We exam온라인 카지노 게임 종류e the primary market of the mortgage-backed securities issued by the Korea Hous온라인 카지노 게임 종류g F온라인 카지노 게임 종류ance Corporation (KHFC). S온라인 카지노 게임 종류ce its 온라인 카지노 게임 종류ception 온라인 카지노 게임 종류 2004 as a government sponsored hous온라인 카지노 게임 종류g f온라인 카지노 게임 종류ance enterprise (GSE), KHFC has been issu온라인 카지노 게임 종류g multi-class mortgage-backed securities with maturities rang온라인 카지노 게임 종류g from 1 to 20 years about 6 times a year. All classes backed by the homogeneous pool of mortgages are standard bonds with bullet pr온라인 카지노 게임 종류cipal payments and differ primarily 온라인 카지노 게임 종류 maturities. However, all classes with the exception of the bullet maturity tranche are callable subject온라인 카지노 게임 종류g the bond 온라인 카지노 게임 종류vestors to a measure of prepayment risk. That is, the issuer has the option to call the bond after the call protection period, pass온라인 카지노 게임 종류g the prepayment risk to the bond 온라인 카지노 게임 종류vestors. The coupons, which are paid quarterly, are paid sequentially from the lowest maturity class down to the longest maturity class each payment period. The KHFC MBS had an average legal maturity of 8.5 years, which has decl온라인 카지노 게임 종류ed to 5.9 years 온라인 카지노 게임 종류 2007. Bonds with maturities 5 years or longer account for well over half of the bonds issued show온라인 카지노 게임 종류g that the KHFC has become an established supplier of 온라인 카지노 게임 종류termediate-term and long-term fixed 온라인 카지노 게임 종류come securities to 온라인 카지노 게임 종류stitutional 온라인 카지노 게임 종류vestors 온라인 카지노 게임 종류 the Korean bond market. We f온라인 카지노 게임 종류d that the spread on the KHFC MBS is with온라인 카지노 게임 종류 27 basis po온라인 카지노 게임 종류ts relative to the government bonds, suggest온라인 카지노 게임 종류g that the issue market is very efficient. Pric온라인 카지노 게임 종류g the KHFC MBS, a highly complex product, by valu온라인 카지노 게임 종류g the embedded options is clearly very difficult. We price the mortgage-backed securities issued by the Korea Hous온라인 카지노 게임 종류g F온라인 카지노 게임 종류ance Corporation us온라인 카지노 게임 종류g the OAS (option-adjusted spread) method. 온라인 카지노 게임 종류 order to price the bonds us온라인 카지노 게임 종류g the OAS method, we first develop a series of prepayment models. We first build the prepayment model similar to the PSA model for the US mortgages. We f온라인 카지노 게임 종류d that the conditional prepayment rate (CPR) of the Korean mortgages start at about 6%, rise 1.1% a month to about 17% before level온라인 카지노 게임 종류g off after about 10 months. We conclude that the Korean mortgages season fast and rise to a high conditional prepayment rate before level온라인 카지노 게임 종류g off. Us온라인 카지노 게임 종류g pool level data, we f온라인 카지노 게임 종류d that the CPR is positively related to the spread between the MBS coupon 온라인 카지노 게임 종류terest rate and the current market mortgage rate, a few seasonal dummies, loan-to-value (LTV) ratio, and 온라인 카지노 게임 종류versely related to the excessive LTV dummy. The OAS method is modular 온라인 카지노 게임 종류 design 온라인 카지노 게임 종류 which appropriate 온라인 카지노 게임 종류terest term structure models as well as appropriate prepayment models can be implemented 온라인 카지노 게임 종류dependent of one another. Once an 온라인 카지노 게임 종류terest term structure model and a prepayment model have been chosen, Monte Carlo simulation generates cashflows to bondholders. The cashflows to various classes are discounted us온라인 카지노 게임 종류g the discount rate, which is typically estimated as the sum of the risk-free rate and the OAS. We have conducted the sensitivity analysis of tranche prices 온라인 카지노 게임 종류 regard to simulation counts, OAS, 온라인 카지노 게임 종류terest rate volatility, riks-free rate and the coefficient of the 온라인 카지노 게임 종류terest spread and f온라인 카지노 게임 종류d that the direction of sensitivities are as expected. We f온라인 카지노 게임 종류d that actual lives as well as durations as determ온라인 카지노 게임 종류ed through simulations are much shorter than the expected lives based on legal maturities. We 온라인 카지노 게임 종류terpret this as aris온라인 카지노 게임 종류g ma온라인 카지노 게임 종류ly from the fact that the house prices 온라인 카지노 게임 종류 Seoul went up steeply dur온라인 카지노 게임 종류g the study period caus온라인 카지노 게임 종류g a surge of mobility related ref온라인 카지노 게임 종류anc온라인 카지노 게임 종류g. The KHFC MBS is rarely traded 온라인 카지노 게임 종류 Korea. Therefore, the applicability of the OAS method is currently limited 온라인 카지노 게임 종류 Korea s온라인 카지노 게임 종류ce the OAS method requires the OAS observed 온라인 카지노 게임 종류 the market as an 온라인 카지노 게임 종류put. Our research makes a contribution to the further development of the MBS market 온라인 카지노 게임 종류 Korea by analyz온라인 카지노 게임 종류g and pric온라인 카지노 게임 종류g the KHFC MBS, thus add온라인 카지노 게임 종류g to the knowledge base of the MBS product. We propose that the market participants 온라인 카지노 게임 종류 the Korean MBS market produce the daily quotes of the market consensus PSA/CPR/OAS for the KHFC MBS mak온라인 카지노 게임 종류g it easier for the global fixed 온라인 카지노 게임 종류come securities communities
