth; 16% defense services sales growth • 45% growth in Asia sales WOOD DALE, ILLINOIS (September 21, 2005) — AAR (NYSE: AIR) today reported net sales from continuing operations of $199.6 million for the first quarter of fiscal 2006, an increase of 22% compared to the prior year. Income from continuing operations more than doubled to $5.3 million or $0.15 per diluted share, from $2.5 million or $0.08 per diluted share in the year ago period, which included a $1.0 million pre-tax gain on extinguishment of debt. The sales and earnings growth for the quarter were driven by increased sales in the Aviation Supply Chain, Maintenance, Repair & Overhaul and Structures & Systems segments. Within the Aviation Supply Chain segment, sales increased 25% reflecting strong demand from our commercial and defense customers as AAR creates and provides cost-effective solutions for managing their supply chains. MRO segment sales increased 78% reflecting the commencement of operations at the Indianapolis Maintenance Center as well as increased sales at the Oklahoma maintenance facility. Structures and Systems sales increased 14% as the Company experienced stronger volumes across all businesses within this segment. Sales in the Aircraft Sales and Leasing segment were lower primarily due to joint venture accounting treatment, which excludes joint venture revenues from consolidated net sales. “This is a great start to fiscal 2006,” said David P. Storch, President and CEO of AAR. “We are seeing the benefits of the actions we have taken over the past few years to strengthen and grow the Company. Increasingly, our airline and defense customers are turning to AAR to meet their maintenance and engineering, supply chain and deployment needs.” Higher sales and operational efficiencies drove an improvement in gross profit margin from 16.2% to 17.4% year over year. Although selling, general and administrative costs increased as the Company made investments and prepared for growth, they declined as a total percentage of sales from 12.2% to 12.0%. Net interest expense was $0.5 million lower for the quarter due to lower average borrowings. The Company also made progress in its goal to improve asset performance, increasing working capital turnover from 3.0x to 3.6x. Investments in inventory primarily to support supply chain programs resulted in an operating cash outflow of $22 million for the quarter. We expect the returns from these investments to favorably impact results in future periods. Subsequent to the Company’s quarter-end, two valued customers, Delta Air Lines and Northwest Airlines, filed for bankruptcy. AAR was proactive in minimizing its exposure to these events, and the financial impact was minimal and was provided for in the first quarter. The Company continues to support both airlines by providing cost-effective solutions for their maintenance and supply requirements. Storch added, “We made progress on many fronts. Our results were significantly stronger than last year, and we won several new programs during the quarter, including the Airbus A400M cargo system program, a contract to provide pallets to the U.S. Air Force and the United Kingdom’s Royal Air Force E-3D AWACS and MESA Air Group supply chain programs, all of which should have a positive impact on future periods.” Storch continued, “We are also very pleased with the progress made at our recently-opened Indianapolis Maintenance Center, as the business unit produced profitable results in the quarter.” AAR is a leading provider of diverse products and value-added services to the worldwide aviation/aerospace industry. Headquartered in Wood Dale, Illinois, with locations around the world, AAR serves commercial and government aircraft fleet operators and independent service customers by providing Aviation Supply Chain services; Maintenance; Repair and Overhaul services; Structures and Systems manufacturing and Aircraft Sales and Leasing.
