New Directions in Traffic Measurement and Accounting

Wednesday, March 24th, 2010

Cristian Estan

The Problem

* Measurement and monitoring of network traffic required for Internet backbones.
* Useful for short-term monitoring (e.g., attacks), traffic engineering (e.g., rerouting), and accounting (e.g., usage based pricing)
* How can we do so without “tracking millions of ants to track a few elephants”?

State of the art – Cisco

* Sample packets at high speeds;
* Per flow information based on samples;
* Aggregate (based on ASes, prefixes, ports) at the router;
* Problems: inaccurate (due to and loss), memory-intensive, slow (needs DRAM).

Towards a NetFlow Alternative

* Small Percentage of flows (elephants) account for large percentage of traffic.
* Top 9% of flows account for 90% of AS pair traffic in backbones (Fang-Peterson).
* Can we directly track flows that send say over 1% of link bandwidth without keeping track of all flows?

How to identify large flows?

* Sample-Counting: uses sampling only to decide which flows to watch exhaustively.
* Multistage filter: uses multiple hash tables allowing large flows to be identified while only allowing a small number of small flows (false positives) to pass through filter.

UNCTAD/ISAR PROJECT ON ACCOUNTING BY SMES

Monday, March 22nd, 2010

Tatiana Krylova,

Head

and Enterprise Competitiveness Branch, UNCTAD

UNCTAD

* Conference on Trade and Development
* Established in 1964 as United Nations permanent intergovernmental body that deals with trade, investment and development issues
* ISAR is its main forum to address issues on harmonization of accounting standards

30 Years of International Accounting and Reporting at the United Nations

* Established in 1983 by the UN Economic and Social Council (ECOSOC)
* Intergovernmental body that serves as a global open forum to address issues of accounting harmonization
* Has 34 members, held 21 annual session attended by close to 200 delegates and experts from around the world representing regulators, standard-setters, professional and associations, academics, investment community, private sector and civil society
* Has a mandate to assist developing countries and economies in transition in implementing best international practices in a harmonized way

ISAR’s CURRENT PROJECTS

* Accounting education
* Environmental accounting
* Disclosures on corporate governance
* Accounting by the SMEs
* Disclosures on corporate responsibility
* Coordination of Russian translation of the IFRS

MAIN OUTPUTS

* Model accounting curriculum, used in about 20 countries
* Guidance on Environmental costs and liabilities, Manual on Eco-efficiency indicators
* Guidance on Disclosure on Corporate Governance
* Guidance on Accounting by the SMEs (Level II and Level III)

Background – Accounting by SMEs

* ISAR first deliberated on the accounting and financial reporting needs of small and medium-sized enterprises (SMEs) at its seventeenth session that took place in Geneva in July 2000
* In its deliberations, the Group of Experts noted that International Accounting Standards (IAS) were becoming more burdensome for SMEs to implement
* The Group recognized the need for a simple, understandable and user-friendly accounting and reporting system for SMEs.

Accounting by SMEs – the deliberation process

* After the seventeenth session of ISAR, a Consultative Group consisting of 23 experts from a wide cross-section of Member States was formed to formulate recommendations on the issue

* The Consultative Group conducted its consultations during ad hoc meetings held in Geneva and through electronic mail

Horizontal accounting within organizations

Sunday, March 21st, 2010

Robert Chenhall, Monash University

Approach

* Meaning of horizontal accounting (HA):
o What does HA look like: practices
o How does HA work: processes
* Theoretical perspectives that provide opportunities:
o A perspective (ABC)
o A strategic perspective (SCM)
o An organizational structural perspective
o An operations perspective
o A human resource management perspective

(Not consider relevant areas related to economics, marketing, IT, psychology and sociology)

* Conclusions

What is horizontal accounting within organizations?

* Accounting that assists in managing the efficiency and effectiveness of the value chain that exists within the .

Management Accounting (horizontal & vertical)

Horizontal accounting (entire value chain)

Horizontal accounting within the organization

Top management

Suppliers

Productive processes

Customers

* What does horizontal accounting look like?
o Practices: any management accounting practice that assists in managing the lateral dimension of the value chain
+ Strategic control: modelling that shows how facets of the value chain interconnect to provide opportunities for strategic advantage.
# integrated MCS: e.g. balanced scorecards, target costing, financial planning, ABCM.
+ Operational control: practices that direct operations and provide timely feedback for immediate correction and information for improvements.
# horizontal budgeting
# lean accounting
# integrated cost management
# non-financial measures (e.g. quality, reliability, throughput time, manufacturing measures, productivity measures (input/output)
# summary costs
# factory displays & charts

+ Personnel control: practices to evaluate the performance of individuals at levels of divisions, teams, individual employees and which may form part of reward & compensation
# Divisions:
* financials and type systems
# Teams:
* team maturity indexes, organizational climate surveys, team output measures
# Shop floor individuals
* non-financials
* qualitative & subjective measures
* 360 degree evaluations

o Processes (use): the way in which practices are used to assist in managing the lateral dimension of the value chain
+ Diagnostic use: used mainly for operational control
# Operational controls (action plans nested within strategy)
# Signalling and communicating strategy down to the value chain
# Providing boundary spanning information & help develop networks across the value chain
# Provide rhetoric and language for value chain management

+ Interactive use: used mainly for operational improvements & strategic control
# Identify problems & opportunities within the value chain
# Identify emerging issues that can address uncertainties and generate innovation related to the value chain
# Acquire information for personnel control

+ Use management accounting practices in conjunction with other controls (combinations or packages of controls)
# Combine formal practices with informal control, personal, clan, self control, professional control
* diagnostic and interactive
* formal controls and organic processes
* coercive and enabling

Theoretical perspectives that provide research opportunities

* A value chain perspective
o The internal value chain has long been recognized as:
+ processes that involve the means to convert inputs into outputs
# virtual organizations may manage the process without physical involvement in the transformation processes.
+ provides the basis to develop competitive advantage
o Activity-based costing was a response to managing the ‘value chain’

* ABC, ABCM research opportunities
o Surveys keep track of adoption and use
+ limited (& declining) interest in ABCM in the academic literature (both practice studies and theory-based research)
+ need an interesting angle if studying ABCM
# use as an example of:
* how MCS are diffused
* how do MCS assist/hinder change
* how MCS influence managers’ judgement
* how MCS relate to broader management initiatives related to strategy, work place improvements, innovation

o The ABC implementation literature
+ Large number of studies that have looked at technical and organizational/behavioral factors that influence effective implementation.
# Interesting broad findings
# Need for more insightful studies of processes and how they work through time.
# Useful research findings to transfer to studying implementation of other MCS
* e.g. performance measurement, budgetary systems
# Need to study effects of ABC together with other changes taking place within the organization
* how to disentangle effects of ABC from other change initiatives?

* A Strategy Perspective
o Strategic Cost Management (SCM) developed to move management accounting to a strategic approach
+ Consider the whole business strategically & how internal processes relate to strategy
o ABCM or SCM?
+ ABCM is part of SCM
# Other parts: e.g. value chain analysis, competitor costing, target costing, total cost of ownership, cost of quality, life cycle costing
o Research orientation used to study SCM
+ Many practice-based studies and prescriptions
+ Few theory-based empirical studies to identify what SCM is and how it works
# Mainly consider parts of SCM (e.g. ABCM, competitor costing, life cycles)

* Is SCM still an interesting area?
o NO: see John Shank’s chapter in Bhimani (2006).
+ Why has SCM lost its impact? Did it ever have an impact?
o Early enthusiasm in the 1980-1990s
+ Simmonds (1981): early links to strategy which was emerging as a way to link management disciplines
+ Kaplan & Johnson (1987) & Johnson (1992): showed the difficulties of MA & the need for a business related approach
+ Shank (1989): saw SCM as the way of the future
+ Cooper & Kaplan (1988); Shank & Govindarjan (1993) popularized ABCM as part of SCM
+ Bromwich and Bhimani (1994): was management accounting really irrelevant?
# Authors sympathetic to SCM, SCM did not take off like ABC.

* Clarifying ideas in the mid-1990
o Did the construct & theorizing of SCM ever get developed ?
+ Atttempts to consolidate and define SCM
# Considerable variation on its meaning, benefits and outcomes (Lord, 1996; Tomkins & Carr, 1996; Roslender & Hart, 2001, Anderson, 2006)
# Little carefully constructed research to refine construct of SCM and examine why it might have worked, and if not, why not?
+ SCM is a practice-defined construct
# The SCM construct is elusive and has evolved through time
* It is a generic approach with a marketing, strategy focus
* SCM can be applied to managing various functions (e.g. suppliers, customers, cost management, risk management) (see Anderson, 2006)

o Is SCM still relevant? Research opportunities
+ The essence of SCM is done by others
# Other disciplines are defining themselves ‘strategically’
* operations management, IT, HRM, strategists

. we need to understand these approaches

+ A strategic approach is more sophisticated than that used in most SCM research
# Does the rational approach to strategy as considered under SCM lack relevance?
* strategic problems cannot be objectively defined, they are open to interpretation from many different angles
* strategic problems are wicked problems

(interconnected, complicated, uncertain, ambiguous, conflicting)

# Strategy involves intended rationality but may involve high levels of subjectivity and complex behavioural responses
* take an approach that examine both the content of rational approaches and processes of behavioural responses

o Strategy as process as well as the prescriptive content (see Chenhall’s chapter in Chapman [2005]).
+ A process view starts to look at the dynamics of how SCM works (rational & behavioral) & implications for the value chain
# link MCS to the dynamics of these processes
* what are the dynamic relationships between strategic position, resources, value chain and outcomes?
* how is, and how should, strategy be formulated & implemented?
* who is involved in the strategy process and how do individual differences have effects?

* Some ways of studying aspects of strategy that have implications for the internal value chain & horizontal accounting
o The content of strategy
+ Conceptualizing strategy
# Conceptualize more specifically than archetypes (e.g. defenders-prospectors, build-harvest, cost-differentiation)
# Specific strategic priorities (e.g. quality, service, reliability, etc)
* shows clearer links to value chain
+ Hard and soft aspects of strategy as content
# Hard = relatively concrete, comprehensible, tangible
# Soft = relatively indefinite, elusive, intangible

o Hard aspects of strategic content
# Resource based view (competencies, capabilities, innovation capabilities) (Barney, 1991)
# Digitization: internet-enabled commerce relationship, digitalising business relationships (Bhimani, 2003; Sanchez et al 2006)
# Governance & enterprise risk management: examining governance and risk within the internal value chain (Collier et al, 2007)
# Globalization: convergence or diversity

(Drori et al, 2006)

o Soft aspects of strategic content
# Tangibles and intangibles (good progress in MCS research)
# Intellectual capital, knowledge-based organizations (good progress in MCS research)
# Exploration (pursuit of new knowledge) & exploitation (past knowledge).
* Consider together or do they follow each other ? (Gupta, Smith.& Shalley, 2006)
# Innovation/creativity and their linkages
* Some MCS research on innovation
* Not much on creativity
* How does creativity link to innovation?

(getting from creativity to innovation [von Oetinger, 2004])

* The process of strategy
+ Dynamics of strategic fit
# Modelling the dynamics of changes in strategic fit (Zajac, Kraatz & Bresser, 2000)
+ Organizational dynamics:
# Organizational inheritance (group think, strategic drift: constraints on new strategies) or managerial initiative (proactive role of managers on strategy)
# Chaos or control (predictable, unpredictability)
+ Organizational learning & unlearning (Huber, 1991)
+ Dynamic capabilities (Teece et al, 1997; Winter 2003)
# resource development and renewal ( c.f. resource- based view that is a static approach)
# evolution of the knowledge base

+ Change processes
# continuous or discontinuous
# revolutionary or evolutionary
# rational or unpredictable
# incremental or comprehensive
* role of MCS as move between different modes
+ Strategic decision speed
# speed of decision making (Baum, & Wally, 2003)
# presumptive adaptation (fast or gradual) (Gabriel & Jensen, 2006)
# the dynamic resource-based view, or capability lifecycles (Helfat & Peteraf 2003)

Accounting & Auditing Developments

Saturday, March 20th, 2010

Endowment Funds

* Definition – An established fund of cash, securities, or other assets to provide income for the maintenance of a not-for-profit entity (NFP)
* Use of assets may be permanently restricted, temporarily restricted, or unrestricted
* Generally established by donor-restricted gifts and bequests to provide either of the following:
o A permanent endowment – provides a permanent source of income
o A term endowment – provides income for a specified period
* Alternatively, an NFP’s governing board may earmark a portion of unrestricted net assets as a Board-Designated Endowment Fund
* The portion of an endowment to be maintained permanently is classified as permanently restricted net assets
* The portion of an endowment to be maintained for a specified term or purpose is classified as temporarily restricted net assets
* Funds that have no donor-imposed restrictions as to the use or purpose are classified as unrestricted net assets
o These funds may be earmarked and designated by the Board

UMIFA

The Uniform of Institutional Funds Act (1972)

* Developed and promulgated by the National Conference of Commissioners on Uniform State Laws (NCCUSL)
* Established uniform standards for the management, , and expenditure of the endowment funds of NFP institutions
o Prior to UMIFA, institutions could only spend a “prudent” amount of interest and dividends from an endowment

o UMIFA allowed the institution to include asset appreciation
o Allowed endowments to:
+ invest in any kinds of assets
+ pool endowment funds for investment purposes
+ delegate to other persons (professional investment advisors)
o Prohibited spending from an “underwater fund”

Underwater Fund

* Definition – A fund whose current value is below the value of the gift at the time it was given by the donor
* Under UMIFA, spending abilities from an underwater fund were limited until the fund regained historical dollar value (HDV)
* Limitations depended on state law:
o Could spend only interest and dividends
o Could spend at a reduced rate
o Could not spend at all

Disadvantages of UMIFA

* Market declines in 2001 and 2002 left institutions struggling to cover expected revenue from recently established endowments that had fallen below their HDV
* New endowments did not have sufficient time to appreciate before the funds were needed for operations
* Sufficient resources were available in the endowments
* However, rigid restrictions limited the institution’s ability to utilize those resources

Disadvantages of UMIFA

* Colleges and universities were forced to cut programs, lay off teachers, increase borrowings, and increase tuition

* Market declines in 2008 and 2009 are making the situation even worse

o Per a survey by the Association of Governing Boards:

What is the Uniform Prudent Management

of Institutional Funds Act (UPMIFA)?

Are you excited yet?

UPMIFA

Why the switch from UMIFA to UPMIFA?

* UMIFA is an old law…on the books since 1972

* Updates the “prudence standard” that applies to the management and investment of charitable funds
* Modernizes the rules governing expenditures from endowment funds
* Adopts provisions governing the release and modification of restrictions on charitable funds to permit more efficient management
