EFISIENSI PASAR - DEFINISI DAN UJI Apa pasar yang efisien Pasar yang efisien adalah pasar dimana harga pasar merupakan perkiraan tidak bias atas nilai investasi sebenarnya. Tersirat dalam derivasi ini adalah beberapa konsep kunci - (a) Efisiensi pasar tidak mensyaratkan bahwa harga pasar sama dengan nilai sebenarnya pada setiap titik waktu. Yang dibutuhkan adalah bahwa kesalahan dalam harga pasar tidak bias, yaitu bahwa harga bisa lebih besar dari atau kurang dari nilai sebenarnya, selama penyimpangan ini acak. (B) Fakta bahwa penyimpangan dari nilai sebenarnya secara acak menyiratkan, secara kasar, bahwa ada kemungkinan yang sama bahwa saham berada di bawah atau di atas bernilai pada setiap titik waktu, dan bahwa penyimpangan ini tidak berkorelasi dengan variabel yang dapat diamati. Misalnya, di pasar yang efisien, saham dengan rasio PE yang lebih rendah cenderung tidak lebih rendah nilainya dibandingkan saham dengan rasio PE tinggi. (C) Jika penyimpangan harga pasar dari nilai sebenarnya bersifat acak, maka tidak ada kelompok investor yang dapat secara konsisten menemukan di bawah atau di atas saham yang dinilai dengan menggunakan strategi investasi apapun. Efisiensi Pasar untuk Kelompok Investor Definisi efisiensi pasar harus spesifik tidak hanya mengenai pasar yang sedang dipertimbangkan tetapi juga kelompok investor yang tercakup. Sangat tidak mungkin semua pasar efisien bagi semua investor. Namun sangat mungkin bahwa pasar tertentu (misalnya, New York Stock Exchange) efisien berkenaan dengan investor rata-rata. Mungkin saja beberapa pasar efisien sementara pasar lain tidak, dan pasar efisien terhadap beberapa investor dan bukan pada orang lain. Ini adalah konsekuensi langsung dari tarif pajak diferensial dan biaya transaksi, yang memberikan keuntungan pada beberapa investor dibandingkan dengan yang lain. Definisi efisiensi pasar juga dikaitkan dengan asumsi tentang informasi apa yang tersedia bagi investor dan tercermin dalam harga. Misalnya, definisi ketat efisiensi pasar yang mengasumsikan bahwa semua informasi, publik maupun pribadi, tercermin dalam harga pasar akan menyiratkan bahwa bahkan investor dengan informasi dalam yang tepat tidak akan dapat mengalahkan pasar. Efisiensi Bentuk Kuat versus Lemah: - Di bawah efisiensi bentuk lemah. Harga saat ini mencerminkan informasi yang terdapat dalam semua harga masa lalu, menunjukkan bahwa grafik dan analisis teknis yang menggunakan harga masa lalu saja tidak akan berguna dalam menemukan saham yang bernilai tinggi. - Di bawah efisiensi bentuk semi kuat. Harga saat ini mencerminkan informasi yang terkandung tidak hanya di harga masa lalu tetapi semua informasi publik (termasuk laporan keuangan dan laporan berita) dan tidak ada pendekatan yang didasarkan pada penggunaan dan pemantauan informasi ini akan berguna dalam menemukan saham yang bernilai. - Di bawah efisiensi bentuk yang kuat. Harga saat ini mencerminkan semua informasi. Publik maupun swasta, dan tidak ada investor yang dapat secara konsisten menemukan saham yang bernilai. Implikasi efisiensi pasar Implikasi langsung dan langsung dari pasar yang efisien adalah tidak ada kelompok investor yang dapat secara konsisten mengalahkan pasar dengan menggunakan strategi investasi yang sama. Pasar yang efisien juga akan membawa implikasi yang sangat negatif bagi banyak strategi dan tindakan investasi yang dianggap remeh - (a) Di pasar yang efisien, penelitian dan valuasi ekuitas akan menjadi tugas mahal yang tidak memberikan keuntungan. Kemungkinan menemukan saham undervalued harus acak (5050). Paling banter, manfaat dari pengumpulan informasi dan penelitian ekuitas akan mencakup biaya dalam melakukan penelitian. (B) Di pasar yang efisien, strategi diversifikasi secara acak di seluruh saham atau pengindeksan ke pasar, membawa sedikit atau tanpa biaya informasi dan biaya eksekusi minimal, akan lebih unggul daripada strategi lainnya. Yang menciptakan informasi lebih besar dan biaya eksekusi. Tidak akan ada nilai tambah oleh manajer portofolio dan strategi investasi. (C) Di pasar yang efisien, strategi meminimalkan perdagangan. Yaitu menciptakan portofolio dan bukan trading kecuali uang tunai dibutuhkan, akan lebih unggul dari strategi yang sering dilakukan trading. Apa efisiensi pasar tidak menyiratkan: Pasar yang efisien tidak menyiratkan bahwa - (a) harga saham tidak dapat menyimpang dari nilai sebenarnya sebenarnya, dapat terjadi penyimpangan besar dari nilai sebenarnya. Satu-satunya persyaratan adalah bahwa penyimpangan menjadi acak. (B) tidak ada investor yang akan mengalahkan pasar dalam jangka waktu tertentu. Sebaliknya, sekitar setengah dari seluruh investor, sebelum biaya transaksi, harus mengalahkan pasar dalam periode apapun. (C) tidak ada kelompok investor yang akan mengalahkan pasar dalam jangka panjang. Mengingat jumlah investor di pasar keuangan, hukum probabilitas akan menunjukkan bahwa jumlah yang cukup besar akan mengalahkan pasar secara konsisten dalam waktu lama, bukan karena strategi investasi mereka tetapi karena mereka beruntung. Akan tetapi, hal itu tidak konsisten jika sejumlah besar investor tersebut menggunakan strategi investasi yang sama sekali tidak proporsional. Di pasar yang efisien, tingkat pengembalian investasi yang diharapkan akan konsisten dengan risiko investasi tersebut dalam jangka panjang, meskipun mungkin ada penyimpangan dari hasil yang diharapkan dalam jangka pendek ini. Kondisi yang diperlukan untuk efisiensi pasar Pasar tidak menjadi efisien secara otomatis. Ini adalah tindakan investor, merasakan penawaran dan menerapkan skema untuk mengalahkan pasar, yang membuat pasar menjadi efisien. Kondisi yang diperlukan untuk inefisiensi pasar yang harus dieliminasi adalah sebagai berikut - (1) Inefisiensi pasar harus menjadi dasar bagi skema untuk mengalahkan pasar dan mendapatkan keuntungan berlebih. Agar ini benar - (a) Aset (atau aset) yang merupakan sumber inefisiensi harus diperdagangkan. (B) Biaya transaksi pelaksanaan skema harus lebih kecil dari perkiraan keuntungan dari skema ini. (2) Harus ada keuntungan yang memaksimalkan investor yang (a) mengenali potensi pengembalian berlebih (b) dapat meniru mengalahkan skema pasar yang menghasilkan keuntungan berlebih (c) memiliki sumber daya untuk diperdagangkan pada saham sampai ketidakefisienan hilang Efisien Pasar dan Investor yang mencari keuntungan: Kontradiksi Internal Ada kontradiksi internal dalam mengklaim bahwa tidak ada kemungkinan pemukulan pasar di pasar yang efisien dan kemudian meminta investor yang memaksimalkan keuntungan untuk terus mencari cara untuk mengalahkan pasar dan dengan demikian membuatnya efisien. Jika pasar efisien, investor akan berhenti mencari inefisiensi. Yang akan menyebabkan pasar menjadi tidak efisien lagi. Masuk akal untuk memikirkan pasar yang efisien sebagai mekanisme koreksi diri. Di mana inefisiensi muncul dalam interval reguler namun hilang hampir seketika karena investor menemukannya dan memperdagangkannya. Proposisi tentang efisiensi pasar Proposisi 1: Probabilitas untuk menemukan inefisiensi di pasar aset menurun karena kemudahan perdagangan pada aset meningkat. Sejauh investor mengalami kesulitan melakukan perdagangan saham, baik karena pasar terbuka tidak ada atau ada hambatan signifikan dalam perdagangan, inefisiensi harga bisa berlanjut dalam waktu lama. Contoh: Saham versus real estat NYSE vs NASDAQ Proposisi 2: Probabilitas untuk menemukan inefisiensi di pasar aset meningkat karena biaya transaksi dan informasi untuk mengeksploitasi kenaikan inefisiensi. Biaya pengumpulan informasi dan perdagangan sangat bervariasi di pasar dan bahkan di investasi di pasar yang sama. Seiring kenaikan biaya ini, kurang dan sedikit untuk mencoba memanfaatkan inefisiensi ini. Penawaran Umum Perdana. IPO diduga melakukan imbal hasil rata-rata. Emerging Market Stocks. Apakah mereka membuat keuntungan berlebih Berinvestasi dalam saham yang kalah? Yaitu saham yang telah dilakukan dengan sangat buruk dalam beberapa periode waktu sebelumnya harus menghasilkan keuntungan berlebih. Biaya transaksi cenderung jauh lebih tinggi untuk saham ini karena - (a) mereka kemudian menjadi saham dengan harga rendah, yang mengarah ke komisi dan biaya perantara yang lebih tinggi (b) tawaran-ask menjadi bagian yang jauh lebih tinggi dari harga keseluruhan yang dibayarkan. (C) perdagangan sering tipis pada saham ini, dan perdagangan kecil dapat menyebabkan harga bergerak. Konsekuensi 1: Investor yang dapat menetapkan keuntungan biaya (baik dalam pengumpulan informasi atau biaya transaksi) akan lebih mampu mengeksploitasi inefisiensi kecil daripada investor lain yang tidak memiliki keuntungan ini. Contoh: Efek blok perdagangan terhadap harga saham para ahli di Lantai Bursa Menetapkan keuntungan biaya, terutama yang berkaitan dengan informasi, mungkin dapat menghasilkan keuntungan berlebih atas dasar keuntungan ini. Jadi, John Templeton, yang mulai berinvestasi di pasar Jepang dan pasar Asia yang lain jauh sebelum manajer portofolio lainnya, mungkin telah dapat memanfaatkan keuntungan informasi yang dia miliki dari rekan-rekannya untuk melakukan keuntungan berlebih pada portofolio-nya. Proposisi 3: Kecepatan yang tidak efisien akan langsung terkait dengan seberapa mudah skema untuk memanfaatkan inefisiensi dapat direplikasi oleh investor lain. Kemudahan dimana suatu skema dapat direplikasi, haknya berbanding terbalik dengan waktu, ketersediaan dan informasi yang dibutuhkan untuk menjalankannya. Karena hanya sedikit investor yang memiliki sumber daya untuk menghilangkan inefisiensi melalui perdagangan, kemungkinan besar inefisiensi akan cepat hilang jika skema yang digunakan untuk mengeksploitasi inefisiensi itu transparan dan dapat disalin oleh investor lain. Contoh: Berinvestasi pada pemecahan saham versus Indeks ArbitragePRICE EARNINGS MULTIPLES Mengapa rasio PE digunakan secara luas sehingga merupakan statistik yang secara intuitif menarik yang berkaitan dengan harga yang dibayarkan terhadap pendapatan lancar. Mudah untuk menghitung sebagian besar saham, dan tersedia secara luas, membuat perbandingan di antara saham sederhana. Ini adalah proxy untuk sejumlah karakteristik lain dari perusahaan termasuk risiko dan pertumbuhan. Potensi penyalahgunaan penggunaan rasio PE adalah suatu cara, bagi beberapa analis, untuk menghindari eksplisit mengenai asumsi mereka terhadap rasio risiko, pertumbuhan dan pembayaran. Mereka jauh lebih mungkin untuk mencerminkan suasana hati dan persepsi pasar, namun hal ini dapat dipandang sebagai kelemahan, terutama ketika pasar membuat kesalahan sistematis dalam menilai seluruh sektor. Memperkirakan rasio PE dari fundamental PE Ratio untuk perusahaan yang stabil Sebuah perusahaan yang stabil adalah perusahaan yang tumbuh pada tingkat yang sebanding dengan tingkat pertumbuhan nominal dalam ekonomi di mana ia beroperasi. Gordon Growth Model: P0 Nilai ekuitas DPS1 Dividen yang diharapkan per saham tahun depan r Tingkat pengembalian ekuitas yang disyaratkan Tingkat pertumbuhan dividen (selamanya) Dengan mensubstitusikan DPS1 EPS0 (1gn) (rasio pembayaran), nilai ekuitas dapat menjadi Ditulis sebagai: Ilustrasi 1: Memperkirakan rasio PE untuk perusahaan yang stabil dengan menggunakan DPS-Deutsche Bank AG Deutsche Bank memperoleh laba per saham sebesar 46,38 DM pada tahun 1994, dan membayar dividen sebesar 16,50 sebagai dividen pada tahun tersebut. Tingkat pertumbuhan pendapatan dan dividen, dalam jangka panjang, diperkirakan akan mencapai 6.

Versi beta untuk saham adalah 0,93. Tingkat bunga sepuluh tahun di Jerman adalah 7,5 dan premi risiko untuk saham di atas obligasi diasumsikan 4,50.

Rasio PE untuk perusahaan dengan pertumbuhan tinggi Rasio harga-pendapatan untuk perusahaan dengan pertumbuhan tinggi juga dapat dikaitkan dengan fundamental. Dalam kasus khusus dari model diskon dividen dua tahap, hubungan ini dapat dibuat eksplisit secara adil: EPS0 Laba per saham di tahun 0 (tahun berjalan) g Tingkat pertumbuhan pada n tahun pertama r Tingkat pengembalian modal yang disyaratkan dalam Pembayaran Payout Rasio pada n tahun pertama gn Laju pertumbuhan setelah n tahun selamanya (Tingkat pertumbuhan stabil) Rasio Payoutn Payoutn n tahun untuk perusahaan stabil Determinan rasio PE untuk perusahaan dengan pertumbuhan tinggi Sisi kiri dari persamaan tersebut adalah rasio pendapatan harga .

Ini adalah saham Kelas B, dengan hak suara terbatas. Rasio PE dan Pertumbuhan Luar Biasa yang Diharapkan Karena perusahaan mengantisipasi tingkat pertumbuhan luar biasa dalam lima tahun pertama yang mengalami penurunan dari 25 menjadi 8, rasio PE untuk perusahaan juga menurun dari 28,75 menjadi 15. Strategi Investasi yang membandingkan PE dengan tingkat pertumbuhan yang diharapkan Manajer portofolio dan Analis terkadang membandingkan rasio PE dengan tingkat pertumbuhan yang diharapkan untuk mengidentifikasi saham yang dinilai terlalu rendah. Dalam bentuk pendekatan yang paling sederhana, perusahaan dengan rasio PE kurang dari tingkat pertumbuhan yang diharapkan dipandang sebagai undervalued. Dalam bentuknya yang lebih umum, rasio rasio PE terhadap pertumbuhan digunakan sebagai ukuran nilai relatif. Masalah dengan membandingkan rasio PE dengan pertumbuhan yang diharapkan Dalam bentuknya yang sederhana, tidak ada dasar untuk mempercayai bahwa perusahaan tersebut dinilai rendah hanya karena memiliki rasio PE kurang dari perkiraan pertumbuhan. Hubungan ini mungkin konsisten dengan perusahaan yang dinilai cukup baik atau bahkan terlalu tinggi, jika suku bunga tinggi. Atau jika perusahaan memiliki risiko tinggi. Masalah dengan perbandingan relatif (PEg) Dalam bentuk relatifnya, di mana perusahaan diberi peringkat berdasarkan rasio rasio PE terhadap pertumbuhan yang diharapkan, rangking akan memberikan ukuran nilai relatif jika, Panjang periode pertumbuhan tinggi adalah Sama untuk semua perusahaan Semua perusahaan memiliki risiko setara. Jika model yang digunakan adalah CAPM, semua perusahaan memiliki beta yang sama. Rasio PE dari perusahaan yang lebih aman akan lebih tinggi daripada rasio PE dari perusahaan yang berisiko di setiap tingkat pertumbuhan, seperti yang diilustrasikan pada Gambar 14.4: Perbandingan Rasio PE Perbandingan di seluruh negara Perbandingan sering dibuat antara rasio harga-pendapatan di berbagai negara dengan Niat untuk menemukan pasar yang bernilai undervalued dan overvalued. Hal ini jelas menyesatkan dalam kasus ini untuk membandingkan rasio PE di pasar yang berbeda tanpa mengendalikan perbedaan variabel yang mendasarinya. CONTOH DENGAN PASAR EMERGING Perbandingan sepanjang waktu Perbandingan lain yang sering dilakukan adalah antara rasio PE sepanjang waktu. Karena fundamental (tingkat suku bunga dan pertumbuhan yang diharapkan) berubah seiring waktu, rasio PE juga akan berubah. Perbandingan yang lebih tepat karenanya tidak antara rasio PE sepanjang waktu, namun antara rasio PE aktual dan rasio PE yang diprediksi berdasarkan fundamental yang ada saat itu. Ada hubungan positif yang kuat antara rasio EP dan tingkat T. Bond. Terbukti dengan adanya korelasi antara 0,67 antara kedua variabel tersebut. Selain itu, ada bukti bahwa istilah struktur juga mempengaruhi rasio PE. Dalam regresi berikut, kami menurunkan rasio EP terhadap tingkat suku bunga T. Bond dan variabel struktur jangka (T. Bond - T. Bill rate) EP 3,34 0,7160 T. Bond Rate - 0,9039 (T. Bond Rate-T. Bill Rate) R 2 0,795 Hal-hal lain yang tersisa sama, regresi ini menunjukkan bahwa Setiap kenaikan 1 pada tingkat T. Bond meningkatkan rasio EP sebesar 0,716. Setiap kenaikan 1 perbedaan antara tingkat T. Bond dan T. Bill mengurangi rasio EP sebesar 0,90. (Dengan istilah struktur yang rata, rasio EP harus ditingkatkan - Rasio PE harus menurun) Membandingkan rasio PE di seluruh rasio PE perusahaan bervariasi di seluruh industri dan di seluruh perusahaan karena perbedaan fundamental - pertumbuhan yang lebih tinggi umumnya diterjemahkan ke dalam rasio PE yang lebih tinggi. Bila perbandingan dibuat di seluruh perusahaan, perbedaan tingkat risiko, tingkat pertumbuhan dan rasio pembayaran harus dikontrol secara eksplisit. Menggunakan perusahaan yang sebanding - Proporsi dan Kelemahan Pendekatan yang paling umum untuk memperkirakan rasio PE untuk perusahaan adalah memilih kelompok perusahaan yang sebanding, untuk menghitung rasio PE rata-rata untuk kelompok ini dan menyesuaikan secara subjektif rata-rata perbedaan antara perusahaan yang dinilai Dan perusahaan yang sebanding. Ada beberapa masalah dengan pendekatan ini. Definisi perusahaan yang sebanding pada dasarnya adalah subyektif. Penggunaan perusahaan lain di industri ini karena kelompok kontrol seringkali bukan solusi karena perusahaan dalam industri yang sama dapat memiliki campuran bisnis dan profil risiko dan pertumbuhan yang sangat berbeda. Ada juga banyak potensi bias. Bahkan ketika kelompok perusahaan sebanding yang sah dapat dibangun, perbedaan akan terus berlanjut dalam fundamental antara perusahaan yang dihargai dan kelompok ini. Dengan menggunakan keseluruhan crosssection: Pendekatan regresi Berbeda dengan pendekatan perusahaan yang sebanding, informasi di keseluruhan bagian lintas perusahaan dapat digunakan untuk memprediksi rasio PE. Cara termudah untuk meringkas informasi ini adalah dengan regresi berganda. Dengan rasio PE sebagai variabel dependen, dan proxy untuk risiko, pertumbuhan dan pembayaran membentuk variabel independen. Regresi rasio PE ini telah diperbarui pada bagian berikut dengan menggunakan data dari tahun 1987 sampai 1991. Basis data COMPUSTAT digunakan untuk mengambil informasi mengenai rasio pendapatan-harga, rasio pembayaran dan pendapatan Manajemen Risiko Nilai Tukar oleh Ian H. Giddy dan Gunter Dufey Universitas New York dan University of Michigan 1 (a) Tujuan dari bab ini adalah risiko Exchange adalah Pengaruh perubahan kurs yang tidak diantisipasi terhadap nilai perusahaan. Bab ini membahas dampak fluktuasi mata uang terhadap arus kas, aset dan kewajiban, dan pada bisnis nyata perusahaan. Tiga pertanyaan harus ditanyakan. Pertama, risiko pertukaran apa yang dihadapi perusahaan, dan metode apa yang tersedia untuk mengukur eksposur mata uang Kedua, berdasarkan sifat eksposur dan kemampuan perusahaan untuk meramalkan mata uang, strategi pengelolaan risiko lindung nilai atau pertukaran apa yang harus diterapkan perusahaan Dan akhirnya, Mana dari berbagai alat dan teknik pasar valuta asing yang harus dipekerjakan: hutang dan aset ke depan dan masa depan dan opsi. Bab ini diakhiri dengan menyarankan sebuah kerangka kerja yang dapat digunakan untuk mencocokkan instrumen dengan masalah tersebut. 1 (b) Berapakah risiko nilai tukar Exchange yang sederhana dalam konsep: potensi keuntungan atau kerugian yang terjadi sebagai akibat dari perubahan nilai tukar. Misalnya, jika seseorang memiliki saham di Hitachi, perusahaan Jepang, dia akan kehilangan jika nilai yen turun. Namun dari pertanyaan sederhana ini muncul lagi. Pertama, yang keuntungan atau kerugiannya Jelas bukan hanya anak perusahaan, karena dapat diimbangi oleh posisi yang diambil di tempat lain di perusahaan. Dan bukan hanya keuntungan atau kerugian pada transaksi berjalan, karena nilai perusahaan terdiri dari arus kas masa depan yang diantisipasi dan juga yang dikontrak. Yang penting, keuangan modern mengatakan kepada kita, adalah nilai pemegang saham namun dampak dari perubahan mata uang tertentu terhadap nilai pemegang saham sulit untuk dinilai, jadi proxy harus digunakan. Bukti akademis yang menghubungkan perubahan kurs terhadap harga saham lemah. Selain itu, pemegang saham yang memiliki portofolio terdiversifikasi mungkin merasa bahwa dampak negatif dari perubahan nilai tukar pada satu perusahaan diimbangi oleh keuntungan di perusahaan lain dengan kata lain, bahwa risiko pertukaran dapat di diversifikasi. Jika memang demikian, dari pada itu mungkin tidak berisiko. Akhirnya, risiko bukanlah risiko jika diantisipasi. Di sebagian besar mata uang ada kontrak futures atau forward exchange yang harga memberi indikasi pada suatu perusahaan dimana pasar mengharapkan mata uang untuk pergi. Dan kontrak ini menawarkan kemampuan untuk mengunci perubahan yang diantisipasi. Jadi mungkin konsep risiko pertukaran yang lebih baik adalah perubahan nilai tukar yang tidak diantisipasi. Isu-isu ini dan lainnya membenarkan pandangan lebih dekat pada bidang pengelolaan keuangan internasional ini. 2 HARAPAN PERUSAHAAN MENGELOLA RISIKO BURSA ASING Banyak perusahaan menahan diri dari pengelolaan aktif eksposur valuta asing mereka, meskipun mereka mengerti bahwa fluktuasi nilai tukar dapat mempengaruhi pendapatan dan nilai mereka. Mereka membuat keputusan ini karena sejumlah alasan. Pertama, manajemen tidak memahaminya. Mereka mempertimbangkan penggunaan alat manajemen risiko, seperti forward, futures dan options, spekulatif. Atau mereka berpendapat bahwa manipulasi keuangan semacam itu ada di luar bidang keahlian perusahaan. Kami berada dalam bisnis pembuatan mesin slot, dan kita seharusnya tidak berjudi dengan mata uang. Mungkin mereka benar takut melanggar teknik lindung nilai, namun menolak untuk menggunakan ke depan dan instrumen lainnya dapat mengekspos perusahaan tersebut pada risiko spekulatif yang substansial. Kedua, mereka mengklaim bahwa paparan tidak dapat diukur. Mereka benar - eksposur mata uang sangat kompleks dan jarang bisa diukur dengan presisi. Tapi seperti dalam banyak situasi bisnis, ketidaktepatan seharusnya tidak dijadikan alasan untuk keraguan. Ketiga, mereka mengatakan bahwa perusahaan itu dilindung nilai. Semua transaksi seperti impor atau ekspor ditutupi, dan anak perusahaan asing membiayai dalam mata uang lokal. Ini mengabaikan fakta bahwa sebagian besar nilai perusahaan berasal dari transaksi yang belum selesai, sehingga lindung nilai transaksi merupakan strategi yang sangat tidak lengkap. Keempat, mereka mengatakan bahwa perusahaan tersebut tidak memiliki risiko pertukaran karena melakukan semua bisnisnya dalam dolar (atau yen, atau berapa pun mata uang rumah). Tapi beberapa saat yang dipikirkan akan membuat jelas bahwa bahkan jika Anda menagih pelanggan Jerman dalam dolar, saat tanda tersebut menurunkan harga Anda harus menyesuaikan atau Anda akan dilemahkan oleh pesaing lokal. Jadi pendapatan dipengaruhi oleh perubahan mata uang. Akhirnya, mereka menyatakan bahwa neraca dilindung nilai berdasarkan akuntansi - terutama bila mata uang fungsional dianggap sebagai dolar. Sinyal yang menyesatkan bahwa pengukuran paparan neraca dapat diberikan didokumentasikan di bagian selanjutnya. Tapi adakah pembenaran ekonomi untuk strategi tidak melakukan apa pun. Prinsip modern teori keuangan menyarankan prima facie bahwa pengelolaan eksposur valuta asing perusahaan mungkin tidak menjadi perhatian penting atau tidak sah. Telah diperdebatkan, dalam tradisi Teorema Modigliani-Miller, bahwa firma tersebut tidak dapat memperbaiki nilai pemegang saham dengan manipulasi keuangan: secara khusus, investor sendiri dapat melakukan lindung nilai atas pemaparan perusahaan dengan menerbitkan kontrak berjangka sesuai dengan kepemilikan mereka di sebuah perusahaan. Manajer tidak melayani mereka dengan menebak-nebak apa yang pemegang risiko ingin lindung nilai. Satu kontra-argumen adalah bahwa biaya transaksi biasanya lebih besar bagi investor perorangan daripada perusahaan. Namun ada alasan yang lebih dalam mengapa risiko nilai tukar valuta asing harus dikelola pada tingkat perusahaan. Seperti yang akan ditunjukkan dalam materi berikut, penilaian eksposur terhadap fluktuasi nilai tukar memerlukan perkiraan terperinci mengenai kerentanan arus kas bersih terhadap perubahan nilai tukar yang tidak terduga (Dufey dan Srinivasulu, 1983). Manajer operasi dapat membuat perkiraan seperti itu dengan lebih presisi daripada pemegang saham yang biasanya tidak memiliki pengetahuan terperinci mengenai persaingan, pasar, dan teknologi yang relevan. Lebih jauh lagi, di semua kecuali pasar keuangan yang paling sempurna, perusahaan memiliki keuntungan yang cukup besar daripada investor dalam mendapatkan hutang yang relatif murah di dalam dan di luar negeri, mengambil keuntungan maksimal dari subsidi bunga dan meminimalkan dampak pajak dan risiko politik. Bidang penalaran lain menunjukkan bahwa manajemen risiko valuta asing tidak masalah karena kondisi ekuilibrium tertentu di pasar internasional baik untuk aset finansial maupun real. Kondisi ini termasuk hubungan antara harga barang di pasar yang berbeda, yang lebih dikenal dengan Purchasing Power Parity (PPP), dan antara tingkat suku bunga dan nilai tukar, biasanya disebut sebagai International Fisher Effect (lihat bagian selanjutnya). Namun, penyimpangan dari PPP dan IFE dapat bertahan dalam jangka waktu yang cukup lama, terutama pada tingkat perusahaan individual. Variabilitas arus kas bersih yang dihasilkan sangat penting karena dapat menyebabkan perusahaan mengalami biaya tekanan finansial. Atau bahkan gagal bayar. Penelitian modern di bidang keuangan mendukung penalaran bahwa fluktuasi pendapatan yang mengancam kelangsungan usaha perusahaan menyerap waktu pengelolaan dan kreditur, memerlukan biaya di luar saku seperti biaya hukum, dan menciptakan berbagai masalah operasi dan investasi, termasuk investasi yang kurang dalam RampD. Argumen yang sama mendukung pentingnya manajemen risiko pertukaran korporasi terhadap klaim bahwa di pasar ekuitas hanya risiko sistematis yang penting. Sejauh risiko valuta asing mewakili risiko yang tidak sistematis, hal itu tentu saja dapat terdiversifikasi - diberikan lagi, bahwa investor memiliki kualitas informasi yang sama tentang perusahaan sebagai manajemen - suatu kondisi yang tidak mungkin berlaku dalam praktik. Alasan ini ditopang oleh kemungkinan dampak risiko pertukaran terhadap pajak yang dibayar oleh perusahaan. Umumnya disepakati bahwa leverage melindungi perusahaan dari pajak, karena bunga dikurangkan dari pajak sedangkan dividen tidak. Namun sejauh mana perusahaan dapat meningkatkan leverage dibatasi oleh risiko dan biaya kebangkrutan. Perusahaan yang lebih berisiko, mungkin orang yang tidak melakukan lindung nilai terhadap risiko pertukaran, tidak dapat meminjam sebanyak mungkin. Dengan demikian, apa pun yang mengurangi probabilitas kebangkrutan memungkinkan perusahaan mengambil leverage yang lebih besar, sehingga membayar lebih sedikit pajak untuk arus kas operasi yang diberikan. Jika hedging valuta asing mengurangi pajak, pemegang saham mendapat keuntungan dari lindung nilai. Namun, ada satu tugas yang tidak dapat dilakukan oleh perusahaan untuk pemegang saham: sejauh individu menghadapi risiko pertukaran unik sebagai akibat dari pola pengeluaran mereka yang berbeda-beda, mereka harus merancang strategi lindung nilai yang sesuai. Manajemen risiko devisa perusahaan dalam pengertian tradisional hanya mampu melindungi tingkat pengembalian nominal yang diharapkan dalam mata uang referensi (Eaker, 1981). 3 PEKERJAAN EKONOMI, PEMBELIAN PEKERJAAN DAYA DAN EFEK PERIKANAN INTERNASIONAL Nilai tukar, suku bunga dan tingkat inflasi saling terkait satu sama lain melalui serangkaian hubungan klasik yang memiliki sifat impor dari risiko selisih kurs perusahaan. Hubungan ini adalah: (1) teori paritas daya beli, yang menggambarkan keterkaitan antara tingkat inflasi relatif dan nilai tukar (2) efek Fisher internasional. Yang menghubungkan perbedaan tingkat suku bunga dengan ekspektasi nilai tukar dan (3) teori tingkat bias yang tidak bias. Yang menghubungkan nilai tukar ke depan dengan ekspektasi nilai tukar. Hubungan ini, bersama dengan dua hubungan paritas kunci lainnya, diilustrasikan pada Gambar 1. Teori Purchasing Power Parity (PPP) dapat dinyatakan dengan cara yang berbeda, namun representasi yang paling umum menghubungkan perubahan nilai tukar dengan indeks harga relatif di Dua negara Tingkat perubahan nilai tukar Perbedaan tingkat inflasi Hubungan berasal dari gagasan dasar bahwa, dengan tidak adanya pembatasan perdagangan perubahan dalam perubahan nilai tukar cermin di tingkat harga relatif di kedua negara. Pada saat bersamaan, dalam kondisi perdagangan bebas, harga komoditas serupa tidak dapat berbeda antara dua negara, karena arbitrase akan memanfaatkan situasi tersebut sampai perbedaan harga dieliminasi. Hukum Harga Satu ini mengarah secara logis pada gagasan bahwa apa yang benar dari satu komoditas seharusnya benar bagi ekonomi secara keseluruhan - tingkat harga di dua negara harus dikaitkan melalui nilai tukar - dan oleh karena itu, bahwa pertukaran Tingkat perubahan terkait dengan perbedaan tingkat inflasi. The International Fisher Effect (IFE) menyatakan bahwa perbedaan suku bunga akan ada hanya jika nilai tukar diperkirakan akan berubah sedemikian rupa sehingga keuntungan dari suku bunga yang lebih tinggi diimbangi oleh kerugian pada transaksi valuta asing. Pengaruh Fisher Internasional ini dapat ditulis sebagai berikut: Tingkat perubahan nilai tukar yang diharapkan Perbedaan suku bunga Secara praktis, IFE menyiratkan bahwa sementara seorang investor di negara dengan bunga rendah dapat mengubah proporsinya menjadi mata uang high - Bunga negara dan mendapat bayaran yang lebih tinggi, keuntungannya (differential rate differential) akan diimbangi oleh expected loss karena perubahan nilai tukar mata uang asing. Teori Tingkat Forward Teruskan menegaskan bahwa nilai tukar ke depan adalah perkiraan nilai tukar spot masa depan yang terbaik dan tidak bias. Teori ini didasarkan pada teori pasar yang efisien, dan secara luas diasumsikan dan diperdebatkan secara luas sebagai penjelasan yang tepat. Tingkat yang diharapkan hanya rata-rata namun teori pasar efisien mengatakan bahwa ini adalah harapan yang tidak bias - bahwa ada probabilitas yang sama dari tingkat aktual yang berada di atas atau di bawah nilai yang diharapkan. Teori tingkat bias yang tidak bias dapat dinyatakan secara sederhana: Nilai tukar yang diharapkan Nilai tukar masa depan Sekarang kita dapat merangkum dampak perubahan nilai tukar yang tidak terduga pada perusahaan yang terlibat secara internasional dengan memanfaatkan kondisi paritas ini. Given sufficient time, competitive forces and arbitrage will neutralize the impact of exchange rate changes on the returns to assets due to the relationship between rates of devaluation and inflation differentials, these factors will also neutralize the impact of the changes on the value of the firm This is simply the principle of Purchasing Power Parity and the Law of One Price operating at the level of the firm. On the liability side, the cost of debt tends to adjust as debt is repriced at the end of the contractual period, reflecting (revised) expected exchange rate changes. And returns on equity will also reflect required rates of return in a competitive market these will be influenced by expected exchange rate changes. Finally the unbiased forward rate theory suggests that locking in the forward exchange rate offers the same expected return as remaining exposed to the ups and downs of the currency -- on average, it can be expected to err as much above as below the forward rate. In the long run, it would seem that a firm operating in this setting will not experience net exchange losses or gains. However, because of contractual, or, more importantly, strategic commitments, these equilibrium conditions rarely hold in the short and medium term. Therefore the essence of foreign exchange exposure, and, significantly, its management, are made relevant by these temporary deviations. 4 IDENTIFYING EXPOSURE . The first step in management of corporate foreign exchange risk is to acknowledge that such risk does exist and that managing it is in the interest of the firm and its shareholders. The next step, however, is much more difficult: the identification of the nature and magnitude of foreign exchange exposure. In other words, identifying what is at risk, and in what way. The focus here is on the exposure of nonfinancial corporations, or rather the value of their assets. This reminder is necessary because most commonly accepted notions of foreign exchange risk hedging deal with assets, i. e. they are pertinent to (simple) financial institutions where the bulk of the assets consists of (paper) assets that have with contractually fixed returns, i. e. fixed income claims, not equities. Clearly, such timece your assets in the currency in which they are denominated applies in general to banks and similar firms. Nonfinancial business firms, on the other hand, have, as a rule, only a relatively small proportion of their total assets in the form of receivables and other financial claims. Their core assets consist of inventories, equipment, special purpose buildings and other tangible assets, often closely related to technological capabilities that give them earnings power and thus value. Unfortunately, real assets (as compared to paper assets) are not labelled with currency signs that make foreign exchange exposure analysis easy. Most importantly, the location of an asset in a country is -- as we shall see -- an all too fallible indicator of their foreign exchange exposure. The task of gauging the impact of exchange rate changes on an enterprise begins with measuring its exposure . that is, the amount, or value, at risk. This issue has been clouded by the fact that financial results for an enterprise tend to be compiled by methods based on the principles of accrual accounting. Unfortunately, this approach yields data that frequently differ from those relevant for business decision-making, namely future cash flows and their associated risk profiles. As a result, considerable efforts are expended -- both by decision makers as well as students of exchange risk -- to reconcile the differences between the point-in-time effects of exchange rate changes on an enterprise in terms of accounting data, referred to as accounting or translation exposure . and the ongoing cash flow effects which are referred to as economic exposure . Both concepts have their grounding in the fundamental concept of transactions exposure . The relationship between the three concepts is illustrated in the Exhibit 2. While exposure concepts have been aptly analyzed elsewhere in this Handbook . some basic concepts are repeated here to make the present chapter self contained. 4 (a) Exposure in a simple transaction. The typical illustration of transaction exposure involves an export or import contract giving rise to a foreign currency receivable or payable. On the surface, when the exchange rate changes, the value of this export or import transaction will be affected in terms of the domestic currency. However, when analyzed carefully, it becomes apparent that the exchange risk results from a financial investment (the foreign currency receivable) or a foreign currency liability (the loan from a supplier) that is purely incidental to the underlying export or import transaction it could have arisen in and of itself through independent foreign borrowing and lending. Thus, what is involved here are simply foreign currency assets and liabilities, whose value is contractually fixed in nominal terms. While this traditional analysis of transactions exposure is correct in a narrow, formal sense, it is really relevant for financial institutions, only. With returns from financial assets and liabilities being fixed in nominal terms, they can be shielded from losses with relative ease through cash payments in advance (with appropriate discounts), through the factoring of receivables, or via the use of forward exchange contracts, unless unexpected exchange rate changes have a systematic effect on credit risk.8 However, the essential assets of nonfinancial firms have noncontractual returns, i. e. revenue and cost streams from the production and sale of their goods and services which can respond to exchange rate changes in very different ways. Consequently, they are characterized by foreign exchange exposure very different from that of firms with contractual returns. MEASURES OF ACCOUNTING EXPOSURE Note: In the case of Income Statements, sales revenues and interest are generally translated at the average historical exchange rate that prevailed during the period depreciation is translated at the appropriate historical exchange rate. Some of the general and administrative expenses as well as cost-of-goods-sold are translated at historical exchange rates, others at current rates. C Assets and liabilities are translated at the current rate, or rate prevailing on the date of the balance sheet. H Assets and liabilities are translated at the historical rate. 4 (b) Accounting exposure. The concept of accounting exposure arises from the need to translate accounts that are denominated in foreign currencies into the home currency of the reporting entity. Most commonly the problem arises when an enterprise has foreign affiliates keeping books in the respective local currency. For purposes of consolidation these accounts must somehow be translated into the reporting currency of the parent company. In doing this, a decision must be made as to the exchange rate that is to be used for the translation of the various accounts. While income statements of foreign affiliates are typically translated at a periodic average rate, balance sheets pose a more serious challenge. To a certain extent this difficulty is revealed by the struggle of the accounting profession to agree on appropriate translation rules and the treatment of the resulting gains and losses. A comparative historical analysis of translation rules may best illustrate the issues at hand. Over time, U. S. companies have followed essentially four types of translation methods, summarized in Exhibit 3. These four methods differ with respect to the presumed impact of exchange rate changes on the value of individual categories of assets and liabilities. Accordingly, each method can be identified by the way in which it separates assets and liabilities into those that are exposed and are, therefore, translated at the current rate, i. e. the rate prevailing on the date of the balance sheet, and those whose value is deemed to remain unchanged, and which are, therefore, translated at the historical rate. The currentnoncurrent method of translation divides assets and liabilities into current and noncurrent categories, using maturity as the distinguishing criterion only the former are presumed to change in value when the local currency appreciates or depreciates vis-agrave-vis the home currency. Supporting this method is the economic rationale that foreign exchange rates are essentially fixed but subject to occasional adjustments that tend to correct themselves in time. This assumption reflected reality to some extent, particularly with respect to industrialized countries during the period of the Bretton Woods system. However, with subsequent changes in the international financial environment, this translation method has become outmoded only in a few countries is it still being used. Under the monetarynonmonetary method all items explicitly defined in terms of monetary units are translated at the current exchange rate, regardless of their maturity. Nonmonetary items in the balance sheet, such as tangible assets, are translated at the historical exchange rate. The underlying assumption here is that the local currency value of such assets increases (decreases) immediately after a devaluation (revaluation) to a degree that compensates fully for the exchange rate change. This is equivalent of what is known in economics as the Law of One Price, with instantaneous adjustment. A similar but more sophisticated translation approach supports the so-called temporal method. Here, the exchange rate used to translate balance sheet items depends on the valuation method used for a particular item in the balance sheet. Thus, if an item is carried on the balance sheet of the affiliate at its current value, it is to be translated using the current exchange rate. Alternatively, items carried at historical cost are to be translated at the historical exchange rate. As a result, this method synchronizes the time dimension of valuation with the method of translation. As long as foreign affiliates compile balance sheets under traditional historical cost principles, the temporal method gives essentially the same results as the monetarynonmonetary method. However, when current value accounting is used, that is, when accounts are adjusted for inflation, then the temporal method calls for the use of the current exchange rate throughout the balance sheet. The temporal method provided the conceptual base for the Financial Accounting Standard Boards Standard 8 (FAS 8), which came into effect in 1976 for all U. S.-based companies and those non-U. S. companies that had to follow U. S. accounting principles in order to raise funds in the public markets of the United States. The temporal method points to a more general issue: the relationship between translation and valuation methods for accounting purposes. When methods of valuation provide results that do not reflect economic reality, translation will fail to remedy that deficiency, but will tend to make the distortion very apparent. To illustrate this point: companies with real estate holdings abroad financed by local currency mortgages found that under FAS 8 their earnings were subject to considerable translation losses and gains. This came about because the value of their assets remained constant, as they were carried on the books at historical cost and translated at historical exchange rates, while the value of their local currency liabilities increased or decreased with every twitch of the exchange rate between reporting dates. In contrast, U. S. companies whose foreign affiliates produced internationally traded goods (minerals or oil, for example) felt very comfortable valuing their assets on a dollar basis. Indeed, this later category of companies were the ones that did not like the transition to the current rate method at all. Here, all assets and liabilities are translated at the exchange rate prevailing on the reporting date. They found the underlying assumption that the value of all assets (denominated in the local currency of the given foreign affiliate) would change in direct proportion to the exchange rate change did not reflect the economic realities of their business. In order to accommodate the conflicting requirements of companies in different situations and still maintain a semblance of conformity and comparability, at the end of 1981 the Financial Accounting Standards Board issued Standard 52, replacing Standard 8. FAS 52 . as it is commonly referred to, uses the currentcurrent method as the basic translation rule. At the same time it mitigates the consequences by allowing companies to move translation losses directly to a special subaccount in the net worth section of the balance sheet, instead of adjusting current income. This latter provision may be viewed as a mere gimmick without much substance, providing at best a signalling function, indicating to users of accounting information that translation gains and losses are of a nature different from items normally found in income statements. A more significant innovation of FAS 52 is the functional currency concept, which gives a company the opportunity to identify the primary economic environment and select the appropriate (functional) currency for each of the corporations foreign entities. This approach reflects the official recognition by the accounting profession that the location of an entity does not necessarily indicate the currency relevant for a particular business. Thus FAS 52 represents an attempt to take into account the fact that exchange rate changes affect different companies in different ways, and that rigid and general rules treating different circumstances in the same manner will provide misleading information. In order to adjust to the diversity of real life FAS 52 had to become quite complex. The following provides a brief road map to the logic of that standard. In applying FAS 52 a company and its accountants must make two decisions in sequence. First, they must determine the functional currency of the entity whose accounts are to be consolidated. For all practical purposes, the choice here is between local currency and the U. S. dollar. In essence, there are a number of specific criteria which provide guidelines for this determination. As usual, extreme cases are relatively easily classified: a foreign affiliate engaged in retailing local goods and services will have the local currency as its functional currency, while a border plant that receives the majority of its inputs from abroad and ships the bulk of the output outside of the host country will have the dollar as its functional currency. If the functional currency is the dollar, foreign currency items on its balance sheet will have to be restated into dollars and any gains and losses are moved through the income statement, just as under FAS 8. If, on the other hand, the functional currency is determined to be the local currency, a second issue arises: whether or not the entity operates in a high inflation environment. High inflation countries are defined as those whose cumulative three-year inflation rate exceeds 100 percent. In that case, essentially the same principles as in FAS 8 are followed. In the case where the cumulative inflation rate falls short of 100 percent, the foreign affiliates books are to be translated using the current exchange rate for all items, and any gains or losses are to go directly as a charge or credit to the equity accounts. FAS 52 has a number of other fairly complex provisions regarding the treatment of hedge contracts, the definition of transactional gains and losses, and the accounting for intercompany transactions. In essence, FAS 52 allows management much more flexibility to present the impact of exchange rate variations in accordance with perceived economic reality by the same token, it provides greater scope for manipulation of reported earnings and it reduces comparability of financial data for different firms. 4 (d) Critique of the Accounting Model of Exposure Even with the increased flexibility of FAS 52, users of accounting information must be aware that there are three system sources of error that can mislead those responsible for exchange risk management (Adler, 1982): 1. Accounting data do not capture all commitments of the firm that give rise to exchange risk. 2. Because of the historical cost principle, accounting values of assets and liabilities do not reflect the respective contribution to total expected net cash flow of the firm. 3. Translation rules do not distinguish between expected and unexpected exchange rate changes. Regarding the first point, it must be recognized that normally, commitments entered into by the firm in terms of foreign exchange, a purchase or a sales contract, for example, will not be booked until the merchandise has been shipped. At best, such obligations are shown as contingent liabilities. More importantly, accounting data reveals very little about the ability of the firm to change costs, prices and markets quickly. Alternatively, the firm may be committed by strategic decisions such as investment in plant and facilities. Such commitments are important criteria in determining the existence and magnitude of exchange risk. The second point surfaced in our discussion of the temporal method: whenever asset values differ from market values, translation--however sophisticated--will not redress this original shortcoming. Thus, many of the perceived problems of FAS 8 had their roots not so much in translation, but in the fact that in an environment of inflation and exchange rate changes, the lack of current value accounting frustrates the best translation efforts. Finally, translation rules do not take account of the fact that exchange rate changes have two components: (1) expected changes that are already reflected in the prices of assets and the costs of liabilities (relative interest rates) and (2) the real goods and services . the basic rationale for corporate foreign exchange exposure management is to shield net cash flows, and thus the value of the enterprise, from unanticipated exchange rate changes. This thumbnail sketch of the economic foreign exchange exposure concept has a number of significant implications, some of which seem to be at variance with frequently used ideas in the popular literature and apparent practices in business firms. Specifically, there are implications regarding (1) the question of whether exchange risk originates from monetary or nonmonetary transactions, (2) a reevaluation of traditional perspectives such as transactions risk, and (3) the role of forecasting exchange rates in the context of corporate foreign exchange risk management. 4 (f) Contractual versus Noncontractual Returns An assessment of the nature of the firms assets and liabilities and their respective cash flows shows that some are contractual, i. e. fixed in nominal, monetary terms. Such returns, earnings from fixed interest securities and receivables, for example, and the negative returns on various liabilities are relatively easy to analyze with respect to exchange rate changes: when they are denominated in terms of foreign currency, their terminal value changes directly in proportion to the exchange rate change. Thus, with respect to financial items, the firm is concerned only about net assets or liabilities denominated in foreign currency, to the extent that maturities (actually, durations of asset classes) are matched. What is much more difficult, however, is to gauge the impact of an exchange rate change on assets with noncontractual returns. While conventional discussions of exchange risk focus almost exclusively on financial assets, for trading and manufacturing firms at least, such assets are relatively less important than others. Indeed, equipment, real estate, buildings and inventories make the decisive contribution to the total cash flow of those firms. (Indeed companies frequently sell financial assets to banks, factors, or captive finance companies in order to leave banking to bankers and instead focus on the management of core assets) And returns on such assets are affected in quite complex ways by changes in exchange rates. The most essential consideration is how the prices and costs of the firm will react in response to an unexpected exchange rate change. For example, if prices and costs react immediately and fully to offset exchange rate changes, the firms cash flows are not exposed to exchange risk since they will not be affected in terms of the base currency. Example of the Effect of Devaluation on Inventory Assume the French subsidiary of a U. S. corp. has an inventory destined for sale to Germany. Exchange rates are as follows: before devaluation 1 FF .15 .30 DM after devaluation 1 FF .12 .20 DM WHAT DOES THE EFFECT OF EXCHANGE RATE CHANGES ON OPERATIONAL CASH FLOWS DEPEND ON 1. VOLUME EFFECTS (compensate for changes in profit margins) 2. PRICING FLEXIBILITY (change in margins to offset effect of exchange rate change) 3. DIVERSIFICATION of markets for inputs and outputs 4. PRODUCTION AND SALES FLEXIBILITY (ability to shift markets and sources quickly) Inventories may serve as a good illustration of this proposition. The value of an inventory in a foreign subsidiary is determined not only by changes in the exchange rate, but also by a subsequent price change of the product--to the extent that the underlying cause of this price change is the exchange rate change. Thus, the dollar value of an inventory destined for export may increase when the currency of the destination country appreciates, provided its local currency prices do not decrease by the full percentage of the appreciation. Exhibit 4 provides a numerical illustration. The effect on the local currency price depends, in part, on competition in the market. The behavior of foreign and local competitors, in turn, depends on capacity utilization, market share objectives, likelihood of cost adjustments and a host of other factors. Of course, firms are not only interested in the value change or the behavior of cash flows of a single asset, but rather in the behavior of all cash flows. Again, price and cost adjustments need to be analyzed. For example, a firm that requires raw materials from abroad for production will usually find its stream of cash outlays going up when its local currency depreciates against foreign currencies. Yet the depreciation may cause foreign suppliers to lower prices in terms of foreign currencies for the purpose of maintaining market share. WHAT IS ECONOMIC EXPOSURE PDVSA, the Venezuelan state-owned oil company, recently set up an oil refinery near Rotterdam, The Netherlands for shipment to Germany and other continental European countries. The firm planned to invoice its clients in ECU, the official currency unit of the European Community. The treasurer is considering sources of long term financing. In the past all long term finance has been provided by the parent company, but working capital required to pay local salaries and expenses has been financed in Dutch guilders. The treasurer is not sure whether the short term debt should be hedged, or what currency to issue long term debt in. This is an example of a situation where the definition of exposure has a direct impact on the firms hedging decisions. Translation exposure has to do with the location of the assets . which in this case would be a totally misleading measure of the effect of exchange rate changes on the value of the unit. After all, the oil comes from Venezuela and is shipped to Germany: its temporary resting place, be it a refinery in Rotterdam or a tanker en route to Germany, has no import. Both provide value added, but neither determine the currency of revenues. So financing should definitely not be done in Dutch guilders. Transactions exposure has to do with the currency of denomination of assets like accounts receivable or payable. Once sales to Germany have been made and invoicing in ECU has taken place, PDVSA-Netherlands has contractual, ECU-denominated assets that should be financed or hedged with ECU. For future sales, however, PDVSA-Netherlands does not have exposure to the ECU. This is because the currency of determination is the U. S. dollar. Economic exposure is tied to the currency of determination of revenues and costs. Since the world market price of oil is dollars, this is the effective currency in which PDVSAs future sales to Germany are made. If the ECU rises against the dollar, PDVSA must adjust its ECU price down to match those of competitors like Aramco. If the dollar rises against the ECU, PDVSA can and should raise prices to keep the dollar price the same, since competitors would do likewise. Clearly the currency of determination is influenced by the currency in which competitors denominate prices. 4 (g) Currency of denomination versus currency of determination One of the central concepts of modern international corporate finance is the distinction between the currency in which cash flows are denominated and the currency that determines the size of the cash flows. In the example in the previous section, it does not matter whether, as a matter of business practice, the firm may contract, be invoiced in, and pay for each individual shipment in its own local currency. If foreign exporters do not provide price concessions, the cash outflow of the importer behaves just like a foreign currency cash flow even though payments are made in local currency, they occur in greater amounts. As a result, the cash flow, even while denominated in local currency, is determined by the relative value of the foreign currency. The functional currency concept introduced in FAS 52 is similar to the currency of determination -- but not exactly. The currency of determination refers to revenue and operating expense flows, respectively the functional currency concept pertains to an entity as a whole, and is, therefore, less precise. To complicate things further, the currency of recording . that is, the currency in which the accounting records are kept, is yet another matter. For example, any debt contracted by the firm in foreign currency will always be recorded in the currency of the country where the corporate entity is located . However, the value of its legal obligation is established in the currency in which the contract is denominated. An example of the importance of these distinctions may be found in Exhibit 5. It is possible, therefore, that a firm selling in export markets may record assets and liabilities in its local currency and invoice periodic shipments in a foreign currency and yet, if prices in the market are dominated by transactions in a third country, the cash flows received may behave as if they were in that third currency. To illustrate: a Brazilian firm selling coffee to West Germany may keep its records in cruzeiros, invoice in German marks, and have DM-denominated receivables, and physically collect DM cash flow, only to find that its revenue stream behaves as if it were in U. S. dollars This occurs because DM-prices for each consecutive shipment are adjusted to reflect world market prices which, in turn, tend to be determined in U. S. dollars. The significance of this distinction is that the currency of denomination is (relatively) readily subject to management discretion, through the choice of invoicing currency. Prices and cash flows, however, are determined by competitive conditions which are beyond the immediate control of the firm. Yet an additional dimension of exchange risk involves the element of time . In the very short run, virtually all local currency prices for real goods and services (although not necessarily for financial assets) remain unchanged after an unexpected exchange rate change. However, over a longer period of time, prices and costs move inversely to spot rate changes the tendency is for Purchasing Power Parity and the Law of One Price to hold. In reality, this price adjustment process takes place over a great variety of time patterns. These patterns depend not only on the products involved, but also on market structure, the nature of competition, general business conditions, government policies such as price controls, and a number of other factors. Considerable work has been done on the phenomenon of pass-through of price changes caused by (unexpected) exchange rate changes. And yet, because all the factors that determine the extent and speed of pass-through are very firm-specific and can be analyzed only on a case-by-case basis at the level of the operating entity of the firm (or strategic business unit), generalizations remain difficult to make. Exhibit 6 summarizes the firm-specific effects of exchange rate changes on operating cash flows. Conceptually, though, it is important to determine the time frame within which the firm cannot react to (unexpected) rate changes by (1) raising prices (2) changing markets for inputs and outputs andor (3) adjusting production and sales volumes. Sometimes, at least one of these reactions is possible within a relatively short time at other times the firm is locked-in through contractual or strategic commitments extending considerably into the future. Indeed, those firms which are free to react instantaneously and fully to adverse (unexpected) rate changes are not subject to exchange risk. A further implication of the time-frame element is that exchange risk stems from the firms position when its cash flows are, for a significant period, exposed to (unexpected) exchange rate changes, rather than the risk resulting from any specific international involvement. Thus, companies engaged purely in domestic transactions but who have dominant foreign competitors may feel the effect of exchange rate changes in their cash flows as much or even more than some firms that are actively engaged in exports, imports, or foreign direct investment. 6 MANAGING ECONOMIC EXPOSURE 6 (a) Economic Effects of Unanticipated Exchange Rate Changes on Cash Flows . From this analytical framework, some practical implications emerge for the assessment of economic exposure. First of all, the firm must project its cost and revenue streams over a planning horizon that represents the period of time during which the firm is locked-in, or constrained from reacting to (unexpected) exchange rate changes. It must then assess the impact of a deviation of the actual exchange rate from the rate used in the projection of costs and revenues. STEPS IN MANAGING ECONOMIC EXPOSURE 1. Estimation of planning horizon as determined by reaction period. 2. Determination of expected future spot rate. 3. Estimation of expected revenue and cost streams, given the expected spot rate. 4. Estimation of effect on revenue and expense streams for unexpected exchange rate changes. 5. Choice of appropriate currency for debt denomination. 6. Estimation of necessary amount of foreign currency debt. 7. Determination of average interest period of debt. 8. Selection between direct or indirect debt denomination. 9. Decision on trade-off between arbitrage gains vs. exchange risk stemming from exposure in markets where rates are distorted by controls. 10. Decision about residual risk: consider adjusting business strategy. Subsequently, the effects on the various cash flows of the firm must be netted over product lines and markets to account for diversification effects where gains and losses could cancel out, wholly or in part. The remaining net loss or gain is the subject of economic exposure management. For a multiunit, multiproduct, multinational corporation the net exposure may not be very large at all because of the many offsetting effects.7 By contrast, enterprises that have invested in the development of one or two major foreign markets are typically subject to considerable fluctuations of their net cash flows, regardless of whether they invoice in their own or in the foreign currency. For practical purposes, three questions capture the extent of a companys foreign exchange exposure. 1. How quickly can the firm adjust prices to offset the impact of an unexpected exchange rate change on profit margins 2. How quickly can the firm change sources for inputs and markets for outputs Or, alternatively, how diversified are a companys factor and product markets 3. To what extent do volume changes, associated with unexpected exchange rate changes, have an impact on the value of assets Normally, the executives within business firms who can supply the best estimates on these issues tend to be those directly involved with purchasing, marketing, and production. Finance managers who focus exclusively on credit and foreign exchange markets may easily miss the essence of corporate foreign exchange risk. 6 (b) Financial versus operating strategies for hedging. When operating (cash) inflows and (contractual) outflows from liabilities are affected by exchange rate changes, the general principle of prudent exchange risk management is: any effect on cash inflows and outflows should cancel out as much as possible. This can be achieved by maneuvering assets, liabilities or both. When should operations -- the asset side -- be used We have demonstrated that exchange rate changes can have tremendous effects on operating cash flows. Does it not therefore make sense to adjust operations to hedge against these effects Many companies, such as Japanese auto producers, are now seeking flexibility in production location, in part to be able to respond to large and persistent exchange rate changes that make production much cheaper in one location than another. Among the operating policies are the shifting of markets for output, sources of supply, product-lines, and production facilities as a defensive reaction to adverse exchange rate changes. Put differently, deviations from purchasing power parity provide profit opportunities for the operations-flexible firm. This philosophy is epitomized in the following quotation. It has often been joked at Philips that in order to take advantage of currency movements, it would be a good idea to put our factories aboard a supertanker, which could put down anchor wherever exchange rates enable the company to function most efficiently. In the present currency markets. this would certainly not be a suitable means of transport for taking advantage of exchange rate movements. An aeroplane would be more in line with the requirements of the present era. The problem is that Philips production could not fit into either craft. It is obvious that such measures will be very costly, especially if undertaken over a short span of time. it follows that operating policies are not the tools of choice for exchange risk management. Hence operating policies which have been designed to reduce or eliminate exposure will only be undertaken as a last resort, when less expensive options have been exhausted. It is not surprising, therefore, that exposure management focuses not on the asset side, but primarily on the liability side of the firms balance sheet. Exhibit 7 provides a summary of the steps involved in managing economic exposure. Whether and how these steps should be implemented depends first, on the extent to which the firm wishes to rely on currency forecasting to make hedging decisions, and second, on the range of hedging tools available and their suitability to the task. These issues are addressed in the next two sections. 5 GUIDELINES FOR CORPORATE FORECASTING OF EXCHANGE RATES Academics and practitioners have sought the determinants of exchange rate changes ever since there were currencies. Many students have learned about the balance of trade and how the more a country exports, the more demand there is for its currency, and so the stronger is its exchange rate. In practice, the story is a lot more complex. Research in the foreign exchange markets have come a long way since the days when international trade was thought to be the dominant factor determining the level of the exchange rate. Monetary variables, capital flows, rational expectations and portfolio balance are all now understood to factor into the determination of currencies in a floating exchange rate system. Many models have been developed to explain and to forecast exchange rates. No model has yet proved to be the definitive one, perhaps because the structure of the worlds economies and financial markets are undergoing such rapid evolution. Corporations nevertheless avidly seek ways to predict currencies, in order to decide when and when not to hedge. The models they use are typically one or more of the following kinds: political event analysis . or fundamental . or technical . Academic students of international finance, in contrast, find strong empirical support for the role of arbitrage in global financial markets, and for the view that exchange rates exhibit behavior that is characteristic of other speculative asset markets. Exchange rates react quickly to news. Rates are far more volatile than changes in underlying economic variables they are moved by changing expectations, and hence are difficult to forecast. In a broad sense they are efficient, but tests of efficiency face inherent obstacles in testing the precise nature of this efficiency directly. The central efficient market model is the unbiased forward rate theory introduced earlier. It says that the forward rate equals the expected future level of the spot rate. Because the forward rate is a contractual price, it offers opportunities for speculative profits for those who correctly assess the future spot price relative to the current forward rate. Specifically, risk neutral players will seek to make a profit their forecast differs from the forward rate, so if there are enough such participants the forward rate will always be bid up or down until it equals the expected future spot. Because expectations of future spot rates are formed on the basis of presently available information (historical data) and an interpretation of its implication for the future, they tend to be subject to frequent and rapid revision. The actual future spot rate may therefore deviate markedly from the expectation embodied in the present forward rate for that maturity. The actual exchange rate may deviate from the expected by some random error. As is indicated in Exhibit 8, in an efficient market the forecasting error will be distributed randomly, according to some probability distribution, with a mean equal to zero. An implication of this is that todays forecast, as represented by the forward rate, is equal to yesterdays forward plus some random amount. In other words, the forward rate itself follows a random walk. Another way of looking at these errors to consider them as speculative profits or losses: what you would gain or lose of you consistently bet against the forward rate. Can they be consistently positive or negative A priori reasoning suggests that this should not be the case. Otherwise one would have to explain why consistent losers do not quit the market, or why consistent winners are not imitated by others or do not increase their volume of activity, thus causing adjustment of the forward rate in the direction of their expectation. Barring such explanation, one would expect that the forecast error is sometimes positive, sometimes negative, alternating in a random fashion, driven by unexpected events in the economic and political environment. Rigorously tested academic models have cast doubt on the pure unbiased forward rate theory of efficiency, and demonstrated the presence of speculative profit opportunities (for example, by the use of filter rules). However it is also logical to suppose that speculators will bear foreign exchange risk only if they are compensated with a risk premium. Are the above-zero expected returns excessive in a risk-adjusted sense Given the small size of the bias in the forward exchange market, and the magnitude of daily currency fluctuations, the answer is probably not. As a result of their finding that the foreign exchange markets are among the worlds most efficient, academics argue the exchange rate forecasting by corporations, in the sense of trying to beat the market, plays a role only under very special circumstances. Indeed few firms are actively decide to commit real assets in order to take currency positions. Rather, they get involved with foreign currencies in the course of pursuing profits from the exploitation of a competitive advantage rather than being based on currency expectations, this advantage is based on expertise in such areas as production, marketing, the organization of people, or other technical resources. If someone does have special expertise in forecasting foreign exchange rates, such skills can usually be put to use without incurring the risks and costs of committing funds to other than purely financial assets. Most finance managers of nonfinancial enterprises concentrate on producing and selling goods they should find themselves acting as speculative foreign exchange traders only because of an occasional opportunity encountered in the course of their normal operations. Only when foreign exchange markets are systematically distorted by government controls on financial institutions do the operations of trading and manufacturing firms provide an opportunity to move funds and gain from purely financial transactions. Exhibit 9 offers a flowchart of criteria for forecasting and hedging decisions. Forecasting exchange rate changes, however, is important for planning purposes. To the extent that all significant managerial tasks are concerned with the future, anticipated exchange rate changes are a major input into virtually all decisions of enterprises involved in and affected by international transactions. However, the task of forecasting foreign exchange rates for planning and decision-making purposes, with the purpose of determining the most likely exchange rate, is quite different from attempting to beat the market in order to derive speculative profits. Expected exchange rate changes are revealed by market prices when rates are free to reach their competitive levels. Organized futures or forward markets provide inexpensive information regarding future exchange rates, using the best available data and judgment. Thus, whenever profit-seeking, well-informed traders can take positions, forward rates, prices of future contracts, and interest differentials for instruments of similar riskiness (but denominated in different currencies), provide good indicators of expected exchange rates. In this fashion, an input for corporate planning and decision-making is readily available in all currencies where there are no effective exchange controls. The advantage of such market-based rates over in-house forecasts is that they are both less expensive and more likely to be accurate. Market rates are determined by those who tend to have the best information and track-record incompetent market participants lose money and are eliminated. The nature of this market-based expected exchange rate should not lead to confusing notions about the accuracy of prediction. In speculative markets, all decisions are made on the basis of interpretation of past data however, new information surfaces constantly. Therefore, market-based forecasts rarely will come true. The actual price of a currency will either be below or above the rate expected by the market. If the market knew which would be more likely, any predictive bias quickly would be corrected. Any predictable, economically meaningful bias would be corrected by the transactions of profit-seeking transactors. Example: Hedging with a Forward Contract Janet Fredericks, Foreign Exchange Manager at Murray Chemical, was informed that Murray was selling 25,000 tonnes of naphtha to Canada for a total price of C11,500,000, to be paid upon delivery in two months time. To protect her company, she arranged to sell 11.5 million Canadian dollars forward to the Royal Bank of Montreal. The two month forward contract price was US0.8785 per Canadian dollar. Two months and two days later, Fredericks received US10,102,750 from RBM and paid RBM C11,500,000, the amount received from Murrays customer. The importance of market-based forecasts for a determination of the foreign exchange exposure of the firm is that of a benchmark against which the economic consequences of deviations must be measured. This can be put in the form of a concrete question: How will the expected net cash flow of the firm behave if the future spot exchange rate is not equal to the rate predicted by the market when commitments are made The nature of this kind of forecast is completely different from trying to outguess the foreign exchange markets 7 TOOLS AND TECHNIQUES FOR THE MANAGEMENT OF FOREIGN EXCHANGE RISK In this section we consider the relative merits of several different tools for hedging exchange risk, including forwards, futures, debt, swaps and options. We will use the following criteria for contrasting the tools. First, there are different tools that serve effectively the same purpose. Most currency management instruments enable the firm to take a long or a short position to hedge an opposite short or long position. Thus one can hedge a DM payment using a forward exchange contract, or debt in DM, or futures or perhaps a currency swap. In equilibrium the cost of all will be the same, according to the fundamental relationships of the international money market as illustrated in Exhibit 1. They differ in details like default risk or transactions costs, or if there is some fundamental market imperfection. indeed in an efficient market one would expect the anticipated cost of hedging to be zero. This follows from the unbiased forward rate theory. Second, tools differ in that they hedge different risks. In particular, symmetric hedging tools like futures cannot easily hedge contingent cash flows: options may be better suited to the latter. 7 (a) Tools and techniques: foreign exchange forwards Foreign exchange is, of course, the exchange of one currency for another. Trading or dealing in each pair of currencies consists of two parts, the spot market . where payment (delivery) is made right away (in practice this means usually the second business day), and the forward market . The rate in the forward market is a price for foreign currency set at the time the transaction is agreed to but with the actual exchange, or delivery, taking place at a specified time in the future. While the amount of the transaction, the value date, the payments procedure, and the exchange rate are all determined in advance, no exchange of money takes place until the actual settlement date . This commitment to exchange currencies at a previously agreed exchange rate is usually referred to as a forward contract . Forward contracts are the most common means of hedging transactions in foreign currencies, as the example in Exhibit 10 illustrates. The trouble with forward contracts, however, is that they require future performance, and sometimes one party is unable to perform on the contract. When that happens, the hedge disappears, sometimes at great cost to the hedger. This default risk also means that many companies do not have access to the forward market in sufficient quantity to fully hedge their exchange exposure. For such situations, futures may be more suitable. 7 (b) Currency futures Outside of the interbank forward market, the best-developed market for hedging exchange rate risk is the currency futures market. In principle, currency futures are similar to foreign exchange forwards in that they are contracts for delivery of a certain amount of a foreign currency at some future date and at a known price. In practice, they differ from forward contracts in important ways. One difference between forwards and futures is standardization. Forwards are for any amount, as long as its big enough to be worth the dealers time, while futures are for standard amounts, each contract being far smaller that the average forward transaction. Futures are also standardized in terms of delivery date. The normal currency futures delivery dates are March, June, September and December, while forwards are private agreements that can specify any delivery date that the parties choose. Both of these features allow the futures contract to be tradable. Another difference is that forwards are traded by phone and telex and are completely independent of location or time. Futures, on the other hand, are traded in organized exchanges such the LIFFE in London, SIMEX in Singapore and the IMM in Chicago. But the most important feature of the futures contract is not its standardization or trading organization but in the time pattern of the cash flows between parties to the transaction. In a forward contract, whether it involves full delivery of the two currencies or just compensation of the net value, the transfer of funds takes place once: at maturity. With futures, cash changes hands every day during the life of the contract, or at least every day that has seen a change in the price of the contract. This daily cash compensation feature largely eliminates default risk. Thus forwards and futures serve similar purposes, and tend to have identical rates, but differ in their applicability. Most big companies use forwards futures tend to be used whenever credit risk may be a problem. 7 (c) Debt instead of forwards or futures Debt -- borrowing in the currency to which the firm is exposed or investing in interest-bearing assets to offset a foreign currency payment -- is a widely used hedging tool that serves much the same purpose as forward contracts. Consider an example. In Exhibit 10, Fredericks sold Canadian dollars forwards. Alternatively she could have used the Eurocurrency market to achieve the same objective. She would borrow Canadian dollars, which she would then change into francs in the spot market, and hold them in a US dollar deposit for two months. When payment in Canadian dollars was received from the customer, she would use the proceeds to pay down the Canadian dollar debt. Such a transaction is termed a money market hedge . The cost of this money market hedge is the difference between the Canadian dollar interest rate paid and the US dollar interest rate earned. According to the interest rate parity theorem . the interest differential equals the forward exchange premium, the percentage by which the forward rate differs from the spot exchange rate. So the cost of the money market hedge should be the same as the forward or futures market hedge, unless the firm has some advantage in one market or the other. The money market hedge suits many companies because they have to borrow anyway, so it simply is a matter of denominating the companys debt in the currency to which it is exposed. that is logical. but if a money market hedge is to be done for its own sake, as in the example just given, the firm ends up borrowing from one bank and lending to another, thus losing on the spread. This is costly, so the forward hedge would probably be more advantageous except where the firm had to borrow for ongoing purposes anyway. 7 (d) Currency options Many companies, banks and governments have extensive experience in the use of forward exchange contracts. With a forward contract one can lock in an exchange rate for the future. There are a number of circumstances, however, where it may be desirable to have more flexibility than a forward provides. For example a computer manufacturer in California may have sales priced in U. S. dollars as well as in German marks in Europe. Depending on the relative strength of the two currencies, revenues may be realized in either German marks or dollars. In such a situation the use of forward or futures would be inappropriate: theres no point in hedging something you might not have. What is called for is a foreign exchange option: the right, but not the obligation, to exchange currency at a predetermined rate. A foreign exchange option is a contract for future delivery of a currency in exchange for another, where the holder of the option has the right to buy (or sell) the currency at an agreed price, the strike or exercise price, but is not required to do so. The right to buy is a call the right to sell, a put . For such a right he pays a price called the option premium . The option seller receives the premium and is obliged to make (or take) delivery at the agreed-upon price if the buyer exercises his option. In some options, the instrument being delivered is the currency itself in others, a futures contract on the currency. American options permit the holder to exercise at any time before the expiration date European options, only on the expiration date. Steve Yamamoto of Frito-Lay had just agreed to purchase I5 million worth of potatoes from his supplier in County Cork, Ireland. Payment of the five million punt was to be made in 245 days time. The dollar had recently plummeted against all the EMS currencies and Yamamoto wanted to avoid any further rise in the cost of imports. He viewed the dollar as being extremely instable in the current environment of economic tensions. Having decided to hedge the payment, he had obtained dollarpunt quotes of 2.25 spot, 2.19 for 245 days forward delivery. His view, however, was that the dollar was bound to rise in the next few months, so he was strongly considering purchasing a call option instead of buying the punt forward. At a strike price of 2.21, the best quote he had been able to obtain was from the Ballad Bank of Dublin, who would charge a premium of 0.85 of the principal. Yamamoto decided to buy the call option. In effect, he reasoned, Im paying for downside protection while not limiting the possible savings I could reap if the dollar does recover to a more realistic level. In a highly volatile market where crazy currency values can be reached, options make more sense than taking your chances in the market, and youre not locked into a rock-bottom forward rate. This simple example illustrates the lopsided character of options. Futures and forwards are contracts in which two parties oblige themselves to exchange something in the future. They are thus useful to hedge or convert known currency or interest rate exposures. An option, in contrast, gives one party the right but not the obligation to buy or sell an asset under specified conditions while the other party assumes an obligation to sell or buy that asset if that option is exercised. Figure 1 illustrates the two possible outcomes of an option such as that bought by Steve Yamamoto. When should a company like Frito-Lay use options in preference to forwards or futures In the example, Yamamoto had a view on the currencys direction that differed from the forward rate. Taken alone, this would suggest taking a position. But he also had a view on the dollars volatility . Options provide the only convenient means of hedging or positioning volatility risk. Indeed the price of an option is directly influenced by the outlook for a currencys volatility: the more volatile, the higher the price. To Yamamoto, the price is worth paying. In other words he thinks the true volatility is greater than that reflected in the options price. This example highlights one set of circumstances under which a company should consider the use of options. A currency call or put options value is affected by both direction and volatility changes, and the price of such an option will be higher, the more the markets expectations (as reflected in the forward rate) favor exercise and the greater the anticipated volatility. For example, during the crisis in the European Monetary System of mid-1993, put options on the French franc became very expensive for two reasons. First, high French interest rates designed to support the franc drove the forward rate to a discount against the German mark. Second, anticipated volatility of the DMFF exchange rate jumped as dealers speculated on a possible break-up of the EMS. With movements much greater than the EMS official bands possible, the expected gain from exercising puts became much greater. It was an appropriate time for companies with French exposure to buy puts, but the cost would exceed the expected gain unless the corporate Treasury anticipated a greater change, or an even higher volatility, than those reflected in the market price of options. Finally, one can justify the limited use of options by reference to the deleterious effect of financial distress alluded to in section 2. Unmanaged exchange rate risk can cause significant fluctuations in the earnings and the market value of an international firm. A very large exchange rate movement may cause special problems for a particular company, perhaps because it brings a competitive threat from a different country. At some level, the currency change may threaten the firms viability, bringing the costs of bankruptcy to bear. To avert this, it may be worth buying some low-cost options that would pay off only under unusual circumstances, ones that would particularly hurt the firm. Out-of-the-money options may be a useful and cost-effective way to hedge against currency risks that have very low probabilities but which, if they occur, have disproportionately high costs to the company. 8 CONTROLLING CORPORATE TREASURY TRADING RISKS In a corporation, there is no such thing as being perfectly hedged. Not every transaction can be matched, for international trade and production is a complex and uncertain business. As we have seen, even identifying the correct currency of exposure, the currency of determination, is tricky. Flexibility is called for, and management must necessarily give some discretion, perhaps even a lot of discretion, to the corporate treasury department or whichever unit is charged with managing foreign exchange risks. Some companies, feeling that foreign exchange is best handled by professionals, hire ex-bank dealers other groom engineers or accountants. Yet however talented and honorable are these individuals, it has become evident that some limits must be imposed on the trading activities of the corporate treasury, for losses can get out of hand even in the best of companies. In 1992 a Wall Street Journal reporter found that Dell Computer Corporation, a star of the retail PC industry, had been trading currency options with a face value that exceeded Dells annual international sales, and that currency losses may have been covered up. Complex options trading was in part responsible for losses at the treasury of Allied-Lyons, the British foods group. The 150 million lost almost brought the company to its knees, and the publicity precipitated a management shake-out. In 1993 the oil giant Royal Dutch-Shell revealed that currency trading losses of as much as a billion dollars had been uncovered in its Japanese subsidiary. Clearly, performance measurement standards, accountability and limits of some form must be part of a treasury foreign currency hedging program. Space does not permit a detailed examination of trading control methods, but some broad principles can be stated. First, management must elucidate the goals of exchange risk management, preferably in operational terms rather than in platitudes such as we hedge all foreign exchange risks. Second, the risks of in-house trading (for thats often what it is) must be recognized. These include losses on open positions from exchange rate changes, counterparty credit risks, and operations risks. Third, for all net positions taken, the firm must have an independent method of valuing, marking-to-market, the instruments traded. This marking to market need not be included in external reports, if the positions offset other exposures that are not marked to market, but is necessary to avert hiding of losses. Wherever possible, marking to market should be based on external, objective prices traded in the market. Fourth, position limits should be made explicit rather than treated as a problem we would rather not discuss. Instead of hamstringing treasury with a complex set of rules, limits can take the form of prohibiting positions that could incur a loss (or gain) beyond a certain amount, based on sensitivity analysis. As in all these things, any attempt to cover up losses should reap severe penalties. Finally, counterparty risks resulting from over-the-counter forward or swap contracts should be evaluated in precisely the same manner as is done when the firm extends credit to, say, suppliers or customers. In all this, the chief financial officer might well seek the assistance of an accounting or consulting firm, and may wish to purchase software tailored to the purposes. This chapter offers the reader an introduction to the complex subject of the measurement and management of foreign exchange risk. We began by noting some problems with interpretation of the concept, and entered the debate as to whether and why companies should devote active managerial resources to something that is so difficult to define and measure. Accountants efforts to put an objective value on a firm involved in international business has led many to focus on the translated balance sheet as a target for hedging exposure. As was demonstrated, however, there are numerous realistic situations where the economic effects of exchange rate changes differ from those predicted by the various measures of translation exposure. In particular, we emphasized the distinctions between the currency of location, the currency of denomination, and the currency of determination of a business. After giving some guidelines for the management of economic exposure, the chapter addressed the thorny question of how to approach currency forecasting. We suggested a market-based approach to international financial planning, and cast doubt on the ability of the corporations treasury department to outperform the forward exchange rate. The chapter then turned to the tools and techniques of hedging, contrasting the applications that require forwards, futures, money market hedging, and currency options. In Exhibit 11, we present a sketch of how a company may approach the exchange risk management task, based on the principles laid out in this chapter. Sorry, not all exhibits appear in this version.

Note that when we say the forward rate follows a random walk, we mean the forward for a given delivery date, not the rolling 3-month forward. Since the only published measure of a forward rate for a given delivery date is the price of a futures contract, the latter serves as a proxy to test the proposition that the forward rate should fluctuate randomly. 5.

Saya akui, penilaian saya terhadap FPI sedikit berubah. Obrolan saya di Provocative Proaktif Radio dgn Mamot (bukan nama asli) seorang mantan anggota FPI, Pak Tamrin Tomagola seorang sosiolog dan Ketua FPI DPD Jakarta Habib Selon sangat menambah wawasan saya akan FPI, alasan pentas FPI ke PP radio adalah karena isu-isu FPI di Kalimantan. Penolakan yg tersayang di-di dalam kota di Indonesia Wacana pembubaran FPI muncul, banyak dukungan dalam bentuk tagar (tanda pagar) indonesiaTanpaFPI muncul di twitter. Ratusan orang aksi damai di jalananan menunjukkan barangnya Kalau kamu bertanya kepada saya, saya pribadi akan jawab tidak setuju terhadap pembubaran FPI. 1) Karena pembubaran FPI hanya akan membuat mereka muncul kembali dengan nama yg baru 2) Karena negara bebas untuk berkumpul dan berserikat. Menghalangi itu, hanya akan berdampak buruk kpd diri kita sendiri 3) Kalau FPI melakukan kegiatan2 yg melanggar hukum, ya pelakunya yg ditindak. Sama aja seperti misalnya POLRI ada yg melanggar h
